APS Articles in Frontiers 2001
Frontiers was the annual publication of Argonne research highlights. This page contains Frontiers articles focusing on APS-related research.
Brilliant X-Rays Reveal the Unknown
Discoveries at Argonne's Advanced Photon Source (APS) over the past year have ranged from new insights into the human immune system to detection of an ancient forgery (see separate stories). more >>
Finding Fine Fields Could Mean Major Magnetic Manipulation
The
ability of metal oxides to change electrical resistance in the presence
of a magnetic fielda process called magnetoresistancehas long fascinated
researchers. One group of metal oxides, manganese oxides, is of particular
interest because its members exhibit colossal magnetoresistancea dramatic
increase in electrical conductivity under a magnetic field. more >>

Show How the Immune System Recognizes an Enemy
Clues to how the immune system identifies enemy threats may lead to new ways
to prevent some diseases. Researchers from the Dana-Farber Cancer Institute,
the Harvard Medical School and Argonne examined key immune system cells, using
Structural Biology Center instruments at the Advanced Photon Source. The APS
provides the nation's most brilliant light for X-ray crystallography, a process
that allows three-dimensional imaging of changes in crystals as they occur. more >>

Light Up the Future of Synchrotron Light Sources
Argonne's Advanced Photon Source (APS) is a third-generation
synchrotron light source that currently produces the nation's
most brilliant X-ray beams for studies in materials science,
biological and environmental research. However, looking toward
the future, the APS is also a leader in developing the technology
for the next leap in X-ray brilliance, a new "fourth generation" of
powerful synchrotron radiation light sources capable of producing
hard X-raysthose with the highest energy and most penetrating
powerwith a peak brilliance billions of times greater than currently
available anywhere in the world. more >>
Modern Machine Solves Old Mystery: Metal “Fingerprint” Reveals Genuine Artifact
Innovative 21st century technology recently transported scientists and historians
back to the 16th century in a search for truth. Argonne's Advanced Photon
Source (APS) is able to reveal an object's composition, crystal structure
and thickness without damaging the object. more >>
Protein
Structures Solved Faster with More Detail than Ever
As scientists across the country finished "mapping" the human genome, Argonne
researchers were already fine-tuning the technology to meet the next hurdle-slashing
the time needed to determine the genome's three-dimensional structure. more >>
Surface Studies of Minerals Reveal Insight into Cleaning Contaminated Environments
Finding solutions to large-scale environmental problems often requires researchers
to start small microscopically small. By studying the interactions of
fluids with mineral surfaces at the molecular scale, Argonne scientists
hope to learn more about larger-scale environmental processes. The interactions
of mineral surfaces and fluids are crucial to the weathering of rocks,
the formation of ore deposits and petroleum reservoirs, soil formation
and plant nutrition, and the transport of contaminants through groundwater
aquifers. more >>
