Miaofang Chi of the Center for Nanophase Materials Sciences at Oak Ridge National Laboratory has earned the ORNL Director’s Award for Outstanding Individual Accomplishment in Science and Technology.

ORNL Director Thom Mason presented the award to Chi on Friday during the annual Awards Night event in Knoxville hosted by UT-Battelle, the management and operating contractor for ORNL.

Chi was honored for her pioneering early career research in analytical electron microscopy. Chi’s research has advanced the understanding of defect and interface chemistry and structure and how such defects control materials properties at the atomic level. Her work includes the recent development of transformative insitu microscopy methods to probe transport phenomena at the atomic scale.

Chi also earned the Early-Career Researcher Award. [Read more…]

CVMR President Michael Hargett, left, and Kamran Khozan, chairman and chief executive officer, joined local, state, and federal officials on Friday, March 13, to announce they’re moving company headquarters from Toronto to Oak Ridge, investing $313 million and adding 620 jobs.

 

Tennessee Governor Bill Haslam and Economic and Community Development Commissioner Randy Boyd announced last week that CVMR Corporation is relocating its global headquarters to Oak Ridge from Toronto, Canada. CVMR provides materials for additive manufacturing and announced it will create 620 jobs.

During recruitment of CVMR, University of Tennessee officials assisted the state and hosted the company at UT Knoxville to visit with engineering and chemistry faculty and learn about graduate programs, such as the Bredesen Center for Interdisciplinary Research and Graduate Education, as well as internships and co-ops for students, a press release said. UT System officials provided information about technology transfer, the UT Research Foundation, and Cherokee Farm Innovation Campus. CVMR also learned more about the University’s role in leading the Institute for Advanced Composites Manufacturing Innovation, or IACMI, a $259 million partnership announced by President Barack Obama in January.

Paul Langan, a senior scientist and distinguished research staff member at the U.S. Department of Energy’s Oak Ridge National Laboratory, has been named ORNL’s associate laboratory director for neutron sciences.

Langan will lead the laboratory’s neutron science activities, which include two leading DOE Office of Science user facilities for neutron scattering analysis: the Spallation Neutron Source, or SNS, and the High Flux Isotope Reactor, or HFIR.

“As associate laboratory director, Paul will further broaden our role in neutron sciences globally, expand our instrument capabilities, and prepare for a second target station at the SNS,” ORNL Director Thom Mason said in a press release. [Read more…]

Five Oak Ridge National Laboratory physicists, including Deputy for Science and Technology Ramamoorthy Ramesh, have been named by Thomson Reuters as some of the best and brightest of our time.

The list consists of scientists whose work has been most frequently cited by peers as identified by Thomson Reuters platforms. Citation data was divided into two categories—2002-2012 and 2012-2013—with the latter labeled “hot papers,” ranking in the top 0.1 percent by citations in their field. Seventeen researchers earned this distinction while some 3,200 were included in the second section of the ranking with citations ranking in the top 1 percent for their field and year of publication.

Ramesh, who was actually listed in two categories—physics and materials science—was named to his position at ORNL in June 2013 after serving as the Plato Malozemoff Chair Professor of Materials Science and Engineering and Physics at the University of California, Berkeley, with a joint appointment as a faculty senior scientist at Lawrence Berkeley National Laboratory. He holds a doctorate in materials science from the University of California, Berkeley, and was elected to the National Academy of Engineering in 2011 in recognition of his contributions to the science and technology of functional complex oxide materials.

A small fire in a trash can in a chemistry classroom at Oak Ridge High School on Friday night was the result of an unintended reaction from waste products left over from a chemistry experiment earlier in the day, Oak Ridge Fire Department Chief Darryl Kerley said.

The fire occurred just before 9 p.m. Friday. The classroom was filled with smoke when firefighters arrived, but they were able to use a fire extinguisher to put out the fire in a fire-resistant wastepaper container, which was inside a locked classroom, Kerley said. [Read more…]
