Buried Interface Engineering via a Bifunctional Guanidino‐Carboxyl Molecular Bridge for Enhanced Performance and Stability in Perovskite Solar Cells

EcoEnergy, EarlyView.
A bifunctional molecular bridge using 4‐guanidinobutanoic acid (GCC) is constructed to comprehensively tailor the buried interface of PSCs. By passivating oxygen vacancies, optimizing energy‐level matching, and regulating perovskite crystallization, this strategy simultaneously boosts the power conversion efficiency to 25.37% (20.01% for 13.4 cm2) and ...

Synthesis of Single‐Crystalline Ni‐Rich Cathodes for Lithium‐Ion Batteries With Superior High‐Voltage Stability by Mo/Nb Dual Doping

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A novel synthesis method of single‐crystalline LiNi0.8Co0.15Al0.05O2 (NCA) is introduced, involving the stripping of grain boundaries from polycrystalline NCA (PC‐NCA) during Mo/Nb co‐doping. Mo doping near the grain surface significantly reduces parasitic interface reactions and inhibits the excessive growth of CEI films, while Nb doping within the ...

Diphenyl Disulfide‐Promoted Racemization of 1‐Arylethanols for Photobiocatalytic Dynamic Kinetic Resolution

European Journal of Organic Chemistry, EarlyView.
Purple‐light activation of aggregated diphenyl disulfide unlocks the photocatalyst‐free racemization of 1‐arylethanols. The resulting sulfur radical process operates under mild conditions and couples with the enzymatic acylation by Candida antarctica lipase B in a photobiocatalytic dynamic kinetic resolution, revealing new opportunities for sulfur ...
