A Radical Cascade with Double Intramolecular Hydrogen Atom Transfer for the Generation of Bisfunctionalized Cyclopentanes from Linear Alkynes

Angewandte Chemie, Volume 138, Issue 5, 28 January 2026.
A radical cascade process involving the activation of two aliphatic C–H bonds in a series of five elementary steps converts readily available terminal alkynes into functionalized cyclopentylmethyl arylsulfones. The methodology delivers flexible synthetic intermediates and was applied to the preparation of diquinanes and triquinanes possessing a rare ...

Residual Chemical Shift Anisotropies in the Structure Determination of Small Molecules

Magnetic Resonance in Chemistry, Volume 64, Issue 3, Page 286-311, March 2026.
Plasma neutrophil elastase(ELANE) was markedly elevated in patients with alcohol use disorder, indicating a dysregulated protease‐antiprotease inflammatory balance characterised by decreased SERPINA3. ELANE showed excellent diagnostic specificity(AUC = 0.8683), supporting its potential utility as a neuroinflammatory biomarker for AUD.

Exploring the World of Double Nanohoops

Angewandte Chemie International Edition, Volume 65, Issue 6, 2 February 2026.
As two conjugated nanohoops covalently linked by a central unit, double nanohoops are a relatively new class of strained nanocarbons with different properties to single nanohoops. This review gives an overview of all reported double nanohoops, categorizing their structures, syntheses, and discussing properties and applications. Creativity and synthetic

Spectroscopic Ellipsometry Characterization and Radiative Limit Modeling of Bismuth‐Based Perovskite‐Inspired Absorbers for Indoor Photovoltaics

Advanced Optical Materials, Volume 14, Issue 5, 2 February 2026.
This study determines the optical constants of two lead‐free perovskite‐inspired materials (PIMs), Cu2AgBiI6 and Cs3Bi2I6Br3, promising for indoor light conversion. The optical constants are applied to simulate photovoltaic device optics, and thereupon, revise the theoretical limits for photocurrent generation and power conversion efficiency, providing
