Nicotine
The name nicotine comes from the name of the French physician Jean Nicot, who recommended tobacco as a medicine in the 16th century.
Nicotine was first isolated in 1828, and its chemical structure was discovered in 1843. Nicotine was first obtained through a chemical process in 1904.
Silver
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.
