Electrochemical CO2RR is a key technology for converting CO2 into chemicals, but there remains a gap between “laboratory science” and “engineering practice” in current research. This review establishes a multi‐scale research framework, encompassing atomic‐level characterization, microenvironment regulation, external field‐assisted optimization, and AI ...

Magnetic tunnel junctions (MTJs) using MgO tunnel barriers face challenges of high resistance‐area product and low tunnel magnetoresistance (TMR). To discover alternative materials, Literature Enhanced Ab initio Discovery (LEAD) is developed. The LEAD‐predicted materials are theoretically evaluated, showing that MTJs with dusting of ScN or TiN on ...

Guest‐Induced Activation of Multicolor Photoluminescence in Naphthalene Bisimide Liquid Crystals
Supramolecular host–guest design in naphthalene bisimide liquid crystals activates charge‐transfer emission and enables continuous tuning of color (511–685 nm) and lifetime, spanning prompt fluorescence, TADF, and RTP. Electron‐rich guests and Pt(II) complexes modulate emissive states, while co‐assembled NBI complexes create an energy‐transfer cascade ...
