Since their constituent minerals are crystallized from molten material, igneous rocks are formed at high temperatures.
Closely related are the faint blue luminescence observable when adhesive tapes are stripped from a roll, and the luminescence exhibited when strontium bromate and some other salts are crystallized from hot solutions.
After droplet etching, the nanohole openings are surrounded by walls that are crystallized from droplet material and may act as quantum rings [19, 22 25].
A new phase of dimesityliron has been crystallized from diethylether; the crystal structure shows a dinuclear complex with co-crystallized solvent.
