TL;DR: In this paper, a review of the synthesis of silica aerogels by the sol-gel method, as well as drying techniques and applications in current industrial development and scientific research is presented.

TL;DR: Total antioxidant capacity of plasma was significantly increased after taking green tea in amounts of 300 and 450 ml, and a positive increment according to green tea dosage was also observed.

TL;DR: In this article, zinc oxide nanoparticles (ZnO NPs) were prepared using S. ebulus leaf extract, and their physicochemical properties were investigated using X-ray diffraction (XRD) results revealed that the prepared NPs are highly crystalline, having a wurtzite crystal structure.

TL;DR: In this article, a new layered chalcogenide semiconductor, Bi2MnTe4, was discovered and its crystal structure was determined by powder X-ray diffraction and Rietveld refinement.

TL;DR: In this paper, the chemical composition, states of functional groups and microstructure of the aluminum oxide films were investigated using FTIR, XPS, AES and TEM, and it was found that carbon and hydrogen atoms are incorporated less at higher deposition temperatures and are almost completely removed as CO2 and H2O, by post-deposition heat treatment at 800 °C in an oxygen environment.
