  • The Born-Green equation for liquid metals 
    Kumaravadivel, R.; Evans, R.; Greenwood, D.A. (1974)
    Conflicting reports have appeared in the literature concerning the usefulness of the Born-Green equation to determine effective interionic pair potentials in liquid metals from measured structure factors. To elucidate the ...
  • Pair potentials and structure factors of liquid alkali metals 
    Kumaravadivel, R.; Tosi, M.P. (Società Italiana di Fisica, 1984-07)
    Measured structure factors of liquid alkali metals are examined in the framework of screened pair potential theory. Information on the main attractive well in the effective pair potential is obtained from the structural ...
  • Calculations of the surface energy of simple liquid metals 
    Kumaravadivel, R.; Evans, R. (1975)
    Calculations of the surface energy of eleven liquid metals are presented. These are based on the recently proposed pseudo-atom theory of Evans (see abstr. A72625 of 1974). The results are in good agreement with experiment ...
  • Effect of morphology on electron drift mobility in porous TiO2 
    Aduda, B.O.; Ravirajan, P.; Choy, K.L.; Nelson, J. (2004)
    Porous titanium dioxide is an attractive material for solar cell application on account of its stability, electron transport properties, and the possibilities for controlling surface morphology as well as for its ease of ...
  • Hybrid polymer-metal oxide thin films for photovoltaic applications 
    Boucle, J.; Ravirajan, P.; Nelson, J. (The Royal Society of Chemistry, 2007)
    We review progress in the development of organic-inorganic hybrid photovoltaic materials consisting of a conjugated polymer as an electron donor and a nanocrystalline metal oxide as the electron acceptor. We distinguish ...
  • Important Gorsky effect influences on diffusion coefficients in metal-hydrogen systems 
    Kandasamy, K.; Lewis, F.A. (Elsevier Science Ltd,Exeter, United Kingdom, 1999-08)
    Gorsky effect involvements in regard to the diffusion of hydrogen in metallic solids has meant that, in addition to operations of concentration gradients, expansion effects of interstitials themselves can promote a reverse ...
  • Hydrogen-induced changes of magnetic properties of iron-chromium multilayers 
    Kandasamy, K.; Masuda, M.; Hayashi, Y. (Elsevier Sequoia SA,Lausanne, Switzerland, 1999-06)
    The influence of hydrogen implantation on the structural, magnetic and electrical properties of iron-chromium (Fe/Cr) multilayers was investigated. Hydrogen implantation increases the bi-layer thickness, lattice constant, ...
  • Hydrogen-induced changes of the magnetic properties of copper-cobalt multilayers 
    Kandasamy, K.; Masuda, M.; Hayashi, Y. (Elsevier Science B.V., Amsterdam., 1999)
    The influence of hydrogen implantation on the structural, magnetic and electrical properties of cobalt-copper multilayers was investigated. Hydrogen implantation increases the bi-layer thickness, the separation of crystal ...
  • Hydrogen pressure and electrical resistivity dependencies on hydrogen content in the Pd81Pt19 Hn system 
    Kandasamy, K.; Lewis, F.A.; Sakamoto, Y.; Tong, X.Q. (Elsevier Science Ltd,Exeter, United Kingdom, 1999-08)
    Combinations of knowledge of the hydrogen pressure-hydrogen content-temperature (p-c(n)-T) relationships of the Pd81Pt19 Hn system, and of the dependency of hydrogen content, n, in Pd81Pt19 on electrical resistivity, have ...
  • Hydrogen chemical potentials and phase transitions in palladium black electrodeposits 
    Kandasamy, K.; Lewis, F.A.; McKee, S.G. (1988-10)
    Results are reported of electrode potential and electrical resistance measurements which provide evidence of subsurface hydride transitions in palladium black electrodeposits at much lower equivalent hydrogen vapour pressures ...
  • Fermi levels of FCC and FCT hydrides of Ti and Zr 
    Kandasamy, K.; Surplice, N.A. (1984-03-05)
    Measurements of the work functions of films of TiHx and ZrHx during the FCC/FCT transition have given the change of Fermi level between these two phases of the hydrides. The results agree with modern calculations of the ...
  • Changes of resistance, work function and Fermi level during the hydriding of Zr and Sc at 295K 
    Kandasamy, K.; Surplice, N.A. (1985)
    The turning points on the curve of resistance versus atomic ratio ( gamma =H/Me) were correlated with the phase boundaries of the H/Zr and H/Sc systems at 295K. The changes of work function with r showed that, at low value ...
