One‐Pot Depolymerization, Demethylation, and Phenolation of Lignin for Bioactive Polyphenol Production

open access: yesChemSusChem, Volume 19, Issue 13, 14 July 2026.
Low‐cost lignin was upgraded in an acidic lithium bromide (LiBr) solution via integrated depolymerization, demethylation, and phenolation to yield bioactive polyphenols with enhanced phenolic hydroxyl content. The resulting polyphenols exhibited strong antioxidant and antibacterial activities, along with low cytotoxicity and promising in vivo ...

Batteries From Reused, Recycled, and Surplus Materials

open access: yesAdvanced Sustainable Systems, Volume 10, Issue 7, July 2026.
Batteries can become more circular by combining reuse, direct recycling, metallurgical recovery, and material sourcing from industrial surplus streams. This Review highlights how recycled and waste‐derived metals, carbons, polymers, electrolytes, and active materials can be reintegrated into current and emerging batteries, while emphasizing design ...

Genetic variation in tree leaf chemistry predicts the abundance and activity of autotrophic soil microorganisms

open access: yesEcosphere, 2019
Genetic variation in the chemistry of plant leaves can have ecosystem‐level consequences. Here, we address the hypothesis that genetic variation in foliar condensed tannins along a Populus hybridization gradient influences soil ammonia oxidizers, a group
