Min CSP on Four Elements: Moving Beyond Submodularity  

E-Print Network (OSTI)

We report new results on the complexity of the valued constraint satisfaction problem (VCSP). Under the unique games conjecture, the approximability of finite-valued VCSP is fairly well-understood. However, there is yet no characterisation of VCSPs that can be solved exactly in polynomial time. This is unsatisfactory, since such results are interesting from a combinatorial optimisation perspective; there are deep connections with, for instance, submodular and bisubmodular minimisation. We consider the Min and Max CSP problems (i.e. where the cost functions only attain values in {0,1}) over four-element domains and identify all tractable fragments. Similar classifications were previously known for two- and three-element domains. In the process, we introduce a new class of tractable VCSPs based on a generalisation of submodularity. We also extend and modify a graph-based technique by Zivny and Kolmogorov (originally introduced by Takhanov) for efficiently obtaining hardness results in our setting. This allow us...

Magnetic Moments of 69-min Ag104 and 27-min Ag104m  

Science Journals Connector (OSTI)

The hyperfine structure separations of 69-min Ag104 and of 27-min Ag104m have been measured using the atomic beam magnetic resonance method. The results are: ??I=5(69-minAg104)=33 500-1000+2000 Mc/sec, ??I=2(27-minAg104m)=35 0002000 Mc/sec. The sign of the nuclear magnetic dipole moment has been found to be positive for both states, and by use of the Fermi-Segr formula one obtains ?I(I=5)=+4.0-0.1+0.2 nm, ?I(I=2)=+3.70.2 nm. Nuclear configurations which give these moments are discussed and we comment on the difference between Ag104 which shows a 2+, 5+ angular momentum recoupling doublet and Ag106 and Ag110 which show a 1+, 6+ doublet.

Detection of chlorinated aromatic compounds  

DOE Patents (OSTI)

A method for making a composition for measuring the concentration of chloated aromatic compounds in aqueous fluids, and an optical probe for use with the method. The composition comprises a hydrophobic polymer matrix, preferably polyamide, with a fluorescent indicator uniformly dispersed therein. The indicator fluoresces in the presence of the chlorinated aromatic compounds with an intensity dependent on the concentration of these compounds in the fluid of interest, such as 8-amino-2-naphthalene sulfonate. The probe includes a hollow cylindrical housing that contains the composition in its distal end. The probe admits an aqueous fluid to the probe interior for exposure to the composition. An optical fiber transmits excitation light from a remote source to the composition while the indicator reacts with chlorinated aromatic compounds present in the fluid. The resulting fluorescence light signal is reflected to a second optical fiber that transmits the light to a spectrophotometer for analysis.

Decay of 37.5-min Th236 and 9.1-min Pa236  

Science Journals Connector (OSTI)

The decays of Th236 and its Pa236 daughter were studied by ?-ray spectroscopy. By means of radiochemical methods and a continuous separation technique pure sources of parent and daughter were prepared so that each was free (or almost free) of the other. For Th236, 14 of the 17 observed ? rays are new; for Pa236 16 new ? rays were found. Absolute intensities of all the ? rays were determined with the aid of 4? beta measurements on Pa236. A new decay scheme is proposed for Th236 and a considerably expanded one is given for Pa236. The half-lives determined are 37.50.2 min for Th236 and 9.10.1 min for Pa236.

Alkylation of organic aromatic compounds  

DOE Patents (OSTI)

Aromatic compounds are alkylated in a catalytic distillation, wherein the catalyst structure also serves as a distillation component by contacting the aromatic compound with a C[sub 2] to C[sub 10] olefin in the catalyst bed under 0.25 to 50 atmospheres of pressure and at temperatures in the range of 80 C to 500 C, using as the catalyst a mole sieve characterized as acidic or an acidic cation exchange resin. For example, ethyl benzene is produced by feeding ethylene below the catalyst bed while benzene is conveniently added through the reflux in molar excess to that required to react with ethylene, thereby reacting substantially all of the ethylene and recovering benzene as the principal overhead and ethyl benzene in the bottoms. 1 fig.

Neurton Damage and MAX Phase Ternary Compounds  

SciTech Connect

The Demands of Gen IV nuclear power plants for long service life under neutron radiation at high temperature are severe. Advanced materials that would withstand high temperatures (up to 1000+ C) to high doses in a neutron field would be ideal for reactor internal structures and would add to the long service life and reliability of the reactors. The objective of this work is to investigate the resonse of a new class of machinable, conductive, layered, ternary transition metal carbides and nitrides - the so-called MAX phases - to low and moderate neutron dose levels.

The MAX facility for CFD code validation  

SciTech Connect

ANL has recently completed construction of a fluid dynamics test facility devised to provide validation data for CFD simulation tools used to evaluate various aspects of nuclear power plant design and safety. Experiments with the facility involve mixing air jets within a 1x1x1.7m long glass tank at atmospheric pressure. A particle image velocimetry system measures flow velocity and turbulence quantities within the tank while a high-speed infrared camera records temperatures across the tank lid. The tandem of high fidelity thermal and turbulence data is particularly useful for benchmarking transient heat transfer phenomena such as thermal striping. This paper describes the MAX facility, preliminary data obtained during shakedown tests, and the results of companion CFD calculations employing RANS-based Star-CCM+ and large eddy simulations with Nek 5000.

SciTech Connect

Semi-preparative scale high-pressure liquid chromatography using bonded normal-phase columns offers an attractive alternative to the classical solvent partition/adsorption column chromatographic procedure for obtaining polycyclic aromatic hydrocarbons (PAH) or a polycyclic aromatic amines (PAA) fraction of purity suitable for analysis by gas chromatography. Sample matrices ranging from fossil fuels to air particulate extracts can be fractionated successfully if the appropriate polarity column is chosen. The apparatus is low-cost, gives reproducible results, does not require an expensive solvent gradient programmer, and can operate unattended.

The process comprises contacting the process stream, which contains trace olefins in an amount of from about 50 to about 2000 as measured by Bromine Index and at least 80% by weight of aromatic and naphthenic hydrocarbons having from 6 to 20 carbon atoms per molecule, at reaction conditions which ensure liquid phase operation with a solid catalyst composite comprising a crystalline aluminosilicate zeolite and a refractory inorganic oxide. A catalytic olefin-consuming alkylation reaction then produces an essentially olefinfree product stream with approximately the same quantity and distribution of aromatic and naphthenic hydrocarbons as contained in the process stream.

Improved procedure for extraction of aromatic bases from synfuel materials. [Aromatic amines; azaarenes  

SciTech Connect

The present study was undertaken to evaluate the conventional aqueous acidbase extraction procedures and to explore alternate conditions for optimizing recovery of aromatic bases. For four procedures the recoveries were measured for 13 components in a mixture containing phenols, polynuclear aromatic hydrocarbons(PAH), primary aromatic amines (PAA), and azaarenes (AA) representative of the types of compounds found in synfuel materials. The results demonstrated that recoveries of hydrophobic 3 to 5 ring PAA and AA can be dramatically increased by using methanol as a cosolvent. The modified procedure is highly efficient for extraction of larger PAA and AA, and does not lead to emulsions when extracting samples of coal-derived materials. 2 figures, 2 tables.

Size exclusion chromatography for the unambiguous detection of aliphatics in fractions from petroleum vacuum residues, coal liquids, and standard materials, in the presence of aromatics  

SciTech Connect

A method has been developed using size exclusion chromatography (SEC) in heptane eluent that can detect aliphatics unambiguously without fractionation to remove aromatics. Spherical molecules such as colloidal silicas elute at the exclusion limit, while alkanes up to C{sub 50} elute through the porosity of the column. Detection of aliphatics was defined by use of an evaporative light scattering (ELS) detector with the simultaneous absence of UV absorbance at 300 nm. Alkanes smaller than C{sub 12} were not detected because the conditions of operation of the ELS caused their evaporation. All aromatics eluted after the permeation limit of about 25 min and were not detected until well after 45 min by their UV absorbance. The SEC method was applied to petroleum vacuum residues and coal liquids, and their fractions were soluble in pentane or heptane. High-temperature (HT) GC-MS confirmed the presence of alkanes in the pentane- and heptane-soluble fractions of petroleum vacuum residues, but did not elute any of the aromatics known to be present from SEC. Alkanes were examined in pentane-soluble fractions of a coal digest and a low-temperature coal tar; alkanes up to C{sub 40} were detected in the low-temperature tar and, although present in the digest, were masked by aromatics. No alkanes were detected by either SEC or HT GC-MS in fractions from a coal tar pitch. Aromatics in coal liquids and one petroleum residue were also examined by SEC using NMP as eluent and by UV fluorescence spectroscopy. The SEC method will find application to pentane- and heptane-soluble fractions of petroleum liquids and coal liquids where the alkanes are concentrated relative to the more abundant aromatics. 43 refs., 10 figs., 2 tabs.

Device for aqueous detection of nitro-aromatic compounds  

DOE Patents (OSTI)

This invention relates to a compact and portable detection apparatus for nitro-aromatic based chemical compounds, such as nitrotoluenes, dinitrotoluenes, and trinitrotoluene (TNT). The apparatus is based upon the use of fiber optics using filtered light. The preferred process of the invention relies upon a reflective chemical sensor and optical and electronic components to monitor a decrease in fluorescence when the nitro-aromatic molecules in aqueous solution combine and react with a fluorescent polycyclic aromatic compound. 4 figures.

Stuttering Min oscillations within E. coli bacteria: a stochastic polymerization model  

E-Print Network (OSTI)

We have developed a 3D off-lattice stochastic polymerization model to study subcellular oscillation of Min proteins in the bacteria Escherichia coli, and used it to investigate the experimental phenomenon of Min oscillation stuttering. Stuttering was affected by the rate of immediate rebinding of MinE released from depolymerizing filament tips (processivity), protection of depolymerizing filament tips from MinD binding, and fragmentation of MinD filaments due to MinE. Each of processivity, protection, and fragmentation reduces stuttering, speeds oscillations, and reduces MinD filament lengths. Neither processivity or tip-protection were, on their own, sufficient to produce fast stutter-free oscillations. While filament fragmentation could, on its own, lead to fast oscillations with infrequent stuttering; high levels of fragmentation degraded oscillations. The infrequent stuttering observed in standard Min oscillations are consistent with short filaments of MinD, while we expect that mutants that exhibit highe...

Aromatics oxidation and soot formation in flames  

SciTech Connect

This project is concerned with the kinetics and mechanisms of aromatics oxidation and soot and fullerenes formation in flames. The scope includes detailed measurements of profiles of stable and radical species concentrations in low-pressure one-dimensional premixed flames. Intermediate species identifications and mole fractions, fluxes, and net reaction rates calculated from the measured profiles are used to test postulated reaction mechanisms. Particular objectives are to identify and to determine or confirm rate constants for the main benzene oxidation reactions in flames, and to characterize fullerenes and their formation mechanisms and kinetics.

Emission of polycyclic aromatic hydrocarbons in China  

SciTech Connect

Emission of 16 polycyclic aromatic hydrocarbons (PAHs) listed as U.S. Environmental Protection Agency (U.S. EPA) priority pollutants from major sources in China were compiled. Geographical distribution and temporal change of the PAH emission, as well as emission profiles, are discussed. It was estimated that the total PAH emission in China was 25,300 tons in 2003. The emission profile featured a relatively higher portion of high molecular weight (HMW) species with carcinogenic potential due to large contributions of domestic coal and coking industry. Among various sources, biomass burning, domestic coal combustion, and the coking industry contributed 60%, 20%, and 16% of the total emission, respectively. Total emission, emission density, emission intensity, and emission per capita showed geographical variations. In general, the southeastern provinces were characterized by higher emission density, while those in western and northern China featured higher emission intensity and population-normalized emission. Although energy consumption in China went up continuously during the past two decades, annual emission of PAHs fluctuated depending on the amount of domestic coal consumption, coke production, and the efficiency of energy utilization. 47 refs., 6 figs.

Discrete and Continuous Min-Energy Schedules for Variable Voltage Processors

. A theoretical model for min-energy job scheduling was first proposed a decade ago, and it was shown that for any convex energy function, the min-energy schedule for a set of n jobs has a unique characterization/speed), it saves energy to execute jobs as slowly as possible while still satisfying all timing constraints

However an entry like "text 1234" does not give a warning. I think it should as we are trying to prevent users from writing "less than X", "greater than Y", etc. and follow the intention of the "Max kWh" field. Also there should be a warning if the number of "Max kWh" fields with values is not correct--it should be one less than the number of charge fields with values. There should also be a warning if the "Max kWh" fields do not increase from top to bottom. These checks on input would save lots of trouble when using json files for

The mid-infrared spectra of neutral homogeneous polycyclic aromatic hydrocarbon (PAH) clusters have been computed using density functional theory including an empirical correction for dispersion. The C-H out-of-plane bending modes are redshifted for all the clusters considered in this work. The magnitude of the redshift and the peak broadening are dependent on PAH size, shape, and on the PAH arrangement in the cluster.

A note on the generalized min-sum set cover problem  

Science Journals Connector (OSTI)

In this paper, we consider the generalized min-sum set cover problem, introduced by Azar, Gamzu, and Yin (STOC 2009). Bansal, Gupta, and Krishnaswamy (SODA 2010) give a 485-approximation algorithm for the problem. We are able to alter their algorithm and analysis to obtain a 28-approximation algorithm, improving the performance guarantee by an order of magnitude. We use concepts from ? -point scheduling to obtain our improvements.

Method of upgrading oils containing hydroxyaromatic hydrocarbon compounds to highly aromatic gasoline  

DOE Patents (OSTI)

The present invention is a multi-stepped method of converting an oil which is produced by various biomass and coal conversion processes and contains primarily single and multiple ring hydroxyaromatic hydrocarbon compounds to highly aromatic gasoline. The single and multiple ring hydroxyaromatic hydrocarbon compounds in a raw oil material are first deoxygenated to produce a deoxygenated oil material containing single and multiple ring aromatic compounds. Then, water is removed from the deoxygenated oil material. The next step is distillation to remove the single ring aromatic compounds as gasoline. In the third step, the multiple ring aromatics remaining in the deoxygenated oil material are cracked in the presence of hydrogen to produce a cracked oil material containing single ring aromatic compounds. Finally, the cracked oil material is then distilled to remove the single ring aromatics as gasoline.

ARM Energy Balance Bowen Ratio (EBBR) station: surf. heat flux and related data, 30-min  

DOE Data Explorer (OSTI)

The Energy Balance Bowen Ratio (EBBR) system produces 30-min estimates of the vertical fluxes of sensible and latent heat at the local surface. Flux estimates are calculated from observations of net radiation, soil surface heat flux, and the vertical gradients of temperature and relative humidity. Meteorological data collected by the EBBR are used to calculate bulk aerodynamic fluxes, which are used in the Bulk Aerodynamic Technique (BA) EBBR value-added product (VAP) to replace sunrise and sunset spikes in the flux data. A unique aspect of the system is the automatic exchange mechanism (AEM), which helps to reduce errors from instrument offset drift.

Neutron-induced fission of the 26 min U235 isomer  

Science Journals Connector (OSTI)

We have measured the neutron-induced-fission cross section of the U235 isomer with cold and with thermal neutrons. Because of its short half-life (26 min), preparation of an adequate isomeric target is the major difficulty. A simple and easy-to-operate technique has been developed. The cross-section ratio of isomer to ground state is measured to be 1.610.44 and 2.470.45 for the cold and the thermal neutrons, respectively.

