Kerstin Kleese van Dam
Kerstin Kleese van Dam Authors Big Data Article
The Multimodal Analysis and Integration Framework for Chemical Imaging lead at Pacific Northwest National Laboratory, Dr. Kerstin Kleese van Dam wrote about the need for in-situ management and analysis of massive experimental data sets in Datanami. The Rapid Experimental Analysis Framework and Component Library, REXAN, is discussed. Developed through the Chemical Imaging Initiative, REXAN provides a library of analytical components for essential actions, including compressions, feature detection and visualization. In the future, Kleese van Dam expects to see a publically available REXAN repository with open-source and proprietary components that allow scientists to build near-real-time analysis tools.
Sotiris Xantheas' Work Highlighted in Chemical & Engineering News
Research by Dr. Sotiris Xantheas at Pacific Northwest National Laboratory on how the classic SN2 bimolecular nucleophilic substitution reaction, a reaction of fundamental importance in organic chemistry, is halted in the gas phase by just two or three water molecules was highlighted in a 2-page story in Chemical & Engineering News, February 25. The reaction exchanges atoms or functional groups attached to an electron-deficient carbon center. The reaction works well in organic solvents, but not in water. Xantheas and his colleagues at Hiroshima University, in a Communication which will appear in the Angewandte Chemie International Edition, combined theory and experiment to gain a molecular-level understanding of how the water stops the reaction.
Morris Bullock Named Geek of the Week
Center for Molecular Electrocatalysis Director Dr. R. Morris Bullock was selected as Geek of the Week. Bullock was chosen for this honor for his foundational research in affordable, earth-abundant catalysts. You can learn more about Bullock's inspirations, aspirations and role models in GeekWire's article.
Dick Smith interviewed for R&D Magazine
R&D Magazine explores systems biology with Pacific Northwest National Laboratory's Dr. Richard (Dick) Smith and other former scientists of the year in the article "Beyond the Genome," published February 26. Smith, who is a Battelle Fellow and Director of Proteome Research at PNNL, was the magazine's 2010 Scientist of the Year, selected for his pioneering work in effectively combining the development of new technology with its application to biological systems to gain new insights.
New AAAS Fellows Honored

L. Ruby Leung Quoted in Science
Dr. L. Ruby Leung, atmospheric scientist at Pacific Northwest National Laboratory, was quoted in a Science magazine News & Analysis article about global and regional modeling. The article describes a recent study by climate modelers to gauge the effectiveness of regional models to predict regional change. Leung, a world-renowned leader in regional climate modeling, is co-principal investigator of the North American Regional Climate Change Assessment Program, which recently evaluated temperature and precipitation results from six regional climate models over a 30-year period.

Ben Kravitz Quoted in The Chronicle of Higher Education
Dr. Ben Kravitz, atmospheric postdoctoral researcher at Pacific Northwest National Laboratory, was quoted in "As Temperatures Keep Rising, Geoengineering Gets a Closer Look" published in the January 28th edition of The Chronicle of Higher Education. The Chronicle is a publication for college and university faculty members and administrators. Kravitz was sought after for his expertise on the impacts of climate engineering techniques. The article features the topic of geoengineering, including Kravitz's comment regarding the use of iron sulfate to grow phytoplankton in the Pacific Ocean. This research has implications for climate warming.
Evgueni Kassianov Aerosol Research Featured in Eos Research Spotlight
Dr. Evgueni Kassianov, atmospheric scientist at Pacific Northwest National Laboratory, was lead author on a publication chosen for a January 15 Eos "Research Spotlight." Eos, a newsletter for members of the American Geophysical Union, highlights selected new research from all of the AGU journals. The spotlight features Kassianov's research published in the journal Geophysical Research Letters, concerning the unexpected role of large, "coarse-mode" aerosols in relatively clear-sky conditions. The research has implications for calculating the effects of these sunlight-scattering particles on the Earth's energy budget. For more on this research, see "Invisible Giants in the Sky"
