NASA's Langley Research Center researchers have developed a novel method for making carbon nanotubes that are very uniform in size. A template is used to guide the carbon nanotube growth so that all nanotubes are uniform in size. The carbon nanotubes can be used...

NASA's Langley Research Center has developed an extensive technology portfolio on novel methods for effective dispersion of carbon nanotubes (CNTs) in polymers. The technology portfolio extends from making stable dispersions of CNTs in polymer resins to processes for making composite CNT/polymer films and articles....

NASA's Glenn Research Center invites companies to license or establish partnerships to develop its patented high-temperature, low-melt imide resins for fabrication of automotive components. Produced by a solvent-free melt process, these resins exhibit high glass transition...

Utilizing the full mechanical capabilities of individual nanotubes is a primary research goal in nanotube reinforced nanocomposite materials. Practical use of these nanomaterials requires creating stable and strong linkages between nanotubes without...

NASA Langley Research Center has developed a novel negative dielectric constant material based on ion-conducting materials. A negative dielectric constant material is an essential key for creating metamaterials, or artificial negative index materials (NIMs). NIMs have generated...

Innovators at NASA's Glenn Research Center have developed a number of materials and methods to optimize the performance of nanomaterials by making them tougher, more resistant, and easier to process. Glenn's scientists are generating critical improvements at all stages of...

Innovators at NASA's Glenn Research Center have developed a method for fabricating a fiber-reinforced diamond composite coating on the surfaces of sliding thrust bearings at low and cryogenic temperatures. The...

Material damping is important in the design of structures as it limits vibration amplitudes, increases fatigue life, and affects impact resistance. This is particularly true for composite materials, which are currently used extensively in applications that experience frequent dynamic loading....

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...

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...
