The laser-induced effects on dielectric properties of chalcogenide glass(Ch Gs) have been present in a glassy system of Se–Te–Sn–Cd for possible applications in optics and optoelectronics such as light-controlled capacitance-based touch displays. The temperature/frequency dependence of dielectric relaxation before and after laser exposure was investigated by using laser sources of different wavelengths(405 nm, 532 nm, 690 nm, and 785 nm). The result showed the presence of laser-induced residual effects on dielectric properties(dielectric constant/loss and a.c. conductivity) after the exposure of continuous-wave laser sources of chosen *** analysis indicates that the modification in the meta-stable state due to self-organization is the feasible mechanism of observed persistent light-sensing effects.

OBJECTIVE: To investigate the effect of Sharbat-e-Deenar(SD) on acetaminophen(APAP)-induced hepatotoxicity in rat ***: Albino rats were treated with SD at the doses of 1, 2 and 4 mL/kg, p.o. against hepatotoxicity after APAP(2 g/kg, p.o. once only) *** blood, tissue biochemical parameters and histopathological observation were performed. The RESULTS: APAP exposure in rats significantly increased the level of biochemical parameters such as aspartate aminotransaminase, alanine aminotransaminase, lactate dehydrogenase, serum alkaline phosphatase, bilirubin, urea and creatinine into blood circulation which were reversed towards normal by SD therapy at all doses. The tissue biochemical parameters such as lipid peroxidation, reduced glutathione, adenosine tri-phosphatase and glucose-6-phosphatase were significantly restored after SD treatment against hepatotoxity. Histological analysis confirmed that SD-treated rats significantly alleviated of liver damage and reduced lesions caused by APAP intoxication. The biochemical changes are in good correlation with the histopathological ***: On the basis of these results, it can be concluded that SD exerts hepatoprotective activity against APAP-induced liver injury.

Titania （TiO2） and barium titanate （BaTiO3） were synthesized using three different dicarboxylates, which included oxalate, malate and tartarate. These powders were characterized by X-ray powder diffraction, scanning electron micrographs, BET specific surface area and particle size distribution. Their properties depended to a great extent on the nature of the precursor. The titania and barium titanate powders obtained from the tartarate precursor were found to be good for slip casting. Slips of these oxides with different solids contents were prepared at different pH values using both distilled water and ethanol as the dispersing agent and also with and without deflocculant. The theological behaviors of the suspensions were then determined, and the slip, green and sedimentation bulk densities were measured. The minimum viscosities were observed at pH 8.2 for the TiO2-water and pH 10.2 for the BaTiO3-water system.
