Hello, Matthew. I'm posting your text in the same format that it appears in the archives. It seems there is something wrong with your email/newsreader that introduces extra carriage returns. This makes your post very hard to read. Your previous posts are the same, and Marshall recently had the same problem. Maybe try rebooting. > Hello, Mike, > Merriam-Webster's Dictionary > (1997-2004) defines > the > adjective oligodynamic in its primary > meaning to > be: > "active in very small quantities < > an > oligodynamic germicide>." > The Hutchinson Encyclopedia (2000) > defines it > as > "pertaining to effect of small > quantities; having > effect > in small quantities only." > Stokvius explained the meaning of > oligodynamism > in the Lancet, April 26, > 1894. In 1893, C. Von Nageli reported the first systematic "investigation into the lethal effects of metals [especially silver] towards bacteria and lower life forms.... To primitive life forms oligodynamic silver is as toxic as the most powerful chemical disinfectants and this, coupled with its relative harmlessness to [animal] life, gives it great potential as a disinfectant.... The term 'oligodynamic '[silver refers to] solutions in which the metal ion concentration is many orders of magnitude below that which would be lethal to higher life forms."(24) 24) N.R.

Powder pattern x-ray diffraction is useless for cs. http://www.matter.org.uk/diffraction/x-ray/powder_method.htm As soon as the cs evaporates, all the silver ions capture hydroxyl ions and form a dark black or brown oxide as described previously. I posted this experiment well over a year ago, but don't have the url handy at the moment. It would appear in the thread "Where do the electrons go" and earlier threads. Frank Key describes the same effect on his web site, but he gets the equations wrong. In any event, evaporated cs tells you little or nothing about the preceeding liquid.

UV would work, but none of these are related to the topic, which is the identity of particles generated by passing current through distilled water using silver electrodes. As I have shown, the particles are oxides, not silver metal. > Best regards, > Matthew Your email/newsreader client is still skipping the "Re: " Best Wishes, Mike Monett -- The Silver List is a moderated forum for discussing Colloidal Silver.
