Cross-linked PBI-based high-temperature membranes: stability, conductivity and fuel cell performance

Kerres, Jochen; Atanasov, Vladimir (Elsevier, 2015)

In this study different types of polybenzimidazole(PBI)-based High-T fuel cell membranes were investigated comparatively. The different membranes comprised: (1) ionically cross-linked PBI-excess blend membranes by mixing ...
Highly phosphonated polypentafluorostyrene: characterization and blends with polybenzimidazole

Atanasov, Vladimir; Kerres, Jochen; Gudat, Dietrich; Ruffmann, Bastian (Elsevier, 2013)

In this study we present results of the conductivity and resistance to thermooxidative and condensation reactions of a highly phosphonated poly(pentafluorostyrene) (PWN2010) and of its blends with poly(benzimidazole)s ...
Reactivity of Fe salts in the destabilization of acid mine drainage employing mixing and shaking techniques without pH adjustment

Ntwampe, I.O.; Waanders, F.B.; Bunt, J.R. (Elsevier, 2016)

Ferric chloride and Fe-sulphates are commonly Fe-salts used in water treatment, and the iron ionizes to form Fe3 + or Fe2 + when reduction occurs. A volume of 200 mL acid mine drainage (AMD) sample was poured into five 500 ...
