abstract
in the present work, bi2s3 nanostructures have been synthesized with the aid of thioglycollic acid (tga) a solvent, capping agent, and sulfide source in the presence of ultrasonic method. the as-synthesized products were characterized by x-ray diffraction (xrd), energy dispersive x-ray spectroscopy (eds), scanning electron microscope (sem), and photoluminescence (pl) spectroscopy. the band gap of nanoparticles calculated 2.37 ev that shows a blue shift compare bi2s3 bulk. the effects of reaction time and ultrasonic power on the morphology and particle size of product were studied.

Electrochemical synthesis followed by heat-treatment is a facile and easy method for preparation of nanostructured metal oxides. Herein we report nanostructured Mn5O8 prepared through pulse cathodic deposition followed by heat-treatment for the first time. For the preparation of Mn5O8 nanorods, pulse cathodic electrodeposition was first done from 0.005M Mn(NO3)2 at the current density of 5 mA c...

Bismuth sulfide nano-rods and nano-flowers were synthesized via a hydrothermal reaction at a relatively low temperature. Thioglycolic acid is used as sulfur source and capping agent simultaneously. Bi2S3 nanostructures were then added to acrylonitrile-butadiene-styrene (ABS) copolymer. The thermal stability behavior of ABS filled with bismuth sulfide nano-rods were investigated by thermogravime...

Bismuth telluride (Bi2Te3) nano particles were prepared by refluxing method in different conditions such as varying concentration of KOH and reaction timings. X-ray diffraction (XRD) and transmission electron microscopy (TEM) measurements have been performed for structural and phase formation studies. The nanoparticles are showing the same structure of bulk except broadening of peak confirmed b...

TiO2/ZrO2 nanocomposite was obtained by the sonochemical technique. In this method, two separate gels containing zirconium and titanium were prepared and mixed together. The precursor sol of zirconium was prepared from an aqueous solution of ZrCl4. The precursor titanium tetra isopropoxide (TTIP) dissolved in isopropanol. Mixing of Titanium and Zirconium gels was resulted in a yellow TiO2/ZrO2 ...
