Titanium (Ti4+ ) containing materials have been widely used in medical applications due to its associated bioactivity vivo. This study investigates the replacement of Si4+ with Ti4+ within system SiO2 -Na2 O-CaO-P2 O5 determine influence on glass structure. strategy was conducted order control solubility further improve cellular response. incorporation found little transition temperature (Tg = 520 ± 8°C) and magic angle spinning-nuclear magnetic resonance (MAS-NMR) shifts (-80 ppm) up...
The chemical strengthening of Li2O•2SiO2 transparent glass-ceramics was investigated. fracture strength glass and increased first then decreased, the crack formation peeling ion exchanged layer were observed for both Li+↔Na+ Li+↔K+ exchange. This suggests that submicroscopic generates perpendicular to surface when peels off from surface. volume change by exchange is very large, over 10%, this large causes peeing despite in which compressive stress arise. In early stage exchange, arisen...
Hydroxyapatite (Ca10(PO4)6(OH)2) is widely investigated as an implantable material for hard tissue restoration due to its osteoconductive properties. However, hydroxyapatite in bulk form limited mechanical properties are insufficient load-bearing orthopedic applications. Attempts have been made improve the of hydroxyapatite, by incorporating ceramic fillers, but resultant composite materials require high sintering temperatures facilitate densification, leading decomposition into tricalcium...

Effect of strontium (Sr) substitution on bioactivity hydroxyapatite (HA) was investigated. The Sr <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2+</sup> for Ca in the HA lattice increases biodegradability Sr-substituted (Sr-HA) and accelerates formation apatite crystals Sr-HA surface. Moreover, dissolution products from samples are not cyto-toxic.
Structure and several properties of AgNO3 As2O3 doped polymer composites have been investigated, including their antibacterial activity against E. coli, S. aureus, C. albicans epidermidis. New silver or arsenic characterized by an X-ray diffraction (XRD), a scanning electron microscopy combined with energy dispersive spectroscopy (SEM/EDS) ion release studies. The evaluation each the composite samples was conducted using aureus in liquid broth culture, 10, 20 30 % extract added to bacterial...
Sr-HA/Glass composites were produced. Phase composition of was evaluated. Their physical and mechanical properties determined. Sintered mainly consisted Sr-HA/β-TCP, or β-TCP/Ca <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> ZnSi O xmlns:xlink="http://www.w3.org/1999/xlink">7</sub> . The had porosity up to 4 times those undoped Sr-HA. Compared Sr-HA, the lower biaxial flexural strength hardness. Weibull modulus for ranged from 2.77 18.74.

The caused decomposition HA to tricalcium phosphate, inhibiting densification in HA/glass composites. However, depending concentration, some can act sintering aid enhancing
Giant leucaena wood was utilized to prepare heterogeneous catalysts through a fast pyrolysis method and chemical activation for transesterification. The obtained were investigated using SEM, CHNS/O analyzer, XRF XRD. influence of the concentration KOH (3-9 M), catalyst amount (0.25-2.0 g), methanol oil ratio (4:1-10:1), reaction time (30-75 min) on FAME yield also studied transesterification carried out at 60ºC under 750 rpm stirring speed. experiment results demonstrate that required...
