Stable Catholyte Interface Enables Practical Operation of Sulfide‐Based All‐Solid‐State Li Metal Batteries

Advanced Energy Materials, EarlyView.
A conformal fluorocarbon self‐assembled monolayer on Li6PS5Cl protects the solid electrolyte from degradation by polar solvents and moisture. This surface stabilization allows scalable slurry processing and stable cycling even under low pressure, offering a practical pathway to high‐performance all‐solid‐state batteries. Abstract Achieving chemical and

Rubber friction on smooth surfaces

, 2006
We study the sliding friction for viscoelastic solids, e.g., rubber, on hard flat substrate surfaces. We consider first the fluctuating shear stress inside a viscoelastic solid which results from the thermal motion of the atoms or molecules in the solid.

Phase‐Change Alloys Enable Localized Reversible Stiffening and Actuation in Steerable Eversion Tip‐Growing Robots

Advanced Intelligent Systems, EarlyView.
This work presents a tip‐growing eversion robot that uses phase‐changing alloys for reversible stiffening and localized actuation, achieving 43× stiffness modulation, 15× force amplification, and segmental steering. The system enables precise navigation and force delivery in constrained, tortuous pathways.

A Photoredox Radical‐Polar Crossover Reaction for the Preparation of Monoprotected Dicarbonyl Compounds

European Journal of Organic Chemistry, EarlyView.
An ATRA‐based, Ru‐photocatalyzed radical‐polar crossover reaction for the preparation of monoprotected dicarbonyl compounds is reported. This procedure is based on the capture of a cationic intermediate, arising from the radical step, with diverse nucleophiles.
