Milling just about anything goes much better in liq N2. They even crush car tires to dust!!!

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.Fran From: Wm.

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?Date: Wed, 15 Jun 2011 21:42:15 +0300 Subject: Re: EXTERNAL: Re: [Vo]:Ahern in Next Big Future From: peter.gl...@gmail.com To: vortex-l@eskimo.com 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.

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.

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 sur face- 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.Peter On Wed, Jun 15, 2011 at 4:22 PM, Roarty, Francis X <francis.x.roa...@lmco.com> wrote: -- Dr. Peter GluckCluj, Romaniahttp://egooutpeters.blogspot.com
