Many minerals are effective absorbers of microwave energy, whereas in general gangue materials are not. This suggests applying microwave heating to mineral processing to effect selective heating of minerai phases. Many mineral processing applications have been tested only on a laboratory scale; the engineering realities of large-scale operations have largely been overlooked. Of particular conce...

Due to the recent development of wearable electronic textiles and smart textiles, the conductive fabrics and electrically heated garments have been extensively studied and applied in many fields. In this work an electric heating fabric was fabricated by sewing silver coated nylon yarn over the polyester fabric. In order to minimize the power consumption, instead of heating whole garment surface...

We use hydrodynamical simulations to assess the impact of radiative cooling and ‘pre-heating’ on predictions for the Sunyaev–Zel’dovich (SZ) effect. We find that cooling significantly reduces both the mean SZ signal and its angular power spectrum. Pre-heating can give a higher mean distortion, while leaving the angular power spectrum below that found in a simulation without heating or cooling. ...

A versatile system is described for locally heating a number of mouse tumours simultaneously using RF capacitive coupling. The system is designed around a single RF power amplifier supplying a number of heating jigs via an efficient isolated power splitter. It is primarily intended for use at 13.56 and 27.12 MHz, but can operate from 2-30 MHz and could be modified for use at other frequencies. ...

This paper introduces a new method to control resonance frequency and output power of induction heating coil. Induction heating coil can be controlled by single phase sinusoidal pulse width modulation (SPWM) inverter .All electrical requirements beside magnetic permeability and resistivity variation for modeling induction heating coil have been considered to make simulations practical .Control ...

We have performed in situ quasielastic neutron scattering (QENS) measurements on zeolite-guest systems under microwave irradiation, for comparison with corresponding simulations. Both experiment and simulation reveal selective heating of methanol in silicalite, but little to no heating of benzene in silicalite. Effective translational and rotational temperatures extracted from QENS data under m...

amodified technique is designed to prepare aligned nanofibers to challenge the existing limitations in collecting methods of nanofibers such as, thickness of collected layer, alignment and productivity of nanofibers. collecting and simultaneously heating of the aligned nanofibers were carried out by using a rotating drum fixed on top of syringe needles and applying hot air flow. this electrospi...

Results of ICRF heating experiments in Alcator C-Mod during the November 1994 June 1995 campaign are summarized. Efficient heating of high density ( , ; 3 x 1020 m-3 ) plasmas was demonstrated with high power densities (up to 5 MW/m 3 volume averaged, 0.6 MW/m 2 surface averaged). These experiments were carried out with RF powers up to 3.5 MW at 80 MHz, at magnetic fields up to 8 T and plasma c...
