Nanotechnology  

Science Journals Connector (OSTI)

Abstract The antimicrobial properties of nanomaterials have promoted the use of nanotechnology to increase the shelf life of produce, meat, and other edible items. There is a knowledge gap regarding how engineered nanoparticles – or the products and materials that contain them – interact with the biological system and what is the environmental fate of these products. This article is focused on the current and potential uses of nanotechnology in food to improve human health, with an emphasis on prevention of microbial contamination.

Local non-equilibrium thermodynamics  

E-Print Network (OSTI)

Local Shannon entropy lies at the heart of modern thermodynamics, with much discussion of trajectory-dependent entropy production. When taken at both boundaries of a process in phase space, it reproduces the second law of thermodynamics over a finite time interval for small scale systems. However, given that entropy is an ensemble property, it has never been clear how one can assign such a quantity locally. Given such a fundamental omission in our knowledge, we construct a new ensemble composed of trajectories reaching an individual microstate, and show that locally defined entropy, information, and free energy are properties of the ensemble, or trajectory-independent true thermodynamic potentials. We find that the Boltzmann-Gibbs distribution and Landauer's principle can be generalized naturally as properties of the ensemble, and that trajectory-free state functions of the ensemble govern the exact mechanism of non-equilibrium relaxation.

Non-equilibrium many body dynamics  

SciTech Connect

This Riken BNL Research Center Symposium on Non-Equilibrium Many Body Physics was held on September 23-25, 1997 as part of the official opening ceremony of the Center at Brookhaven National Lab. A major objective of theoretical work at the center is to elaborate on the full spectrum of strong interaction physics based on QCD, including the physics of confinement and chiral symmetry breaking, the parton structure of hadrons and nuclei, and the phenomenology of ultra-relativistic nuclear collisions related to the up-coming experiments at RHIC. The opportunities and challenges of nuclear and particle physics in this area naturally involve aspects of the many body problem common to many other fields. The aim of this symposium was to find common theoretical threads in the area of non-equilibrium physics and modern transport theories. The program consisted of invited talks on a variety topics from the fields of atomic, condensed matter, plasma, astrophysics, cosmology, and chemistry, in addition to nuclear and particle physics. Separate abstracts have been indexed into the database for contributions to this workshop.

Non-equilibrium Thermodynamics of Spacetime  

E-Print Network (OSTI)

It has previously been shown that the Einstein equation can be derived from the requirement that the Clausius relation dS = dQ/T hold for all local acceleration horizons through each spacetime point, where dS is one quarter the horizon area change in Planck units, and dQ and T are the energy flux across the horizon and Unruh temperature seen by an accelerating observer just inside the horizon. Here we show that a curvature correction to the entropy that is polynomial in the Ricci scalar requires a non-equilibrium treatment. The corresponding field equation is derived from the entropy balance relation dS =dQ/T+dS_i, where dS_i is a bulk viscosity entropy production term that we determine by imposing energy-momentum conservation. Entropy production can also be included in pure Einstein theory by allowing for shear viscosity of the horizon.

Energy-exchange stochastic models for non-equilibrium  

E-Print Network (OSTI)

Non-equilibrium steady states are subject to intense investigations but still poorly understood. For instance, the derivation of Fourier law in Hamiltonian systems is a problem that still poses several obstacles. In order to investigate non-equilibrium systems, stochastic models of energy-exchange have been introduced and they have been used to identify universal properties of non-equilibrium. In these notes, after a brief review of the problem of anomalous transport in 1-dimensional Hamiltonian systems, some boundary-driven interacting random systems are considered and the "duality approach" to their rigorous mathematical treatment is reviewed. Duality theory, of which a brief introduction is given, is a powerful technique to deal with Markov processes and interacting particle systems. The content of these notes is mainly based on the papers [10, 11, 12].

DSMC predictions of non-equilibrium reaction rates.  

SciTech Connect

A set of Direct Simulation Monte Carlo (DSMC) chemical-reaction models recently proposed by Bird and based solely on the collision energy and the vibrational energy levels of the species involved is applied to calculate nonequilibrium chemical-reaction rates for atmospheric reactions in hypersonic flows. The DSMC non-equilibrium model predictions are in good agreement with theoretical models and experimental measurements. The observed agreement provides strong evidence that modeling chemical reactions using only the collision energy and the vibrational energy levels provides an accurate method for predicting non-equilibrium chemical-reaction rates.

Steady quantum coherence in non-equilibrium environment  

E-Print Network (OSTI)

We study the steady state of a three-level system in contact with a non-equilibrium environment, which is composed of two independent heat baths at different temperatures. We derive a master equation to describe the non-equilibrium process of the system. For the three level systems with two dipole transitions, i.e., the $\\Lambda$-type and V-type, we find that the interferences of two transitions in a non-equilibrium environment can give rise to non-vanishing steady quantum coherence, namely, there exist non-zero off-diagonal terms in the steady state density matrix (in the energy representation). Moreover, the non-vanishing off-diagonal terms increase with the temperature difference of the two heat baths. Such interferences of the transitions were usually omitted by secular approximation, for it was usually believed that they only take effect in short time behavior and do not affect the steady state. Here we show that, in non-equilibrium systems, such omission would lead to the neglect of the steady quantum coherence.

Non-equilibrium fission processes in intermediate energy nuclear collisions  

SciTech Connect

We have measured the target fragment yields, angular and energy distributions for the interaction of 12-16 MeV/A/sup 32/S with /sup 165/Ho and /sup 197/Au and for the interaction of 32 and 44 MeV/A /sup 40/Ar with /sup 197/Au. The Au fission fragments associated with the peripheral collision peak in the folding angle distribution originate in a normal, ''slow'' fission process in which statistical equilibrium has been established. At the two lowest projectile energies, the Au fission fragments associated with the central collision peak in the folding angle distribution originate in part from ''fast'' (/tau//approximately//sup /minus/23/s), non-equilibrium processes. Most of the Ho fission fragments originate in non- equilibrium processes. The fast, non-equilibrium process giving rise to these fragments has many of the characteristics of ''fast fission'', but the cross sections associated with these fragments are larger than one would expect from current theories of ''fast fission.

Non-equilibrium electromagnetic fluctuations: Heat transfer and interactions  

E-Print Network (OSTI)

The Casimir force between arbitrary objects in equilibrium is related to scattering from individual bodies. We extend this approach to heat transfer and Casimir forces in non-equilibrium cases where each body, and the environment, is at a different temperature. The formalism tracks the radiation from each body and its scatterings by the other objects. We discuss the radiation from a cylinder, emphasizing its polarized nature, and obtain the heat transfer between a sphere and a plate, demonstrating the validity of proximity transfer approximation at close separations and arbitrary temperatures.

Non-Equilibrium Conformal Field Theories with Impurities  

E-Print Network (OSTI)

We present a construction of non-equilibrium steady states within conformal field theory. These states sustain energy flows between two quantum systems, initially prepared at different temperatures, whose dynamical properties are represented by two, possibly different, conformal field theories connected through an impurity. This construction relies on a real time formulation of conformal defect dynamics based on a field scattering picture parallelizing - but yet different from - the Euclidean formulation. We present the basic characteristics of this formulation and give an algebraic construction of the real time scattering maps that we illustrate in the case of SU(2)-based conformal field theories.

Non-equilibrium Statistical Approach to Friction Models  

E-Print Network (OSTI)

A geometric approach to the friction phenomena is presented. It is based on the holographic view which has recently been popular in the theoretical physics community. We see the system in one-dimension-higher space. The heat-producing phenomena are most widely treated by using the non-equilibrium statistical physics. We take 2 models of the earthquake. The dissipative systems are here formulated from the geometric standpoint. The statistical fluctuation is taken into account by using the (generalized) Feynman's path-integral.

Non-equilibrium magnetic interactions in strongly correlated systems  

SciTech Connect

We formulate a low-energy theory for the magnetic interactions between electrons in the multi-band Hubbard model under non-equilibrium conditions determined by an external time-dependent electric field which simulates laser-induced spin dynamics. We derive expressions for dynamical exchange parameters in terms of non-equilibrium electronic Green functions and self-energies, which can be computed, e.g., with the methods of time-dependent dynamical mean-field theory. Moreover, we find that a correct description of the system requires, in addition to exchange, a new kind of magnetic interaction, that we name twist exchange, which formally resembles Dzyaloshinskii–Moriya coupling, but is not due to spin–orbit, and is actually due to an effective three-spin interaction. Our theory allows the evaluation of the related time-dependent parameters as well. -- Highlights: •We develop a theory for magnetism of strongly correlated systems out of equilibrium. •Our theory is suitable for laser-induced ultrafast magnetization dynamics. •We write time-dependent exchange parameters in terms of electronic Green functions. •We find a new magnetic interaction, a “twist exchange”. •We give general expressions for magnetic noise in itinerant-electron systems.

We report non-equilibrium molecular dynamics simulations of heat transport in models of molecular fluids. We show that the “local” thermal conductivities obtained from non-equilibrium molecular dynamics simulations agree within numerical accuracy with equilibrium Green-Kubo computations. Our results support the local equilibrium hypothesis for transport properties. We show how to use the local dependence of the thermal gradients to quantify the thermal conductivity of molecular fluids for a wide range of thermodynamic states using a single simulation.

Heating of thermal non-equilibrium ions by Alfvén wave via nonresonant interaction  

SciTech Connect

Pickup of thermal non-equilibrium ions by Alfvén wave via nonresonant wave-particle interaction is investigated by means of analytical test-particle theory. Some interesting and new results are found. No matter what the initial velocity distribution is, if the background magnetic field, the Alfvén speed, and the Alfvén magnetic field are fixed, the average parallel velocity never changes when t??. Heating effects in the perpendicular and parallel direction just depend on the initial temperature, and the perpendicular temperature increase is more prominent. It is noted that the heating effect of thermal non-equilibrium ions (Kappa ions) is weaker than that of the Maxwellian. This phenomenon may be relative to the heating of ions in the solar corona as well as in some toroidal confinement fusion devices.

We first consider high driving velocities and demonstrate that both systems are in the same universality class and undergo a strongly anisotropic non-equilibrium phase transition, with anisotropy exponent \\theta=3. Within a field theoretical ansatz the simulation results are confirmed. The crossover from Ising to mean field behavior in dependency of system size and driving velocity is analyzed using crossover scaling. It turns out that for all finite velocities the phase transition becomes strongly anisotropic in the thermodynamic limit.

Non-equilibrium phase transition in an exactly solvable driven Ising model with friction  

E-Print Network (OSTI)

A driven Ising model with friction due to magnetic correlations has recently been proposed by Kadau et al. (Phys. Rev. Lett. 101, 137205 (2008)). The non-equilibrium phase transition present in this system is investigated in detail using analytical methods as well as Monte Carlo simulations. In the limit of high driving velocities $v$ the model shows mean field behavior due to dimensional reduction and can be solved exactly for various geometries. The simulations are performed with three different single spin flip rates: the common Metropolis and Glauber rates as well as a multiplicative rate. Due to the non-equilibrium nature of the model all rates lead to different critical temperatures at $v>0$, while the exact solution matches the multiplicative rate. Finally, the cross-over from Ising to mean field behavior as function of velocity and system size is analysed in one and two dimensions.

Non-equilibrium thermodynamics of dark energy on the power-law entropy corrected apparent horizon  

E-Print Network (OSTI)

We investigate the Friedmann-Robertson-Walker (FRW) universe (containing dark energy) as a non-equilibrium (irreversible) thermodynamical system by considering the power-law correction to the horizon entropy. By taking power-law entropy area law which appear in dealing with the entanglement of quantum fields in and out the horizon, we determine the power-law entropy corrected apparent horizon of the FRW universe.

Phase-field investigation on the non-equilibrium interface dynamics of rapid alloy solidification  

SciTech Connect

The research program reported here is focused on critical issues that represent conspicuous gaps in current understanding of rapid solidification, limiting our ability to predict and control microstructural evolution (i.e. morphological dynamics and microsegregation) at high undercooling, where conditions depart significantly from local equilibrium. More specifically, through careful application of phase-field modeling, using appropriate thin-interface and anti-trapping corrections and addressing important details such as transient effects and a velocity-dependent (i.e. adaptive) numerics, the current analysis provides a reasonable simulation-based picture of non-equilibrium solute partitioning and the corresponding oscillatory dynamics associated with single-phase rapid solidification and show that this method is a suitable means for a self-consistent simulation of transient behavior and operating point selection under rapid growth conditions. Moving beyond the limitations of conventional theoretical/analytical treatments of non-equilibrium solute partitioning, these results serve to substantiate recent experimental findings and analytical treatments for single-phase rapid solidification. The departure from the equilibrium solid concentration at the solid-liquid interface was often observed during rapid solidification, and the energetic associated non-equilibrium solute partitioning has been treated in detail, providing possible ranges of interface concentrations for a given growth condition. Use of these treatments for analytical description of specific single-phase dendritic and cellular operating point selection, however, requires a model for solute partitioning under a given set of growth conditions. Therefore, analytical solute trapping models which describe the chemical partitioning as a function of steady state interface velocities have been developed and widely utilized in most of the theoretical investigations of rapid solidification. However, these solute trapping models are not rigorously verified due to the difficulty in experimentally measuring under rapid growth conditions. Moreover, since these solute trapping models include kinetic parameters which are difficult to directly measure from experiments, application of the solute trapping models or the associated analytic rapid solidification model is limited. These theoretical models for steady state rapid solidification which incorporate the solute trapping models do not describe the interdependency of solute diffusion, interface kinetics, and alloy thermodynamics. The phase-field approach allows calculating, spontaneously, the non-equilibrium growth effects of alloys and the associated time-dependent growth dynamics, without making the assumptions that solute partitioning is an explicit function of velocity, as is the current convention. In the research described here, by utilizing the phase-field model in the thin-interface limit, incorporating the anti-trapping current term, more quantitatively valid interface kinetics and solute diffusion across the interface are calculated. In order to sufficiently resolve the physical length scales (i.e. interface thickness and diffusion boundary length), grid spacings are continually adjusted in calculations. The full trajectories of transient planar growth dynamics under rapid directional solidification conditions with different pulling velocities are described. As a validation of a model, the predicted steady state conditions are consistent with the analytic approach for rapid growth. It was confirmed that rapid interface dynamics exhibits the abrupt acceleration of the planar front when the effect of the non-equilibrium solute partitioning at the interface becomes signi ficant. This is consistent with the previous linear stability analysis for the non-equilibrium interface dynamics. With an appropriate growth condition, the continuous oscillation dynamics was able to be simulated using continually adjusting grid spacings. This oscillatory dynamics including instantaneous jump of interface velocities are consistent

NON-EQUILIBRIUM IONIZATION MODELING OF THE CURRENT SHEET IN A SIMULATED SOLAR ERUPTION  

SciTech Connect

The current sheet that extends from the top of flare loops and connects to an associated flux rope is a common structure in models of coronal mass ejections (CMEs). To understand the observational properties of CME current sheets, we generated predictions from a flare/CME model to be compared with observations. We use a simulation of a large-scale CME current sheet previously reported by Reeves et al. This simulation includes ohmic and coronal heating, thermal conduction, and radiative cooling in the energy equation. Using the results of this simulation, we perform time-dependent ionization calculations of the flow in a CME current sheet and construct two-dimensional spatial distributions of ionic charge states for multiple chemical elements. We use the filter responses from the Atmospheric Imaging Assembly (AIA) on the Solar Dynamics Observatory and the predicted intensities of emission lines to compute the count rates for each of the AIA bands. The results show differences in the emission line intensities between equilibrium and non-equilibrium ionization. The current sheet plasma is underionized at low heights and overionized at large heights. At low heights in the current sheet, the intensities of the AIA 94 A and 131 A channels are lower for non-equilibrium ionization than for equilibrium ionization. At large heights, these intensities are higher for non-equilibrium ionization than for equilibrium ionization inside the current sheet. The assumption of ionization equilibrium would lead to a significant underestimate of the temperature low in the current sheet and overestimate at larger heights. We also calculate the intensities of ultraviolet lines and predict emission features to be compared with events from the Ultraviolet Coronagraph Spectrometer on the Solar and Heliospheric Observatory, including a low-intensity region around the current sheet corresponding to this model.

