The green synthesis of nanoparticles is one step toward the sustainable development. Green tea extract was used as a source for synthesizing bimetallic Au-Ag Nanoparticles. These bimetallic nanoparticles were characterized by UV spectroscopy and TEM examination, which revealed the particles have core and shell structures. Bimetallic NPs have shown promising antibacterial, antifungal  and antioxidant activity.

The possibility of determination the electrochemical behavior of thionalide and thiourea on a platinum disk microanode is shown. The influence of background electrolytes and buffer mixtures on the conditions, course and results was studied. Based on these data methods for the amperometric determination of Pd(II) and Ag(I) using solutions of thioureas(TU) and thionalide (TNL) on a platinum rotating anode by its oxidation current, with a clear titration curve characterized by a clear endpoint were developed.
