One‐Step Radical‐Intensified Selective Etching (RISE) Strategy for High‐Yield Synthesis of Monolayer MXene with Tailored Nanoholes

Angewandte Chemie, Volume 138, Issue 25, 15 June 2026.
Radical‐intensified selective etching (RISE) delivers monolayer MXenes with >80% yield in just 3 h etching process. Controlled ·OH dosage enables one‐step access to holey MXenes with abundant nanopores or defect‐lean flakes. This mild, safe strategy couple ultrafast kinetics with structural tunability, advancing precision design of MXene architectures.

Contra‐Diffusion Engineering of Single‐Atom Catalytic Interlayers Enables Reversible Sulfur Redox Chemistry

Angewandte Chemie, Volume 138, Issue 24, 8 June 2026.
A contra‐diffusion strategy is introduced to grow uniformly distributed Co–Nx single‐atom catalysts (CoSAs) within a carbonized aramid nanofiber (CANF) interlayer. The resulting CD‐CANF enables efficient polysulfide regulation, low metal loading, and exceptional long‐term cycling stability in lithium–sulfur batteries. ABSTRACT Achieving durable lithium–

Reduction of Oxide Inclusions During the High‐Frequency Welding of Steel via a Nonthermal Ar/H2 Plasma Jet

Advanced Engineering Materials, Volume 28, Issue 12, 17 June 2026.
High‐frequency (HF) welding of steel is limited by oxide inclusions that degrade weld quality. This study demonstrates, for the first time, the integration of a nonthermal Ar/H2 dielectric barrier discharge (DBD) plasma jet into HF welding. Local plasma treatment provides effective shielding and in‐situ oxide reduction, resulting in markedly fewer and ...
