Nanohydroxyapatite (nanoHAP) is widely used in bone regeneration, but there a need to enhance its properties provide stimuli for cell commitment and osteoconduction. This study examines the effect of calcination at 1200 °C on physicochemical biological nanoHAP doped with magnesium (Mg2+), strontium (Sr2+), zinc (Zn2+). A synergistic dual modification was investigated. The materials were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), BET analysis,...
Chitosan is one of the most commonly employed natural polymers for biomedical applications. However, in order to obtain stable chitosan biomaterials with appropriate strength properties, it necessary subject crosslinking or stabilization. Composites based on and bioglass were prepared using lyophilization method. In experimental design, six different methods used stable, porous chitosan/bioglass biocomposite materials. This study compared crosslinking/stabilization composites ethanol,...
ABSTRACT Poly(ε‐caprolactone) (PCL)‐hydroxyapatite (HAP) biocomposites were produced by thermal processing to test the impact of HAP addition on physicochemical and biological properties PCL. Two different HAPs: zinc‐modified unmodified, added polymer matrix enhance their biocompatibility, surface properties, antimicrobial activity. The overall assessed mechanical analysis, while structure morphology electron microscopy infrared spectroscopy. A short‐term degradation process composites in...
Hydroxyapatite (HAp) of different morphologies was prepared by the direct decomposition calcium lactate pentahydrate chelates using dipotassium hydrogen phosphate under hydrothermal conditions. The proposed technique allows for precise control HAp crystals morphology and product purity, which are necessary biomedical applications. synthesis parameters such as reagent concentrations, pH, reaction time, temperature, pressure, stirring rate were optimized in order to produce phosphates (CaPs)...
Abstract The rheological properties of shear thickening fluids based on silica powder particles size in range 0.10 – 2.80 μm and poly(propylene glycol) 425, 1000, 2000 g/mol molar mass were investigated. effect particle the length polymeric chain was considered. objective this study to understand basic trends physicochemical used materials onset maximum dilatant effect. Outcome research suggested that an increase caused a decrease shift towards higher rate values. Application carrier fluid...
We show that the switchable mirror material ${\mathrm{YH}}_{x}$ can be used both as an indicator to monitor and agent control hydrogen diffusion in thin films. The applicability of optical-indicator technique is demonstrated for ${\mathrm{VH}}_{x}$ coefficient typically ${10}^{\ensuremath{-}5}{\mathrm{cm}}^{2}/\mathrm{s}$ at concentrations around 0.7 H/V temperatures between 373 473 K. Deposition a layer Y on V makes it also possible tune effective mobility via V/Y thickness ratio. This...
Composites based on polylactide (PLA) and hydroxyapatite (HA) were prepared using a thermally induced phase separation method. In the experimental design, PLA with low weight-average molar mass (Mw) high Mw tested inclusion of HA synthesized as whiskers or hexagonal rods. addition, structure was doped Zn, whereas rods mixed Sr salt. The composites sterilized then incubated in phosphate-buffered saline for 12 weeks at 37 °C, followed by characterization pore size distribution, molecular...
The development of innovative biomaterials with improved integration bone tissue and stimulating regeneration processes is necessary. Here, we evaluate the usefulness bioactive glasses from SiO2-P2O5-CaO system enriched 2 wt.% SrO or ZnO in manufacturing chitosan-based scaffolds. Bioglasses produced using sol-gel method were subjected to thermal treatment different regimes. Chitosan/bioglass composites a weight ratio. evaluated via TG-DTA, FTIR, SEM-EDS before after incubation simulated body...
