Ultrasonic imaging and submarine sonar technologies often rely on materials called ferroelectric relaxors, which are known for their unique electromechanical properties. A study published in Advanced Functional Materials from a team including Oak Ridge National Laboratory has revealed several mechan...
Researchers at Oak Ridge National Laboratory have achieved a friction-stir technology milestone by extruding aluminum-based wire in lengths up to 15 feet. Friction-stir, which is also used in welding, is a method that uses the heat from a spinning tool to plasticize metal alloys or composites for re...
By applying the magnetic properties of iron nanodots to complex materials, a research team has overcome an obstacle to getting ultra-thin or highly strained films to perform on par with their bulk counterparts. If the researchers are indeed successful, this work sets the stage for these exotic mater...
A newly patented technology from Oak Ridge National Laboratory can help extend the lifetime of batteries in plug-in hybrid vehicles by optimizing the battery's state of charge while driving. Developed by ORNL's Robert DeVault, the computerized control uses data about recharging locations to improve ...
Plasmonic, or metallic, nanostructures are one step closer to fulfilling their promise as next-generation sensors and devices for high-speed communications because of research performed by scientists at Oak Ridge National Laboratory and Fudan University. Despite the potential, a big challenge has be...
An estimated $1 billion in lost revenue each year is fueling an effort by Oak Ridge National Laboratory to prevent fuel tax evasions. The system being developed by a team led by Gary Capps will use evidential reasoning techniques, fuel markers, sensor and vehicle tracking devices to monitor, track a...
Capillary action and graphite foam are being enlisted by researchers at Oak Ridge National Laboratory to solve a logistical nightmare for the military and U.S. troops deployed around the world. While soldiers require nearly seven gallons of water a day, just getting that water to them increases troo...
By reducing a material to the same nano scale as the electronic regions that reside within, researchers have gained a better understanding of the dynamics of electronic phase transitions. This information is critical to advances in several technologies that rely on competing resistive states such as...
Despite an overall warming trend, extreme cold events are still likely to persist for the next century, according to research published by Evan Kodra, Karsten Steinhaeuser and Auroop Ganguly of Oak Ridge National Laboratory. The Southeast and Northwest regions of the United States may be especially ...
