A simple and efficient target preparation method is developed combining spin coating solution combustion synthesis. Multiple smooth uniform UO 2 targets have been prepared using this on a variety of backings (aluminium, carbon, silicon) used in nuclear physics experiments. The thicknesses the can be precisely tuned by changing number coatings within range ~50-1000 µm/cm . These are highly (<...

Glycerol mono-oleate (GMO) was produced by direct esterification reaction with amberlyst 16 resin catalysts with the efficiency of 86% and was used as a surfactant for synthesis of CoFe2O4 nano-particles by surfactant-assisted microwave method. Fourier transform infrared spectroscopy (FT-IR), X-Ray diffraction (XRD) and scanning electron microscopy (SEM) were used to consider the structural and...

This paper outlines the synthesis of CuFe2O4 nanoparticles and their catalytic applications. CuFe2O4 nanoparticles were synthesized via microwave-assisted co-precipitation method. The obtained nanoparticles characterized through Fourier transform infrared spectroscopy, X-ray diffraction, and scanning electron microscopy. Vibrating sample magnetometer shows nanoparticles exhibit ferromagnetic be...

We report on a facile and rapid microwave-assisted method for preparing a sodium-cadmium metal-organic framework (having coordinatively unsaturated sodium ions) that considerably shortens the conventional synthesis time from 5 days to 1 hour. The obtained (Na,Cd)-MOF showed an excellent volumetric CO2 adsorption capacity (5.2 mmol cm(-3) at 298 K and 1 bar) and better CO2 adsorption properties ...

This paper focuses on the synthesis and the photoluminescent properties of Ca3 xAl2O6:xEu 3þ (0rxr0.1) nanophosphors prepared by microwave-assisted combustion method without any further heat treatment. X-ray diffraction, scanning electron microscopy and photoluminescence spectroscopy were used to characterize the produced samples. Nanosized particles smaller than 120 nmwere obtained as confirme...

UNLABELLED BACKGROUND Coumarin derivatives exhibit a wide range of biological properties including promising antioxidant activity. Furthermore, microwave-assisted organic synthesis has delivered rapid routes to N- and O-containing heterocycles, including coumarins and thiazoles. Combining these features, the use of microwave-assisted processes will provide rapid access to a targeted coumarin...
