Human hair keratin responds to oxidative stress via reactive sulfur and supersulfides

Advances in Redox Research
Keratin is a central component of human hair proteins, which explicitly possesses many cysteine residues (Cys-SH). For a long time, these Cys-SH residues were believed to contribute to human hair strength by forming intra- and inter-molecular disulfide ...

Anode-Free Lithium-Sulfur Cells Enabled by Rationally Tuning Lithium Polysulfide Molecules.

Angewandte Chemie, 2022
The two major barriers of practical lithium-sulfur batteries are the poor reversibility of lithium-metal anode and sluggish kinetics of sulfur cathode. Here, we report a simple yet cogent, molecular tailoring approach for lithium polysulfides, enabling a

Unravelling the Secret of Sulfur Confinement and High Sulfur Utilization in Hybrid Sulfur‐Carbons

Advanced Materials, EarlyView.
Thermal condensation of inverse vulcanized sulfur‐carbon hybrids enables a bottom‐up sulfur confinement strategy, in which a protective carbon phase is progressively constructed around sulfur species. The resulting carbon nanodomains covalently tether sulfur chains and stabilize radical intermediates. This integrated architecture effectively suppresses

Molecular Surface Engineering of Sulfide Electrolytes with Enhanced Humidity Tolerance for Robust Lithium Metal All‐Solid‐State Batteries

Advanced Materials, EarlyView.
It is demonstrated that the electrochemical, interfacial, and humidity stability of halide‐doped sulfide electrolytes (LPSClBr) is significantly enhanced by an organic surface coating using octadecyl phosphonic acid (OPA) and its lithiated form (Li‐OPA). This single‐step strategy enables robust interfacial protection, supports lithium metal anodes, and
