"Nanotechnology and Earth? Their relationship may astound you!"
(Special Event)
Michael Hochella, University Distinguished Professor, Geosciences will speak at the Virginia Tech Roanoke Center's Distinguished Faculty Research. The event will be held at the Roanoke Higher Education Center, 108 N. Jefferson Street, Roanoke, VA.
Most people, even those trained in science, may have no idea what nanotechnology has to do with planet Earth. It turns out that the normal functioning of the Earth, from its inception, has been a massive generator of nanoparticles, far more abundant and chemically diverse than anything mankind will ever create. Do you remember (or did you think about) your last breath? OK, no, but take another one right now. You just breathed in about 50 million of them, some naturally occurring, some as a result of human activity. How about the last glass of water you drank, or the dirt in your garden that you will dig into this spring? You guessed it . . . nanoparticles are everywhere, for many reasons and doing many things, some good, and some not so good. Perhaps surprisingly, we have not known about this for long, and our present knowledge is thin, to say the least. But what we have determined to date, in this only recently uncovered nano-world, is simply fascinating
