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.

Transparent batteries: Seeing straight through to the future?
SLAC and Stanford researchers have invented a transparent lithium-ion battery that is also highly flexible. It is comparable in cost to regular batteries on the market today, with great potential for applications in consumer electronics.

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.

Buried treasure
EMSL scientist Hongfei Wang and his team recently struck a vein that could lead to research gold for scientists interested in molecular interactions at interfaces. Their picosecond-femtosecond broadband sum frequency generation system is now ready to provide a new generation of surface vibrational spectroscopy and imaging.

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.

Solar and hydrogen car races spark imaginations
Fun and enthusiasm fuel competitions that are among the educational tools NREL and DOE provide to encourage students to pursue science.

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.

Chemistry and materials simulations speed clean energy production and storage
Catalysts are just one area of investigation for a multi-institutional team whose 70 publications in 3 years detail prodigious scientific output from the world's fastest chemistry simulations. "Our long-term goal is enabling the design of new generations of clean and sustainable technologies to produce, transmit, and store energy," said team leader Robert Harrison, a computational chemist at Oak Ridge National Laboratory.

INL wind researchers test cool way to stretch capacity of existing power lines
Some Idaho National Laboratory wind power researchers think we can move more electricity through the transmission lines we already have without breaking the bank.

Students learn about wind power first-hand through Wind for Schools program
For years, Jenny Christman tried to find a way to get a wind turbine to educate the students at Northumberland Middle and High School about wind power. Now, with help from the Wind for Schools project and the Virginia Center for Wind Energy at James Madison University, the students at Northumberland are learning about wind power first-hand from the newly constructed turbine at their school.

Neutrons 'go viral' at ORNL
A research team from ORNL and North Carolina State University is using small angle neutron scattering to study how viruses change their structure when they move between different host species. Understanding how a virus reorganizes itself when it goes from a mosquito to a human is critical for the development of medicines that can block the spread of viruses.

Berkeley Lab scientist walks the walk -- produces more electricity than he consumes
Energy management engineer Steve Greenberg bikes three miles uphill to work every day, rain or shine. He refuses to use a desktop computer, insisting on a less energy-intensive laptop. And to avoid using paper towels each time he visits the bathroom, he keeps a hand towel in his office. Those are only a few of the things he does to reduce his carbon footprint�and that's just at work.

A research team led by Peter C. Lichtner of Los Alamos National Laboratory is using the Oak Ridge Leadership Computing Facility's Jaguar supercomputer, located at Oak Ridge National Laboratory, to build a 3-D model of an underground uranium waste plume at the Hanford Site's 300 Area. A better understanding of the underground migration properties of uranium, which has infiltrated the Columbia River, may aid stakeholders in weighing options for contaminant remediation.
