Poly(Hydroxybutyrate‐Co‐Hydroxyvalerate)/Thermoplastic Starch Blends for Application in Biodegradable Mulch Films

Polymer Engineering &Science, Volume 66, Issue 5, Page 3751-3765, May 2026.
Poly(hydroxybutyrate‐co‐hydroxyvalerate)/thermoplastic starch blends, produced by melt processing, showed improvements in mechanical properties and water vapor transmission barrier performance, which can help control excessive water evaporation from the soil, thus contributing to pH and moisture regulation.

Valorization of Garcinia humilis Residues in Active Collagen/Starch Films for Biodegradable Packaging Applications

Packaging Technology and Science, Volume 39, Issue 5, Page 517-531, May 2026.
Residues from Garcinia humilis were used to obtain a phenolic‐rich extract (GHRE) and incorporated into collagen–starch films. The addition of GHRE improved antioxidant activity, thermal stability and elasticity, while reducing water vapour permeability.

Exploring the Role of Activating Agents on the Electrocatalytic Activity of Grape Pomace‐Derived Catalysts for the Oxygen Reduction Reaction

Small Science, Volume 6, Issue 5, May 2026.
This work explores the influence of KOH (alkaline agent) and ZnCl2 (pore‐generating agent) on the one‐step chemical activation of wine grape pomace to produce Fe‐N‐C catalysts for the oxygen reduction reaction (ORR). The analyses reveal that KOH activation generates a highly porous structure with Fe‐Nx sites, leading to a larger electrochemically ...
