Supervariate Ceramics: Demineralization via Gelation in Neutral Nontoxic Solutions
Demineralization is essential in various fields, from ocean acidification to orthopaedics. Currently, demineralization is generally ascribed to etching by corrosive acids. Herein, the “supervariate” strategy for the demineralization of calcite (the most abundant biomineral on Earth, and a major comp...