LARGE ABUNDANCES OF POLYCYCLIC AROMATIC HYDROCARBONS IN TITAN'S UPPER ATMOSPHERE  

SciTech Connect

In this paper, we analyze the strong unidentified emission near 3.28 {mu}m in Titan's upper daytime atmosphere recently discovered by Dinelli et al. We have studied it by using the NASA Ames PAH IR Spectroscopic Database. The polycyclic aromatic hydrocarbons (PAHs), after absorbing UV solar radiation, are able to emit strongly near 3.3 {mu}m. By using current models for the redistribution of the absorbed UV energy, we have explained the observed spectral feature and have derived the vertical distribution of PAH abundances in Titan's upper atmosphere. PAHs have been found to be present in large concentrations, about (2-3) Multiplication-Sign 10{sup 4} particles cm{sup -3}. The identified PAHs have 9-96 carbons, with a concentration-weighted average of 34 carbons. The mean mass is {approx}430 u; the mean area is about 0.53 nm{sup 2}; they are formed by 10-11 rings on average, and about one-third of them contain nitrogen atoms. Recently, benzene together with light aromatic species as well as small concentrations of heavy positive and negative ions have been detected in Titan's upper atmosphere. We suggest that the large concentrations of PAHs found here are the neutral counterpart of those positive and negative ions, which hence supports the theory that the origin of Titan main haze layer is located in the upper atmosphere.

Mutagenicity of photochemically-transformed polycyclic aromatic amines  

SciTech Connect

Polycyclic aromatic amines (PAA) constitute a class of suspect genotoxic chemicals found in certain energy-related complex organic mixtures. A variety of studies are reported on the photochemical transformation (oxidation) of polycyclic aromatic amines and the increase in genotoxicity of the resulting complex mixtures of radiation-generated products. Biological endpoints of cytotoxicity and mutagenicity were measured in the Ames/Salmonella standard-plate assay. Chemical fractionation and identification of various photoproducts was accomplished with h.p.l.c., uv and ir spectroscopic and mass spectrometric techniques. The benchmark PAA in these studies was aminofluorene (2-AF). Photooxidation of 2-AF can occur at both the exocyclic nitrogen and certain ring positions resulting in the formation of direct-acting and potent bacterial mutagens, including 2-nitrosofluorene, 2-nitrofluorene, and 2-nitrofluoren-9-one. UVA-irradiated 2-AF solutions also contain promutagenic compounds, i.e., is 2-aminofluoren-9-one. These results support the hypothesis that the critical step in the activation of major, identified direct-acting mutagenic 2-AF photoproducts is their reduction by bacterial nitroreductase enzymes to reactive hydroxylamines. Photochemical oxidation is an alternative mechanism of transforming PAA into direct-acting genotoxins. 24 refs., 5 figs.

Polynuclear aromatic hydrocarbons (PAHs) in fish from the Arabian Gulf  

SciTech Connect

Emphasis has been placed upon the identification and qualification of compounds with potential adverse health effects on humans. Prominent among this group are polynuclear aromatic hydrocarbons (PAHs), several of which are known or suspected carcinogens. PAHs enter the marine environment from a variety of sources including petroleum pollution, industrial and domestic effluents, atmospheric particles, and biosynthesis by plants and microorganisms. Although one-third of the world's oil is produced around the Arabian Gulf, no detailed analysis have been conducted to determine PAHs in this region. Nevertheless, numerous investigations have shown the ability of marine organisms including fish to accumulation PAHs from solution or dispersion in seawater. When fish are harvested, a human health hazard may result. In the present communication, high performance liquid chromatography (HPLC) was used to identify and measure sixteen PAHs priority pollutants issued by US Environmental Protection Agency (EPA) in fourteen species of commercially significant fish from the NW Arabian Gulf.

Distribution of polycyclic aromatic hydrocarbons (PAH's) in marsh sediments, Iraq  

SciTech Connect

Recently there has been a growing concern in the release of harmful organics into the environment. Carcinogenic polycyclic aromatic hydrocarbons (PAH's) are a class of compounds of interset due to their possible harmful effects to man as well as organisms. Anthropogenic PAH's may reach aquatic environment as a result of both industrial and domestic effluents, deposition of airborne particles, surface runoff and oil spillage. Having a relatively low water solubility and high affinity to sorb to the suspended particulate matter, most of the PAH's introduced to the aquatic environment tend to accumulate in bottom sediments. Sedimentary PAH's may thus provide a record of the input and history of these pollutants. Consequently, the distribution of PAH's in aquatic sediments have received considerable attention. The purpose of the present work was to establish the distribution of PAH's in the sediments of the marsh region located in southern Iraq.

Gamma-Ray Studies on the Decay of 2.41-min Ag108  

Science Journals Connector (OSTI)

?-ray singles and coincidence measurements following the decay of 2.41-min Ag108 have been performed with Ge(Li) and NaI(Tl) detectors. A total of 13 ? rays have been assigned to Ag108 decay and their energies and intensities have been measured accurately. From the coincidence measurements and energy-sum relationships 12 ? rays have been fitted into six excited states of Pd108 with the following energies in keV and spins: 433.96, 2+; 931.09, 2+; 1052.82, 0+; 1314.22, 0+; 1441.16, 2+; and 1539.97, 1, 2. The first excited 2+ state of Cd108 at 632.98 keV is also populated by the ? decay of Ag108. The spins of the 1052.82- and 1314.22-keV levels were determined uniquely as 0 from the NaI(Tl)-Ge(Li) directional-correlation measurements. These data also yield a spin of 2 for the 1441.16-keV level and E2+?2%M1 multipolarity for the 1007.22-keV transition. A discussion of the Pd108 levels within the vibrational framework is presented.

Noncovalent ????? interaction between graphene and aromatic molecule: Structure, energy, and nature  

SciTech Connect

Noncovalent ????? interactions between graphene and aromatic molecules have been studied by using density functional theory with empirical dispersion correction (?B97X-D) combined with zeroth-order symmetry adapted perturbation theory (SAPT0). Excellent agreement of the interaction energies computed by means of ?B97X-D and spin component scaled (SCS) SAPT0 methods, respectively, shows great promise for the two methods in the study of the adsorption of aromatic molecules on graphene. The other important finding in this study is that, according to SCS-SAPT0 analyses, ????? interactions between graphene and aromatic molecules are largely dependent on both dispersion and electrostatic type interactions. It is also noticed that ????? interactions become stronger and more dispersive (less electrostatic) upon substitution of the very electronegative fluorine atoms onto the aromatic molecules.

Polycyclic aromatic hydrocarbons and fatal ischemic heart disease  

SciTech Connect

Several toxicologic and epidemiologic studies have produced evidence that occupational exposure to polycyclic aromatic hydrocarbons (PAH) is a risk factor for ischemic heart disease (IHD). However, a clear exposure-response relation has not been demonstrated. We studied a relation between exposure to PAH and mortality from IHD (418 cases) in a cohort of 12,367 male asphalt workers from Denmark, Finland, France, Germany, Israel, The Netherlands and Norway. Exposures to benzo(a)pyrene were assessed quantitatively using measurement-driven exposure models. Exposure to coal tar was assessed in a semiquantitative manner on the basis of information supplied by company representatives. We carried out sensitivity analyses to assess potential confounding by tobacco smoking. Both cumulative and average exposure indices for benzo(a)pyrene were positively associated with mortality from IHD. The highest relative risk for fatal IHD was observed for average benzo(a)pyrene exposures of 273 ng/m{sup 3} or higher, for which the relative risk was 1.64(95% confidence interval = 1.13-2.38). Similar results were obtained for coal tar exposure. Sensitivity analysis indicated that even in a realistic scenario of confounding by smoking, we would observe approximately 20% to 40% excess risk in IHD in the highest PAH-exposure categories. Our results lend support to the hypothesis that occupational PAH exposure causes fatal IHD and demonstrate a consistent exposure-response relation for this association.

Although PAHs can be emitted to the environment as a result of natural combustion processes (e.g., forest fires and volcanoes), human activities are believed to dominate global PAH emissions, because high atmospheric concentrations of PAHs are usually observed in urban and industrial areas where vehicle traffic, aluminum smelting, residential heating, and other activities emit PAHs into the atmosphere (4, 5). ... One of the earliest approaches to describing the G/P partitioning equilibrium of PAHs, known as the Junge?Pankow model, relates ? to PL using the following: The parameter A in this equation is sometimes interpreted as the product of two terms c and ?. ? is the surface area of particles in a unit volume of air (cm2cm-3) and c (Pacm) is a substance-specific factor depending on ambient temper ature, compound, sorption sites, and the heats of desorption from surface and vaporization from the liquid compound (7, 10, 14). ...

Environmental diagnostic analysis of ground water bacteria and their involvement in utilization of aromatic compounds  

SciTech Connect

The objective of this study was to examine the hypothesis that select functional groups of bacteria from pristine sites have an innate ability to degrade synthetic aromatics that often contaminate groundwater environments,due to exposure to naturally occurring recalcitrant aromatics in their environment. This study demonstrates that subsurface microbial communities are capable of utilizing lignin and humic acid breakdown products. Utilizers of these compounds were found to be present in most all the wells tested. Even the deepest aquifer tested had utilizers present for all six of the aromatics tested. Highest counts for the aromatics tested were observed with the naturally occurring breakdown products of either lignin or humic acid. Carboxylic acids were found to be an important sole carbon source for groundwater bacteria possibly explained by the fact that they are produced by the oxidative cleavage of aromatic ring structures. The carbohydrate sole carbon sources that demonstrated the greatest densities were ones commonly associated with humics. This study indicates that utilization of naturally occurring aromatic compounds in the subsurface is an important nutritional source for groundwater bacteria. In addition, it suggests that adaptation to naturally occurring recalcitrant substrates is the origin of degradative pathways for xenobiotic compounds with analogous structure. This work has important implications for in situ bioremediation as a method of environmental cleanup.

Sorption characteristics of polycyclic aromatic hydrocarbons in aluminum smelter residues  

SciTech Connect

High temperature carbon oxidation in primary aluminum smelters results in the release of polycyclic aromatic hydrocarbons (PAH) into the environment. The main source of PAH are the anodes, which are composed of petroleum coke (black carbon, BC) and coal tar pitch. To elucidate the dominant carbonaceous phase controlling the environmental fate of PAH in aluminum smelter residues (coke BC and/or coal tar), the sorptive behavior of PAHs has been determined, using passive samplers and infinite-sink desorption methods. Samples directly from the wet scrubber were studied as well as ones from an adjacent 20-year old storage lagoon and roof dust from the smelter. Carbon-normalized distribution coefficients of native PAHs were 2 orders of magnitude higher than expected based on amorphous organic carbon (AOC)/water partitioning, which is in the same order of magnitude as reported literature values for soots and charcoals. Sorption isotherms of laboratory-spiked deuterated phenanthrene showed strong (about 100 times stronger than AOC) but nonetheless linear sorption in both fresh and aged aluminum smelter residues. The absence of nonlinear behavior typical for adsorption to BC indicates that PAH sorption in aluminum smelter residues is dominated by absorption into the semi-solid coal tar pitch matrix. Desorption experiments using Tenax showed that fresh smelter residues had a relatively large rapidly desorbing fraction of PAH (35-50%), whereas this fraction was strongly reduced (11-16%) in the lagoon and roof dust material. Weathering of the coal tar residue and/or redistribution of PAH between coal tar and BC phases could explain the reduced availability in aged samples. 38 refs., 5 figs., 1 tab.

Kinetics and mechanisms of reactions involving small aromatic reactive intermediates  

SciTech Connect

Small aromatic radicals such as C{sub 6}H{sub 5}, C{sub 6}H{sub 5}O and C{sub 6}H{sub 4} are key prototype species of their homologs. C{sub 6}H{sub 5} and its oxidation product, C{sub 6}H{sub 5}O are believed to be important intermediates which play a pivotal role in hydrocarbon combustion, particularly with regard to soot formation. Despite their fundamental importance, experimental data on the reaction mechanisms and reactivities of these species are very limited. For C{sub 6}H{sub 5}, most kinetic data except its reactions with NO and NO{sub 2}, were obtained by relative rate measurements. For C{sub 6}H{sub 5}O, the authors have earlier measured its fragmentation reaction producing C{sub 5}H{sub 5} + CO in shock waves. For C{sub 6}H{sub 4}, the only rate constant measured in the gas phase is its recombination rate at room temperature. The authors have proposed to investigate systematically the kinetics and mechanisms of this important class of molecules using two parallel laser diagnostic techniques--laser resonance absorption (LRA) and resonance enhanced multiphoton ionization mass spectrometry (REMPI/MS). In the past two years, study has been focused on the development of a new multipass adsorption technique--the {open_quotes}cavity-ring-down{close_quotes} technique for kinetic applications. The preliminary results of this study appear to be quite good and the sensitivity of the technique is at least comparable to that of the laser-induced fluorescence method.

Process for removing halogenated aliphatic and aromatic compounds from petroleum products  

DOE Patents (OSTI)

A process is described for removing halogenated aliphatic and aromatic compounds, e.g., polychlorinated biphenyls, from petroleum products by solvent extraction. The halogenated aliphatic and aromatic compounds are extracted from a petroleum product into a polar solvent by contacting the petroleum product with the polar solvent. The polar solvent is characterized by a high solubility for the extracted halogenated aliphatic and aromatic compounds, a low solubility for the petroleum product and considerable solvent power for polyhydroxy compound. The preferred polar solvent is dimethylformamide. A miscible compound, such as, water or a polyhydroxy compound, is added to the polar extraction solvent to increase the polarity of the polar extraction solvent. The halogenated aliphatic and aromatic compounds are extracted from the highly-polarized mixture of water or polyhydroxy compound and polar extraction solvent into a low polar or nonpolar solvent by contacting the water or polyhydroxy compound-polar solvent mixture with the low polar or nonpolar solvent. The halogenated aliphatic and aromatic compounds and the low polar or nonpolar solvent are separated by physical means, e.g., vacuum evaporation. The polar and nonpolar solvents are recovered from recycling. The process can easily be designed for continuous operation. Advantages of the process include that the polar solvent and a major portion of the nonpolar solvent can be recycled, the petroleum products are reclaimable and the cost for disposing of waste containing polychlorinated biphenyls is significantly reduced. 1 fig.

Abstract Coatings with a high amount of MAX phase were obtained onto Ti substrate using the pulsed electrospark deposition (PED) technique and Cr2AlC electrode material (??). The structure and phase formation of the coatings generated at different modes were studied. It was found, that a layer of titanium carbide was formed during the initial stage of the deposition at the interface as a result of chemical reaction between Cr2AlC electrode and Ti substrate which further acts as a diffusion barrier.

The equations required for the calculations have been derived based on the assignment of the overlapped 1H NMR spectra of the samples with particular emphasis on signals from naphthenes and iso-paraffins. The 1H NMR results have been compared with those obtained from GC method. The absolute standard deviations between the NMR and GC methods are1.7 and 2.1% for total aromatics and naphthenes, respectively.

The electronic structure and optical conductivities of 20 so-called MAX phases Ti3AC2 (A = Al, Si, Ge), Ti2AC (A = Al, Ga, In, Si, Ge, Sn, P, As, S), Ti2AlN, M2AlC (M = V, Nb, Cr), and Tan+1AlCn (n = 1 to 4) are studied using the first-principles orthogonalized linear combination of atomic orbitals (OLCAO) method. The calculated results include total and partial density of states, effective charge on each atom, and quantitative bond order values. Also calculated are directionally resolved interband optical conductivities. By analyzing such results regarding these phases (that have different atomic compositions and layered structures) several important features on structural stability and electrical conductivities are identified and compared with experimental data. We confirm the trend of increasing N(Ef) (total density of states at the Fermi level Ef) as the number of valence electrons of the composing elements increases. The local feature of total density of states (TDOS) near Ef is used to predict structural stability. The calculated effective charge on each atom shows that the M (transition-metal) atoms always lose charge to the X (C or N) atoms, whereas the A-group atoms mostly gain charge but some lose charge. Bond order values are obtained and critically analyzed for all types of interatomic bonds in all the 20 MAX phases.

