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 decom

✦ Synopsis
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 effects of temperature and the influence of a "stochastic solvent" on the stability of the conformational structures have also been examined. Techniques for identifying quasi-stable structures in a simulation are outlined.

## Abstract We have developed an algorithm for sampling the conformational space of large flexible molecules in solution, which combines the molecular dynamics (MD) method and the three‐dimensional reference interaction site model (3D‐RISM) theory. The solvent‐induced force acting on solute atoms w
