Ultra‐Tough Hybrid Supramolecular Gelatin Hydrogels

Small, Volume 22, Issue 61, 2 November 2026.
Tannic acid‐mediated coacervation compacts gelatin into a dense supramolecular network while generating an acidic microenvironment that activates pre‐embedded bis‐oxazoline crosslinkers. The resulting hybrid hydrogel combines covalent stabilization with reversible energy dissipation, producing high strength, extreme extensibility, substantial toughness,

Bioengineered Iron Nanoparticles From Canavalia cathartica Seeds: A Promising Nanobiosorbent for Cr (VI) Remediation

Chemistry &Biodiversity, Volume 23, Issue 10, October 2026.
Stable, core‐shell iron nanoparticles (FeNP‐CC) were green‐synthesized using Canavalia cathartica seeds rich in L‐canavanine, serving as the primary reductant and capping agent. Under optimal acidic conditions (pH 4.0), FeNP‐CC achieved 100% Cr(VI) removal within 50 min. This highly efficient remediation proceeds via sequential electrostatic attraction,
