Advanced Science, EarlyView.Supported liquid alloys of gallium and platinum with different metal‐to‐metal ratios are used in propane dehydrogenation. The catalytic performance is correlated with spectroscopic insight gained from pair distribution function (PDF) studies combined with density functional theory (DFT). Abstract The supported catalytically active liquid metal solution

A new class of non-monotone finite difference (FD) approximation methods for approximating solutions to non-degenerate stationary Hamilton-Jacobi problems with Dirichlet boundary conditions is proposed and analyzed. The new FD methods add a high order correction to the Lax-Friedrich's method while utilizing a novel cutoff to preserve the convergence ...

Morphology Formation Pathways in Solution‐Processed Perovskite Thin Films
Advanced Science, EarlyView.A geometrical model is developed that deals with the effect of the interplay between solvent evaporation and crystal growth on the dry film morphology. The possible film formation mechanisms and the resulting morphologies are investigated, depending on the processing conditions. Eleven formation pathways are found leading to four distinct morphologies.
