Barium strontium titanate (BST) or Ba1-xSrxTiO3 with x=0-1 possesses superior dielectric properties, which are widely used in many applications like in communication technology, electronic instrumentations, and various electrical devices. In this paper, the characterization of the particle and crystallite size of Ba1-xSrxTiO3 (x: 0; 0.3; 0.7) is described. A two-step refinement commenced: first by mechanical milling, and then a further refinement under ultrasonic irradiation in a high power sonicator was applied to Ba1-xSrxTiO3 (x: 0; ...

An efficient and rapid method for preparation of Au nanoparticles (Au-NP) has been developed by direct microwave
irradiation of metal precursor and alginate mixed solution in a single step. Here, alginate molecules act as both the
reducing and stabilizing agents of Au-NP. The obtained nanoparticles were characterized by ultraviolet-visible (UVVis)
spectroscopy, particle size analyzer, fourier transform infrared spectroscopy, and transmission electron
microscopy. The nanoparticles have a spherical form and perfectly capped with alginate when using alginate and chloro
auric acid ...
