Bimetallic Bismuth‐Based Nanoparticles From Pseudo‐Tetrahedral Zintl Anions

open access: yesSmall, Volume 22, Issue 28, 18 May 2026.
Bismuth‐based Zintl anions are explored as precursors for synthesizing bimetallic nanoparticles with tunable compositions and morphologies, including alloyed, core–shell, and Janus types. The resulting nanoparticles display composition‐dependent UV absorption.

Chemical Upcycling of Nitrile Butadiene Rubbers to Polyamines and Polyols by Chemoselective Catalytic Hydrogenation

open access: yesAngewandte Chemie, Volume 138, Issue 18, 27 April 2026.
We demonstrate here the transformation of NBR (Nitrile butadiene rubber) including post‐consumer waste sourced from nitrile gloves and o‐rings into polyamines and polyols via ruthenium catalyzed hydrogenation. ABSTRACT We report here two new approaches for the chemical recycling/upcycling of nitrile butadiene rubber (NBR) to make either polyamines or ...

Ecotoxicological Evaluation of Organic Sunscreens Used Worldwide, Alone and in Mixture, on Terrestrial Plants

open access: yesEnvironmental Toxicology, Volume 41, Issue 5, Page 257-269, May 2026.
ABSTRACT The environmental hazards of sunscreens are discussed worldwide. However, there are few ecotoxicological studies on these compounds alone for edaphic organisms, and none for their mixtures. Avobenzone (1 and 10 ng/L), octocrylene (10 and 100 μg/L), and oxybenzone (2 and 20 μg/L), alone and in binary combinations (between the lowest and the ...

In Vivo Measurement of UVA Protection Factor (ISO 24442:2011) Across 38 Different SPF 50 and SPF 50+ Sunscreens Reveals High Heterogeneity and Limitations in the Level of Protection

open access: yesPhotodermatology, Photoimmunology &Photomedicine, Volume 42, Issue 3, May 2026.
ABSTRACT Background/Purpose The UVB and UVA components of terrestrial solar ultraviolet radiation (UVR) cause acute and chronic damage to skin. These adverse effects can be reduced by sunscreen application. The sun protection factor (SPF) is primarily a measure of UVB protection against erythema and does not quantify protection from UVA, which is the ...

Fungal Pathogen Activity and Stress‐Dependent Responses of Grapevine Wood to Esca and Drought

open access: yesPhysiologia Plantarum, Volume 178, Issue 3, May/June 2026.
ABSTRACT Biotic and abiotic stresses alter the physiology of perennial plants, with consequences for fungal endophytes and disease expression. In grapevine, drought inhibits esca disease expression, but the underlying molecular interactions between the plant and fungi are unknown. We combined wood metatranscriptomics, metabolomics, and metabarcoding to
