ALDH Inhibition‐Primed Photocatalysis Disrupts Cancer Stemness Plasticity
Angewandte Chemie, EarlyView.DE‐Et converts ALDH‐mediated redox buffering into a photoredox vulnerability by coupling ALDH inhibition with red‐light‐driven catalytic NADH oxidation. This enzyme‐coupled photoredox strategy sustains mitochondrial NADH/NAD+ imbalance, induces pyroptotic tumor cell death, suppresses tumor growth in vivo, and promotes systemic antitumor immunity ...

Frequency-comb-induced radiation pressure force in dense atomic clouds
, 2021 We investigate the frequency comb induced radiation pressure force acting on a cloud of cold $^{87}$Rb atoms. Reduction and spectral broadening of the frequency comb force are observed as the cloud's optical thickness is increased.

Multi‐Li+ Coordination for Superior Room‐Temperature Ionic Conductivity in PEO Solid Electrolytes
Advanced Materials, EarlyView.A phosphonate‐functionalized polycarboxylate ether (P‐PCE) is introduced into PEO electrolytes to induce multi‐Li+ ions coordination, which effectively dissociates lithium salts, liberates Li+ from the strong chelation by PEO chains, and promotes fast Li+ hopping between adjacent coordination sites. Simultaneously, this design establishes dynamic, high‐
