Illinois provides $17 million for Nanocenter Artist's conception of Center for Nanoscale Materials
The CNM is one of five centers for nanoscale research being built at Department of Energy national laboratories. Expected to be completed in Winter 2005-2006, CNM's building is to abut the Advanced Photon Source near a specially designed hard X-ray nanoprobe beamline that will permit scientists to study structures as small as 30 nanometers (30 billionths of a meter) in size, using advanced diffraction, spectroscopy and imaging techniques.

X-rays penetrate secrets of diesel combustion A scientist peers through a port in fuel injection chamber
For the first time ever, scientists are using X-rays to penetrate diesel fuel injector sprays to improve combustion. The Argonne team has uncovered an unexpected shockwave in the gas spray as well as other data that may help manufacturers build cleaner, more efficient engine-injection systems.

The team, made of Jin Wang of the Experimental Facilities Division and Steve Ciatti, Christopher Powell and Yong Yue of the Energy Systems Division, won the U.S. Department of Energy 2002 National Laboratory Combustion and Emissions Control R&D Award.

Insect breathing mechanism discovered Image of wood beetle
A Surprising new insect breathing mechanism similar to lung ventilation in vertebrates has been discovered by scientists at Chicago's Field Museum and Argonne.

The discovery of this fundamental aspect of respiratory biology for insects could "revolutionize the field of insect physiology," says Mark Westneat, associate curator of zoology at The Field Museum.

Insects - the most numerous and diverse group of animals- don't have lungs. Instead, they have a system of internal tubes called tracheae that exchange oxygen through slow, passive mechanisms, including diffusion. But this study demonstrates that beetles, crickets, ants, butterflies, cockroaches, dragonflies and other insects also use rapid cycles of tracheal compressions and expansion in their head and thorax to breathe.

The results of the research, performed at the Advanced Photon Source (APS) at Argonne, have been published in the journal Science.
