Argonne scientists and collaborators used high energy X-rays from the Advanced Photon Source to create detailed images of nanoscale materials. The scientists are working to develop a dedicated facility for the process at Argonne.
Lensless camera uses X-rays to view nanoscale materials and biological specimens

X-rays have been used for decades to take pictures of broken bones, but scientists at Argonne and their collaborators have developed a lensless X-ray technique that can take images of ultra-small structures buried in nanoparticles and nanomaterials, and features within whole biological cells such as cellular nuclei.

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.

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.

Kathleen Carrado Gregar has been elected to the 2012 class of Fellows of the American Chemical Society.
Carrado Gregar inducted into American Chemical Society

Kathleen Carrado Gregar, the User and Outreach Programs Manager at the Center for Nanoscale Materials at Argonne, has been elected to the 2012 class of Fellows of the American Chemical Society.

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.

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.

High-energy X-rays shine light on mystery of Picasso’s paints

The Art Institute of Chicago teamed up with Argonne National Laboratory to unravel a decades-long debate among art scholars about what kind of paint Picasso used to create his masterpieces.
