ABSTRACT Ru(II)BT have been synthesized by the reaction between substituted bromobenzal thiosemicarbazones and precursors of ruthenium metal complexes, [RuHCl(CO)(EPh3)3] (where E = P/As). The Ru(II)BT was characterized analytical spectroscopic techniques. It confirms coordination thiosemicarbazone ligands suggest octahedral geometry complexes. is comprised a centre with bidentate ligands. s...

Cyclic polymers have long been reported in the literature, but their development has often stunted by synthetic difficulties such as presence of linear contaminants. Research into synthesis these made great progress past decade, and this review covers synthesis, properties, applications cyclic polymers, with an emphasis on bio-based aliphatic polyesters. Synthetic routes to synthesized from bio...

At the beginning of the20th century classical biotechnology and chemical synthesis were for many purposes alternative technologies. Spite of the importance of classical bio-technology (which mainly drew on the application of enzymatic processes and microbiology for the production of good and services) at that time specially in Germany, the German drug producers made use of the organic chemical ...

Abstract A simplified and scalable one‐pot process for the anaerobic production of succinic acid using a metabolically engineered Corynebacterium glutamicum strain is demonstrated. With targeted bioprocess optimization, titer 78 g L −1 yield 1.41 mol SA GLC were achieved. Succinic was recovered from neutral fermentation broth by electrochemically induced crystallization applied polybutylene bio...

We report here a "green" approach for the synthesis of gold nanoparticles (GNPs) in which the Mentha piperita extract was applied for the bioreduction of chloroauric acid and the stabilization of the formed nanostructures. The obtained GNPs were characterized by UV-Vis absorption spectroscopy and transmission electron microscopy (TEM). The reduction of gold ions with the plant extract leads to ...

   The use of plant extracts for nanoparticles synthesis are green, economical and cost effective approach.  The present study reports the bio-synthesis of gold nanoparticles (Au NPs) using leaf extract of Terminalia arjuna. After exposing the gold ions to aqueous solution of leaf extract, rapid reduction of gold ions into gold nanoparticles is observed within few minutes. The characterizat...
