Circular Economy Pathways for Airport Climate Change Mitigation

Business Strategy and the Environment, EarlyView.
ABSTRACT Airport operators face growing climate‐change pressures; the circular economy offers pathways to reduce impacts and recover resources. We examine how airport operators apply the circular economy in practice. We use an exploratory qualitative multicase design based on practitioner‐generated documents (e.g., press releases and sustainability ...

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

Carbon 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 ...
