Photochromism‐Driven Full Solar Spectrum Absorption for Efficient Photo‐Thermo‐Electric Conversion

open access: yesAdvanced Science, EarlyView.
After electron‐transfer photochromism, a black viologen‐based organic compound shows full solar spectrum absorption (250–2500 nm) and near‐infrared photothermal conversion efficiency (NIR‐PCE) >60%. Integrated with a thermoelectric generator, it outputs 1.17 V under 4 Suns irradiation, enough to drive a small fan via photo‐thermo‐electric conversion ...

Large Anomalous Hall Effect, Non‐Vanishing Berry Curvature in (110) FeRh Antiferromagnet Films via Interface Strain

open access: yesAdvanced Science, EarlyView.
This study demonstrates a strain‐tunable anomalous Hall response in the (110)‐oriented FeRh thin film. First‐principles calculations reveal that strain‐induced symmetry lowering redistributes Berry curvature near the Fermi level via band shifts and avoided crossings.

Interconnected Hierarchically Porous Graphene‐Based Membrane Electrode for High‐Power and Long‐Cycle Lithium–Oxygen Battery

open access: yesAdvanced Science, EarlyView.
Lithium–oxygen batteries face an energy‐power trade‐off due to sluggish O2 transport and pore clogging by Li2O2. Simulations show that reducing tortuosity via interconnected macropores enhances oxygen mobility. A freestanding graphene electrode having interconnected macropores with low tortuosity delivers >2500 mAh g−1, stable lean‐electrolyte cycling,

A Multifunctional Potent Lewis Acid for In Situ Formation of Poly‐Dioxolane Electrolytes Toward High‐Performance Quasi‐Solid State Lithium Metal Batteries

open access: yesAdvanced Science, EarlyView.
Conventional polymer electrolytes based on poly‐dioxolane (PDOL) suffer from low ion mobility and unstable interfaces. Here, AlCl3‐initiated in situ polymerized gel PDOL electrolytes (AGPE) form a facile Li+ conduction path and hybrid SEI layers, thus enabling high Li+ conductivity and uniform Li deposition.
