Zeolites, groups of minerals comprising of hydrated aluminosilicates, are known to be highly promising materials for a number of applications. For instance, they can be used as catalysts, cation exchangers and molecular sieves.
(PhysOrg.com) -- Conventional scientific wisdom says that the interatomic forces between ions that control high-temperature processes such as melting are insensitive to the heating of the electron "glue" that binds the ions ...
