Polyphase wireless power transfer system achieves 270-kilowatt charge, s...
A novel approach that creates a renewable, leathery material—programmed to remember its shape—may offer a low-cost alternative to conventional conductors for applications in sensors and robotics. To make the bio-based, shape-memory material, Oak Ridge National Laboratory scientists streamlined a solvent-free process that mixes rubber with lignin—the by-product of woody plants used to make biofuels.
A novel approach for studying magnetic behavior in a material called alpha-ruthenium trichloride may have implications for quantum computing. By suppressing the material’s magnetic order, scientists from Oak Ridge National Laboratory and the University of Tennessee observed be...
Using a novel, reusable carbon material derived from old rubber tires, an Oak Ridge National Laboratory-led research team has developed a simple method to convert used cooking oil into biofuel.
An Oak Ridge National Laboratory–led team discovered that vanadium dioxide in a crystalline thin film makes an outstanding electrode for lithium-ion batteries. Theory and computation predicted a high capacity for lithium storage, which experiments confirmed with tests in coin c...
Oak Ridge National Laboratory has successfully developed and tested a novel sand casting technique to quickly design complex patterns to fabricate components for industry partner Emrgy Hydro, makers of hydropower devices designed to generate electricity from slow or shallow water flo...
Advanced manufacturing will benefit from additive manufacturing techniques as demonstrated by a team led by Michael Kirka of Oak Ridge National Laboratory.
Scientists have developed a process for mixing unmodified lignin with general-purpose rubber and other components that yields high-performance renewable thermoplastics containing up to 41 percent of lignin content. The Oak Ridge National Laboratory-led research team tested two combinations of materials using different lignin varieties resulting in samples that were either “stretchy” or demonstrated tensile strength comparable to glassy plastic such as acrylonitrile butadiene styrene, or ABS.
A multi-institution team led by Oak Ridge National Laboratory’s Gaute Hagen used computation to corroborate experimental findings throwing calcium-52’s status as a magic isotope into question.
Researchers at Oak Ridge National Laboratory are using bamboo fiber in 3-D printing experiments to determine whether bio-based feedstock materials are feasible in additive manufacturing.
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...
