Argonne Impacts State by State

Argonne’s collaborations in Mississippi and across the United States have led to groundbreaking discoveries and development of new technologies that help meet the nation’s needs for sustainable energy, economic prosperity, and security.

Scientists at the U.S. Department of Energy’s (DOE) Argonne National Laboratory and Mississippi State University are collaborating in a multiyear effort to improve the nation’s electric power grid. The three-year, DOE-funded project, titled Macro-Resiliency of the North American Power Grid,” links scientists at the state’s flagship research university with researchers in Argonne’s Mathematics and Computer Science division, who create cutting-edge algorithms and software in numerical optimization and high-performance computing. The project’s objective is to develop a computationally efficient model that can capture electromechanical wave propagations within wide-area electric power systems. Researchers believe such a model will help them investigate strategies that will prevent cascading system failures (a common occurrence during periods of high energy use) in the presence of large, unexpected disturbances. The model also would allow users to identify system weak points and create strategies to avoid power blackouts.

Argonne scientists collaborated with nuclear physicist Lamiaa El Fassi of Mississippi State University in her research investigating the subatomic structure of nuclei. El Fassi studied highly energetic neutrons and protons, which are known to pair together inside the nucleus for very short amounts of time.

El Fassi’s research confirmed that even in neutron-rich nuclei, minority protons, on average, are more active ― and faster ― than majority neutrons. The team’s findings facilitate a better understanding of how atomic nuclei hold together. The discovery may also give scientists insights about neutron stars, the objects formed by the collapsed core of a giant star that has imploded — for example, how neutron stars form and how even a tiny amount of protons could affect their behavior.

Conducted at the DOE’s Thomas Jefferson National Accelerator Facility (Newport News, Virginia), the study involved more than 180 scientists from 45 institutions worldwide.
