Materials modeling shows big future for boron nitride nanoribbons
Alejandro Lopez-Bezanilla at Oak Ridge National Laboratory studies a proposed graphene substrate: boron nitride. Graphene, which is carbon in the form of freestanding 1-atom-thick sheets, is a natural for next-generation computer chips, communications equipment, and solar energy devices. Electrons flow through the material at an astonishing 1 million meters per second. To live up to its potential, however, graphene needs support. On its own, its edges wrinkle, tear, or roll up.

'Colony' software speeds up high-performance computing processes
As the number of processors continues to increase in leadership-class supercomputers, their ability to perform parallel computation -- doing multiple calculations simultaneously -- becomes increasingly important. The surge in machine size and complexity has led the Oak Ridge Leadership Computing Facility computer scientists to try new and interesting strategies to keep large systems running at the highest efficiency. Their efforts have nearly tripled performance for synchronizing collective operations.

Researchers show how proteins help DNA replicate past a damaged site
A multi-institutional research team led by Ivaylo Ivanov of Georgia State University has employed the Jaguar XT4 supercomputer at Oak Ridge National Laboratory and X-rays a billion times brighter than the sun, produced at Lawrence Berkeley National Laboratory, to illuminate how DNA replication continues past a damaged site so a lesion can be repaired later. The results appear in the Oct. 17, 2011, online issue of Proceedings of the National Academy of Sciences.

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.

Supercomputers and airplanes help model hurricane structure and intensity
Information from major hurricanes such as Katrina is being put to good use by scientists striving to understand how hurricanes intensify. A research team led by Jon Reisner of Los Alamos National Laboratory is employing the Oak Ridge Leadership Computing Facility's Jaguar supercomputer to use data from lightning detectors and even wind instruments mounted on planes flown into the eye of a hurricane to improve atmospheric models. These simulations may lead to more accurate prediction of hurricane intensities.

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.

Creating order from chaos at the LCLS
In the world of physics, where everything tends toward disorder, researchers working on the Linac Coherent Light Source are seeking perfect order. Many experiments at the pioneering machine will require each molecule in a puff of gas to align with all of the others, creating a uniform field of molecules on which tests can be conducted.

A robot called WANDA
Berkeley Lab scientists have established a revolutionary nanocrystal-making robot, capable of producing nanocrystals with staggering precision. This one-of-a-kind robot, named WANDA, provides colloidal nanocrystals with custom-made properties for electronics, biological labeling and luminescent devices. Since this robot is controlled by software protocols, novice users can direct WANDA to perform complex workflows that traditionally require extensive chemistry experience.

Lab enhances scientific data sharing with cutting-edge connection
In early 2005, researchers affiliated with Hall B wanted to transfer raw data from a recent experiment from the tape silo to computers offsite -- a task that without interruption would have taken the Lab's existing network connection almost seven days. Jefferson Lab's newly upgraded network connection is able to transfer data at a rate of up to 10 Gigabits per second, so that same transfer can now be completed in just 2.5 hours.

ScalaBLAST solves problems in record time
Scientists are dedicated to making discoveries that influence our world, but making these discoveries takes time. It took Albert Einstein 16 years to express his general theory of relativity. Benjamin Franklin was first introduced to electricity experiments on a trip to Boston in 1746, but his famous lightning rod experiment didn't occur until six years later -- and he knocked himself unconscious more than once in the process.

Jefferson Lab's newest cluster computer takes shape
Unlike a regular computer -- whose "brain" consists of one or perhaps two processors -- a cluster computer's brain can contain hundreds or even thousands of individual processors, called nodes -- all wired together. To solve a problem, the cluster splits the problem into parts, and each node computes its designated part and shares the result with other nodes to produce the final solution.

NVAC: Visualizing a safer homeland
September 11, 2001 forever changed how Americans view national security. The responsibility for protecting citizens from future attacks has fallen on government shoulders in an increasingly discontented world. One way the Department of Homeland Security has responded is with new visual analytic technologies that transform volumes of documents, emails, images, videos and voice recordings into interactive visuals.
