Predicting the limits of friction: Sandia looks at properties of material

DOE/Sandia National Laboratories
Peer-Reviewed Publication

Sandia National Laboratories materials scientists have developed a model to predict the limits of friction behavior of metals based on materials properties -- how hard you can push on materials or how much current you can put through them before they stop working properly.

Ultrafast measurements explain quantum dot voltage drop

DOE/Los Alamos National Laboratory
Peer-Reviewed Publication

Solar cells and photodetectors could soon be made from new types of materials based on semiconductor quantum dots, thanks to new insights based on ultrafast measurements capturing real-time photoconversion processes.

Breaking the supermassive black hole speed limit

DOE/Los Alamos National Laboratory
Peer-Reviewed Publication

A new computer simulation helps explain the existence of puzzling supermassive black holes observed in the early universe. The simulation is based on a computer code used to understand the coupling of radiation and certain materials.

New brain-inspired cybersecurity system detects 'bad apples' 100 times faster

DOE/Sandia National Laboratories
Business Announcement

The Neuromorphic Cyber Microscope can look for the complex patterns that indicate specific 'bad apples,' all while using less electricity than a standard 60-watt light bulb, due to its brain-inspired design.

Less radiation in inner Van Allen belt than previously believed

DOE/Los Alamos National Laboratory
Peer-Reviewed Publication

The inner Van Allen belt has less radiation than previously believed, according to a recent study in the Journal of Geophysical Research. Observations from NASA's Van Allen probes show the fastest, most energetic electrons in the inner radiation belt are actually much rarer and harder to find than scientists expected. This is good news for spacecraft that are orbiting in the region and can be damaged by high levels of radiation.

'Flying saucer' colloidal quantum dots produce brighter, better lasers

DOE/Los Alamos National Laboratory
Peer-Reviewed Publication

A multi-institutional team of researchers from Canada and the US has demonstrated steady state lasing with solution-processed nanoparticles called 'colloidal quantum dots,' an important step on the path to improving laser tools for fiber optics, video projectors and more accurate medical testing technology. The work is reported today in a paper for the journal Nature.

Power partners: Sandia draws industry into quest for cheaper, cleaner electricity

DOE/Sandia National Laboratories
Business Announcement

Sandia National Laboratories is working with three industry partners to commercialize a distributed power system that can produce cheaper, cleaner, more efficient electricity.

Testing for Zika virus: There's an app for that

DOE/Sandia National Laboratories
Peer-Reviewed Publication

Add rapid, mobile testing for Zika and other viruses to the list of things that smartphone technology is making possible. Researchers at Sandia National Laboratories have developed a smartphone-controlled, battery-operated diagnostic device that weighs under a pound, costs as little as $100 and can detect Zika, dengue and chikungunya within 30 minutes.

Dan Sinars represents Sandia in first energy leadership class

DOE/Sandia National Laboratories
Grant and Award Announcement

Dan Sinars, a senior manager in Sandia National Laboratories' pulsed power center, which built and operates the Z facility, is the sole representative from a nuclear weapons lab in a Department of Energy leadership program that recently visited Sandia.

Unexpected oxidation state for molecular plutonium discovered

DOE/Los Alamos National Laboratory
Peer-Reviewed Publication

Researchers at Los Alamos National Laboratory in collaboration with the University of California - Irvine (UCI) have uncovered a significant new chemical attribute of plutonium, the identification and structural verification of the +2 oxidation state in a molecular system.