Fundamental Properties of Non-equilibrium Laser-Supported Detonation Wave  

SciTech Connect

For developing laser propulsion, it is very important to analyze the mechanism of Laser-Supported Detonation (LSD), because it can generate high pressure and high temperature to be used by laser propulsion can be categorized as one type of hypersonic reacting flows, where exothermicity is supplied not by chemical reaction but by radiation absorption. I have numerically simulated the 1-D and Quasi-1-D LSD waves propagating through an inert gas, which absorbs CO2 gasdynamic laser, using a 2-temperature model. Calculated results show the fundamental properties of the non-equilibrium LSD Waves.

THERMAL NON-EQUILIBRIUM REVISITED: A HEATING MODEL FOR CORONAL LOOPS  

SciTech Connect

The location and frequency of events that heat the million-degree corona are still a matter of debate. One potential heating scenario is that the energy release is effectively steady and highly localized at the footpoints of coronal structures. Such an energy deposition drives thermal non-equilibrium solutions in the hydrodynamic equations in longer loops. This heating scenario was considered and discarded by Klimchuk et al. on the basis of their one-dimensional simulations as incapable of reproducing observational characteristics of loops. In this paper, we use three-dimensional simulations to generate synthetic emission images, from which we select and analyze six loops. The main differences between our model and that of Klimchuk et al. concern (1) dimensionality, (2) resolution, (3) geometrical properties of the loops, (4) heating function, and (5) radiative function. We find evidence, in this small set of simulated loops, that the evolution of the light curves, the variation of temperature along the loops, the density profile, and the absence of small-scale structures are compatible with the characteristics of observed loops. We conclude that quasi-steady footpoint heating that drives thermal non-equilibrium solutions cannot yet be ruled out as a viable heating scenario for EUV loops.

Heavy-ion collisions with non-equilibrium Dirac-Brueckner mean fields  

Science Journals Connector (OSTI)

The influence of realistic interactions on the reaction dynamics in intermediate energy heavy-ion collisions is investigated. The mean field in relativistic transport calculations is derived from microscopic Dirac-Brueckner (DB) self-energies, taking non-equilibrium effects, in particular the anisotropy of the local phase space configurations, into account. Thus this approach goes beyond the local density approximation. A detailed analysis of various in-plane and out-of-plane flow observables is presented for Au on Au reactions at incident energies ranging from 250 to 800 A MeV and the results are compared to recent measurements of the FOPI Collaboration. An overall good agreement with in-plane flow data and a reasonable description of the out-of-plane emission is achieved. For these results the intrinsic momentum dependence of the non-equilibrium mean fields is important. On the other hand, the local density approximation with the same underlying DB forces as well as a standard non-linear version of the ?? model are less successful in describing the present data. This gives evidence of the applicability of self-energies derived from the DB approach to nuclear matter also far from saturation and equilibrium.

A definition of thermodynamic entropy valid for non-equilibrium states and few-particle systems  

E-Print Network (OSTI)

From a new rigorous formulation of the general axiomatic foundations of thermodynamics we derive an operational definition of entropy that responds to the emergent need in many technological frameworks to understand and deploy thermodynamic entropy well beyond the traditional realm of equilibrium states of macroscopic systems. The new definition is achieved by avoiding to resort to the traditional concepts of "heat" (which restricts $a$ $priori$ the traditional definitions of entropy to the equilibrium domain) and of "thermal reservoir" (which restricts $in$ $practice$ our previous definitions of non-equilibrium entropy to the many-particle domain). The measurement procedure that defines entropy is free from intrinsic limitations and can be applied, $in$ $principle$, even to non-equilibrium states of few-particle systems, provided they are separable and uncorrelated. The construction starts from a previously developed set of carefully worded operational definitions for all the basic concepts. Then, through a new set of fully spelled-out fundamental hypotheses (four postulates and five assumptions) we derive the definitions of energy and entropy of any state, and of temperature of any stable equilibrium state. Finally, we prove the principle of entropy non-decrease, the additivity of entropy differences, the maximum entropy principle, and the impossibility of existence of a thermal reservoir.

Driving kinetically constrained models into non-equilibrium steady states: structural and slow transport properties  

E-Print Network (OSTI)

Complex fluids in shear flow and biased dynamics in crowded environments exhibit counterintuitive features which are difficult to address both at theoretical level and by molecular dynamic simulations. To understand some of these features we study a schematic model of highly viscous liquid, the 2D Kob-Andersen kinetically constrained model, driven into non-equilibrium steady states by a uniform non-Hamiltonian force. We present a detailed numerical analysis of the microscopic behavior of the model, including transversal and longitudinal spatial correlations and dynamic heterogeneities. In particular, we show that at high particle density the transition from positive to negative resistance regimes in the current vs field relation can be explained via the emergence of nontrivial structures that intermittently trap the particles and slow down the dynamics. We relate such spatial structures to the current vs field relation in the different transport regimes.

Cloud formation modelling is an integral part of any atmosphere simulation used to interpret spectral observations of ultra-cool objects and to determine fundamental parameters like log(g) and Teff. This proceeding to the workshop 'GAIA and the Unseen: The Brown Dwarf Question' first summarizes what a model atmosphere simulation is, and then advocates two ideas: A) The use of a multitude of model families to determine fundamental parameters with realistic confidence interval. B) To keep an eye on the unexpected, like for example, ionisation signatures resulting plasma processes

Non-Equilibrium Superconductivity in Kinetic Inductance Detectors for THz Photon Sensing  

E-Print Network (OSTI)

Low temperature Kinetic Inductance Detectors (KIDs) are attractive candidates for producing quantumsensitive, arrayable sensors for astrophysical and other precision measurement applications. The readout uses a low frequency probe signal with quanta of energy well-below the threshold for pair-breaking in the superconductor. We have calculated the detailed non-equilibrium quasiparticle and phonon energy spectra generated by the probe signal of the KID when operating well-below its superconducting transition temperature Tc within the framework of the coupled kinetic equations described by Chang and Scalapino.[1] At the lowest bath temperature studied Tb/Tc = 0.1 the quasiparticle distributions can be driven far from equilibrium. In addition to the low frequency probe signal we have incorporated a high frequency (~ 1 THz) source signal well-above the pair-breaking threshold of the superconductor. Calculations of source signal detection efficiency are discussed

Exponential approach to, and properties of, a non-equilibrium steady state in a dilute gas  

E-Print Network (OSTI)

We investigate a kinetic model of a system in contact with several thermal reservoirs at different temperatures $T_\\alpha$. Our system is a spatially uniform dilute gas whose internal dynamics is described by the nonlinear Boltzmann equation with Maxwellian collisions. Similarly, the interaction with reservoir $\\alpha$ is represented by a Markovian process that has the Maxwellian $M_{T_\\alpha}$ as its stationary state. We prove existence and uniqueness of a non-equilibrium steady state (NESS) and show exponential convergence to this NESS in a metric on probability measures introduced into the study of Maxwellian collisions by Gabetta, Toscani and Wenberg (GTW). This shows that the GTW distance between the current velocity distribution to the steady-state velocity distribution is a Lyapunov functional for the system. We also derive expressions for the entropy production in the system plus the reservoirs which is always positive.

Interacting dark fluid in the universe bounded by event horizon : A non-equilibrium prescription  

E-Print Network (OSTI)

A non-equilibrium thermodynamic analysis has been done for the interacting dark fluid in the universe bounded by the event horizon.From observational evidences it is assumed that at present the matter in the universe is dominated by two dark sectors-dark matter and dark energy. The mutual interaction among them results in spontaneous heat flow between the horizon and the fluid system and the thermal equilibrium will no longer hold.In the present work,the dark matter is chosen in the form of dust while the dark energy is chosen as a perfect fluid with constant equation in one case and holographic dark energy model is chosen in the other.Finally,validity of the generalized second law of thermodynamics has been examined in both cases.

NON-EQUILIBRIUM THERMODYNAMIC PROCESSES: SPACE PLASMAS AND THE INNER HELIOSHEATH  

SciTech Connect

Recently, empirical kappa distribution, commonly used to describe non-equilibrium systems like space plasmas, has been connected with non-extensive statistical mechanics. Here we show how a consistent definition of the temperature and pressure is developed for stationary states out of thermal equilibrium, so that the familiar ideal gas state equation still holds. In addition to the classical triplet of temperature, pressure, and density, this generalization requires the kappa index as a fourth independent thermodynamic variable that characterizes the non-equilibrium stationary states. All four of these thermodynamic variables have key roles in describing the governing thermodynamical processes and transitions in space plasmas. We introduce a novel characterization of isothermal and isobaric processes that describe a system's transition into different stationary states by varying the kappa index. In addition, we show how the variation of temperature or/and pressure can occur through an 'iso-q' process, in which the system remains in a fixed stationary state (fixed kappa index). These processes have been detected in the proton plasma in the inner heliosheath via specialized data analysis of energetic neutral atom (ENA) observations from Interstellar Boundary Explorer. In particular, we find that the temperature is highly correlated with (1) kappa, asymptotically related to isothermal ({approx}1,000,000 K) and iso-q ({kappa} {approx} 1.7) processes; and (2) density, related to an isobaric process, which separates the 'Ribbon', P Almost-Equal-To 3.2 pdyn cm{sup -2}, from the globally distributed ENA flux, P Almost-Equal-To 2 pdyn cm{sup -2}.

Many-body current formula and current conservation for non-equilibrium fully interacting nanojunctions  

Science Journals Connector (OSTI)

We consider the electron transport properties through fully interacting nanoscale junctions beyond the linear-response regime. We calculate the current flowing through an interacting region connected to two interacting leads, with interaction crossing at the left and right contacts, by using a non-equilibrium Green function technique. The total current at one interface (the left one for example) is made of several terms which can be regrouped into two sets. The first set corresponds to a very generalized Landauer-like current formula with physical quantities defined only in the interacting central region and with renormalized lead self-energies. The second set characterizes inelastic scattering events occurring in the left lead. We show how this term can be negligible or even vanish due to the pseudo-equilibrium statistical properties of the lead in the thermodynamic limit. The expressions for the different Green functions needed for practical calculations of the current are also provided. We determine the constraints imposed by the physical condition of current conservation. The corresponding equation imposed on the different self-energy quantities arising from the current conservation is derived. We discuss in detail its physical interpretation and its relation with previously derived expressions. Finally several important key features are discussed in relation to the implementation of our formalism for calculations of quantum transport in realistic systems.

Cosmological QCD phase transition in steady non-equilibrium dissipative Ho?ava-Lifshitz early universe  

E-Print Network (OSTI)

We study the phase transition from quark-gluon plasma to hadrons in the early universe in the context of non-equilibrium thermodynamics. According to the standard model of cosmology, a phase transition associated with chiral symmetry breaking after the electro-weak transition has occurred when the universe was about $1-10\\mu s$ old. We focus attention on such a phase transition in the presence of a viscous relativistic cosmological background fluid in the framework of non-detailed balance Ho\\v{r}ava-Lifshitz cosmology within an effective model of QCD. We consider a flat Friedmann-Robertson-Walker Universe filled with a non-causal and causal bulk viscous cosmological fluid respectively and investigate the effects of the running coupling constants of Ho\\v{r}ava-Lifshitz gravity, $\\lambda$, on the evolution of the physical quantities relevant to a description of the early universe, namely, the temperature $T$, scale factor $a$, deceleration parameter $q$ and dimensionless ratio of the bulk viscosity coefficient to entropy density $\\frac{\\xi}{s}$. We assume that the bulk viscosity cosmological background fluid obeys the evolution equation of the steady truncated (Eckart) and full version of the Israel-Stewart fluid, respectively.

A numerical model of non-equilibrium thermal plasmas. I. Transport properties  

SciTech Connect

A self-consistent and complete numerical model for investigating the fundamental processes in a non-equilibrium thermal plasma system consists of the governing equations and the corresponding physical properties of the plasmas. In this paper, a new kinetic theory of the transport properties of two-temperature (2-T) plasmas, based on the solution of the Boltzmann equation using a modified Chapman-Enskog method, is presented. This work is motivated by the large discrepancies between the theories for the calculation of the transport properties of 2-T plasmas proposed by different authors in previous publications. In the present paper, the coupling between electrons and heavy species is taken into account, but reasonable simplifications are adopted, based on the physical fact that m{sub e}/m{sub h} Much-Less-Than 1, where m{sub e} and m{sub h} are, respectively, the masses of electrons and heavy species. A new set of formulas for the transport coefficients of 2-T plasmas is obtained. The new theory has important physical and practical advantages over previous approaches. In particular, the diffusion coefficients are complete and satisfy the mass conversation law due to the consideration of the coupling between electrons and heavy species. Moreover, this essential requirement is satisfied without increasing the complexity of the transport coefficient formulas. Expressions for the 2-T combined diffusion coefficients are obtained. The expressions for the transport coefficients can be reduced to the corresponding well-established expressions for plasmas in local thermodynamic equilibrium for the case in which the electron and heavy-species temperatures are equal.

General Expressions for Ellipsoidal-Valley Quantum Transport in Arbitrary Growth Direction: Non-Equilibrium Green's Function  

Science Journals Connector (OSTI)

A theoretical method for the calculation of quantum transport in an ellipsoidal valley is presented. This method is developed using a non-equilibrium Green's function framework. Importantly, it is instructive that kz is separated into two parts so that the wrong figure shape of the transmission coefficients does not exist. The L-electron effect on AlAs–GaAs–AlAs double barrier structures oriented in the [001], [111], and [110] growth directions is explored using the proposed method.

