2D organic semiconductors are widely believed to have uniformly active surfaces. This study reveals that their basal planes can be pseudo‐inert due to anisotropic exciton migration. By inducing exciton self‐trapping through dimensional reduction, these inert planes are activated, boosting hydrogen peroxide production by over 350%. The work uncovers key

Nickel Hydroxide Catalyzed Bias‐free Photoelectrochemical NH3 Production via Nitrate Reduction
A bias‐free photoelectrochemical nitrate reduction reaction with high efficiency and production rate is achieved using a crystalline silicon photocathode with nickel as the catalyst. Performing the PEC NO3RR under alkaline conditions can be self‐activated of the Ni surface by forming Ni(OH)2.

Active Diffusion Controlled Dual Stability in Thermoelectrics for Sustainable Heat Harvesting
Introducing a Mg interlayer at the junction simultaneously stabilizes Mg3(Bi,Sb)2 materials and contacts for over 100 days. This dual stabilization derives from suppressing detrimental Mg diffusion and compensating for Mg loss, thereby maintaining an outstanding power density of 0.45 W cm−2 and remarkable conversion efficiency of 8.6% in aged modules ...

Ultrathin amorphous alumina electrocatalyst overlayers block oxygen reduction while cathodic‐driven structural relaxation accelerates proton transport over time. By contrast, ultrathin aluminosilicate coatings allow proton permeation but cannot suppress oxygen.

Molecular dynamics simulations are employed to model ion concentration polarization (ICP) at the nanoscale, revealing fundamental electrokinetic behaviors that align with experimental observations. The study demonstrates how membrane charge, ionic strength, and electric fields affect ion localization and biomolecule trapping, providing mechanistic ...
