We describe a microfluidic device with an integrated microwave heater specifically designed to dielectrically heat non-aqueous droplets using time-varying electrical fields with the frequency range between 700 and 900 MHz. The precise control of frequency, power, temperature and duration of the applied field opens up new vistas for experiments not attainable by conventional microwave heating. W...

Mesoporous silica materials (MSMs) of the MCM-41 type were rapidly synthesized by microwave heating using silica fume as silica source and evaluated as adsorbents for the removal of Cu2+, Pb2+, and Cd2+ from aqueous solutions. The effects of microwave heating times on the pore structure of the resulting MSMs were investigated as well as the effects of different acids which were employed to adju...

Piyasena, P. and Dussault, C. 2003. Continuous radio-frequency heating of a model viscous solution: Influence of active current, flow rate, and salt content on temperature rise. Canadian Biosystems Engineering/Le génie des biosystèmes au Canada 45: 3.273.34. Radio frequency can induce molecular friction in food products resulting in an internal heating effect; therefore, better heating of sensi...

1. The transforming power of red blood cells for atoxyl is apparently uninfluenced by a preliminary heating of the blood for 30 minutes at 50 degrees C., but a temperature of 55 degrees C. acting for 30 minutes destroys this property of blood almost completely. 2. When the heating was for 60 minutes, 54 degrees C. and higher temperatures apparently destroyed all the transforming power. 3. After...

B4C–Al2O3 composite powder was produced by aluminothermic reduction in Al/B2O3/C system. In this research, microwave heating technique was used to synthesize desired composite. The ball milling of powder mixtures was performed in order to study the effect of mechanical activation on the synthesis process. The synthesis mechanism in this system was investigated by examining the correspondi...
