Simulation Study on Charge Distribution Characteristics of Gas–Solid Interface Based on Improved Saturation Current Density Method

工程科学与技术
Free charge accumulation on the surface of solid insulation under direct current (DC) voltage distorts the electric field distribution on the insulator’s surface, affecting discharge behavior, such as creeping flashover.

Strong Lead‐Free Bioinspired Piezoceramics for Durable Energy Transducers

Advanced Functional Materials, EarlyView.
We fabricated brick‐and‐mortar lead‐free piezoceramics with Bi0.5Na0.5TiO3 monocrystal platelets as bricks and amorphous silica as mortar. The alignment of the bricks and the presence of the amorphous silica led to anisotropic residual stresses. These residual stresses increase the samples toughness, strength and durability while the brick alignment ...
