PNNL Research Highlights

Science at PNNL
  1. Yu, Zhu Research Graced Chemical Communications Back Cover
    Research work by Dr. Xiao-Ying Yu and her team landed on the back cover of the journal Chemical Communications. Yu and Dr. Zihua Zhu of Pacific Northwest National Laboratory (PNNL) in collaboration with Prof. Songqin Liu at Southeast University, China, discovered transient species and reaction pathways not covered in textbooks by employing a true time-resolved chemical imaging technique that has enabled in situ liquid secondary ion mass spectrometry via microfluidics developed at PNNL.
  2. Fredrickson on the “Chemistry of Microbiomes” Seminars
    Microbes make up most of the planet's biomass, living in collaborative communities called microbiomes, which thrive on land, at sea, and within ourselves. They catalyze chemical reactions affecting the health of the Earth's ecosystem and of every human. But many mysteries remain for scientists studying these little worlds of large import.
  3. Article Makes Analyst 2016 ‘Hot Original Research’ List
    A team of researchers at PNNL are warming to the news that a January article of theirs was named to a list of "hot original research articles" of 2016 by Analyst, the journal of the Royal Society of Chemistry. "Hurray," said bioanalytical chemist Erin Baker in an email, "it has been a good week."
  4. A Cooperative Way to Make Ammonia
    Nitrogen is essential for life, but nature's main source of nitrogen is the gas found in our atmosphere - a gas that does not react easily with other elements. Some specialized bacteria turn the air's nitrogen molecules into ammonia so that it can be used to make proteins - the building blocks, machines and power plants of cells. A little over a century ago, chemists developed a way of making ammonia industrially out of atmospheric nitrogen, but the man-made process uses a lot of energy.
  5. New Deep Learning Project Launches at PNNL
    Recently, the U.S. Department of Energy’s Office of Advanced Scientific Computing Research awarded project funding for “Convergence of Deep Learning and Machine Learning for HPC Modeling and Simulation.” Abhinav Vishnu, research scientist with PNNL’s High Performance Computing group, will serve as the project’s principal investigator, overseeing the effort, which will focus on developing extreme-scale Deep Learning algorithms. The project team also includes Charles Siegel (Applied Statistics and Computational Modeling Group) and Jeff Daily, Shuaiwen Leon Song, Joseph Manzano, and Darren Kerbyson (all from PNNL HPC).
  6. Xue-Bin Wang Elected Fellow of American Physical Society
    Congratulations to Dr. Xue-Bin Wang of Pacific Northwest National Laboratory on being elected a Fellow of the American Physical Society (APS) in September of 2016. The number of fellows elected each year is limited to no more than one half of one percent of the total APS membership of 50,000, a clear recognition by peers of his outstanding contributions to physics.
  7. For Targeted Proteomics, a Plugin for Browsing Public Mass Spectrometry Data
    Biologists often envision their hypotheses within a set of protein interactions, networks, and pathways. In turn, their experiments may focus on measuring an explicit subset of these proteins, corresponding to a targeted proteomics experiment.  To date, however, designing a targeted proteomics experiment is very time-consuming, and is typically done only by mass spectrometry specialists.
  8. For NAS, Jansson Weighs in on Microbiomes of the Built Environment
    Microbiologists fervently study the teeming and complex microbiome of both soils and the human gut. But not so much the interiors of the built environment, where most humans spend 90 percent of their time. Homes, hospitals, workplaces, transit systems, and other constructed interior spaces are similarly inhabited by ubiquitous and invisible communities of bacteria, viruses, and fungi.
  9. PNNL to Partner with University of Oregon
    A new agreement between DOE's Pacific Northwest National Laboratory and the University of Oregon will allow scientists, including those working in the catalysis field, to obtain joint appointments that bridge the two research institutions. The agreement paves the way for greater collaboration between the two institutions, which have partnered in the past on numerous projects but never under such a broad agreement.
  10. Imaging Results Are Ones for the Books
    Results: Scientists now have new insights into solid-liquid interface phenomena that go far beyond the textbook description. Researchers at Pacific Northwest National Laboratory developed a way to measure this common electrochemical system interface in place and in real time—a previously impossible task. Their work was showcased in the September 21 issue of Chemical Communications and featured on the journal's back cover.
