The reduction of iron(III) oxide minerals is an important component of iron cycling in the subsurface. For example, certain bacteria couple carbon oxidation and iron reduction to obtain energy from growth. Although iron oxides are poor conductors of electricity, electrons that are transfered to an iron oxide mineral are quite mobile, using thermal energy to hop from one iron atom to another. New research used time-resolved X-ray absorption spectroscopy to quantify the hopping rates for different iron(III) mineral phases and to confirm a theoretical picture of how the electron at one site alters the positions of the atoms around it.  This work contributes to our understanding of how soil mineralogy evolves when geochemical or biochemical processes create reducing conditions.

A clearer look at how iron reacts in the environment

Using ultrafast X-rays, scientists for the first time have watched how quickly electrons hop their way through rust nanoparticles.

Tao Sun and Jin Wang, scientists at Argonne National Laboratory, use the Advanced Photon Source to design and test a new technique for X-ray detection that for the first time allows 3-D reconstructions of surface material with high-resolution.
Nano, photonic research gets boost from new 3-D visualization technology

For the first time, X-ray scientists have combined high-resolution imaging with 3-D viewing of the surface layer of material using X-ray vision in a way that does not damage the sample.

Deep canyons can be etched into materials at the nanoscale with a new SIS-based lithography technique by Argonne scientists.
Argonne nanoscientists invent better etching technique

Imagine yourself nano-sized, standing on the edge of a soon-to-be computer chip. Down shoots a beam of electrons, carving precise topography that is then etched the depth of the Grand Canyon into the chip.

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.

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.
