ChemSusChem, Volume 18, Issue 18, September 23, 2025.A sustainable valorization of chestnut wood waste is proposed through microwave‐assisted subcritical water extraction, optimized via central composite design. The extract is fractionated by membrane filtration and resin purification, enabling water recovery (up to 89%) and obtaining a tannin‐rich fraction, used to synthesize a PVA‐based biopolymer ...

Meteoritics &Planetary Science, Volume 60, Issue 7, Page 1573-1586, July 2025.Abstract Dissociated zircon is largely used as a robust indicator of glasses generated by impact cratering and airbursts. The reaction of zircon dissociation, i.e. ‘ZrSiO4 → ZrO2 + SiO2’, requires high temperatures (>1670°C) only reached by extreme geological processes. Using high‐temperature experiments, this study shows that zircon can dissociate and

One‐Pot Microwave‐Assisted Olefin Hydroaminomethylation Over Bifunctional Heterogeneous Rh Catalysts
ChemCatChem, Volume 17, Issue 12, June 23, 2025.Heterogeneous lab‐made Rh/CNFs gave yield >99% in the one‐pot MW‐assisted hydroaminomethylation of olefins to amines, using EtOAc as the solvent, due to the synergy between metal and acid surface sites. Acetic acid addition promoted both conversion and selectivity during the rate‐determining hydroformylation step.