A new carbon-13 method for determining aromatic, naphthenic and paraffinic carbon  

SciTech Connect

The determination of the relative percentages of aromatic, naphthenic and paraffinic carbon in samples of natural origin is important for many petroleum related studies including processing, geological studies, and certain product specifications. The normal method is the n-d-M method which requires the measurement of refractive index, density and molecular weight and a ternary correlation diagram to obtain the relative carbon percentages. It is difficult or inconvenient to make n-d-M measurements of very heavy products and the presence of significant amounts of polar materials makes n-d-M results inaccurate. The average molecular parameters determinable by a number of NMR techniques are directly or indirectly related to the percentage of various carbon types present in the mixture. Unfortunately, all the standard techniques we have examined have some built-in assumption which does not allow the accurate calculation of relative carbon percentages. For example, any proton technique applicable to aromatic fractions will give potentially low values for naphthenic carbon because naphthenic carbon is normally determined from the ..beta..-CH/sub 2/ region of tetralin-type structures (1.65-1.9 ppm). This is a very specific kind of naphthenic structure and to the extent that more than one saturate ring is asymmetrically condensed to the aromatic ring or that the saturate rings are not directly condensed to the aromatic rings, the method will fail.

Aromatization of propane: Techno-economic analysis by multiscale kinetics-to-process simulation  

Science Journals Connector (OSTI)

Abstract This paper addresses the techno-economic analysis of the propane aromatization process, by adopting a novel kinetics-to-process approach. The recent interest in this technological route derives from the development of new third generation biorefinery concepts, in which, algal oil is subjected to catalytic hydrodeoxygenation processes for the production of (Hydrotreated Renewable Jet) HRJ fuels. Beside biofuels, co-production of large amounts of propane is observed, which can be upgraded by a catalytic conversion to aromatics on zeolites. Kinetic studies of propane aromatization over H-ZSM-5 zeolite in a wide range of conversions are reported in the literature. Based on these results, a general kinetic model of propane aromatization has been developed. The revised kinetic scheme is then embedded in a process simulation, performed with the commercial code SimSci PRO/II by Schneider Electric. Basing on the process simulation and on available price assessments, a techno-economic analysis has been performed to show limits as well as potentialities of the proposed layout.

Cd doping effects in the heavy-fermion compounds Ce2MIn8 (M=Rh and Ir)  

Science Journals Connector (OSTI)

Low-temperature magnetic properties of Cd-doped Ce2MIn8 (M=Rh and Ir) single crystals are investigated. Experiments of temperature-dependent magnetic-susceptibility, heat-capacity, and electrical-resistivity measurements revealed that Cd doping enhances the antiferromagnetic (AFM) ordering temperature from TN=2.8?K (x=0) to TN=4.8?K (x=0.21) for Ce2RhIn8?xCdx and induces long-range AFM ordering with TN=3.8?K (x=0.21) for Ce2IrIn8?xCdx. Additionally, x-ray and neutron magnetic scattering studies showed that Cd-doped samples present below TN a commensurate antiferromagnetic structure with a propagation vector ??=(12,12,0). The resolved magnetic structures for both compounds indicate that the Cd doping tends to rotate the direction of the ordered magnetic moments toward the ab plane. This result suggests that the Cd doping affects the Ce3+ ground-state single-ion anisotropy modifying the crystalline electrical field (CEF) parameters at the Ce3+ site. Indications of CEF evolution induced by Cd doping were also found in the electrical-resistivity measurements. Comparisons between our results and the general effects of Cd doping on the related compounds CeMIn5 (M=Co, Rh, and Ir) confirms the claims that the Cd doping induced electronic tuning is the main effect favoring AFM ordering in these compounds.

Chemometric optimization of dispersive suspended microextraction followed by gas chromatographymass spectrometry for the determination of polycyclic aromatic hydrocarbons in natural waters  

Science Journals Connector (OSTI)

Abstract A dispersive suspended microextraction (DSME) method coupled with gas chromatographymass spectrometry (GCMS) was developed and validated for the simultaneous determination of ten polycyclic aromatic hydrocarbons in real water samples. The optimization of the method was achieved with a 274 PlackettBurman design, while the significant factors were optimized using a central composite design (CCD). The parameters that were studied included the sample volume, organic solvent volume, extraction time, restoration time and organic solvent. The optimum experimental conditions for the proposed method comprised 4.3mL of the water sample, 93?L of toluene as the extraction solvent, a 104-s extraction time and a 10-min restoration time. The recoveries varied from 70 to 111%. Chrysene was the least recovered compound, while anthracene displayed the highest extraction efficiency. The analytical method (DSME) was shown to be linear (R2>0.993) over the studied range of concentrations, exhibiting satisfactory precision (RSD%<10.6%) and reaching limits of detection between 8 and 46ngL?1.

A one-dimensional Lattice Boltzmann method for modeling the dynamic pole-to-pole oscillations of Min proteins for determining the position of the midcell division plane  

E-Print Network (OSTI)

Determining the middle of the bacteria cell and the proper placement of the septum is essential to the division of the bacterial cell. In E. coli, this process depends on the proteins MinC, MinD, and MinE. Here, the Lattice Boltzmann method (LBM) is used to study the dynamics of the oscillations of the min proteins from pole to pole. This determines the midcell division plane at the cellular level. The LBM is applied to the set of the deterministic reaction diffusion equations proposed by Howard et. al. [1] to describe the dynamics of the Min proteins. The LBM results are in good agreement with those of Howard et al, and agree qualitatively with the experimental results. Our good results indicate that the LBM can be an alternative computational tool for simulating problems dealing with complex biological system which are described by the reaction-diffusion equations.

Boride-based nano-laminates with MAX-phase-like behaviour  

SciTech Connect

MAX-phases being usually composed of transition metals, group A elements and carbon/nitrogen are considered interesting materials for many applications because of their tremendous bulk modulus, 'reversible' plasticity, and machinability. This is mainly due to their unique kind of bonding comprising covalent, ionic as well as metallic bonds providing 'easy' planes of rupture and deformability due to the layered crystal structures. In transition metal boride systems, similar types of bonding are available. In particular the W{sub 2}B{sub 5}-structure type and its stacking variations allow the synthesis of strongly layered crystal structures exhibiting unique delamination phenomena. The paper presents ab initio calculations showing the similarities of bonding between the ternary carbides and the corresponding ternary or quaternary borides. Formation of boride-based nano-laminates from auxiliary liquid phases, from the melt as well as during sintering and precipitation from supersaturated solid solutions will be discussed by means of SEM and TEM studies. The role of impurities weakening the interlayer bonding will be addressed in particular. The pronounced cleavage parallel to the basal plane gives rise for crack deflection and pull-out mechanisms if the laminates are dispersed in brittle matrices such as boron carbide, silicon carbide or other transition metal borides. - Graphical abstract: Some transition metal borides crystallise in a layered structure of alternating stacks of metal and boron atoms giving rise for strongly anisotropic properties. Their preferred cleavage parallel and the deformability perpendicular to the basal plan are similar to the peculiar mechanical behaviour recently described for MAX-phases. Ab initio calculations of the crystal structure prove the weak bonds between the layers for a variety of borides which can be used to reinforce ceramic materials on a nano-scale level.

Polycyclic aromatic hydrocarbons (PAH) in top soil, leachate and groundwater from Ruseifa solid waste landfill, Jordan  

Science Journals Connector (OSTI)

The distribution profiles and pathways of polynuclear aromatic hydrocarbons in the surroundings of Ruseifa landfill area in Jordan were investigated for surface sediments, leachate, and groundwater. The total concentration of 16 polycyclic aromatic hydrocarbons (PAHs) in sediments ranged from 286 to 1704 ppm with an average value of 751 ppm. Meanwhile, concentrations of PAH in groundwater ranged between 7.1 and 12.6 ppm with an average value of 9.1 ppm. The PAH in leachate varied between 0.10 and 0.40 with an average value of 0.29 ppm. The overall PAH distribution profiles appeared to be similar for leachate and groundwater dominated by 2??3 rings system molecules. While, the sediments profile was dominated by 4??6 rings system molecules which indicated the loss of low molecular weight compounds of PAH and accumulation of higher molecular weight of PAH under prevailing semiarid and hot climatic conditions.

An ab initio study on compressibility of Al-containing MAX-phase carbides  

SciTech Connect

The compressibility of Al-containing MAX carbides was investigated in details using first-principle calculations based on density functional theory. The bond stiffness and bond angle as a function of pressure were examined. The M-Al bond stiffness is about 1/31/2 of M-C bond stiffness. The M-C bond close to Al atoms has the highest bond stiffness in M{sub 3}AlC{sub 2} and M{sub 4}AlC{sub 3} phases, with the similar bond stiffness of the other two bonds in the latter. Generally, the bond stiffness of the strongest M-C bond increases with increasing VEC (Valence Electron Concentration), which also affects the bond stiffness of other bonds. Of most importance, the bulk moduli are 0.256 of the mean bond stiffness for three series. With increasing pressure, M-Al bond angle increases, but M-C bond angles decreases, which indicates that M-Al and M-C bonds shift towards basal plane and along c-axis, respectively. As a result, the compressibility becomes more difficult along c-axis than a-axis. Some abnormal phenomena in the compressibility of Al-containing M{sub n+1}AlX{sub n} phases with VEC?=?6 are attributed to the thermodynamical instability of these compounds.

Process for removing halogenated aliphatic and aromatic compounds from petroleum products. [Polychlorinated biphenyls; methylene chloride; perchloroethylene; trichlorofluoroethane; trichloroethylene; chlorobenzene  

DOE Patents (OSTI)

A process for removing halogenated aliphatic and aromatic compounds, e.g., polychlorinated biphenyls, from petroleum products by solvent extraction. The halogenated aliphatic and aromatic compounds are extracted from a petroleum product into a polar solvent by contracting the petroleum product with the polar solvent. The polar solvent is characterized by a high solubility for the extracted halogenated aliphatic and aromatic compounds, a low solubility for the petroleum product and considerable solvent power for polyhydroxy compound. The preferred polar solvent is dimethylformamide. A miscible polyhydroxy compound, such as, water, is added to the polar extraction solvent to increase the polarity of the polar extraction solvent. The halogenated aliphatic and aromatic compounds are extracted from the highly-polarized mixture of polyhydroxy compound and polar extraction solvent into a low polar or nonpolar solvent by contacting the polyhydroxy compound-polar solvent mixture with the low polar or nonpolar solvent. The halogenated aliphatic and aromatic compounds in the low polar or nonpolar solvent by physical means, e.g., vacuum evaporation. The polar and nonpolar solvents are recovered for recycling. The process can easily be designed for continuous operation. Advantages of the process include that the polar solvent and a major portion of the nonpolar solvent can be recycled, the petroleum products are reclaimable and the cost for disposing of waste containing polychlorinated biphenyls is significantly reduced. 2 tables.

A study on the coagulation of polycyclic aromatic hydrocarbon clusters to determine their collision efficiency  

SciTech Connect

This paper presents a theoretical study on the physical interaction between polycyclic aromatic hydrocarbons (PAHs) and their clusters of different sizes in laminar premixed flames. Two models are employed for this study: a detailed PAH growth model, referred to as the kinetic Monte Carlo - aromatic site (KMC-ARS) model [Raj et al., Combust. Flame 156 (2009) 896-913]; and a multivariate PAH population balance model, referred to as the PAH - primary particle (PAH-PP) model. Both the models are solved by kinetic Monte Carlo methods. PAH mass spectra are generated using the PAH-PP model, and compared to the experimentally observed spectra for a laminar premixed ethylene flame. The position of the maxima of PAH dimers in the spectra and their concentrations are found to depend strongly on the collision efficiency of PAH coagulation. The variation in the collision efficiency with various flame and PAH parameters is studied to determine the factors on which it may depend. A correlation for the collision efficiency is proposed by comparing the computed and the observed spectra for an ethylene flame. With this correlation, a good agreement between the computed and the observed spectra for a number of laminar premixed ethylene flames is found. (author)

Biomarker sensitivity for polynuclear and halogenated aromatic hydrocarbon contamination in fish species from Galveston Bay  

SciTech Connect

The Galveston Bay estuary exhibits a contamination gradient for polynuclear aromatic hydrocarbons (PAHs) and halogenated aromatic hydrocarbons, which is useful for comparing biomarker response sensitivity in fish taken from different bay locations. Two fish species, hardhead catfish (Arius felis) and Atlantic croaker (Micropogon undulatus), were collected from four stations where sediment total PAHs ranged from 68 to > 1,000 ng/g. Hardhead catfish showed no consistent CYP1A mediated responses (hepatic ethoxyresorufin-O-deethylase activity (EROD), CYP1A mRNA levels, or CYP1A immunoreactive protein) in the field collected fish or in fish dosed with up to 15 mg/kg benzo(a)pyrene (BaP). Significant differences were seen in field collected hardhead catfish in biliary concentrations of naphthalene, phenanthrene, and BaP metabolites. Conversely, in croakers taken from the same four Galveston Bay locations, there were significant elevations IN EROD and glutathione-S-transferase activities, CYP1A immunoreactive protein, and biliary PAH metabolites at the contaminated stations. These studies suggest that croaker is a good monitoring species especially with respect to induction of CYP1A mediated responses by PAHs. Biliary PAH metabolites and PAH-DNA adducts were sensitive to PAH contamination in both species.

Bolduc, Gabriel Burch, Griffin Hosseinzadeh, and Seth Saltiel Document Number LBNL-4608E Pagination 13 Date Published July 11 Publisher Lawrence Berkeley National Laboratory City Berkeley Abstract This study surveyed the technical potential for efficiency improvements in 150 categories of appliances and equipment representing 33 quads of primary energy use across the US economy in 2010 and (1) documented efficient product designs, (2) identified the most promising cross-cutting strategies, and (3) ranked national energy savings potential by end use. Savings were estimated using a method modeled after US Department of Energy priority-setting reports-simplified versions of the full technical and economic analyses performed for rulemakings. This study demonstrates that large savings are possible by replacing products at the end-of-life with ultra-efficient models that use existing technology. Replacing the 50 top energy-saving end-uses (constituting 30 quads of primary energy consumption in 2010) with today's best-on-market equivalents would save ~200 quads of US primary energy over 30 years (25% of consumption anticipated there from). For the 29 products for maximum feasible savings potential could be estimated, the savings were twice as high. These results demonstrate that pushing ultra-efficient products to market could significantly escalate carbon emission reductions and is a viable strategy for sustaining large emissions reductions through standards. The results of this analysis were used by DOE for new coverage prioritization, to identify key opportunities for product prototyping and market development, and will leverage future standards rulemakings by identifying the full scope of maximum feasible technology options. High leverage products include advances lighting systems, HVAC, and televisions. High leverage technologies include electronic lighting, heat pumps, variable speed motors, and a host of controls-related technologies.

