Chaotic 'spin vortices' could lead to new computer memories

Scientists at Argonne have used alternating magnetic fields to control the behavior of “spin vortices” trapped in small dots made from iron and nickel that can be magnetized in two separate ways.

The complicated evolution of an air film during drop impact. (a) Schematic description of air film evolution; namely, when an air film is entrapped during drop impact on a solid surface, it should evolve into a bubble to minimize its surface energy. (b) Schematic of ultrafast x-ray phase-contrast imaging, which enables the tracking of dynamic changes of air- liquid interfaces in real time. To view a larger version of the image, click on it.
Bubble study could improve industrial splash control

For the first time, scientists witnessed the details of the full, ultrafast process of liquid droplets evolving into a bubble when they strike a surface. Their research determined that surface wetness affects the bubble's fate.

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.

October 23, 2012
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.
