Cobalt‐Catalyzed C─N Bond Formation via Metal‐Hydride Hydrogen Atom Transfer (MHAT)

Angewandte Chemie, EarlyView.
Cobalt‐catalyzed metal‐hydride hydrogen atom transfer (Co‐MHAT) converts simple alkenes into C─N bonds under mild, near‐neutral conditions. A shared Co─H‐initiated radical/organocobalt intermediate is channeled into radical trapping, radical‐polar crossover, or radical ligand transfer, unifying hydroamination, hydroazidation, hydroamidation, and remote

A National Survey of Informal Supporters' Experiences and Views of Behaviour Support Practitioners in the National Disability Insurance Scheme

Australian Journal of Social Issues, EarlyView.
ABSTRACT This study examines informal supporters' experiences and views of NDIS behaviour support practitioners, including engagement, information needed to support selection, and perceptions of practitioners' knowledge, skill, and practice. It reports data from a cross‐sectional online survey of 123 informal support providers of participants receiving

S‐Scheme Charge Separation Enables Photocarrier‐Regulated Aqueous NH4+ Storage in g‐C3N4@WO3 Heterojunctions

Angewandte Chemie, EarlyView.
Light irradiation activates the g‐C3N4@WO3 S‐scheme heterojunction, where the built‐in electric field drives charge separation to generate high‐energy carriers, facilitating NH4+ adsorption and enhancing electron/ion transport for high‐capacity, stable aqueous NH4+ storage.

A novel method for treating MAR in EMC3-Eirene, and first applications to W7-X

Nuclear Fusion
This paper presents a novel ‘prediction-correction method’ for treating molecule-assisted recombination (MAR) in the three-dimensional (3D) boundary plasma transport code—EMC3-Eirene.

Early Endoscopic Repair of Traumatic Skull Base Dural Injuries: Challenging the Dogma of Conservative Management

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Introduction Traditional management of traumatic skull base dural injury has often favored observation and conservative therapy, despite the risk of delayed intracranial complications. This paradigm originated when operative intervention required craniotomy and carried significant morbidity.

Epitaxial Oxide Interfaces Create Poison‐Resistant CuO Sites for Environmental Catalysis

Angewandte Chemie, EarlyView.
An epitaxially stabilized CuO overlayer on Ti1−xInxO2 creates electron‐poor, high‐symmetry Cu–O sites that activate interfacial lattice‐oxygen redox. This interface promotes NOx reduction through an Eley–Rideal pathway, diverts sulfate formation, and sustains CH3SH deep oxidation via a Mars–van Krevelen cycle, offering a route to poison‐resistant ...

LHD Helical Divertor

"The Large Helical Device (LHD) now under construction is a heliotron/torsatron device with a closed divertor system. The edge LHD magnetic structure has been studied in detail. A peculiar feature of the configuration is existence of edge surface layers ,

Radical, Not Ionic: The Mechanochemical Zincke Nitration of Phenols

Angewandte Chemie, EarlyView.
Mechanochemistry recasts the classical Zincke nitration as an open‐shell process. Liquid‐assisted vibrational milling of phenols with in situ HNO2 delivers direct and ipso nitration across 50 substrates, while atmosphere, NOx‐transfer, EPR and DFT evidence expose a phenoxyl‐radical/NO2 manifold underlying this historically ionic transformation ...

Chlorination‐Driven BODIPY Fluorescent Probes for the Selective Monitoring of Myeloperoxidase Activity in Cells and Inflamed Mouse Models

Angewandte Chemie, EarlyView.
A meso‐carboxamide‐substituted BODIPY fluorescent probe reports myeloperoxidase (MPO) activity via electrophilic chlorination by MPO‐derived HOCl, generating a highly emissive chlorinated product with a ca. 40 nm bathochromic shift. Applications in quantitative MPO assays, cellular imaging of MPO‐derived HOCl, redox‐dependent discrimination of cancer ...
