Conducting polymers (CPs) are highly conjugated organic macromolecules, where the electrical charge is transported in intra- and inter-chain pathways. Polyacetylene, polythiophene its derivatives, polypyrrole polyaniline among best-known examples. These compounds have been used as electrode modifiers to gain sensitivity selectivity a large variety of analytical applications. This review, after ...

Polymer electrolyte membrane fuel cells (PEMFC) fed with H2 contaminated with CO may exhibit oscillatory behavior when operated galvanostatically. The self-organization of the anodic overpotential is interesting because it can be accompanied by an increase in the average performance. Herein we report experimental studies of voltage oscillations that emerge in a PEMFC equipped with a Pd/C or PdP...

Copper was electrodeposited onto nand p-type GaAs~001! from mMol solutions of CuSO4 in 0.5 Mol sulfuric acid and the registration of the Cu adsorbate was analyzed with respect to the GaAs lattice in situ with x-ray standing waves, recording the Cu-Ka fluorescence radiation from the sample surface while scanning the GaAs~004! Bragg reflection. For coverages below 1 ML, the determined coherent po...
