Dear Wm. Scott Smith.
Thank you very much for this kind offer. Maybe others could be interested.
I would have been nosy to look into some of them, but honestly, I am not
a scientist and cannot make real use of them.
Probably I will not understand 80% of the content, and if, then I dont
have the instruments to make vacuum, high pressure and so on. Also the
ingredients, high purity chemicals and so on are expensive.
If had found an article that was VERY interesting for me I would of
course have bought it.
Again, thank you very much, it is very much appreciated.
kind regards,
Peter

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.
