New classes of magnetoelectric materials promise advances in computing technology

Thanks to new research by an international team of researchers led by Argonne, physicists have developed new methods for controlling magnetic order in a particular class of materials known as “magnetoelectrics.”

High-energy X-rays shine light on mystery of Picasso’s paints

The Art Institute of Chicago teamed up with Argonne National Laboratory to unravel a decades-long debate among art scholars about what kind of paint Picasso used to create his masterpieces.

Gregory Voth's current research focuses on the multiscale theory and simulation of biomolecular and material phenomena, including protein assembly, membrane-protein interactions, charge transport, complex liquids and nanoparticle self-assembly.
Argonne's Voth receives award from American Chemical Society

Argonne National Laboratory and University of Chicago theoretical chemist Gregory Voth has received the 2013 Award in Theoretical Chemistry from the Physical Chemistry Division of the American Chemical Society.

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.

A team led by Argonne National Laboratory used the recently developed Hardware/Hybrid Accelerated Cosmology Codes (HACC) framework to achieve nearly 14 petaflops on the 20-petaflop Sequoia, an IBM BlueGene/Q supercomputer, in a record-setting benchmark run with 3.6 trillion simulation particles.
DOE researchers advance scientific computing with record-setting simulations

Breaking new ground for scientific computing, two teams of Department of Energy scientists have exceeded a sustained performance level of 10 petaflops on the Sequoia supercomputer at the National Nuclear Security Administration’s Lawrence Livermore National Laboratory.

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.
