✦ Synopsis

The molecular dynamics (MD) simulations of crystallisation and glass formation in liquid lead have been performed. Two series of calculations are presented. 1. Isochoric quenches down to 1 K of liquid densified and rarefied lead at various cooling rates; 2. Isothermal (at 600K) compression and decompression at various compression rates. The resulting structures at 1K are analysed within the stochastic geometry methods. The changes of the potential energy, and of the diffusion coefficient during the pressure induced solidification are discussed.

In this exploratory study, the methods of molecular dynamics and Brownian dynamics have been used to investigate the dynamics of ring formation in a simple, idealised, flexible molecule. Particular attention has been paid to the formation and persistence of the bond responsible for ring closure. The

The present study investigates bubble nucleation in liquid oxygen with dissolved impurities (nitrogen or helium molecules) using molecular dynamics simulations. When the mole fraction of impurities is 0.05, there is a fundamental difference in the bubble nucleation mechanism between the two dissolve
