Solvent-free all-solid-state supercapacitors have recently received attention. Despite their highly specific capacitance, they suffer issues related to the solid–solid interface that degrade performance during prolonged cycling. Here, we propose a novel strategy for improving electrode–electrolyte by introducing small amount of polymer into activated carbon-based electrode. An electrode composi...

the overall goal of this study was to identify the appropriate biomaterials able to facilitate the regeneration in rat's injured adult spinal cord. acute damage to axons is manifested as a breach in their membranes, ionexchange distortion across the compromised region, local depolarization and even conduction block. it would be of particular importance to interrupt the progress of events h...

A thiocyanate poly(vinyl chloride) (PVC) membrane electrode based on [1,2-bis(diphenylphosphino)ethane]dihalopalladium(II), [(dppe)PdX2, X = Cl (L), X = I (L)] as active sensor has been developed. The diiodopalladium complex, [(dppe)PdI2](L) displays an anti-Hofmeister selectivity sequence: SCN‒ > I‒ > ClO4‒ > Sal‒ > Br‒ > NO2‒ > HPO4‒ > AcO‒ > NO3‒ > H2PO4‒ > CO32‒. The electrode exhibits a Ne...

a pvc membrane electrode based on 1-[({[(butylsulfunyl)carbothioyl]disulfanyl} carbothioyl)sulfanyl]butane as a suitable ion carrier for determination of lanthanum(iii) ion was prepared. this electrode revealedsuch a good selectivity toward la3+ ion over a wide variety of other metal ions. some experimental parametersuch as membrane composition, nature, and amount of plasticizer, the amount of ...

Cyclic voltammetry (CV), synchrotron radiation-X-ray photoelectron spectroscopy (SR-XPS) and near edge X-ray absorption fine structure (NEXAFS) show that oxidation of ferrocene tagged PVC induces an accumulation of high molecular weight polymer at the buried interface between the substrate electrode and the plasticized membrane.

A layer-by-layer assembled and molecular-complexed polymer membrane was prepared by the simple combination of poly(4-styrenesulfonic acid) and poly(allylamine) on a comb-shaped gold electrode: it displayed a very high proton conductivity of 10(-3) S cm(-1) under a dry condition at 120 degrees C.

a new cesium ion selective pvc membrane based on parent calix [4] arene was developed for potentiometric determination of cesium in environmental samples. the electrode based on p-5,11,17,23tetra(tertbutyl) 25,26,27,28-tetrahydroxy calix[4]arene(thc) as ionophor ,dibutyl phthalate (dbp)as plasticizer ,sodium tetra phenyl borate(natpb)and oleic acid as lipophilic salt and additive showed the bes...

Ion-selective electrodes (ISEs) are widely used in clinical examinations. The mechanisms of ISEs have been studied to develop a disposable ISE for "dry chemistry" analyses. The behavior of Na+ and Ag+ in an ion-selective polymer liquid membrane (ISM) containing methyl monensin (MMO), which is selective for Na+, has been clarified by x-ray microanalysis and measurement of electrical potential. T...
