Researchers from Argonne National Laboratory developed a first-principles-based, variable-charge force field that has shown to accurately predict bulk and nanoscale structural and thermodynamic properties of IrO2. Catalytic properties pertaining to the oxygen reduction reaction, which drives water-splitting for the production of hydrogen fuel, were found to depend on the coordination and charge transfer at the IrO2 nanocluster surface.

Researchers from Carnegie Mellon University used the synchrotron X-rays at the Advanced Photon Source to image porosity, or the presence of pores, in a 3-D printed titanium alloy, Ti-6Al-4V. This image shows microtomography reconstructions of Ti-6Al-4V samples printed at different speed functions with an electron beam melting machine. When printed at high-speed functions, which result in smaller melt pools, porosity in Ti-6Al-4V increased. At low-speed functions, which result in larger melt pools, porosity decreased but was still present at the sample surface. (Image courtesy of Ross Cunningham, Carnegie Mellon University)
Intense X-rays expose tiny flaws in 3-D printed titanium that can lead to breakage over time

To understand the cause of porosity in 3-D printed titanium alloys, researchers from Carnegie Mellon University came to Argonne for the intense synchrotron X-rays and a rapid imaging tool known as microtomography at the Advanced Photon Source.

On the left, a schematic shows the experimental setup for measuring spin dynamics in a sample of YIG. On the right, a Brillouin light scattering map of a micro-sized bar of YIG excited via an electrical current through a platinum overlayer reveals a strong spin-wave localization in the center of the sample known as a “bullet.” The color red indicates a high-spin wave intensity and the color blue indicates an absence of spin waves.

Could the future of low-power computing be magnetism?

Researchers at the U.S. Department of Energy's (DOE's) Argonne National Laboratory have made two recent advances in the field of spin-wave logic, or the potential use of magnetic spins to transmit and manipulate data.

The three peptides shown in the shaded box are currently being experimentally validated by the Baker Laboratory. For comparison, the peptides are shown with the small molecule that is the active agent in aspirin and a large protein that is used as an anti-HIV antibody.
Software optimized on Mira advances design of mini-proteins for medicines, materials

Scientists at the University of Washington are using Mira to virtually design unique artificial peptides, or short proteins. As the researchers begin to develop new peptides, they are optimizing their in-house software to test thousands of potential peptide structure designs in tandem, requiring a state-of-the-art supercomputer.

10 highlights celebrating 10 years of Argonne Leadership Computing Facility

The Argonne Leadership Computing Facility turns 10 years old this week. Here are 10 highlights to celebrate its first decade of accomplishments.

(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.
