Volta potential of clad AA2024 aluminium after exposure to CeCl3 solution
Corrosion Science, 2014Abstract AA2024 clad with AA1050 was immersed in CeCl 3 solution to promote deposition of cerium species. The deposition occurs on the entire sample surface for the alkaline etched substrate, while it is very limited for the degreased substrate. The surface potential (Volta potential) was investigated by scanning Kelvin probe force microscopy after ...

Volta-potential measurements characterizing the membrane properties of conducting polypyrrole films
Synthetic Metals, 1991Abstract The principle of Volta-potential measurements characterizing the membrane properties of pyrrole-based conducting polymer films is described. Poly(N-methylpyrrole) is shown to constitute an anion exchanger in the oxidized state. The incorporation of negative fixed charges into the polymer matrix makes the film a cation-exchanger.

The contact potential difference or Volta potential
1958Sometime 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 potential of second phase particles in extruded AZ80 magnesium alloy
Electrochimica Acta, 2006Magnesium alloys show strong susceptibility to localized corrosion when immersed in aggressive solutions (e.g. chlorides). The existence of second phase particles in the microstructure might represent initiation sites for localized corrosion. This is due to the formation of galvanic couples between the particles and the matrix.

Elimination of Volta-Potential Noise from Plate Field Mills
Review of Scientific Instruments, 1967The Volta effect severely limits the use of conventional plate field mills in detecting weak electric fields. A modified field mill is described which eliminates the influence of the Volta noise on the measurement. This is achieved by changing the distance between the electrodes during the operation of the instrument.

The Story of the Volta Potential
1991The 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.

Experimental study of Volta potentials in water/nitrobenzene systems with anion adsorption
Journal of Electroanalytical Chemistry and Interfacial Electrochemistry, 1986Abstract The Volta potential of the water/nitrobenzene interface has been measured in the presence of tetraethylammonium picrate and sodium tetraphenylborate. The effect of the latter salt on the changes in surface potential and surface tension of both water and nitrobenzene-saturated water was also studied.

Volta potentials in the water/1,2-dichloroethane and water /nitroethane systems
Journal of Electroanalytical Chemistry and Interfacial Electrochemistry, 1990Abstract 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.

Volta Potential of Oxidized Aluminum Studied by Scanning Kelvin Probe Force Microscopy
The Journal of Physical Chemistry C, 2010The Volta potential difference (VPD) of oxide layers formed on an aluminum surface as a result of anodization in a neutral solution of boric acid, thermal oxidation in air, and immersion in boiling water was studied by scanning Kelvin probe force microscopy. The measured VPD value was correlated with the layer thickness.
