Reducing particle size of persistent luminescent SrAl_2O_4:Eu^2+,Dy^3+via microwave-assisted, reverse micelle synthesis

Effect of molar ratio and calcination temperature on particle size of CeO2/-Al2O3 nanocomposites prepared via reverse micelle process

A porous composite of cerium oxide and gama aluminum oxide pigments were prepared via sol-gel processing controlled within reverse micelles of nonionic surfactant Triton X-114 in cyclohexane. The precursor in heated at several calcinations temperature between 823 to 1123K. This process includes three steps. In the first step of preparation the ceria sol was prepared. In the second step, cyclohe...

Microwave-assisted synthesis of molybdenum oxide nanoparticles

This paper focused on a simple approach for synthesis of molybdenum oxide (MoO3) nanoparticles and reports a facile route for synthesis of such nanoparticles, using microwave irradiation as a homogenous and powerful source of heating, using ethylene glycol as the solvent and heating medium. For more investigations, besides microwave heating, the obtained solutions were also treated by conventio...

Microwave Assisted Synthesis of N-Benzylenaminones Catalyzed by Chloroacetic acid

Benzylaminoalkenones and benzylaminoalkenoates 3 were synthesized from reaction of benzylamine with corresponding 1,3-diketones and 1,3-ketoesters in the presence of catalytic amount of chloroacetic acid under microwave radiation. This method offers several advantages including high yield of products, recyclable of the catalyst and easy experimental work-up procedure.

Ammonium chloride catalyzed microwave-assisted synthesis of tetrahydrobenzo[b]pyrans

In the present work, we have developed a mild, efficient, and environmentally benign method for the synthesis of tetrahydrobenzo[b]pyran derivatives via a three-component cyclocondensation of aldehydes, malononitrile and dimedone utilizing ammonium chloride as a simple, easily available and cost effective catalyst under microwave irradiation. This method has several attracting features such as ...
