Is Graphite a Diamond’s Best Friend? New Information on Material Transformation (Nov. 18)
Diagram of a typical diamond anvil cell configurationScience has yet to achieve the alchemist’s dream of turning lead into gold. But a group of re-searchers using the GeoSoilEn-viroCARS (GSECARS) and High-Pressure Collaborative Access Team (HP-CAT) facilities at the Department of Energy’s Advanced Photon Source (APS) at Argonne National Laboratory, may have found a way to turn ordinary soft graphite (source of the “lead” found in pencils) into a new, super-hard material that “looks” just like diamond.

The $5.9-million, 2.75-year NNSA grant to the Geophysical Laboratory of the Carnegie Institution in Washington, D.C., under the Stewardship Science Academic Alliances program, will fund research into the behavior of materials under extreme pressure conditions at the Carnegie/Department of Energy Alliance Center (CDAC).

Schematic of the powder diffractometer setup.Dedicated APS Powder Diffraction Beamline Funded by DOE-BES (Jul. 23)
A new high-resolution powder diffractometer beamline will be funded by the U.S, Department of Energy's Office of Basic Energy Sciences for construction at APS sector 11-BM. The beamline proposal and subsequent funding arise from the
department's general call for new instrumentation at x-ray and
neutron facilities. This state-of-the-art, dedicated powder
instrument will be a part of APS facility beamlines that provide
a majority of beam time (80%) for general users.

Cover of May 2003 issue of Mechanical EngineeringAPS Research Fuels Engineering Interest (Jun. 5)
Award-winning research on the characteristics of fuel sprays from injectors is one of the featured articles in the May 2003 issue of Mechanical Engineering and on the Web site of that magazine. The studies, carried out at APS's X-ray Operation and Research beamline 1-BM and the Cornell High Energy Synchrotron Source, revealed startling new information about fuel sprays, including the presence of a shockwave as the spray leaves the injector nozzle.

The X-ray pulse length emitted by synchrotron sources such as the APS is determined by the electron bunch pulse length, which in turn is limited to about 100ps by essential, long-term stability requirements on the electron beam. However, many interesting structural processes in hard and soft condensed matter and in biological systems occur on time scales shorter than 100 ps...
