silica refractory bricks are used especially in the metallurgical industries, due to desirable properties suchas high melting point, rigidity, and high temperatures strength. in this research, different amount of sicwere added to silica refractory containing different binders such as borax, boric acid, calcium nitride,sodium tri poly phosphate, sodium hexa meta phosphate (shmp) and lime. physic...

The good cladding of a large-sized Nd-doped phosphate glass slab as laser amplifier requires not only the amplified spontaneous emission and parasitic oscillation to be fully absorbed, hold up small signal gain coefficient Nd ions, but also absorbed heat energy appropriately dissipated extend uniform temperature field for larger beam aperture edge-cladded Nd–glass slab. In present work, numeric...

AbstractBioactive glass with frame of SiO2-CaO-P2O5-ZnO-MgO-SrO was prepared using quick alkali mediated sol-gel process. The functional group analysis, morphology, composition and phase analysis of this glass were done by using FTIR, FESEM, EDX and XRD respectively. The bioactive nature of the sample was analyzed by immersion in Phosphate Buffer Saline (PBS) for a period of 7 days and characte...

We have investigated the use of tightly focused, temporally shaped femtosecond (fs)-laser pulses for producing nanostructures in two dielectric materials (sapphire and phosphate glass) with different characteristics in their response to pulsed laser radiation. For this purpose, laser pulses shaped by third-order dispersion (TOD) were used to generate temporally asymmetric excitation pulses, lea...

A conducting lithium aluminum germanium phosphate (LAGP) glass-ceramic with a formula of Li1.5Al0.5Ge1.5(PO4)3 was synthesized by melt-quenching method and subsequent crystallization at 850 °C for 8 h. The prepared glass-ceramic was characterized using differential scanning calorimetry (DSC), X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), and AC impedance techniqu...

introduction: glass-ionomer cements (gics) are one of the most important dental restorative biomaterials. the aim of this study was to synthesize glass-ionomer‒silk fiber composite and evaluate the effect of adding natural degummed silk fiber on the bioactivity and the ability to release fluoride by glass-ionomer cement. materials and methods: in this study, commercial fuji ii glass-ionomer cem...

in order to evaluate the effect of balanced application of chemical phosphorus fertilizer and seed inoculation with phosphate solubilizing bacterium and arbuscular mycorrhizal fungus and on the yield and yield components of maize (zea mays l.) under normal and limited irrigation conditions, a split-split plots arrangement based on randomized complete block design with three replications was con...

Eight novel silicate, phosphate and borate glass compositions (coded as NCLx, where x = 1 to 8), containing different oxides (i.e. MgO, MnO2, Al2O3, CaF2, Fe2O3, ZnO, CuO, Cr2O3) were designed and evaluated alongside apatite-wollastonite (used as comparison material), as potential biomaterials for bone tissue repair and regeneration. Glass frits of all the formulations were processed to have pa...

This work focuses on the synthesis and characterization of a novel bioresorbable glass ceramic phosphate-based material (GC-ICEL). More specifically, its solubility in different aqueous media (water, Tris-HCl and acellular simulated body fluid) and the response of human stromal cells cultured on it were investigated. X-ray diffraction analysis showed the presence of two crystalline phases ident...
