The Advanced Photon Source (APS) at Argonne National Laboratory is a national synchrotron x-ray research facility funded by the U.S. Department of Energy, Office of Science, Office of Basic Energy Sciences. The APS provides the brightest x-ray beams in the Western Hemisphere to more than 5,000 scientists worldwide.

Science & Research Highlights

Excitons are a key element in the functioning of semiconductors and insulators. Understanding their structure and behavior is vitally important to the development of new materials and technologies. Research by experimenters using two beamlines at the U.S. Department of Energy’s Argonne Advanced Photon Source could set the stage for improving materials used for alternative energy sources, while settling a 70-year-old controversy.

Imagine having to copy an entire book by hand without missing a comma. Our cells face a similar task every time they divide. They must duplicate both their DNA and a subtle pattern of punctuation-like modifications on the DNA known as methylation. Scientists using an x-ray beamline at the U.S. Department of Energy’s Argonne Advanced Photon Source caughtt in action one of the tools mammalian cells use to maintain their pattern of methylation.

A potentially important step in the treatment of leukemia has been taken by researchers who used an x-ray beamline at the Argonne Advanced Photon Source to determine the structure of a receptor in the blood control system that, when damaged, is responsible for a variety of diseases, including certain types of leukemia and some inflammatory diseases such as rheumatoid arthritis and asthma. This discovery helps to explain, for the first time, how this receptor is activated and could form a springboard for the development of new treatments.

The lengths of bonds connecting water molecules demonstrate quantum effects and help explain some of water’s weirdness, according to research carried out at the Argonne Advanced Photon Source, combined with neutron data from Rutherford Appleton Laboratory in Didcot, England, and a computer simulation.

Oxygen, the third most abundant element in the cosmos and essential to life on Earth, changes its form dramatically under pressure. Researchers using two x-ray beamlines at the Argonne Advanced Photon Source have gained new insights into the molecular interactions that occur as oxygen undergoes transitions, in particular the origin of a particular (and important) molecular cluster in the red-colored dense solid oxygen.

The search for ways to conserve energy is leading scientists to explore unexpected but important avenues. Argonne researchers using three U.S. Department of Energy facilities have developed a new alloy that could save over $1 billion per year in lost energy for the U.S. hydrogen industry alone.

As Guvenc Akgul goes about learning the finer points of x-ray spectroscopy from his colleagues at the U.S. Department of Energy’s Advanced Photon Source, he represents a bridge between countries that, while separated by culture, distance, or regional factionalism, can find common ground in science at synchrotron x-ray research facilities.
