A stable Zn metal electrode can develop rechargeable zinc batteries (RZMBs) which have the high theoretical capacity (820 mAh g ?1 ), low redox potential, and intrinsic safety. However, corrosion of in aqueous electrolytes dendrite formation during plating process lead to poor cycling thus hinder development RZMBs. Here, we employed ionic liquid-based gel polymer (poly(vinylidene fluoride)-co-h...

Waste incineration fly ash was successfully recycled to calcium phosphate hydrogel, a type of fast proton conductor. The crystallized hydrogel from incineration fly ash had a lower electric conductivity and a lower crystallinity than that from calcium carbonate reagent. However, the difference in electric conductivity between these crystallized hydrogels decreases with temperature. This was due...

Potentiometric membrane electrodes that respond to heparin and other polyanions were introduced in the early 1990s. Herein, the mechanism of polymer membrane electrode type heparin sensors is revisited. The extraction/diffusion of heparin is studied via both potentiometric and impedance spectroscopic techniques using a pre-fractionated heparin preparation that contains polyanionic species > 100...

A bis(terpyridine)iron network polymer was fabricated by electropolymerisation on a glassy carbon electrode. The modified electrode allowed high-speed charging and discharging with a minor capacity decay (only 5% after 3000 cycles at 1 V s(-1)).

Enzyme sensor for organophosphorus insecticides organophosphorus hydrolase in a polymer membrane on a pH sensor is used to catalyse the hydrolysis of compounds with phoshate ester functionality. The detected [H+] change is proportional to the concentration of the phosphate ester insecticide. This is a good example of the use of an enzyme to give selectivity to a specific class of compounds. Unf...

Cytochrome c (cyt c)-immobilized monolayers and multiple monolayers of a conducting polymer [poly(terthiophene-3-carboxylic acid) polymer (poly-TTCA)] were prepared, where the monolayer of monomer precursor was fabricated with the Langmuir-Blogett technique. Covalent immobilization of cyt c was achieved by the formation of an amide bond between the carboxylic groups of the conducting polymer an...

Ion-selective electrode (ISE) based potentiometric gas sensors have shown to be promising analytical tools for detection of chemical vapors. However, such sensors are only capable of detecting those vapors which can be converted into ionic species in solution. This paper describes for the first time a polymer membrane ISE based potentiometric sensing system for sensitive and selective determina...

An all-solid-state fluoride ion-selective electrode (ISE) was prepared using LaF3 single crystal with poly(3,4-ethylenedioxythiophene (PEDOT) as the solid contact layer. In contrast to polymer-based ISEs, crystalline membrane-based ISEs have not been used for device, thereby prohibiting integration of on a chip. The ISE developed in this study exhibited superior sensitivity (−56.0±0.9 mV/dec) a...
