  • Simulation of flame and explosion propagation

Explosion research aimed at safer building designs

Researcher Thierry Poinsot, from the European Centre for Research and Advanced Training in Scientific Computation (CERFACS), is leading an international effort to better understand the mechanics of flame and explosion propagation, from the early laminar flame phase to the more aggressive turbulent flame that can incite explosion. Computer resources from the Argonne Leadership Computing Facility (ALCF) are assisting researchers in the development of high fidelity tools to simulate realistic explosion scenarios.

Q&A with Ying Li, ALCF's first Margaret Butler Fellow

The Argonne Leadership Computing Facility (ALCF) has named University of Southern California (USC) doctoral student Ying Li as its first Margaret Butler Fellow. Li will join the ALCF this fall to conduct simulations aimed at advancing batteries and fuel cells using Mira, the ALCF’s IBM Blue Gene/Q supercomputer.

The Margaret Butler Fellowship in Computational Science honors the lifetime achievements of Margaret Butler, a pioneering researcher in both computer science and nuclear energy. Butler served as the director of Argonne’s National Energy Software Center and was the first female Fellow of the American Nuclear Society.

INCITE Seeking Proposals to Advance Science and Engineering at U.S. Leadership Computing Facilities

The Innovative and Novel Computational Impact on Theory and Experiment (INCITE) program is now accepting proposals for high-impact, computationally intensive research campaigns in a broad array of science, engineering, and computer science domains.

From April 16 to June 27, INCITE’s open call provides an opportunity for researchers to make transformational advances in science and technology through large allocations of computer time and supporting resources at the Argonne and Oak Ridge Leadership Computing Facility (LCF) centers, operated by the US Department of Energy (DOE) Office of Science.

  • High school girls viewing a scientific visualization

Conference Introduces High School Students to Supercomputers

On April 10, nearly 400 high school girls from the Chicago area visited Argonne National Laboratory for the 27th annual Science Careers in Search of Women conference.

The conference is designed to give young women the opportunity to “test drive” a science career by attending meetings, networking, and participating in one-on-one conversations with women researchers in the physical, engineering, and life sciences. Students are able to tailor their own experiences during the registration process by choosing the types of science they’d like to explore.

Plasma Turbulence Simulations Reveal Promising Insight for Fusion Energy

With the potential to provide clean, safe, and abundant energy, nuclear fusion has been called the “holy grail” of energy production. But harnessing energy from fusion, the process that powers the sun, has proven to be an extremely difficult challenge.

Scientists have been working to accomplish efficient, self-sustaining fusion reactions for decades, and significant research and development efforts continue in several countries today.

For one such effort, researchers from the Princeton Plasma Physics Laboratory (PPPL), a DOE collaborative national center for fusion and plasma research in New Jersey, are running large-scale simulations at the Argonne Leadership Computing Facility (ALCF) to shed light on the complex physics of fusion energy. Their most recent simulations on Mira, the ALCF’s 10-petaflops Blue Gene/Q supercomputer, revealed that turbulent losses in the plasma are not as large as previously estimated.

Carbon-12 Simulations Help Enhance Particle Physics Experiments

Using ALCF supercomputers to study the carbon-12 nucleus at an unprecedented level of detail, researchers are uncovering results that will help improve the understanding of subatomic particles.

With an Early Science Program (ESP) project at the Argonne Leadership Computing Facility (ALCF), researchers from Argonne, Los Alamos, and Jefferson national laboratories used Mira, the ALCF’s 10-petaflops IBM Blue Gene/Q supercomputer, to make reliable fundamental calculations of neutrino and electron reactions with carbon-12 nuclei.

Led by Argonne senior physicist Steven Pieper, the research team performed the most detailed simulations of the structure of the carbon nucleus to date, with their calculations of carbon-12’s charge form factor and sum rules of the electromagnetic response function.

  • Argonne's Introduce a Girl to Engineering Day

ALCF Staff Help Introduce Girls to Science and Engineering

On Feb. 20, Argonne National Laboratory hosted its 14th annual Introduce a Girl to Engineering Day to give eighth-grade girls an opportunity to learn about science, technology, engineering, and mathematics (STEM) careers.

Several ALCF staff members volunteered to assist with the event, including Emily Shemon and Lisa Childers, who served as mentors.

  • Corrosion

The Core of Corrosion

Anyone who has ever owned a car in a snowy town – or a boat in a salty sea – can tell you just how expensive corrosion can be. One of the world’s most common and costly chemical reactions, corrosion happens frequently at the boundaries between water and metal surfaces. In the past, the process of corrosion has mostly been studied from the metal side of the equation.

However, in a new study, scientists at the Center for Nanoscale Materials at the U.S. Department of Energy’s Argonne National Laboratory investigated the problem from the other side, looking at the dynamics of water containing dissolved ions located in the regions near a metal surface.
