Nickel‐Catalyzed Three‐Component Difluoroalkylation‐Amination for the Direct Access to Anti‐Inflammatory β‐Difluoroalkyl Amines

open access: yesAdvanced Science, EarlyView.
A nickel‐catalyzed three‐component reductive fluoroalkylation‐amination strategy of N‐vinylamides for the direct access to the α‐amidyl‐β‐difluoroalkyl amines was reported here. The synthetic method features with broad substrate scope, mild conditions, high functional group tolerance, and convenience to handle.

Battery‐Inspired Electrochemical Synapses for Neuromorphic Applications

open access: yesAdvanced Science, EarlyView.
Battery‐ion‐inspired synaptic devices integrate diverse electrolyte systems (solid, ion‐gel, liquid) with transition metal oxides, two‐dimensional materials, and organic channels to regulate ion‐electron coupling. By tailoring ion transport and host interactions, these platforms enable controllable plasticity and energy‐efficient implementations for ...

USP30‐Mediated Deubiquitination of PEX5 Suppresses Pexophagy to Drive Tubular Injury in Diabetic Kidney Disease

open access: yesAdvanced Science, EarlyView.
USP30 accumulation in diabetic renal tubular epithelial cells deubiquitinates PEX5, suppresses pexophagy, and drives dysfunctional peroxisome accumulation and tubular injury. USP30 depletion restores PEX5 ubiquitination and pexophagy, improves peroxisomal function, and alleviates tubular damage, highlighting USP30 as a therapeutic target in diabetic ...
