A class of heterogeneous catalysts based on commercial bentonite from natural origin, containing at least 80 wt% of montmorillonite clay, was designed to transform selectively and under mild conditions toxic organosulfur and organophosphorus chemical warfare agents into non-noxious products with a reduced impact on health and environment. The bentonite from the natural origin was modified by in...

the series of mono-metallic and bi-metallic catalysts have been prepared by impregnatingwith solutions containing compound of h2ptc15,nbc15 and lml hc1 (0.1 mol). the activityand selectivity of the catalysts have been determined under conditions at 450-500°c, 15-30atm. molar ratio h2/c7h16=5 and vvh=1.5/h for converting n-heptane. under theseexperimental conditions it has been established that ...

The use of microbial catalysts in the biodegradation of organic compounds has advanced significantly during the past three decades. It has been found that large numbers of microbes co-exist in almost all natural environments, particularly in soils. Many natural and synthetic organic chemicals are readily biodegradable in natural environment. Biodegradation of materials involve initial proximity...

Selective hydroxylation of C H bonds in organic compounds provides an efficient means to access valuable drug metabolites, natural product derivatives, and other fine chemicals. While chemical methods to accomplish this transformation have improved, these generally require the presence of directing groups or electronic properties inherent to certain substrate classes for the desired transformat...

During a recent investigation of the persistence of substrate ambiguity in contemporary enzymes, we identified three distinct ambiguous sugar kinases embedded within the modern Escherichia coli genome [Miller, B. G., and Raines, R. T. (2004) Biochemistry 43, 6387-6392]. These catalysts are the YajF, YcfX, and NanK polypeptides, all of which possess rudimentary glucokinase activities. Here, we r...

There is a world-wide demand for clean, reliable and affordable energy. New technologies are needed to produce more oil and natural gas from ‘stranded’ locations. This work is based on gas to liquid (GTL) conversion of natural gas through Fischer-Tropsch (FT) synthesis. Fe & Co based catalysts of varying compositions were prepared in the laboratory and its performance was checked for the FT rea...
