Advanced Optical Materials, EarlyView.Germanium (Ge) all‐dielectric metasurfaces can be leveraged to strongly enhance the radiative emission from Ge layers grown on silicon‐on‐insulator substrates by industry‐standard processes. At room‐temperature, the narrowband photoluminescence (PL) intensity is enhanced by a factor ∼40× with respect to unstructured films.

Effects of Sliding Conditions on Improvement of Lubrication with Micro Pits in Metal Forming.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 2000 A series of experiments have been conducted using a rolling-type tribometer to investigate the mechanism and lubricating effects of the outflow behavior of lubricant trapped in a pit. Experiments using aluminum and mild steel sheets with regularly arranged pits showed that lubricant flows out along the friction stress direction and moves larger ...

Flexoelectricity in Photoconversion: Fundamentals, Materials, and Outlooks
Advanced Science, EarlyView.Mechanical bending of a flexible cantilever induces a strain gradient in the photoactive material. The resulting flexoelectric field couples with photovoltaic and photoconductive effects, modulating charge generation, separation, and collection. A comparative analysis of oxide perovskites, halide perovskites, and two‐dimensional materials is presented,
