  • Direct numerical simulation of turbulent flow in nuclear reactor

The science of bubbles

Igor Bolotnov, a professor of nuclear engineering at North Carolina State University, is using Mira to better understand boiling phenomena, bubble formation, and two-phase bubbly flow inside of nuclear reactors, which rely on water/steam conversion to produce energy.

  • The ALCF's Simulation, Data, and Learning Workshop

ALCF workshop supports simulation, data, and learning research

From February 27 to March 1, 2018, the ALCF welcomed more than 50 prospective and current users to the facility for its Simulation, Data, and Learning Workshop. This training event provided an opportunity for attendees to work directly with ALCF staff members and invited experts from Intel, Cray, and Arm, to learn about the systems, tools, frameworks, and techniques that can help advance research in these three areas of scientific computing.

  • Researchers sew atomic lattices seamlessly together

Researchers sew atomic lattices seamlessly together

Researchers from the University of Chicago and Cornell University developed a new technique to “sew” crystals together to join different materials at the atomic level. As part of this study, the team used Argonne’s Mira supercomputer to model a system of nearly 150,000 atoms to explore ripple formation in the materials. This research was published in Science.

  • Schematic of the new Li-air cell design

Out of thin air

Argonne researchers conducted basic science computational studies as part of a collaboration with researchers at the University of Illinois at Chicago to design a “beyond-lithium-ion” battery cell that operates by running on air over many charge and discharge cycles. The design offers energy storage capacity about three times that of a lithium-ion battery, with significant potential for further improvements.

  • Membrane bound structure of the Sarcoplasmic reticulum calcium pump

Theta provides insights into the building blocks of life

As part of the ALCF's Theta Early Science Program, researchers from the University of Chicago used the new supercomputer to advance the study of membrane transport proteins. Their work included an investigation of how pH conditions affect the passage of small drug molecules across cell membranes, lending insight into the origin of acidity/alkalinity effects on drug adsorption.

  • Colleen Bertoni

Q&A with Colleen Bertoni, the ALCF’s Margaret Butler Fellow

Now entering the second year of the two-year fellowship, Bertoni is working to improve the performance and accuracy of a new quantum chemistry code that can be used to calculate the properties of complex chemical systems, such as excitons for solar cells. Using this new code, she aims to carry out large-scale computational studies on ALCF supercomputers, with the goal of providing insights into chemical systems that could ultimately help scientists to design better materials.

Argonne scientists uncover fresh insights about the structure of salt water

New insight into science that seems, on its surface, exceedingly simple — what happens when you add salt to water — could ultimately lead to a better understanding of biochemical processes in cells and perhaps advance sources of clean energy.
