New Sandia balloon-borne infrasound sensor array detects explosions

DOE/Sandia National Laboratories

Danny Bowman, a Sandia National Laboratories geophysicist, launched a fleet of five solar-powered hot air balloons last year. They reached a height of 13 to 15 miles, twice as high as commercial jets, and detected the infrasound from a test explosion. Infrasound is sound of very low frequencies, below 20 hertz, which is lower than humans can hear, and can be used to monitor explosions, including those caused by nuclear tests.

Pioneering smart grid technology solves decades old problematic power grid phenomenon

DOE/Sandia National Laboratories
Business Announcement

Sandia National Laboratories and Montana Tech University have demonstrated an R&D 100 award-winning control system that smooths out inter-area oscillations using new smart grid technology in the western power grid. The new system allows utilities to push more electricity through transmission lines, leading to lower costs for utilities and consumers and greater stability for the grid.

Tweaking quantum dots powers-up double-pane solar windows

DOE/Los Alamos National Laboratory
Peer-Reviewed Publication

Researchers at Los Alamos National Laboraotry are creating double-pane solar windows that generate electricity with greater efficiency and also create shading and insulation. It's all made possible by a new window architecture which utilizes two different layers of low-cost quantum dots tuned to absorb different parts of the solar spectrum. The approach complements existing photovoltaic technology by adding high-efficiency sunlight collectors to existing solar panels or integrating them as semitransparent windows into a building's architecture.

Sandia computer modeling aids solder reliability in nuclear weapons

DOE/Sandia National Laboratories
Business Announcement

Solder isn't the first thing that comes to mind as essential to a nuclear weapon. But since weapons contain hundreds of thousands of solder joints, each potentially a point of failure, Sandia National Laboratories has developed and refined computer models to predict their performance and reliability.

Sandia researchers make solid ground toward better lithium-ion battery interfaces

DOE/Sandia National Laboratories
Peer-Reviewed Publication

Research at Sandia National Laboratories has identified a major obstacle to advancing solid-state lithium-ion battery performance in small electronics: the flow of lithium ions across battery interfaces.

Los Alamos research fundamental to first efficacy study for mosaic HIV-1 preventive vaccine

DOE/Los Alamos National Laboratory
Business Announcement

Just in time for World AIDS Day (Dec. 1) international partners are announcing the first efficacy study for an investigational HIV-1-preventive 'mosaic' vaccine. Janssen Pharmaceutical Companies of Johnson & Johnson are joining forces with The Bill & Melinda Gates Foundation and National Institutes of Health on this study, and they have enlisted the aid of top researchers worldwide to conduct the trial.
