“…Lee et al found that the compound formed by calcium and phosphorus deposition could significantly improve the adhesion and proliferation of bone marrow mesenchymal stem cells [41]. Moreover, Sharkov et al reported that the osteoblasts were cocoltured with compound formed by calcium and phosphorus deposition, the results of which showed that the compound could obviously upregulate the expression level of osteogenesis-related genes of the cells [42]. So, the increased calcium and phosphorus deposition could promote osteogenic behaviours of cells.…”

Titanium (Ti) is widely used in oral implants. However, there is still a challenge to promote the osseointegration of bone tissue on the surface of Ti. To solve this problem, we prepared novel gradient nanostructured (GNS) Ti and studied the effect of GNS on the adhesion, proliferation, and apoptosis of MG63 cells in vitro. The results demonstrated that the GNS Ti promoted the adhesion effect and proliferation of MG63 cells better than the annealed Ti, while the ability of GNS Ti to inhibit cell apoptosis was better than that of the annealed Ti, the preliminary mechanism of which indicated by this study might be the enhanced mineralization capacity, protein adsorption ability, and hydrophilicity of the GNS Ti due to its specific nanostructure which improved the cell behaviours. The results in this study provide the theoretical and experimental foundations for the applications of GNS Ti in dental implants and joint replacements.

“…At the same time, the mechanisms of ore-forming processes are the subject of heated discussions. In particular, the models of gravitational accumulation of magnetite (titaniferous magnetite) and ilmenite [6,7], ore melt liquation [8][9][10][11][12] are actively developed, and "combination" models, in which the formation of Fe-Ti mineralization is caused by a special mechanism of silicate minerals crystallization, are actively discussed [13].…”

Materials on geochemistry and ore Fe-Ti-Cr mineralization of rocks composing layered (stratified) bodies of the western slope of the Southern Urals are presented. A detailed analysis showed similarity in the redistribution of REE, noble metals, and Fe-Ti-Cr mineralization of practically all parameters in rocks of the Misaelga and Kusin-Kopan complexes. It has been established that the parameters of metamorphism, which influenced components redistribution in Fe-Ti-Cr minerals of the layered complexes, correspond to Misaelga – T = <550-750 °С, P = 0.1-2.8 kbar, Kusin-Kopan – T = <550-630 °С, P = 0.3-0.7 kbar, and Shuidinsky complexes – T = <550-760 °С, P = 0.5-2.5 kbar. The result of modelling the melt crystallization process showed that the Kusin-Kopan complex is an intrusive body with an ultramafic horizon in the idealized cross-section. Due to collisional processes, the lower part of the intrusion has been detached from the upper part. The proposed structure of the Kusin-Kopan complex sharply increases its prospects for such types of minerals as platinum group minerals + sulphide copper-nickel mine-ralization and/or chromites.