Nanotechnology for sustainable energy  

Science Journals Connector (OSTI)

Nanotechnology is generating a lot of attention these days and therefore building great expectations not only in the academic community but also among investors, the governments, and industry. Its unique capability to fabricate new structures at atomic scale has already produced novel materials and devices with great potential applications in a wide number of fields. Among them, significant breakthroughs are especially required in the energy sector that will allow us to maintain our increasing appetite for energy, which increases both with the number of people that join the developed economies and with our demand per capita. This needs to be done in a way that includes the environment in the wealth production equation as we gather more evidences of the human impact on the climate, biodiversity and quality of the air, water and soil. This review article does not cover in detail all the specific contributions from nanotechnology to the various sustainable energies, but in a broader way, it collects the most recent advances of nanotechnology to sustainable energy production, storage and use. For this review paper, solar, hydrogen and new generation batteries and supercapacitors are described as the most significant examples of the contributions of nanotechnology in the energy sector. The aim of this review article is to present some significant contributions from many research groups who are mainly unconnected and are working from different viewpoints, to find solutions to one of the great challenges of our time, i.e., the production and use of energy, without compromising our environment, from one of the most exciting and multidisciplinary fields, nanotechnology.

NON-EQUILIBRIUM DYNAMICS OF MANY-BODY QUANTUM SYSTEMS: FUNDAMENTALS AND NEW FRONTIER  

SciTech Connect

Rapid progress in nanotechnology and naofabrication techniques has ushered in a new era of quantum transport experiments. This has in turn heightened the interest in theoretical understanding of nonequilibrium dynamics of strongly correlated quantum systems. This project has advanced the frontiers of understanding in this area along several fronts. For example, we showed that under certain conditions, quantum impurities out of equilibrium can be reformulated in terms of an effective equilibrium theory; this makes it possible to use the gamut of tools available for quantum systems in equilibrium. On a different front, we demonstrated that the elastic power of a transmitted microwave photon in circuit QED systems can exhibit a many-body Kondo resonance. We also showed that under many circumstances, bipartite fluctuations of particle number provide an effective tool for studying many-body physics—particularly the entanglement properties of a many-body system. This implies that it should be possible to measure many-body entanglement in relatively simple and tractable quantum systems. In addition, we studied charge relaxation in quantum RC circuits with a large number of conducting channels, and elucidated its relation to Kondo models in various regimes. We also extended our earlier work on the dynamics of driven and dissipative quantum spin-boson impurity systems, deriving a new formalism that makes it possible to compute the full spin density matrix and spin-spin correlation functions beyond the weak coupling limit. Finally, we provided a comprehensive analysis of the nonequilibrium transport near a quantum phase transition in the case of a spinless dissipative resonant-level model. This project supported the research of two Ph.D. students and two postdoctoral researchers, whose training will allow them to further advance the field in coming years.

Nanotechnology, nanotoxicology, and neuroscience  

Science Journals Connector (OSTI)

Nanotechnology, which deals with features as small as a 1 billionth of a meter, began to enter into mainstream physical sciences and engineering some 20 years ago. Recent applications of nanoscience include the use of nanoscale materials in electronics, catalysis, and biomedical research. Among these applications, strong interest has been shown to biological processes such as blood coagulation control and multimodal bioimaging, which has brought about a new and exciting research field called nanobiotechnology. Biotechnology, which itself also dates back ?30 years, involves the manipulation of macroscopic biological systems such as cells and mice in order to understand why and how molecular level mechanisms affect specific biological functions, e.g., the role of APP (amyloid precursor protein) in Alzheimer's disease (AD). This review aims (1) to introduce key concepts and materials from nanotechnology to a non-physical sciences community; (2) to introduce several state-of-the-art examples of current nanotechnology that were either constructed for use in biological systems or that can, in time, be utilized for biomedical research; (3) to provide recent excerpts in nanotoxicology and multifunctional nanoparticle systems (MFNPSs); and (4) to propose areas in neuroscience that may benefit from research at the interface of neurobiologically important systems and nanostructured materials.

Nanomedicine, nanotechnology in medicine  

Science Journals Connector (OSTI)

Nanomedicine is a relatively new field of science and technology. It looks sometimes ill defined and interpretations of that term may vary, especially between Europe and the United States. By interacting with biological molecules, therefore at nanoscale, nanotechnology opens up a vast field of research and application. Interactions between artificial molecular assemblies or nanodevices and biomolecules can be understood both in the extracellular medium and inside the human cells. Operating at nanoscale allows to exploit physical properties different from those observed at microscale such as the volume/surface ratio. The investigated diagnostic applications can be considered for in vitro as well as for in vivo diagnosis. In vitro, the synthesised particles and manipulation or detection devices allow for the recognition, capture, and concentration of biomolecules. In vivo, the synthetic molecular assemblies are mainly designed as a contrast agent for imaging. A second area exhibiting a strong development is “nanodrugs” where nanoparticles are designed for targeted drug delivery. The use of such carriers improves the drug biodistribution, targeting active molecules to diseased tissues while protecting healthy tissue. A third area of application is regenerative medicine where nanotechnology allows developing biocompatible materials which support growth of cells used in cell therapy. The application of nanotechnology to medicine raises new issues because of new uses they allow, for instance: Is the power of these new diagnostics manageable by the medical profession? What means treating a patient without any clinical signs? Nanomedicine can contribute to the development of a personalised medicine both for diagnosis and therapy. There exists in many countries existing regulatory frameworks addressing the basic rules of safety and effectiveness of nanotechnology based medicine, whether molecular assemblies or medical devices. However, there is a need to clarify or to modify these regulations which mobilise many experts. France is a country where the medical development of nanotechnology is significant, like Germany, the United Kingdom or Spain, as regards the European Union. There is an active scientific community and industrial partners of all sizes, even if the technology transfer to industry is not as effective as in North America.

Influence of Penning effect on the plasma features in a non-equilibrium atmospheric pressure plasma jet  

SciTech Connect

Non-equilibrium atmospheric pressure plasma jet (APPJ) is a cold plasma source that promises various innovative applications. The influence of Penning effect on the formation, propagation, and other physical properties of the plasma bullets in APPJ remains a debatable topic. By using a 10?cm wide active electrode and a frequency of applied voltage down to 0.5?Hz, the Penning effect caused by preceding discharges can be excluded. It was found that the Penning effect originating in a preceding discharge helps build a conductive channel in the gas flow and provide seed electrons, thus the discharge can be maintained at a low voltage which in turn leads to a smaller propagation speed for the plasma bullet. Photographs from an intensified charge coupled device reveal that the annular structure of the plasma plume for He is irrelevant to the Penning ionization process arising from preceding discharges. By adding NH{sub 3} into Ar to introduce Penning effect, the originally filamentous discharge of Ar can display a rather extensive plasma plume in ambient as He. These results are helpful for the understanding of the behaviors of non-equilibrium APPJs generated under distinct conditions and for the design of plasma jet features, especially the spatial distribution and propagation speed, which are essential for application.

Quantum Physics and Nanotechnology  

E-Print Network (OSTI)

Experimental studies of infinite (unrestricted at least in one direction) quantum particle motion using probe nanotechnologies have revealed the necessity of revising previous concepts of their motion. Particularly, quantum particles transfer quantum motion nonlocality energy beside classical kinetic energy, in other words, they are in two different kinds of motion simultaneously. The quantum component of the motion energy may be quite considerable under certain circumstances. Some new effects were predicted and proved experimentally in terms of this phenomenon. A new prototype refrigerating device was tested, its principle of operation being based on the effect of transferring the quantum component of the motion energy.

Chapter 1 - What is Nanotechnology?  

Science Journals Connector (OSTI)

Abstract A nanodevice, or nanomachine, is defined as a nanoscale automaton, or at least one containing nanosized components. Direct nanotechnology refers to nanosized objects used directly in an application-a responsive nanoparticle used to deliver drugs to an internal target in the human body. Indirect nanotechnology refers to a device that contains a nanodevice, possibly along with other micro or macro components and systems. The definition of nanotechnology is “the design, characterization, production, and application of materials, devices and systems by controlling shape and size at the nanoscale.” In summary, nanotechnology has three aspects: (1) A universal fabrication procedure; (2) A particular way of conceiving, designing, and modeling materials, devices, and systems, including their fabrication; (3) The creation of novelty. The term “nanoscience” appears to be superfluous if it is used in the sense of “the science underlying nanotechnology.”

Nanotechnology: Small Matters  

SciTech Connect

The primary objective of this project was to engage members of the public in an active and balanced deliberative discussion about the social, ethical, legal, environmental, and policy issues arising from nanotechnologies. A second but equally important objective was to interest members of the public in learning more about science and technology and nanotechnology specifically by understanding how it will affect their lives. The objectives were met through a series of electronic and face-to-face citizen forums conducted in conjunction with three Fred Friendly Seminars being taped on the University of California, Berkeley campus in partnership with Lawrence Hall of Science (this forum was conducted in partnership with the St. Louis Science Center); the Boston Museum of Science in Boston, MA; and the State Museum of South Carolina in Columbia, South Carolina. The topical area for each forum paralleled the content of the Fred Friendly Seminars series being taped at each location, but specific topics/issues were drawn from the concerns and interests of the communities. The three topical areas included Environmental Impact (St. Louis), Privacy vs. Security (Boston), and Health and Enhancement (Columbia). The PI and project leader worked with the local science centers to identify stakeholder groups, such as academic, corporate and government scientists; environmental advocates; business leaders; science and technology journalists; and public policy makers within each community. Representatives from each group along with members of the general public were invited to participate in a series of on line and in person deliberations that were designed to provide basic information about the science, its potential benefits and risks, and avenues for public participation in policy formulation. On line resources were designed and managed by ScienceVIEW at Lawrence Hall of Science and Earth & Sky, Inc. The activities at each site were evaluated by Inverness Research Associates to assess whether they have achieved the objectives.

Non-equilibrium dynamics of an ultracold Bose gas under a multi-pulsed quantum quench in interaction  

E-Print Network (OSTI)

We investigate the nonequilibrium dynamical properties of a weakly-interacting Bose gas at zero temperature under the multi-pulsed quantum quench in interaction by calculating one-body, two-body correlation functions and Tan's contact of the model system. The multi-pulsed quench is represented as follows: first suddenly quenching the interatomic interaction from $g_{i}$ to $g_{f}$ at time $t=0$, holding time $t$, and then suddenly quenching interaction from $g_{f}$ back to $g_{i}$, holding the time $t$ sequence $n$ times. In particular, two typical kinds of quenching parameters are chosen, corresponding to $(g_{i}/g_{f}>1)$ and $(g_{i}/g_{f}powerful way of studying the non-equilibrium dynamics of many-body quantum system than the `one-off' quantum quench. Finally, we discuss the ultra-short-range properties of the two-body correlation function after the $n$th quenching, which can be used to probe the `Tan'scontact' in experiments. All our calculations can be tested in current cold atom experiments.

Cosmological QCD phase transition in steady non-equilibrium dissipative Ho\\v{r}ava-Lifshitz early universe  

E-Print Network (OSTI)

We study the phase transition from quark-gluon plasma to hadrons in the early universe in the context of non-equilibrium thermodynamics. According to the standard model of cosmology, a phase transition associated with chiral symmetry breaking after the electro-weak transition has occurred when the universe was about $1-10\\mu s$ old. We focus attention on such a phase transition in the presence of a viscous relativistic cosmological background fluid in the framework of non-detailed balance Ho\\v{r}ava-Lifshitz cosmology within an effective model of QCD. We consider a flat Friedmann-Robertson-Walker Universe filled with a non-causal and causal bulk viscous cosmological fluid respectively and investigate the effects of the running coupling constants of Ho\\v{r}ava-Lifshitz gravity, $\\lambda$, on the evolution of the physical quantities relevant to a description of the early universe, namely, the temperature $T$, scale factor $a$, deceleration parameter $q$ and dimensionless ratio of the bulk viscosity coefficient ...

In this note is touched upon an application of quantum information science (QIS) in nanotechnology area. The laws of quantum mechanics may be very important for nano-scale objects. A problem with simulating of quantum systems is well known and quantum computer was initially suggested by R. Feynman just as the way to overcome such difficulties. Mathematical methods developed in QIS also may be applied for description of nano-devices. Few illustrative examples are mentioned and they may be related with so-called fourth generation of nanotechnology products.

Nanotechnology: a slightly different history  

E-Print Network (OSTI)

Many introductory articles and books about nanotechnology have been written to disseminate this apparently new technology, which investigate and manipulates matter at dimension of a billionth of a meter. However, these texts show in general a common feature: there is very little about the origins of this multidisciplinary field. If anything is mentioned at all, a few dates, facts and characters are reinforced, which under the scrutiny of a careful historical digging do not sustain as really founding landmarks of the field. Nevertheless, in spite of these flaws, such historical narratives bring up important elements to understand and contextualize this human endeavor, as well as the corresponding dissemination among the public: would nanotechnology be a cultural imperative?

Chapter 1 - Nanoscience and Nanotechnology  

Science Journals Connector (OSTI)

Abstract Assuming that the reader is relatively new to the area of carbon nanotube reinforced composites, this chapter aims to create a solid background in the topics of nanoscience and nanotechnology (N&N). We start with an introduction to the nanoscale, from basic themes, such as the importance of size, and why the properties of materials change at the nanoscale. The concepts of N&N are presented from the starting point: the Feynman’s lecture in 1959. The different types of nanotechnology are discussed. The history of nano shows us that nanotechnology was, somehow, already been used in the ancient world as demonstrated by great examples as the Lycurgus cup and stained glass windows. The “nano world” has inspired many applications that make use of the new features and phenomena observed at the nanoscale. We discuss some of the existing and envisioned applications in many areas, including medicine, food, electronics, energy, air pollution, space, and even sports. Finally, we take a look to the future and realize that although scientists are able to manipulate materials at the atomic scale, atom by atom, there is still much to be done, i.e., There is Plenty of Room at the Bottom!

Enhanced heat transfer through filler-polymer interface by surface-coupling agent in heat-dissipation material: A non-equilibrium molecular dynamics study  

SciTech Connect

Developing a composite material of polymers and micrometer-sized fillers with higher heat conductance is crucial to realize modular packaging of electronic components at higher densities. Enhancement mechanisms of the heat conductance of the polymer-filler interfaces by adding the surface-coupling agent in such a polymer composite material are investigated through the non-equilibrium molecular dynamics (MD) simulation. A simulation system is composed of ?-alumina as the filler, bisphenol-A epoxy molecules as the polymers, and model molecules for the surface-coupling agent. The inter-atomic potential between the ?-alumina and surface-coupling molecule, which is essential in the present MD simulation, is constructed to reproduce the calculated energies with the electronic density-functional theory. Through the non-equilibrium MD simulation runs, we find that the thermal resistance at the interface decreases significantly by increasing either number or lengths of the surface-coupling molecules and that the effective thermal conductivity of the system approaches to the theoretical value corresponding to zero thermal-resistance at the interface. Detailed analyses about the atomic configurations and local temperatures around the interface are performed to identify heat-transfer routes through the interface.

