Scientist wins energy award at technology event
Xin Zhao has won a World Technology Network award in the individual Energy category for innovative work of "the greatest likely long-term significance" in his field. Zhao designed and patented a supercapacitor that would use graphene. The invention could someday see batteries in electric vehicles and similar devices boosted or replaced by high-power, high-capacity, fast-charge/discharge energy storage systems using graphene.

Building block detectors for plants
While a plant's overall health can often be determined through simple observation, researchers sometimes need to see what's happening on the inside. That's where Jefferson Lab group leader Drew Weisenberger and his colleagues come in. They are working to develop tools that can image inside plants.

Argonne scientist energizes quest for lost Leonardo da Vinci painting
Perhaps one of Leonardo da Vinci's greatest paintings has never been reprinted in books of his art. Known as the "Battle of Anghiari," it was abandoned and then lost -- until a determined Italian engineer gave the art world hope that it still existed, and a physicist from the US Department of Energy's Argonne National Laboratory developed a technique that may reveal it to the world once again.

Simulating turbulent combustion speeds design of power and propulsion devices
A team led by mechanical engineers Joseph Oefelein and Jacqueline Chen of Sandia National Laboratories simulates turbulent combustion at different scales. Chen and Oefelein were allocated 113 million hours on Oak Ridge Leadership Computing Facility's Jaguar supercomputer in 2008, 2009 and 2010 to simulate autoignition and injection processes with alternative fuels. For 2011 they received 60 million processor hours for high-fidelity simulations of combustion in advanced engines.

A catalyst for high-impact science
A multi-institutional team of scientists is using EMSL's new Recovery Act-funded capabilities to achieve new insights into catalytic reactions on the surfaces of advanced metal oxide-based materials. The work is part of an inaugural EMSL Research Campaign that brings together world-leading capabilities and expertise in support of more efficient, less costly catalysts -- a need with cross-cutting energy and industrial applications.

Tribal schools create their own biodiesel to win energy challenge
Last year, American Indian tribal colleges and high schools competed to build the best wind turbine; this year, their challenge was different, but still related to renewable energy -- creating biodiesel fuel out of raw biomass.

Breakthrough fusion simulations shed light on plasma confinement
A research team led by William Tang of the Department of Energy's Princeton Plasma Physics Laboratory is developing a clearer picture of plasma confinement properties in an experimental device that will pave the way to future commercial fusion power plants. Over the past three years using resources of the Argonne Leadership Computing Facility and Oak Ridge Leadership Computing Facility, Tang's team has made continual improvements to tools essential for computationally solving fusion problems.

Result tickler: Lead nucleus may bury positive side under neutral facade
Results from the Lead (Pb) Radius Experiment (PREx), performed last year at Jefferson Lab, suggest that the nucleus of a lead atom buries its positive "personality" beneath a neutral exterior. The preliminary result is consistent with the idea that neutrons form a kind of "neutron skin" around the protons in the nucleus in heavy nuclei. It is important for understanding heavy nuclei and for theoretical equations that describe the life cycles of neutron stars.

Supercomputers aid in understanding the basic building blocks of nature
A team of scientists collaborating under the leadership of Paul Mackenzie of Fermi National Accelerator Laboratory has been awarded a total of 80 million processor hours at the Oak Ridge Leadership Computing Facility and the Argonne Leadership Computing Facility for quantum chromodynamics research to help develop a unified theory of how the four forces interact. Physicists believe that more fundamental interactions must unite the presently observed forces.

Turning data into wild rides through dark domes
Thanks to scientists at SLAC and Stanford, planetarium audiences can fly through an increasingly realistic cosmos. A show now playing in San Francisco is a case in point. Unlike shows of a decade ago, all the animations are based on real scientific data including visualizations made by researchers at KIPAC, the Kavli Institute for Particle Astrophysics and Cosmology.

It takes 3 to tango
Researchers who want to understand how and why a nucleus hangs together as it does must take into account the complex interactions known as the three-body force. This conclusion, drawn from simulations on America's most powerful supercomputer, is outlined in the May 20, 2011, edition of Physical Review Letters.

Odd particle left out in the cold
The old saying birds of a feather flock together may also be true for the smallest bits of matter. According to a study recently published in Physical Review Letters, like particles inside protons and neutrons band together, leaving the odd one out.

Packing the ions
Drexel University's Yury Gogotsi and colleagues recently needed an atom's-eye view of a promising supercapacitor material to sort out experimental results that were exciting but appeared illogical. That view was provided by a research team led by Oak Ridge National Laboratory computational chemists Bobby Sumpter and Jingsong Huang and computational physicist Vincent Meunier.

The curious case of germanium-72
Physicists from Oak Ridge National Laboratory, the University of Tennessee, and Germany's GSI in Darmstadt recently used ORNL's Jaguar supercomputer to explore the pair bonding of neutrons in one uncommon isotope -- germanium-72. In doing so they discovered that changes in temperature and rotation take the nucleus through at least two physical phases.
