Spouted bed drying parameters and adjuvant effects on polyphenol retention and antioxidant activity in mango peel powders

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Spouted bed drying of mango peels with colloidal SiO2 and corn starch produces a free‐flowing powder with reduced agglomeration, increased drying yield, and preserved antioxidant and polyphenol content. Abstract The production of polyphenol‐rich powders is a promising strategy for valorizing agro‐industrial byproducts. This study evaluated drying yield,

Crystallization of Cathode Active Material Precursors from Tartaric Acid Solution

open access: yesChemSusChem, Volume 18, Issue 6, March 15, 2025.
This work investigates a novel approach for closing the gap between recycling and production of lithium‐ion battery cathode material. The new concept is based on antisolvent crystallization of metal carboxylates, which can be directly used as precursors in production of cathode material.

Covalently Bonded S‐Scheme Polymer Heterojunction for Highly Efficient Solar Hydrogen Evolution

open access: yesEcoEnergy, EarlyView.
A covalently integrated all‐organic S‐scheme heterojunction (B‐CN2@Py‐CN) establishes atomic‐level charge transport channels and a strong built‐in electric field, enabling exceptional charge separation efficiency. This molecularly engineered photocatalyst achieves a cocatalyst‐free hydrogen evolution rate of 27.9 mmol g−1 h−1 under visible light ...
