Less than 1 percent of Earth’s water is drinkable. Removing salt and other minerals from our biggest available source of water—seawater—may help satisfy a growing global population thirsty for fresh water for drinking, farming, transportation, heating, cooling, and industry. But desalination is an energy-intensive process, which concerns those wanting to expand its application.

Now, a team of experimentalists led by the U.S. Department of Energy’s Oak Ridge National Laboratory has demonstrated an energy-efficient desalination technology that uses a porous membrane made of strong, slim graphene—a carbon honeycomb one atom thick. The results are published in the March 23 advance online issue of Nature Nanotechnology.

“Our work is a proof of principle that demonstrates how you can desalinate saltwater using free-standing, porous graphene,” said Shannon Mark Mahurin of ORNL’s Chemical Sciences Division, who co-led the study with Ivan Vlassiouk in ORNL’s Energy and Transportation Science Division.

“It’s a huge advance,” said Vlassiouk, pointing out a wealth of water travels through the porous graphene membrane. “The flux through the current graphene membranes was at least an order of magnitude higher than (that through) state-of-the-art reverse osmosis polymeric membranes.” [Read more…]

Three staff members at Oak Ridge National Laboratory have been named fellows of the American Association for the Advancement of Science for scientific contributions that range from administrative leadership to discoveries in the environmental sciences.

Michelle Buchanan, Liyuan Liang, and Melanie Mayes and are among those to receive this year’s recognition to AAAS members by their peers. AAAS is the world’s largest general scientific society and elects fellows based on their distinguished contributions to the advancement of science or its applications, a press release said.

Buchanan is ORNL’s associate laboratory director for physical sciences, where she guides the Chemical Sciences, Materials Science, and Technology and Physics divisions, as well as the Center for Nanophase Materials Science.

She was elected “for exceptional technical leadership and service in the chemical and physical sciences, and for contributions to setting the nation’s research priorities.” [Read more…]

Renowned mammalian geneticist Liane Russell returned Thursday to Oak Ridge National Laboratory to congratulate the first recipients of a new fellowship named in her honor.

ORNL created the Liane Russell Distinguished Early Career Fellowship to attract a diverse and promising work force of early career scientists and engineers whose interests align with DOE missions.

“It is gratifying to see these opportunities being made available to a diverse group of talented young people because, sadly, in the scientific fields this has not always been the case,” Russell said. “For this reason I am particularly honored to have my name attached to the fellowships.”

The competitive, three-year fellowship is aimed toward establishing long-term research careers at ORNL. It is available to outstanding scientists and engineers who have received their doctorate degrees within the past seven years, with emphasis given to attracting women and minority candidates.

The first three Russell fellows, recognized at Thursday’s reception, are: [Read more…]

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…]

Anasys Instruments Corp. has licensed an Oak Ridge National Laboratory technology that allows for simultaneous chemical and physical characterization and could lead to advances in  materials and drug development.

The technique, which combines the power of atomic force microscopy and mass spectrometry, fills a void and streamlines analytical processes that are vital to science and industry, said Roshan Shetty, chief executive officer of Anasys Instruments. He also noted that the technology improves the current spatial resolution of ambient methods for mass spectrometry imaging by a factor of more than 100, resulting in imaging resolution as small as 250 nanometers, or 1/400th the thickness of a human hair.

“This capability could have a tremendous impact on a broad field of applications in materials and life sciences ranging from single-cell imaging to polymer composites,” Shetty said. [Read more…]
