For the first time, an innovative research technique successfully completed a detailed measurement of how heat energy is created at the molecular level, an approach that could have far reaching implications for developing nano-devices.
Research results to be published in the upcoming issue of Science, detail a collaborative effort involving The University of Scranton, a Jesuit university in Pennsylvania, and the University of Illinois at Urbana-Champaign, a research institution in Illinois. "This is the first time that anyone has measured how a specific motion of a molecule on one side of a molecular wall causes molecules within the wall to move," said John Deak, Ph.D., assistant professor of chemistry at The University of Scranton. "In nanotechnology, researchers design materials whose properties originate in clusters of molecules on the nanometer level. This research can be used to help us better understand how molecules interact on these dimensions."
The faculty and students involved were Dr. Deak and his undergraduate student Timothy Sechler; and University of Illinois chemistry professor Dana Dlott, Ph.D., Yoonsoo Pang, graduate assistant, and Zhaohui Wang, post-doctoral research associate. "The experiment detailed the pathways for energy transfer and also provided the tools to study other molecules," said Dr. Dlott. "In designing nanoscale devices, the shapes of the molecules must be designed not only to be small and fast, but also to move heat effectively. There is no reason that this technique is not applicable to just about any molecule."

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