Chapter 3 - Safety and Ethics of Nanotechnology  

Science Journals Connector (OSTI)

Abstract Nanotechnology is one of the ways of improving many properties of materials, including physical, chemical, physicochemical, and biological, which can be useful for various applications in biomedical, textile, aerospace, manufacturing, cosmetics, oil, defense, agricultural, and electronics industries. Nevertheless, nanotechnology products, or nanomaterials (e.g., nanotubes, nanoparticles, nanofibers, nanowires, nanocomposites, and nanofilms), can be unsafe to human health because of the way they are manipulated and treated at near atomic scale. Since these nanomaterials are produced with mainly new manufacturing techniques and have various sizes, shapes, and surface energies, they may also create some uncertainties because of the lack of specific rules and regulations governing their manufacture and manipulation. This study provides a detailed report on the safety and ethics of nanotechnology and related ethical, social, philosophical, environmental, biological, and other legal issues. The information provided here can be very useful for training and protecting scientists, engineers, students, policymakers, and regulators working in the nanotechnology and related technologies.

I then consider coarse-grained models of DNA, mesoscale descriptions that have the potential to provide great insight into the operation of DNA nanotechnology if they are well designed. In particular, I discuss a number of nanotechnological systems that have been studied with oxDNA, a recently developed coarse-grained model, highlighting the subtle interplay of kinetic, thermodynamic and mechanical factors that can determine behaviour. Finally, new results highlighting the importance of mechanical tension in the operation of a two-footed walker are presented, demonstrating that recovery from an unintended `overstepp...

Enabling individualized therapy through nanotechnology  

Science Journals Connector (OSTI)

Individualized medicine is the healthcare strategy that rebukes the idiomatic dogma of ‘losing sight of the forest for the trees’. We are entering a new era of healthcare where it is no longer acceptable to develop and market a drug that is effective for only 80% of the patient population. The emergence of “-omic” technologies (e.g. genomics, transcriptomics, proteomics, metabolomics) and advances in systems biology are magnifying the deficiencies of standardized therapy, which often provide little treatment latitude for accommodating patient physiologic idiosyncrasies. A personalized approach to medicine is not a novel concept. Ever since the scientific community began unraveling the mysteries of the genome, the promise of discarding generic treatment regimens in favor of patient-specific therapies became more feasible and realistic. One of the major scientific impediments of this movement towards personalized medicine has been the need for technological enablement. Nanotechnology is projected to play a critical role in patient-specific therapy; however, this transition will depend heavily upon the evolutionary development of a systems biology approach to clinical medicine based upon “-omic” technology analysis and integration. This manuscript provides a forward looking assessment of the promise of nanomedicine as it pertains to individualized medicine and establishes a technology “snapshot” of the current state of nano-based products over a vast array of clinical indications and range of patient specificity. Other issues such as market driven hurdles and regulatory compliance reform are anticipated to “self-correct” in accordance to scientific advancement and healthcare demand. These peripheral, non-scientific concerns are not addressed at length in this manuscript; however they do exist, and their impact to the paradigm shifting healthcare transformation towards individualized medicine will be critical for its success.

Nanotechnology in the market: promises and realities  

Science Journals Connector (OSTI)

Nanotechnology is one of the key research areas of the 21st century affecting several different disciplines and industries. Amongst leading scientists there is growing awareness about the tremendous impact this field will have on society and the economy. It is forecast to become possibly even more important than for example the invention of the steam engine or the discovery of penicillin. However, the vast amount of research projects associated with nanotechnology makes it increasingly difficult to distinguish between promises for future products and real applications that are already in the market. The situation is even more complicated by the fact that nano is not a protected and well-defined term. Therefore it is also misused for marketing purposes of non-nano products. This paper is intended to contribute to a clearer picture about scientific developments and subsequently commercialised nanotechnological applications. In order to deliver a cohesive review, the focus was laid on six nanotechnology fields relevant for end-consumers (pharmaceutical, cosmetic, food, textile, automotive and construction). For the database search, a working definition was devised to discriminate nano from non-nano applications. In the present paper both scientific background information and market data about the nano-enabled products are presented, to reach the goal of combining economic analyses and chemical insights into nanotechnology. The results show that some commercialised technologies have several application fields, whereas others are only found in one market. Furthermore, it was demonstrated that regarding turnovers the pharmaceutical sector is currently the most important of the six considered nanotechnology markets, but all of them are expected to grow significantly in the future.

Spin-polarization and spin-dependent logic gates in a double quantum ring based on Rashba spin-orbit effect: Non-equilibrium Green's function approach  

SciTech Connect

Spin-dependent electron transport in an open double quantum ring, when each ring is made up of four quantum dots and threaded by a magnetic flux, is studied. Two independent and tunable gate voltages are applied to induce Rashba spin-orbit effect in the quantum rings. Using non-equilibrium Green's function formalism, we study the effects of electron-electron interaction on spin-dependent electron transport and show that although the electron-electron interaction induces an energy gap, it has no considerable effect when the bias voltage is sufficiently high. We also show that the double quantum ring can operate as a spin-filter for both spin up and spin down electrons. The spin-polarization of transmitted electrons can be tuned from ?1 (pure spin-down current) to +1 (pure spin-up current) by changing the magnetic flux and/or the gates voltage. Also, the double quantum ring can act as AND and NOR gates when the system parameters such as Rashba coefficient are properly adjusted.

Nanomedicine is exploring how to use carbon buckyballs, dendrimers and other cleverly engineered nanoparticles in novel drugs to combat viruses, bacteria, cancer and delivery of drugs. Medical nanorobots will be of the size of a microbe, capable of self-replication, containing onboard sensors, computers, manipulators, pumps, pressure tanks and power supplies. Building such sophisticated molecular machine systems will require molecular manufacturing to using massively parallel assembly lines in nanofactories.

More generally, the walker illustrates the possibility of biasing strand-displacement processes to affect the overall rate.

Control Banding and Nanotechnology Synergist  

SciTech Connect

The average Industrial Hygienist (IH) loves a challenge, right? Okay, well here is one with more than a few twists. We start by going through the basics of a risk assessment. You have some chemical agents, a few workers, and the makings of your basic exposure characterization. However, you have no occupational exposure limit (OEL), essentially no toxicological basis, and no epidemiology. Now the real handicap is that you cannot use sampling pumps, cassettes, tubes, or any of the media in your toolbox, and the whole concept of mass-to-dose is out the window, even at high exposure levels. Of course, by the title, you knew we were talking about nanomaterials (NM). However, we wonder how many IHs know that this topic takes everything you know about your profession and turns it upside down. It takes the very foundations that you worked so hard in college and in the field to master and pulls it out from underneath you. It even takes the gold standard of our profession, the quantitative science of exposure assessment, and makes it look pretty darn rusty. Now with NM there is the potential to get some aspect of quantitative measurements, but the instruments are generally very expensive and getting an appropriate workplace personal exposure measurement can be very difficult if not impossible. The potential for workers getting exposures, however, is very real, as evidenced by a recent publication reporting worker exposures to polyacrylate nanoparticles in a Chinese factory (Song et al. 2009). With something this complex and challenging, how does a concept as simple as Control Banding (CB) save the day? Although many IHs have heard of CB, most of their knowledge comes from its application in the COSHH Essentials toolkit. While there is conflicting published research on COSHH Essentials and its value for risk assessments, almost all of the experts agree that it can be useful when no OELs are available (Zalk and Nelson 2008). It is this aspect of CB, its utility with uncertainty, that attracted international NM experts to recommend this qualitative risk assessment approach for NM. However, since their CB recommendation was only in theory, we took on the challenge of developing a working toolkit, the CB Nanotool (see Zalk et al. 2009 and Paik et al. 2008), as a means to perform a risk assessment and protect researchers at the Lawrence Livermore National Laboratory. While it's been acknowledged that engineered NM have potentially endless benefits for society, it became clear to us that the very properties that make nanotechnology so useful to industry could also make them dangerous to humans and the environment. Among the uncertainties and unknowns with NM are: the contribution of their physical structure to their toxicity, significant differences in their deposition and clearance in the lungs when compared to their parent material (PM), a lack of agreement on the appropriate indices for exposure to NM, and very little background information on exposure scenarios or populations at risk. Part of this lack of background information can be traced to the lack of risk assessments historically performed in the industry, with a recent survey indicating that 65% of companies working with NM are not doing any kind of NM-specific risk assessment as they focus on traditional PM methods for IH (Helland et al. 2009). The good news is that the amount of peer-reviewed publications that address environmental, health and safety aspects of NM has been increasing over the last few years; however, the percentage of these that address practical methods to reduce exposure and protect workers is orders of magnitude lower. Our intent in developing the CB Nanotool was to create a simplified approach that would protect workers while unraveling the mysteries of NM for experts and non-experts alike. Since such a large part of the toxicological effects of both the physical and chemical properties of NM were unknown, not to mention changing logarithmically as new NM research continues growing, we needed to account for this lack of information as part of the CB Nano

Multidisciplinary Cognitive Content of Nanoscience and Nanotechnology  

E-Print Network (OSTI)

This article examines the cognitive evolution and disciplinary diversity of nanotechnology as expressed through the terminology used in titles of nano journal articles. The analysis is based on the NanoBank bibliographic database of 287,106 nano articles published between 1981 and 2004. We perform multifaceted analyses of title words, focusing on 100 most frequent terms. Hierarchical clustering of title terms reveals three distinct time periods of cognitive development of nano research: formative (1981-1990), early (1991-1998), and current (after 1998). Early period is characterized by the introduction of thin film deposition techniques, while the current period is characterized by the increased focus on carbon nanotube and nanoparticle research. We introduce a method to identify disciplinary components of nanotechnology. It shows that the nano research is being carried out in a number of diverse parent disciplines. Currently only 5% of articles are published in dedicated nano-only journals. We find that some...

Nanotechnology: a successive industrial revolution of Schumpeter's long wave theory  

Science Journals Connector (OSTI)

This paper is concerned with the strategies on research management and technology policies of nanotechnology. Nanotechnology is now a science and technology (S&T) priority area for many Asian countries with governments making efforts to put the results of nanotechnology development to commercialisation. The national policy for nanotechnology is to change the existing technology system and bring about an industrial revolution (the nanorevolution). Under the pressure of competition, the key to success lies in how each country can find the right application on which to focus in order to survive through international competition. This paper reviews nanotechnology research activities in some Asian countries exhibiting an enthusiastic approach in undertaking nanotechnology initiatives â?? Thailand, Malaysia, Singapore, China, South Korea, Taiwan, and Japan. The paper finally recommends policy implications to encourage national innovativeness and effective commercialisation.

Nanoscience to nanotechnology to manufacturing transition  

Science Journals Connector (OSTI)

The primary focus of this review is on the transition of nanoscience to nanotechnology to manufacturing, specifically related to nanostructuring of materials for next-generation systems having superior performance. We start with the discussion of intrinsic advantages of nanoscale materials and systematic approach for transition into systems. As the feature (grain) size of solid-state materials decreases, the defect content reduces and below a critical size material can be defect-free. Since these critical sizes for most materials lie in 5-100 nm, there is a fundamental advantage and an unprecedented opportunity to realise the property of a perfect material. Along with this opportunity, there is a major challenge with respect to the large fraction of atoms at the interfaces, which must be engineered to realise the advantages of nanotechnology-based systems. We specifically address nanosystems based upon nanodots and nanolayered materials synthesised by thin film deposition techniques, where recurring themes include nanostructuring of materials to improve performance; thin film epitaxy across the misfit scale for orientation controls; control of defects, interfaces and strains; and integration of nanoscale devices with (100) silicon based microelectronics and nanoelectronics. The systems of interest are based upon strong novel structural materials, nanomagnetics for information storage, nanostructured or Nano Pocket LEDs, variety of smart structures based upon vanadium oxide and novel perovskites integrated with Si(100), and nanotechnology based solutions to enhance fuel efficiency and reduce environmental pollution.

Technology roadmapping through intelligence analysis: case of nanotechnology  

Science Journals Connector (OSTI)

Nanotechnology is predicted to create the Sixth Kondratieff period following the 'age of information'. It represents a new revolutionary approach in fundamental research moving from a macrocentric to nanocentric system. Nanotechnology is expected to stimulate one trillion dollars of production involving about two million workers in the next ten to 15 years. More than 40 countries now have specific nanotechnology research funding programs with the common goal of finding greater uses for the emerging technologies and enacting measures to encourage commercialisation. This study uses text mining to uncover trends in nanotechnology and changes in nanotechnology programs and applications since the first distribution of the National Nanotechnology Initiative (NNI) funds in 2001. Top keywords in current nanotechnology research will be analysed to provide insight into the translation of government funding invested in applied research programs to resulting publications and patents. Future work will extend this text mining model to develop an emerging technology roadmap to uncover commercialisation opportunities by using R&D project funding at this lowest level to roll up to the technology and product dimensions.

Nanotechnology in water treatment: an emerging trend  

Science Journals Connector (OSTI)

With advances in nanotechnology, different types of nanomaterial are emerging for applications in water purification and water treatment devices owing to their effectiveness against both chemical and biological contaminants. This paper discusses the application of nanoscale materials that are being evaluated or developed as functional materials for water treatment, e.g. nanomembranes (nanocomposite RO and NF and carbon nanotubes), metal nanoparticles, nanoadsorbents, magnetic nanoparticles, bioactive nanoparticles, carbonaceous nanomaterials, zeolites, dendrimers and nanofibres. Nanomaterials are intrinsically better in terms of performance than other substances used in water treatment because of their high surface area (surface/volume ratio). Owing to these characteristics, these may be used in future at large scale for water purification.

Chapter 14 - The Geography of Nanotechnology  

Science Journals Connector (OSTI)

Abstract This chapter explores some of those differences in activity-nanotechnology in a global manufacturing context. According to the Civilization Index (CI), the countries of the world can be grouped into four categories: (1) high per-capita income, high level of scientific activity, (2) low per-capita income, high level of scientific activity, (3) high per-capita income, low level of scientific activity, and (4) low per-capita income, low level of scientific activity. Category I comprises the wealthiest countries of the world. Category II mostly comprises countries of the former Soviet Union. Category III comprises countries with a lower level of civilization that have acquired vast riches in recent decades through the export of raw materials found within their territories, notably mineral oil. Category IV comprises countries with a lower level of civilization that might require centuries of development before reaching the attainments of Category I.

Issues surrounding the wide spectrum of (perceived) risks and possible benefits associated with the rapid advance of modern nanotechnology are deliberated. These include the current realities of nanotechnological hazards, their impact vis-a-vis perceived nanotech-risks and perceived nanotech-benefits, and the consequent repercussions on the public and society. It is argued that both the risks and the benefits of nanoscientific advances must be properly communicated if the public is to support this emerging technology.

