Put diamond powder into nickel powder will be effective?
I know a group who are very competent, they have tried directly adding industrial diamond powder with hydrogenated Ni without any conclusive results. This is quite different.
As a reminder btw, I attach a couple of photographs I took in the summer, one of a dental X-Ray plate exposed to a LION tube 'post event' (grey) and another microphotograph of the inside of a fuel-tube fragment. (yellow)Plenty of 'pairs' visible here.
