The preparation of amorphous nanopowders by flame synthesis opens access to common soda-lime, metal-doped glasses or bioglasses in the range of 20-80 nm and offers an alternative to conventional wet-phase preparation, solid state reactions or melting.

in this investigation, a facile and green sonochemical route has been developed for the synthesis of 2-ketomethylquinolines by using 2-methylquinolines and several acyl chlorides in the presence of nanocrystalline mgal2o4 as an efficient heterogeneous catalyst. the combination of nanocatalyst and ultrasonic process afforded corresponding ketomethyl quinolines in shorter reaction durations, and ...

Synthesis of lipoamino acids via ester–amide exchange under prebiotically plausible wet-dry cycling conditions that results in vesicles at acidic pH.

(diacetoxyiodo)benzene has been used as an efficient catalyst for an improved and rapid one-pot synthesis of biscoumarin derivatives in excellent yield under reflux condition using water as a environmentally benign reaction medium. this aqua mediated knoevenagel condensation of various aromatic and hetero-aromatic aldehydes with 4-hydroxycoumarin using catalytic amount of (diacetoxyiodo)benzene...

a general synthetic route to the synthesis of imidazoles has been developed using nano sbcl5/sio2 under solvent-free conditions. the multi-component reactions of aldehydes, benzil and ammonium acetate were carried out to afford some trisubstituted imidazole derivatives. this method provides several advantages like simple work-up, environmentally benign, and shorter reaction times along with hig...

This thesis reports a Genetic Algorithm approach for the mask-layout and process flow synthesis problem. For a given desired target shape, an optimal mask-layout and process flow can be automatically generated using the Genetic Algorithm synthesis approach. The Genetic Algorithm manipulates and evolves a population of candidate solutions (mask-layouts and process parameters) by utilizing a proc...

An enzymatic method has been developed for the measurement of malonyl-CoA in perchioric acid extracts of liver. With this method the relative activities of acetyl-CoA carboxylase and fatty acid synthetase have been studied in vivo by comparing the diet-induced changes in malonyl-CoA concentrations with rates of 3Hz0 incorporation into fatty acids. Malonyl-CoA concentrations were low in the fat-...