MHUG process for production of low sulfur and low aromatic diesel fuel. [Medium-pressure Hydro UpGrading  

SciTech Connect

A new hydro-upgrading process operated under medium pressure has been developed to reduce the sulfur and the aromatics content in light cycle oil (LCO). Two catalysts were used in series in this technology. The commercial RN-1 catalyst, which is known as having high activity in hydrodenitrogenation, desulfurization and aromatic saturation, was chosen as the first catalyst. The second one was a nickel-tungsten zeolite catalyst, named RT-5, which was developed by RIPP specially for hydrogenolysis of naphthenic and aromatic hydrocarbons. The pilot plant tests showed that high quality diesel oil with aromatics content less than 20 v% and sulfur content less than 0.05 wt% could be produced from various LCO/straight-run-gas-oil (SRGO) blended feedstocks under hydrogen partial pressure of 6.4 MPa. The reaction temperature and overall space velocity (S.V.) varied in the range of 350--380 C and 0.6--1.2 h[sup [minus]1], respectively, depending on the properties of the feedstocks to be processed and the upgrading depth required. Several examples presented also illustrated that this technology could be used to prepare catalytic reforming feedstock as well, which is in urgent need in China. A life test operated in relatively high severity for 3,000 hr. indicated that the catalysts possessed excellent stability. A commercial demonstration unit has been running well since the last Oct 1.

THE NASA AMES POLYCYCLIC AROMATIC HYDROCARBON INFRARED SPECTROSCOPIC DATABASE: THE COMPUTED SPECTRA  

SciTech Connect

The astronomical emission features, formerly known as the unidentified infrared bands, are now commonly ascribed to polycyclic aromatic hydrocarbons (PAHs). The laboratory experiments and computational modeling done at the NASA Ames Research Center to create a collection of PAH IR spectra relevant to test and refine the PAH hypothesis have been assembled into a spectroscopic database. This database now contains over 800 PAH spectra spanning 2-2000 {mu}m (5000-5 cm{sup -1}). These data are now available on the World Wide Web at www.astrochem.org/pahdb. This paper presents an overview of the computational spectra in the database and the tools developed to analyze and interpret astronomical spectra using the database. A description of the online and offline user tools available on the Web site is also presented.

On-line database of the spectral properties of polycyclic aromatic hydrocarbons  

E-Print Network (OSTI)

We present an on-line database of computed molecular properties for a large sample of polycyclic aromatic hydrocarbons (PAHs) in four charge states: -1, 0, +1, and +2. At present our database includes 40 molecules ranging in size from naphthalene and azulene (C10H8) up to circumovalene (C66H20). We performed our calculations in the framework of the density functional theory (DFT) and the time-dependent DFT to obtain the most relevant molecular parameters needed for astrophysical applications. For each molecule in the sample, our database presents in a uniform way the energetic, rotational, vibrational, and electronic properties. It is freely accessible on the web at http://astrochemistry.ca.astro.it/database/ and http://www.cesr.fr/~joblin/database/.

Anisotropy and Size Effects on the Optical Spectra of Polycyclic Aromatic Hydrocarbons  

E-Print Network (OSTI)

The electronic and optical properties of polycyclic aromatic hydrocarbons (PAHs) present a strong dependence on their size and geometry. We tackle this issue by analyzing the spectral features of two prototypical classes of PAHs, belonging to D6h and D2h symmetry point groups and related to coronene as multifunctional seed. While the size variation induces an overall red shift of the spectra and a redistribution of the oscillator strength between the main peaks, a lower molecular symmetry is responsible for the appearance of new optical features. Along with broken molecular orbital degeneracies, optical peaks split and dark states are activated in the low-energy part of the spectrum. Supported by a systematic analysis of the composition and the character of the optical transitions, our results contribute in shedding light to the mechanisms responsible for spectral modifications in the visible and near UV absorption bands of medium-size PAHs.

Extraction agents for the removal of polycyclic aromatic hydrocarbons (PAHs) from soil in soil washing technologies  

Science Journals Connector (OSTI)

Abstract Polycyclic aromatic hydrocarbons (PAHs) in soil have been recognised as a serious health and environmental issue due to their carcinogenic, mutagenic and teratogenic properties. One of the commonly employed soil remediation techniques to clean up such contamination is soil washing or solvent extraction. The main factor which governs the efficiency of this process is the solubility of \\{PAHs\\} in the extraction agent. Past field-scale soil washing treatments for PAH-contaminated soil have mainly employed organic solvents or water which is either toxic and costly or inefficient in removing higher molecular weight PAHs. Thus, the present article aims to provide a review and discussion of the alternative extraction agents that have been studied, including surfactants, biosurfactants, microemulsions, natural surfactants, cyclodextrins, vegetable oil and solution with solid phase particles. These extraction agents have been found to remove \\{PAHs\\} from soil at percentages ranging from 47 to 100% for various PAHs.

Air pollution from a large steel factory: polycyclic aromatic hydrocarbon emissions from coke-oven batteries  

SciTech Connect

A systematic investigation of solid and gaseous atmospheric emissions from some coke-oven batteries of one of Europe's largest integrated steel factory (Taranto, Italy) has been carried out. These emissions, predominantly diffuse, originate from oven leakages, as well as from cyclic operations of coal loading and coke unloading. In air monitoring samples, polycyclic aromatic hydrocarbons (PAHs) were consistently detected at concentrations largely exceeding threshold limit values. By means of PAHs speciation profile and benzo-(a)pyrene (BaP) equivalent dispersion modeling from diffuse sources, the study indicated that serious health risks exist not only in working areas, but also in a densely populated residential district near the factory. 30 refs., 5 figs., 3 tabs.

Distribution and sources of polycyclic aromatic hydrocarbons in surface sediments of the Hormuz strait, Persian Gulf  

Science Journals Connector (OSTI)

Abstract The concentrations of 16 polycyclic aromatic hydrocarbons (PAHs) were determined in the sediment from the Hormuz strait, Persian Gulf. The sum of 16 \\{PAHs\\} (?PAH) concentrations varied from 72.17 to 277.77ngg?1 dry weight, with an average value of 131.2059.29ngg?1 dry weight. An ecological risk assessment of PAHs, indicated that adverse biological effects caused by acenaphthene and acenaphthylene occasionally may take place in the sediment of Hormuz strait. PAH source identification showed that the \\{PAHs\\} in the sediments come from pyrogenic and mixed origin. Based on classification of pollution levels, sediments from Hormuz strait could be considered as low to moderately polluted with PAHs.

Rendering graphene supports hydrophilic with non-covalent aromatic functionalization for transmission electron microscopy  

SciTech Connect

Amorphous carbon films have been routinely used to enhance the preparation of frozen-hydrated samples for transmission electron microscopy (TEM), either in retaining protein concentration, providing mechanical stability or dissipating sample charge. However, strong background signal from the amorphous carbon support obstructs that of the sample, and the insulating properties of thin amorphous carbon films preclude any efficiency in dispersing charge. Graphene addresses the limitations of amorphous carbon. Graphene is a crystalline material with virtually no phase or amplitude contrast and unparalleled, high electrical carrier mobility. However, the hydrophobic properties of graphene have prevented its routine application in Cryo-TEM. This Letter reports a method for rendering graphene TEM supports hydrophilica convenient approach maintaining graphene's structural and electrical properties based on non-covalent, aromatic functionalization.

THE INFRARED SPECTRA OF POLYCYCLIC AROMATIC HYDROCARBONS WITH SOME OR ALL HYDROGEN ATOMS REMOVED  

SciTech Connect

The loss of one hydrogen from C{sub 96}H{sub 24} does not significantly affect the infrared spectra of the neutral, cation, or anion. Excluding a very weak C-C stretching band at 5.1 ?m, the loss of two adjacent duo hydrogens does not significantly affect the spectra compared with the parent. Removing all of the hydrogen atoms significantly increases the intensity of the new C-C stretching band, and, for the cation, shifts it to a longer (5.2 ?m) wavelength. Observations show a feature near 5.25 ?m, which has been attributed to overtone and combination bands from polycyclic aromatic hydrocarbons (PAHs). This current work suggests that dehydrogenated PAHs might also contribute to this band, but its weakness implies that fully dehydrogenated cationic or dicationic species are very rare.

The unusual hydrocarbon emission from the early carbon star HD 100764: The connection between aromatics and aliphatics  

E-Print Network (OSTI)

We have used the Infrared Spectrograph (IRS) on the Spitzer Space Telescope to obtain spectra of HD 100764, an apparently single carbon star with a circumstellar disk. The spectrum shows emission features from polycyclic aromatic hydrocarbons (PAHs) that are shifted to longer wavelengths than normally seen, as characteristic of ``class C'' systems in the classification scheme of Peeters et al. All seven of the known class C PAH sources are illuminated by radiation fields that are cooler than those which typically excite PAH emission features. The observed wavelength shifts are consistent with hydrocarbon mixtures containing both aromatic and aliphatic bonds. We propose that the class C PAH spectra are distinctive because the carbonaceous material has not been subjected to a strong ultraviolet radiation field, allowing relatively fragile aliphatic materials to survive.

Extraction of aromatics from petroleum naphtha reformate by a 1-cyclohexyl-2-pyrrolidone/ethylene carbonate mixed solvent  

SciTech Connect

The phase equilibria for the extraction of aromatics from petroleum naphtha reformate (with a boiling range of 338--403 K) using a mixed solvent of 1-cyclohexyl-2-pyrrolidone (CHP) and ethylene carbonate (EC) have been correlated using the universal function-group activity coefficients model (UNIFAC). The interaction parameters of CHP and EC with different hydrocarbon groups present in the reformate such as CH{sub 2} (paraffinic CH{sub 2}), ACH (aromatic CH), ACCH{sub 2} (aromatic CCH{sub 2}), and each of the two solvents have been fitted to experimental concentrations of three ternary systems that contain these groups. The extraction runs have been carried out at different temperatures, solvent compositions, and solvent-to-feed ratios. Experimental results compared favorably with those predicted from the UNIFAC method. The optimum extraction conditions were determined by calculation of the minimum energy of separation. In this study these conditions were found to be at a mixed solvent composition of 65% EC (by weight) and 35% CHP. The solvent-to-feed ratio was 1.8 on a volume basis, and the extraction temperature was 329 K.

Polycyclic aromatic hydrocarbons (PAHs) in burning and non-burning coal waste piles  

Science Journals Connector (OSTI)

The coal waste material that results from Douro Coalfield exploitation was analyzed by gas chromatography with mass spectrometry (GCMS) for the identification and quantification of the 16 polycyclic aromatic hydrocarbons (PAHs), defined as priority pollutants. It is expected that the organic fraction of the coal waste material contains \\{PAHs\\} from petrogenic origin, and also from pyrolytic origin in burning coal waste piles. The results demonstrate some similarity in the studied samples, being phenanthrene the most abundant PAH followed by fluoranthene and pyrene. A petrogenic contribution of \\{PAHs\\} in unburned samples and a mixture of \\{PAHs\\} from petrogenic and pyrolytic sources in the burning/burnt samples were identified. The lowest values of the sum of the 16 priority \\{PAHs\\} found in burning/burnt samples and the depletion LMW \\{PAHs\\} and greater abundance of HMW \\{PAHs\\} from the unburned coal waste material relatively to the burning/burnt material demonstrate the thermal transformation attributed to the burning process. The potential environmental impact associated with the coal waste piles are related with the release of petrogenic and pyrolytic \\{PAHs\\} in particulate and gaseous forms to soils, sediments, groundwater, surface water, and biodiversity.

A single domain thermophilic xylanase can bind insoluble xylan: evidence for surface aromatic clusters  

Science Journals Connector (OSTI)

A clone expressing xylanase activity in Escherichia coli has been selected from a genomic plasmid library of the thermophilic Bacillus strain D3. Subcloning from the 9-kb insert located the xylanase activity to a 2.7-kb HindII/BamHI fragment. The DNA sequence of this clone revealed an ORF of 367 codons encoding a single domain type-F or family 10 enzyme, which was designated as XynA. Purification of the enzyme following over-expression in E. coli produced an enzyme of 42 kDa with a temperature optimum of 75C which can efficiently bind and hydrolyse insoluble xylan. The pH optimum of the enzyme is 6.5, but it is active over a broad pH range. A homology model of the xylanase has been constructed which reveals a series of surface aromatic residues which form hydrophobic clusters. This unusual structural feature is strikingly similar to the situation observed in the structure determined for the type-G xylanase from the Bacillus D3 strain and may constitute a common evolutionary mechanism imposed on different structural frameworks by which these xylanases may bind potential substrates and exhibit thermostability.

Measurement of polynuclear aromatic hydrocarbon concentrations in the plume of Kuwait oil well fires  

SciTech Connect

Following their retreat from Kuwait during February and March of 1991, the Iraqi Army set fire to over 500 oil wells dispersed throughout the Kuwait oil fields. During the period of sampling from July to August 1991, it was estimated that between 3.29 {times} 10{sup 6} barrels per day of crude oil were combusted. The resulting fires produced several plumes of black and white smoke that coalesced to form a composite ``super`` plume. Because these fires were uncontrolled, significant quantities of organic materials were dispersed into the atmosphere and drifted throughout the Middle East. The organic particulants associated with the plume of the oil well fires had a potential to be rich in polynuclear aromatic hydrocarbon (PAH) compounds. Based on the extreme mutagenic and carcinogenic activities of PAHs found in laboratory testing, a serious health threat to the population of that region potentially existed. Furthermore, the Kuwait oil fire plumes represented a unique opportunity to study the atmospheric chemistry associated with PAHs in the plume. If samples were collected near the plume source and from the plume many kilometers downwind from the source, comparisons could be made to better understand atmospheric reactions associated with particle-bound and gas-phase PAHs. To help answer health-related concerns and to better understand the fate and transport of PAHs in an atmospheric environment, a sampling and analysis program was developed.

Reaction of aromatic compounds and coal-derived liquids with steam over alumina supported nickel catalysts  

SciTech Connect

The objective of this research program has been to explore and define the potential of steam reforming to produce light gases from coal-derived liquids. This was achieved through a study of the reaction of a model aromatic compound and of a coal-derived liquid with steam over an alumina supported nickel catalyst. The reaction of steam with benzene and SRC-II liquids over an alumina supported nickel-catalyst has been investigated in a plug flow reactor. The primary process variables investigated were reactor pressure and temperature, contact time, and steam/carbon ratio. A proposed reaction network was also developed to explain the data obtained in this study. The empirical rate equation for the benzene steam reforming reaction at 973 K, 300 psig, and a steam/carbon ratio of approximately 3 was r/sub C6H6/ = 1.92 x 10 TP/sub C6H6/. The activation energy was 88 KJ/mol, or 21 kcal/mol in the temperature range 748-973 K. A correlation was developed to predict product yields and hydrocarbon conversion over the range of process variables investigated. A second correlation was developed to predict the yields and conversion beyond the range of variables investigated.

POLYCYCLIC AROMATIC HYDROCARBON EMISSION IN THE PROPLYD HST10: WHAT IS THE MECHANISM BEHIND PHOTOEVAPORATION?  

SciTech Connect

Proplyds are photodissociation-region-(PDR)-like cometary cocoons around young stars which are thought to originate through photoevaporation of the central protoplanetary disk by external UV radiation from the nearby OB stars. This Letter presents spatially resolved mid-infrared imaging and spectroscopy of the proplyd HST10 obtained with the Very Large Telescope/VISIR instrument. These observations allow us to detect polycyclic aromatic hydrocarbon (PAH) emission in the proplyd PDR and to study the general properties of PAHs in proplyds for the first time. We find that PAHs in HST10 are mostly neutral and at least 50 times less abundant than typical values found for the diffuse interstellar medium or the nearby Orion Bar. With such a low PAH abundance, photoelectric heating is significantly reduced. If this low abundance pertains also to the original disk material, gas heating rates could be too low to efficiently drive photoevaporation unless other processes can be identified. Alternatively, the model behind the formation of proplyds as evaporating disks may have to be revised.

