Discovery could dramatically boost efficiency of perovskite solar cells

DOE/Lawrence Berkeley National Laboratory
Peer-Reviewed Publication

Scientists from the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have discovered a possible secret to dramatically boosting the efficiency of perovskite solar cells hidden in the nanoscale peaks and valleys of the crystalline material.

Greene scholars explore science and engineering at SLAC

DOE/SLAC National Accelerator Laboratory

Jaden Morgan, a 13-year-old rising freshman who will attend Bellarmine College Preparatory in San Jose this fall, had heard about SLAC's legendary 2-mile-long accelerator but had never been to the lab. This summer he had the chance to see the Department of Energy's SLAC National Accelerator Laboratory facilities up close and hear how they are used to explore the world at the level of atoms and molecules.

See and sort: Developing novel techniques to visualize uncultured microbial cell activity

DOE/Joint Genome Institute
Peer-Reviewed Publication

In a study published online the week of June 27, 2016 in the Proceedings of the National Academy of Sciences (PNAS), Caltech and DOE Joint Genome Institute researchers utilized a recently refined technique to identify both individual active cells, and single clusters of active bacteria and archaea within microbial communities. The DOE is interested in learning how the planet's 'microbial dark matter' can be harnessed for energy and environmental challenges.

Learning about the future from the distant past

DOE/SLAC National Accelerator Laboratory

Our universe came to life nearly 14 billion years ago in the Big Bang -- a tremendously energetic fireball from which the cosmos has been expanding ever since. Today, space is filled with hundreds of billions of galaxies, including our solar system's own galactic home, the Milky Way. But how exactly did the infant universe develop into its current state, and what does it tell us about our future?

NERSC readying for Cori Phase 2 Knights Landing-based system

DOE/Lawrence Berkeley National Laboratory
Peer-Reviewed Publication

For the past year, staff at the Department of Energy's National Energy Research Scientific Computing Center (NERSC) have been preparing users of 20 leading science applications for the arrival of the second phase of its newest supercomputer, Cori, which consists of more than 9,300 nodes containing Intel's Xeon Phi Knights Landing processor -- which was officially unveiled June 20 at the International Supercomputer Conference in Germany. The first compute cabinets are scheduled to arrive in July.

Keeping alive the art of experimental design

DOE/Lawrence Livermore National Laboratory
Grant and Award Announcement

A team of Lawrence Livermore National Laboratory (LLNL) researchers was honored with the Neill Griffiths Award this month, recognizing the most significant contribution to shaped charge technology. The award was presented at the annual International Symposium on Ballistics. The research helped solve a challenge Shell International Exploration and Production faced: how to sever the connection between an offshore drilling rig with the seabed in case of an emergency.

With spiraling light, SLAC X-ray laser offers new glimpses of molecules

DOE/SLAC National Accelerator Laboratory

A new device at the Department of Energy's SLAC National Accelerator Laboratory allows researchers to explore the properties and dynamics of molecules with circularly polarized, or spiraling, light.

On the path toward bionic enzymes

DOE/Lawrence Berkeley National Laboratory
Peer-Reviewed Publication

Berkeley Lab chemists have successfully married chemistry and biology to create reactions never before possible. They did this by replacing the iron normally found in the muscle protein myoglobin with iridium, a noble metal not known to be used by living systems.

New 3-D printed polymer can convert methane to methanol

DOE/Lawrence Livermore National Laboratory
Peer-Reviewed Publication

Lawrence Livermore National Laboratory scientists have combined biology and 3-D printing to create the first reactor that can continuously produce methanol from methane at room temperature and pressure.

X-ray experiments show Hewlett Packard team how memristors work

DOE/SLAC National Accelerator Laboratory

In experiments at two Department of Energy national labs -- SLAC National Accelerator Laboratory and Lawrence Berkeley National Laboratory -- scientists at Hewlett Packard Enterprise (HPE) have experimentally confirmed critical aspects of how a new type of microelectronic device, the memristor, works at an atomic scale.
