Background G protein-coupled receptor 40 (GPR40) is a key molecule in diabetes and fatty liver, but its role in endothelial dysfunction remains unclear. Our objective in this study was to determine whether GPR40 agonists protect endothelial cells aga

Cardo-poly(etherketone)-based anion-exchange membranes (AEMs) were prepared and employed as separators in a vanadium–cerium redox flow battery (V-Ce RFB). V-Ce RFBs with AEM separators yielded energy efficiencies (EEs) ranging from 67 to 84 % at cu

Cardo-polyethereketone (PEK-C) based anion exchange membrane (AEM) was prepared by quaternization using trimethylammonium. The structures of intermediates and AEMs were confirmed by NMR spectroscopy. The ion exchange capacity of the PEK-C AEMs was 1.

Cardo-polyetherketone (PEK-C) based anion exchange membranes (AEMs) were synthesized by chloromethylation of PEK-C followed by quaternization using trimethylamine (TMA). The ion exchange capacity (IEC) of the AEM was 1.4 ± 0.1 mmol g−1. The sulfat

Introduction Methanol crossover through the polymer electrolyte membrane is a key issue limiting the performance of DMFCs. This leads to depolarization and mixed potential as well as poisoning of the Pt catalyst, all of which reduce performance. To r
