Abstract Zirconia doped Hydroxyapatite (HAP) nanocrystals [Ca 10 (PO 4 ) 6−x (ZrO 2 x (OH) ]; (0 ≤ 1 step 0.2) were synthesized using simple low cost facile method. The crystalline phases examined by X-ray diffraction (XRD). crystallinity percentage decreased with increasing zirconia content for the as-synthesized samples. existence of as secondary phase on grain boundaries; observed from scanning electron micrographs (FESEM); resulted in negative values microstrain. crystallite size was...
Co-Substituted hydroxyapatite Mg–Ag-HAP/chitosan biocomposites were synthesized successfully using a simple chemical method, and the compressive strength progressed up to 15.2 MPa at<italic>x</italic>= 0.8.
Hydroxyapatite (HAP) and dicalcium phosphate dihydrate (brushite) nanoparticles were prepared by co-precipitation method. The obtained products characterized X-ray powder diffraction (XRD), Fourier transformation infra-red spectroscopy (FTIR) thermo-gravimetric analysis (TGA). Scanning electron microscopy (SEM) transmission microscope (TEM) used to investigate the morphology of powdered samples as well their microstructure, respectively. Brushite in a spherical shape, while hydroxyapatite...
Tailoring of appropriate nanofibrous scaffold for wound healing applications is required strongly to develop people’s health care system. Graphene oxide (GO) nanosheets containing co-substitution Mg/Se-hydroxyapatite (HAP) were involved in ε-polycaprolactone (PCL) be produced scaffolds. The structural properties both powder and scaffolds characterized using XRD, while the morphological behavior was investigated via FESEM. calculated lattice parameters indicated that HAP tends grow c-axis...
Electrospun selenium-containing carbonated hydroxyapatite/polycaprolactone (CHAP/PCL) core/shell nanofibers were synthesized at different contents of Rb+ as a dopant in the ceramic phase. Microstructural, morphological and mechanical properties analyzed function stoichiometric content ions defined by parameter x [RbxCa(10-0.5x)(PO4)5.8(SeO3)0.2(OH)2]/PCL (0 ≤ 0.8). incorporated inside CHAP crystal lattice, where they induced growth preferred c-axis direction. They also internal disordering,...
For wound healing applications, a scaffold of biocompatible/porous networks is crucial to support cell proliferation and spreading. Therefore,ϵ-polycaprolactone (PCL) nanofibrous scaffolds containing co-dopants strontium/selenium in hydroxyapatite (HAP) were modified with different contributions graphene oxide (GO) via the laser ablation technique. The obtained compositions investigated using XRD, TEM FESEM. It was evident that fiber diameters range 0.15-0.30µm 0.35-0.83µm at lowest highest...
