Aeroplastic refers to a family of polymeric composites with properties that provide a significant reduction in heat transfer. These composites reduce the thermal conductivity of the base polymer resin between 20%-50% without changing its mechanical properties or modifying the original techniques for processing those polymers....

The primary purpose of this work is to develop and demonstrate technologies to manufacture ultra-low-cost precision optical systems for very large x-ray, UV/optical, or infrared telescopes.

Bearing surfaces are typically either metal-on-metal (MOM), ceramic-on-ceramic (COC), or metal-on-polyethylene (MOP). MOM and MOP couplings have the drawback that metallic or polyethylene particles can sometimes separate from the couplings, which can cause significant problems, particularly in a hip or joint replacement....

A new spray-on material from engineers at The Australian National University (ANU) offers a more robust waterproofing capability than previous coatings. Combining two plastics, one tough and one flexible, the invention could eventually be used to protect mobile phones, de-ice airplane parts, or keep boat...

A low-cost, plastic-based textile from Stanford University engineers could cool the body efficiently when woven into clothing.

M55J/RS-3C resin composite structures on the James Webb Space Telescope (JWST) sunshield will concurrently maintain loads and be exposed to temperature extremes throughout the life of the observatory. Increasing the glass transition temperature (Tg) is...

The Toughened Uni-piece Fibrous Reinforced Oxidation-Resistant Composite (TUFROC) allows for much more affordable and sustainable operations involving Space Launch Services and other systems that utilize Earth re-entry vehicles. TUFROC has an exposed surface design and...

This work involves development of aerogel to be used as a passive absorption media — effectively a concentrator of trace organics — that can be detected by optical techniques. Such a trace organic detection scheme is very different from all...

A unique ultrasonic-based technique has been developed to measure temperature profiles in materials used in thermal protection systems (TPS). The technology requires measurements of the thermal expansion coefficient and the ultrasonic velocity for these materials as a function of temperature in...

In a University of Maryland study, researchers at the A. James Clark School of Engineering have demonstrated that windows made of transparent wood provide more consistent natural lighting and better energy efficiency than glass.

NASA’s Kennedy Space Center (KSC) seeks to license its Advanced Fire Retardant Materials to industry. KSC’s scientists have developed processes and know-how to impart fire retardancy to common polymers such as nylons, polyesters, and...

The current technology for catalytic oxidation of aqueous organic contaminants at elevated temperature and pressure works well at operating conditions of 265 °F and 70 psia with effluent TOCs (total organic carbon) of less than 0.5 ppm. However, it does not perform well at the reduced...
