Abstract Here, we present a comprehensive study on atomic-scale in-situ biasing/heating scanning transmission electron microscopy ((S)TEM) of Al-amorphous SiO 2 –SiC interface. The investigation includes electrical, chemical, and structural analysis the interface at different temperatures (25–600 °C). results show that ~ 500 °C electrical (three-orders magnitude resistivity drop), chemical (dis...

We study the dynamics and arrest of two coalescing sessile yield-stress drops. Surprisingly, we find that height bridge evolves similar to a Newtonian fluid. The arrested final coalesced shape is described by balance between capillary pressure yield stress, which predicted from viscoplastic lubrication theory.

We discuss, at the mean-field level, the asymptotic shape of the reaction fronts in the general nA+mB → C reaction-diffusion processes with initially separated reactants, thus generalizing to arbitrary reaction-order kinetics the work done by Gálfi and Rácz for the case n = m = 1. Consequences for the formation of Liesegang patterns are discussed. PACS. 82.20.Mj Nonequilibrium kinetics – 82.20....
