Development of Vertical Wind Turbine Blades Using 4D Printing of Composites

open access: yesPolymer Composites, Volume 47, Issue 12, Page 10966-10975, 20 June 2026.
Vertical axis wind turbine: White blade: Commercial. Black blade: Composite. ABSTRACT This paper presents the procedure to make vertical wind turbine blades using the technique of 4D printing of composites (4DPC). The blades are made using carbon/epoxy composite materials with a fiber volume fraction of about 60%.

CO2‐Activated Starch‐Derived Hierarchically Porous Carbon for High‐Performance Zinc‐Ion Hybrid Supercapacitors

open access: yesChemSusChem, Volume 19, Issue 11, 15 June 2026.
High‐performing materials are required to achieve efficient energy storage; however, their environmental benefits can be undermined if toxic/corrosive chemicals, or high water usage, are required for their preparation. We present an environmentally friendly route to hierarchical porous carbon from starch, using carbon dioxide (CO2) as a mild activating
