Here's one for you:
My dentist, who enjoys learning, mentioned today that he'd come across a term that dated back to 1918 that he had never come across: electrozone. In an old dentistry text, it was noted that 'electrozone' was an ingredient that could remove malodorous scents from crowns. Problem is: my dentist had no idea what electrozone might have been--and Google hadn't helped me a bit. I assured him that someone here would ferret out electrozone. He did mention that 'zone' is related in chemistry to oxygen--and he suspected that electrozone might have been a kind of peroxide.
Any takers?

I can remember the first home movie projector I ever saw. When it ran, there was a peculiar chemica odor, apparently related to some arcing somewhere in its innards. The owner said it was ozone I was smelling. Maybe that is what was meant by "electrozone". Here's URL with a lot of information about ozone, scroll about a quarter of the way to D: which says no viruses of bacterian are resistant to ozone. So a dental crown that might be damaged by other agents could be sterilized with Ozone. I suspect it might also oxidize odor causing substancws. http://www.deltamarineozone.com/ozonefacts.html

Waterpic, who make water based electic 'flossing machined', also make a machine that used ozone purifided water to wash vegetables.. (for the parinoid!) http://www.waterpik.com/aquia/KitchenFeature.shtmland a huge ozone generator is used by NYC to clean water from the croton aquaduct, the city's oldest. the water is run throught sand and diazomized earth, and is perculated with ozone. that, plus a small shot of clorine is all that is needed- and only now, that the area around the reservoir is getting 'built up'. the new reserviors, (in more remote parts of NY) just need filtering and clorine.

diazomized earth - That's diatomaceous, just to reassure you that it is neither something artificial nor radioactive  : It is silica earth formed from the skeletons of fossil algae.

Diatomaceous earth is used for many things. I had forgotten its use to keep grain from spoiling, and as a pesticide. Because the particles are so very small, it is the best agent available for removing suspended matter in water. http://www.eap.mcgill.ca/Publications/eap4.htm

Diatomaceous earth is used to filtre the water in swimming pools.
