The adsorption of chlorobenzene on the gold electrode
Electrochimica Acta, 1980Abstract The dependence of adsorption of chlorobenzene at the gold/electrolyte (0.5 M H 2 SO 4 ) interface on electrode potential, bulk concentration and temperature has been investigated using a 14 C-radiotracer technique. For higher bulk concentrations of chlorobenzene, multilayer adsorption has been observed.

Reduction of NAD^+ on a Gold Electrode
2005Nicotinamide adenine dinucleotide NAD(H) is a cofactor that plays the role of electron and hydrogen shuttle in most of the biochemical reactions catalyzed by redox enzymes (dehydrogenases or oxidoreductases). In its reduced and enzymatically active form (1, 4-NADH), the molecule transfers two electrons and a proton to a substrate in the presence of a ...

Modulation resistometry of a gold electrode
Russian Journal of Electrochemistry, 2000Electronic properties of metals are very important for electrochemical processes occurring at the metal/electrolyte interface [1]. One of the main parameters of solid metals reflecting their electronic structures is the conductivity or the electric resistance.

Nanostructured Gold Colloid Electrodes
Advanced Materials, 2000Recent advances in the assembly of nanoparticle superstructures on electrodesare addressed here. Methods for the assembly and characterization of these arrays are summarized and their electronic, photoelectrochemical, and sensor applications are discussed. The Figure shows a one-layer architecture of Au nanoparticles and tetracationic cyclophanes on an

Transparent gold nanowire electrodes
2011 11th IEEE International Conference on Nanotechnology, 2011Transparent electrodes are used to provide electrical contacts to the active layers of opto-electronic devices such as organic light emitting diodes, flat panel displays and solar cells. These electrodes should possess high optical transparency and low sheet resistance. Traditionally, tin doped indium oxide (ITO) is used for this purpose. Unfortunately,

Sol−Gel-Derived Gold Composite Electrodes
Analytical Chemistry, 1997The preparation, characterization, and analytical utility of sol-gel-derived gold composite electrodes is described. The new metal-ceramic electrodes are comprised of gold powder homogeneously dispersed in a modified silica matrix. They couple the favorable electron-transfer kinetics common to gold surfaces with the regeneration, bulk modification, and

Electrometric titrations with the gold electrode
Fresenius' Zeitschrift für analytische Chemie, 1958Massive gold because of the passivity of the oxide formed on its surface can be used as a substitute for platinum in electrometric titrations including acid-base and oxidation-reduction systems. The end points are attended with large jumps on the curves and coincide satisfactorily with those obtained using the hydrogen or platinum electrode or by other

Stark Spectroscopy of Tryptamine Immobilized on a Gold Electrode
Journal of Colloid and Interface Science, 1998Electroreflectance (ER), ellipsometry, and surface-enhanced Raman spectroscopy (SERS) measurements were performed for immobilized tryptamine on polycrystalline gold electrodes. SERS study indicates that the indole ring does not interact directly with the gold surface. Ellipsometric measurements yielded a thickness of the tryptamine layer of (1.98 +/- 0.