FCC Tail Gas olefins conversion to gasoline via catalytic distillation with aromatics  

SciTech Connect

The goal of every refiner is to continually improve profitability by such means as increasing gasoline production, increasing gasoline octane pool and in cases where fuel balance becomes a problem, decreasing refinery fuel gas production. A new refinery process is currently being developed which accomplish these goals. Chemical Research and Licensing Company (CR and L) developed Catalytic Distillation technology in 1978 to produce MTBE. They have since used the Catalytic Distillation technique to produce cumene. CR and L has further developed this technology to convert olefin gases currently consumed as refinery fuel, to high octane gasoline components. The process, known as CATSTILL, alkylates olefin gases such as ethylene, propylene and butylene, present in FCC Tail Gas with light aromatics such as benzene, toluene and xylene, present in reformate, to produce additional quantities of high octane gasoline components. A portable CATSTILL demonstration plant has been constructed by Brown and Root U.S.A., under an agreement with CR and L, for placement in a refinery to further develop data necessary to design commercial plants. This paper presents current data relative to the CATSTILL development.

Hydrogenation of aromatics in synthetic crude distillates catalyzed by platinum supported in molecular sieves  

SciTech Connect

Catalytic hydrogenation of synthetic crude distillates from Canadian oil sands was carried out over platinum metal supported in pillared interlayered clay (PILC) and Y-zeolite. The molecular sieve supports were employed to modify the properties of dispersed platinum particles and improve their resistance to poisoning by sulfur. The objective was to reduce the distillate aromatic content to meet diesel emission control standards and cetane number requirements. Catalysts were prepared in a series of steps, and metal precursor was loaded using ion-exchange procedures. Characterization was done using X-ray diffraction, hydrogen chemisorption, and proton-induced X-ray emission elemental analysis. Catalytic hydrogenation reactions were carried out by processing distillate feedstocks both high (>100 ppm) and low (<10 ppm) in sulfur using a continuous-flow automated microreactor system. Experimental runs were performed to determine the reaction kinetics and Arrhenius parameters as a means of evaluating and comparing catalyst performance. Significant differences in catalyst activity were found. The Pt/Y-zeolite-alumina catalyst showed a much superior hydrogenation performance under conditions of high sulfur content. The extent of cracking and ring opening was also evaluated and was shown to be minimal under the operating conditions employed.

Removal of polycyclic aromatic hydrocarbons from surfactant solutions by selective sorption with organo-bentonite  

Science Journals Connector (OSTI)

Abstract Surfactant-enhanced soil washing is known to be an effective remediation approach for contaminated soils and groundwater. However, the recovery of surfactant solutions after soil washing is required for reducing the operation costs of the soil washing process. In this study, selective sorption with organo-bentonite was employed for the removal of polycyclic aromatic hydrocarbons (PAHs) from aqueous surfactant solution as a potential means of recovering surfactant solution after soil washing. The sorption of phenanthrene onto organo-bentonite from surfactant solution was well described by the pseudo-second-order kinetic model and the linear sorption isotherm model, respectively. \\{PAHs\\} can be effectively removed by organo-bentonite from surfactant solutions in a high proportion relative to the sorption loss of surfactant under all experimental conditions. The selectivity for PAH removal to surfactant sorption increased with increasing PAH hydrophobicity and surfactant hydrophilicity, but decreased with increasing surfactant concentration. However, increasing the organo-bentonite dose did not have obvious effect on the selectivity for surfactant recovery since it synchronously enhanced phenanthrene removal and surfactant sorption. The sorbent of organo-bentonite could be repeatedly used for recovering surfactant solution, which greatly reduced the sorption loss of surfactant and subsequently increased the selectivity for surfactant recovery considerably. The results suggest that selective sorption with organo-bentonite provides an alternative means of recovering surfactant solution after soil washing.

Determination of polynuclear aromatic hydrocarbons in seafood by liquid chromatography with fluorescence detection  

SciTech Connect

Modification of a previously published method for determination of polynuclear aromatic hydrocarbons (PAHs) produces very clean seafood extracts in less than half the time. After alkaline digestion of the seafood, PAHs were partitioned into 1,2,3-trichlorotrifluoroethane. The resulting extract was cleaned up by solid-phase extraction on alumina, silica, and C{sub 18} adsorbents and then analyzed by gradient reversed-phase liquid chromatography with programmable fluorescence detection. Average recoveries of 12 PAHs [acenaphthene, anthracene, fluoranthene, pyrene, benz(a)anthracene, chrysene, benzo(b)fluoranthene, benzo(k)-fluoranthene, benzo(k)-fluoranthene, benzo(a)pyrene, dibenz(a,h)anthracene, benzo(ghi)perylene, and indeno(1,2,3-cd)pyrene] from 5 different matrixes (mussels, oysters, clams, crabmeat, and salmon)spiked at low parts-per-billion levels ranged from 76 to 94%. Estimated limits of quantitation ranged from 0.01 to 0.6 ppb PAHs in extracts that were free of matrix interferences. Results of analyses of a mussels standard reference material obtained from the National Institute of Standards and Technology were in good agreement with the certified values. 16 refs., 3 figs., 4 tabs.

EXTINCTION AND POLYCYCLIC AROMATIC HYDROCARBON INTENSITY VARIATIONS ACROSS THE H II REGION IRAS 12063-6259  

SciTech Connect

The spatial variations in polycyclic aromatic hydrocarbon (PAH) band intensities are normally attributed to the physical conditions of the emitting PAHs, however in recent years it has been suggested that such variations are caused mainly by extinction. To resolve this question, we have obtained near-infrared (NIR), mid-infrared (MIR), and radio observations of the compact H II region IRAS 12063-6259. We use these data to construct multiple independent extinction maps and also to measure the main PAH features (6.2, 7.7, 8.6, and 11.2 {mu}m) in the MIR. Three extinction maps are derived: the first using the NIR hydrogen lines and case B recombination theory; the second combining the NIR data with radio data; and the third making use of the Spitzer/IRS MIR observations to measure the 9.8 {mu}m silicate absorption feature using the Spoon method and PAHFIT (as the depth of this feature can be related to overall extinction). The silicate absorption over the bright, southern component of IRAS 12063-6259 is almost absent while the other methods find significant extinction. While such breakdowns of the relationship between the NIR extinction and the 9.8 {mu}m absorption have been observed in molecular clouds, they have never been observed for H II regions. We then compare the PAH intensity variations in the Spitzer/IRS data after dereddening to those found in the original data. It was found that in most cases, the PAH band intensity variations persist even after dereddening, implying that extinction is not the main cause of the PAH band intensity variations.

Atmospheric distribution of polycyclic aromatic hydrocarbons and deposition to Galveston Bay, Texas, USA  

Science Journals Connector (OSTI)

Estimates of the atmospheric deposition to Galveston Bay of polycyclic aromatic hydrocarbons (PAHs) are made using precipitation and meteorological data that were collected continuously from 2 February 1995 to 6 August 1996 at Seabrook, TX, USA. Particulate and vapor phase \\{PAHs\\} in ambient air and particulate and dissolved phases in rain samples were collected and analyzed. More than 95% of atmospheric \\{PAHs\\} were in the vapor phase and about 73% of \\{PAHs\\} in the rain were in the dissolved phase. Phenanthrene and napthalene were the dominant compounds in air vapor and rain dissolved phases, respectively, while 5 and 6 ring PAH were predominant in the particulate phase of both air and rain samples. Total PAH concentrations ranged from 4 to 161ngm?3 in air samples and from 50 to 312ngl?1 in rain samples. Temporal variability in total PAH air concentrations were observed, with lower concentrations in the spring and fall (434ngm?3) compared to the summer and winter (37161ngm?3). \\{PAHs\\} in the air near Galveston Bay are derived from both combustion and petroleum vaporization. Gas exchange from the atmosphere to the surface water is estimated to be the major deposition process for \\{PAHs\\} (1211?gm? 2yr? 1), relative to wet deposition (130?gm?2yr? 1) and dry deposition (99?gm?2yr? 1). Annual deposition of \\{PAHs\\} directly to Galveston Bay from the atmosphere is estimated as 2 tyr?1.

Polycyclic aromatic hydrocarbons in fresh and smoked fish samples from three Nigerian cities  

SciTech Connect

Nigeria is a major producer of crude oil in sub-Saharan Africa. In-shore and off-shore wells are located in richly watered creeks in the southern part of the country. Although published data on environmental impact assessment of the petroleum industry in Nigeria are lacking, there is a growing concern about the possible contamination of estuarine and coastal waters and of marine species by polycyclic aromatic hydrocarbon (PAHs). PAHs are ubiquitous priority pollutants that occur naturally in crude oil, automobile exhaust emissions and smoke condensates from incomplete combustion of carbonaceous materials. PAHs with high molecular weight are less readily biodegraded by indigenous microorganisms in some regions, and given their marked hydrophobic characteristics, may persist in the aqueous environment, thus contaminating the food chain by bioaccumulating in aquatic species like fish and mussels. Major Nigerian oil wells are located in the vicinity of breeding and harvesting sites serving the fresh-water fishing industry. Large hauls of fresh fish are normally consumed cooked in soups or smoke cured in handcrafted traditional ovens using freshly cut red mangrove (Rhizophora racemosa) wood as fuel. Though smoke curing is economical and may ensure longer conservation of fish, it undoubtedly increases the burden of PAHs in finished products as a result of partial charring and from smoke condensates or mangroves that also contain PAHs in measurable quantities as reported by Asita et al. (1991). Apart from PAHs analyzed by Emerole (1980) in smoked food samples from Ibadan using simple analytical methods, those from industrial and other anthropogenic sources have rarely been analyzed in Nigeria. We tried therefore to update the data and address this discrepancy. 14 refs., 4 figs., 2 tabs.

Suppression of autophagy enhances the cytotoxicity of the DNA-damaging aromatic amine p-anilinoaniline  

SciTech Connect

p-Anilinoaniline (pAA) is an aromatic amine that is widely used in hair dying applications. It is also a metabolite of metanil yellow, an azo dye that is commonly used as a food coloring agent. Concentrations of pAA between 10 and 25 {mu}M were cytostatic to cultures of the normal human mammary epithelia cell line MCF10A. Concentrations {>=} 50 {mu}M were cytotoxic. Cytostatic concentrations induced transient G{sub 1} and S cell cycle phase arrests; whereas cytotoxic concentrations induced protracted arrests. Cytotoxic concentrations of pAA caused DNA damage, as monitored by the alkaline single-cell gel electrophoresis (Comet) assay, and morphological changes consistent with cells undergoing apoptosis and/or autophagy. Enzymatic and western blot analyses, and binding analyses of fluorescent labeled VAD-FMK, suggested that caspase family members were activated by pAA. Western blot analyses documented the conversion of LC3-I to LC3-II, a post-translational modification involved in the development of the autophagosome. Suppression of autophagosome formation, via knockdown of ATG7 with shRNA, prevented pAA-induced vacuolization, enhanced the activation of pro-caspase-3, and increased susceptibility of ATG7-deficient cells to the cytostatic and cytotoxic activities of markedly lower concentrations of pAA. Cells stably transfected with a nonsense shRNA behaved like parental MCF10A cells. Collectively, these data suggest that MCF10A cultures undergo autophagy as a pro-survival response to concentrations of pAA sufficient to induce DNA damage.

Nafion-H catalyzed efficient condensation of indoles with aromatic aldehydes in PEG-water solvent system: A green approach  

Science Journals Connector (OSTI)

Abstract Nafion-H has been used as an efficient and reusable catalyst for an improved and rapid synthesis of bis(indolyl)methanes from electrophilic substitution of indoles with aromatic aldehydes using PEG-400:water system as medium. This methodology offered remarkable improvements in the synthesis of bis(indolyl)methanes with regard to the yield of the products, operational simplicity and green aspects by avoiding the use of expensive, toxic catalysts and solvents. Also the catalyst could be recovered after the completion of reaction and reused several times without any significant loss in its catalytic potential.

Removal and degradation of aromatic compounds from a highly polluted site by coupling soil washing with photocatalysis  

Science Journals Connector (OSTI)

The possible application of two environmental remediation technologies soil washing and photocatalysis to remove and decompose various aromatic pollutants present in excavated soils of a contaminated industrial site has been investigated. Aqueous solutions containing the non-ionic surfactant Brij 35 were used to extract the contaminants from the soil samples. The photocatalytic treatment of the obtained washing wastes, performed in the presence of TiO2 suspensions irradiated with simulated sunlight, showed a slow abatement of the toxic compounds due to the relevant concentrations of organics in the waste. A neat improvement of the process performances, obtained by operating in the presence of added potassium peroxydisulfate, suggests a feasible treatment route.

The quantity of gonadal material was the most important correlate of PAH body burden. 3. Eggs, but not sperm, were enriched in chlorinated compounds (e.g. DDD, chlordane), while both eggs and sperm were enriched in total \\{PCBs\\} relative to somatic tissue. 4. Oysters may lose up to 50% of their total body burden of certain \\{PAHs\\} and pesticides in a single spawn.

INFRARED LUMINOSITIES AND AROMATIC FEATURES IN THE 24 {mu}m FLUX-LIMITED SAMPLE OF 5MUSES  

SciTech Connect

We study a 24 {mu}m selected sample of 330 galaxies observed with the infrared spectrograph for the 5 mJy Unbiased Spitzer Extragalactic Survey. We estimate accurate total infrared luminosities by combining mid-IR spectroscopy and mid-to-far infrared photometry, and by utilizing new empirical spectral templates from Spitzer data. The infrared luminosities of this sample range mostly from 10{sup 9} L{sub sun} to 10{sup 13.5} L{sub sun}, with 83% in the range 10{sup 10} L{sub sun} < L{sub IR} < 10{sup 12} L{sub sun}. The redshifts range from 0.008 to 4.27, with a median of 0.144. The equivalent widths of the 6.2 {mu}m aromatic feature have a bimodal distribution, probably related to selection effects. We use the 6.2 {mu}m polycyclic aromatic hydrocarbon equivalent width (PAH EW) to classify our objects as starburst (SB)-dominated (44%), SB-AGN composite (22%), and active galactic nucleus (AGN)-dominated (34%). The high EW objects (SB-dominated) tend to have steeper mid-IR to far-IR spectral slopes and lower L{sub IR} and redshifts. The low EW objects (AGN-dominated) tend to have less steep spectral slopes and higher L{sub IR} and redshifts. This dichotomy leads to a gross correlation between EW and slope, which does not hold within either group. AGN-dominated sources tend to have lower log(L{sub PAH7.7{sub {mu}m}}/L{sub PAH11.3{sub {mu}m}}) ratios than star-forming galaxies, possibly due to preferential destruction of the smaller aromatics by the AGN. The log(L{sub PAH7.7{sub {mu}m}}/L{sub PAH11.3{sub {mu}m}}) ratios for star-forming galaxies are lower in our sample than the ratios measured from the nuclear spectra of nearby normal galaxies, most probably indicating a difference in the ionization state or grain size distribution between the nuclear regions and the entire galaxy. Finally, we provide a calibration relating the monochromatic continuum or aromatic feature luminosity to L{sub IR} for different types of objects.

