Synthetic multi-substituted hydroxyapatite nano powders containing silicon and or carbonate prepared by a wet chemical method. The process parameters are set up to allow the simultaneous substitution of ions in place phosphorus. structural characterizations determined with aid of; XRF, ICP, XRD FTIR. results show that, ion crystal lattice HA caused change unit cell dimensions affected degree crystallization produced powders. apatite formation abilityy discs from synthesized is immersing SBF...
Atomic substitution or doping of a bioceramic material hydroxyapatite (HA) with specific ions is an appealing approach for improving its biocompatibility and activity, as well imparting antibacterial properties. In this study, selenium- and/or copper-substituted powders were synthesized by aqueous precipitation method using the freeze-drying technique. The molar concentrations constituents calculated based on proposed mechanism whereby selenium (Se4+) partially substitute phosphorus (P5+)...
Limitations with the majority of bone therapeutic treatments include low availability, ethical constraints and biological compatibility. Although a number choice materials have been exploited successfully, there has always scope for improvement as well development next-generation materials. Herein, scaffolds - developed from gelatin, chitosan eggshell membranes were crosslinked using tannic acid, further infused selenium and/or copper substituted hydroxyapatite nanoparticles to generate...
Precursors for the preparation of Si-CHA (silicon and carbonate substituted hydroxyl-apatite) were added in stoichiometric composition amounts either 30 or 50 solid wt. % to a solution gelatin form hybrid nano-composite scaffolds (B(G/Si-CHA)). Temperature was maintained at 40°C pH 8 during reaction. Glutaraldehyde complete cross-linking then washed. Thereafter, glycine product get rid any glutaraldehyde remnants. Both, 50% obtained compared with ones containing same proportions from...
Three formulations of fluorophlogopite and orthoclase (4 : 1, 1 4 molar mixes, based on the stoichiometric composition) were prepared utilising local potash feldspar, as main constituent for dental porcelain containing leucite fluorophlogopite. Powders fritted batches heat treated 2 h at between 950 1050°C, The crystalline phases detected by XRD microstructures characterised SEM with EDAX attachment. A mixture mica was present in formulation 1000°C, sole phase 1050°C. Leucite rich 4....
