Methodology for the Effective Stabilization of Tin-Oxide-Based Oxidation/Reduction Catalysts

NASA Langley researchers, in work spanning more than a decade, have developed a portfolio of technologies for low-temperature gas catalysis. Originally developed to support space-based CO2 lasers, the technology has evolved into an array of performance capabilities and processing approaches, with potential applications ranging from indoor air filtration to automotive catalytic converters and industrial smokestack applications. The technology has been used commercially in systems that provide clean air to racecar drivers, as well as incorporated into commercially available filtration systems for diesel mining equipment. Backed with extensive research on these technologies, NASA welcomes interest in the portfolio for other commercial and industrial applications.

Polymer-Reinforced, Non-Brittle, Lightweight Cryogenic Insulation for Reduced Lifecycle Costs

The objective of this project was to develop inexpensive structural cryogenic insulation foam that has increased impact resistance for launch and ground-based cryogenic systems. Two parallel approaches were used: a silica-polymer co-foaming technique and a post-foam coating technique. Structures were fabricated using both techniques to formulate insulation for the specified applications. The insulation will survive in space and terrestrial environments, provide a good moisture barrier, and exhibit thermal insulation properties.

Researchers Awaken Graphene's Hidden Superconductivity

Since its discovery in 2004, scientists have believed that graphene contained an innate ability to superconduct. Now researchers from the University of Cambridge have found a way to activate that previously dormant potential, enabling the material to carry an electrical current with zero resistance.
