Nanoscale engineering boosts performance of quantum dot LEDs

October 25, 2013 11:09 am | News | Comments

Quantum dots are nano-sized semiconductor particles whose emission color can be tuned by simply changing their dimensions. New research at Los Alamos National Laboratory aims to improve quantum dot-based light-emitting diodes by using a new generation of engineered quantum dots tailored specifically to have reduced wasteful charge-carrier interactions that compete with the production of light.

Water for future Mars astronauts?

September 27, 2013 7:55 am | News | Comments

Within its first three months on Mars, NASA’s Curiosity Rover saw a surprising diversity of soils and sediments along a half-kilometer route that tell a complex story about the gradual desiccation of the Red Planet. Perhaps most notable among findings from the ChemCam team is that all of the dust and fine soil contains small amounts of water.

Report: Quality of science, engineering at National Security Labs is solid

September 11, 2013 11:38 am | News | Comments

The science and engineering capabilities that underpin the nuclear weapons stockpile stewardship and nonproliferation missions at the nation’s three national security laboratories are “healthy and vibrant,” says a new report from the National Research Council.  The committee that wrote the report found no problems with the quality of science and engineering that would prevent certification of the stockpile.

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.

Rapid Scanning for Radiological Threats

August 29, 2013 11:57 am | Award Winners

The Earth’s upper atmosphere is under bombardment by cosmic radiation that produces showers of pions, which rapidly decay into a constant flux of muons (some 200 m2/sec) that shower objects on Earth. Since the muon angular trajectory changes as a function of the density and atomic weight of the material traversed, a unique “signature” for the substance can be developed. The ability to identify distinct material density enables the Multi-Mode Passive Detection System (MMPDS), developed by Decision Sciences International Corp. and Los Alamos National Laboratory, to quickly detect unshielded to heavily shielded nuclear threats, as well as gamma rays, with near-zero false alarms.

Nuclear Energy in Space

August 28, 2013 9:51 am | Award Winners
