Flipping the Card With Enantiodivergent Organocatalysis

open access: yesChemistry – A European Journal, Volume 32, Issue 29, 7 August 2026.
This minireview elaborates on recent organocatalytic strategies for achieving enantiodivergence—the ability to access both product enantiomers using a single chiral catalyst. It highlights how achiral stimuli, such as solvent polarity and chemical additives, along with minimal catalyst modifications, trigger stereochemical inversions in reactions ...

A Catalytic Osmium Redox Couple Collapses Cancer Redox Balance

open access: yesAdvanced Science, Volume 13, Issue 43, 3 August 2026.
A stable Os(III)/Os(IV) redox couple is developed to disrupt the tumor cell redox balance by concurrently catalyzing ROS generation and GSH depletion. Osmium‐treated cells exhibit multiple cell death pathways, including apoptosis, ferroptosis, and immunogenic cell death.

Helically Flexible Boron‐Dipyrromethenes for Solution‐Processed Isotropic Films With Preserved Chiral Exciton Coupling

open access: yesAggregate, Volume 7, Issue 8, August 2026.
Accessible and chiroptically tunable helically chiral boron‐dipyrromethene dimer dyes enable the fabrication of solution‐processed isotropic neat thin films that retain sharp visible electronic circular dichroism signatures from solution. This platform establishes a direct molecule‐to‐material relationship and provides a robust foundation for the ...

Interaction Among Microbiota, Chemical Composition, and Quality Variations in Coffea arabica Across Altitudinal Gradients During Wet Processing

open access: yesFood Science &Nutrition, Volume 14, Issue 8, August 2026.
Fermentation significantly altered the dominant bacterial genera from Sphingomonas and Pleomorphomonas (before fermentation) to Weissella and Lactobacillus (after fermentation), while Cladosporium and Fusarium remained the dominant fungal genera. Notably, non‐volatile compounds in de‐pulping coffee beans and volatile compounds of roasted coffee beans ...
