A conventional colorimetric/fluorescent chemosensor R2PP was used to detect the Al3+ ion in CH3CN/DMSO (2:8, v/v) medium at nanomolar level (LOD = 8.5 × 10−9 M). The 2:1 binding stoichiometry of the metal complex was established on the basis of co

The perfluorosulfonic acid polymer membrane is most widely used in PEMFCs. However, its some major drawbacks like high cost and performance limitation at high temperature are obstacles of its commercialization. The goal of this study was to develop l

Sulfonic acid-based membrane gives the relatively high conductivity only in the presence of water, but phosphoric acid presents the relatively high proton conductivity without water because of its self dissociation natures to develop high temperature
