‘Quantum annealer’ shows promise in study

Aug. 21, 2019 -  
An international team of researchers, including Lawrence Livermore National Laboratory (LLNL) physicist Arjun Gambhir, has developed a new algorithm for solving polynomial systems of equations using a type of quantum computer called a “quantum annealer.” The team systematically examined how this...

Nanowire arrays could improve solar cells

Aug. 8, 2019 -  
Transparent electrodes are a critical component of solar cells and electronic displays. To collect electricity in a solar cell or inject electricity for a display, you need a conductive contact, like a metal, but you also need to be able to let light in (for solar cells) or out (for displays)...

Klein named American Meteorological fellow

July 31, 2019 -  
Atmospheric scientist Stephen Klein has been selected as a fellow of the American Meteorological Society. The American Meteorological Society (AMS) is the premier scientific and professional organization in the United States promoting and disseminating information about the atmospheric, oceanic and...

Study reveals new structure of gold at extremes

July 30, 2019 -  
Gold is an extremely important material for high-pressure experiments and is considered the "gold standard" for calculating pressure in static diamond anvil cell experiments. When compressed slowly at room temperature (on the order of seconds to minutes), gold prefers to be the face-centered cubic...

Under pressure: New device’s 1.6 billion atmospheres per second assists impact studies

July 11, 2019 -  
A new super-fast high-pressure device at DESY's PERA III X-ray light source allows scientists to simulate and study earthquakes and meteorite impacts more realistically in the lab. The new-generation dynamic diamond anvil cell (dDAC), developed by scientists from Lawrence Livermore National...

Co-Optima identifies six new blendstocks for improved fuel economy, vehicle performance

July 3, 2019 -  
Three years after embarking upon a rigorous evaluation of a pool of more than 400 candidates, researchers with the Co-Optimization of Fuels & Engines (Co-Optima) initiative have identified six blendstocks from two chemical families that exhibit the greatest potential to dramatically increase...

Did comet impacts jump-start life on Earth?

June 27, 2019 -  
Comets screaming through the atmosphere of early Earth at tens of thousands of miles per hour likely contained measurable amounts of protein-forming amino acids. Upon impact, these amino acids self-assembled into significantly larger nitrogen-containing aromatic structures that are likely...

Stellar reactions in a galaxy not so far, far away

July 1, 2019 -  
Few people over the course of history have had a hand in discovering an atomic element. Yet nuclear chemist Dawn Shaughnessy joined a team of scientists from Lawrence Livermore National Laboratory ( LLNL ) and Russia that discovered five elements from 1989 to 2010. Now she leads the Nuclear and...

High-powered laser diodes can reduce residual stress in metal 3D printed parts

June 25, 2019 -  
In 3D printing, residual stress can build up in parts during the printing process due to the expansion of heated material and contraction of cold material, generating forces that can distort the part and cause cracks that can weaken or tear a part to pieces, especially in metals. Researchers at...
