And the article was included in ACS Applied Energy Materials in 2022.Name: 1-Bromopyrrolidine-2,5-dione This article mentions the following:
A series of rPES(x/y)-MI membranes with different rigid side chains and high-d. imidazole cationic groups have been prepared for anion-exchange membrane (AEM) fuel cells (AEMFC). These AEM rPES(x/y)-MIs with IEC values of 1.91-2.31 mequiv g-1 exhibit high conductivities of 92.92-142.69 mS cm-1 at 80 °C, acceptable water uptake, and dimensional change. D. functional theory (DFT) was used to demonstrate the excellent alkali stability of this class of copolymers, which is consistent with exptl. results. In addition, the degradation mechanism of this type of AEM has also been investigated. Significantly, rPES(1/4)-MI-based AEMFC has the maximum power d. of 195 mW cm-2 at a c.d. of 525 mA cm-2, which is much higher than com. reference membrane FAS-30 measured in the same environment. In the experiment, the researchers used many compounds, for example, 1-Bromopyrrolidine-2,5-dione (cas: 128-08-5Name: 1-Bromopyrrolidine-2,5-dione).
1-Bromopyrrolidine-2,5-dione (cas: 128-08-5) belongs to organobromine compounds. Most of the natural organobromine compounds are produced by marine organisms, and several brominated metabolites with antibacterial, antitumor, antiviral, and antifungal activity have been isolated from seaweed, sponges, corals, molluscs, and others. In the pharmaceutical industry organo bromine derivatives are used as sedatives, vasodilators, antiseptic agents, and anticancer agents.Name: 1-Bromopyrrolidine-2,5-dione
