The superior light-emitting properties of quantum dots can efficiently harvest sunlight and enhance solar energy, according to researchers from Los Alamos National Laboratory, in collaboration with the University of Milan-Bicocca, who say this could lead to development of windows that double as solar panels.

A house window that doubles as a solar panel could be on the horizon, thanks to recent quantum-dot work. Scientists have demonstrated that superior light-emitting properties of quantum dots can be applied in solar energy by helping more efficiently harvest sunlight.

"The key accomplishment is the demonstration of large-area luminescent solar concentrators that use a new generation of specially engineered quantum dots," said lead researcher Victor Klimov." (Full Story)

Los Alamos researchers and collaborators have used nondestructive imaging techniques to study the solidification of metal alloy samples. The team used complementary methods of proton radiography at the Los Alamos Neutron Science Center and synchrotron x-ray radiography at Argonne National Laboratory to make the measurements. This is the first time that high-energy protons have been used to nondestructively image a large metal sample during melting and solidification. (Full Story)

Scientists verify world’s largest single crystal piece of gold

Scientists at Los Alamos National Laboratory have confirmed a 7.68 oz (217.78 g) piece of gold is in fact a singular crystal increasing its value from around $10,000 to an estimated $1.5 million.

The specimen, the largest single crystal piece of gold in the world, was discovered in Venezuela decades ago, but it is only by using advanced probing instruments that experts can now verify its authenticity. (Full Story)

STEM conference promotes careers for young women

Speaking at Expanding Your Horizons in Cimarron, Sanna Sevato said five years ago she found a job opportunity at the Los Alamos National Lab, and she has lived there ever since. She describes this as her “dream job.”

This yearly conference is held to make young women more aware of the different career paths that are available in the science, technology, engineering, and math fields. (Full Story)

New shared lab is big opportunity for small biotech startups

Funding for the lab came from the city of Santa Fe and the Los Alamos lab and a $1.25 million grant from the federal Economic Development Administration.

The final piece of lab equipment bought for the BioScience Laboratory is an acoustic cytometer developed in part at the Santa Fe Business Incubator by former Los Alamos  National Laboratory scientist John Elling. (Full Story)

Prioritizing data in the age of exascale

By now, most HPCers and the surrounding community are aware that data movement poses one of the most fundamental challenges to post-petascale computing.

Around the world exascale-directed projects are attempting to maximize system speeds while minimizing energy costs. The most expensive operation: data movement. So says  James Ahrens of Los Alamos National Laboratory. (Full Story)

Los Alamos guns take aim at material’s mysteries
