1-(6-bromohexyl)-3-methyl-2-(2,4,6-trimethylphenyl)-2H-benzimidazolium bromide was synthesised and grafted onto polybenzimidazole (PBI). The highest obtained degrees of functionalisation were 0.7 and 1.1 ionic groups per repeat unit, corresponding to

For development of anion exchange membrane (AEM) water electrolysis systems, a series of polymers was synthesised by reacting 2-mesityl-benzimidazole (BIM) and brominated poly-(2,6-dimethyl-1,4-phenylene oxide) (Br-PPO) in a Menshutkin reaction, and

A new cationic ionene was synthesised from dibromoxylene and 2-(2,4,6-trimethylphenyl)benzimidazole. Even though the weight average molecular weight Mw reached values around 40,000 g/mole, no membranes could be prepared from this ionene, probably bec

Felis catus gammaherpesvirus 1 (FcaGHV1), recently discovered in the USA, was detected in domestic cats in Australia (11.4%, 95% confidence interval 5.9–19.1, n=110) and Singapore (9.6%, 95% confidence interval 5.9–14.6, n=176) using qPCR. FcaGHV

Evaluation of the long-term stability of electrocatalysts is typically performed using galvanostatic polarization at a predefined current density. A stable or insignificant increase in the applied potential is usually interpreted as high long-term st

Water self-diffusion anisotropy in perfluorosulfonic acid (PFSA)/SiO2 composite membranes was investigated by pulsed gradient spin-echo NMR as a function of diffusion time, temperature and relative humidity. The anisotropy of water diffusion that is

We report on the preparation and characterization of perfluorosulfonic acid ionomer (PFSA) – silica composite membranes using hyperbranched polyethoxysiloxane (PEOS) as silica precursor. The membranes were formed via an in situ sol–gel process of

A diffusion-exchange model with the assumption of two water pools was applied to describe the water transport in perfluorinated sulfonic acid (PFSA)/SiO 2 nanocomposites. The water diffusivity in-plane and through-plane in solution cast films was mea

Poly(perfluorosulfonic acid)/silica (PFSA/SiO2) composites were investigated by 129Xe NMR spectroscopy and relaxometry. 129Xe chemical shift extrapolated to zero pressure was used for calculation of average free volume hole size. This quantity reache
