Flipping the Card With Enantiodivergent Organocatalysis
Chemistry – 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
Advanced 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.

Aggregate, 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 ...

Indian journal of medical sciences, 1992 Alpha and beta naphthols, the metabolites of naphthalene, a cataractogenic agent, was tested for it's effect on sheep lens proteases and their inhibitors. It reduced protease activities, not that of inhibitor activities of lens proteins. It also increased the efflux of free amino acid from lenses which was retarded by a high concentration of tissue ...

Food 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 ...

Food Science &Nutrition, Volume 14, Issue 8, August 2026.Parsley (Petroselinum crispum) was harvested at four ontogenetic stages (Pet‐1 to Pet‐4; May–September) under Mediterranean field conditions. Harvest timing significantly affected both agronomic yield and essential oil (EO) composition. Biomass yield peaked at Pet‐4 (10,076 kg da−1); EO content was highest at Pet‐2 (0.70%). GC–MS identified 55 volatile

Journal of Biomedical Materials Research Part A, Volume 114, Issue 8, August 2026.ABSTRACT Nanostructured titanium (Ti) facilitates osteoblast differentiation by modulating various signaling pathways and may enhance osseointegration, potentially through its influence on the formation and remodeling of the extracellular matrix (ECM). This study aimed to investigate the impact of osteoblast‐ECM‐functionalized nanostructured Ti surface

Photochromic carbazole photoinitiators for precision visible‐light photopolymerization
Polymer International, Volume 75, Issue 8, Page 722-728, August 2026.New carbazole–naphthopyran derivatives were employed as visible‐light‐activated photoinitiators, enabling rapid and localized radical photopolymerization to produce well‐defined thin solid objects within minutes. Abstract Two carbazole derivatives, each incorporating a naphthopyran unit and an aromatic ketone, were synthesized and evaluated as ...