Abstract In our previous works, it was observed a clear relationship between the structure and the properties for different copoly(ether-imide)s, besides a good relation was found between SAXS characterization and permeability results. Here, a series of aliphatic aromatic copoly(ether-imide)s, based on an aromatic diamine (ODA), a diamine terminated poly(ethylene oxide) (PEO2000) of a molecular weight of 2000g/mol and different aromatic dianhydrides (BPDA, BKDA (or BTDA) and PMDA) has been synthesized and characterized. The permeability for O2, N2, CO2 and CH4, increased with the rigidity of the monomers (BKDACO2/N2 separation. This work gives indications on how to design advanced materials for this separation with the increasing possibilities of controlled structure and properties.

Biomarker sensitivity for polynuclear aromatic hydrocarbon contamination in two marine fish species collected in Galveston Bay, Texas  

SciTech Connect

The Galveston Bay estuary exhibited a contamination gradient for polynuclear aromatic hydrocarbons (PAHs) and halogenated aromatic hydrocarbons, and the comparative sensitivity of various biomarkers in fish from different bay locations were determined. Two fish species, hardhead catfish (Arius felis) and Atlantic croaker (Micropogon undulatus), were collected from four stations where sediment total PAHs ranged from 68 > 1,000 ng/g. The induction of cytochrome P4501A-(CYP1A)-dependent hepatic ethoxyresorufin-O-deethylase (EROD) activity, CYPIA mRNA levels, or CYPIA immunoreactive protein in hardhead catfish was highly variable in the field-collected fish and in fish dosed with up to 15 mg/kg benzo[a]pyrene (BaP). In contrast, significant differences were seen in biliary concentrations of naphthalene, phenanthrene, and BaP metabolites in hardhead catfish from polluted versus less polluted areas. In croakers taken from the same four Galveston Bay locations, EROD and glutathione S-transferase activities, immunoreactive CYP1A protein, biliary PAH metabolites, and PAH-DNA adducts were higher at the contaminated stations compared with less polluted locations. These studies suggest that the croaker is a good species for monitoring contaminants that induce CYP1A-mediated responses. Biliary PAH metabolites and PAH-DNA adducts were also sensitive indicators of exposure to PAH contamination in both species of fish.

UV-vis spectra of singlet state cationic polycyclic aromatic hydrocarbons: Time-dependent density functional theory study  

SciTech Connect

A theoretical study of singlet state cations of polycyclic aromatic hydrocarbons is performed. Appropriate symmetry suitable for further calculations is chosen for each of the systems studied. The excitation states of such species are obtained by the time dependent density functional theory (TD-DFT) method. The computations are performed using both Pople and electronic response properties basis sets. The results obtained with the use of different basis sets are compared. The electronic transitions are described and the relationships for the lowest-lying transitions states of different species are found. The properties of in-plane and out-of-plane transitions are also delineated. The TD-DFT results are compared with the experimental data available.

Vibrational mode analysis of void induced coronene as a possible carrier of the astronomical aromatic infrared bands  

E-Print Network (OSTI)

Void induced di-cation coronene C23H12++ is a possible carrier of the astronomically observed polycyclic aromatic hydrocarbon (PAH). Based on density functional theory, multiple spin state analysis was done for neutral void coronene C23H12. Singlet spin state was most stable (lowest total energy). By the Jahn-Teller effect, there occurs serious molecular deformation. Point group D6h of pure coronene transformed to C2 symmetry having carbon two pentagons. Advanced singlet stable molecules were di-cation C23H12++ and di-anion C23H12- -. Molecular configuration was almost similar with neutral C23H12. However, electric dipole moment of these two charged molecules show reversed direction with 1.19 and 2.63 Debey. Calculated infrared spectrum of C23H12++ show a very likeness to observed one of two astronomical sources of HD44179 and NGC7027. Harmonic vibrational mode analysis was done for C23H12++. At 3.2 micrometer, C-H stretching at pentagons was featured. From 6.4 to 8.7 micrometer, C-C stretching mode was obser...

Source Contribution Analysis of Surface Particulate Polycyclic Aromatic Hydrocarbon Concentrations in Northeastern Asia by Source-receptor Relationships  

SciTech Connect

We analyzed the sourceereceptor relationships for particulate polycyclic aromatic hydrocarbon (PAH) concentrations in northeastern Asia using an aerosol chemical transport model. The model successfully simulated the observed concentrations. In Beijing (China) benzo[a]pyren (BaP) concentrations are due to emissions from its own domain. In Noto, Oki and Tsushima (Japan), transboundary transport from northern China (>40N, 40-60%) and central China (30-40N, 10-40%) largely influences BaP concentrations from winter to spring, whereas the relative contribution from central China is dominant (90%) in Hedo. In the summer, the contribution from Japanese domestic sources increases (40-80%) at the 4 sites. Contributions from Japan and Russia are additional source of BaP over the northwestern Pacific Ocean in summer. The contribution rates for the concentrations from each domain are different among PAH species depending on their particulate phase oxidation rates. Reaction with O3 on particulate surfaces may be an important component of the PAH oxidation processes.

Distribution of polycyclic aromatic hydrocarbons in fly ash during coal and residual char combustion in a pressurized fluidized bed  

SciTech Connect

To investigate the distribution of polycyclic aromatic hydrocarbons (PAHs) in fly ash, the combustion of coal and residual char was performed in a pressurized spouted fluidized bed. After Soxhlet extraction and Kuderna-Danish (K-D) concentration, the contents of 16 PAHs recommended by the United States Environmental Protection Agency (U.S. EPA) in coal, residual char, and fly ash were analyzed by a high-performance liquid chromatography (HPLC) coupled with fluorescence and diode array detection. The experimental results show that the combustion efficiency is lower and the carbon content in fly ash is higher during coal pressurized combustion, compared to the residual char pressurized combustion at the pressure of 0.3 MPa. Under the same pressure, the PAH amounts in fly ash produced from residual char combustion are lower than that in fly ash produced from coal combustion. The total PAHs in fly ash produced from coal and residual char combustion are dominated by three- and four-ring PAHs. The amounts of PAHs in fly ash produced from residual char combustion increase and then decrease with the increase of pressure in a fluidized bed. 21 refs., 1 fig., 4 tabs.

POLYCYCLIC AROMATIC HYDROCARBONS IN GALAXIES AT z approx 0.1: THE EFFECT OF STAR FORMATION AND ACTIVE GALACTIC NUCLEI  

SciTech Connect

We present the analysis of the polycyclic aromatic hydrocarbon (PAH) spectra of a sample of 92 typical star-forming galaxies at 0.03 < z < 0.2 observed with the Spitzer intensified Reticon spectrograph (IRS). We compare the relative strengths of PAH emission features with Sloan Digital Sky Survey optical diagnostics to probe the relationship between PAH grain properties and star formation and active galactic nuclei (AGNs) activity. Short-to-long wavelength PAH ratios, and in particular the 7.7 mum-to-11.3 mum feature ratio, are strongly correlated with the star formation diagnostics D{sub n} (4000) and Halpha equivalent width, increasing with younger stellar populations. This ratio also shows a significant difference between active and non-active galaxies, with the active galaxies exhibiting weaker 7.7 mum emission. A hard radiation field as measured by [O{sub III}]/Hbeta and [Ne{sub III}]{sub 15.6m}u{sub m}/[Ne{sub II}]{sub 12.8m}u{sub m} effects PAH ratios differently depending on whether this field results from starburst activity or an AGN. Our results are consistent with a picture in which larger PAH molecules grow more efficiently in richer media and in which smaller PAH molecules are preferentially destroyed by the AGN.

Synergistic effect of mixing dimethyl ether with methane, ethane, propane, and ethylene fuels on polycyclic aromatic hydrocarbon and soot formation  

SciTech Connect

Characteristics of polycyclic aromatic hydrocarbon (PAH) and soot formation in counterflow diffusion flames of methane, ethane, propane, and ethylene fuels mixed with dimethyl ether (DME) have been investigated. Planar laser-induced incandescence and fluorescence techniques were employed to measure relative soot volume fractions and PAH concentrations, respectively. Results showed that even though DME is known to be a clean fuel in terms of soot formation, DME mixture with ethylene fuel increases PAH and soot formation significantly as compared to the pure ethylene case, while the mixture of DME with methane, ethane, and propane decreases PAH and soot formation. Numerical calculations adopting a detailed kinetics showed that DME can be decomposed to produce a relatively large number of methyl radicals in the low-temperature region where PAH forms and grows; thus the mixture of DME with ethylene increases CH{sub 3} radicals significantly in the PAH formation region. Considering that the increase in the concentration of O radicals is minimal in the PAH formation region with DME mixture, the enhancement of PAH and soot formation in the mixture flames of DME and ethylene can be explained based on the role of methyl radicals in PAH and soot formation. Methyl radicals can increase the concentration of propargyls, which could enhance incipient benzene ring formation through the propargyl recombination reaction and subsequent PAH growth. Thus, the result substantiates the importance of methyl radicals in PAH and soot formation, especially in the PAH formation region of diffusion flames. (author)

Chemical and morphological characterization of soot and soot precursors generated in an inverse diffusion flame with aromatic and aliphatic fuels  

SciTech Connect

Knowledge of the chemical and physical structure of young soot and its precursors is very useful in understanding the paths leading to soot particle inception. This paper presents chemical and morphological characterization of the products generated in ethylene and benzene inverse diffusion flames (IDF) using different analytical techniques. The trend in the data indicates that the soot precursor material and soot particles generated in the benzene IDF have a higher degree of complexity than the samples obtained in the ethylene IDF, which is reflected by an increase in the aromaticity of the chloroform extracts observed by {sup 1}H NMR and FT-IR, and shape and size of soot particles obtained by TEM and HR-TEM. It is important to highlight that the soot precursor material obtained at the lower positions in the ethylene IDF has a significant contribution of aliphatic groups, which play an important role in the particle inception and mass growth processes during the early stages of soot formation. However, these groups progressively disappear in the samples taken at higher positions in the flame, due to thermal decomposition processes. (author)

Probabilistic ecological risk assessment and source apportionment of polycyclic aromatic hydrocarbons in surface sediments from Yellow Sea  

SciTech Connect

Based on the concentrations of polycyclic aromatic hydrocarbons (PAHs) in 12 surface sediment samples from Yellow Sea, the relative risk of 9 PAHs was investigated using joint risk probability distribution curves and overlapping area, which were generated based on the distributions of exposure and acute toxicity data (LC50), and the sources of PAHs were apportioned using principal component analysis. It was found that joint probability curve and overlapping area indicated the acceptable ecological risk of individual PAHs, only a small fraction of the benthic organisms was affected. Among the nine PAHs studied, the overall risk of pyrene was the highest, with that of naphthalene the lowest. For lower exposure levels at which the percentage of species affected was less than 10%, the risk associated with phenanthrene and fluorene were clearly higher than that of the other seven PAHs. It was indicated that PAHs in surface sediments mainly originated from vehicular emissions, coal combustion sources, coke oven emission and wood combustion, petroleum origin made little influence on sources of PAHs by PCA.

Physicochemical characterization of coke-plant soil for the assessment of polycyclic aromatic hydrocarbon availability and the feasibility of phytoremediation  

SciTech Connect

Coke oven site soil was characterized to assess the particle association and availability of polycyclic aromatic hydrocarbons (PAHs). We identified various carbonaceous materials including coal, coke, pitch, and tar decanter sludge. Most of the PAHs were associated with the polymeric matrix of tar sludge or hard pitch as discrete particles, coatings on soil mineral particles, or complex aggregates. The PAH availability from these particles was very low due to hindered diffusive release from solid tar or pitch with apparent diffusivities of 6 x 10{sup -15} for phenanthrene, 3 x 10{sup -15} for pyrene, and 1 x 10{sup -15} cm{sup 2}/s for benzo(a)pyrene. Significant concentrations of PAHs were observed in the interior of solid tar aggregates with up to 40,000 mg/kg total PAHs. The release of PAHs from the interior of such particles requires diffusion over a substantial distance, and semipermeable membrane device tests confirmed a very limited availability of PAHs. These findings explain the results from three years of phytoremediation of the site soil, for which no significant changes in the total PAH concentrations were observed in the test plot samples. The observed low bioavailability of PAHs probably inhibited PAH phytoremediation, as diffusion-limited mass transfer would limit the release of PAHs to the aqueous phase.

Dispersion modeling of polycyclic aromatic hydrocarbons from combustion of biomass and fossil fuels and production of coke in Tianjin, China  

SciTech Connect

A USEPA procedure, ISCLT3 (Industrial Source Complex Long-Term), was applied to model the spatial distribution of polycyclic aromatic hydrocarbons (PAHs) emitted from various sources including coal, petroleum, natural gas, and biomass into the atmosphere of Tianjin, China. Benzo(a)pyrene equivalent concentrations (BaPeq) were calculated for risk assessment. Model results were provisionally validated for concentrations and profiles based on the observed data at two monitoring stations. The dominant emission sources in the area were domestic coal combustion, coke production, and biomass burning. Mainly because of the difference in the emission heights, the contributions of various sources to the average concentrations at receptors differ from proportions emitted. The shares of domestic coal increased from {approximately} 43% at the sources to 56% at the receptors, while the contributions of coking industry decreased from {approximately} 23% at the sources to 7% at the receptors. The spatial distributions of gaseous and particulate PAHs were similar, with higher concentrations occurring within urban districts because of domestic coal combustion. With relatively smaller contributions, the other minor sources had limited influences on the overall spatial distribution. The calculated average BaPeq value in air was 2.54 {+-} 2.87 ng/m{sup 3} on an annual basis. Although only 2.3% of the area in Tianjin exceeded the national standard of 10 ng/m{sup 3}, 41% of the entire population lives within this area. 37 refs., 9 figs.

Black-Right-Pointing-Pointer The result showed high reduction of all tested parameters after treatment. Black-Right-Pointing-Pointer Plants improve degradation and Phragmites australis is tolerant to xenobiotics. Black-Right-Pointing-Pointer The amount of sludge could be reduced by 50-70%. - Abstract: Since the mid-1970s, Sweden has been depositing 1 million ton d.w sludge/year, produced at waste water treatment plants. Due to recent legislation this practice is no longer a viable method of waste management. It is necessary to improve existing and develop new sludge management techniques and one promising alternative is the dewatering and treatment of sludge in constructed wetlands. The aim of this study was to follow reduction of organic carbon, BOD and nutrients in an industrial sludge containing nitro-aromatic compounds passing through constructed small-scale wetlands, and to investigate any toxic effect such as growth inhibition of the common reed Phragmites australis. The result showed high reduction of all tested parameters in all the outgoing water samples, which shows that constructed wetlands are suitable for carbon and nutrient removal. The results also showed that P. australis is tolerant to xenobiotics and did not appear to be affected by the toxic compounds in the sludge. The sludge residual on the top of the beds contained low levels of organic carbon and is considered non-organic and could therefore be landfilled. Using this type of secondary treatment method, the amount of sludge could be reduced by 50-70%, mainly by dewatering and biodegradation of organic compounds.

Solubilities of nitrogen in selected naphthenic and aromatic hydrocarbons at temperatures from 344 to 433 K and pressures to 22.8 MPa  

SciTech Connect

The solubilities of nitrogen in selected naphthenic (cyclohexane and trans-Decalin) and aromatic (benzene, naphthalene, 1-methylnaphthalene, phenanthrene, pyrene) solvents were measured using a static equilibrium cell over the temperature range from 344.3 to 433.2 K at pressures to 22.8 MPa. The uncertainty in these measurements is estimated to be less than 0.001 in mole fraction. The Peng-Robinson equation of state was shown to represent the experimental data with root-mean-square deviations of about 0.002 when a single interaction parameter (C{sub ij}) is used for each binary system.

