Enhancing Stability of Layered Double Perovskites With a Naphthalene Diimide Spacer Toward Photoelectrochemical Application

Angewandte Chemie, EarlyView.
A bulky, hydrophobic naphthalene diimide dication spacer (NDI‐dH2+) endows the lead‐free layered double perovskite (NDI‐dH)2AgBiI8 with threefold‐higher in‐plane carrier mobility, an order‐of‐magnitude lower trap density, and exceptional water tolerance compared to aliphatic and benzene‐based analogues, enabling the first sustained photoelectrochemical

Interfacial Mn‐Carbon Nitride Synergy Enables Selective Photocatalytic C─H Chlorination via Single‐Atom Catalysis

Angewandte Chemie International Edition, EarlyView.
A manganese single‐atom photocatalyst on functionalised carbon nitride enables selective visible‐light‐driven C(sp2)─H chlorination. DFT‐supported mechanistic studies indicate that photoinduced charge separation activates NCS, while isolated Mn sites stabilize Mn─Cl intermediates at the catalyst interface.

A lumped modelling framework for the epoxidation of vegetable oils and fatty acid methyl esters

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Epoxidized vegetable oils and fatty acid methyl esters are promising bio‐based alternatives to phthalates for plasticizer applications. Their synthesis typically involves the reaction of unsaturated double bonds with peracetic acid in a biphasic liquid–liquid system, where the simultaneous occurrence of reaction and phase partitioning makes ...

Silence around SUDEP and its impact on caregivers of individuals with developmental and epileptic encephalopathies: An international survey

Epilepsia Open, EarlyView.
Abstract Objective Sudden Unexpected Death in Epilepsy (SUDEP) is the leading cause of epilepsy‐related mortality, particularly in individuals with Developmental and Epileptic Encephalopathies (DEEs). The goal of this work is to assess SUDEP‐related knowledge, information practices, emotional and psychological impact, and the use of preventive measures

EE2 and the Fish Brain: Age‐Dependent Impact of 17α‐Ethinylestradiol on Brain Cell Proliferation and Behavior in Sea Bass Larvae

Environmental Toxicology, EarlyView.
ABSTRACT Endocrine‐disrupting chemicals (EDCs), such as 17α‐ethinylestradiol (EE2), have raised concerns about their potential effects on aquatic organisms, particularly during early developmental stages. In this context, the study of behavioral disruption has gained considerable attention, as it may have consequences on individual fitness and ...

Impact of ultraviolet radiation‐induced damage to hair fiber integrity: A multi‐technique physicochemical characterization of surface and cortex properties

International Journal of Cosmetic Science, EarlyView.
UV exposure induces cuticular and cortical damage in natural hair, with oxidative effects and protein degradation comparable to bleaching. However, double bleaching leads to significantly greater structural degradation, emphasizing distinct mechanisms and severity of chemical versus UV‐induced damage. Abstract The combination of chemist techniques is a

Luminescence Vapochromism of a Cu(I)/Na Phosphane Iodide Assembly Based on a Secondary‐Sphere Sodium Response

Angewandte Chemie, Volume 138, Issue 44, 26 October 2026.
The luminescence of a heterometallic d‐s {Cu2I2Na2} phosphane‐phosphinate aggregate is regulated by an interplay of Na+–π/I– contacts and reversible coordination of oxygen‐containing organic molecules to Na ions. Structural variations caused by the incoming guest lead to a wide and selective variation of the emission color and illustrate a new approach
