Out-of-oven rapid synthesis of entropy stabilized oxides using radio frequency heating

open access: yesJournal of Materials Research and Technology, 2023
Entropy stabilized oxides (ESOs) are a new class of stable hybrids and single phase metal oxides made from multiple ions with material properties somewhere between the constituent oxides, or occasionally entirely new properties. One of the limitations of

On the feasibility of wireless radio frequency ablation using nanowire antennas

open access: yesAPL Materials, 2021
Radio frequency ablation (RFA) is a proven technique for eliminating cancerous or dysfunctional tissues in the body. However, the delivery of RFA electrodes to deep tissues causes damage to overlying healthy tissues, while a minimally invasive RFA ...

Single phase matrix converter for radio frequency induction heating [PDF]

open access: yes, 2006
Conventional converters for radio frequency induction heating usually follow an AC-DC-AC structure, which can exhibit non-unity power factor and introduce large harmonic currents into the utility supply.

Microwave and Radio Frequency Heating [PDF]

open access: yesFood Science and Technology International, 2008
This paper brings to perspective issues related to research initiatives for the application of microwave (MW) and radiofrequency (RF) applications in foods. Both MW (300 MHz and 300 GHz) and RF waves (3 kHz — 300 MHz) are part of the electromagnetic spectrum that result in heating of dielectric materials by induced molecular vibration as a result of ...

Direct measurement of axial momentum imparted by an electrothermal radiofrequency plasma micro-thruster

open access: yesFrontiers in Physics, 2016
Gas flow heating using radio frequency plasmas offers the possibility of depositing power in the centre of the flow rather than on the outside, as is the case with electro-thermal systems where thermal wall losses lower efficiency.
