DOI: 10.1016/j.actamat.2020.05.044
Abstract: Abstract Phase-change materials (PCMs) are already commercialized in optical and non-volatile memory devices. Yet, the dynamics of atomic rearrangement processes and their temperature dependence, which govern their ultrafast switching, are still not fully understood. Here… read more here.

Abstract: We derive a theoretical model for the nonequilibrium stress in a flowing colloidal suspension by tracking the motion of a single embedded probe. While Stokes-Einstein relations connect passive, observable diffusion of a colloidal particle to… read more here.

DOI: 10.1126/sciadv.aat8632
Abstract: Failure of classic equation linking diffusion and viscosity points to new thinking on switch kinetics of phase-change materials. The dynamic properties of liquid phase-change materials (PCMs), such as viscosity η and the atomic self-diffusion coefficient… read more here.
