LED Material Shines Under Strain

A team led by researchers at Lawrence Berkeley National Laboratory (Berkeley Lab) and UC Berkeley has demonstrated an approach for achieving LEDs with near 100% light-emission efficiency at all brightness levels.

One scientist’s trash is another’s treasure:

While making materials samples to pursue their own research goals, scientists at the U.S. Department of Energy’s Ames Laboratory discovered that an unwanted byproduct of their experiments was an extremely high-quality and difficult-to-obtain substance sought after by scientists researching layered materials.

This crystal impurity is sheer perfection

Scientists at Berkeley Lab and UC Berkeley have developed a nanoparticle composite that grows into 3D crystals. The new 3D-grown material could speed up production and eliminate errors in the mass manufacturing of nanoscale photonics for smart buildings or actuators for robotics.

Key to Carbon-Free Cars? Look to the Stars

In a decade-long quest, scientists at Berkeley Lab, the University of Hawaii, and Florida International University uncover new clues to the origins of the universe – and land new chemistry for cleaner combustion engines

Are Heavy Metals Toxic? Scientists Find Surprising New Clues in Yeast

Scientists at Berkeley Lab and UC Berkeley have compiled the most complete library yet of lanthanide heavy metals and their potential toxicity – by exposing baker’s yeast to lanthanides. Their findings could help researchers uncover hidden pathways between lanthanide metals and disease.

General Atomics Completes Fabrication and Testing of First ITER Central Solenoid Module

After nearly five years of fabrication and a battery of rigorous testing and troubleshooting, General Atomics (GA) has completed the first major milestone in one of the United States’ largest contributions to the ITER fusion project in France. The first module of the ITER Central Solenoid will join six others still in fabrication to make up the largest pulsed superconducting magnet in the world. The Central Solenoid will play a critical role in ITER’s mission to establish fusion as a practical, safe and nearly inexhaustible source of clean, abundant and carbon-free electricity.

DIII-D Scientists to Work with PPPL to Find a Path to Sustained Fusion Energy

Researchers from the DIII-D National Fusion Facility are preparing to support their colleagues at the National Spherical Tokamak Experiment-Upgrade (NSTX-U) at the U.S Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) in a quest to develop sustained fusion energy. Under recently announced DOE funding programs, two teams at DIII-D will perform research on physics and instrumentation for NSTX-U as the facility’s staff work to restart operations late next year.

Quantum light squeezes the noise out of microscopy signals

Researchers at Oak Ridge National Laboratory used quantum optics to advance state-of-the-art microscopy and illuminate a path to detecting material properties with greater sensitivity than is possible with traditional tools.

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.

Living on the Edge: How a 2D Material Got Its Shape

A team of scientists led by the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) has gained valuable insight into 3D transition metal oxide nanoparticles’ natural “edge” for 2D growth.
