Huge amounts of high-energy charged particles (mainly protons and electrons) are then ejected from t ...

Silver is also used in the production of electrical and electronic equipment, high-voltage contacts, solder, high-capacity silver-zinc and silver-cadmium batteries, and photovoltaic cells.
Silver is the only catalyst that allows the conversion of ethylene into ethylene oxide, which then undergoes hydrolysis to produce ethylene glycol, used to produce polyester.
Moon
Selenographic coordinates are used to determine coordinates on the lunar surface.
