The effects of ionic analytes on the electrochemical properties of quaternary ammonium binaphthyl salts are described in this work. The stability of the binaphthyl radicals and hence the reversibility of the electrochemical response are discussed in terms of molecular structure. The ability of azacrown derivatised binaphthyl salts to act as amperometric receptors is ascribed to the strain impar...

The ability to bridge ionic and electronic transport coupled with large volumetric capacitance renders organic electrochemical transistors (OECTs) ideal candidates for bioelectronic applications. Adopting ionic-liquid-based solid electrolytes extends their applicability facilitates large-area printable productions. However, OETCs employing tend show a pronounced hysteresis in the transfer curve...

Abstract Electrochemical alongside the electro-catalytic properties of graphene and multi-walled carbon nanotubes have been improved via doping with manganese oxide nanostructures. Structural, morphological, electrochemical as-synthesized nanocomposites were identified using XRD, FTIR, SEM, methods including cyclic voltammetry, impedance spectroscopy. The SEM images showed flower-like microsphe...

The synthesis, structural, thermal and electrochemical properties of fluorine-free silver-containing ionic liquids are presented. The ionic liquid cations are formed by a silver(i) ion surrounded by two 1-alkylimidazole ligands, with the counter anions being nitrate ions. Depending on the alkyl chain length, the complexes were found to be liquids at room temperature or melting slightly above th...

porous silicon samples were prepared by electrochemical etching method for different etching times. the structural properties of porous silicon (ps) samples were determined from the atomic force microscopy (afm) measurements. the surface mean root square roughness (σ rms) changes as function of porosity were studied, and the influence of etching time on porosity and roughness was studied too. u...

nanostructured alumina thin films were coated on stainless steel by sol-gel dip coating method. in order to prevent crack formation, al2o3 films were kept in a solvent bath immediately after coating to reduce the rate of drying. effects of calcination temperature and withdrawal speed on structural properties were analyzed using xrd and sem. topography and thickness of coatings were analyzed by ...

The effect degradation in-service and in-laboratory conditions of the low-alloyed steels and aircraft aluminum alloys on its electrochemical conditions has been investigated. It is shown that the structural changes over degradation causes not only material embitterment, but also an activation of anodic and cathode electrode reactions and, correspondingly, a decrease of corrosion resistance. Suc...
