In chemistry of inorganic crystals, the octacalcium phosphate (OCP) is an apatite based crystals and having a hydrated layers which used in producing needle or plate-shaped hydroxyapatite (HAP) nanocrystals. Although, prepared by dissolution precipitation reaction. These reaction led to hexagonal HAP nanocrystals formation under hydrothermal condition from OCP at 180 for 3 hours with pH solutio...

This article presents the results of a study radiation-induced defects in various synthetic calcium phosphate (CP) powder materials (hydroxyapatite—HA and octacalcium phosphate—OCP) by electron paramagnetic resonance (EPR) spectroscopy at X, Q, W-bands (9, 34, 95 GHz for microwave frequencies, respectively). Currently, CP are widely used orthopedics dentistry owing to their high biocompatibilit...

Soil microorganisms directly participate in phosphorus (P) cycle, which turn affects crop yield and quality. However, how biological chemical parameters respond to mineral P fertilizer application rates rhizosphere soil remains unclear. Here, a pot experiment was conducted investigate the effects of different (0, 60, 120, 300 kg P2O5 ha−1) on properties bacterial community maize Mollisol. With ...
