WebMolecular dynamics (MD) is a computer simulation method for analyzing the physical movements of atoms and molecules.The atoms and molecules are allowed to interact for a fixed period of time, giving a view of the dynamic "evolution" of the system. In the most common version, the trajectories of atoms and molecules are determined by numerically … WebT1 - Reactive molecular dynamics simulation on the disintegration of Kapton, POSS polyimide, amorphous silica, and teflon during atomic oxygen impact using the reaxff reactive force-field method.

WebMay 4, 2010 · We report our study of a silica-water interface using reactive molecular dynamics. This first-of-its-kind simulation achieves length and time scales required to investigate the detailed chemistry of the system. Our molecular dynamics approach is based on the ReaxFF force field of van Duin et al. [J. Phys. Chem. A 107, 3803 (2003)]. WebJan 19, 2024 · New concepts Molecular dynamics (MD) simulation is a major asset in polymer modeling. Nevertheless, constructing close-to-equilibrium initial structures (i.e., a key to achieve realistic polymer models) is a great challenge.Due to the lack of a standard protocol to build up close-to-equilibrium initial structures, most existing MD methods can … WebReactive Molecular Dynamics In a RMD study of nonequilibrium reaction kinetics in NM, HMX, and PETN under direct heating at various rates and irradiation with electric fields of various frequencies and strengths, the equilibrium picture was found to hold only for … The molecular dynamics is probably most complex in amorphous melts close to the … Lignin of different chemical structures and composition with different properties can … 1.1.
