A Para‐Selective Kolbe–Schmitt Reaction

open access: yesAngewandte Chemie, Volume 138, Issue 4, 22 January 2026.
Discovered over 150 years ago, the Kolbe–Schmitt carboxylation has established itself as one of the most well‐known chemical reactions. However, the process often requires extreme pressures and high temperatures. Here, we present a unique para‐selective Kolbe–Schmitt‐type carboxylation that proceeds at relatively low temperatures and uses near ...

Hidden Partners in Diversity: Acidobacteriota and Their Distribution in the Cape Floristic Region

open access: yesMicrobiologyOpen, Volume 15, Issue 1, February 2026.
Acidobacteriota diversity and abundance investigated in nutrient‐poor fynbos soils of the Cape Floristic Region. Nanopore 16S rRNA sequencing of 26 soil samples from Jonkershoek and Kogelberg identified dominant and rare subdivisions, revealed distinct community compositions, and demonstrated correlations between subdivisions and soil properties ...

The Redox Properties of Polyphenols and Their Role in ROS Generation for Biomedical Applications

open access: yesAngewandte Chemie, Volume 138, Issue 3, 16 January 2026.
The dual redox nature of polyphenols enables antioxidant activity and controlled reactive oxygen species (ROS) generation. This review details the biomedical applications of polyphenols in materials such as nanoparticles, coatings, and hydrogels for antimicrobial, tissue regeneration, and cancer therapies.

Food additives and children's behaviour: evidence based policy at the margins of certainty

open access: yes, 2009
The possible effects of food additives (specifically artificial colours) have been debated for over 30 years. The evidence accumulated suggests that for some children with attention deficit hyperactivity disorder (ADHD) food colours exacerbate their ...

Efficacy, Safety and Biological Characteristics of Formulation Based on Essential Oil Against Co‐Infections of Herpes Simplex Virus‐1 and Candida albicans

open access: yesMicrobiologyOpen, Volume 15, Issue 1, February 2026.
Essential oils with anti‐HSV‐1 activity were identified through literature review and tested against Candida to develop a formulation for co‐infections. The blend was assessed for anti‐inflammatory properties, allergenic potential via standardized BAT, and overall antiviral efficacy.
