Angewandte Chemie, Volume 138, Issue 43, 19 October 2026.Efficient photocatalytic nitrate‐to‐ammonia conversion is achieved over an atomically precise Cu4I4 motif through dual‐site cooperation. Lewis‐acidic Cu centers promote nitrate adsorption and activation, while adjacent I sites facilitate active hydrogen generation for stepwise hydrogenation.

Suppression of Oscillation and Ghosting in RF‐Spoiled Gradient‐Echo‐Based Dynamic Imaging
Magnetic Resonance in Medicine, Volume 96, Issue 5, Page 2177-2187, November 2026.ABSTRACT PurposeThis study aims to address the suppression of oscillation and ghosting appearing in RF‐spoiled gradient‐echo‐based dynamic imaging, which is caused by the pseudo‐steady state (PSS) of magnetization. Theory and MethodsWe extended the concept of the previous RF phase‐cycle‐adapted averaging method to RF‐spoiled gradient‐echo‐based cine ...

The Impact of BOLD‐Induced Linewidth Modulation on Functional 1H MRS Analysis
NMR in Biomedicine, Volume 39, Issue 11, November 2026.Functional MRS studies face a technical challenge: BOLD‐related lineshape changes can be mistaken for genuine metabolic changes, causing ~1% glutamate estimation bias at 3 and 7 T across conventional (LCModel, ABfit‐reg) and 2D fitting methods. Using synthetic data, this study shows that explicit BOLD linewidth correction—via dynamic lineshape ...

Angewandte Chemie, Volume 138, Issue 43, 19 October 2026.High‐loading tin single‐site catalysts (>7.5 wt.% Sn) are synthesized using a nitrogen‐enriched carbon scaffold and mechanochemically assisted pyrolysis to stabilize atomically dispersed Sn. The resulting Sn/N‐C‐M catalyst enables highly selective CO2‐to‐formate conversion (>90% FE across 50–500 mA cm−2) with long‐term durability and operando‐verified ...

Chemistry – A European Journal, Volume 32, Issue 40, 27 October 2026.We present a two‐dimensional conductive metal‐organic framework (2D cMOF) constructed from an organic linker with lower symmetry than those commonly used in related systems. The resulting reduction in lattice symmetry lifts band degeneracies, reshapes the electronic structure, and opens a larger band gap.

A Multi‐Scale Machine Learning Framework for the Inverse Design of High Entropy Alloys
Advanced Engineering Materials, Volume 28, Issue 20, 21 October 2026.High‐entropy alloys offer vast potential for various applications, including electrocatalysis; however, their compositional complexity challenges conventional screening. We introduce an inverse‐design framework combining two neural networks to determine optimal compositions and reconstruct nanoparticle geometry from targeted properties and conventional
