Microwave‐Assisted One‐Pot Synthesis of Alkyl Levulinates From Post‐Harvest Vegetable Waste
Advanced Sustainable Systems, EarlyView.Vegetable waste is valorized through Soxhlet extraction using H₂O₂ and heteropolyacid (HPA), followed by material characterization (XRD, FTIR, TGA, DSC). A microwave‐assisted reaction at 170 °C for 30 min with HPA and alcohol yields bio‐based esters.

Glutathione Threshold‐Triggered Selective Breakability of Organosilica Nanocapsules
ChemCatChem, EarlyView.Replacing tetraethoxy orthosilicate (TEOS) by tetramethoxy orthosilicate (TMOS) as silica precursor to synthesize cleavable organosilica nanocapsules enabled the effective and selective entrapment of a positively charged protein as Cytochrome C (CytC) and a much more favorable breakability and kinetics release when exposed to high glutathione (GSH ...
