WebbIt is known that a quite repeatable way of generating excess heat in the electrolysis Pd/D system is the co-deposition technique (S. Szpak, P.A. Mosier-Boss and J. J. Smith, J. Electroanal. Chem., 302 (1991) 255.). One advantage is that a higher D/Pd ratio is relatively easy to achieve with co-deposition compared to ordinary electrolysis methods. However, … Webb1 dec. 2011 · The Poisson ratio ν of In 2 O 3 has been determined by measurement of the covariation of in-plane and out-of-plane lattice parameters of strained thin films grown epitaxially on (111) and (001) oriented cubic Y-stabilized ZrO 2 substrates.
