Fast heat flows in warm dense aluminum

Aug. 31, 2017 - Thermal conductivity is one of the most crucial physical properties of matter when it comes to understanding heat transport, hydrodynamic evolution and energy balance in systems ranging from astrophysical objects to fusion plasmas. In the warm dense matter (WDM) regime, experimental data are very...

Reducing reflectivity in solar cells and optics with micro- and...

Aug. 30, 2017 - When it comes to solar cells, less is more -- the less their surfaces reflect a sun’s rays, the more energy can be generated. A typical fix to the problem of reflectivity is an anti-reflective coating, but that might not always be the best solution, depending on the application. Lawrence Livermore...

Plutonium research to advance stockpile safely

Aug. 29, 2017 - Conducting an experiment that combines high explosives with plutonium -- a special nuclear material used in nuclear weapons -- is no trivial matter. Not only do researchers need to ensure the plutonium remains “subcritical” to avoid a nuclear explosion, they must be absolutely certain that these...

Perfecting the spider’s art to support NIF targets

Aug. 28, 2017 - Materials scientist Xavier Lepró can’t grow his “spider webs” fast enough to swing from skyscrapers like Spiderman, but he can best another web-maker, Mother Nature, when it comes to consistency. Lepró helped pioneer the spinning of spider-silk-like yarns for use in suspending target capsules...

Carbon nanotubes worth their salt

Aug. 24, 2017 - Lawrence Livermore (LLNL) scientists, in collaboration with researchers at Northeastern University, have developed carbon nanotube pores that can exclude salt from seawater. The team also found that water permeability in carbon nanotubes (CNTs) with diameters smaller than a nanometer (0.8 nm)...

Using real-world data, Lab scientists answer key questions about...

Aug. 23, 2017 - In the event of an accidental radiological release from a nuclear power plant reactor or industrial facility, tracing the aerial plume of radiation to its source in a timely manner could be a crucial factor for emergency responders, risk assessors and investigators. Utilizing data collected during...

Scientists create ‘diamond rain’ that forms in the interior of...

Aug. 22, 2017 - In an experiment designed to mimic the conditions deep inside the icy giant planets of our solar system, scientists observed “diamond rain” for the first time as it formed in high-pressure conditions. Extremely high pressure squeezes hydrogen and carbon found in the interior of these planets to...

NIF’s night Owls: Where the wild things are

Aug. 18, 2017 - From sunset to sunrise, while others slumber, the "Owls" of the National Ignition Facility nurture the world’s most energetic laser through some of its most productive hours. On this particular summer night, Shot Director Steve Weaver is the Owl Shift leader of 16 scientists, engineers and...

Lab scientist takes a leap in the dark

Aug. 17, 2017 - He could have been a professional trombone player in a jazz ensemble or a chef specializing in New Mexican cuisine.   However, Michael Schneider took a very different path. He became an explorer looking for the meaning of the universe in the form of dark energy.   With the help of the Large...

Shock front probed by protons

Aug. 10, 2017 - A shock front is usually considered as a simple discontinuity in density or pressure. Yet in strongly shocked gases, the atoms are ionized into electrons and ions. The large difference in the electron pressure across the shock front can generate a strong electric field. In experimental campaigns...
