Comprehensive Review of Synthesis, Structure, and Electrochemical Performance of LiFePO4
Advanced Science, EarlyView.Olivine‐structured LiFePO4 (LFP) nanomaterials are the most effective cathode materials for lithium‐ion battery applications. Here, we report how precursor chemistry, synthesis routes, morphology control, carbon engineering, and doping strategies govern phase formation, charge transport, and electrochemical behaviour of LFP cathodes.

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 ...
