John Bahns, Subramanian Sankaranarayanan, Liaohai Chen and Stephen Gray find new way to assemble nanoparticles.
Scientists use light to join nanoparticles into new materials

For many years, scientists have searched for ways to assemble nanoparticles—tiny bits of matter less than a millionth of an inch across—into larger structures of any desired shape and form at will. This effect has been achieved in a new study by using a laser as if it were a magic wand, creating an assembled, continuous filament as the laser beam is moved around.

Argonne chemist Seth Darling measures the performance of a nanostructured organic photovoltaic cell.
New, balanced approach calculates lifetime solar energy cost

Researchers at Argonne National Laboratory have developed a new and more instructive approach to calculate the lifetime cost for a solar-generated energy system for comparison to other energy systems.

This image of a Type Ia Supernova, created by Brad Gallagher using data from George Jordan and Donald Q. Lamb (University of Chicago), was based on research funded by INCITE. The blue surface approximates the surface of the star and the yellow surface shows the flame front, behind which there is ash from burning stellar material.
Argonne scientists awarded supercomputing time to enable scientific breakthroughs

Four researchers at Argonne National Laboratory lead projects that have been awarded a total of 65 million hours of computing time on Argonne’s energy-efficient Blue Gene/P (“Intrepid”) supercomputer. The researchers will conduct advanced simulation and analysis, performing virtual experiments that would be almost impossible and impractical in the natural world.

Two Argonne researchers receive Presidential honors

Two materials scientists at Argonne National Laboratory have received the 2009 Presidential Early Career Awards for Scientists and Engineers, the nation’s highest honor for researchers in the beginning stages of their independent research careers.

These silver nanoplates are decorated with silver oxy salt nanoparticles along the edges. These nanostructures were grown under irradiation of high-energy x-rays, which allowed scientists to "watch" them grow in real time. The image is from a scanning electron microscope.
Argonne scientists watch the birth of nanoparticles for the first time

The revolutionary technique allows researchers to learn about the early stages of nanoparticle generation, long a mystery due to inadequate probing methods, and could lead to improved performance of the nanomaterials in applications including solar cells, sensing and more.

New technique allows 3-D visualization of quantum property

Scientists at Argonne National Laboratory have developed a new technique that maps the magnetic vector potential — one of the most important electromagnetic quantities and a foundation of quantum mechanics — in three dimensions.

Argonne scientist Yugang Sun examines silver chloride nanowires. The nanowires, when decorated with gold nanoparticles, can have pollution-controlling properties.
Gold nanoparticles create visible-light catalysis in nanowires

A scientist at the U.S. Department of Energy’s (DOE) Argonne National Laboratory has created visible-light catalysis, using silver chloride nanowires decorated with gold nanoparticles, that may decompose organic molecules in polluted water.

Assistant physicist Zhang Jiang (from left) examines a X-ray diffraction as physicist Jin Wang and nanoscientist Xiao-Min Lin prepare a sample at one of the Advanced Photon Source’s beamlines. The Argonne scientists have examined nanoparticle crystallization in unprecedented detail using the high powered X-rays of the APS.
Argonne scientists reveal secret of nanoparticle crystallization in real time

A collaboration between the Advanced Photon Source and Center for Nanoscale Materials at Argonne National Laboratory has "seen" the crystallization of nanoparticles in unprecedented detail.
