Characterizing Biopolymer Electrolytes in Zinc–Air Batteries: Challenges, Best Practices, and a Robust Workflow Guiding Future Research Paths

open access: yesAdvanced Energy Materials, EarlyView.
Bio‐based gel polymer electrolytes promise sustainable, mechanically adaptable zinc–air batteries, yet their progress is constrained by inconsistent characterization. This review critically links formulation, structure, interfaces, and cell performance, identifies methodological gaps under alkaline operating conditions, and proposes application ...

Seaweed Polysaccharides and Derived Oligosaccharides Stimulate Defense Responses and Protection Against Pathogens in Plants

open access: yesMarine Drugs, 2011
Plants interact with the environment by sensing “non-self” molecules called elicitors derived from pathogens or other sources. These molecules bind to specific receptors located in the plasma membrane and trigger defense responses leading to protection ...

Interactions of delivery systems modulating the digestibility of plant‐based proteins

open access: yesFood Biomacromolecules, EarlyView.
Abstract Plant‐based proteins are gaining interest as sustainable alternatives to animal‐derived proteins, but their digestibility is often lower and strongly influenced by protein structure, processing history, and food‐matrix interactions. This review critically examines how emulsions, hydrogels, micro‐ and nanoparticles, micelles, liposomes ...
