I'm happy to be a part of this community of unknown size. (n=xx) I have to say that Gualtiero is for me somewhat of a true soulmate. Physically we just meet for serval years at the "beloved" department of materials physics at the Royal Inst of Technology where I struggled for ages to get my PhD. At least I finally managed to run up to a dissatation and a Ph.D. thesis which I guess I never had completed in style without Gualtiero patient support mainly on several scientific papers. We had also endless discussions of more important things than oxidation sites of Ce. ;) Since we kept contact even if the physical distance increased. But what is this in a world where we are constantly connected. Ciao and talk to you soon again.
