The melting of a 64 ion microcrystal of KCI was studied by means of a molecular dynamics computer simulation. We used a central pair interaction with an inverse power law repulsion. The thermodynamics, kinetic and structural properties such as melting temperature, latent heat, mean square displacement, diffusion constant, radial distribution function and bond angle distribution are calculated. ...

Based on the fact the manipulation of fine nanoclusters calls for more precise modeling, the aim of this paper is to conduct an atomistic investigation for interaction analysis of particle-substrate system for pushing and positioning purposes. In the present research, 2D molecular dynamics simulations have been used to investigate such behaviors. Performing the planar simulations can provide a ...

Over the past years, two-dimensional materials such as graphene, phosphorene, silicene, and boron-nitride have attracted the attention of many researchers. After the successful synthesis of graphene, due to its many new applications, researches began to produce nanosheets from other elements, and among these elements, boron was one of the options. In the periodic table of elements, boron is ahe...

In this study the operations of melting of Au15Ag40 nanoalloy have been studied using the molecular dynamic simulations through the Gupta multiparticle potential and the nonergodicity of simulations is eliminated by the multiple histogram method. The melting characteristics are determined by the analysis of variations in the potential energy. The calculations indicate that the melting of Au15Ag...

The overall aim of this study is to calculate some water properties in the single wall carbon naotubes (SWCNT) and compare them to the bulk water properties to investigate the deviation of water properties inside the SWCNT from those in the bulk. Here some physical and transport properties of water molecules in the single wall carbon nanotube were reported by performing molecular dynamics (MD) ...

In the current research, thermal conductivity of magnetite (Fe3O4) has been calculated using molecular dynamic simulation. The rNEMD Molecular Dynamics Method provided in the LMMPS package is used for the simulation of the thermal conductivity. The effects of magnetite layer size and temperature on the thermal conductivity have been investigated. The numerical results have...

The effect of sample size on the melting parameter of simulated potassium chloride microcrystal is investigated by molecular dynamics simulation. The size of microcrystal is varied from 8 to 4096 ions. The increase in melting temperature with sample size was found to be in good agreement with the theory.

Integrated on-they data analysis and image synthesis is one of the most dominant challenges on modern volume visualization tools. Since volume visualiza-tion algorithms are themself computationally complex and memory intensive there is hardly a chance to eeciently integrate data analysis tools on standard single processor architectures. The development and spreading of multiprocessor systems wi...

We have developed atomic-scale material models capable of melting, crystallization and amorphization. These models feature molecular dynamics governed by Langevin equations of motion in which particle interact through attractive covalent forces and short-range repulsion forces. Also, we present an interactive virtual visualization tool for the simulation of atomic scale material behavior. An ap...
