(H in Pd and its FCC alloys) - bulk samples
Analytical Chemistry, Materials Science, Processes

Research Scientist / i2-hmr's Vice-President

Research Interests :
Interaction of Hydrogen with Pd and its FCC alloys.
He also has other research interests (@ University of Montpellier - IBMM) : biomolecules. See his RG profile.

(H in Pd and its FCC alloys) - bulk samples
Materials Science, Chem. Phys., Phys. Chem.
Research Scientist / i2-HMR's President

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 :
- SAV.
- 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.

Note that we are not paid (i.e. we don't receive any income) from The i2-HMR.

Our work done under the name "i2-HMR" is thus made as volunteers (part time or full time) since 2013. This situation is simply explained by a cruel lack of funds. We manage to survive this situation e.g. with a further job (paid), but obviously it slows down our scientific work. Some of us can't do that (because of the scientific work load in The i2-HMR requiring a full time dedication) and do survive using social minimum income given by the French government. If you can help us (even with small donations) that's GREAT !! So please, go to "Support us". Many many thanks !!!!

Former members

Mathieu VALAT

left the i2-HMR (i.e. is not an i2-HMR member anymore) since Saturday 26th August 2023. This is due to different and incompatible approaches, visions and way to work between Mathieu Valat and Nicolas Armanet. That being said, we acknowledge Mathieu for his support and encouragements for years. We wish him success in his current and future scientific investigations.

Anthony VOGT

Materials Scientist, Thony investigates physical properties of metallic thin films (elaboration and characterization). He now works for a private company (whose field has nothing to do with M-H). While his work load doesn't allow any participation to The i2-HMR anymore, he closely follows what we do ;) .
