Uniform nano-clusters signal improved catalysts

DOE/Pacific Northwest National Laboratory

A new model system of nanostructures has been synthesized and could lead to control of chemical transformations critical for enhancing the nation's energy future.

Structural safety gets boost from new technology

DOE/Pacific Northwest National Laboratory

An acoustic inspection technology developed at Pacific Northwest National Laboratory may help users in the oil, gas and other industries decide if a metal structure can withstand normal operation. Using a newly developed ultrasonic measurement technology, PNNL researcher Paul Panetta and his team can rapidly locate and characterize suspected damage associated with strained metal, which current technologies cannot do.

Sometimes smaller is better

DOE/Pacific Northwest National Laboratory

A research team from the Pacific Northwest National Laboratory, Oregon Health and Science University, University of Minnesota and the University of Idaho is studying the ability of nanoscale iron particles to reduce carbon tetrachloride, a common groundwater contaminant.

Biofuel cells without the bio cells

DOE/Pacific Northwest National Laboratory
Peer-Reviewed Publication

Scientists have observed a first: direct electricity-shuttling from a protein to a mineral. Reporting in the current advance online edition of the Journal of the American Chemical Society, they suggest that proteins -- removed from the outer membrane of a versatile, metal-altering soil bacterium -- could make miniature bioreactor cells feasible. Biologically speaking, the feat is the bacterial equivalent of removing lungs and coaxing the disembodied tissue to breathe.

An infectious agent of deception, exposed through proteomics

DOE/Pacific Northwest National Laboratory
Peer-Reviewed Publication

How Salmonella escapes detection by macrophages, turning predator cells to prey complicit in promoting infection, has seemed impossibly complicated, a needle-in-a-haystack proposition involving thousands of proteins, the building blocks that carry out cells' vital functions. Now, applying the high-volume sorting and analytical power of proteomics -- a detailed survey of microbial proteins present in the 24 hours that follow mouse-macrophage infection -- a team from Pacific Northwest National Laboratory has turned up a suspect protein.

Uniform tungsten trimers stand and deliver

DOE/Pacific Northwest National Laboratory
Peer-Reviewed Publication

Researchers from the Department of Energy's Pacific Northwest National Laboratory, the University of Texas-Austin and Washington State University have developed a new model system that may offer a platform for fundamental reactivity studies of metal oxides used as catalysts in converting hydrocarbons into fuels and value-added chemicals.

Search for natural, safe and abundant chelator may be a 'shell game'

DOE/Pacific Northwest National Laboratory
Peer-Reviewed Publication

The detonation of a suitcase-sized nuclear bomb by a terrorist in a major city would spread toxic material over a wide area exposing humans to various types of radioactive elements. Currently, there are no effective methods to sequester and remove radionuclides from humans in the event of a disaster such as this. Pacific Northwest National Laboratory scientist Tatiana Levitskaia is investigating a unique approach based on a readily available biomaterial that might be used to reduce an individual's radiation dose.

Grant and Award Announcement

Jean Futrell, Battelle Fellow at the Department of Energy's Pacific Northwest National Laboratory, has been chosen to receive the American Chemical Society's Frank H. Field and Joe L. Franklin Award for Outstanding Achievement in Mass Spectrometry. The award will be presented at the ACS national meeting in Chicago in March 2007.

Continuous, real-time analysis of radioactive waste achieved at PNNL

DOE/Pacific Northwest National Laboratory
Peer-Reviewed Publication

An improved monitoring system for providing continuous analysis of high-level radioactive waste has been developed by Pacific Northwest National Laboratory researchers and reported at the national meeting of the American Chemical Society.

Cold shot

DOE/Pacific Northwest National Laboratory
Peer-Reviewed Publication

Scientists have long known that uranium salts under ultraviolet light will glow an eerie greenish-yellow. The resolution of the spectral fingerprint becomes sharper as the temperature falls. Researchers at the Pacific Northwest National Laboratory have now begun to exploit this quirk to hunt for previously hidden uranium in contaminated soils, they report at American Chemical Society national meeting.
