Solar ‘gardens’ let communities share renewable power

In northern New Mexico the sun shines nearly every day of the year. If solar energy is going to be viable anywhere, it will be here—and a small electric cooperative in historic Taos is taking advantage of it. Kit Carson Electric Cooperative is offering its customers the opportunity to buy solar energy from “plots” in a “garden” of solar power generation.           

The cooperative has solar power projects with Los Alamos National Laboratory, beginning with a project that provides electric energy for the Taos campus of the University of New Mexico. (Full Story)

A golden anniversary for space-based treaty verification

Fifty years ago this month, Los Alamos National Laboratory sensor technology lifted off into space to help verify that world Superpowers were abiding by the newly signed Limited Test Ban Treaty-a pledge by the United States, the former Soviet Union and the United Kingdom to refrain from testing nuclear weapons in the atmosphere, underwater or in space.

"For the past 70 years, Los Alamos National Laboratory has serviced the country and provided technical solutions to the some of biggest national security challenges facing the nation," said Terry Wallace, Principal Associate Director for Global Security at Los Alamos. (Full Story)

The National Nuclear Security Administration (NNSA) Tuesday announced that it has awarded 18 Sustainability Awards for innovation and excellence to its national laboratories and sites.        

Los Alamos National Laboratory won four awards for work in DNA, greenhouse gases, environmental sustainability and energy management. (Full Story)

Nanoscale engineering boosts performance of quantum dot light emitting diodes

Dramatic advances in the field of quantum dot light emitting diodes (QD-LEDs) could come from recent work by the Nanotechnology and Advanced Spectroscopy team at Los Alamos National Laboratory.

Quantum dots are nano-sized semiconductor particles whose emission color can be tuned by simply changing their dimensions. They feature near-unity emission quantum yields and narrow emission bands, which result in excellent color purity. (Full Story)

Nanostructures offer way to control quantum effect

Researchers measured the Casimir attraction between a metallic grating and a gold coated sphere. NIST image.

Prevailing theory does a good job describing the Casimir force between featureless, flat surfaces and even between most smoothly curved surfaces. However, according to researchers existing theory fails to predict the interactions they observed in their experiment.

This work was performed in collaboration with scientists from Los Alamos National Laboratory; the Univ. of Maryland, College Park; Argonne National Laboratory; and Indiana Univ. – Purdue Univ. (Full Story)

Nuclear cleanup project could be model for other sites

A Soviet-era nuclear test site in Kazakhstan was cleaned up through a collaborative international project that could provide lessons for tackling other dangerous nuclear sites across the globe

Nuclear scientists from Los Alamos National Laboratory, a US nuclear research institution, first met their Kazakh and Russian counterparts in 1992 following the Soviet Union’s collapse. (Full Story)
