Research Scientist (experimenter) / i2-hmr's Vice-President

Research Interests :
Interaction of Hydrogen with Pd and its FCC alloys.

Birth : Nov. 25, 1988.

(H in Pd and its FCC alloys) - bulk samples
Materials Science, Chem. Phys., Phys. Chem.
Research Scientist (experimenter) / 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.

* : structural, of transport, mechanical, thermodynamical, kinetical, electronic, magnetic, etc ...

Birth : April 02, 1980.
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.

François, mainly full time, gives private lessons from High-School level to Master level in Mathematics, Physics, Chemistry, and therefore performs research activities on M-H, occasionally.
Michel, full time, works on biomolecules, and therefore performs research activities on M-H very occasionally.
Nicolas works full time on the Pd-H system (through various projects) and manages to (financially) survive using social minimum income given by the French government. But given the drastic increase of the cost of living in France (since, say, 2022) he now works (paid job) at his family's restaurant on Friday and Saturday, letting only 4 days (Monday to Thursday) dedicated to M-H science - plus Sunday for rest.

Regretfully, such a situation (cruel lack of funds) prevents us to be full-time dedicated to M-H research and therefore considerably slows down our scientific work.
It's why we search funding. Should you be willing to support us, feel free to visit our page "Support us". Thank you !

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 ;) .
