Reactive Molecular Dynamics

ABSTRACTA reactive molecular dynamics simulation study on the structure, energetics, and chemistry of alkanethiolated gold cluster is presented. Through very recent reactive molecular dynamics force-fields developed by Järvi et al. [1], chemical reactions of alkanedithiolates and star-like shape gold nanoparticles are studied throughout octanedithiolates and stellated cuboctahedral gold clusters models [2] at room temperature. Structure, energetics, reactants, and some products of the reactions are preliminarily analyzed up to 25 ps. In general, preliminary results of this work are in agreement with those reported in the review by Love et al. [3].

The interaction of the shuffle 60° dislocation with a regular chain of hexavacancies was investigated via the molecular dynamics simulation with Stillinger-Weber potential. The results show that an attraction exists between the shuffle 60° dislocation and hexavacany. The attraction energy is dependent obviously upon the hexavacancy concentration. The dislocation can overcome the pinning of vacancies under a critical resolved shear stress, and a linear relationship is found between the critical stress and hexavacancy concentration.
