Basically provides an alternative methodology to conventional heating, with several advantages like: penetrating radiation, controllable electric field distribution, rapid heating, selective heating of materials, and self-limiting reactions.
Noble metal nanoparticles such as of gold are concentrated only within the tumor cells because of their open texture and vasculature but not in the normal cells which allow the selective heating of the cancer cells upon irradiation with infrared radiation.
This may help to keep the host commodity at relatively low temperature in the selective heating of the insects whose loss factor increased with increasing temperature.
When low-heat-resistant substrates and parts are to be used, it becomes necessary to heat required portions only, using selective heating technologies.
Selective heating has not often been applied to commercial food processing, despite its potential.
The expiration last February of Windmoeller & Hoelscher's patent has opened the door for additional automatic dies that use selective heating of sections of the die lips to control film gauge.
Using the right infrared emission frequency, we can match the material absorption lines to provide selective heating to one type of plastics only," Sticker explained.

The nanoparticles, in turn support the selective heating of the tumour tissue on a cellular level, thereby destroying the tumour cells.
Microwave heating is an attractive method for curing adhesive-bonded joints because of its high productivity, selective heating of the adhesive layer, and improvement of properties of the joint.
One disadvantage of this selective heating is that the outer pins of a connector, for example, will transfer more heat to the board than the inner pins; the colder outer area is larger, so a temperature difference ([DELTA]T) occurs over the pin connector.
