Yep - this reeks. When the conclusion of their "necessary IP constraints" is "no one else will be able to verify the material exists or try and make it by the same process" then this turns into junk science.

It's some guy just saying "trust me bro" except he's already been caught out committing academic misconduct.

The history of scientific fraud is full of mysteriously uniquely special researchers who were only able to get their results in their own labs, with their own equipment, when they alone were using it. No end of "free energy" charlatans do the same thing.
