Abstract Sulfonated poly(oxy‐1,4‐phenylene‐oxy‐1,4‐phenylenecarbonyl‐1,4‐phenylene) also known as SPEEK is a chemically robust cation conductor with good solution processability. A thin film (approx. 0.7 μm) coated asymmetrically over

Generator–collector electroanalysis approaching the nanomolar level is demonstrated for the reduction of Ru(NH 3 ) 6 3+ in aqueous (NH 4 ) 2 SO 4 (saturated, as a naturally low-oxygen electrolyte medium) and at tin-doped indium oxide (ITO) electrod

“Ionic diode” (or current rectification) effects are potentially important for a range of applications including water purification. In this preliminary report, we observe novel ionic diode behaviour of thin (300 nm) membranes based on a polymer
