Origin of the non-linear elastic behavior of silicate glasses
Zhen Zhang, Simona Ispas, Walter Kob
For small tension the response of a solid to an applied stress is given by Hooke's law. Outside this linear regime the relation between stress and strain is no longer universal and…
Connecting packing efficiency of binary hard sphere systems to their intermediate range structure
Houfei Yuan, Zhen Zhang, Walter Kob +1
Using computed x-ray tomography we determine the three dimensional (3d) structure of binary hard sphere mixtures as a function of composition and size ratio of the particles, q. Us…
Effective boundary conditions for dynamic contact angle hysteresis on chemically inhomogeneous surfaces
Zhen Zhang, Xianmin XU
Recent experiments (Guan et al. 2016a,b) showed many interesting phenomena on dynamic contact angle hysteresis while there is still a lack of complete theoretical interpretation. I…
\textit{Ab initio} lattice thermal conductivity of MgSiO across perovskite-postperovskite phase transition
Zhen Zhang, Renata M. Wentzcovitch
Lattice thermal conductivity () of MgSiO postperovskite (MgPPv) under the Earth's lower mantle high pressure-temperature conditions is studied using the phonon quasipa…
First principles study of the surface of silica and sodium silicate glasses
Zhen Zhang, Walter Kob, Simona Ispas
We use \textit{ab initio} molecular dynamics simulations to investigate the properties of the dry surface of pure silica and sodium silicate glasses. The surface layers are defined…
