Zirconia (ZrO2) based dental ceramics have been considered to be advantageous materials with adequate mechanical properties for the manufacturing of medical devices. Due its very high compression strength 2000 MPa, ZrO2 can resist differing environments. During crack propagation on application stress surface ZrO2, a crystalline modification diminishes cracks. In addition, zirconia's biocompatibility has studied in vivo, leading observation no adverse response upon insertion samples into bone...
Abstract The most common denture material used for dentistry is poly-methyl-methacrylate (PMMA). Usually, the polymeric PMMA has numerous biological, mechanical and cost-effective shortcomings. Hence, to resolve such types of drawbacks, attempts have been made investigate fillers like alumina (Al 2 O 3 ), silica (SiO zirconia (ZrO ) etc. For enhancement properties a suitable additive required its orthopedic applications. Herein, main motive this study was synthesize magnesium oxide (MgO)...
Here, we report the scalable synthesis and characterization of low-density, porous, three-dimensional (3D) solids consisting two-dimensional (2D) hexagonal boron nitride (h-BN) sheets. The structures are synthesized using bottom-up, low-temperature (∼300 °C), solid-state reaction melamine boric acid giving rise to porous mechanically stable interconnected h-BN layers. A layered 3D structure forms due formation h-BN, significant improvements in mechanical properties were observed over a range...
3D (three dimensional) architectures synthesised using an easily scalable solid state method which results in interconnected network of porous h-BN sheets with boron trioxide are reported this study.
Abstract Herein, a novel composite 54[BaO.TiO 2 ]-46[K O.SiO ], (BTKS) was synthesized via melt-quenching approach for detection of CO gas. The measurements gas sensing were performed in the range 250–1500 ppm. XRD study reveals polycrystalline nature with major and minor phases witherite (BaCO 3 ), BaTiSi O 9 BaTiO . Further, UV-Visible spectroscopy used revealed semiconducting composite. SEM TEM rod-like morphology along homogenous pores voids within composite, attributed excellent...
The Mycobacterium tuberculosis is the cause of (TB), a dangerous and highly contagious infection that major source morbidity mortality. One to three percent cases have osteoarticular TB, 10% these involve foot ankle involvement. bone in most frequently attacked by TB calcaneus. There are currently relatively few case series studies Report available describe this uncommon phenomenon. aim narrative review find information on calcaneum tuberculosis-An We evaluated medical records some patients...
A series of glasses were prepared by rapid melt quench method in the glass system (65-x)[(Ba0.6Sr0.4)TiO3]-30[2SiO2-B2O3]-5[K2O]-x[La2O3] (x = 0, 1, 2, 5 and 10). X-ray diffraction samples carried to check its amorphousity. Density measured using Archimedes principle. The refractive index these lies between 2.39 2.80. Optical properties studied Infrared (IR) Raman spectroscopic techniques. IR measurements done over a continous spectral range 450 - 4000 cm-1 study their stucture networking...

In this paper zinc stannate (ZnSnO3) nanoparticles was synthesized by a chemical precipitation method. The samples were characterized using X-ray powder diffraction (XRD), Differential scanning calorimetry (DSC) and UV-Visible absorption spectroscopy. Sensing material made as pellet hydraulic press machine under uniform pressure of 616 MPa. Then the annealed at 600。C. Surface morphologies analyzed Scanning electron microscopy (SEM) for different weight ratio XRD pattern indicates that ZnSnO3...
