Solar energy is only renewable energy source that does not depend on earth's resources. Current industrial manufacturing of solar cells use manufacturing steps that have many sustainable issues. So it becomes very important to promote technologies that are more sustainable than current state of the art. This paper will look into prospects of microwave heating for silicon solar cell fabrication ...

background and aims. although microwave irradiation has been used for disinfection of dental stone casts, there are concerns regarding mechanical damage to casts during the process. the aim of this study was to evaluate the effect of microwave irradiation on the compressive strength (cs) and diametral tensile strength (dts) of stone casts. materials and methods. in this in vitro study, 80 cylin...

Microwave coagulation therapy (MCT) has been employed mainly for treatment of small size tumors. In the treatment, thin microwave antenna is inserted into the tumor and microwave energy heats up the tumor up to at least 60 degrees C for generation of enough coagulated volume including the target tumor. During the microwave radiation, reflection coefficient of treatment antenna changes significa...

In this project various types of carbonyl compounds were efficiently converted to their corresponding 1,3-oxathiolanes  with 2-mercaptoethanol in the presence of catalytic amount of Al-MCM-41 with microwave energy. The catalyst can be reused several times without loss of its catalytic activity. Very short reaction times, reusability of the catalyst, and easy workup are noteworthy advantages of ...

a phosgene-free synthesis of symmetrical n,n'-disubstituted urea by the reaction of aromatic and aliphatic primary amines and urea promoted by  microwave irradiation in the presence of a suitable energy-transfer solvent such as n-n-dimethylacetamide is described.

A new simple procedure for microwave-assisted organic synthesis under continuous flow processing has been developed for use in a monomodal microwave synthesizer with direct temperature control using the instrument's in-built IR sensor. This design makes optimum use of the standing wave cavity to improve the energy efficiency of microwave-assisted flow reactions.

Microwave heating was employed for preparation of the standard gas of volatile organic compounds (VOCs) and semivolatile organic compounds (semi-VOCs) by using a 1000 W commercial domestic microwave oven and 1 L gas-sampling bulbs. The VOCs investigated were benzene, chloroform, 1,3-dichlorobenzene, tetrachloroethylene, toluene, and 1,1,2-trichloroethane, and the semi-VOCs used were the polychl...

Metal Chalcogenides (MCs) have emerged as an extremely important class of nanomaterials with applications ranging from lubrication to energy storage devices. Here we report our discovery of a universal, ultrafast (60 seconds), energy-efficient, and facile technique of synthesizing MC nanoparticles and nanostructures, using microwave-assisted heating. A suitable combination of chemicals was sele...
