Graphite molecular geometry
WebThe dynamics of bulk liquid para-cresol from 340–390 K was probed using a tandem quasielastic neutron scattering (QENS) and molecular dynamics (MD) approach, due to its relevance as a simple model component of lignin pyrolysis oil. QENS experiments observed both translational jump diffusion and isotropic rotation, with diffusion coefficients ranging … WebAug 28, 2024 · Fractal structures have been conjectured in both linear and circular geometry [14,27,28]. Molecular dynamics simulations were performed to study the diffusion of Thouy and Jullien fractal aggregates as a function of their mass and fractal dimension. The diffusion coefficient of a fractal aggregate was found to vary linearly with the inverse …
