Comparative Study on Remineralizing Ability of Casein Phosphopeptide Amorphous Calcium Phosphate and β-Tricalcium Phosphate on ...

Calcium deficient nanohydroxyapatite (nanoHap) powders were synthesized by co-precipitation of calcium α-D-heptagluconate hydrate and diammonium hydrogen phosphate solutions. TEM and HRTEM images of powders after the drying of products showed that the reactant concentration affected the sizes and morphology of particles. Small changes were found in phase composition of nanoHap powders synthesiz...

Starting powders of silicon-substituted beta-tricalcium phosphate (β-TCP/Si) were prepared by the polymerized complex method. Silicon ions blended up to 3.0 mol% total P content. The raw product powder was calcined at 1000 °C, formed into pellets, and sintered 1120 °C for 24 h. resultant bodies showed that a single phase β-type tricalcium (β-TCP) can be obtained with silicon addition 0-2.0 subs...

Objective- The aim of this study was to evaluate possible beneficial effect of tricalcium phosphate/collagen (TCP/collagene) nanocomposite scaffold on bone healing in rabbits using biochemical assessmentsDesign- Experimental studyAnimals- Twelve healthy male white New Zealand rabbitsProcedures- The rabbits wer...

Reproducible time-of-flight cluster static secondary ion mass spectra (ToF-SSIMS) were obtained for various standard calcium phosphate (CP) powders, which allowed for phase identification. X-ray diffraction was not able to detect signals from microscopic amounts of CP (∼15 mmol m(-)(2)). The phases studied were α-tricalcium phosphate [α-Ca(3)(PO(4))(2)], β-tricalcium phosphate [β-Ca(3)(PO(4))(2...

in order to study the effect of synorhizobium meliloti on growth and nutrients uptake of sesame, a greenhouse test was carried out. the first isolates investigated in iaa and siderophore producing and their ability in solubilizing inorganic phosphates. the results showed that all of isolates were able to produce auxin with different among. the maximum amount of iaa production was 59.5 g ml-1 th...

The bulk of the world's phosphate reserves is located in sedimentary horizons that contain appreciable amounts of carbonate. During beneficiation of phosphate rocks, huge amounts of oversize phosphate rocks are rejected from crushers. This reject also mostly contains low tricalcium phosphate and high carbonate content. In this study, experiments have been carried out to reduce/eliminate car...
