Generating Nano Oscillatory Motion

Posted by kdawson on from the maybe-you-could-power-an-atomic-clock dept.

KentuckyFC sends us to arxivblog.com, where he summarizes (in prose that is somewhat more twee than we usually encounter in writing about physics) the conversion of a constant force into oscillatory motion on the nano scale. Here is the article preprint. A research group at the University of Wisconsin-Madison has made mushroom-shaped nano-pillars that oscillate in a constant DC field, like metronomes.

    I've heard of people doing weird shit with their iPods, but making pillars from Nano's? I guess anything is possible. Sounds expensive, they might want to try to make pillars out of stone or concrete -- it might be cheaper.

      I'm a different AC than the poster moded offtopic above, just so you don't blame him. WFT is up with the humorless dolts relentlessly hammering down 'offtopic' anything not funny in their limited worldview? Stop, just stop, okay? If you don't have a sense of humor, just flag posts with "I'm a farkin clueless HumorNazi". Perhaps we need detailed anal-retentive explanations each time of why something isn't funny. Make sure it's excruciatingly detailed and clueless.

      On another topic, I wonder if these nano pillars could be used in a fluid domain to pump biological substances. I could envision a kind of heart pump maybe that had no moving parts to wear out or break, yet creates a pressure gradient to transport blood cells.

    Coincidentally, to confirm that I'm not a script, I had to type "dissent".

    Amazing.
