Optoelectronics of Single Mixed Dislocations in Van Der Waals Core‐Shell Nanowires

Small, Volume 22, Issue 44, 7 August 2026.
Ge1‐xSnxS van der Waals core‐shell nanowires can host single helical dislocations whose character is tunable from a pure screw to a majority edge dislocation via the core‐shell lattice mismatch. Cathodoluminescence shows profound effects once an edge component is introduced, notably a lowering of the spontaneous emission quantum efficiency due to the ...

Isolation of a Highly Reactive CBNC Heterocumulene via Azidoborylene Photolysis: Facile Access to a Crystalline Dioxaborirane

Angewandte Chemie, Volume 138, Issue 29, 13 July 2026.
Azidoborylene photolysis results in the isolation of a reactive C═B═N═C heterocumulene bearing an ambiphilic boron centre. Addition of 3O2 to this species results in the clean conversion to a unique example of a dioxaborirane. ABSTRACT Oxidation of the formal boron(0) complex MeCAAC2B in the presence of tetrabutylammonium azide leads to the formation ...

Encyclopedia of 2D β′‐In2Se3 Growth Using Chemical Vapor Deposition: The Effects of Synthesis Parameters Onto Material Quality

Advanced Engineering Materials, Volume 28, Issue 14, 22 July 2026.
A distinct semi‐confined inner‐tube chemical vapor deposition geometry enables reproducible, large‐area growth of phase‐pure 2D β′‐In2Se3 from InI + Se precursors. Engineering local vapor transport and optimizing precursor delivery and temperature–time conditions yield uniform continuous films.

Catalytic Antioxidant Activity of Acyclic and Macrocyclic Selenides: Insights Into Structure–Activity Relationships and Mechanisms From Kinetic and Computational Studies

European Journal of Organic Chemistry, Volume 29, Issue 27, 17 July 2026.
Structure–activity relationships of antioxidant activities of selenides were established by experimental and computational methods. Several structures displayed strong catalytic activity in an NMR‐based assay. Diverse selenides were shown to act as potent catalytic antioxidants.

Thioredoxin Reductase as a Target for Antibacterial Gold Compounds in Burkholderia cenocepacia: Disclosing the Molecular Basis of Enzyme Inhibition

ChemBioChem, Volume 27, Issue 13, 14 July 2026.
The molecular basis of thioredoxin reductase inhibition by antibacterial gold(I) compounds is disclosed. X‐ray crystallography and high‐resolution ESI‐MS reveal selective gold coordination to catalytically relevant cysteine residues of Bc‐TrxR, leading to stable protein–gold adducts and disruption of enzyme redox activity.

Expansion of the Metal‐Involving Noncovalent Interaction Repertoire: The Case of Pd(II) and Pt(II) Triel Bonding

ChemPhysChem, Volume 27, Issue 13, 14 July 2026.
This study reveals that square planar Pd and Pt complexes can act as nucleophiles, forming directional triel bonds with boron‐based acceptors. Using energy decomposition analysis (EDA), quantum theory of atoms in molecules (QTAIM), and natural bond orbital (NBO), we demonstrate a transition from dispersion‐driven to dative‐covalent interactions.
