Scientists encouraged by Frustraum experiments at NIF

Aug. 7, 2020- 
Initial NIF experiments using a full-scale version of the Frustraum hohlraum have produced nearly round inertial confinement fusion (ICF) implosions and more laser-induced energy absorption by the fuel-filled capsule. National Ignition Facility (NIF) researchers are optimistic that results from the initial tests of the novel angular-shaped hohlraum could create more promising paths forward...

Using the power of the National Ignition Facility (NIF), the world’s highest-energy laser system, researchers at Lawrence Livermore National Laboratory (LLNL) and an international team of collaborators have developed an experimental capability for measuring the basic properties of matter, such as the equation of state (EOS), at the highest pressures thus far achieved in a controlled...

Compressive shearing may start life on other planets

Aug. 4, 2020- 
Massive compressive shearing forces generated by the tidal pull of Jupiter-like planets on their rocky ice-covered moons may form a natural reactor that drives simple amino acids to polymerize into larger compounds. These extreme mechanical forces strongly enhance molecule condensation reactions, opening a new arena of possibilities for the chemical origins of life on Earth and other rocky...

Doctoral fellow improves codes used to simulate interactions between particles moving at high velocities

Aug. 3, 2020- 
Doctoral student Marco Echeverria is spending his second summer conducting research for Lawrence Livermore National Laboratory (LLNL), but this year his summer experience is taking place at a distance from his home in Connecticut.

LLNL researchers achieve greater understanding of color origins in low-power electronic displays

July 31, 2020- 
Today’s low-power, electronic ink displays such as e-book readers produce text through a process called electrophoretic deposition (EPD). Each pixel of the display contains charged black and white particles suspended in a liquid solvent. These particles are moved by electrodes embedded in the devices, causing particles to stick to the electrodes to form words or images. The displays change...

When an Atlas V-541 rocket lifted off Thursday morning (July 30) for Mars from Cape Canaveral Air Force Station with the Perseverance rover in tow, two Lawrence Livermore National Laboratory (LLNL) scientists had front row seats. The pair, Steve Homann and Jessica Osuna, researchers in the Lab’s National Atmospheric Release Advisory Center (NARAC), part of the Nuclear Emergency...

3D nanometer-thin membrane borrows from biology

July 30, 2020- 
Mimicking the structure of the kidney, a team of scientists from Lawrence Livermore National Laboratory (LLNL) and the University of Illinois at Chicago (UIC) have created a three-dimensional nanometer (nm)-thin membrane that breaks the permeance-selectivity trade-off of artificial membranes. Highly permeable and selective membranes are useful for a wide range of applications, such as...

Machine learning model may perfect 3D nanoprinting

July 29, 2020- 
Two-photon lithography (TPL) — a widely used 3D nanoprinting technique that uses laser light to create 3D objects — has shown promise in research applications but has yet to achieve widespread industry acceptance due to limitations on large-scale part production and time-intensive setup. Capable of printing nanoscale features at a very high resolution, TPL uses a laser beam to build...

Carbon emissions, energy flow charts for all U.S. states

July 28, 2020- 
Lawrence Livermore National Laboratory (LLNL) has updated its energy flow charts to include state-by-state energy use for 2015-2018. It also has released carbon emissions charts that depict a breakdown of all 50 states’ carbon emissions from 2014-2017. See the charts. Each year, LLNL releases flow charts that illustrate the nation's consumption and use of energy. This recent release...

LLNS operates the Laboratory for the Department of Energy/National Nuclear Security Administration (DOE/NNSA). As agreed to by the LLNS partners, UC is responsible...

Diving into the structure of molten salts in tight spaces

July 23, 2020- 
Room temperature ionic liquids (ILs), a special class of molten salts, promise far greater electrochemical performance compared to conventional aqueous solutions due to a suite of novel and tunable properties. Over the past two decades, ILs have been explored as a means of improving a range of different technologies, from energy storage and conversion to catalysis to electroplating of metals...

New analysis narrows range in climate sensitivity

July 22, 2020- 
The most advanced and comprehensive analysis of climate sensitivity undertaken has revealed with more confidence than ever how sensitive the Earth’s climate is to carbon dioxide. Climate warming depends on the changing composition of the atmosphere, and the “climate sensitivity” represents the dominant indicator of change, defined as the increase of global air temperature resulting...
