PREPARATION OF SILICON-SUBSTITUTED BETA-TRICALCIUM PHOSPHATE BY THE POLYMERIZED COMPLEX METHOD

CALCIUM PHOSPHATE CEMENT: STUDY OF (BETA-TRICALCIUM PHOSPHATE, DICALCIUM PHOSPHATE AND CALCIUM CARBONATE SYSTEM

Calcium phosphate cements (CPCs), using B-tricalcium phosphate (ß-TCP, Ca3 (P04)2), dicalcium phosphate (DCP, CaHP04), calcium carbonate (Ca CO3), and hydroxylapatite (HAp, Ca10(P04)6(OH)2) as powder cement and disodium hydrogen phosphate (Na2HP04) solution as liquid component were prepared. After mixing the powder and liquid constituents, injectable and self-setting calcium phosphate cements (...

Preparation of injectable 3D-formed beta-tricalcium phosphate bead/alginate composite for bone tissue engineering.

A novel, injectable bone tissue engineering material was developed that consisted of beta-tricalcium phosphate (beta-TCP) beads as the solid phase and alginate as the gel phase. To prepare the instantaneously formed composite scaffold, an aqueous calcium chloride solution was dried on the surface of beta-TCP beads and crosslinked with an alginic acid sodium solution, thereby forming stable beta...

Hydrogen-substituted β-tricalcium phosphate synthesized in organic media

β-Tricalcium phosphate (β-TCP) platelets synthesized in ethylene glycol offer interesting geometries for nano-structured composite bone substitutes but were never crystallographically analyzed. In this study, powder X-ray diffraction and Rietveld refinement revealed a discrepancy between the platelet structure and the known β-TCP crystal model. In contrast, a model featuring partial H for Ca su...

THE INFLUENCE OF CALCIUM INFILTRATION ON THE SINTERING BEHAVIOR AND DISSOLUTION OF BETA-TRICALCIUM PHOSPHATE by

Polymerized-complex method for preparation of supported bimetallic alloy and monometallic nanoparticles.

Herein, we report a novel polymerized-complex method for the preparation of Ni-Pd, Ni-Pt, and Cu-Pt alloys and Pt, Pd, Ag, Ni, and Cu nanoparticles. The grain sizes and crystalline phases of these nanoparticles can be controlled. These nanoparticles are obtained via the formation of a polymerized complex and release of reducing gases during N2-protected calcination.
