A green low-cost and reproducible yeast mediated synthesis of silver nanoparticles is reported. The synthesis is performed at room temperature. X-ray and transmission electron microscopy analyses are performed to ascertain the formation of Ag nanoparticles. Nanoparticles almost spherical in shape having a size of 6-20 nm are found.

In this study, a novel method called “atmospheric pressure solution evaporation (APSE)” wasdeveloped for growing of Zinc Oxide (ZnO) nanostructures on Al2O3 surface. Zinc acetate dihydrate,Polyvinyl Pyrrolidone, and deionized water were used as precursor, capping, and solvent, respectively.The growth of ZnO nanostructures from evaporated solution was performed at three temperatures of300, 400, ...

Recent interest in low and negative thermal expansion materials has led to significant research on compounds that exhibit this property, much of which has targeted the A₂M₃O12 family (A = trivalent cation, M = Mo, W). The expansion and phase transition behavior in this family can be tuned through the choice of the metals incorporated into the structure. An undesired phase transition to a monocl...