All three of our current IFAs (p. 10) now have a full head of steam, and nearly 30% of our current user projects map in some meaningful way to one of these IFAs. As part of our redoubled effort to increase our industrial user base, we are also looking to leverage these IFAs to build a stronger link to and spur recruitment within our industrial user community. We believe that the IFAs are a natural community-building tool with an intrinsic value proposition for industry; an R&D pipeline that can lead to more mature, more commercially well-positioned technologies. Finally, as nanoscience and nanotechnology are maturing, we as a research community are beginning to see our efforts extend in many exciting new directions. Our focus on nanoscience integration positions us very well to capitalize on new opportunities including the emerging Mesoscale Initiative within the DOE Office of Science. Many aspects of mesoscale science are embodied in the integration of nanoscale building blocks. We are equally proud of our continuing strong performance in support of our user program. We have fully transitioned to our new user proposal database providing enhanced convenience and flexibility for proposal submission and review. In our two regular proposal calls this year we received a total of 225 proposals, an increase of 10% over our 2010 performance. Our official count on number of users for the period remains at {approx}350 and continues to reflect full engagement of our scientific staff. We are also seeing a steady increase in our industrial user base, with the number of industrial proposals (including Rapid Access proposals) doubling in 2011. We attribute this in part of our outreach efforts including our focused industrial session in each of our past two annual User Conferences. The Center for Integrated Nanotechnologies (CINT) is a Department of Energy/Office of Science Nanoscale Science Research Center (NSRC) operating as a national user facility devoted to establishing the scientific principles that govern the design, performance, and integration of nanoscale materials. Jointly operated by Los Alamos and Sandia National Laboratories, CINT explores the continuum from scientific discovery to use-inspired research, with a focus on the integration of nanoscale materials and structures to achieve new properties and performance and their incorporation into the micro- and macro worlds. Through its Core Facility at Sandia National Laboratories and its Gateway Facility at Los Alamos National Laboratory, CINT provides open access to tools and expertise needed to explore the continuum from scientific discovery to the integration of nanostructures into the micro- and macro worlds. In its overall operations, CINT strives to achieve the following goals common to all Nanoscale Science Research Centers: (1) Conduct forefront research in nanoscale science; (2) Operate as a user facility for scientific research; (3) Provide user access to the relevant BES-supported expertise and capabilities at the host national laboratory; and (4) Leverage other relevant national laboratory capabilities to enhance scientific opportunities for the nanoscience user community. These additional goals are specific to the unique CINT mission: (5) Establish and lead a scientific community dedicated to solving nanoscale science integration challenges; and (6) Create a single user facility program that combines expertise and facilities at both Los Alamos and Sandia National Laboratories.

16 - Nanotechnology for domestic water purification  

Science Journals Connector (OSTI)

Abstract: Water, a nonsubstitutional natural resource, is best described by Leonardo Da Vinci as ‘the vehicle of nature’ (‘vetturale di natura’). This is the single most essential commodity responsible for the existence and sustenance of life on the planet earth. It is not at all an exaggeration to state that water is primarily responsible for the restoration of health, environment and prosperiy of human civilization. Unfortunately, this most precious natural resource is becoming increasingly scarce day by day. Water scarcity is among the main problems facing many societies around the world in the twenty-first century. Water use has been growing at more than twice the rate of population increase in the last century. According to a report from the United Nations, by 2025, 1800 million people will be living in countries or regions with absolute water scarcity, and two-thirds of the world’s population could be under stress conditions. As emphasized in one of the UN’s Millenium Development Goals (MDGs), water scarcity calls for strengthened international cooperation in the fields of technologies for enhanced water productivity. Recent years have witnessed impressive breakthroughs towards application of nanostructured materials such as carbon nanotubes (CNTs), metal/metal-oxide nanoparticles, zeolites, and dendrimers in the field of water purification. The present chapter aims to give an overview of the developments in the application of nanotechnology in water treatment, with a special emphasis on domestic water purification. The focus is oriented to the fact that the ultimate practical realization of this new technology is based on the assessment of the risks as well as benefits posed by nanostructured materials. The challenges involved in producing a well-defined integrated nano-based water purification device are discussed.

"Nanotechnology Enabled Advanced Industrial Heat Transfer Fluids"  

SciTech Connect

ABSTRACT Nanotechnology Enabled Advanced industrial Heat Transfer Fluids” Improving the efficiency of Industrial Heat Exchangers offers a great opportunity to improve overall process efficiencies in diverse industries such as pharmaceutical, materials manufacturing and food processing. The higher efficiencies can come in part from improved heat transfer during both cooling and heating of the material being processed. Additionally, there is great interest in enhancing the performance and reducing the weight of heat exchangers used in automotives in order to increase fuel efficiency. The goal of the Phase I program was to develop nanoparticle containing heat transfer fluids (e.g., antifreeze, water, silicone and hydrocarbon-based oils) that are used in transportation and in the chemical industry for heating, cooling and recovering waste heat. Much work has been done to date at investigating the potential use of nanoparticle-enhanced thermal fluids to improve heat transfer in heat exchangers. In most cases the effect in a commercial heat transfer fluid has been marginal at best. In the Phase I work, we demonstrated that the thermal conductivity, and hence heat transfer, of a fluid containing nanoparticles can be dramatically increased when subjected to an external influence. The increase in thermal conductivity was significantly larger than what is predicted by commonly used thermal models for two-phase materials. Additionally, the surface of the nanoparticles was engineered so as to have a minimal influence on the viscosity of the fluid. As a result, a nanoparticle-laden fluid was successfully developed that can lead to enhanced heat transfer in both industrial and automotive heat exchangers

Chapter 1 - Nanotechnology and the Future of Dentistry  

Science Journals Connector (OSTI)

Publisher Summary This chapter provides an overview of nanotechnology and its future applications in dentistry. In the field of medicine, nanotechnology has been applied in diagnosis, prevention, and treatment of diseases. Nanotechnology offers considerable scope in dentistry to improve dental treatment, care, and prevention of oral diseases. Nanotechnology has been in dentistry for tooth sealants and fillers that use nanosized particles to improve their strength, luster, and resist wear. Antimicrobial nanoparticles in restorative composite materials are used to prevent dental caries. Silver particles as antibacterial agents when used in fillers and toothpastes can retard bacterial growth and reduce tooth decay. It is envisaged that in the longer term biomimetic approaches and nanotechnology will be used to repair and rebuild damaged enamel. In near future, nanomaterials will be used far more widely and will yield superior properties and combined with biotechnology, laser and digital guided surgery will provide excellent dental care. Smarter preventive measures and earlier interventions to avert craniofacial disorders using nanodiagnostics seems a reality. Nanotechnology research will pave the way for development of tools which would allow clinicians to diagnose and treat oral malignancies at their earliest stage. Nanotechnology is a term that is used to describe the science and technology related to the control and manipulation of matter and devices on a scale less than 100nm in dimension. It involves a multidisciplinary approach involving fields such as applied physics, materials science, chemistry, biology, biomedical engineering, surface science, electrical engineering, and robotics. At the nanoscale level, the properties of matter are dictated and there are fewer boundaries between scientific disciplines. Generally, two main approaches have been used in nanotechnology. These are known as the “bottom-up” and “top-down” approaches. The former involves building up from atoms into molecules to assemble nanostructures, materials, and devices. The second approach involves making structures and devices from larger entities without specific control at the atomic level. Progress in both approaches has been accelerated in recent years with the development and application of highly sensitive instruments. For example, atomic force microscopy (AFM), scanning tunnelling microscope (STM), electron beam lithography, molecular beam epitaxy, and so on have become available to push forward developments in this exciting new field. These instruments allow observation and manipulation of novel nanostructures. By investigating and understanding the functionality of materials at the micro/nanoscale level, the scientific community is working towards finding new techniques to achieve maximum functional output from these materials with minimum energy and resource input. Extensive research is being done worldwide to understand the advantages and scientific limitations of nanotechnology and its applications in a wide range of disciplines from material science, biomedical research to space research. In the field of medicine, nanotechnology has been extensively applied in nanoparticle-based drug delivery, nanoscale diagnostic tools, tissue engineering, and biosensors. In the field of dentistry, there have been numerous research work done over the past few decades exploring the applications of nanotechnology in dental biomaterials, dental implantology, dental instruments, nanoparticles/scaffolds for bone regeneration around dental implants and maxillofacial region, and nanodiagnostic tools to diagnose oral pathology. In this chapter, the applications of nanotechnology in dentistry have been outlined and are described in the subsequent chapters of this book.

Nanotechnology in the regulation of stem cell behavior  

Science Journals Connector (OSTI)

Stem cells are known for their potential to repair damaged tissues. The adhesion, growth and differentiation of stem cells are likely controlled by the surrounding microenvironment which contains both chemical and physical cues. Physical cues in the microenvironment, for example, nanotopography, were shown to play important roles in stem cell fate decisions. Thus, controlling stem cell behavior by nanoscale topography has become an important issue in stem cell biology. Nanotechnology has emerged as a new exciting field and research from this field has greatly advanced. Nanotechnology allows the manipulation of sophisticated surfaces/scaffolds which can mimic the cellular environment for regulating cellular behaviors. Thus, we summarize recent studies on nanotechnology with applications to stem cell biology, including the regulation of stem cell adhesion, growth, differentiation, tracking and imaging. Understanding the interactions of nanomaterials with stem cells may provide the knowledge to apply to cell–scaffold combinations in tissue engineering and regenerative medicine.

Langmuir probe measurements in a time-fluctuating-highly ionized non-equilibrium cutting arc: Analysis of the electron retarding part of the time-averaged current-voltage characteristic of the probe  

SciTech Connect

This work describes the application of Langmuir probe diagnostics to the measurement of the electron temperature in a time-fluctuating-highly ionized, non-equilibrium cutting arc. The electron retarding part of the time-averaged current-voltage characteristic of the probe was analysed, assuming that the standard exponential expression describing the electron current to the probe in collision-free plasmas can be applied under the investigated conditions. A procedure is described which allows the determination of the errors introduced in time-averaged probe data due to small-amplitude plasma fluctuations. It was found that the experimental points can be gathered into two well defined groups allowing defining two quite different averaged electron temperature values. In the low-current region the averaged characteristic was not significantly disturbed by the fluctuations and can reliably be used to obtain the actual value of the averaged electron temperature. In particular, an averaged electron temperature of 0.98 ± 0.07 eV (= 11400 ± 800 K) was found for the central core of the arc (30 A) at 3.5 mm downstream from the nozzle exit. This average included not only a time-average over the time fluctuations but also a spatial-average along the probe collecting length. The fitting of the high-current region of the characteristic using such electron temperature value together with the corrections given by the fluctuation analysis showed a relevant departure of local thermal equilibrium in the arc core.

Non-equilibrium thermodynamics of gravitational screens  

E-Print Network (OSTI)

We study the Einstein gravity equations projected on a timelike surface, which represents the time evolution of what we call a gravitational screen. We show that such a screen possesses a surface tension and an internal energy, and that the Einstein equations reduce to the thermodynamic equations of a viscous bubble. We also provide a complete dictionary between gravitational and thermodynamical variables. In the non-viscous cases there are three thermodynamic equations which characterise a bubble dynamics: These are the first law, the Marangoni flow equation and the Young-Laplace equation. In all three equations the surface tension plays a central role: In the first law it appears as a work term per unit area, in the Marangoni flow its gradient drives a force, and in the Young-Laplace equation it contributes to a pressure proportional to the surface curvature. The gravity equations appear as a natural generalization of these bubble equations when the bubble itself is viscous and dynamical. In particular, it shows that the mechanism of entropy production for the viscous bubble is mapped onto the production of gravitational waves. We also review the relationship between surface tension and temperature, and discuss the usual black-hole thermodynamics from this point of view.

Chapter 30 - Applications of Nanotechnology for Regenerative Medicine  

Science Journals Connector (OSTI)

Publisher Summary This chapter examines the impact of nanotechnology on regenerative medicine related to cellular therapies and biomaterial control, which play an important role for implant design and tissue engineering. Cellular therapies for regenerative medicine would benefit from nanotechnology since tracking of implanted cells would provide the means to better evaluate the viability of engineered tissues and help in understanding the biodistribution and migration pathways of transplanted cells. Nanotechnology would also allow better and more intelligent control of the bioactive factors, which can influence cellular therapies. Biomaterials play an important role in regenerative medicine because they make up a large component of implants and tissue scaffolds. Biocompatible scaffolds could provide temporary structural support guiding cell growth, assist the transportation of essential nutrients, and facilitate the formation of functional tissues and organs. Increasing evidence shows that the nature of the biomaterial greatly affects long-term success of biomedical implants and short-term wound healing response. Substrate features such as the chemical composition and surface morphology affect the viability, adhesion, morphology, and motility of cells. Therefore, controlling the three-dimensional structure and surface composition of a biomaterial is important to promoting normal tissue growth or minimizing foreign body response. The unique properties of nanomaterials and nanostructures could be particularly useful in controlling intrinsic stem cell signals and in dissecting the mechanisms underlying embryonic and adult stem cell behavior.

Nanotechnology in reproductive medicine: Emerging applications of nanomaterials  

Science Journals Connector (OSTI)

Abstract In the last decade, nanotechnology has been extensively introduced for biomedical applications, including bio-detection, drug delivery and diagnostic imaging, particularly in the field of cancer diagnostics and treatment. However, there is a growing trend towards the expansion of nanobiotechnological tools in a number of non-cancer applications. In this review, we discuss the emerging uses of nanotechnology in reproductive medicine and reproductive biology. For the first time, we summarise the available evidence regarding the use of nanomaterials as experimental tools for the detection and treatment of malignant and benign reproductive conditions. We also present an overview of potential applications for nanomaterials in reproductive biology, discuss the benefits and concerns associated with their use in a highly delicate system of reproductive tissues and gametes, and address the feasibility of this innovative and potentially controversial approach in the clinical setting and for investigative research into the mechanisms underlying reproductive diseases. From the Clinical Editor This unique review paper focuses on the emerging use of nanotechnology in reproductive medicine and reproductive biology, highlighting the role of nanomaterials in the detection and treatment of various reproductive conditions, keeping in mind the benefits and potential concerns associated with nanomaterial use in the delicate system of reproductive tissue and gametes.

'Mind the gap': science and ethics in nanotechnology  

Science Journals Connector (OSTI)

Nanotechnology (NT) is a rapidly progressing field. Advances will have a tremendous impact on fields such as materials, electronics, and medicine. A thorough review of the current literature, governmental funding, and policy documents was undertaken. Despite the potential impact of NT, and the abundance of funds, our research revealed that there is a paucity of serious, published research into the ethical, legal, and social implications of NT. As the science leaps ahead, the ethics lags behind. There is danger of derailing NT if the study of ethical, legal, and social implications does not catch up with the speed of scientific development.

