Supervariate ceramics: biomineralization mechanism

The Molecular Mechanism of Pearl Biomineralization

In the artificial pearl industry, the epithelial cell of mantle grafting proliferates to form the pearl sac and secret organic matrix to guide pearl biomineralization. This article summarized the process of pearl formation, the involvement of matrix proteins in calcium carbonate (CaCO3) deposition and the genetic contribution of saibo in pearl formation. At last summarizes the existing issues a...

On the Mechanism of Microwave Flash Sintering of Ceramics

The results of a study of ultra-rapid (flash) sintering of oxide ceramic materials under microwave heating with high absorbed power per unit volume of material (10-500 W/cm³) are presented. Ceramic samples of various compositions-Al₂O₃; Y₂O₃; MgAl₂O₄; and Yb(LaO)₂O₃-were sintered using a 24 GHz gyrotron system to a density above 0.98-0.99 of the theoretical value in 0.5-5 min without isothermal...

Biomineralization induced by Myxobacteria

Myxococcus xanthus is a Gram negative, non-pathogenic, common soil bacterium that belongs to the δsubdivision of the Proteobacteria. According to the data, it is demonstrated that, depending on the chemistry of the culture media, M. xanthus is able to induce the formation of phosphates (struvite, schertelite, newberyite), carbonates (calcite, Mg-calcite, vaterite) and sulfates (barite, taylorit...
