Researchers find that tiny nanowires can lift liquids as effectively as tubes
04/01/2013 - 10:30

New research carried out at MIT and elsewhere has demonstrated for the first time that when inserted into a pool of liquid, nanowires — wires that are only hundreds of nanometers (billionths of a meter) across — naturally draw the liquid upward in a thin film that coats the surface of the wire. The finding could have applications in microfluidic devices, biomedical research and inkjet printers.

In preliminary research by Erik Thostenson and Thomas Schumacher, the two found that a carbon nanotube hybrid glass-fiber composite attached to small-scale concrete beams formed a continuous conductive skin that is exceptionally sensitive to changes in strain as well as to the development and growth of damage.

The current issue of the American Chemical Society journal ACS Nano features an article about work by the Rice lab of chemist Bruce Weisman to understand how the lengths and imperfections of individual nanotubes affect their fluorescence – in this case, the light they emit at near-infrared wavelengths.

Penn Physicists’ New Manufacturing Technique Means Higher Quality Nanotube Devices
10/07/2011 - 13:30

Major advances in materials science and nanotechnology promise to revolutionize electronic devices with unprecedented strength and conductivity, but those promises can’t be fulfilled if the devices can’t be consistently manufactured. Working on the nanoscale means the effects of even the smallest imperfections are magnified, but University of Pennsylvania physicists have developed a new printing technique that is effective at making carbon nanotube devices with minimal impurities.
