Green Extraction and Fractionation of Chestnut Wood Waste: A Sustainable Pathway to Biopolymers and Antimicrobial Solutions

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 ...

Low‐temperature dissociation of zircon in highly alkaline conditions: A cautionary note for studies on natural glasses of debated origin

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.

Rivalry as a Contextual Factor of Gender Inequality in Network Returns

Journal of Management Studies, Volume 62, Issue 4, Page 1599-1643, June 2025.
Abstract Linking research on networks, rivalry, and gender, we develop a contextual approach to gender‐based differences in network returns. Our principal contribution is in articulating the role of rivalry – a personalized and relational form of competition – in influencing the cognitive activation and behavioural mobilization of social networks ...

Grape Stalks Valorization towards Circular Economy: A Cascade Biorefinery Strategy

ChemSusChem, Volume 18, Issue 10, May 19, 2025.
A cascade protocol for grape stalks valorization has been proposed, characterized by a multidisciplinary strategy using unconventional techniques and subcritical water as a green solvent, where physical/chemical treatments synergistically interact with biological treatments to obtain added value products from all the biomass components.
