A New Multilayer-Based Grating for Hard X-ray Grating Interferometry

November 20, 2013

A new kind of x-ray multilayer grating that could open a pathway for high-sensitivity, hard x-ray phase contrast full-field imaging of large samples has been developed at the National Institutes of Health and at Argonne National Laboratory. In tests the device produced phase-contrast images of vascular structures in a mouse kidney specimen that rival those obtained with magnetic resonance imaging and that were previously invisible with conventional attenuation-based x-ray imaging methods

Breaking Records in Neurological Microradiology

August 9, 2012

New techniques for imaging with unprecedented detail and resolution the complex, tree-like branching nature of neuronal networks have been developed by researchers utilizing by the U.S. Department of Energy Office of Science’s Advanced Photon Source, opening the door to three-dimensional tomographic reconstructions, a vital tool for studying the brain and nervous system.

Visualizing the Flow of Molten Rock through Seabed Mantle

July 27, 2011

New information about how most of the Earth's crust formed has been uncovered by investigators who utilized the U.S. Department of Energy Office of Science's Advanced Photon Source at Argonne to obtain unprecedented, three-dimensional x-ray images of melted rock. Their results offer a more sophisticated picture of rock porosity and a resolution of the discrepancy between permeability and melt velocity.

How Did the Caterpillar Cross the Road?

July 2010

Researchers have discovered that at least one species of caterpillar precedes each step with a thrust of its gut. The finding, based on experiments carried out at the U.S. Department of Energy's Advanced Photon Source at Argonne National Laboratory points to an entirely new mode of animal locomotion and could lead researchers to develop new robotic tools for exploration and medicine.

Pumping Through the Middle Crust

July 29, 2009

A team of geologists and geophysicists using the U.S. Department of Energy's Advanced Photon Source has shed light on a fluid transfer in the middle continental crust, a phenomenon that was formerly poorly understood. Their work could lead to a fuller understanding of fluid migration through rock, with possible wide application in deciphering important geological processes including earthquakes.

Extreme Pressure Reveals a Volume Expansion Phenomenon

September 26, 2008

The behavior of materials under extreme conditions of pressure, temperature, and magnetic fields is an important area of investigation in the materials sciences and a key to developing new materials with superior qualities. Researchers using an x-ray beamline at the Advanced Photon Source (APS) at the U.S. Department of Energy's Argonne National Laboratory employed a new technique developed at another APS beamline to examine amorphous (non-crystalline) selenium (a-Se) under great pressure. Their results answer a long-standing question about the electrical properties a-Se exhibits when subjected to extreme pressure, and show that the new x-ray technique holds great promise for gaining insights about the properties of materials under those conditions.
