A metallic sample : before H absorption (left) and after H desorption (right),

illustrative of the effect of H cycling (in/out), fifty times, at room temperature, with a Palladium bulk solid sample (wire).

This is another simple example of what we're interested in : 


Phase Diagrams*.

Our GOAL is to fill the blancks in the literature (with a systematic approach). When H is inserted in a metallic lattice, its basic properties are modified (either improved, or degraded). Even the most studied M-H system, namely Pd-H, still has some MAJOR voids remaining in most of its physical properties, especially in dependance of its H-to-Pd ratio.

* This one is a "P-x-T"-type phase diagram, for the Pd-Hx system (bulk samples). This plot was made by H. Frieske and E. Wicke using desorption isotherms (decomposition pressures). The blue zone was built up via Magnetic Susceptibility desorption isotherms (much more precise). This plot can also be found in the Chap. 3 of the Bible "H in M, II, 1978" : here (page 81). This picture has been taken from Jeffrey M. Wheeler's Ph.D. Thesis (page 60). 

We also address exciting subjects in the field of "H in M",
with the intention to shed light on :

puzzling results ...
and results covered by forgetfulness.

longstanding and current enigmas

The i2-HMR

: gathers passionate, determined and enthusiast researchers around

fundamental properties of "Material-Hydrogen" systems

: works for Science and thus works for the benefit of all Humanity
****

Our research will impact the following fields :

H energy, H embrittlement, H storage, Electricity, Transport, ... in the mid-long term.
The very details of our current research investigations will be shared as soon as achieved
(i.e. with the final step : published papers). We believe that a useful information for the community needs time and many verifications prior to be shared. So : action and prudence. Slowly but surely.

Under construction ...

The i2-HMR's website is under construction.
What you see (the whole website) is a 1st shot (a first draft). Many things are missing.

We make it by ourselves ... so it takes time ... and since we're not skilled in website design/construction ... we expect that you will keep cool with us ;)
Besides, our English is not astonishing as you can see ;) An effort will be made to correct it throughout the website, as soon as possible.
