NASA Earth at Night Video

Have you ever wondered what the Earth looks like at night? NASA provides a clear, cloud-free view of the Earth at night using the Suomi National Polar-orbiting Partnership Satellite. The satellite utilizes an instrument known as the Visible Infrared Radiometer Suite (VIIRS), which allows the satellite to capture images of a “remarkably detailed view of [...]

Sandian Served as President of the National Institute of Ceramic Engineers

During FY12, (Electrical, Optical, & Nano Materials Department in Materials Science & Engineering) served as the President of the National Institute of Ceramic Engi­neers, a Class of the American Ceramic Society (ACerS) that represents the ceramic materials community for accreditation† and licensure‡ activities. During the same period, Geoff also served in a related but expanded [...]

Sandia Expertise Guides New Photovoltaic Requirements

Sandia’s Photovoltaic (PV) Arc-Fault Detec­tion and Mitigation team has gained worldwide renown as a leader in the science of PV arc faults. As a driver of groundbreaking experimental and numerical simulations in this area, codes and standards bodies have called on Sandia to improve requirements for arc-fault cir­cuit interrupters. Sandia has advised the National Electrical [...]

Solar Test Facility Upgrades Complete, Leading to Better Sandia Capabilities to Support Power Industry

A recent overhaul of the DOE’s National Solar Thermal Test Facility (NSTTF), operated by Sandia, is dramatically improving researchers’ ability to understand and use concentrating solar power (CSP). The $17.8M upgrade to the NSTTF adds state-of-the-art test capabilities, and the resulting research is expected to lead to more solar power use on the electric grid. [...]

Sandia Demonstrated First-Time, Single-Mode Lasing in Gallium-Nitride Nanowire Lasers

Semiconductor nanowire lasers have attracted intense interest as promising compact, low-power coherent light sources for on-chip applications, many of which (e.g., imaging, multiplex communica­tion, data storage) desire high beam quality and spectral purity—conditions that can be satisfied by single-mode operation in nanowire lasers. However, due to the lack of mode-selection mechanisms, most reported nanowire lasers exhibit [...]