Nanotechnology and Quasicrystals: From self assembly to photonic applications  

E-Print Network (OSTI)

After providing a concise overview on quasicrystals and their discovery more than a quarter of a century ago, I consider the unexpected interplay between nanotechnology and quasiperiodic crystals. Of particular relevance are efforts to fabricate artificial functional micro- or nanostructures, as well as efforts to control the self-assembly of nanostructures, where current knowledge about the possibility of having long-range order without periodicity can provide significant advantages. I discuss examples of systems ranging from artificial metamaterials for photonic applications, through self-assembled soft matter, to surface waves and optically-induced nonlinear photonic quasicrystals.

Nanotechnology the science of building structures by the manipulation and placement of individual atoms and molecules is fast becoming an important segment to the next technological transformation, as many scientists, futurists and researchers agree. Nanotechnology, as a rapidly progressing field and coupled with the advances of the past fifty years, will have a tremendous impact on fields such as materials, electronics and medicine towards 2025. Rather than providing a detailed approach, this article will identify promising nanotechnology movements and their potentially significant effects on the world, including those with ethical implications. It will focus largely on one aspect of nanotechnology, namely molecular assembly, which could in principle enable manufacturing and production through the bottom-up assembly of consumer goods and products, one atom at a time.

Applications of nanotechnology in renewable energies—A comprehensive overview and understanding  

Science Journals Connector (OSTI)

Abstract One of the great technological challenges in 21st century is the development of renewable energy technologies due to serious problems related with the production and use of energy. A new promising area of research grows rapidly which is called Nanotechnologies are considered nowadays one of the most recommended choices to solve this problem. This review aims to introduce several significant applications of nanotechnology in renewable energy systems. Papers reviewed including theoretical and experimental works related with nanotechnology applications in solar, hydrogen, wind, biomass, geothermal and tidal energies. A lot of literature are reviewed and summarized carefully in a useful tables to give a panoramic overview about the role of nanotechnology in improving the various sources of renewable energies. We think that this paper can be considered as an important bridge between nanotechnology and all available kinds of renewable energies. From the other side, further researches are required to study the effect of nanotechnology to enhance the renewable energy industry especially in geothermal, wind and tidal energies, since the available papers in these fields are limited.

Chapter 9 - Nanotechnology-Based Membranes for Water Purification  

Science Journals Connector (OSTI)

Herein we present a critical review of nanotechnology-enabled materials touted as low-energy replacements for conventional reverse osmosis (RO) membranes in desalination and water reuse applications. Zeolite coatings promise a highly selective material that have the chemical, thermal, and mechanical stabilities of conventional ceramic membranes. Nanocomposite membranes exhibit up to three times higher permeability than current commercial polymeric membranes, with no change in salt rejection, and can be fabricated with antimicrobial and photoreactive functionalities. Biomimetic membranes can produce highly selective membranes potentially useful in both forward osmosis and RO applications. Aquaporin (AQP)-based lipid bilayer vesicles exhibit nearly 100 times higher water permeability than commercial membranes with near perfect salt rejection. Carbon nanotube (CNT)- and graphene-based membranes (theoretically) exhibit acceptable salt rejections with water permeabilities between 5 and 1000 times higher than commercial membranes. Self-assembled block copolymer membranes represent a fully polymeric approach to forming highly selective structures reminiscent of AQP- or CNT-based materials.

TRADITIONAL METALLURGY, NANOTECHNOLOGIES AND STRUCTURAL MATERIALS: A SORBY AWARD LECTURE  

SciTech Connect

Traditional metallurgical processes are among the many ''old fashion'' practices that use nanoparticles to control the behavior of materials. Many of these practices were developed long before microscopy could resolve nanoscale features, yet the practitioners learned to manipulate and control microstructural elements that they could neither see nor identify. Furthermore, these early practitioners used that control to modify microstructures and develop desired material properties. Centuries old colored glass, ancient high strength steels and medieval organ pipes derived many of their desirable features through control of nanoparticles in their microstructures. Henry Sorby was among the first to recognize that the properties of rocks, minerals, metals and organic materials were controlled by microstructure. However, Mr. Sorby was accused of the folly of trying to study mountains with a microscope. Although he could not resolve nanoscale microstructural features, Mr. Sorby's observations revolutionized the study of materials. The importance of nanoscale microstructural elements should be emphasized, however, because the present foundation for structural materials was built by manipulating those features. That foundation currently supports several multibillion dollar industries but is not generally considered when the nanomaterials revolution is discussed. This lecture demonstrates that using nanotechnologies to control the behavior of metallic materials is almost as old as the practice of metallurgy and that many of the emergent nanomaterials technologists are walking along pathways previously paved by traditional metallurgists.

Nanotechnology as a Field of Science: Its Delineation in terms of Journals and Patents  

E-Print Network (OSTI)

The Journal Citation Reports of the Science Citation Index 2004 were used to delineate a core set of nanotechnology journals and a nanotechnology-relevant set. In comparison with 2003, the core set has grown and the relevant set has decreased. This suggests a higher degree of codification in the field of nanotechnology: the field has become more focused in terms of citation practices. Using the citing patterns among journals at the aggregate level, a core group of ten nanotechnology journals in the vector space can be delineated on the criterion of betweenness centrality. National contributions to this core group of journals are evaluated for the years 2003, 2004, and 2005. Additionally, the specific class of nanotechnology patents in the database of the U.S. Patent and Trade Office (USPTO) is analyzed to determine if non-patent literature references can be used as a source for the delineation of the knowledge base in terms of scientific journals. The references are primarily to general science journals and l...

Chapter 28 - Nanotechnology for Contaminated Subsurface Remediation: Possibilities and Challenges  

Science Journals Connector (OSTI)

Groundwater represents a significant source of potable and industrial process water throughout the world. With population growth the availability of this precise resource is becoming increasingly scarce. Historically, the subsurface was thought to act as a natural filter of wastes injected into the ground. The potential for these wastes to persist in the subsurface for decades, potentially contaminating drinking water sources was ignored. Not only do toxic compounds have significant detrimental impacts on the environment and human health, there are also economic and social costs associated with contaminated groundwater. Due to increased demands on groundwater resources and historical contamination there is a need to remediate contaminated groundwater to meet current and future demands. At many hazardous sites, however, current remediation technologies routinely defy attempts at satisfactory restoration. As a result new, innovative remediation technologies are required. Nanomaterials are receiving widespread interest in a variety of fields due to their unique, beneficial chemical, physical, and mechanical properties. They have recently been proposed to address a number of environmental problems including the remediation of the contaminated subsurface. A wide variety of nanoparticles, such as metallic (e.g., zero valent iron or bimetallic nanoparticles) and carbon based nanoparticles (e.g., C60 nanoparticles) have been investigated to assess their potential for contaminated site remediation. Studies suggest that nanoparticles have the ability to convert or sequester a wide variety of subsurface contaminants (e.g., chlorinated solvents and heavy metals). In addition they are more reactive than similar, larger sized, reactive materials. The majority of these studies have, however, been conducted at the batch scale. Considerable work is necessary prior to the application of nanotechnology for contaminated site remediation. One problem, for example, is the delivery of reactive nanometals to the contaminated source zone where they will react. This chapter will summarize the use of nanoparticles for contaminated site remediation and highlight some of the challenges that remain unresolved.

Nanotechnology Nanotechnology Consider how far it is from New York to Los Angeles. Now compare that distance to the length of the "l" in "Angeles". That's roughly how one meter compares to one nanometer. A nanometer-one billionth of a meter-is a very small distance almost any way you look at it. One nanometer is about six times the width of a carbon atom. Distances of tens of nanometers are barely significant in much present-day technology, in which "identical" precision machine parts differ that much or more in size with little discernable effect on how well the machines work. But these tiny distances are becoming significant in the new field of nanotechnology --the study of manipulating matter on an atomic and molecular scale.

Nanotechnology for a Safe and Sustainable Water Supply: Enabling Integrated Water Treatment and Reuse  

Science Journals Connector (OSTI)

Nanotechnology for a Safe and Sustainable Water Supply: Enabling Integrated Water Treatment and Reuse ... Although existing infrastructure contributes inertia against a paradigm shift, these immense challenges call for a change toward integrated management of water and wastewater with a decentralized, differential treatment and reuse paradigm where water and wastewater are treated to the quality dictated by the intended use. ... Nanotechnology will likely play a critical role, not only supplementing and enhancing existing processes, but also facilitating the transformation of water supply systems toward a distributed differential treatment paradigm that integrates wastewater reuse with energy neutral operations, lower residuals production, and safer water quality. ...

The Principle of Minimal Resistance in Non-Equilibrium Thermodynamics  

E-Print Network (OSTI)

Analytical models describing the motion of colloidal particles in given velocity fields are presented. In addition to local approaches, leading to well known master equations such as the Langevin and the Fokker-Planck equations, a global description based on path integration is reviewed. This shows that under very broad conditions, during its evolution a dissipative system tends to minimize its energy dissipation in such a way to keep constant the Hamiltonian time rate, equal to the difference between the flux-based and the force-based Rayleigh dissipation functions. At steady state, the Hamiltonian time rate is maximized, leading to a minimum resistance principle. In the unsteady case, we consider the relaxation to equilibrium of harmonic oscillators and the motion of a Brownian particle in shear flow, obtaining results that coincide with the solution of the Fokker-Planck and the Langevin equations.

Non equilibrium dissipation-driven steady many-body entanglement  

E-Print Network (OSTI)

We study an ensemble of two-level quantum systems (qubits) interacting with a common electromagnetic field in proximity of a dielectric slab whose temperature is held different from that of some far surrounding walls. We show that the dissipative dynamics of the qubits driven by this stationary and out of thermal equilibrium (OTE) field, allows the production of steady many-body entangled states, differently from the case at thermal equilibrium where steady states are always non-entangled. By studying up to ten qubits, we point out the role of symmetry in the entanglement production, which is exalted in the case of permutationally invariant configurations. In the case of three qubits, we find a strong dependence of tripartite entanglement on the spatial disposition of the qubits, and in the case of six qubits, we find several highly entangled bipartitions where entanglement can, remarkably, survive for large qubit-qubit distances up to 100 $\\mu$m.

Non-equilibrium electroweak baryogenesis from preheating after inflation  

E-Print Network (OSTI)

We present a novel scenario for baryogenesis in a hybrid inflation model at the electroweak scale, in which the Standard Model Higgs field triggers the end of inflation. One of the conditions for successful baryogenesis, the departure from thermal equilibrium, is naturally achieved at the stage of preheating after inflation. The inflaton oscillations induce large occupation numbers for long-wavelength configurations of Higgs and gauge fields, which leads to a large rate of sphaleron transitions. We estimate this rate during the first stages of reheating and evaluate the amount of baryons produced due to a particular type of higher dimensional CP violating operator. The universe thermalizes through fermion interactions, at a temperature below critical, $T_{rh} < 100$ GeV, preventing the wash-out of the produced baryon asymmetry. Numerical simulations in (1+1) dimensions support our theoretical analysis.

Nanotechnology applications to desalination : a report for the joint water reuse & desalination task force.  

SciTech Connect

Nanomaterials and nanotechnology methods have been an integral part of international research over the past decade. Because many traditional water treatment technologies (e.g. membrane filtration, biofouling, scale inhibition, etc.) depend on nanoscale processes, it is reasonable to expect one outcome of nanotechnology research to be better, nano-engineered water treatment approaches. The most immediate, and possibly greatest, impact of nanotechnology on desalination methods will likely be the development of membranes engineered at the near-molecular level. Aquaporin proteins that channel water across cell membranes with very low energy inputs point to the potential for dramatically improved performance. Aquaporin-laced polymer membranes and aquaporin-mimicking carbon nanotubes and metal oxide membranes developed in the lab support this. A critical limitation to widespread use of nanoengineered desalination membranes will be their scalability to industrial fabrication processes. Subsequent, long-term improvements in nanoengineered membranes may result in self-healing membranes that ideally are (1) more resistant to biofouling, (2) have biocidal properties, and/or (3) selectively target trace contaminants.

In this paper, we use bibliometric methods and social network analysis to analyze the pattern of China-US scientific collaboration on individual level in nanotechnology. Results show that Chinese-American scientists have been playing an important role in China-US scientific collaboration. We find that China-US collaboration in nanotechnology mainly occurs between Chinese and Chinese-American scientists. In the co-authorship network, Chinese-American scientists tend to have higher betweenness centrality. Moreover, the series of polices implemented by the Chinese government to recruit oversea experts seems to contribute a lot to China-US scientific collaboration.

Chapter 22 - Polymer- and Protein-Based Nanotechnologies for Cancer Theranostics  

Science Journals Connector (OSTI)

Nanotechnology-based drug delivery systems have been developed to improve the therapeutic efficacy and reduce the toxicity of a wide range of drugs. They also hold the potential to revolutionize drug development and enable entirely new therapeutic approaches such as gene therapy and RNA interference. To date, approximately ten therapeutic nanoparticles have been validated in cancer treatment, mainly through the improvement of clinical benefits of a narrow range of previously approved drugs. This has inspired the development of next-generation therapeutic nanoparticles with additional capabilities, such as targeted delivery, controlled drug release, and stimuli-responsiveness, to further enhance drug delivery and therapeutic efficacy. On the other hand, theranostic nanotechnologies, which simultaneously combine therapeutic and imaging agents within one nanoparticle, aim to improve the patient outcome through realizing the development of personalized nanomedicine for cancer patients. With noninvasive imaging techniques such as nuclear imaging and magnetic resonance imaging, theranostic nanoparticles can provide real-time information about pharmacokinetics, biodistribution, tumor accumulation, drug distribution at the target site, and therapeutic response. This facilitates the clinical evaluation and optimization of nanotherapeutics, and can be used to prescreen cancer patients and reevaluate/alter their original treatment plan. This chapter reviews the development of polymer- and protein-based nanoparticle platforms for theranostic applications, and discusses the opportunities and challenges that the clinical translation of theranostic nanoparticles may encounter.

Nanotechnology at the interface of cell biology, materials science and medicine  

Science Journals Connector (OSTI)

The atomic force microscope (AFM) and related scanning probe microscopes have become resourceful tools to study cells, supramolecular assemblies and single biomolecules, because they allow investigations of such structures in native environments. Quantitative information has been gathered about the surface structure of membrane proteins to lateral and vertical resolutions of 0.5 nm and 0.1 nm, respectively, about the forces that keep protein–protein and protein–nucleic acid assemblies together as well as single proteins in their native conformation, and about the nanomechanical properties of cells in health and disease. Such progress has been achieved mainly because of constant development of AFM instrumentation and sample preparation methods. This special issue of Nanotechnology presents papers from leading laboratories in the field of nanobiology, covering a wide range of topics in the form of original and novel scientific contributions. It addresses achievements in instrumentation, sample preparation, automation and in biological applications. These papers document the creativity and persistence of researchers pursuing the goal to unravel the structure and dynamics of cells, supramolecuar structures and single biomolecules at work. Improved cantilever sensors, novel optical probes, and quantitative data on supports for electrochemical experiments open new avenues for characterizing biological nanomachines down to the single molecule. Comparative measurements of healthy and metastatic cells promise new methods for early detection of tumors, and possible assessments of drug efficacy. High-speed AFMs document possibilities to monitor crystal growth and to observe large structures at video rate. A wealth of information on amyloid-type fibers as well as on membrane proteins has been gathered by single molecule force spectroscopy—a technology now being automated for large-scale data collection. With the progress of basic research and a strong industry supporting instrumentation development by improving robustness and reliability and making new instruments available to the community, nanobiology has the potential to develop into a field with great impact on our understanding of the complexity of life, and to provide a major contribution to human health. This special issue of Nanotechnology on nanobiology would not have been possible without the highly professional support from Nina Couzin, Amy Harvey and the Nanotechnology team at IOP Publishing. We are thankful for their most constructive and effective help in pushing the project forward. We are also thankful to all the authors who have contributed with excellent original articles, as well as to the referees who have helped to make this special issue such an insightful document of a rapidly moving field.

