Corrigendum to Evaluation of radiation stability of electron beam irradiated Nafion® and sulfonated poly(ether ether ketone) membranes
Pajuste, Elina; Reinholds, I.; Vaivars, Guntars; Antuzevics, Andris; Avotiņa, L.; Sprūģis, Einārs; Mikko, R.; Heikki, K.; Meri, R.M.; Kaparkalējs, Reinis (Elsevier, 2022)Proton exchange membranes (PEM), which have been commonly used in fuel cells have raised interest for the application in harsh environments involving ionizing radiation. Therefore, radiation stability and ability to sustain ... -
Critical Evaluation of the Methods for the Characterization of the Degree of Sulfonation for Electron Beam Irradiated and Non-Irradiated Sulfonated Poly(ether ether ketone) Membranes
Pakalniete, Laura Dace; Maskova, Elizabete; Zabolockis, Rudolfs Janis; Avotina, Liga; Sprugis, Einars; Reinholds, Ingars; Rzepna, Magdalena; Vaivars, Guntars; Pajuste, Elina (MDPI, 2023)Sulfonated poly(ether ether ketone) (SPEEK) materials are promising candidates for replacing Nafion™ in applications such as proton exchange membrane (PEM) and direct methanol fuel cells. SPEEK membranes have several ... -
