Brookhaven National Laboratory and collaborators win R&D 100 Award

DOE/Brookhaven National Laboratory
Grant and Award Announcement

The U.S. Department of Energy's Brookhaven National Laboratory and National Renewable Energy Laboratory (NREL), along with industrial partners Bob Curran & Sons and Ticona Corporation, have won a 2002 R&D 100 Award for developing a smart, high-performance coating. This polyphenylenesulfide (PPS) coating system is particularly suited for use in carbon-steel heat exchanger tubes in geothermal power plants.

Physicists announce latest muon g-2 measurement

DOE/Brookhaven National Laboratory
Peer-Reviewed Publication

Scientists today announced their latest result from a ground-breaking experiment dubbed muon g-2, a precision measurement of the anomalous magnetic moment of the muon. The new measurement, based on data collected in 2000, directly confronts the so-called Standard Model of particle physics and strengthens scientists' confidence in a previous measurement reported by the same group in February 2001 (based on data collected in 1999).

Scientists determine age of New World map

DOE/Brookhaven National Laboratory
Peer-Reviewed Publication

Scientists from the University of Arizona, the U.S. Department of Energy's Brookhaven National Laboratory, and the Smithsonian Institution have used carbon-dating technology to determine the age of a controversial parchment that might be the first-ever map of North America.

Nanoscale crystallography reveals hidden structural details

DOE/Brookhaven National Laboratory
Peer-Reviewed Publication

Scientists from the U.S. Department of Energy's Brookhaven National Laboratory and Michigan State University have just demonstrated a technique that allows them to decipher fine-level nanoscale structures. Structural information may one day lead to tailoring nanoscale properties for useful applications.

Scientists create new material with varying densities of gold nanoparticles

DOE/Brookhaven National Laboratory
Peer-Reviewed Publication

For the first time, scientists have created a material with a gradient of gold nanoparticles on a silica covered silicon surface using a molecular template. The material provides the first evidence that nanoparticles -- each about one thousand times smaller than the diameter of a human hair -- can form a gradient of decreasing concentration along a surface, which may be useful for applications in making better filters, more efficient sensors, and faster catalysts.

Air quality study focuses on New England

DOE/Brookhaven National Laboratory

In an effort to identify why the Northeastern US has some of the worst air quality in the country, NOAA's largest research vessel, along with the Department of Energy's Gulfstream research aircraft, will monitor air pollutants and their transport in the region this summer.

More clues about obesity revealed by brain-imaging study

DOE/Brookhaven National Laboratory

The idea that obese people eat too much because they find food more palatable than lean people do has gained support from a new brain-imaging study at the U.S. Department of Energy's Brookhaven National Laboratory. The study reveals that the parts of the brain responsible for sensation in the mouth, lips, and tongue are more active in obese people than in normal-weight control subjects.
