April 26, 2013 — Using bundles of vertical zinc oxide nanowires, researchers have fabricated arrays of piezotronic transistors capable of converting mechanical motion directly into electronic controlling signals. The arrays could help give robots a more adaptive sense of touch, provide better security in handwritten signatures and offer new ways for humans to interact with electronic devices.
April 16, 2013 — Researchers are developing a novel technology that would facilitate close monitoring of bridges, parking decks and other structures for early signs of strain, stress and formation of cracks. Their approach uses wireless sensors that are low cost, require no power, and can be implemented on tough yet flexible polymer substrates.
April 9, 2013 — Controlling the shapes of nanometer-sized catalytic and electrocatalytic particles made from noble metals such as platinum and palladium may be more complicated than previously thought. Using systematic experiments, researchers have investigated how surface diffusion – a process in which atoms move from one site to another on nanoscale surfaces – affects the final shape of the particles.
April 2, 2013 — Researchers from the Georgia Institute of Technology have won a Defense Advanced Research Projects Agency (DARPA) contract to develop three-dimensional chip-cooling technology able to handle heat loads as much as ten times greater than systems commonly used today.
March 29, 2013 — Researchers have developed an ultra-compact passive true time delay device that could help reduce the size, complexity, power requirements and cost of phased array designs. The device uses the difference in speed between light and sound to create nanosecond signal delays.
March 19, 2013 — A team of researchers at Georgia Tech has developed a new type of interface between cochlear implant devices and the brain that could dramatically improve the sound quality of the next generation of implants. Cochlear implants help deaf individuals perceive sound.
February 27, 2013 — Researchers have demonstrated the use of a technique known as small angle neutron scattering (SANS) to study the effects of ions moving into nanoscale pores. The study is believed to be the first application of the SANS technique for studying ion surface adsorption in-situ.
December 13, 2012 — A device designed by engineers at the Georgia Tech Research Institute (GTRI) is part of the Hurricane Imaging Radiometer (HIRAD), an experimental airborne system developed by the Earth Science Office at the NASA Marshall Space Flight Center in Alabama.
December 10, 2012 — Researchers are creating graphene p-n junctions by transferring films of the electronic material to substrates that have been patterned by compounds that are either strong electron donors or electron acceptors.
November 19, 2012 — By fabricating graphene structures atop nanometer-scale “steps” etched into silicon carbide, researchers have for the first time created a substantial electronic bandgap in the material suitable for room-temperature electronics. Use of nanoscale topography to control the properties of graphene could facilitate fabrication of transistors and other devices, potentially opening the door for developing all-carbon integrated circuits.
