The professional society ASM International has elected two researchers at Oak Ridge National Laboratory to the rank of fellow. A former ORNL researcher was also elected.

The materials engineering professional society cited Mariappan Parans Paranthaman “for the development of novel epitaxial buffer layers on textured templates, enabling high critical current density superconductor films, and for developing mesoporous architectures destined for high performance energy storage applications.”

Paranthaman, a distinguished researcher in the lab’s Chemical Sciences Division, has a joint faculty appointment with the University of Tennessee’s Bredesen Center in Knoxville as a professor. He is also a distinguished UT-Battelle inventor who has authored or co-authored more than 350 publications and has been awarded 28 U.S. patents. His awards include four R&D 100 Awards and three national and two regional Federal Laboratory Consortium awards for developing high performance second-generation superconducting wires for electric-power applications.

Bruce Pint, a researcher in the Materials Science and Technology Division, was cited for “groundbreaking contributions to the fundamental knowledge of high temperature oxidation mechanisms in alloys and coatings, and for contributions to heat resistant alloy design and development through the incorporation of minor elements to control and improve high temperature stability and overall oxidation resistance.” [Read more…]

Scientists at Oak Ridge National Laboratory have developed a new oxygen “sponge” that can easily absorb or shed oxygen atoms at low temperatures. Materials with these novel characteristics would be useful in devices such as rechargeable batteries, sensors, gas converters, and fuel cells.

Materials containing atoms that can switch back and forth between multiple oxidation states are technologically important but very rare in nature, said ORNL’s Ho Nyung Lee, who led the international research team that published its findings in Nature Materials. [Read more…]
