Page 4: Research news on Molecular dynamics

Molecular dynamics is a computational simulation technique in which the time evolution of a molecular system is obtained by numerically integrating Newton’s equations of motion for atoms or coarse-grained particles under a specified interaction potential, typically defined by a force field. It provides atomistic or mesoscopic trajectories from which thermodynamic, structural, and kinetic properties can be derived. Molecular dynamics is widely used to study conformational dynamics, solvation, transport, and reaction pathways in systems ranging from small molecules to biomacromolecules and materials, often employing ensembles (NVE, NVT, NPT) and algorithms for temperature and pressure control, long-range electrostatics, and constraint handling.

Making the structure of 'fire ice' with nanoparticles

Cage structures made with nanoparticles could be a route toward making organized nanostructures with mixed materials, and researchers at the University of Michigan have shown how to achieve this through computer simulations.

Biomolecular sliding at the nanoscale

In organisms whose cells have a nucleus, like plants and animals, the basic packaging units of DNA are the so-called nucleosomes. A nucleosome consists of a segment of DNA wound around eight proteins known as histones. Gene ...

Getting warmer: Improving heat flux modeling

Scientists at Osaka University have simulated heat transport at the smallest scales using a molecular dynamics computer simulation. By studying the motions of the individual particles that make up the boundary between a solid ...
