Making a Movie of Nanocrystals' Structural Evolution

Combined ultrafast snapshots suggest that the crystal symmetry of copper sulfide nanocrystals changes due to interactions between electrons and atoms vibrating in the crystal lattice—an understanding of which could help scientists optimize the functionality of superconductors, magnetic materials, and other strongly correlated systems.

ALCF Selects New Data Science Projects

The Argonne Leadership Computing Facility (ALCF), a U.S. Department of Energy (DOE) Office of Science User Facility, has selected four new projects to continue its ALCF Data Science Program (ADSP). These projects will utilize machine learning, deep learning, and other artificial intelligence (AI) methods to enable data-driven discoveries across scientific disciplines.

Preparing for a Sequence Data Deluge

Accepted 2019 JGI Community Science Program proposals requested terabases of sequence data. Over the summer, the U.S. Department of Energy (DOE) Joint Genome Institute (JGI), a DOE Office of Science User Facility, set an “institutional best” record by sequencing 20.4 trillion bases (Terabases or Tb) in a single month in Walnut Creek, California.

"Choosy" Electronic Correlations Dominate Metallic State of Iron Superconductor

Two families of high-temperature superconductors (HTS)—materials that can conduct electricity without energy loss at unusually high (but still quite cold) temperatures—may be more closely related than scientists originally thought.

Quantum Leap

As part of the DOE Office of Science Quantum Information Science-Enabled Discovery (QuantISED) program, a consortium of three institutions under the leadership of Fermilab scientist Alexander Romanenko has been awarded $3.9 million over two years to further SRF technology for quantum science, potentially boosting the processing speed and storage capacity of quantum devices, including quantum computers and sensors.

Coming Soon to Exascale Computing: Software for Chemistry of Catalysis

The U.S. Department of Energy’s Ames Laboratory is launching a four-year, $3.2 million project to develop software that will bring the power of exascale computers to the computational study and design of catalytic materials.

The Promise of Deep Grooves

A manufacturing technique that could help the semiconductor industry make more powerful computer chips began in the humblest of places — at a lunch table at the U.S. Department of Energy’s (DOE) Argonne National Laboratory.

Modern Modulators for Fermilab Accelerators

New, flexible power modulators give Fermilab’s linear accelerator operators more precise control over particle beams.

Superstars' Secrets

Supercomputing power and algorithms are helping astrophysicists untangle giant stars’ brightness, temperature and chemical variations.

Single Atoms Break Carbon's Strongest Bond

An international team of scientists including researchers at Yale University and the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory have developed a new catalyst for breaking carbon-fluorine bonds, one of the strongest chemical bonds known.
