the present study concentrates on the synthesis of au nanoparticles (aunps) using aqueous solution of polyvinylpyrrolidone (pvp) and tetrachloroaurate by different methods as thermal, sonochemical and electrochemical reduction. the pvp has been used as a reducing agent and acts as a stabilizer for au nano particles that obtained as principal product. in all synthesis procedures, the active radi...

In this study, yttrium aluminum garnet (YAG) was prepared using a facile electrochemical technique. Four samples were synthesized in 0, 20, 40 and 60°C by electrochemical pulse deposition and were then calcined at 1200°C. The effect of synthesis temperature on morphology and structure of YAG was studied using X-ray diffraction, Fourier transform infrared spectroscopy and scanning electron micro...

The total synthesis of TMG-chitotriomycin using an automated electrochemical synthesizer for the assembly of carbohydrate building blocks is demonstrated. We have successfully prepared a precursor of TMG-chitotriomycin, which is a structurally-pure tetrasaccharide with typical protecting groups, through the methodology of automated electrochemical solution-phase synthesis developed by us. The s...
