The synchrotron X-ray scanning tunneling microscopy concept allowed Argonne National Laboratory and Ohio University researchers to achieve a recording-breaking resolution of a nanoscale material. They combined of a synchrotron X-ray as a probe and a nanofabricated smart tip as a detector to fingerprint individual nickel clusters on a copper surface at a two-nanometer resolution and at the ultimate single-atomic height sensitivity. And by varying the photon energy, researchers successfully measured photoionization cross sections of a single nickel nanocluster – opening the door to new opportunities for chemical imaging of nanoscale materials.

Powerful new technique simultaneously determines nanomaterials' chemical makeup, topography

A team of researchers from the U.S. Department of Energy's Argonne National Laboratory and Ohio University have devised a powerful technique that simultaneously resolves the chemical characterization and topography of nanoscale materials down to the height of a single atom.

An Argonne-led research team found that when uranium dioxide melts, the number of oxygen atoms around uranium changes from eight-fold to a mixture of six- and sevenfold, which alters how it interacts with other materials. The discovery about will help scientists select the best computational model to use when simulating severe nuclear reactor accidents. (Click image to enlarge)
Discovery sheds light on nuclear reactor fuel behavior during a severe event

A new discovery about the atomic structure of uranium dioxide will help scientists select the best computational model to simulate severe nuclear reactor accidents.

The surface acoustic wave (SAW) sensor detects frequency changes in waves that propagate through its crystalline structure. This makes it ideal for detecting the presence of chemicals or biomarkers present in a liquid or gas. For example, it can detect cancer proteins attached to a receptor on the sensor surface.

Researchers develop new acoustic sensor for chemical and biological detection

A new microscopic acoustic device that has been dramatically improved by scientists at the U.S. Department of Energy’s Argonne National Laboratory has the potential to form a new test for ovarian cancer or the presence of a particular chemical.

Research has shown that protons and neutrons that have briefly paired up in the nucleus have higher-average momentum, which allows a greater fraction of the protons than neutrons to have high momentum in relatively neutron-rich nuclei, such as carbon, aluminum, iron and lead. This result is contrary to long-accepted theories large nuclei and has implications for ultra-cold atomic gas systems and neutron stars.
Protons hog the momentum in neutron-rich nuclei

A team of researchers, including scientists from Jefferson and Argonne national laboratories, found that protons and neutrons that have briefly paired up in the nucleus have higher-average momentum, leaving less for non-paired nucleons - including in nuclei heavier than carbon.

Researchers fight friction and wear with one-atom-thick graphene

Nanoscientist Anirudha Sumant and his colleagues at Argonne’s Center for Nanoscale Materials and Argonne’s Energy Systems division applied a one-atom-thick layer of graphene, a two-dimensional form of carbon, in between a steel ball and a steel disk. They found that just the single layer of graphene lasted for more than 6,500 “wear cycles,” a dramatic improvement over conventional lubricants like graphite or molybdenum disulfide.
