As mentioned, there are persistent reports of NiH reactions. So far, this cannot be considered confirmed, there isn't a single, repeatable protocol that has been independently verified.
That's the reason they pay Your spin-tank (a so called University xy Institute) you still are enganged in. To make people claim that NiH is a dead end.
Your advise is poor, in the sense that You invent Your own nonsense!
There exist may 100% repeatable (high COP) NiH protocols, like the Mizonu PtNiZrCaO -H or the newer PtNiH (D) Nanor protocol...
Knowledge can not be suppressed by FUD! Tell it your patriot Uncle SAM.
