Understanding the complex turbulent mixing noise sources for jet exhaust nozzles is critical to delivering the next generation of “green” low-noise jet engines. A scalable, compressible Computational Aeroacoustics solver based on Large Eddy Simulation is used to study free-shear layer noise from jet exhaust nozzles.

High-pressure science gets super-sized

The study of materials at extreme conditions took a giant leap forward with the discovery of a way to generate super high pressures without using shock waves whose accompanying heat turns solids to liquid.

Accelerator scientist John Noonan led the development of a superconducting cage-like radio-frequency cavity and a dual electron linear accelerator in an energy-recovery configuration that has the potential to revitalize domestic production of technetium-99m, potentially create thousands of new jobs and save more lives by having this isotope readily available.
Scientists develop affordable way to generate medical isotopes

Scientists at Argonne National Laboratory have developed a safe and affordable way to ensure a reliable U.S. supply of certain medical isotopes. Although the invention is at a conceptual stage, it has the potential to provide critical medical diagnostic material for small regional hospitals.

This is an image of a G-protein-coupled receptor signaling complex whose structure was identified in 2011.  The receptor is in magenta while the different G protein subunits are colored green, red and blue.  Stanford biochemist Brian Kobilka shared the 2012 Nobel Prize in Chemistry for his work in determining the structure of this activated GPCR using X-rays provided by Argonne’s Advanced Photon Source.
Advanced Photon Source lights the way to 2012 Chemistry Nobel

Thanks in part to research performed at Argonne National Laboratory, the 2012 Nobel Prize in Chemistry was awarded today to Americans Brian Kobilka and Robert Lefkowitz for their work on G protein-coupled receptors.

One of the Department of Energy's mobile climate testing facilities has launched aboard the cargo container ship Horizon Spirit as it traverses the Pacific Ocean. During a test run in February 2012, scientists launched a type of sensor called a radiosonde from different locations on the ship to determine the best location to accomplish the launch.

Dark energy camera to probe universe’s biggest mysteries

Eight billion years ago, rays of light from distant galaxies began their long journey to Earth. On Sept. 12, that ancient starlight found its way to a mountaintop in Chile, where the newly-constructed Dark Energy Camera, the most powerful sky-mapping machine ever created, captured and recorded it for the first time.

The reduction of iron(III) oxide minerals is an important component of iron cycling in the subsurface. For example, certain bacteria couple carbon oxidation and iron reduction to obtain energy from growth. Although iron oxides are poor conductors of electricity, electrons that are transfered to an iron oxide mineral are quite mobile, using thermal energy to hop from one iron atom to another. New research used time-resolved X-ray absorption spectroscopy to quantify the hopping rates for different iron(III) mineral phases and to confirm a theoretical picture of how the electron at one site alters the positions of the atoms around it.  This work contributes to our understanding of how soil mineralogy evolves when geochemical or biochemical processes create reducing conditions.
