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.

Mysteries of space dust revealed

The first analysis of space dust collected by a special collector onboard NASA’s Stardust mission and sent back to Earth for study in 2006 suggests the tiny specks open a door to studying the origins of the solar system and possibly the origin of life itself. This is the first time synchrotron light sources have been used to look at microscopic particles caught in the path of a comet.

The NMDA receptor is a massive, multi-subunit complex. CSHL researchers found that it looks much like a hot air balloon. The upper, balloon-like portion of the structure is found outside the cell and responds to chemical messengers. Those messengers act like a key to unlock the lower portion of the receptor. This lower portion, corresponding to the basket of the hot air balloon, is embedded in the neuron’s membrane. It creates a narrow channel that allows ions, or electrically charged atoms, to flow into the cell. These many subunit interactions are potential targets for drug discovery. Click to enlarge.
Unprecedented detail of intact neuronal receptor offers blueprint for drug developers

Scientists succeeded in obtaining an unprecedented view of a type of brain-cell receptor that is implicated in a range of neurological illnesses, including Alzheimer’s disease, Parkinson’s disease, depression, schizophrenia, autism, and ischemic injuries associated with stroke.

We live atop the thinnest layer of the Earth: the crust. Below is the mantle (red), outer core (orange), and finally inner core (yellow-white). The lower portion of the mantle is the largest layer – stretching from 400 to 1,800 miles below the surface. Research at Argonne’s Advanced Photon Source recently suggested the makeup of the lower mantle is significantly different from what was previously thought. Image by Johan Swanepoel/Shutterstock.

Composition of Earth’s mantle revisited thanks to research at Argonne’s Advanced Photon Source

Research published last week in Science suggested that the makeup of the Earth’s lower mantle, which makes up the largest part of the Earth by volume, is significantly different than previously thought.

Neutrons and X-rays reveal structure of high-temperature liquid metal oxides

By levitating a bead of ceramic oxide, heating it with a 400-watt carbon dioxide laser, then shooting the molten material with X-rays and neutrons, scientists with the Department of Energy’s Oak Ridge and Argonne national laboratories have revealed unprecedented detail of the structure of high-temperature liquid oxides.
