A wide variety of neptunium sulfide compounds have been characterized, including the pure sulfide compounds NpS, NpS 3, Np 2 S 5, Np 3 S 5, Np 2 S 3, and Np 3 S 4. Of these, Np 2 S 3 , prepared by reacting NpO 2 with hydrogen sulfide and carbon disulfide at around 1000 °C, is the most well-studied and three allotropic forms are known.
A coin pusher machine typically also has small gaps at the sides of the playfield where coins can fall, and coins that fall here are the operator's profits. In addition to the coins, operators often add toys, jewelry, dollar bills, and other items on top of the coins on the playfield, to entice players with a chance to win not only coins but ...

The World of Chemistry is a television series on introductory chemistry hosted by Nobel Prize-winning chemist Roald Hoffmann.The series consists of 26 half-hour video programs, along with coordinated books, which explore various topics in chemistry through experiments conducted by Stevens Point emeritus professor Don Showalter the "series demonstrator" [1] and interviews with working chemists ...
Colloidal gold is a sol or colloidal suspension of nanoparticles of gold in a fluid, usually water. [1] The colloid is coloured usually either wine red (for spherical particles less than 100 nm) or blue-purple (for larger spherical particles or nanorods). [2]
