Mastromatteo determined a procedure by pure chance when he loaded a Pd plated nickel foam.
By asking him a lot of questions at last ICCF, I put forward this procedure that he had not seen.
He loads in H2 first, then he's waiting for pressure drop up to stabilization then unload by temperature both with pumping, then repeats these cycles up to 5X. The pressure always goes on and on faster with each cycle.
However, no excess at this stage.
After last H2 cycle pumped, now it loads with D2, pressure drop is much lower than in H2, He made also several cycles with D2 too.
After that when pressure didn't drop anymore, XH as well as neutrons appear.
Btw, as member from team that won European funding 2020, he will persevere in this direction, for sure.