Effect of B20 and Low Aromatic Diesel on Transit Bus NOx Emissions Over Driving Cycles with a Range of Kinetic Intensity  

SciTech Connect

Oxides of nitrogen (NOx) emissions for transit buses for up to five different fuels and three standard transit duty cycles were compared to establish whether there is a real-world biodiesel NOx increase for transit bus duty cycles and engine calibrations. Six buses representing the majority of the current national transit fleet and including hybrid and selective catalyst reduction systems were tested on a heavy-duty chassis dynamometer with certification diesel, certification B20 blend, low aromatic (California Air Resources Board) diesel, low aromatic B20 blend, and B100 fuels over the Manhattan, Orange County and UDDS test cycles. Engine emissions certification level had the dominant effect on NOx; kinetic intensity was the secondary driving factor. The biodiesel effect on NOx emissions was not statistically significant for most buses and duty cycles for blends with certification diesel, except for a 2008 model year bus. CARB fuel had many more instances of a statistically significant effect of reducing NOx. SCR systems proved effective at reducing NOx to near the detection limit on all duty cycles and fuels, including B100. While offering a fuel economy benefit, a hybrid system significantly increased NOx emissions over a same year bus with a conventional drivetrain and the same engine.

Selective detection of primary aromatic amines in complex mixtures by liquid chromatography with electrochemical detection using a short reversed-phase column  

SciTech Connect

Selective detection of primary aromatic amines (PAAs) in the presence of phenols by liquid chromatography with electrochemical detection was investigated. PAAs were resolved from other aromatic compounds, using three mobile phases, at various electrode potentials and flow rates. The phases used a combination of pH and organic modifiers (tetrahydrofuran, acetonitrile, or n-propanol) to optimize the degree of separation. As the pH of the mobile phase was increased, the signals for two- and three-ring PAAs decreased and became independent of pH at values between 4 and 8, while the signals from aniline and phenols increased. Selective detection of PAAs is feasible at pH 2.2 at potentials of 0.7 to 0.85 V vs Ag/AgCl. The best result was obtained with a 35 vol % tetrahydrofuran/water mobile phase, which yielded the highest signal for aniline and the lowest signal for phenol at pH 2.2 with satisfactory retention times. Electrochemical detectors are about one thousand times more sensitive to PAAs and phenols than ultraviolet detectors. The results obtained will permit design and construction of a portable PAA monitor with an appropriate sample concentrator, pump, and injection system. 20 refs., 11 figs., 2 tabs.

Effect of Soederberg smelting technology, anode paste composition, and work shift on the relationship between benzo(a)pyrene and individual polycyclic aromatic hydrocarbons  

SciTech Connect

This follow-up of the Farant and Gariepy study investigates the relationship between benzo(a)pyrene (B(a)P) and other polycyclic aromatic hydrocarbons (PAHs) found in coal tar pitch volatiles in two types of Soederberg aluminum smelters horizontal and vertical stud. The study confirms the strong relationships between B(a)P and total PAHs, and that B(a)P was a good indicator for other PAHs in this industry. The PAH profiles were consistent within each smelter, but the smelter technology used and the changes in the raw material formulation resulted in significantly different profiles. B(a)P toxic equivalency factors for emitted PAH mixtures were greater in the horizontal stud smelter than in the vertical stud smelter. Overall, this study illustrates the potential usefulness of B(a)P relative abundance ratios to simplify exposure assessment in the workplace and reduce associated costs.

Water Ice, Silicate, and Polycyclic Aromatic Hydrocarbon Emission Features in the Infrared Space Observatory Spectrum of the Carbon-Rich Planetary Nebula CPD -56 degree 8032  

E-Print Network (OSTI)

Combined ISO SWS and LWS spectroscopy is presented of the late WC-type planetary nebula nucleus CPD-56 8032 and its carbon-rich nebula. The extremely broad coverage (2.4-197 microns) enables us to recognize the clear and simultaneous presence of emission features from both oxygen- and carbon- rich circumstellar materials. Removing a smooth continuum highlights bright emission bands characteristic of polycyclic aromatic hydrocarbons (hereafter PAHs) in the 3-14 micron region, bands from crystalline silicates longwards of 18 microns, and the 43- and 62-micron bands of crystalline water ice. We discuss the probable evolutionary state and history of this unusual object in terms of (a) a recent transition from an O-rich to a C-rich outflow following a helium shell flash; or (b) a carbon-rich nebular outflow encountering an O-rich comet cloud.

Process development studies in coal gasification. Volume II. Reaction of aromatic compounds with steam. Final report, August 1, 1979-November 30, 1983  

SciTech Connect

The objective of this research has been to explore and define the potential of steam reforming to produce light gases from coal-derived liquids. This was achieved through a study of the reaction of a model aromatic compound and of a coal-derived liquid with steam over an alumina supported nickel catalyst. The reaction of steam with benzene and SRC-II liquids over an alumina supported nickel catalyst has been investigated in a plug flow reactor. The primary process variables investigated were reactor pressure and temperature, contact time, and steam/carbon ratio. A proposed reaction network was also developed to explain the data obtained in this study. The effect of process variables on the conversion and product distribution when steam reforming the SRC-II coal-derived liquid was similar to that observed for benzene-steam reforming. The results indicated that a high yield of methane is favored at high pressures, low temperatures, and low steam-to-carbon ratios; and that a high yield of hydrogen is favored at low pressures and high steam-to-carbon ratios. The empirical rate equation for the benzene steam reforming reaction at 973 K, 300 psig, and a steam/carbon ratio of approximately 3 was r/sub C/sub 6/H/sub 6// = 1.92 x 10/sup -3/ P/sub C/sub 6/H/sub 6//. The activation energy was 88 KJ/mol, or 21 kcal/mol in the temperature range 748-973 K. A correlation was developed to predict product yields and hydrocarbon conversion over the range of process variables investigated. A second correlation was developed to predict the yields and conversion beyond the range of variables investigated. A reaction network for aromatic steam reforming was proposed. 87 refs., 47 figs., 3 tabs.

Aromatic hydrocarbon receptor inhibits lysophosphatidic acid-induced vascular endothelial growth factor-A expression in PC-3 prostate cancer cells  

SciTech Connect

Highlights: LPA-induced VEGF-A expression was regulated by HIF-1? and ARNT. PI3K mediated LPA-induced VEGF-A expression. AHR signaling inhibited LPA-induced VEGF-A expression in PC-3 cells. -- Abstract: Lysophosphatidic acid (LPA) is a lipid growth factor with multiple biological functions and has been shown to stimulate cancer cell secretion of vascular endothelial growth factor-A (VEGF-A) and trigger angiogenesis. Hypoxia-inducible factor-1 (HIF-1), a heterodimer consisting of HIF-1? and HIF-1? (also known as aromatic hydrocarbon receptor nuclear translocator (ARNT)) subunits, is an important regulator of angiogenesis in prostate cancer (PC) through the enhancement of VEGF-A expression. In this study, we first confirmed the ability of LPA to induce VEGF-A expression in PC-3 cells and then validated that LPA-induced VEGF-A expression was regulated by HIF-1? and ARNT through phosphatidylinositol 3-kinase activation. Aromatic hydrocarbon receptor (AHR), a receptor for dioxin-like compounds, functions as a transcription factor through dimerization with ARNT and was found to inhibit prostate carcinogenesis and vanadate-induced VEGF-A production. Since ARNT is a common dimerization partner of AHR and HIF-1?, we hypothesized that AHR might suppress LPA-induced VEGF-A expression in PC-3 cells by competing with HIF-1? for ARNT. Here we demonstrated that overexpression and ligand activation of AHR inhibited HIF-1-mediated VEGF-A induction by LPA treatment of PC-3 cells. In conclusion, our results suggested that AHR activation may inhibit LPA-induced VEGF-A expression in PC-3 cells by attenuating HIF-1? signaling, and subsequently, suppressing angiogenesis and metastasis of PC. These results suggested that AHR presents a potential therapeutic target for the prevention of PC metastasis.

The bonding, charge distribution, spin ordering, optical, and elastic properties of four MAX phases Cr{sub 2}AX (A?=?Al or Ge, X?=?C or N): From density functional theory study  

SciTech Connect

In this work, we assess a full spectrum of properties (chemical bonding, charge distribution, spin ordering, optical, and elastic properties) of Cr{sub 2}AC (A?=?Al, Ge) and their hypothetical nitride counterparts Cr{sub 2}AN (A?=?Al, Ge) based on density functional theory calculations. The calculated total energy values indicate that a variety of spin ordering of these four compounds depending on interlayer-interactions between M-A and M-X within the sublattice, which is supported by bonding analysis. MAX phase materials are discovered to possess exotic magnetic properties which indicates that these materials could serve as promising candidates for novel layered magnetic materials for various electronic and spintronic applications. Further analysis of optical properties for two polarization vectors of Cr{sub 2}AX shows that the reflectivity is high in the visible-ultraviolet region up to ?15?eV suggesting Cr{sub 2}AX as a promising candidate for use as a coating material. The elastic coefficients (C{sub ij}) and bulk mechanical properties [bulk modulus (K), shear modulus (G), Young's modulus (E), Poisson's ratio (?), and Pugh ratio (G/K)] of these four Cr{sub 2}AX compounds are also calculated and analyzed, which pave the way to predict or design new MAX phases that are less brittle or tougher by having a lower G/K value or higher ?.

Synthesis of g-C3N4/Fe3O4 nanocomposites and application as a new sorbent for solid phase extraction of polycyclic aromatic hydrocarbons in water samples  

Science Journals Connector (OSTI)

Abstract An easy preparation of g-C3N4/Fe3O4 nanocomposites by chemical co-precipitation has been demonstrated. The as-prepared materials were characterized by X-ray diffraction, transmission electron microscopy, Fourier transform infrared spectroscopy and thermogravimetric analysis. The high affinity of g-C3N4 toward polycyclic aromatic hydrocarbons and the magnetic behavior of Fe3O4 were combined to provide an efficient and simple magnetic solid phase extraction (MSPE). The adsorption and desorption of polycyclic aromatic hydrocarbons on g-C3N4/Fe3O4 were examined. Different factors affecting the magnetic solid phase extraction of polycyclic aromatic hydrocarbons were assessed in terms of adsorption, desorption, and recovery. Under the optimized conditions, the proposed method showed good limits of detection (LOD, S/N=3) in the range of 0.050.1ngmL?1 and precision in the range of 1.85.3% (RSDs, n=3). This method was also successfully applied to the analysis of real water samples; good spiked recoveries over the range of 80.099.8% were obtained.

Femtosecond-picosecond laser photolysis studies on the dynamics of excited charge-transfer complexes: Aromatic hydrocarbon-acid anhydride, -tetracyanoethylene, and -tetracyanoquinodimethane systems in acetonitrile solutions  

SciTech Connect

Formation processes of contact ion pairs (CIP) from the excited Franck-Condon (FC) state of charge-transfer (CT) complexes of aromatic hydrocarbons with acid anhydride as well as cyano compound acceptors in acetonitrile solution and charge recombination (CR) rates (k{sub CR}{sup CIP}) of produced CIP states have been investigated by femtosecond and picosecond laser phototlysis and time-resolved absorption spectral measurements covering a wide range of free energy gap-{Delta}G{degree}{sub ip} between the ion pair and the ground state. It has been confirmed that the CIP formation becomes faster and k{sub CR}{sup CIP} of the produced CIP increases with increase of the strengths of the electron donor (D) and acceptor (A) in the complex, i.e., with decrease of the {minus}{Delta}G{degree}{sub ip} value. This peculiar energy gap dependence of k{sub CR}{sup CIP}, quite different from the bell-shaped one observed in the case of the solvent-separated ion pairs (SSIP) or loose ion pairs (LIP) formed by encounter between fluorescer and quencher in the fluoresence quenching reaction, has been interpreted by assuming the change of electronic and geometrical structures of CIP depending on the strengths of D and A.

Synergistic selective extraction of actinides(III) over lanthanides from nitric acid using new aromatic diorganyldithiophosphinic acids and neutral organophosphorus compounds  

SciTech Connect

New aromatic dithiophosphinic acids (R{sub 2}PSSH) with R = C{sub 6}H{sub 5{sup {minus}}}, ClC{sub 6}H{sub 4{sup {minus}}}, FC{sub 6}H{sub 4{sup {minus}}} and CH{sub 3}C{sub 6}H{sub 4{sup {minus}}} were synthesized, characterized and tested as potential separating agents for trivalent actinides over lanthanides. The extraction of Am(III), Eu(III) and other lanthanides was carried out from nitric acid medium with mixtures of R{sub 2}PSSHs and neutral organophosphorus compounds. There was no detectable extraction when R{sub 2}PSSHs were used alone as extractants for either Am(III) or Eu(III) (D{sub Am,Eu} < 10{sup {minus}3}) under the experimental conditions used in this study. High separation factors (D{sub Am}/D{sub Eu} > 20) with D{sub Am} > 1 were achieved in the nitric acid range 0.1--1 mol/L by means of a synergistic mixture of bis(chlorophenyl)dithiophosphinic acid + tributylphosphate (TBP), trioctylphosphine oxide (TOPO) or tributylphosphine oxide (TBPO). The high radiation resistance (up to 10{sup 6} Gy absorbed {gamma}-doses) of the extractants was also demonstrated.

MID-INFRARED POLYCYCLIC AROMATIC HYDROCARBON AND H{sub 2} EMISSION AS A PROBE OF PHYSICAL CONDITIONS IN EXTREME PHOTODISSOCIATION REGIONS  

SciTech Connect

Mid-infrared (mid-IR) observations of polycyclic aromatic hydrocarbons (PAHs) and molecular hydrogen emission are a potentially powerful tool to derive physical properties of dense environments irradiated by intense UV fields. We present new, spatially resolved, Spitzer mid-IR spectroscopy of the high UV field and dense photodissociation region (PDR) around Monoceros R2, the closest ultracompact H II region, revealing the spatial structure of ionized gas, PAHs, and H{sub 2} emissions. Using a PDR model and PAH emission feature fitting algorithm, we build a comprehensive picture of the physical conditions prevailing in the region. We show that the combination of the measurement of PAH ionization fraction and of the ratio between the H{sub 2} 0-0 S(3) and S(2) line intensities, respectively, at 9.7 and 12.3 mum, allows us to derive the fundamental parameters driving the PDR: temperature, density, and UV radiation field when they fall in the ranges T = 250-1500 K, n {sub H} = 10{sup 4}-10{sup 6} cm{sup -3}, and G {sub 0} = 10{sup 3}-10{sup 5}, respectively. These mid-IR spectral tracers thus provide a tool to probe the similar but unresolved UV-illuminated surface of protoplanetary disks or the nuclei of starburst galaxies.

Science Journals Connector (OSTI)

Abstract Surface tension (?, mN/m) of benzene, toluene and ethylbenzene (EB) aromatic hydrocarbons (AHCs, low density liquids, LDL) and interfacial tension (IFT, mN/m) both with water and aqueous 0.1, 0.5, 1.0molkg?1 KF, KCl, KBr, KI (high density liquids, HDL) separately at 303.15K are reported. Contributions of CH3 and CH2CH3 of toluene and EB to hydrophobic interactions are calculated from ?toluene?benzene and ?EB?benzene, respectively. \\{IFTs\\} of water+AHCs liquidliquid interfaces (LLI) are as toluene (34.71)>EB (32.35)>benzene (32.32mNm?1), with a ~32.32mNm?1 decrease from 71.40mNm?1 of water. \\{AHCs\\} with hyperconjugation (HC) and positive inductive effects (+ve IE) with toluene and EB LLI have reduced IFT by 39.08, 2.39, ?1.56mNm?1, respectively. The effects of ?-conjugation, H, CH3 and CH2CH3 on surface tension are calculated as ?-conjugation=?(IFTairliquid?IFTAPHSbenzene), CH3=?(IFTAPHStoluene?IFTAPHSbenzene). The effects of halide salts on hypercongugation H(CH3)/3, CH2CH3 are obtained from ?(IFTAPHSEB ?IFTAPHSbenzene).

