Shannon and Rényi Entropies of Molecular Densities Under Atomic Partitioning: Insights Into Extensity and an Incomplete Description of Electron Correlation

International Journal of Quantum Chemistry, Volume 126, Issue 10, May 15, 2026.
At infinite separation, a diatomic molecule reduces to two noninteracting subsystems. The electron density decomposes into atomic densities, while the Rényi entropy functional reveals both additive atomic contributions and nonadditive terms. None of these terms contains any trace of the presence of static correlation effects, particularly important in ...

Approaching Sixfold Chemical Bonding: Metal Dimers MM' Involving Group 4–8 Transition Metals and the Actinides Th–Np. Additive Covalent Radii r6$r_6$

Chemistry – A European Journal, Volume 32, Issue 18, 14 May 2026.
Twelve‐valence‐electron transition metal dimers MM', like diatomic Mo2, can have nearly sixfold bonds. Values of r6$r_6$ for over 20 elements from Sc to Pu are proposed. ABSTRACT A set of additive covalent radii is fitted to a combination of experimental data, accurate ab initio computations, and more approximate DFT MM' bond lengths, R$R$, with 12 ...

Forging Sustainable Carbon–Nitrogen Bonds from CO2 and NOx: Mechanistic Insights and Catalyst Design for Electrochemical CN Coupling

ChemSusChem, Volume 19, Issue 9, 14 May 2026.
Electrochemical CN coupling enables the direct conversion of CO2/CO and NOx into value‐added organonitrogen compounds under mild and sustainable conditions. Catalyst architecture governs the coactivation of carbon and nitrogen intermediates and their interfacial coupling, dictating reaction pathways, selectivity, and efficiency.

Bioinspired Stabilization of Fluorescent Au@SiO2 Tracers for Multimodal Biological Imaging

Advanced Functional Materials, Volume 36, Issue 38, 11 May 2026.
This study demonstrates a bioinspired stabilization strategy for fluorescent gold‐silica nanoparticles. Inspired by natural biosilica maturation, high‐temperature calcination transforms the silica shells, preventing dissolution in cell culture media and intracellular environments.

Structure Formation in Butterfly Scales: Interplay of Genetic Control, Mechanical Instabilities, and Dynamic Material Properties

Advanced Functional Materials, Volume 36, Issue 38, 11 May 2026.
Butterfly wing scales are intricate cuticular functional nanosctructures. This perspective suggests that spatially varying material properties, cytoskeletal constraints, and growth‐driven mechanical instabilities shape the resulting nanoscale architectures created from single cells.
