Gallium
(Preview)
Gallium is a chemical element that has the symbol Ga and atomic number 31. Elemental gallium does not occur in nature, but as the gallium(III) salt in trace amounts in bauxite and zinc ores. Gallium was discovered spectroscopically by Paul Emile Lecoq de Boisbaudran in 1875 by its characteristic sp...

Quantum crystal
(Preview)
Exotic Quantum crystal discovered Nature knows two opposite types of solids: one that emerges upon compression from a liquid and a second that appears if the pressure on a liquid is reduced. While the former is typical for substances in our everyday life the latter occurs for example in a dense quant...
