DOE Office of Science honors two early career Lab scientists

Two scientists from Lawrence Livermore National Laboratory (LLNL) are recipients of the Department of Energy’s (DOE) Office of Science Early Career Research Program award. Federica Coppari and Erin Nuccio are among 76 scientists nationwide selected for the recognition. Under the program, typical awards for DOE national laboratory staff are $500,000 per year for five years.

Making Quantum ‘Waves’ in Ultrathin Materials

A team of researchers co-led by Berkeley Lab has observed unusually long-lived wavelike electrons called “plasmons” in a new class of electronically conducting material. Plasmons are very important for determining the optical and electronic properties of metals.

Closely spaced hydrogen atoms could facilitate superconductivity in ambient conditions

An international team of researchers has discovered the hydrogen atoms in a metal hydride material are much more tightly spaced than had been predicted for decades—a feature that could possibly facilitate superconductivity at or near room temperature and pressure. The scientists conducted neutron scattering experiments at the Department of Energy’s Oak Ridge National Laboratory on samples of zirconium vanadium hydride.

DIII-D Researchers Use Machine Learning to Steer Fusion Plasmas Near Operational Limits

Researchers at the DIII-D National Fusion Facility recently achieved a scientific first when they used machine learning calculations to automatically prevent fusion plasma disruptions in real time, while simultaneously optimizing the plasma for peak performance. The new experiments are the first of what they expect to be a wave of research in which machine learning–augmented controls could broaden the understanding of fusion plasmas. The work may help deliver reliable, peak-performance operation of future fusion reactors.

New material captures and converts toxic air pollutant into industrial chemical

A team led by the University of Manchester has developed a metal-organic framework material providing a selective, reversible and repeatable capability to capture a toxic air pollutant, nitrogen dioxide, which is produced by combusting fossil fuels. The material then requires only water and air to convert the captured gas into nitric acid for industrial use.
