UT Dallas researchers create fridges with a twist

January 24, 2020

By twisting small fibers, a new device produces changes in temperature. Years from now, it could change the way we cool things down. – Dallas scientists have developed a fundamentally new approach to cooling things down — by understanding that twisting and untwisting fibers can result in temperature changes. For example, as a thin rubber strand is twisted tightly, the strand gets quite hot. As the rubber untwists, it cools. Researchers at the University of Texas at Dallas affixed fibers

Scientists Make Strong, Super-tough Carbon Sheets at Low Temperature

June 14, 2018

Material’s Properties Exceed Those of Carbon Fiber Composites Used in Aircraft Bodies, Sports Equipment An international research team led by scientists at Beihang University in China and The University of Texas at Dallas has developed high-strength, super-tough sheets of carbon that can be inexpensively fabricated at low temperatures. The team made the sheets by chemically stitching together platelets of graphitic carbon, which is similar to the graphite found in the soft lead of an ordinary pencil. The fabrication process resulted

NanoExplorers Program for High-Schoolers Lauded with Award

December 7, 2011

A UT Dallas program aimed at igniting interest in the sciences among high school students earned a Tech Titan award from the Metroplex Technology Business Council (MTBC). The George A. Jeffrey NanoExplorers program at UT Dallas was awarded the annual Tech Titan of the Future award from the council. Dr. Ray Baughman, director of the Alan G. MacDiarmid NanoTechnology Institute at the University, founded the NanoExplorers program in 2002 as a way to bring in promising pre-collegiate students to conduct

UT Dallas Researchers Spin Nanotech Breakthrough

January 24, 2011

UT Dallas nanotechnologists have invented a groundbreaking new technology for producing weavable, knittable, sewable and knottable yarns containing giant amounts of otherwise unspinnable powders. A tiny amount of host carbon nanotube web holds guest powders in the corridors of highly conducting scrolls, without altering their performance for high-tech applications such as energy storage, energy conversion and energy harvesting. With conventional technology, powders are either held together in a yarn using a polymer binder or incorporated on fiber surfaces. Both approaches
