Experients may force revision of astrophysical models of the universe

DOE/Sandia National Laboratories
Peer-Reviewed Publication

In a challenge to current astrophysical models of the universe, researchers have found that current estimates of the interiors of so-called ice giant planets within and without the solar system overstate water's compressibility by as much as 30 percent, forcing revisions in estimates of other elements.

Polycrystalline diamond drill bits open up options for geothermal energy

DOE/Sandia National Laboratories
Peer-Reviewed Publication

Nearly two-thirds of the oil we use comes from wells drilled using polycrystalline diamond compact bits, originally developed nearly 30 years ago to lower the cost of geothermal drilling. Sandia and the US Navy recently brought the technology full circle, showing how geothermal drillers might use the original PDC technology, incorporating decades of subsequent improvements by the oil and gas industry.

Light-emitting nanocrystal diodes go ultraviolet

DOE/Los Alamos National Laboratory
Peer-Reviewed Publication

A multinational team of scientists has developed a process for creating glass-based, inorganic light-emitting diodes that produce light in the ultraviolet range. The work, reported this week in the online Nature Communications, is a step toward biomedical devices with active components made from nanostructured systems.

More grapes, less wrath: Hybrid antimicrobial protein protects grapevines from pathogen

DOE/Los Alamos National Laboratory
Peer-Reviewed Publication

Researchers from Los Alamos National Laboratory, University of California at Davis, and the US Department of Agriculture's Agricultural Research Service have created specially engineered grapevines that produce a hybrid antimicrobial protein that can block Xf infection. Their research is published in the current edition of Proceedings of the National Academy of Sciences, "An engineered innate immune defense protects grapevines from Pierce's disease," by Abhaya M. Dandekar, et al.

Sandia seeks better neural control of prosthetics for amputees

DOE/Sandia National Laboratories
Peer-Reviewed Publication

Sandia National Laboratories researchers, using off-the-shelf equipment in a chemistry lab, have been working on ways to improve amputees' control over prosthetics with direct help from their own nervous systems.

Sandia National Laboratories researchers find energy storage 'solutions' in MetILs

DOE/Sandia National Laboratories
Peer-Reviewed Publication

Sandia researchers have developed a new family of liquid salt electrolytes, known as MetILs, that could lead to batteries able to cost-effectively store three times more energy than today's batteries.
