The development of ion-solvating membranes with low ion resistance and high ion selectivity remains a challenge in the field of electrochemical energy conversion and storage. Here the authors report that watermelon skin ion-solvating membrane exhibits high ion conductivity and high ion selectivity. ...
the catalyst. Thus the process of physisorption results in the H2molecule remaining intact. And, in opposite, chemisorption leads to H2bond dissociation, with the resulting H atoms forming chemical bonds with the storage substrate [49]. Physisorption can occur as a preliminary state to chemisorption...
Energy Storage Performances of Polymer-DG blends We summarized the energy storage performances of FPI-DG blends at high temperatures (150 °C and 200 °C) according to their electric displacement-electric field (D-E) loops as shown in Fig.3A, B, and FigureS28&S29. As seen, DG remarka...
release of an electron and a water molecule (Step II, Eq.3). Thereafter, the nucleophilic attack of OH−on *O yields the intermediate *OOH (Step III, Eq.4). Finally, a further proton-coupled-electron transfer process results in the generation of one oxygen molecule as well as a free ...
Nowadays, solar energy is the most environmentally friendly energy source to drive many chemical reactions and physical processes. However, the corresponding fabrication procedures for obtaining excellent energy-storage devices are relatively complicated

Another point is the very small size of dihydrogen molecule (the H-H bond is 74.14 pm), dihydrogen can escape through materials by permeation but also damage it (hydrogen embrittlement). 4. Hydrogen Storage The hydrogen storage technology is a multidisciplinary research and development field. It ...
