Co3O4/C‐NFs Induced 3D Electric Field Enhancement for Dual‐Regulation of Polysulfides and Li+ Transport in Lithium–Sulfur Batteries

open access: yesAdvanced Science, EarlyView.
A nano‐framework structured Co3O4/C catalyst with 3D electric field enhancement is designed to facilitate the mass transfer of both Li⁺ and lithium polysulfides (LiPSs) in lithium–sulfur batteries (LSBs). The enhanced electric‐field–driven migration significantly accelerates sulfur reduction reaction (SRR) kinetics while suppressing the shuttle effect ...

NADH‐Reductive Stress Induced by Dihydrolipoamide Dehydrogenase Activation Contributes to Cuproptosis

open access: yesAdvanced Science, EarlyView.
This study demonstrates a cuproptosis mechanism involving nicotinamide adenine dinucleotide (NADH)‐reductive stress in neural cells. Copper activates dihydrolipoamide dehydrogenase under mitochondrial pH, accumulating NADH. Copper also induces mitochondrial permeability transition pore opening, facilitating NADH translocation to the cytosol and ...

Passivation‐Induced Species Dynamics and Microstructural Evolution in Solid‐State Lithium–Sulfur Cathodes

open access: yesAdvanced Science, EarlyView.
The formation of insulating Li2S during discharge in solid‐state lithium–sulfur batteries passivate reaction sites and limits sulfur utilization. In this work, a microstructure‐resolved modeling framework coupling transport and reaction kinetics is developed to predict charge–discharge behavior and reveal particle‐scale species evolution and incomplete
