Harnessing Carbon‐Containing Materials for Next‐Generation High‐Temperature Electromagnetic Wave Absorbers

open access: yesCarbon Energy, EarlyView.
Traditional carbon materials show limited high‐temperature oxidation resistance, which becomes pronounced above 673 K and significantly restricts their practical applicability. To address this challenge, enhancing polarization loss and leveraging its negative temperature dependence to offset the temperature‐induced increase in conductance loss are ...

Nonthermal Food Processing Technologies: A Comprehensive Review

open access: yesFuture Postharvest and Food, EarlyView.
The graphical abstract illustrates the shift from traditional thermal food preservation methods to advanced nonthermal technologies. Traditional methods, represented by heating, often compromise the nutritional and sensory quality of foods. In contrast, nonthermal approaches such as high‐pressure processing (HPP), pulsed electric field (PEF ...
