Red era: Dyeing yak hair fibres red with in situ generated silver nanoparticles using silver nitrate and a flavonoid‐containing plant extract

Coloration Technology, EarlyView.
Abstract Plants and their extracts have been used for dyeing fabrics, skin and hair for thousands of years and have been experiencing a revival in the last years due to increasing health risks arising from oxidative hair dye precursors. We developed a novel two‐step method to dye keratin fibres based on in situ formed silver nanoparticles including a ...

A new branch of mammalian vitamin B6 metabolism: AKR1C‐mediated conversion of pyridoxal to pyridoxine and 4‐pyridoxolactone

The FEBS Journal, EarlyView.
Pyridoxal 5′‐phosphate (PLP) homeostasis relies on salvage enzymes, yet key metabolic branches remain undefined. We identify AKR1C isozymes as previously undescribed contributors that convert pyridoxal into pyridoxine or 4‐pyridoxolactone through reductase and dehydrogenase activities.

A Comparative Analysis of Maillard‐Derived α‐Dicarbonyl Compounds and Advanced Glycation End Products in Fresh, Wet, Kibble, and Freeze‐Dried Dog Foods

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Thermal processing of pet foods can lead to the formation of harmful Maillard reaction products (MRPs), which may compromise nutritional quality and pose health risks to companion animals. This study compared the levels of MRPs in 41 commercial dog foods, including fresh (n = 15), kibble (n = 13), wet (n = 10), freeze‐dried (n = 2), and cold ...

Surface‐Engineered Dual‐Emission of Carbon Dots for Ratiometric Detection of Hydroxyl Radicals

Nanophotonics, Volume 15, Issue 9, 13 May 2026.
Oxidation‐engineered CDs with tunable dual emission (450/590 nm) exhibit oxidation state‐driven electron redistribution and core‐to‐surface transfer within 5 ps, achieving 59 nM ·OH detection via ratiometric sensing and enabling dual‐channel ·OH monitoring in onion cells.

Desymmetrization of Pseudo‐para Diformyl[2.2]Paracyclophane via Brønsted Acid‐Catalyzed Reductive Amination

Advanced Synthesis &Catalysis, Volume 368, Issue 9, 5 May 2026.
A highly stereoselective desymmetrization of pseudo‐para diformyl[2.2]paracyclophanes is developed via chiral Brønsted acid‐catalyzed reductive amination. This protocol provides efficient access to enantiopure planar chiral paracyclophanes with broad substrate scope, excellent enantioselectivity, and versatile postsynthetic functionalization. Access to

Highly Lewis Acidic In Situ‐Generated Boronic Acid Ester: A Practical Catalyst for Hosomi–Sakurai Conjugate Addition, Carbonyl‐Ene Reaction, and Silane‐Mediated Amide Reduction

Advanced Synthesis &Catalysis, Volume 368, Issue 9, 5 May 2026.
An exceptionally Lewis acidic boronic acid ester, generated in situ from pentafluorophenylboronic acid and tetrabromonaphthalenediol, catalyzes three important chemical transformations at 1–10 mol% loading: the Hosomi–Sakurai allylation of α,β‐unsaturated ketones, intermolecular carbonyl‐ene reactions, and the reductions of tertiary amides to amines ...

Highly Stable and Minimally Pt‐Loaded Multiporous Bimetallic Matryoshka Heterostructures for Efficient Hydrogen Evolution Reaction via pH‐Dependent Mechanistic Decoupling

Advanced Synthesis &Catalysis, Volume 368, Issue 9, 5 May 2026.
Highly uniform, multi‐porous Au–Pt Matryoshka heterostructures were synthesized via a facile galvanic replacement reaction using Au@Ag coreshells as sacrificial templates. By precisely tuning the Au/Pt composition, the catalysts were optimized for the hydrogen evolution reaction (HER), exhibiting outstanding efficiency and ultra‐high stability in both ...

Synthesis of a π‐Extended Phenazine Diimide Derivative and Characterization of Its Closed‐Shell Reduced States

Chemistry – A European Journal, Volume 32, Issue 17, 5 May 2026.
In this work, the synthesis and characterization of novel π‐extended phenazine diimides is reported. The derivatives undergo differential reduction to a dihydrophenazine or Meisenheimer form depending on the reaction conditions employed. The outcome of this work highlights the paramount importance of structural design in determining the nature of the ...
