I probably can get the articles free. Libraries, especially University
Libraries can order them for free and you get a copy, but it can be very slow.
I subscribe to a service where I can only order a few a month and I can't make
copies, but could screenshot short selections. That should be adequate.
You can "rent" generally for a short period of time for $3 or $4 usd. "Rent"
means you can only view them online. For $25 usd a month you can have rent 25
articles for as long as you subscribe. I have been very pleased with the wide
selection of journals though it can be very difficult to locate what you are
looking for.

Subject: Re: [Vo]:How to SAFELY make Nickel Nano Powder.
If you browse google for nickel nanopowder and hydrogen, then you
find countless scientific research articles.
Of course almost all must be payed.
It is mentioned that water resulting from the process can poison the
process and this is still heavily researched.
There is not one process, there are hundrets of research and
proprietery industrial processes that involve nickel powder and
hydrogen.
Yes Nickel powder and Raney nickel can self ignite on air and is
dangerous and toxic but there are no dangers in combination with
hydrogen mentioned. The biggest danger is, it doesnt work, and they
try all tricks to make it work.
Especially never neutrons or soft gamma-rays or gamma-ray injury of
persons where reported.

One would not have to use pure Hydrogen; I bet they have
identified an H2-Noble Gas mixture that is slow-enough to be
safe. You can dissolve most metals in acid and cause them to
precipitate as nano-particles. The you would expose it to your
gas mixture.
