Chiral‐Induced Spin Selectivity Effect in a 1 nm Thin 1,1′‐Binaphthyl‐2,2′‐diyl Hydrogenphosphate Self‐Assembled Monolayer on Nickel Oxide

Advanced Science, Volume 13, Issue 52, 18 September 2026.
A self‐assembled monolayer (≈0.9 nm) of an axially chiral binaphthol phosphoric acid derivative on a ferromagnetic Ni/NiOx substrate shows chiral‐induced spin selectivity (CISS) magnetoresistance of 50%–80%. This thermally and chemically robust functional stack shows the way towards practical spintronic devices based on the CISS effect.

Synthetic Food Colorants and Gut Microbiota: A Systematic Review of Preclinical Studies

Food Frontiers, Volume 7, Issue 5, September 2026.
ABSTRACT Growing evidence suggests that industrial food processing, including the excess consumption of food additives, might have a negative impact on human health. Despite regulatory safety evaluations, their impact on gut microbiota remains poorly characterized.

Anchoring Polyoxometalate (PMo11Fe) on ZnO Nanosheet for Construction of a Novel S‐Scheme Heterojunction Toward Efficient Photodegradation of Levofloxacin Antibiotics

Rare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT Currently, the photocatalytic performance of ZnO has been severely limited by its weak light response ability and sluggish charge carrier dynamics, which considerably hinder its extensive application in photocatalytic fields. Herein, through anchoring the synthesized K6PMo11FeO40·nH2O (PMo11Fe) onto ZnO nanosheets, a novel S‐scheme ...

Metal‐Catalyzed Intermolecular Cyclization Reaction of Diazonaphthoquinones With Glycidol Derivatives

ChemistrySelect, Volume 11, Issue 36, 22 September 2026.
The metal‐catalyzed cyclization reactions of diazonaphthoquinones with glycidol yielded naphthodioxane derivatives. In this reaction, the metal carbene, formed from the diazonaphthoquinone and metal catalyst (rhodium or palladium), initially reacts with the hydroxyl group of glycidol to produce an O─H insertion product.
