Atomically precise metal cluster enzymes for pathological tissue regeneration

BMEMat, EarlyView.
Schematic illustration of atomically precise metal cluster enzymes (MCEs) for pathological tissue regeneration. Atomically precise MCEs can modulate biological processes, such as attenuation of inflammatory responses, eradication of bacterial pathogens, regulation of angiogenesis, and promotion of cell development.

Highly Functionalized 1,2–Diamino Compounds through Reductive Amination of Amino Acid-Derived β–Keto Esters

PLoS ONE, 2013
1,2-Diamine derivatives are valuable building blocks to heterocyclic compounds and important precursors of biologically relevant compounds. In this respect, amino acid-derived β-keto esters are a suitable starting point for the synthesis of β,γ-diamino ester derivatives through a two-step reductive amination procedure with either simple amines or α ...

The Stabilization of High‐Nitrogen Systems: 10 Catenated Nitrogen Chain

Chemistry – A European Journal, EarlyView.
Improving the understanding of high‐nitrogen materials. ABSTRACT High‐nitrogen materials have attracted intense interest in recent decades due to their unique chemical, physical, and biological properties. Stabilizing high‐nitrogen materials is often challenging as they become more unstable with increasing nitrogen catenation and nitrogen mass ...

A New Spin on Photocatalysis: Vortex Fluidic‐Driven Photooxidations Enabled by Solution‐Processable Microporous Polymers

Chemistry – A European Journal, EarlyView.
Newly developed polymers with intrinsic microporosity (PIMs) were combined with benzo[c][1,2,5]thiadiazole (BTZ) to be used as visible light photocatalytic coatings on the Vortex Fluidic Device (VFD). The VFD's rapid rotation and continuous flow capabilities enhanced singlet oxygen and superoxide radical reactions, achieving a dramatic eightfold ...

Synthesis and Structures of Novel Chiral Cyclic Hypervalent Iodine(III) Reagents for Metal‐Free Ligand‐Transfer Reactions

Chemistry – A European Journal, EarlyView.
Several new chiral cyclic hypervalent iodine(III) reagents have been synthesized and characterized. Carbon‐based ligands were successfully installed onto the hypervalent iodine centers, giving thus access to novel chiral cyano‐, trifluoromethyl‐ or alkynyl‐bearing λ3‐iodanes.

Asymmetric Iron‐Catalyzed Vicinal C(sp3)─H Diamination of Carboxylic Acids

Angewandte Chemie, Volume 138, Issue 32, 3 August 2026.
An iron‐catalyzed vicinal α,β‐C(sp3)─H diamination of readily available carboxylic acids furnishes chiral α,β‐diamino acids in a single pot with high regio‐, diastereo‐, and enantioselectivity (up to >20:1 dr and >99% ee). ABSTRACT The direct construction of chiral 1,2‐diamines through the stereoselective functionalization of two vicinal C(sp3)─H bonds

Basalt Fiber Surface Modification for Improved Interaction With Polyamide‐6 for High‐Performance Automotive Applications

Polymer Composites, EarlyView.
Amino‐silane treatment improves the basalt fiber–PA6 interface, enhancing composite performance. ABSTRACT Basalt fiber‐reinforced polymer (BFRP) composites have emerged as sustainable alternatives to glass fiber (GF) composites, but their performance is often controlled by the quality of the fiber–matrix adhesion.

Carbonized polymer dots with aqueous‐stable room‐temperature phosphorescence: Mechanism, matrix engineering, and application

Responsive Materials, EarlyView.
This review focuses on inorganic and organic matrices that enable aqueous‐stable room‐temperature phosphorescence (RTP) in carbonized polymer dots (CPDs). It explains the underlying RTP mechanisms, highlights how matrix engineering provides spatial confinement and bonding interactions to stabilize triplet excitons in water, and demonstrates key ...
