Magnetic nanoparticles MNPs possessing low Curie temperatures TC’s offer the possibility for self-regulated heating of cancer cells, where the TC acts as an upper limit to heating to prevent damage to neighboring healthy tissue. We report the synthesis of monodisperse metastable fcc -phase Fe–Ni MNPs possessing tunable TC’s, whose stoichiometries have been predicted from metastable extensions t...

Dichloro-bis(aminophosphine) complexes of palladium with the general formula of [(P{(NC5H10)3-n(C6H11)n})2Pd(Cl)2] (where n = 0-2), belong to a new family of easy accessible, very cheap, and air stable, but highly active and universally applicable C-C cross-coupling catalysts with an excellent functional group tolerance. Dichloro{bis[1,1',1''-(phosphinetriyl)tripiperidine]}palladium [(P(NC5H10)...

aluminum sulfate nano structures have been prepared by solution combustion synthesis using aluminum nitrate nonahydrate (al(no3)3.9h2o) and ammonium sulfate ((nh4)2so4). the resultant aluminum sulfate nano structures were calcined at different temperatures to study thermal  decomposition of aluminum sulfate. the crystallinity and phase of  the as-synthesized and calcined samples were characteri...

Engineering students in a one-semester organic chemistry laboratory course prepared biodiesel by using either microwave or conventional heating in a discovery-based experiment. The laboratory design was to show improvement in student awareness about the use of microwave heating in organic synthesis in general, and specifically in the preparation of biodiesel. The students were polled before and...

Microwave irradiation has been successfully applied in organic chemistry. Spectacular accelerations, higher yields under milder reaction conditions and higher product purities have all been reported. Indeed, a number of authors have described success in reactions that do not occur by conventional heating and even modifications of selectivity (chemo-, regio- and stereoselectivity). The effect of...

This study proposes an approach to selecting efficient heat sources in the context of long-term expansion planning for urban district heating systems. The includes two stages: synthesis and optimization. During stage, potential source structures are generated using graph grammars. In optimization most effective combination equipment is selected based on minimum construction costs, network pollu...

an attempt was made to investigate the thermal and residual stress distribution in a novel three layer (la 2 zr 2 o 7 / 8ysz/ nicraly) during a real-like heating regime which includes heating, service time and final cooling. for achieving maximum accuracy and consistency in calculation of thermal and mechanical properties of hybrid coating system, all related andrequired properties were introdu...

this paper modeled heating air of a room through examining free convection in a 3d chamber. the chamber had cold and hot sources with tc and th temperatures, respectively. its other walls were adiabatic. this study aimed at predicting effect of temperature difference, displacement of hot and cold sources and their aspect ratio on flow field, temperature and heat transfer rate. to conduct the st...

The global interest on microwave assisted chemistry (MAC) is due to the important benefits for sustainable growth of green chemical industries and environmentally friendly progress society. MAC has been firstly developed using oven-type microwaves (MWs) reactors, which requires difficult expensive industrial scale-up. In 2002, development coaxial dipole antenna allowed a direct application MWs ...

The concept of using a thermoresponsive ionic liquid (IL) with an upper critical solution temperature (UCST) as a draw solute in forward osmosis (FO) was successfully demonstrated here experimentally. A 3.2 M solution of protonated betaine bis(trifluoromethylsulfonyl)imide ([Hbet][Tf2N]) was obtained by heating and maintaining the temperature above 56 °C. This solution successfully drew water f...
