'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.

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.

Perovskite edges can be tuned for optoelectronic performance

DOE/Los Alamos National Laboratory
Peer-Reviewed Publication

In the eternal search for next generation high-efficiency solar cells and LEDs, scientists at Los Alamos National Laboratory and their partners are creating innovative 2-D layered hybrid perovskites that allow greater freedom in designing and fabricating efficient optoelectronic devices. Industrial and consumer applications could include low cost solar cells, LEDs, laser diodes, detectors, and other nano-optoelectronic devices.

Guiding light: Sandia creates 3-D metasurfaces with optical possibilities

DOE/Sandia National Laboratories
Peer-Reviewed Publication

The new Sandia metamaterials can be fabricated in multiple layers to form complex, three-dimensional meta-atoms that reflect more light than shiny gold surfaces, usually considered the ultimate in infrared reflectivity. The III-V materials also emit photons when excited -- something that silicon, which can reflect, transmit and absorb -- can't do.

Plants at the pump

DOE/Sandia National Laboratories
Business Announcement

Regular, unleaded or algae? That's a choice drivers could make at the pump one day. Toward that goal, Sandia National Laboratories is testing strains of algae for resistance to a host of predators and diseases, and learning to detect when an algae pond is about to crash.

Sandia scientist named fellow for diverse contributions to aeronautics, space research

DOE/Sandia National Laboratories
Grant and Award Announcement

Gary Polansky, the chief scientist for hypersonic technology development and applications at Sandia National Laboratories, has been named a fellow of the American Institute of Aeronautics and Astronautics (AIAA).

Exploring the evolution of nuclear deterrence through interviews, historical footage

DOE/Sandia National Laboratories

Sandia National Laboratories explores the evolution of nuclear deterrence in a new documentary that combines modern and historical footage with a wide range of interviews. On Deterrence features interviews with former secretaries of defense, general officers, policymakers, analysts, scholars and scientists with varied viewpoints to describe the impact of nuclear deterrence since the end of World War II.