Development of a new sorptive extraction method based on simultaneous direct and headspace sampling modes for the screening of polycyclic aromatic hydrocarbons in water samples  

Science Journals Connector (OSTI)

Abstract A new straightforward and inexpensive sample screening method for both EPA and EU priority polycyclic aromatic hydrocarbons (PAHs) in water has been developed. The method is based on combined direct immersion and headspace (DIHS) sorptive extraction, using low-cost disposable material, coupled to ultraperformance liquid chromatography with fluorescence and UV detection (UPLC-FD-UV). Extraction parameters, such as the sampling mode, extraction time and ionic strength were investigated in detail and optimized. Under optimized conditions, water samples (16mL) were concentrated in silicone disks by headspace (HS) and direct immersion (DI) modes simultaneously, at room temperature for 9h for the majority of the 24 studied compounds. Ultrasound-assisted desorption of extracted analytes in acetonitrile was carried out also at room temperature. The optimized chromatographic method provided a good linearity (R?0.9991) and a broad linear range for all studied PAHs. The proposed analytical procedure exhibited a good precision level with relative standard deviations below 15% for all analytes. Quantification limits between 0.7 and 2.3gL?1 and 0.16 and 3.90ngL?1 were obtained for compounds analyzed by UV (acenaphtylene, cyclopenta[c,d]pyrene and benzo[j]fluoranthene) and fluorescence, respectively. Finally, the proposed method was applied to the determination of \\{PAHs\\} in different real tap, river and wastewater samples.

Gas chromatographic determination of polycyclic aromatic hydrocarbons in water and smoked rice samples after solid-phase microextraction using multiwalled carbon nanotube loaded hollow fiber  

Science Journals Connector (OSTI)

Abstract A novel solid-phase microextraction fiber was prepared based on multiwalled carbon nanotubes (MWCNTs) loaded on hollow fiber membrane pores. Stainless steel wire was used as unbreakable support. The major advantages of the proposed fiber are its (a) high reproducibility due to the uniform structure of the hollow fiber membranes, (b) high extraction capacity related to the porous structure of the hollow fiber and outstanding adsorptive characteristics of MWCNTs. The proposed fiber was applied for the microextraction of five representative polycyclic aromatic hydrocarbons (PAHs) from aqueous media (river and hubblebubble water) and smoked rice samples followed by gas chromatographic determination. Analytical merits of the method, including high correlation coefficients [(0.99630.9992) and (0.99820.9999)] and low detection limits [(9.013.0ngL?1) and (40.0150.0ngkg?1)] for water and rice samples, respectively, made the proposed method suitable for the ultra-trace determination of PAHs.

Simultaneous liquidliquid and vapourliquid equilibria predictions of selected oxygenated aromatic molecules in mixtures with alkanes, alcohols, water, using the polar GC-PC-SAFT  

Science Journals Connector (OSTI)

Abstract Phase equilibria of oxygen-bearing aromatic compounds, hydrocarbons and water mixtures are of essential interest in many processes using feeds originating from biomass. The strong non-ideal thermodynamic behavior of these systems sometimes results in immiscibility with both water and alkanes. To address this problem, the GC-PPC-SAFT equation of state [Tamouza et al., 2004; Nguyen-Huynh et al., 2008a] is extended to some selected components: phenol, alkyl-phenols, alkyl-benzoates, benzaldehyde and anisole. However, as in these multifunctional compounds, the proximity of polar functional groups may result in a lack of transferability of the parameters from the monofunctional homologous species, some parameters have been adapted in view of physical arguments. Next, liquidvapour and liquidliquid equilibria of mixtures with n-alkanes were evaluated, using a predictive method for the binary interaction parameters (kij) [Nguyen-Huynh et al., 2008b]. Finally, mixtures with other associating compounds, as alcohols and water have also been considered. In all cases, both correlations and predictions are qualitatively and quantitatively satisfactory. The relative deviations obtained on bubble pressure of vaporliquid equilibria are 48%, that is comparable to those obtained on previously investigated systems.

Constraining uncertainties about the sources and magnitude of ambient air exposures to polycyclic aromatic hydrocarbons (PAHs): The state of Minnesota as a case study  

SciTech Connect

Emissions data are often lacking or uncertain for many airborne contaminants. Chemicals, such as polycyclic aromatic hydrocarbons (PAHs), emitted from combustion sources, fall into this category. Currently available ambient-air emission inventories of PAHs either fail to account for population-based activities (such as residential wood combustion and motor vehicle activity) and/or report ''total PAH'' or particulate organic matter emissions instead of individual compounds. We measure the degree of overlap between predicted concentrations from estimated emissions with measured concentrations. Our analysis is, based on probabilistic analysis of measured outdoor air concentrations with those predicted from mass-balance models. Based on available information, we estimate the relative magnitude of emissions from four major sources of PAHs to outdoor air- (1) on-road motor vehicles, including light-duty gasoline vehicles and diesel-powered buses and medium and heavy duty trucks; (2) residential wood combustion; and (3) power generation from external combustion boilers. We use the CalTOX regional multimedia mass-balance model to evaluate our emissions estimates in rural and urban regions of the state of Minnesota, USA. We compare model estimates of outdoor PAH airborne concentrations with those reported by the Minnesota Children's Pesticide Exposure Study (MNCPES). With these measured concentrations we probabilistically evaluate our emissions and interpret the reliability of our emissions estimates for specific PAHs. The median estimates of our predicted outdoor air concentrations agree within an order of magnitude of measured concentrations. For four representative PAHs, we were able to obtain a reasonable degree of overlap between empirical and predicted distributions of outdoor air concentrations. Our combination of models, emissions estimates, and empirical concentration data estimate exposure in a manner that is more reliable than any of these tools alone. Thereby, we increase our confidence about our plausible ranges of emissions and predicted concentrations.

A 700 year sediment record of black carbon and polycyclic aromatic hydrocarbons near the EMEP air monitoring station in Aspvreten, Sweden  

SciTech Connect

In view of poor constraints on historical combustion emissions, past environmental loadings of black carbon (BC) and polycyclic aromatic hydrocarbon (PAH) were reconstructed from dated lake sediment cores collected 70 km south of Stockholm, Sweden. Compared to several dramatic variations over the recent 150 years, the preindustrial loadings were steady within {+-}50% through the entire medieval with BC fluxes of 0.071 g m{sup -2} yr{sup -1} and PAH fluxes of 6 g m{sup -2} yr{sup -1}. In the wood-burning dominated century leading up to the industrial revolution around 1850, increasing BC fluxes were leading PAH fluxes. BC fluxes reached their millennial-scale maximum around 1920, whereas PAH fluxes increased exponentially to its record maximum around 1960, 50-fold above preindustrial values. For 1920-1950, BC fluxes consistently decreased as PAH fluxes kept increasing. Coal and coke represented >50% of the Swedish energy market in the 1930s. Combined with sharply decreasing (1,7-)/(1,7{+-}2,6-dimethylphenanthrene), indicative of diminishing wood combustion, and decreasing methylphenanthrenes/phenanthrene, indicative of higher-temperature combustion (coal instead of wood), the sediment archive suggests that the relative BC/PAH emission factors thus are lower for coal than for wood combustion. For the first time, both BC and PAH fluxes decreased after 1960. This trend break is a testament to the positive effects of decreasing reliance on petroleum fuels and a number of legislative actions aimed at curbing emissions and by 1990, the loading of BC was back at preindustrial levels, whereas that of PAH were the lowest since the 1910s. However, for the most recent period (1990-2004) the BC and PAH fluxes are no longer decreasing. 55 refs., 3 figs.

Polycyclic aromatic hydrocarbons in road-deposited sediments, water sediments, and soils in Sydney, Australia: Comparisons of concentration distribution, sources and potential toxicity  

Science Journals Connector (OSTI)

Abstract Sixteen polycyclic aromatic hydrocarbons (PAHs) considered as priority environmental pollutants were analysed in surface natural soils (NS), road-deposited sediments (RDS), and water sediments (WS) at Kogarah in Sydney, Australia. Comparisons were made of their concentration distributions, likely sources and potential toxicities. The concentrations (mg/kg) in NS, RDS, and WS ranged from 0.40 to 7.49 (mean 2.80), 1.65 to 4.00 (mean 2.91), and 0.49 to 5.19 (mean 1.76), respectively. \\{PAHs\\} were dominated by relatively high molecular weight compounds with more than three fused benzene rings, indicating that high temperature combustion processes were their predominant sources. The proportions of high molecular weight \\{PAHs\\} with five or six fused benzene rings were higher in NS than in RDS, whereas the low molecular weight \\{PAHs\\} were higher in RDS. Concentrations of all \\{PAHs\\} compounds were observed to be the lowest in WS. The concentrations of most of the high molecular weight \\{PAHs\\} significantly correlated with each other in RDS and WS. All \\{PAHs\\} (except naphthalene) were significantly correlated in NS suggesting a common PAH source. Ratios for individual diagnostic \\{PAHs\\} demonstrated that the primary source of \\{PAHs\\} in WS and NS was of pyrogenic origin (combustion of petroleum (vehicle exhaust), grass, and wood) while in RDS it was petrogenic (i.e. unburned or leaked fuel and oil, road asphalt, and tyre particles) as well as pyrogenic. The potential toxicities of \\{PAHs\\} calculated using a toxicity equivalent quotient (TEQ) were all low but higher for NS compared to WS and RDS.

Compound class specific radiocarbon analysis (CCSRA) was performed for polycyclic aromatic hydrocarbons (PAHs) associated with airborne particulate matter (APM) with diameter {lt}10 {mu}m (PM{sub 10}) and {lt}1.1 {mu}m (PM{sub 1.1}) collected from a residential area of suburban Tokyo, Japan, and seasonal and particle-size radiocarbon variations were investigated. Source diagnostic isomer pair ratios indicated mixed contributions from petroleum combustion and from biomass and coal combustion to the PAHs in APM. The {Delta}{sup 14}C-PAHs in APM, ranging from -787 to -514{per_thousand}, indicated dominance of fossil fuel combustion. The {Delta}{sup 14}C of 5-6 rings (HMW) PAHs were higher than the 3-4 rings (LMW) species in both PM{sub 10} and PM{sub 1.1} samples. The {Delta}{sup 14}C of HMW-PAHs indicated greater biomass-burning contributions in summer than in winter and no apparent particle-size variation. Conversely, the {Delta}{sup 14}C of LMW species showed a greater contribution from fossil sources in summer and in larger particles (PM10). This finding could be tentatively attributed to the recondensation of fossil-PAHs vaporized from petroleum sources. A {Delta}{sup 14}C isotopic mass balance approach estimated that biomass burning contributes 17-45% of the PAH burden in suburban Tokyo, and that the increase in the biomass-PAH accounts for approximately 27% and 22% of winter-time elevation of LMW- and HMW-PAHs, respectively. These are far exceeding what is expected from the emission statistics for CO{sub 2} and combusted materials in Japan and emphasizing the importance of biomass-burning as a source of PAHs; which, in turn, demonstrates the utility and the significance of field-based source assessment by using CCSRA for an effective regulation of atmospheric pollution by PAHs. 37 refs., 3 figs., 2 tabs.

Aromatic-radical oxidation chemistry  

SciTech Connect

The research effort has focussed on discovering an explanation for the anomalously high CO{sub 2} concentrations observed early in the reaction sequence of the oxidation of cyclopentadiene. To explain this observation, a number of plausible mechanisms have been developed which now await experimental verification. One experimental technique for verifying mechanisms is to probe the reacting system by perturbing the radical concentrations. Two forms of chemical perturbation of the oxidation of cyclopentadiene were begun during this past year--the addition of NO{sub 2} and CO to the reacting mixture.

Measurement and correlation of phase equilibria for (water+aromatic hydrocarbon) binary mixtures at T=(573 to 623)K using microfluidic mixing  

Science Journals Connector (OSTI)

(Vapour+liquid) and (liquid+liquid) equilibria for (water+p-xylene) and (water+decalin) mixtures at T=(573 to 623)K were measured by a flow type apparatus with microfluidic system. The liquidliquid slug flows in the microfluidic system were used for mixing of water and hydrocarbon due to high mass transfer between two liquid phases. The formations of the liquidliquid slugs for (water+p-xylene) system were studied by changing the flow rate. The results of the liquidliquid slug formations at hydrocarbon and water rich compositions were used for the measurements for (vapour+liquid) and (liquid+liquid) equilibria, respectively. It was found that the phase equilibria using the apparatus with the microfluidic system can be measured in a short residential time (1.6 to 3.2)min. The experimental results of the phase equilibria for (water+p-xylene) and (water+decalin) systems give that the regions of the (vapour+liquid) and (liquid+liquid) equilibria for both mixtures reduce with the increasing temperature. The mixture of (water+decalin) at T=(583 to 623)K forms the two phase regions of the (vapour+liquid) and (liquid+liquid) equilibria larger than those for (water+p-xylene) mixture. The experimental data of the phase equilibria obtained in this work were correlated with PengRobinsonStryjekVera equation of state. The correlated results of the (liquid+liquid) equilibria for both systems represent the experimental data. For (vapour+liquid) equilibria, the results give the qualitative representations in the shape of the two phase region for both mixtures.

Using bifunctional organic ligand 5-(4-imidazol-1-yl-phenyl)-2H-tetrazole (HL) and different aromatic carboxylates as secondary ligands, four novel metal-organic coordination polymers, [Zn(L)(1,4-bdc){sub 0.5}] (1), [Zn{sub 1.5}(L)(2,5-pydc)] (2), [Zn(HL)(1,2,4,5-btec){sub 0.5}] (3), and [Cd(HL)(1,2,4,5-btec){sub 0.5}] (4) (1,4-bdc, 1,4-benzenedicarboxylate; 2,5-pydc, 2,5-pyridinedicarboxylate; 1,2,4,5-btec, 1,2,4,5-benzenetetracarboxylate) have been successfully synthesized and analyzed. Compound 1 features the 2D [Zn(L)]{sub n} layers built by ?{sub 3}-L bridging ligands and Zn(II) ions, which are further linked by pillared 1,4-bdc{sup 2?} ligands to form a 2-fold interpenetrating dmc framework. The 3D network of compound 2 can be simplified as a rare 2-nodal (3,6)-connected rtl (rutile) topology. Compound 3 possesses a 2D layer structure which is accomplished by connecting ladder-chains to L ligands. Compound 4 exhibits 2D [Cd(1,2,4,5-btec)] layers with infinite CdOCd rods and the adjacent 2D networks are further pillared by L with terminal bidentate coordination mode to generate the final 3D structure. The solid-state luminescent studies show that compounds 14 display intense fluorescent emissions. - Graphical abstract: Using bifunctional organic ligand 5-(4-imidazol-1-yl-phenyl)-2H-tetrazole (HL) and different aromatic carboxylates as secondary ligands, four novel metal-organic coordination polymers have been obtained.
