Video of the Week: Titanium dioxide to convert optical energy to mechanical energy

By / June 2, 2010

[flash http://www.youtube.com/watch?v=igYr2RQHWdI preview=force] In a recent interview with Nanowerk, Ayusman Sen, a professor at the Department of Chemistry at Penn State, explained how he uses titanium dioxide to convert optical energy to mechanical energy via photocatalysis. The team’s findings were published recently in Advanced Functional Materials. “The whole system consists only of titania, water, sometimes…
