November 25, 2013Certain unusual properties of water have intrigued researchers for decades, but are hard to investigate owing to inherently small length scales and complex interactions. Now researchers using the Advanced Photon Source at Argonne have achieved the first experimental observation of the arrangements and mobility of soft nanoparticles in dense suspensions that mirror the anomalies observed in complex liquids like water in a colloidal suspension. This finding extends the toolbox of researchers interested in using suspensions to mimic molecular liquids.

March 14, 2013Discovering how living things absorb and convert light energy into a form that can change the molecules involved in such processes would not only help scientists understand them, but could lead to ways to mimic such processes for more efficient solar energy conversion, for instance. A clearer understanding of how light can drive biological processes has emerged from x-ray diffraction studies carried out on beamlines at the U.S. Department of Energy Office of Science's Advanced Photon Source and the European Synchrotron Radiation Facility, helping shed a brighter light on some of life's most critical processes.
September 24, 2012Technologies such as microelectronics and lithography require nanoscale polymer films that sit on other materials. An understanding of the interplay between the dynamics of thin film and underlying substrate is crucial in determining the appropriate materials to be utilized for new and improved applications. Experiments at the Argonne Advanced Photon Source provide important new insights about thin polymer films on various substrates.

January 6, 2012The development of polymer nanostructures and nanoscale devices for a wide variety of applications could emerge from new information about the interplay between nanoscale interfaces in polymeric materials, thanks to research carried out at the U.S. Department of Energy Office of Science’s Advanced Photon Source at Argonne National Laboratory.
February 17, 2014Experiments at the U.S. Department of Energy Office of Science′s Advanced Photon Source studied the changes occurring in the domain pattern and atomic structure of a superlattice. These insights have the potential to extend the functionalities of complex oxides by providing the means to tune the field and time dependences of a material′s electronic properties, perhaps paving the way for their use in new, multifunctional microelectronic devices.
March 14, 2013For decades, biochemists and biophysicists have worked to reveal the relationship between protein structural complexity and function, only to discover more complexity. They relied on freeze-trapping to capture protein intermediates at various steps along a biochemical pathway. Now a research group has developed the necessary infrastructure at the BioCARS beamline at the Argonne Advanced Photon Source to watch proteins function in real time on the picosecond time scale. Their work brings us many steps closer to knowing how proteins function, or malfunction when leading to disease.
