Electrolytes and Interphases in Sodium‐Based

Yu et al. [] studied the Na 3 P 1− x As x S 4 (0 ≤ x ≤ 1) binary compounds obtaining a conductivity of 1.46 mS cm −1 at RT for x = 0.38 (i.e., Na 3 P 0.62 As 0.38 S 4), which is higher than the pure Na 3 PS 4 and Na 3 SeS 4 compounds.

graphite electrodes properties

2019/10/20Graphite Electrodes: Since graphite is the preferred electrode material for 90% of all sinker EDM applications we are going to concentrate on understanding its properties. Due to its unique properties iso-molded graphite is the ideal material of choice for sinker

Lightning Strike Protection For Composite Structures

2006/7/1General aviation aircraft, large commercial jets and wind turbines are vulnerable to lightning strike. FAA-certified aircraft, for example, are typically struck once or twice a year. Unlike their metal counterparts, composite structures in these applications do not readily conduct away the extreme electrical currents and electromagnetic forces generated by lightning strikes.

Polyacrylonitrile

Polyacrylonitrile (PAN), also known as polyvinyl cyanide and Creslan 61, is a synthetic, semicrystalline organic polymer resin, with the linear formula (C3H3N)n. Though it is thermoplastic, it does not melt under normal conditions. It degrades before melting. It melts above 300 C if the heating rates are 50 degrees per minute or above.[2
