Methanogen‐Mediated Precipitation of Mn Carbonates at the Expense of Mn Oxides

Geophysical Research Letters
Whether Mn carbonates can be used as a proxy for the oxygenation event is debated. Here we examined the Early Cretaceous lacustrine Mn carbonates from North China, which contain abundant microbial fossils. The extremely positive δ13C (up to +15‰ relative

Temperature‐Dependent Kinetics of Plasma‐Based CO2 Conversion: Interplay of Electron‐Driven and Thermal‐Driven Chemistry

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
The transformation of CO2 into chemical building blocks is essential for a net‐zero energy future. Plasma‐chemical processing offers promising potential to achieve this. Here, we explore a temperature‐dependent plasma‐chemical reaction mechanism, revealing a shift from electron‐driven to thermal‐driven CO2 conversion regimes.

Bio‐based tannin‐loaded layered double hydroxides in epoxy coatings for smart corrosion protection of steel in underground infrastructure

Deep Underground Science and Engineering, EarlyView.
This study presents a sustainable smart‐coating strategy for protecting underground steel infrastructures from chloride‐induced corrosion. Zinc‐aluminum layered double hydroxides (LDHs) and tannin‐loaded LDHs (LDH–TA) were incorporated into an epoxy matrix to provide both enhanced barrier properties and active, pH‐responsive inhibition.

Stabilization Strategies for Catechins and Epicatechins: Recent Advances

Food Chemistry International, EarlyView.
Oxidation, epimerization, polymerization, and hydrolysis, driven by heat, pH, and oxygen, are pathways. Nano‐/microencapsulation maintains integrity with 70%–95% efficiency; biopolymer nanoparticles, starch/polysaccharide nanocarriers improve stability and dispersion. Lipid nanocarriers enhance bioavailability but raise oxidation risk.
