The Trouble With Photons

Abstract:
What if there was a substance that could be put into the eye to consume these R.O.I.s (reactive oxygen intermediates)? Junping Chen of the University of Oklahoma and colleagues have found a candidate, from the automotive and jewelry industries.

The substance, they report in the journal Nature Nanotechnology, is cerium oxide, tiny particles of which are made from the rare-earth element cerium. Known as nanoceria particles, they are currently used in the catalytic converters that are part of automobile exhaust systems and in jewelry polishing. (2nd story on the page)
