Twisted Homobilayers
In article number 2305200, Pengfei Qi, Zheyu Fang, and co‐workers have systematically studied the nonequilibrium dynamics of indirect exciton in homobilayers. The homobilayers with slightly twist‐angle can induce a deep moiré potential (>50 meV) in energy landscape, resulting in a strongly localized moiré excitons insulating the transport dynamics from phonons and disorder...
Artificially molding exciton flux is the cornerstone for developing promising excitonic devices. In the emerging hetero/homobilayers, the spatial separated charges prolong exciton lifetimes and create out‐plane dipoles, facilitating electrically control exciton flux on a large scale, and the nanoscale periodic moiré potentials arising from twist‐angle or/and lattice mismatch can substantially alter...
Mechanoluminescence (ML) materials present widespread applications. Empirically, modulation for a given ML material is achieved by application of programmed mechanical actuation with different amplitude, repetition velocity and frequency. However, to date modulation on the ML is very limited within several to a few hundred hertz low‐frequency actuation range, due to the paucity of high‐frequency mechanical...
The enormous overpotential caused by sluggish kinetics of the oxygen reduction reaction and the oxygen evolution reaction prevents the practical application of Li–O2 batteries. The recently proposed light‐assisted strategy is an effective way to improve round‐trip efficiency; however, the high‐potential photogenerated holes during the charge would degrade the electrolyte with side reactions and poor...
The efficacy of immune checkpoint inhibition in inducing death of cancer cells is affected by the immunosuppressive “cold” tumor microenvironment, which results in a poor response by the patient's antitumor immune system. However, the immunomodulatory effects of immunogenic cell death in response to irritation by heat energy and reactive oxygen species (ROS) can switch the tumor microenvironment from...
