Miniapps Pick Up the Pace

August 29, 2013 1:17 pm | Award Winners

Computers process information quickly, but they perform sequentially. Because clock speeds have stalled, future performance gains come almost solely from running sets of instructions concurrently. This will force fundamental changes for all computer components, making co-design (collaborative, simultaneous development of all system components) essential. Developed by a team led by Sandia National Laboratories, Mantevo Suite 1.0 is a promising approach to co-design.

Almost as sensitive as a dog’s nose

August 29, 2013 9:38 am | by Peter Rüegg, ETH Zurich | News | Comments

Using carbon nanotubes, a research team in Switzerland and California has developed a sensor that greatly amplifies the sensitivity of commonly used but typically weak vibrational spectroscopic methods, such as Raman spectroscopy. This type of sensor makes it possible to detect molecules present in the tiniest of concentrations.

Bringing Power to Fiber Lasers

August 28, 2013 1:11 pm | Award Winners

Fiber lasers and amplifiers are common in a number of national defense applications. Increasing the average power of these lasers is straightforward: Use multiple lasers in multi-mode operation. However, to maintain the ability to focus, single-mode operation is often necessary. Scientists at Lawrence Livermore National Laboratory have developed Efficient Mode-Converters for High-Power Fiber Amplifiers as a way to help developers scale fiber-based laser installations to higher power levels while still retaining effective focus.

DNA Provides Clean Air

August 28, 2013 11:26 am | Award Winners

One of the most overlooked threats to human health is poor indoor air quality. Various air pollutants exist indoors, including biological pollutants, secondhand smoke, combustion pollutants and other chemicals, and can pool in spaces with inadequate ventilation. Determining the source of pollution is often the first step in improving air quality. Lawrence Livermore National Laboratory’s DNA TRAX, a safe simulant material made with non-biological DNA, can track and quantify indoor airflow.

Laser fusion experiment yield record energy

August 27, 2013 8:25 am | News | Comments

On Aug.13, 2013, Lawrence Livermore National Laboratory's National Ignition Facility (NIF) focused all 192 of its ultrapowerful laser beams on a tiny deuterium-tritium filled capsule. In the nanoseconds that followed, the capsule imploded and released a neutron yield of nearly 3x1015, or approximately 8,000 joules of neutron energy, approximately three times NIF's previous neutron yield record for cryogenic implosions.

Outbreaks such as the severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome coronavirus (MERS) have afflicted people around the world, yet many people think these trends are on the decline. Quite the opposite is true. The efforts to combat this epidemic are being spearheaded by a team of Lawrence Livermore National Laboratory scientists.

Lab researchers achieve record pressure for solid iron

August 9, 2013 9:08 am | News | Comments

Iron is the most abundant element in Earth's core and the sixth most abundant element in the universe. As a key component of terrestrial planets and exoplanets, iron has been one of the most studied materials under extreme conditions. In a series of campaigns using the OMEGA laser at the Univ. of Rochester, researchers compressed iron up to 5.6 million atmospheres, a record pressure for solid iron.

The award will be used to fund their groundbreaking work in both modeling and experiments of a classic plasma configuration, the Z-pinch.

Engineering team makes breakthrough in solar energy research

July 30, 2013 8:46 am | News | Comments

The use of plasmonic black metals could someday provide a pathway to more efficient photovoltaics to improve solar energy harvesting, according to researchers at Lawrence Livermore National Laboratory (LLNL). The LLNL Materials Engineering Div. research team has made breakthroughs experimenting with black metals. These nanostructured metals are designed to have low reflectivity and high absorption of visible and infrared light.

Americans continue to use more renewable energy sources

July 22, 2013 9:12 am | News | Comments

Americans used more natural gas, solar panels and wind turbines and less coal to generate electricity in 2012, according to the most recent U.S. energy charts released by Lawrence Livermore National Laboratory. Natural gas use is up in the electricity generation sector, where it has basically substituted directly for coal, while sustained low natural gas prices have prompted a shift from coal to gas in the electricity generating sector.
