Polyphase wireless power transfer system achieves 270-kilowatt charge, s...
The global marketplace demands constant improvements in performance and efficiency of aircraft engines, power turbines and other modern mainstays of energy technology. This progress requires advanced structural materials, such as ceramic composites and metal alloys with higher-t...
A group of nuclear detectives at the Department of Energy’s Oak Ridge National Laboratory takes on tough challenges, from detecting illicit uranium using isotopic “fingerprints” to investigating Presidential assassination conspiracies.
Rechargeable batteries power everything from electric vehicles to wearable gadgets, but obstacles limit the creation of sleeker, longer-lasting and more efficient power sources. Batteries produce electricity when charged atoms, known as ions, move in a circuit from a positive end ...
Scientists at the Department of Energy’s Oak Ridge National Laboratory are pioneering the use of infrared cameras to image additive manufacturing processes in hopes of better understanding how processing conditions affect the strength, residual stresses and microstructure of ...
Understanding where and how phase transitions occur is critical to developing new generations of the materials used in high-performance batteries, sensors, energy-harvesting devices, medical diagnostic equipment and other applications. But until now there was no good way to study a...
The Department of Energy’s Oak Ridge National Laboratory, FCA US LLC, and the foundry giant, Nemak of Mexico, are combining their strengths to create lightweight powertrain materials that will help the auto industry speed past the technological
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...
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...
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...
Moving rods of spent nuclear fuel (SNF) to interim storage or a geologic repository requires road or rail travel. Although a heavy shielding cask protects the rods, long distance transportation subjects SNF to vibrations, sudden movements and other potentially agitating for...
