Title: Effect of polarization forces on carbon deposition on a non-spherical nanoparticle. Monte Carlo simulations [Effect of polarization forces on atom deposition on a non-spherical nanoparticle. Monte Carlo simulations]

Abstract

Trajectories of a polarizable species (atoms or molecules) in the vicinity of a negatively charged nanoparticle (at a floating potential) are considered. The atoms are pulled into regions of strong electric field by polarization forces. The polarization increases the deposition rate of the atoms and molecules at the nanoparticle. The effect of the non-spherical shape of the nanoparticle is investigated by the Monte Carlo method. The shape of the non-spherical nanoparticle is approximated by an ellipsoid. The total deposition rate and its flux density distribution along the nanoparticle surface are calculated. As a result, it is shown that the flux density is not uniform along the surface. It is maximal at the nanoparticle tips.

Effect of monomer sequences on conformations of copolymers grafted on spherical nanoparticles: A Monte Carlo simulation study

Journal Article Seifpour, Arezou ; Spicer, Philip ; Nair, Nitish ; ... - Journal of Chemical Physics

Functionalizing nanoparticles with organic ligands, such as oligomers, polymers, DNA, and proteins, is an attractive way to manipulate the interfacial interactions between the nanoparticles and the medium the particles are placed in, and thus control the nanoparticle assembly. In this paper we have conducted a Monte Carlo simulation study on copolymer grafted spherical nanoparticles to show the tremendous potential of using monomer sequence on the copolymers to tune the grafted chain conformation, and thus the effective interactions between copolymer grafted nanoparticles. We have studied AB copolymers with alternating, multiblock, or diblock sequences, where either A monomers or B monomers havemore »« less

Monte Carlo Micro-Solvation Simulations For Excited States using a Mixed-Hamiltonian Model with Polarizable and Vibrating Waters: Application to the Blueshift of the H2CO (1)(pi(*)<-n) Excitation.

Journal Article Kawashima, Y ; Dupuis, Michel ; Hirao, Kimihiko - Journal of Chemical Physics

The previously formulated Quantum Mechanical (QM)/Molecular Mechanical (MM) model applicable to micro-solvated solute excited state, the QM/MM-pol-vib/CAV model, has been combined with a Monte Carlo averaging scheme to derive the averaged properties of the solvated solutes. The methodology was applied to the electronic 1(p*n) excitation of formaldehyde in water. We first performed Monte Carlo MM/MM calculations to generate the water configurations. Then, we chose 400 configurations for the QM/MM excitation energy calculations. Finally, we carried out Complete Active Space Self-Consistent Field (CASSCF) calculations to derive the average excitation energy.

Monte carlo simulations of segregation in Pt-Re catalyst nanoparticles

Journal Article Wang, Guofeng ; Van Hove, M A ; Ross, P N ; ... - Journal of Chemical Physics

We have investigated the segregation of Pt atoms to the surfaces of Pt-Re nanoparticles using the Monte Carlo method and Modified Embedded Atom Method potentials that we have developed for Pt-Re alloys. The Pt75Re25 nanoparticles (containing from 586 to 4033 atoms) are assumed to have disordered fcc configurations and cubo-octahedral shapes (terminated by {l_brace}111{r_brace} and {l_brace}100{r_brace} facets), while the Pt50Re50 and Pt25Re75 nanoparticles (containing from 587 to 4061 atoms) are assumed to have disordered hcp configurations and truncated hexagonal bipyramidal shapes (terminated by {l_brace}0001{r_brace} and {l_brace}101 {bar 1}{r_brace} facets). We predict that due to the segregation process the equilibrium Pt-Remore »« less

Monte Carlo Simulations of Segregation in Pt-Ni Catalyst Nanoparticles

Journal Article Wang, Guofeng ; Van Hove, Michel A ; Ross, Philip N ; ... - Journal of Chemical Physics

We have investigated the segregation of Pt atoms in the surfaces of Pt-Ni nanoparticles, using Modified Embedded Atom Model potentials and the Monte Carlo method. The nanoparticles are assumed to have disordered fcc configurations at two fixed overall concentrations (50 at. percent Pt and 75 at. percent Pt). We use four kinds of nanoparticle shapes [cube, tetrahedron, octahedron, and cubo-octahedron] terminated by {l_brace}111{r_brace} and {l_brace}100{r_brace} facets to examine the extent of the Pt segregation to the nanoparticle surfaces and determine the equilibrium structures of Pt-Ni nanoparticles at T=600 K. The model particles contain between 560 and 4631 atoms (particle sizemore »« less

Non-Gaussian halo mass function and non-spherical halo collapse: theory vs. simulations

Journal Article Achitouv, Ixandra E. ; Corasaniti, Pier Stefano, E-mail: Ixandra.Achitouv@obspm.fr, E-mail: Pier-Stefano.Corasaniti@obspm.fr - Journal of Cosmology and Astroparticle Physics

The mass distribution of dark matter halos is a sensitive probe of primordial non-Gaussianity (NG). We derive an analytical formula of the halo mass function by perturbatively computing excursion set path-integrals for a non-Gaussian density field with non-vanishing skewness, f{sub NL}. We assume a stochastic barrier model which captures the main features of the ellipsoidal collapse of halos. Contrary to previous results based on extensions of the Press-Schechter formalism to NG initial conditions, we find that the non-spherical collapse of halos directly alter the signature of primordial NG. This points toward a potential degeneracy between the effect of primordial non-Gaussianitymore »« less
