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.

Evaluating nuclear weapons: Sandia Labs taking a modern approach

DOE/Sandia National Laboratories

Sandia National Laboratories is transforming how it assesses nuclear weapons in a stockpile made up of weapons at different stages in their lifecycles -- some systems that have existed for decades alongside those that have undergone life extension programs.

Super plants need super ROOTS

DOE/Sandia National Laboratories
Business Announcement

Researchers from Sandia National Laboratories, The University of New Mexico and the New Mexico Institute of Mining and Technology will adapt previously developed sensors to monitor root function and plant health in new, noninvasive ways

Sandia uses confined nanoparticles to improve hydrogen storage materials performance

DOE/Sandia National Laboratories
Peer-Reviewed Publication

Sometimes, you have to go small to win big. That is the approach a multilab, interdisciplinary team took in using nanoparticles and a novel nanoconfinement system to develop a method to change hydrogen storage properties.

Science versus the 'Horatio Alger myth'

DOE/Los Alamos National Laboratory
Peer-Reviewed Publication

In a new study published today in the journal PLOS ONE, Los Alamos National Laboratory scientists have taken a condensed matter physics concept usually applied to the way substances such as ice freeze, called 'frustration,' and applied it to a simple social network model of frustrated components. They show that inequality of wealth can emerge spontaneously and more equality can be gained by pure initiative.

Sandia using kinetics, not temperature, to make ceramic coatings

DOE/Sandia National Laboratories

Sandia National Laboratories is working on a way to lay down ceramic coatings kinetically and at room temperatures. Coating at room temperature makes microelectronics design and fabrication more flexible and could someday lead to better, less expensive microelectronics components that underpin modern technology.
