WebTwo major challenges, namely, hydroxide conductivity and alkaline stability of the polymer membrane, are yet to be resolved adequately in spite of significant research outcomes on alkaline anion exchange membrane (AAEM) in the recent past. To address these challenges, in this work, the development of ionically cross-linked AAEMs has been achieved by … WebApr 11, 2024 · In the present study, polysaccharide-based cryogels demonstrate their potential to mimic a synthetic extracellular matrix. Alginate-based cryogel composites with different gum arabic ratios were synthesized by an external ionic cross-linking protocol, and the interaction between the anionic polysaccharides was investigated. The structural …
Web3.5.2 Hyaluronic acid. Hyaluronic acid is a natural polyanion present in all living organisms. Of course, this linear polysaccharide is produced by bacterial zymosis and is subsequently improved. First, hyaluronic acid exists in the extracellular and pericellular matrix, but it is also available intracellularly. WebAug 10, 2024 · As a potential solution to ubiquitous energy concerns, anion-exchange membranes (AEMs) have been widely used as the electrolyte in alkaline fuel cells (AFCs), and significant refinement of AEMs has been achieved in the past few decades. However, it remains unknown whether AEMs can be used as an electrolyte in a solid-state …
Polyelectrolytes that bear both cationic and anionic repeat groups are called polyampholytes. The competition between the acid-base equilibria of these groups leads to additional complications in their physical behavior. These polymers usually only dissolve when there is sufficient added salt, which screens the interactions between oppositely charged segments. In case of amphoteric macroporous hydrogels action of concentrated salt solution does not lead to dissolution of poly… WebSpirobiindane-Based Poly(arylene ether sulfone) Ionomers for Alkaline Anion Exchange Membrane Fuel Cells. / Choi, Jieun; Jang, Jue Hyuk; Chae, Ji Eon et al.
