Investigations on volta potentials in water-nitrobenzene systems and on surface potentials of these solvents

Journal of Electroanalytical Chemistry and Interfacial Electrochemistry, 1983
Abstract The dynamic condenser method has been used for determination of Volta potentials in water-nitrobenzene partition systems, δ nw wn ψ (MX), as well as determining the difference between surface potentials Δ nw wn χ of both solvents. Values of Δ nw wn ψ o for several electrolytes have been measured and mutual consistency of these date ...

PHOTOINDUCED VOLTA POTENTIAL IN A PORPHYRIN MONOLAYER

Photochemistry and Photobiology, 1987
Abstract— When spread on an oxidizing aqueous subphase, an amphipathic basket handle zinc porphyrin (P) monolayer gives rise to a photoinduced Volta potential change. This surface photopotential is interpreted on the basis of an interfacial electron transfer in the interphase; upon light excitation, electrons are transferred from the chromophores in ...

Laser Effects on Volta Potential Transients Recorded by a Kelvin Probe

ECS Electrochemistry Letters, 2013
A laser beam focused beneath a Kelvin probe needle allows for evaluation of laser-induced Volta potential shifts that can be used to identify (ir)reversible structural rearrangements at the sample surface. This work investigates the impact of laser irradiation on different substrate materials and the influence of laser power and wavelength to explore ...

Volta potential analysis of intermetallics in 7A52 aluminum alloy

Journal of Wuhan University of Technology-Mater. Sci. Ed., 2012
In order to study the effect of intermaetallics on the corrosion behaviour of 7A52 aluminum alloy, the alloy was characterized by means of SEM-EDS and scanning Kelvin probe force microscopy(SKPFM). The experimental results indicate that there are two different intermetallics:Al-Mn-Fe and Mg2Si.

Volta potential at metal-solid salt interface and real potentials of ions in solid electrolytes

Journal of Electroanalytical Chemistry and Interfacial Electrochemistry, 1979
Abstract Experimental conditions and results of investigations of Volta potentials of metal-solidelectrolyte and solid electrolyte-aqueous electrolyte solution by means of the dynamic condenser method are presented. These investigations were made for silver-silver halides and silver-silver nitrate as well as for cadmium-cadmium halide systems. On the

Volta Potential on Stainless Steel Under Mechanical Stress Conditions

ECS Meeting Abstracts, 2014
It is well documented fact that mechanical work or surface treatment creates stresses in the metal. In corrosive environment the stress can lead to stress corrosion cracking and failure of the metal construction. It is often supposed that stress influences the properties of the surface oxide film by creating defects like metal vacancies and thus ...

The Story of the Volta Potential

1991
The discovery of galvanism by Luigi Galvani (1737–1798) and the series of further discoveries that almost immediately grew from that event, burst unexpectedly and dramatically on the intellectual world. It marked the beginning of the Age of Electricity and heralded the modern world.

The contact potential difference or Volta potential

1958
Sometime in 1801, Volta, who, together with Galvani, was responsible for the development of the galvanic cell, Voltaic pile, or, in short, the electrolytic cell, believed that there was an intrinsic potential difference between dry metals in no way related to the electrolytic phenomena occurring between metals in solutions.

Volta potentials in the water/1,2-dichloroethane and water /nitroethane systems

Journal of Electroanalytical Chemistry and Interfacial Electrochemistry, 1990
Abstract The Volta potentials of the water/1,2-dichloroethane and water/nitroethane interfaces in the presence of several salts were measured. The good consistency of these results made possible an estimation of the differences in the surface potentials of mutually saturated water/1,2-dichloroethane and water/nitroethane systems.
