RE: EXTERNAL: [Vo]:OxyVac?

Scott,
Why oxygen over an inert gas? I would fear the oxygen would 
either form oxides with the nickel or alloy surfaces which would then short out 
the Casimir geometry, Or start disassociating and then reforming molecular O2 
rapidly due  to changes in the smallest Casimir geometry which would then 
create hot spots that melt closed or grow whiskers across the most active sites.

I have wondered why a better vacuum might be made by filling it with oxygen, 
pumping it out, then chemically trapping the rest of the oxygen. --Not saying 
its a good idea, but does anyone care to comment?

Dear Fran,

We are thinking differently. In this case Piantelli obtains his nanoNi by a 
physical method method, Molecular Beam Epitaxy with the desired morphology and 
the active sites have to be made free, cleaned. . Not the case of partially 
damaged  sites.

There are many physical and chemical processes of making nanoNI- perhaps Rossi 
has found a better one.

Vacuum mills is an excellent idea in principle- how high a vacuum can be 
achieved and maintained?

Alloys opens a new dimension, it is possible some will work better even than 
Ni- but only experiment can say.

Re Cleaning I give you an example from my practice. Some acrylic monomers are 
extremely sensible to the presence of Sulphur compunds, even under 1 ppm. To 
determine analytically S is an ordeal. The engineers add a spoon of copper salt 
to the batch and S is fixed, harmless. Radical solution.

Peter,
The repeated cleaning cycles used by Piantelli seems like a  
limited method  of partially salvaging damaged   sites.  I would suggest 
instead  to  mill the powder inside a vacuum chamber where even the small 
amount of ambient gases left from the original ore can outgas while the 
geometry is being reduced.  Much smaller geometry should be achieved in vacuum 
without heating of the metal from the reacting gases. The obvious difficulty is 
collecting the pristine millings while still under vacuum and alloying them by 
spin melt or sputtering with the inner reac tor wall surface.  Perhaps the 
external cooling system should be already running and kept running to keep the 
smallest geometry of the forming alloys from collapsing due to the stiction 
forces?  I don't think pristine nano powder  should require pressure loading of 
hydrogen and could even operate with the powder still under partial vacuum.

Yessir! have discussed this with Brian. I have concluded long time ago that CF 
is not reproducible because the active sites are covered with other gases from 
air (as polar as worse) that destroy their activity. For Ni-H I know how does 
the Piantelli Cell work, a lot is in his 2 patents WO1995/20816 and especially, 
WO 2010/58288 please see how drastically- high vacuum, high temperature, many 
cycles is nanoNi cleaned. Piantelli says the presence of
foreign(not hydrogen) gas molecules inhibits the process.

We don't know much about what is Rossi doing, is his system more tolerant to 
air and its impurities. Strem menos has told in one of his interviews how it 
was discovered that the system (which?) works only after deep degassing.

I believe that clean metal surface- is a sine qua non condition for a working 
material/setup. This is a simple,
cut-the-Gordian-Knot type idea. If it works, OK if not you can test all those 
conditions and ideas you describe, that are based on bright theories.

Does anyone have a recipe for removing oxides from Ni powder?

How about baking the Ni nano powder in nitrogen (or He, or ??) Or is a
vacuum best? For how long and at what temperature?

How does one calculate oxide levels in nickel powder to compare one method
over another?

Curious minds want to know...