Semiconductor nanotechnology: novel materials and devices for electronics, photonics and renewable energy applications  

Science Journals Connector (OSTI)

Electronic and photonic information technology and renewable energy alternatives, such as solar energy, fuel cells and batteries, have now reached an advanced stage in their development. Cost-effective improvements to current technological approaches have made great progress, but certain challenges remain. As feature sizes of the latest generations of electronic devices are approaching atomic dimensions, circuit speeds are now being limited by interconnect bottlenecks. This has prompted innovations such as the introduction of new materials into microelectronics manufacturing at an unprecedented rate and alternative technologies to silicon CMOS architectures. Despite the environmental impact of conventional fossil fuel consumption, the low cost of these energy sources has been a long-standing economic barrier to the development of alternative and more efficient renewable energy sources, fuel cells and batteries. In the face of mounting environmental concerns, interest in such alternative energy sources has grown. It is now widely accepted that nanotechnology offers potential solutions for securing future progress in information and energy technologies. The Canadian Semiconductor Technology Conference (CSTC) forum was established 25 years ago in Ottawa as an important symbol of the intrinsic strength of the Canadian semiconductor research and development community, and the Canadian semiconductor industry as a whole. In 2007, the 13th CSTC was held in Montreal, moving for the first time outside the national capital region. The first three meetings in the series of 'Nano and Giga Challenges in Electronics and Photonics'— NGCM2002 in Moscow, NGCM2004 in Krakow, and NGC2007 in Phoenix— were focused on interdisciplinary research from the fundamentals of materials science to the development of new system architectures. In 2009 NGC2009 and the 14th Canadian Semiconductor Technology Conference (CSTC2009) were held as a joint event, hosted by McMaster University (10–14 August, Hamilton, Ontario, Canada) and the scope was expanded to include renewable energy research and development. This special issue of Nanotechnology is devoted to a better understanding of the function and design of semiconductor devices that are relevant to information technology (both electronics and photonics based) and renewable energy applications. The papers contained in this special issue are selected from the NGC/CSTC2009 symposium. Among them is a report by Ray LaPierre from McMaster University and colleagues at the University of Waterloo in Canada on the ability to manipulate single spins in nanowire quantum bits. The paper also reports the development of a testbed of a few qubits for general quantum information processing tasks [1]. Lower cost and greater energy conversion efficiency compared with thin film devices have led to a high level of activity in nanowire research related to photovoltaic applications. This special issue also contains results from an impedance spectroscopy study of core–shell GaAs nanowires to throw light on the transport and recombination mechanisms relevant to solar cell research [2]. Information technology research and renewable energy sources are research areas of enormous public interest. This special issue addresses both theoretical and experimental achievements and provides a stimulating outlook for technological developments in these highly topical fields of research.

E-Print Network (OSTI)

The wide range of interesting electromagnetic behavior of contemporary materials requires that experimentalists working in this field master many diverse measurement techniques and have a broad understanding of condensed matter physics and biophysics. Measurement of the electromagnetic response of materials at microwave frequencies is important for both fundamental and practical reasons. In this paper, we propose a novel near-field microwave sensor with application to material characterization, biology, and nanotechnology. The sensor is based on a subwavelength ferrite-disk resonator with magnetic-dipolar-mode (MDM) oscillations. Strong energy concentration and unique topological structures of the near fields originated from the MDM resonators allow effective measuring material parameters in microwaves, both for ordinary structures and objects with chiral properties.

An Evaluation of Impacts in "Nanoscience & nanotechnology:" Steps towards standards for citation analysis  

E-Print Network (OSTI)

One is inclined to conceptualize impact in terms of citations per publication, and thus as an average. However, citation distributions are skewed, and the average has the disadvantage that the number of publications is used in the denominator. Using hundred percentiles, one can integrate the normalized citation curve and develop an indicator that can be compared across document sets because percentile ranks are defined at the article level. I apply this indicator to the set of 58 journals in the ISI Subject Category of "Nanoscience & nanotechnology," and rank journals, countries, cities, and institutes using non-parametric statistics. The significance levels of results can thus be indicated. The results are first compared with the ISI-Impact Factors, but this Integrated Impact Indicator (I3) can be used with any set downloaded from the (Social) Science Citation Index. The software is made publicly available at the Internet. Visualization techniques are also specified for evaluation by positioning institut...

Nanotechnology meets 3D in vitro models: Tissue engineered tumors and cancer therapies  

Science Journals Connector (OSTI)

Abstract Advances in nanotechnology are providing to medicine a new dimension. Multifunctional nanomaterials with diagnostics and treatment modalities integrated in one nanoparticle or in cooperative nanosystems are promoting new insights to cancer treatment and diagnosis. The recent convergence between tissue engineering and cancer is gradually moving towards the development of 3D disease models that more closely resemble in vivo characteristics of tumors. However, the current nanomaterials based therapies are accomplished mainly in 2D cell cultures or in complex in vivo models. The development of new platforms to evaluate nano-based therapies in parallel with possible toxic effects will allow the design of nanomaterials for biomedical applications prior to in vivo studies. Therefore, this review focuses on how 3D in vitro models can be applied to study tumor biology, nanotoxicology and to evaluate nanomaterial based therapies.

Enhancing Graduate Student Communication to General Audiences through Blogging about Nanotechnology and Sustainability  

SciTech Connect

We have developed and assessed a multiauthor science blog on the topic of nanotechnology and sustainability as a tool to improve the written communication and public engagement skills of graduate students. Focus group studies revealed that after participation in the blog, student authors felt more confident and capable of communicating technical topics to general audiences. Students' research mentors viewed this as an important component of their students' education, as indicated by survey data. Important design aspects of this effort include participation of an editor as well as having flexible content and target-audience guidelines. We have explicitly outlined aspects of the effort we see as critical in order to enable others to replicate this model in related settings.

A review of age-old antimalarial drug to combat malaria: efficacy up-gradation by nanotechnology based drug delivery  

Science Journals Connector (OSTI)

Abstract Malaria is uncontrolled burden in the world till now. Despite of different efforts to develop antimalarial drug for decades, any anti-malarial drug can able to eradicate completely till now. Many anti-malarial substances are practically ineffectual because of their physicochemical limitations, cytotoxicity, chemical instability and degradation, and limited activities against intracellular parasites. Taking into consideration, the amount of research is going to conduct in the field of nanoparticle based drug delivery systems, lead to new ways of improving the treatment of infectious diseases. The study has focused on the progress and advancement of research on nanotechnology based drug delivery to eradicate the malaria. We like to focus the efficacy of nanotechnology based drug application for the opening out of novel chemotherapeutics in laboratory research, which may show the way to better use with age-old antimalarial drug and may draw the attention of pharmaceutical industries for the improvement and designing of effective anti-malarial drugs in future.

High-Efficiency Solid State Cooling Technologies: Non-Equilibrium Asymmetic Thermoelectrics (NEAT) Devices  

SciTech Connect

BEETIT Project: Sheetak is developing a thermoelectric-based solid state cooling system to replace typical air conditioners that use vapor compression to cool air. With noisy mechanical components, vapor compression systems use a liquid refrigerant to circulate within the air conditioner, absorb heat, and pump the heat out into the external environment. With no noisy moving parts or polluting refrigerants, thermoelectric systems rely on an electrical current being passed through the junction of the two different conducting materials to change temperature. Using advanced semiconductor technology, Sheetak is improving solid state cooling systems by using proprietary thermoelectric materials along with other innovations to achieve significant energy efficiency. Sheetak’s new design displaces compressor-based technology; improves reliability; and decreases energy usage. Sheetak’s use of semiconductor manufacturing methods leads to less material use—facilitating cheaper production.

Non-equilibrium self-assembly of a filament coupled to ATP/GTP hydrolysis  

E-Print Network (OSTI)

We study the stochastic dynamics of growth and shrinkage of single actin filaments or microtubules taking into account insertion, removal, and ATP/GTP hydrolysis of subunits. The resulting phase diagram contains three different phases: a rapidly growing phase, an intermediate phase and a bound phase. We analyze all these phases, with an emphasis on the bound phase. We also discuss how hydrolysis affects force-velocity curves. The bound phase shows features of dynamic instability, which we characterize in terms of the time needed for the ATP/GTP cap to disappear as well as the time needed for the filament to reach a length of zero, i.e., (to collapse) for the first time. We obtain exact expressions for all these quantities, which we test using Monte Carlo simulations.

Non-equilibrium coherent vortex states and subharmonic giant Shapiro steps in Josephson junction arrays  

E-Print Network (OSTI)

This is a review of recent work on the dynamic response of Josephson junction arrays driven by dc and ac currents. The arrays are modeled by the resistively shunted Josephson junction model, appropriate for proximity effect junctions, including self-induced magnetic fields as well as disorder. The relevance of the self-induced fields is measured as a function of a parameter $\\kappa=\\lambda_L/a$, with $\\lambda_L$ the London penetration depth of the arrays, and $a$ the lattice spacing. The transition from Type II ($\\kappa>1$) to Type I ($\\kappa <1$) behavior is studied in detail. We compare the results for models with self, self+nearest-neighbor, and full inductance matrices. In the $\\kappa=\\infty$ limit, we find that when the initial state has at least one vortex-antivortex pair, after a characteristic transient time these vortices unbind and {\\it radiate} other vortices. These radiated vortices settle into a parity-broken, time-periodic, {\\em axisymmetric coherent vortex state} (ACVS), characterized by alternate rows of positive and negative vortices lying along a tilted axis. The ACVS produces subharmonic steps in the current voltage (IV) characteristics, typical of giant Shapiro steps. For finite $\\kappa$ we find that the IV's show subharmonic giant Shapiro steps, even at zero external magnetic field. We find that these subharmonic steps are produced by a whole family of coherent vortex oscillating patterns, with their structure changing as a function of $\\kappa$. In general, we find that these patterns are due to a break down of translational invariance produced, for example, by disorder or antisymmetric edge-fields. The zero field case results are in good qualitative agreement with experiments

Finite-Temperature Non-equilibrium Quasicontinuum Method based on Langevin Dynamics  

SciTech Connect

The concurrent bridging of molecular dynamics and continuum thermodynamics presents a number of challenges, mostly associated with energy transmission and changes in the constitutive description of a material across domain boundaries. In this paper, we propose a framework for simulating coarse dynamic systems in the canonical ensemble using the Quasicontinuum method (QC). The equations of motion are expressed in reduced QC coordinates and are strictly derived from dissipative Lagrangian mechanics. The derivation naturally leads to a classical Langevin implementation where the timescale is governed by vibrations emanating from the finest length scale occurring in the computational cell. The equations of motion are integrated explicitly via Newmark's ({beta} = 0; {gamma} = 1/2) method, leading to a robust numerical behavior and energy conservation. In its current form, the method only allows for wave propagations supported by the less compliant of the two meshes across a heterogeneous boundary, which requires the use of overdamped dynamics to avoid spurious heating due to reflected vibrations. We have applied the method to two independent crystallographic systems characterized by different interatomic potentials (Al and Ta) and have measured thermal expansion in order to quantify the vibrational entropy loss due to homogenization. We rationalize the results in terms of system size, mesh coarseness, and nodal cluster diameter within the framework of the quasiharmonic approximation. For Al, we find that the entropy loss introduced by mesh coarsening varies linearly with the element size, and that volumetric effects are not critical in driving the anharmonic behavior of the simulated systems. In Ta, the anomalies of the interatomic potential employed result in negative and zero thermal expansion at low and high temperatures, respectively.

Risk Assessment and Monitoring of Stored CO2 in Organic Rocks Under Non-Equilibrium Conditions  

SciTech Connect

The USA is embarking upon tackling the serious environmental challenges posed to the world by greenhouse gases, especially carbon dioxide (CO2). The dimension of the problem is daunting. In fact, according to the Energy Information Agency, nearly 6 billion metric tons of CO2 were produced in the USA in 2007 with coal-burning power plants contributing about 2 billion metric tons. To mitigate the concerns associated with CO2 emission, geological sequestration holds promise. Among the potential geological storage sites, unmineable coal seams and shale formations in particular show promise because of the probability of methane recovery while sequestering the CO2. However. the success of large-scale sequestration of CO2 in coal and shale would hinge on a thorough understanding of CO2's interactions with host reservoirs. An important parameter for successful storage of CO2 reservoirs would be whether the pressurized CO2 would remain invariant in coal and shale formations under reasonable internal and/or external perturbations. Recent research has brought to the fore the potential of induced seismicity, which may result in caprock compromise. Therefore, to evaluate the potential risks involved in sequestering CO2 in Illinois bituminous coal seams and shale, we studied: (i) the mechanical behavior of Murphysboro (Illinois) and Houchin Creek (Illinois) coals, (ii) thermodynamic behavior of Illinois bituminous coal at - 100oC ? T ? 300oC, (iii) how high pressure CO2 (up to 20.7 MPa) modifies the viscosity of the host, (iv) the rate of emission of CO2 from Illinois bituminous coal and shale cores if the cores, which were pressurized with high pressure (? 20.7 MPa) CO2, were exposed to an atmospheric pressure, simulating the development of leakage pathways, (v) whether there are any fractions of CO2 stored in these hosts which are resistance to emission by simply exposing the cores to atmospheric pressure, and (vi) how compressive shockwaves applied to the coal and shale cores, which were pressurized with high pressure CO2, determine the fate of sequestered CO2 in these cores. Our results suggested that Illinois bituminous coal in its unperturbed state, i.e., when not pressurized with CO2, showed large variations in the mechanical properties. Modulus varied from 0.7 GPa to 3.4 GPa even though samples were extracted from a single large chunk of coal. We did not observe any glass transition for Illinois bituminous coal at - 100oC ? T ? 300oC, however, when the coal was pressurized with CO2 at ambient ? P ? 20.7 MPa, the viscosity of the coal decreased and inversely scaled with the CO2 pressure. The decrease in viscosity as a function of pressure could pose CO2 injection problems for coal as lower viscosity would allow the solid coal to flow to plug the fractures, fissures, and cleats. Our experiments also showed a very small fraction of CO2 was absorbed in coal; and when CO2 pressurized coals were exposed to atmospheric conditions, the loss of CO2 from coals was massive. Half of the sequestered gas from the coal cores was lost in less than 20 minutes. Our shockwave experiments on Illinois bituminous coal, New Albany shale (Illinois), Devonian shale (Ohio), and Utica shale (Ohio) presented clear evidence that the significant emission of the sequestered CO2 from these formations cannot be discounted during seismic activity, especially if caprock is compromised. It is argued that additional shockwave studies, both compressive and transverse, would be required for successfully mapping the risks associated with sequestering high pressure CO2 in coal and shale formations.

