His research interests :
do centre on properties of Hydrogen in Palladium (and its FCC alloys).
His goal is to fill the blanks in the literature as for Pd properties* modified by H absorption. There are still significant holes in the literature, as well as unexplored areas, in dependence of H-to-Pd ratio (i.e. x) and of T and P.
Besides, again with Pd-H(D) and its FCC alloys, he works on open questions such as :
- HT Superconductivity.
- Origin of the change of slope at x = 0.75 of dV(x) in the range x = 0 - 1.0
(and related questions such as :
- what is(are) the correct value(s) of vH (A^3 / H atom) ?
- what is the P at which x = 1.0 is achieved (if ever achievable) ? (and the related V0 in A^3 / Pd atom ?).
- which interstitial site(s) is(are) occupied for x <= 1.0 ?
- is there another phase when x approaches x = 1 in addition to the known Beta phase ? (if so : SAV or something else ?)).
- Is(are) there any overstoichiometric phase(s) with Pd-H ? (if so : SAV and/or something else ?). If so, where do H atoms locate ?
- Mechanism of the Hydride formation and decomposition
(and its impact on the behaviour of sample dimensions during H absorption / desorption).
- Origin of the Hysteresis (of P(x) and R(x)).
- And on other mysteries about this M-H system.
