STM studies of p-Si(111) substrate in air and in electrolytic environment
Autor: O. Velev, J. O'm. Bockris, A. González-Martín, M. Szklarczyk
Publikováno v: Surface Science. 237:305-311
Scanning tunneling microscopy was used to study p-Si(111) surfaces in electrolyte solution and in air as well. The dependence of STM images on the sign and magnitude of tunneling bias voltage, as well as on the surface environment, was detected. This

On electrochemical tritium production
Autor: O. Velev, G.H. Lin, R. C. Kainthla, N.J.C. Packham, J. O'm. Bockris
Publikováno v: International Journal of Hydrogen Energy. 15:537-550
This paper reports tritium formed in LiOD-D2O solutions in which Pd cathodes are used to evolve D2. Electrolysis was carried out for up to 412 months. Excess heat has been observed from 5 electrodes out of 28, tritium in 15 out of 53 but 9 out of 13

Polymeric Perfluoro Bis‐Sulfonimides as Possible Fuel Cell Electrolytes
Autor: M. S. Gillette, D. D. DesMarteau, A. J. Appleby, Supramaniam Srinivasan, J. K. Ghosh, A. Parthasarthy, J. ‐G. LeHelloco, O. Velev
Publikováno v: Journal of The Electrochemical Society. 140:109-111
Linear polymeric chain perfluorinated bis-sulfonimides have been synthesized. They are stable strong acids with interesting properties as electrolytes. Like sulfonic acids, they are hydronium ion conductors which require the presence of water to obta

Eight chemical explanations of the Fleischmann-Pons effect
Autor: G.H. Lin, M. Szklarczyk, O. Velev, J. C. Wass, N.J.C. Packham, R. C. Kainthla, L. Kaba, J. O'm. Bockris
Publikováno v: International Journal of Hydrogen Energy. 14:771-775
Eight possible explanations for the heat produced in the Fleischmann-Pons effect are examined with the various conservative assumptions concerning the quantities used. No individual explanation is sufficient to explain the heat produced. All of them

Adsorption of n-amyl alcohol on the (111) and (100) faces of silver
Autor: A. Popov, T. Vitanov, O. Velev
Publikováno v: Journal of Electroanalytical Chemistry and Interfacial Electrochemistry. 256:405-410
The adsorption of n-amyl alcohol on the (111) and (100) faces of silver has been investigated. Some adsorption parameters have been estimated. It is shown that the (100) face adsorbs organic molecules more strongly.