Flux-difference split parabolized Navier-Stokes algorithm for non-equilibrium chemically reacting flows  

SciTech Connect

A flux-difference split explicit finite-difference algorithm is presented for solving the parabolized form of the equations governing three-dimensional nonequilibrium chemically reacting flows. The algorithm is based on an explicit noniterative, upwind space-marching scheme developed by Korte, but differs in that the unsteady Riemann problem, rather than the steady Riemann problem, is solved. The algorithm allows either a second or an approximately third-order accurate upwind treatment of the convection terms by employing the unsteady approximate Riemann solver of Roe. The source terms of the species transport equations are treated in either an explicit or implicit manner, and the species diffusion terms are modeled with either a Fickian or a multicomponent model. A validation of the algorithm is performed by comparing computational results with the 2-D Mach 14, 15 degree compression-corner data of Holden. The three-dimensional capability of the algorithm is demonstrated by computing Mach 2.7 flow over a swept wedge scramjet fuel injector, and three-dimensional reacting flow capability is demonstrated by a computing a shock-jet interaction concept for mixing and combustion enhancement. 34 refs.

Stochastic thermodynamics of fluctuating density fields: Non-equilibrium free energy differences under coarse-graining  

SciTech Connect

We discuss the stochastic thermodynamics of systems that are described by a time-dependent density field, for example, simple liquids and colloidal suspensions. For a time-dependent change of external parameters, we show that the Jarzynski relation connecting work with the change of free energy holds if the time evolution of the density follows the Kawasaki-Dean equation. Specifically, we study the work distributions for the compression and expansion of a two-dimensional colloidal model suspension implementing a practical coarse-graining scheme of the microscopic particle positions. We demonstrate that even if coarse-grained dynamics and density functional do not match, the fluctuation relations for the work still hold albeit for a different, apparent, change of free energy.

Non-equilibrium raft-like membrane domains under continuous recycling  

E-Print Network (OSTI)

We present a model for the kinetics of spontaneous membrane domain (raft) assembly that includes the effect of membrane recycling ubiquitous in living cells. We show that the domains have a broad power-law distribution with an average radius that scales with the 1/4 power of the domain lifetime when the line tension at the domain edges is large. For biologically reasonable recycling and diffusion rates the average domain radius is in the tens of nm range, consistent with observations. This represents one possible link between signaling (involving rafts) and traffic (recycling) in cells. Finally, we present evidence that suggests that the average raft size may be the same for all scale-free recycling schemes.

The Influence of Hydraulic Non-Equilibrium on Pressure Plate Data  

SciTech Connect

Pressure plates are used routinely to measure water retention characteristics of soils. Plates of varying porosity are used depending on the pressure range of interest. For applied pressures up to 1.5 MPa, 15-bar porous ceramic plates with fine porosity are used because of their high bubbling pressure (>15 bar), which limits airflow through the plate. The typical saturated hydraulic conductivity of the 15-bar plate is less than 1x10-13 m s-1. Low plate conductance coupled with decreasing soil hydraulic conductivities (e.g., <1x10-13 m s-1) at high pressures strongly influence equilibrium times, which theoretically may extend to months or years. We measured the soil water pressures (suctions) for three soils, a sand, a silt loam, and a clay placed on 15-bar pressure plates for 10 days or longer, with and without static loads and with and without use of a kaolinite slurry for improved plate contact. Total matric suctions, inferred from peltier psychrometry data, were always less than 1.5 MPa. When sample height was increased from 1.5 cm to 3 cm, the water contents increased and total suctions decreased to 0.15 MPa for sand, 0.3 MPa for silt loam, and 0.55 MPa for clay. These data suggest that alternative methods to pressure plates may be require to measure equilibrium water suctions of soils in reasonable times in the 15-bar pressure range and that loading of the samples and use of kaolinite appear to be ineffective in speeding equilibrium.

Our main activity has been doing lab experiments where plasmas having morphology and behavior similar to solar and astrophysical plasmas are produced and studied. The solar experiment is mounted on one end of a large vacuum chamber while the astrophysical jet experiment is mounted on the other end. Diagnostics are shared between the two experiments. The solar experiment produces arched plasma loops that behave very much like solar corona loops. The astrophysical jet experiment produces plasma jets that are very much like astrophysical jets. We have also done work on plasma waves, including general wave dispersions, and specific properties of kinetic Alfven waves and of whistler waves.

Thermo-chemical dynamics and chemical quasi-equilibrium of plasmas in thermal non-equilibrium  

SciTech Connect

We examine both processes of ionization by electron and heavy-particle impact in spatially uniform plasmas at rest in the absence of external forces. A singular perturbation analysis is used to study the following physical scenario, in which thermal relaxation becomes much slower than chemical reactions. First, electron-impact ionization is investigated. The dynamics of the system rapidly becomes close to a slow dynamics manifold that allows for defining a unique chemical quasi-equilibrium for two-temperature plasmas and proving that the second law of thermodynamics is satisfied. Then, all ionization reactions are taken into account simultaneously, leading to a surprising conclusion: the inner layer for short time scale (or time boundary layer) directly leads to thermal equilibrium. Global thermo-chemical equilibrium is reached within a short time scale, involving only chemical reactions, even if thermal relaxation through elastic collisions is assumed to be slow.

The 6th International Workshop on Micro and Nanotechnologies for Power Generation and Energy Conversion Applications (PowerMEMS 2006)  

Science Journals Connector (OSTI)

Energy is a sector of paramount importance over the coming decades if we are to ensure sustainable development that respects our environment. The research and development of novel approaches to convert available energy into usable forms using micro and nanotechnologies can contribute towards this goal and meet the growing need for power in small scale portable applications. The dominant power sources for handheld and other portable electronics are currently primary and rechargeable batteries. Their limited energy density and adverse effects on the environment upon disposal suggest that alternative approaches need to be explored. This special issue will showcase some of the leading work in this area, initially presented at PowerMEMS 2006, the 6th International Workshop on Micro and Nanotechnologies for Power Generation and Energy Conversion Applications. Power MEMS are defined as microsystems for electrical power generation and other energy conversion applications, including propulsion and cooling. The range of power MEMS technologies includes micro thermodynamic machines, such as microturbines, miniature internal combustion engines and micro-coolers; solid-state direct energy conversion, such as thermoelectric and photovoltaic microstructures; micro electrochemical devices, such as micro fuel cells and nanostructure batteries; vibration energy harvesting devices, such as piezoelectric, magnetic or electrostatic micro generators, as well as micro thrusters and rocket engines for propulsion. These can either be driven by scavenging thermal, mechanical or solar energy from the environment, or from a stored energy source, such as chemical fuel or radioactive material. The unique scope leads to unique challenges in the development of power MEMS, ranging from the integration of novel materials to the efficient small scale implementation of energy conversion principles. In this special issue, Mitcheson et al provide a comparative assessment of three inertial vibration energy harvesting approaches. Technologies and approaches for micro heat engines are shared, ranging from a complete microsystem for thermal energy harvesting (Cho et al) to core bearing and microturbomachinery technologies for rotating micro heat engines (Waits et al, Nakajima et al). Electrochemical microsystems are also presented, based on methanol as fuel (Morse et al), as well as novel micro and nanofabrication approaches (Chu et al). Fuel cell microsystems with integrated hydrogen generation approaches are also investigated by Peterson et al and Varady et al, illustrating the benefits and challenges of miniaturizing complete power sources. Finally, biological micro fuel cells that leverage the principles found in nature are presented, in contrast to chemical fuel cells (Chen et al, Morishima et al). We hope that this work will inspire others to pursue innovative research and development activities in the area of power MEMS, and consequently contribute to addressing our energy challenges for the 21st century.

Synthesis and characterisation of new designed protoporphyrin-stabilised gold nanoparticles for cancer cells nanotechnology-based targeting  

Science Journals Connector (OSTI)

Nanotechnology has entered the field of medicine in recent dacades and especially, in drug delivery systems, nanoparticles have shown an ability to improve pharmacokinetics, pharmacodynamics, efficacy and to reduce the toxicity of associated drugs. In this study, we have designed a new protoporphyrin-conjugated gold nanoparticle to selectively target and photo- or sonodynamic therapy of tumoural cells. In order to improve the cell uptake effect of protoporphyrin and their derivatives, gold nanoparticle was chosen as carrier. For this purpose, we used 6-mercapto-1-hexanol, as a bifunctional linker to react with protoporphyrin with an ester-linkage formation. Then, we conjugated the thiol-terminated protoporphyrin to the gold nanoparticles through a fast and single-phase system reaction with HAuCl4 in the presence of sodium borohydride. Finally, we evaluated the specific interaction between the protoporphyrin and gold nanoparticles by the elemental analysis, atomic absorption and UV-vis spectrum. Transmission electron microscopic images reveal the spherical gold nanoparticles formation with the average size about 7 nm. Therefore, we have synthesised gold nanoparticle conjugates with protoporphyrin which could be used as a biocompatible drug delivery system.

Non-equilibrium deposition of phase pure Cu{sub 2}O thin films at reduced growth temperature  

SciTech Connect

Cuprous oxide (Cu{sub 2}O) is actively studied as a prototypical material for energy conversion and electronic applications. Here we reduce the growth temperature of phase pure Cu{sub 2}O thin films to 300?°C by intentionally controlling solely the kinetic parameter (total chamber pressure, P{sub tot}) at fixed thermodynamic condition (0.25 mTorr pO{sub 2}). A strong non-monotonic effect of P{sub tot} on Cu-O phase formation is found using high-throughput combinatorial-pulsed laser deposition. This discovery creates new opportunities for the growth of Cu{sub 2}O devices with low thermal budget and illustrates the importance of kinetic effects for the synthesis of metastable materials with useful properties.

Non-equilibrium Quantum Many-Body Green Function Formalism in the light of Quantum Information Theory  

E-Print Network (OSTI)

The following issues are discussed inspired by the recent paper of Kadanoff (arXiv: 1403:6162): (a) Construction of a generalized one-particle Wigner distribution (GWD) function (analog of the classical distribution function) from which the quantum kinetic equation due to Kadanoff and Baym (KB) is derived, often called the Quantum Boltzmann Equation (QBE); (b) The equation obeyed by this has a collision contribution in the form of a two-particle Green function. This term is manipulated to have Kinetic Entropy in parallel to its counterpart in the classical Boltzmann kinetic equation for the classical distribution function. This proved to be problematic in that unlike in the classical Boltzmann kinetic equation, the contribution from the kinetic entropy term was non-positive; (3) Kadanoff surmised that this situation could perhaps be related to quantum entanglement that may not have been included in his theory. It is shown that GWD is not positive everywhere (indicating dynamical quantumness) just like the commonly recognized property of the Wigner function (negative property indicating quantumness of the state). The issue of non-positive feature appearing in approximate evaluation of patently positive entities in many particle systems is here pointed to an early discussion of this issue (Phys. Rev. A10, 1852 (1974)) in terms of a theorem on truncation of cumulant expansion of a probability distribution function due to Marcinkeiwicz. The last issue of presence or absence of entanglement in an approximate evaluation of a many particle correlation poses a new problem; it is considered here in terms of fermionic entanglement theory in the light of density matrix and Green function theory of many-fermion systems. The clue comes from the fact that the Hartree-Fock approximation exhbits no entantanglement in two-particle fermion density matrix and hence also in two-particle Green function.

Steady-state film-boiling data in rod-bundle geometry and non-equilibrium correlation assessment  

SciTech Connect

A series of 22 steady-state, rod bundle, dispersed flow film boiling experiments has been performed in the Thermal-Hydraulic Test Facility (THTF), a pressurized-water loop containing 64 full-length electrically heated rods. Test parameters in the upflow experiments cover a wide range of conditions typical of those which might be encountered during a nuclear reactor loss-of-coolant accident. Local equilibrium fluid conditions were calculated using mass and energy conservation considerations. Experimentally determined heat transfer coefficients were compared to several available film boiling heat transfer correlations: Dougall-Rohsenow, Groeneveld 5.7, Groeneveld-Delorme, Chen, Jones-Zuber, and Yoder-Rohsenow. The Groeneveld 5.7 correlation tended to predict the data better than any other correlation tested. The Dougall-Rohsenow correlation tends to overpredict the data while the Yoder-Rohsenow correlation predicted the data better than the other nonequilibrium correlations examined. However, all of the nonequilibrium correlations generally underpredict the heat transfer.

Chemical freeze-outs of strange and non-strange particles and residual chemical non-equilibrium  

E-Print Network (OSTI)

We propose an elaborate version of the hadron resonance gas model with the combined treatment of separate chemical freeze-outs for strange and non-strange hadrons and with an additional \\gamma_{s} factor which accounts for the remaining strange particle non-equilibration. Two sets of chemical freeze-outs parameters are connected by the conservation laws of entropy, baryonic charge, isospin projection and strangeness. The developed approach enables us to perform a high-quality fit of the hadron multiplicity ratios for AGS, SPS and RHIC energies with total \\chi^2/dof \\simeq 1.05. A special attention is paid to a complete description of the Strangeness Horn. A well-known \\bar p, \\bar \\Lambda and \\bar \\Xi selective suppression problem is also discussed.

Evaluation of technical feasibility of closed-cycle non-equilibrium MHD power generation with direct coal firing. Final report, Task 1  

SciTech Connect

Program accomplishments in a continuing effort to demonstrate the feasibility of direct coal fired, closed cycle, magnetohydrodynamic power generation are detailed. These accomplishments relate to all system aspects of a CCMHD power generation system including coal combustion, heat transfer to the MHD working fluid, MHD power generation, heat and cesium seed recovery and overall systems analysis. Direct coal firing of the combined cycle has been under laboratory development in the form of a high slag rejection, regeneratively air cooled cyclone coal combustor concept, originated within this program. A hot bottom ceramic regenerative heat exchanger system was assembled and test fired with coal for the purposes of evaluating the catalytic effect of alumina on NO/sub x/ emission reduction and operability of the refractory dome support system. Design, procurement, fabrication and partial installation of a heat and seed recovery flow apparatus was accomplished and was based on a stream tube model of the full scale system using full scale temperatures, tube sizes, rates of temperature change and tube geometry. Systems analysis capability was substantially upgraded by the incorporation of a revised systems code, with emphasis on ease of operator interaction as well as separability of component subroutines. The updated code was used in the development of a new plant configuration, the Feedwater Cooled (FCB) Brayton Cycle, which is superior to the CCMHD/Steam cycle both in performance and cost. (WHK)
