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...

Silver nanoparticles were successfully prepared in two different solvents using a microwave heating technique, with various irradiation times. The silver nanoparticles were dispersed in polar liquids (distilled water and ethylene glycol) without any other reducing agent, in the presence of the stabilizer polyvinylpyrrolidone (PVP). The optical properties, thermal properties, and morphology of t...

XC-72 carbon supported Pt catalyst was prepared by using a microwave heated ethylene glycol method and characterized by transmission electron microscopy (TEM) and X-ray diffraction (XRD). For comparison, the same Pt/XC72 catalyst was also prepared by conventional heated ethylene glycol method. TEM image showed that microwave synthesized Pt nanoparticles were uniformly dispersed on the surface o...

In this study, the effect off adding SiO2 nanoparticles on the viscosity of base fluid is investigated experimentally. Base fluids are chosen among common heat transfer fluids such as ethylene glycol, transformer oil and water. In addition different volume percentages of ethylene glycol in water are used as ethylene glycol-water solution. In every base fluid different volume fractions of SiO2 n...

The depolymerization of end-of-life polymers to valued chemicals (waste-to-chemicals) can be a suitable tool for the transformation from linear circular economy. Therefore, poly(ethylene 2,5-furandicarboxylate), discussed as sustainable substitute terephthalate), was studied. In more detail, in presence catalytic amounts zinc(II) acetate 2,5-furandicarboxylate) converted by methanolysis dimethy...

A fast one-pot method has been developed for the direct preparation of 3-aryl-1,2-cyclohexanediones from 2,3-epoxycyclohexanone via a microwave-assisted tandem epoxy ketone isomerization-Heck arylation reaction. The preparative microwave-assisted reactions were performed preferentially in 50% aqueous poly(ethylene glycol) utilizing sodium acetate as the base. Within 5-30 min of directed microwa...

We present a rapid and highly efficient method to form microstructure of poly(ethylene glycol) (PEG)-based acrylates by microwave-induced thermal crosslinking. PEG-based polymeric microstructures such as polymer microarrays and microwells were fabricated on 3-(trimethoxysilyl)propyl methacrylate (TMSPMA)-coated glass slides that were placed on top of a silicon wafer. In comparison to ultraviole...

Sucrose hydrolysis reaction, catalysed by invertase under microwave irradiation was carried out in aqueous, isopropanol + water and polyethylene glycol + water system. The effect of conventional and microwave heating on the rate of hydrolysis was studied under a range of physical exposure conditions. The catalytic activity of invertase in aqueous and organic solvents were measured at different ...
