Research by UT Dallas engineers could lead to more-efficient cooling of electronics, producing quieter and longer-lasting computers, and cellphones and other devices. Much of modern technology is based on silicon's use as a semiconductor material, but research recently published in the journal Nature Materials shows that graphene conducts heat about 20 times faster than silicon. "Heat is generated every time a device computes," said "Dr. Kyeongjae "KJ" Cho, associate professor of...

Enhanced Graphene Could Lead To Better, Smaller Electronics

A team of U.S. and Chinese researchers are claiming that they have developed a new type of graphene that could prevent laptops and other electronic devices from overheating. Mechanical and electrical engineers from the University of Texas at Austin and the University of California - Riverside, along with colleagues from the University of Texas at Dallas and Xiamen University in China, have demonstrated that the thermal properties of isotopically engineered graphene far surpassed those of...

Size matters“¦ but apparently so does shape — when it comes to conducting heat in very small spaces. Researchers looking at the thermal conductivity of boron nanoribbons have found that they have unusual heat-transfer properties when compared to other wire/tube-like nanomaterials. While past experiments have shown that bundles of non-metallic nanostructures are less effective in conducting heat energy than single nanostructures, a new study shows that bundling boron...

The surprising discovery of a new way to tune and enhance thermal conductivity — a basic property generally considered to be fixed for a given material — gives engineers a new tool for managing thermal effects in smart phones and computers, lasers and a number of other powered devices. The finding was made by a group of engineers headed by Deyu Li, associate professor of mechanical engineering at Vanderbilt University, and published online in the journal Nature Nanotechnology...

Rensselaer Polytechnic Institute researchers create large marble-sized pellets of thermoelectric nanomaterials Waste heat is a byproduct of nearly all electrical devices and industrial processes, from driving a car to flying an aircraft or operating a power plant. Engineering researchers at Rensselaer Polytechnic Institute have developed new nanomaterials that could lead to techniques for better capturing and putting this waste heat to work. The key ingredients for making marble-sized...

Neutron analysis of the atomic dynamics behind thermal conductivity is helping scientists at the Department of Energy's Oak Ridge National Laboratory gain a deeper understanding of how thermoelectric materials work. The analysis could spur the development of a broader range of products with the capability to transform heat to electricity. Researchers performed experiments at both of ORNL's neutron facilities -- the Spallation Neutron Source and the High Flux Isotope Reactor -- to learn why...

By Anne M Stark, LLNL By combining high pressure with high temperature, Livermore researchers have created a nanocyrstalline diamond aerogel that could improve the optics for something as big as a telescope or as small as the lenses in eyeglasses. Aerogels are a class of materials that exhibit the lowest density, thermal conductivity, refractive index and sound velocity of any bulk solid. Aerogels are among the most versatile materials available for technical applications due to their many...
