Wiley Postdoctoral Fellowship. The position closes Nov. 30. The recipient will serve a one-year term, with the possibility of the fellowship being renewed for a total of three years. The position includes an annual salary of $70,000, and an additional $20,000 may be made available for research support and travel. http://www.pnnl.gov/contacts/staffinfo.asp?uid=7DEE44114B8CF4429416592810EA78AA http://imaging.pnnl.gov/ Nanoparticles hundreds times smaller than the width of a hair are more and more a part of people's daily lives. Used in everything from car coatings to clothes to cosmetics, little is known about their safety in the environment. Chemist Robert Hamers at the University of Wisconsin-Madison is leading a multi-institutional effort to gain new understanding about nanomaterials, especially how they get into cells and tiny organisms such as those found in freshwater lakes. Pacific Northwest National Laboratory's Galya Orr has been using and improving high resolution microscopy at EMSL via PNNL's Chemical Imaging Initiative. Orr will be applying the expertise she's gained from studying how nanoparticles enter lung cells found lining our airways. http://www.pnnl.gov/contacts/staffinfo.asp?uid=7DEE44114B8CF4429416592810EA78AA http://imaging.pnnl.gov/ Anyone who owns an electronic device knows that lithium-ion batteries could work better and last longer. Now, scientists examining battery materials on the nano-scale reveal how nickel forms a physical barrier that impedes the shuttling of lithium ions in the electrode, reducing how fast the materials charge and discharge. Published last week in Nano Letters, the research also suggests a way to improve the materials. http://www.pnnl.gov/contacts/staffinfo.asp?uid=7DEE44114B8CF4429416592810EA78AA http://imaging.pnnl.gov/ Congratulations to <a href="http://www.emsl.pnl.gov/news/viewArticle.jsp?articleId=395">Dr. Ajay Karakoti!</a> He garnered the honor in recognition of his "insightful and creative contributions to the visualization of functionalized nanoparticle surfaces," said Robby Robinson, chair of the award selection committee. The committee noted Karakoti demonstrated EMSL's interdisciplinary research focus by applying his scientific inquiry to biology, toxicity, materials science, chemistry, and physics by the careful and meticulous characterization of nanomaterials. http://www.pnnl.gov/contacts/staffinfo.asp?uid=7DEE44114B8CF4429416592810EA78AA http://imaging.pnnl.gov/highlights/ Congratulations to the team from Pacific Northwest National Laboratory and Hummingbird Scientific on receiving a Microscopy Today 2012 Innovation Award. The award honors groundbreaking imaging products and methods. The honorees are Jun Liu, Chongmin Wang, Don Baer, Suntharampillai (Theva) Thevuthasan, Wu Xu and Jiguang (Jason) Zhang from PNNL; and Daan Hein Alsem and Norman Salmon from Hummingbird Scientific http://www.pnnl.gov/contacts/staffinfo.asp?uid=7DEE44114B8CF4429416592810EA78AA http://imaging.pnnl.gov/highlights/ It's been said, build a better mousetrap and the world will beat a path to your door. When it comes to energy issues, <a href="http://www.emsl.pnl.gov/news/viewArticle.jsp?articleId=390">building a better battery could bring the world to your door.</a> building a better battery could bring the world to your door. Using resources at EMSL, imaging scientists are committed to improving electrochemical energy storage devices. Today's devices are not powerful enough, require frequent recharging, have to be periodically replaced, and are expensive to produce. To help solve these problems and others, scientists need to understand how batteries work and why they gradually wear out. http://www.pnnl.gov/contacts/staffinfo.asp?uid=7DEE44114B8CF4429416592810EA78AA http://imaging.pnnl.gov/highlights/ Once impossible, scientists can now eavesdrop on microbes, thanks to a new technique from scientists at Pacific Northwest National Laboratory and three universities. Microbes converse by releasing simple and complex molecules, called metabolites. The metabolites interact with and alter their environment and nearby cells. To listen in, the team combined nanospray desorption electrospray ionization mass spectrometry, or nanoDESI, and a new bioinformatics technique. http://www.pnnl.gov/contacts/staffinfo.asp?uid=7DEE44114B8CF4429416592810EA78AA http://imaging.pnnl.gov/highlights/ An exciting and novel technique now allows researchers to characterize, with high sensitivity and in time and space, the metabolite profile of living microbial communities grown on a soft agar surface. http://www.pnnl.gov/contacts/staffinfo.asp?uid=7DEE44114B8CF4429416592810EA78AA http://imaging.pnnl.gov/highlights/ Lithium ion batteries drive devices from electric cars to smartphones. And society is demanding more batteries with more capacity from each battery. To help meet this demand, EMSL users and researchers put their energy behind a clever new idea that, literally, gives batteries a bit of room to grow. http://www.pnnl.gov/contacts/staffinfo.asp?uid=7DEE44114B8CF4429416592810EA78AA http://imaging.pnnl.gov/highlights/ It's sort of a pop-culture cliche: a scientist or scientific team pours heart, soul, and countless hours into a project-nearly to the point of obsession--until The Moment arrives. The first result comes; the instrument works; the data make sense; the code does its job. Whatever the exact fabric of The Moment, it's exactly what the scientist was hoping for--or it's unexpected in an even more interesting way. http://www.pnnl.gov/contacts/staffinfo.asp?uid=7DEE44114B8CF4429416592810EA78AA http://imaging.pnnl.gov/highlights/ Nigel Browning Named as Wiley Research Fellow: Congratulations to Dr. Nigel Browning, Pacific Northwest National Laboratory's Chief Scientist for Chemical Imaging and world-renowned scientist in materials physics, on being selected as a William R. Wiley Research Fellow at the Department of Energy's EMSL. Browning was selected based on recognition of his strong contributions to the microscopy capabilities and research at the user facility. http://www.pnnl.gov/contacts/staffinfo.asp?uid=7DEE44114B8CF4429416592810EA78AA http://imaging.pnnl.gov/cii_staff.stm Pacific Northwest National Laboratory, Lawrence Berkeley National Laboratory, Argonne National Laboratory, University of Washington, Advanced Photon Source, Argonne National Laboratory, Yeshiva University, Brookhaven National Laboratory, University of New Mexico, Foundation for Fundamental Research on Matter, University of California, San Diego. http://www.pnnl.gov/contacts/staffinfo.asp?uid=7DEE44114B8CF4429416592810EA78AA http://imaging.pnnl.gov/thrustareas/ The Chemical Imaging Initiative sponsors thrust areas to develop new capabilities. http://www.pnnl.gov/contacts/staffinfo.asp?uid=7DEE44114B8CF4429416592810EA78AA http://imaging.pnnl.gov/seminars/ Past And Future Speakers Listing - 2012 - 2011 Frontiers in Chemical Imaging. http://www.pnnl.gov/contacts/staffinfo.asp?uid=7DEE44114B8CF4429416592810EA78AA http://imaging.pnnl.gov/presentations/index.stm#cis2012 Sharing new information and new ideas across the scientific community is an important part of Pacific Northwest National Laboratory's chemical imaging research.
