Engines, laptops and power plants generate waste heat. Thermoelectric materials, which convert temperature gradients to electricity and vice versa, can recover some of that heat and improve energy efficiency. A team of scientists at the Department of Energy’s Oak Ridg...
Quasiparticles—excitations that behave collectively like particles—are central to energy applications but can be difficult to detect. Recently, however, researchers have seen evidence of quasiparticles called negative trions forming and fading in a layer of semiconducting mate...
Steady progress in the development of advanced materials has led to modern civilization’s foundational technologies—better batteries, resilient building materials and atom-scale semiconductors. Development of the next wave of materials, however, is being slowed by the sheer co...
The efficiency of solar cells depends on precise engineering of polymers that assemble into films 1,000 times thinner than a human hair.
Today, formation of that polymer assembly requires solvents that can harm the environment, but scientists at the Department of En...
Electron microscopy at the Department of Energy’s Oak Ridge National Laboratory is pointing researchers closer to the development of ultra-thin materials that transfer electrons with no resistance at relatively high temperatures.
The study delivers direct evidence of high-tem...
Some of the 300 million tires discarded each year in the United States alone could be used in supercapacitors for vehicles and the electric grid using a technology developed at the Department of Energy’s Oak Ridge National Laboratory and Drexel University.
By em...
A catalyst being developed by researchers at the Department of Energy’s Oak Ridge National Laboratory could overcome one of the key obstacles still preventing automobile engines from running more cleanly and efficiently. The mixed oxide catalyst could solve the ...
Secretary of Commerce Penny Pritzker visited the new Institute for Advanced Composites Manufacturing Innovation (IACMI) at Oak Ridge National Laboratory’s Manufacturing Demonstration Facility, praising the advances in manufacturing technology taking place in East T...
In mere seconds, a system developed at the Department of Energy’s Oak Ridge National Laboratory can identify and characterize a solid or liquid sample, providing a valuable tool with applications in material science, forensics, pharmaceuticals, biology and chemistry.
In the Stone, Bronze and Iron Ages, the state of the art of materials science defined technology’s zenith and accelerated economies. Now, in the Information Age, data is beginning to drive the development of advanced materials, from photovoltaics for solar energy and superconductors for efficient el...
