Polyphase wireless power transfer system achieves 270-kilowatt charge, s...
Energy-sapping defects in solar cell material can be revealed with an unprecedented, dual-imaging method established by researchers at Oak Ridge National Laboratory. ORNL scientists scanned hybrid perovskite films to measure “dark” electronic trap states in complex photovoltaic materi...
Research led by Oak Ridge National Laboratory and published in Nature Communications explored building blocks of future electronics — ferroelectric materials in which topological defects called domain walls can be created by an electric field and detected by an alternating current. Th...
The gap between electricity generation and use could be narrowed with an Oak Ridge National Laboratory system that extracts energy from thin air. Actually, Ground-Level Integrated Diverse Energy Storage, or GLIDES, stores electricity mechanically in the form of compressed gas that disp...
Hard carbon materials recycled from tires continue to show great promise as anodes in sodium-ion batteries for large-scale energy storage, according to an Oak Ridge National Laboratory study led by Yunchao Li. The carbons, captured by pyrolyzing, or baking in the absence of oxygen, tir...
Silicon carbide-based materials could be a winning alternative to zirconium alloys commonly used in fuel and core structures in today’s light water reactors, according to preliminary findings of a team led by Yutai Katoh of Oak Ridge National Laboratory. “Fuels and core structures in c...
A successful test of 3D-printed thermoplastic molds demonstrates the potential of additive manufacturing in the tooling industry. Researchers at Oak Ridge National Laboratory’s Manufacturing Demonstration Facility collaborated with a team of industry partners to 3D-print and machine se...
Minimizing the impact on freight movement when events like Hurricane Sandy happen is the focus of an Oak Ridge National Laboratory ongoing study led by Marc Fialkoff, a researcher in the Geographic Information Science and Technology Group. “In the aftermath of disasters, planners and...
When life gives you lemons, make lemonade. At Oak Ridge National Laboratory and Uppsala University, researchers have done the scientific equivalent by using, rather than eliminating, flaws inherent to electron microscopy to create probes for performing novel atomic-level spectroscopy.
Clothes dryers that use thermoelectric heat pump technology being developed by Oak Ridge National Laboratory and industry partner Sheetak could use 40 percent less energy, potentially saving consumers $3 billion in utility costs. “Each month, electric clothes dryers typically consume more energy than any other household appliance,” said Kyle Gluesenkamp, who leads the development team for ORNL’s Building Equipment Research Group.
Fish communities recovering from environmental disturbances could potentially face obstacles presented by road culverts and equipment used to monitor water quality, according to an Oak Ridge National Laboratory study conducted over two decades. Researchers Ryan McManamay and Robert J...
