(a) X-rays from the APS interact with cerium jets and impact a scintillator that converts the X-rays to visible light, while photonic Doppler velocimetry (PDV) probes simultaneously measure jet-growth velocities. Four intensified charge-coupled device (ICCD) detectors then capture the optically multiplexed images. (b) Multiple images of a jet as it crosses the field-of-view of the ICCD detectors. The groove in the back of the cerium sample is shown on the left. (courtesy of Brian Jensen, Los Alamos National Laboratory)
Jets reveal cerium’s shocked strength

"Jets” formed after shockwaves passed through cerium metal provided the yield stress of cerium in its post-shock state, indicating the stress that would cause it to become permanently deformed.

Researchers at Argonne’s Center for Nanoscale Materials have confirmed the growth of self-directed graphene nanoribbons on the surface of the semiconducting material germanium by researchers at the University of Wisconsin at Madison. (Click on image to enlarge.)
One Direction: Researchers grow nanocircuitry with semiconducting graphene nanoribbons

Researchers from the University of Wisconsin at Madison are the first to grow self-directed graphene nanoribbons on the surface of the semiconducting material germanium. This allows the semiconducting industry to tailor specific paths for nanocircuitry in their technologies. The findings were confirmed at Argonne’s Center for Nanoscale Materials.

‘Greener’ way to assemble materials for solar applications

Polymers used in solar cells today require solvents that can harm the environment, but scientists using the Advanced Photon Source at Argonne have found a “greener” way to control the assembly of photovoltaic polymers in water using a surfactant— a detergent-like molecule—as a template.

Researchers have measured how the atoms within electrically insulating solids reorient due to an applied electric field. Shown here for Na1/2Bi1/2TiO3, bismuth ions (purple) align along the electric field direction relative to their surrounding titanium ions (blue). Oxygen ions not shown. (Click image to enlarge.)

Schematic illustration of an entropy stabilized oxide at the atomic scale. The grey spheres represent the oxygen sub lattice in the rock salt-structured crystal while the colored spheres represent the metal cations. Each different color corresponds to different elemental species. Note that different metals are distributed randomly. Image credit: Jon-Paul Maria. (Click image to enlarge.)
Researchers create first entropy-stabilized complex oxide alloys

Researchers from North Carolina State University, using the Advanced Photon Source, have created the first entropy-stabilized alloy that incorporates oxides – and demonstrated conclusively that the crystalline structure of the material can be determined by disorder at the atomic scale rather than chemical bonding.
