In this paper, a varactor with metal–semiconductor–metal diodes on top of the (NH 4) 2 S/P 2 S 5-treated AlGaN/GaN two-dimensional electron gas epitaxial structure (MSM-2DEG) is proposed to the surge protection for the first time. The sulfur-treated MSM-2DEG varactor properties, including current–voltage (I–V), capacitance–voltage (C–V), and frequency response of the proposed surge protection c...

Metal oxide surge arresters are used to protect medium and high voltage systems and equipment against lightning and switching overvoltages. Measurements of the residual voltage of the metal oxide surge arresters indicate dynamic characteristics with the residual voltage to increase as the current front time descends and the residual voltage to reach its maximum, before the arrester current reac...

The reliable production of high-quality lithium-ion battery components still poses a challenge, which must be met to cope with their rising demand. One key step in the sequence is process cell-internal contacting, during electrode carrier foils anode and cathode are joined arrester. This usually done ultrasonic or laser beam welding. Both joining processes, however, show limitations concerning ...

A design of peel-speed sensitive flexible fastener was proposed based on a novel modified polyurethane. Taking the microtrichia head-arrester system lestes barbarous as bionic prototype, structure micro protuberance designed self-mating type with hemispherical caps. Considering nonlinearities contact behavior and material property, micromechanical model typical interlocking element is establish...
