UT-ECE’s Professors Sanjay Banerjee, Frank Register, and Emanuel Tutuc along with Prof. Allan MacDonald, UT Physics Department, and ECE graduate student Dharmendar Reddy designed a novel graphene-based BiSFET device that could revolutionize the chip design industry. This device is discussed in more detail in a recent IEEE Spectrum article.
Professors Sanjay Banerjee and Emanuel Tutuc have demonstrated, for the first time, that centimeter-square areas of copper foils can be covered almost entirely with mono-layer graphene bringing this intriguing material one step closer to commercial viability. Graphene, formed with carbon atoms linked together like nanoscopic chicken wire, holds great potential for nanoelectronics. It also shows promise for electrical energy storage, for use in composites, for thermal management, in chemical-biological sensing, and as a new sensing material for ultra-sensitive pressure sensors.
ECE professor, Dean Neikirk, just received funding for a 5-year program to use wireless sensors to identify failing bridges, lower the cost of monitoring those bridges, and improve the safety of new bridges. The $6.8M project addresses a chronic problem for the aging American highway infrastructure. According to the American Society of Civil Engineers, deferred maintenance has left one-quarter of the nation’s bridges deficient. Congress mandated 2-year inspections in 1971, but at least 17,000 bridges did not meet the requirement in 2008, including 3 out of every 100 freeway bridges.
Dr. Seth Bank's research into III-V compound semiconductors could cool down your laptop, increase the capacity and speed of fiber-optics, and make solar cells more efficient. Bank hopes to improve III-V compound semiconductors—used for everything from cell phone transistors to LED's in traffic lights—by embedding semi-metal nanoparticles in them.
The tongue can be a powerful tool, but also a highly subjective one. Dr. Dean Neikirk developed what amounts to an artificial tongue. When food companies want to create the same flavor every time, they turn to Neikirk's electronic tongue to analyze liquids and pick out their exact chemical make-up. Neikirk's tongue uses microspheres, tiny sensors that change color when exposed to a specific targets, such as certain kinds of sugars. The result is a system that can't replace the person who says, This tastes good! but can make sure the chemistry of good taste is reliably replicated.
