Argonne News is the Argonne weekly employee newsletter. This page contains Argonne News articles that focus on the APS.

 

Metal atoms near the surface of a liquid alloy arrange themselves in alternating layers one atom thickMixed metals not so mixed up at the nano-level (Nov. 25)
With the help of the Western Hemisphere's most brilliant hard X-ray beams at the Advanced Photon Source, scientists have seen for the first time metal atoms near the surface of a liquid alloy arrange themselves in alternating layers one atom thick.

Argonne researchers discover keys to improving commercial magnet technology (Nov. 18)
Permanent magnets are important in a broad variety of commercial technologies, from car starters to alternators for wind power generation to computer hard drives. Researchers at the U.S. Department of Energy's Argonne National Laboratory have found new clues to making those magnets longer-lasting and more powerful.

Aerial view of the Advanced Photon Source.Stable, bright X-ray beam provides better data (Sept. 30)
What a difference a decade makes. Ten years ago the Advanced Photon Source (APS) produced its first light. Since then the APS has focused on continuous improvement to provide the best beamlines for science research. Its accelerator physicists pioneered a technique called "top-up" to replenish the particle beam for optimal beam performance. Today, the APS provides the most brilliant X-ray beams in the world for research, and the beams are extremely stable and reliable.

A researcher teaches students about computed microtomographyStudents fill summer days with intensive X-ray and neutron school (Sept. 2)
Each year as many as 200 students in Ph.D. programs compete to attend Argonne's National School on Neutron and X-ray Scattering. For the talented 60 selected to attend the school here each August, it means two weeks of 10-12 hours a day, six days a week.

P5CR structure from Streptococcus pyogenesMidwest Center for Structural Genomics: Filling the structural biology pipeline (Aug. 19)
Faster, easier-to-use X-ray beamlines, such as those operated by the new GM/CA CAT, are allowing researchers to increase the pace of determining atomic structures of biomolecules important to life. This structural information will help reveal the roles that proteins play in health and disease and lead to structure-based medicines and therapies to treat genetic and infectious diseases.

HK97 VIRUS A group from Scripps Research Institute used the GM/CA CATs narrow beam to get more precise data from a crystal of the HK97 virus as it undergoes a stages assembly process.Split beamlines can double research capacity at Advanced Photon Source (Aug. 19)
A new beamline dedicated this summer at the Advanced Photon Source (APS) sets a new standard for structural biology research at synchrotrons. The GM/CA CAT facility exploits the latest technology to double the number of beamlines and create finer X-ray beams to capture data from hard-to-study biomolecules.

WINNING TEAM – The award-winning X-ray lenses were created in this lab. The developers and customers are pictured clockwise, from front center: Al Macrander, Chian Liu, Jörg Maser, Ray Conley, Brian Stephenson and Hyon Chol Kang.Argonne wins four R&D 100 Awards for scientific, technological innovation (Jul. 8)
Advances in technology ranging from help for victims of Parkinson's disease and epilepsy to more efficient combustion in industrial furnaces are likely with award-winning research at the U.S. Department of Energy's Argonne National Laboratory and its partners.

 

PROTEIN STRUCTURE – This image sows the structure of a protein from a pro-phage integrated into genome of Bacillus cereus. The function of the protein is unknown, but the structure suggests that it may be involved in DNA binding or transfer. The protein structure was determined at the Midwest Center for Structural Genomics by Rongguang Zhang and Grazyna Joachimiak.$50 million grant will aid studies of protein structures (Jul. 1)
Proteins are the molecular machines that make growth possible, and understanding their structure is key to developing pharmaceuticals, A new window to that understanding is being made possible under a $50 million grant to the U.S. Department of Energy's Argonne National Laboratory.

Argonne scientists receive distinguished performance award (Jun. 16)
Five scientists from the U.S. Department of Energy's Argonne National Laboratory have received the 2005 University of Chicago Board of Governors for Argonne Distinguished Performance Award, which recognizes outstanding scientific or technical achievements or a distinguished record of achievements.

Argonne to receive $2.3 million for basic research on fuel cell catalysts (Jun. 20)
The funding, from the U.S. Department of Energy's Office of Basic Energy Sciences, will be used to study the molecular basis of catalysis, with a particular interest in the oxygen reduction reaction in fuel cells.

Argonne holds cornerstone ceremony at new Center for Nanoscale Materials (May 6)
More efficient energy transmission and implantable devices that automatically sense drug levels and administer drugs are just two examples of the benefits of research that may result from work at the new Center for Nanoscale Materials, under construction at the U.S Department of Energy's Argonne National Laboratory.

The nano-revolution continues at Argonne (Apr. 29)
Illinois Gov. Rod Blagojevich, U.S. Rep. Judy Biggert and Energy Secretary Samuel Bodman participated in a May 6 cornerstone-laying ceremony for the Center for Nanoscale Materials (CNM) at Argonne National Laboratory.

SELF-ASSEMBLING CAGE – These self-assembling hollow spheres may contain actinides or other elements, such as potassium.New materials provide insight into radioactivity in the environment, self-assembling nanostructure (Feb. 18)
A new class of materials that could enhance basic understanding of how radioactive materials behave in the environment has been discovered by researchers from the University of Notre Dame and Argonne National Laboratory. Called actinyl peroxide compounds, these materials self-assemble into nano-sized, hollow cages that could have useful new electronic, magnetic and structural properties important to the emerging world of nanotechnology.

X-ray movie of insect flight.X-ray movies reveal insect flight, muscle motion (Jan. 21)
Watching flies fly may not seem like high-tech science, but for researchers using the Western Hemisphere's most brilliant X-rays, located at the Advanced Photon Source at the U.S. Department of Energy's Argonne National Laboratory, it not only helps explain how insects fly but also may someday aid in understanding human heart function.
