So guys, there was a bigger pause with very few news about these experiments.
But now we have SEM microscope with EDX in our lab just for our disposal. After examining many Cathodes from my runs I found very clear traces of Palladium inside Titanium. It seems to be deeper in the lattice. With 15KV accelerating voltage it can be detected. I found out that doing analysis is just time consuming as hell.
To confirm this is not just an induced impurity I was also carefully examining Anodes and especially original Sponges and other Sponges from the same batch that I have. No Palladium found elsewhere.
It is clearly apparent only in runs that took 2 weeks or more and is detectable rather near the voids in the Sponge. The problem with analysis is that the Sponge is rather fully covered with Lithium.
I will share EDX report as soon as possible. This clearly confirms that some nuclear process is going on there and it is worth of investigation.
