Synergizing Polysulfide Trapping and Fast Ion Kinetics Enabled by Poly(Acrylamide‐co‐Lithium Acrylate) Aqueous Binder for High‐Sulfur‐Loading Lithium–Sulfur Batteries

open access: yesSmall, EarlyView.
A water‐soluble AmLA binder anchors lithium polysulfides and reinforces sulfur cathodes by combining amide and lithium acrylate functional groups. The dual‐function network retards polysulfide dissolution in operando and preserves electrode integrity under large volume changes.

Defects That Magnetize Beyond Monolayer PtSe2

open access: yesSmall, EarlyView.
The presence of a complex point defect consisting of a Pt vacancy (black circle) and a PtSe antisite (red circle) revives and increases the quenched magnetism in bilayer PtSe2. Magnetic properties can be further modulated by the presence of an Se vacancy (blue circle), which can convert the ferromagnetic behavior into antiferromagnetic when it occurs ...

Manganese Oxide Catalysts for Lithium–Oxygen Batteries: Structures, Mechanisms, and Reaction Pathway Engineering

open access: yesSmall, EarlyView.
How do the morphologies, crystal structures, and electronic properties of manganese oxides influence oxygen reaction pathways in lithium–oxygen batteries (LOBs)? This review systematically summarizes structure‐dependent catalytic mechanisms and recent engineering strategies, highlighting how defect engineering, compositional modulation, and reaction ...

Highly integrated, alignment healing, and full‐recyclable multifunctional flexible devices based on dynamic covalent bonds

open access: yesSmart Molecules, EarlyView.
This study addresses stability, repair, and recycling in flexible devices using polymers with identical dynamic bonds but incompatible backbones. This enables robust integration, precise self‐healing, and full recyclability. We demonstrate optoelectronic sensors that, after damage, magnetically self‐assemble and heal upon heating.

Recycling‐Induced Copper Contamination of a 42CrMo4 Quench and Tempering Steel—Scaling and Susceptibility to Hot Shortness

open access: yessteel research international, EarlyView.
In this study, the susceptibility to copper‐induced hot shortness of the alloy 42CrMo4 is investigated by different hot tensile tests, as well as by a detailed analysis of the formed oxidation products. While an enrichment of metallic copper and a penetration of the grain boundaries are observed, no critical reduction of the tensile test properties can
