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, … WebbIn distinction to CNT + SiO 2, the CNF–SiO 2 system showed stronger interaction of the amorphous silica film with the end faces of graphite terminating at the external surface of CNF. Calcination of the CNF–SiO 2 composite in an inert atmosphere at 1300 °C for 1 h did not lead to segregation of the components.
