Resolving the biome debate: ecological and palaeo‐data concur that the extensive tree‐limited grassy biomes of central and north‐western Madagascar are largely anthropogenic

Biological Reviews, EarlyView.
ABSTRACT For millennia, human activities have transformed ecosystems globally. Determining which landscapes are predominantly anthropogenic is crucial to conservation and habitat restoration. Madagascar, a critically‐threatened biodiversity hotspot, is a prominent example.

Carbon‐Embedded Fe‐Cu Composite Oxide Nanoparticles Derived From Spindle‐Shaped Bimetallic MOFs for Selective Oxidation of Methane

Carbon and Hydrogen, EarlyView.
Fe3Cu1/C (CuFe5O8) was synthesized by high‐temperature carbonization of FexCuyBDC MOF, which exhibited excellent catalytic performance for methane selective oxidation at 80°C. The synergistic effect between Cu and Fe in the derived Fe3Cu1/C (CuFe5O8) composite oxide inhibits deep oxidation compare to Fe/C (Fe3O4), and the reaction proceeds via a free ...

Dual‐Function Electrocatalysis: Simultaneous Wastewater Remediation and Hydrogen Evolution—A Comprehensive Review

Carbon Energy, EarlyView.
Replacing the oxygen evolution reaction with the electro‐oxidation of pollutants and waste streams offers an energy‐efficient route for simultaneous hydrogen production and pollutant remediation. This review summarizes the reaction mechanisms, catalyst design principles, and emerging paired‐electrolysis strategies that govern activity, selectivity ...

The Impact of Glycation on Protein Digestibility

ChemFoodChem, EarlyView.
Schematic overview of how protein glycation affects digestibility and downstream nutritional consequences. Glycation‐derived structural modifications reduce protease accessibility, leading to limited hydrolysis and altered peptide generation. These changes decrease amino acid bioavailability and may subsequently contribute to microbiome alterations ...
