Science at PNNL
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.
Fredrickson on the Chemistry of Microbiomes Seminars
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.
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."
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.
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).
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.
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.
For NAS, Jansson Weighs in on Microbiomes of the Built Environment
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.
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.
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.
