Abstract Proton-exchange membrane fuel cells demand efficient electrode–electrolyte interfaces to catalyse the oxygen reduction reaction (ORR), kinetics of which depends on energetics surface adsorption and electrolyte environment. Here we show an unanticipated effect non-specifically adsorbed anions ORR a Pt(111) electrode; these trends do not follow usual descriptor, that is *OH binding energ...

The purpose of this study was to evaluate the genotoxic potential of components leached from two conventional self-curing glass-ionomer cements (Fuji IX and Ketac Molar), and light-curing, resin modified glass-ionomer cements (Vitrebond, Fuji II LC). Evaluation was performed on human lymphocytes using alkaline and hOGG1 modified comet, and micronucleus assays. Each material, polymerised and unp...

Many choices are available to the practitioner of restorative dentistry for children. With the introduction of several new classes of restorative materials in recent years, some confusion has been created about what these materials are, making it difficult to identify their appropriate clinical use. This paper reviews glass-ionomer materials, resin-modified (reinforced) glass ionomers, compomer...

Highly durable anion-exchange membranes and ionomers are essential for developing cost-effective green hydrogen generation. The membrane ionomer must withstand chemical attacks by OH– ions as well nonlinear mechanical stress caused irregular bubble formation when the electrolyzer is coupled with intermittent power sources. Herein, we examined durability of a trimethylammonium-modified poly(fluo...

The applicability of time-temperature superposition of dynamic mechanical data for miscible polymer blends that exhibit strong intermolecular interactions was investigated. Blends of the lithium salt of lightly sulfonated polystyrene ionomers (Li-SPS), 9-12mol% sulfonation, and N-methylated nylon-2,lO (mPA) were miscible over the composition range studied, 30-70 wt% ionomer. Time-temperature su...
