Brown University Reports Advance in Fuel-Cell Technology
[30 Jul 2010 at 12:00pm]
(Electrical Contractor) Creating catalysts that can operate efficiently and last a long time is a big barrier to taking fuel-cell technology from the lab bench to the assembly line. The precious metal platinum has been the choice for many researchers, but platinum has two major drawbacks: it is expensive, and it breaks down over time in fuel-cell reactions. In a new study, chemists at Brown University report a promising advancement. The research team, which includes Brown graduate student and co-author Vismadeb Mazumder and researchers from Oak Ridge National Laboratory in Tennessee, created a 5-nanometer palladium core and encircled it with a shell consisting of iron and platinum....7/29

Reactor restart set for July 28 at ORNL
Four years after a keystroke produced the first neutrons, the Spallation Neutron Source (SNS) has moved into a new phase, both as a neutron research facility and as one of the scientific community's foremost user centers for materials research. "We now have the world's most intense pulsed neutron source, a fact that by itself is very attractive to anybody who wants to use neutrons to investigate materials," says Stephen Nagler, chief scientist of ORNL's Neutron Scattering Science Division. Adding to the facility's appeal is the realization that, with every new operating cycle, the SNS is putting more instruments with brand new capabilities online. Twelve instruments, some as large as houses, are currently available in or adjacent to the mammoth target building, with seven more under construction or in the process of coming online. Users are flocking to the new instruments. Typically, once an SNS instrument becomes available, user requests for research time run about a factor of three greater than the amount of time actually available. Proposals for some of the newer instruments are running six or seven to one.

Opportunities at light source and neutron facilities
New intense sources of radiation at national facilities in Chicago, New York, and Tennessee coupled with the next generation of sensitive detectors are allowing geochemists like John Parise to gather images and data on minerals in one second that would take years of equivalent exposure on conventional laboratory x-ray facilities. John Parise, professor, mineralogist and solid-state chemist at Stony Brook University, New York, discussed this and other new light source systems available to geochemists today at this year's Goldschmidt Conference, hosted by the University of Tennessee, Knoxville, and Oak Ridge National Laboratory. The enhanced power of x-rays and pulsed neutrons -- especially at the new Spallation Neutron Source facility at Oak Ridge National Laboratory -- give geochemists more sensitive tools to detect, characterize and understand the mineral components and the contaminants they absorb or release. Identifying these minerals and how they change with varying conditions such as temperature, relative humidity and irradiation hold the key to understanding the evolution of planetary surfaces, including that of our Earth.

Lithium borate glass for rad detectors
Oak Ridge reseachers are evaluating different types of lithium borate glasses for a couple of projects, including use in radiation detectors for nonproliferation, defense and homeland security applications. According to Lynn Boatner, a group leader ORNL's Materials Science and Technology Division, the detector project is supported by the Defense Threat Reduction Agency (DTRA). Boatner is collaborating with the lab's Zane Bell and Jayson Hayward, who has a joint appointment at ORNL and the University of Tennessee. Boatner said the glasses are made by mixing boron oxide (B2O3) with lithium carbonate, which decomposes in the crucible (at about 1250 degrees) to form lithium oxide and that combines with the boron oxide to form the desired glass. The glasses can be used to detect penetrating radiation via the cerenkov effect, Boatner said. Cerenkov radiation is produced when charged particles are moving faster than the speed of light in a medium, whether it's water or liquid or glass, he said. The cerenkov effect produces the blue glow that one sees in the pool of water that houses the High Flux Isotope Reactor at ORNL.

Study of animal tumors may bring more precision to cancer treatment
Hendrick Construction, Inc. finished a 14,000-square-foot expansion project at Oak Ridge National Laboratory, upgrading lab space at one of the world?s premier research facilities. The Tennessee project created 13 new labs to support scientific research conducted at the Spallation Neutron Source (SNS), the world?s most powerful pulsed source of neutrons for the study of materials. Scientific understanding of the molecular structure of materials is critical to the development of stronger, lighter, and cheaper compounds for a variety of commercial, industrial and other applications.?This was a tough project that was built to exacting specifications in order to provide a flexible research environment,? said Roger Hendrick, president of Hendrick Construction. ?We?re excited to contribute to the growth of this important facility.? The project required the installation of various instruments and controls, as well as complex chemical storage, electrical and ventilation systems. The labs will serve various needs, including X-ray, wet chemistry, magnetic materials characterization, protein crystallography and neutron optics. The flexible space was constructed to adapt to new research needs without additional capital investment. The renovation project is surrounded by other operational space on the second floor of the Spallation Neutron Source Central Lab and Office Building. The project required careful planning and coordination to avoid disruption of ongoing operations and to ensure the work was conducted safely. ?The availability of these new labs will certainly enhance the ability of our neutron scattering user community to perform research at the SNS,? said Oak Ridge National Laboratory Neutron Sciences Director Ian Anderson.

Boosting Batteries For Electric Cars
Gasoline beat out electricity as the prime power source for cars in the early 1900s. The problem was the battery. Electric cars are trying to make a comeback in the early 2000s. The problem is the battery. One excuse: "In energy storage, we have a much bigger problem," says Claus Daniel, a research scientist and project director in the materials science and technology division at Oak Ridge National Laboratory. Oak Ridge happens to have a contraption that can see where others can't. It's the world's brightest source of neutrons, called the Spallation Neutron Source. It speeds protons to 90% of the speed of light and smashes mercury atoms to break off neutrons. Beams of neutrons can then be directed at materials, including whole working batteries, where they penetrate deep into their targets. The way the neutrons bounce off atoms inside tells researchers what is going on in there. As they understand better, they may be able to tweak the chemistry to make the battery last longer. "It will give us totally new insight into what's going on in the inside of a battery," says Daniel. "The level of detail you can see is eye-opening."
