Materials & Components Compatibility

The materials and components compatibility program element applies Sandia’s core capability in hydrogen embrittlement to address fundamental questions about the mechanical behavior of materials when exposed to high-pressure gaseous hydrogen. The cornerstone of Sandia’s core capability in hydrogen embrittlement is the Hydrogen Effects on Materials Laboratory where specialized assets reside for conducting mechanical testing of […]

Light Creation Materials

Light Creation Materials
Different families of inorganic semiconductor materials can contribute to solid-state white lighting. The primary chemical systems used for LEDs are Group-III nitrides and Group-III phosphides. It is, however, possible that breakthroughs in a different material system, for example ZnO, will be important.

AlGaInN Materials
LEDs based on gallium nitride (GaN) and ternary alloys with indium […]

White Light Creation Architectures

The entire spectral range of visible light can be produced by III-V semiconductor LEDs. AlGaInP LEDs can cover the spectral range from red to amber, and their commercial production is relatively mature. AlGaInN LEDs are the prime candidates for producing wavelengths from blue to yellow. Two main approaches for producing white light are being pursued:This […]

Lignocellulosic Biomass

Lignocellulosic biomass is one of the most abundant plants on Earth and is a critical feedstock for the production of renewable fuels. Lignocellulose is a mixture of complex sugars and lignin, a non-carbohydrate polymer that provides strength and structure to plant cell walls. By extracting simple fermentable sugars from lignocellulose and producing biofuels, the potential […]
