High Value-Added Secondary Raw Material From Winemaking Waste Bentonite to Design Antioxidant Pectin-Based Mucoadhesive Buccal Films. [PDF]
ChemistryOpenHyaluronic acid and/or pectin (crosslinked by calcium lactate) allowed the development of Bentophen200 extract‐loaded buccal films. Given i) the antioxidant power of the polyphenols‐rich extract optimized via multiple maceration of waste bentonite and ii) the flexibility, mucoadhesivity, and suitability of the films for oromucosal application, they can

Porous Organic Cages for CO2 Capture and Confined Reduction
Angewandte Chemie, EarlyView.Porous organic cages (POCs) enable the coupling of CO2 capture and conversion through the interplay of molecular structure and solid‐state organization. Beyond intrinsic cavities, packing‐dependent pore accessibility and mass transport govern local CO2 concentration and catalytic performance, linking adsorption to reactivity in integrated capture ...
