Recent progress in the simulation of diffusion associated with hollow and Bi-metallic nanoparticlesMurch, Graeme E., Evteev, Alexander V., Levchenko, Elena V., Belova, Irina V. 26 November 2015 (has links) (PDF)
In this paper, we review the recent understanding gained by kinetic Monte Carlo and molecular dynamics simulation and related theory of the diffusion processes involved in 1) the formation and later shrinkage of hollow nanoparticles and 2) the formation of segregated bi-metallic nanoparticles.

Surface diffusion of particles over bivariate trap latticesTarasenko, Alexander, Jastrabik, Lubomir 14 December 2015 (has links) (PDF)
We investigate the diffusion of particles on heterogeneous lattices with two kinds of nonequivalent sites. General analytical expressions for the chemical and jump diffusion coefficients have been derived in the case of strong inhomogeneity. We have calculated coverage dependencies of the diffusion coefficients and other necessary thermodynamic quantities for some representative values of the lateral pairwise interaction between the particles. The analytical data have been compared with the numerical data obtained by the kinetic Monte Carlo simulations. Almost perfect agreement between the respective results has been found.

Investigations of heterogeneous diffusion based on the probability density of scaled squared displacements observed from single molecules in ultra-thin liquid filmsHeidernätsch, Mario, Täuber, Daniela, Borczyskowski, Christian von, Radons, Günter 14 December 2015 (has links) (PDF)
Diffusion processes in ultra-thin liquid films observed by video microscopy reveal a complex behavior.
In contrast to homogeneous diffusion, dynamic and static heterogeneities are induced by layer transitions and compartments with differing diffusion coefficients, respectively. The objective of this research is the detection and distinction of such heterogeneities as well as an analysis of the underlying processes. Hence, a new method is proposed establishing a probability density of scaled squared displacements. This probability density allows for a simple and well-defined calculation of time-dependent diffusion coefficients and its fluctuations. Furthermore, by simulating a heterogeneous diffusion process these results are verified and compared to mean square displacement calculations. By means of the simulated probability density data, their dependency on the parameters is illustrated and further implications are pointed out.
