April 16, 2014 — Electrical engineers at the Georgia Institute of Technology recently published a “roadmap” that details innovative analog-based techniques that could make it possible to build a practical neuromorphic computer that mimics the brain’s operation.
April 6, 2014 — A combined computational and experimental study of self-assembled silver-based structures known as superlattices has revealed an unusual and unexpected behavior: arrays of gear-like molecular-scale machines that rotate in unison when pressure is applied to them.
March 30, 2014 — By harnessing an electropolymerization process to produce aligned arrays of polymer nanofibers, researchers have developed a thermal interface material able to conduct heat 20 times better than the original polymer — operating at temperatures of up to 200 degrees Celsius.
March 10, 2014 — A new type of biomolecular tweezers could help researchers study how mechanical forces affect the biochemical activity of cells and proteins. The devices – too small to see without a microscope – use opposing magnetic and electrophoretic forces to precisely stretch the cells and molecules.
February 18, 2014 — Researchers have developed the technology for a catheter-based device that would provide forward-looking, real-time, three-dimensional imaging from inside the heart, coronary arteries and peripheral blood vessels. With its volumetric imaging, the new device could better guide surgeons working in the heart.
February 18, 2014 — A research collaboration has demonstrated the world’s fastest silicon-based device to date. The investigators operated a silicon-germanium (SiGe) transistor at 798 gigahertz (GHz) fMAX, exceeding the previous speed record for silicon-germanium chips by about 200 GHz.
February 5, 2014 — Using electrons more like photons could provide the foundation for a new type of electronic device that would capitalize on the ability of graphene to carry electrons with almost no resistance even at room temperature – a property known as ballistic transport.
January 15, 2014 – Ford Motor Company, in collaboration with Georgia Tech, debuted a new solar car concept earlier this month at the 2014 International CES in Las Vegas. The car is continuing its media tour this week at the North American International Auto Show in Detroit.
December 12, 2013 — Researchers are taking advantage of the unique properties of graphene to design tiny antennas that may open the possibility for networks of nanometer-scale machines. Graphene could generate a type of electronic surface wave that would allow antennas just one micron long and 10 to 100 nanometers wide to do the work of much larger antennas.
December 9, 2013 — Researchers are developing a family of generators that provide power for portable electronic devices and sensors by harnessing the triboelectric effect to capture mechanical energy that would otherwise be wasted.
