Multifunctional MXene/C Aerogels for Enhanced Microwave Absorption and Thermal Insulation
Nano-Micro Letters, 2023 Curving 2D MXene into 1D nanofibers can effectively stop the restacking of MXene flakes, and then the nanofibers are used to construct a lightweight and multifunctional MXene/C aerogel. The MXene/C aerogels achieved an RL_min of − 53.02 dB and EAB of 5.3

Exceptional topological insulators [PDF]
Nature Communications, 2021 AbstractWe introduce the exceptional topological insulator (ETI), a non-Hermitian topological state of matter that features exotic non-Hermitian surface states which can only exist within the three-dimensional topological bulk embedding. We show how this phase can evolve from a Weyl semimetal or Hermitian three-dimensional topological insulator close ...

Impact Sound Insulation of Thermally Insulated Balconies
INTER-NOISE and NOISE-CON Congress and Conference Proceedings, 2022 AbstractWith the increasing urban densification, balconies are gaining in popularity as they improve the living quality in homes. From a technical point of view, the thermal insulation between balconies and the building’s façade is state of the art. In Germany, the most popular balcony construction is a reinforced concrete balcony, separated from the ...
