NASA’s Marshall Space Flight Center innovators have developed several new designs and methods of fabrication for composite and composite-overwrapped tank vessels that help significantly improve their structural integrity against impact, abrasion, harsh environments, and fire. Several...

Innovators at NASA’s Glenn Research Center have created exciting new developments in thermal barrier coatings, both in the chemical compositions of the coatings and in the process by which they are applied. NASA’s researchers have developed a revolutionary bond coat system that improves the...

Motivated by public hazards associated with contaminated sources of drinking water, a group of scientists has successfully developed and tested tiny, glowing crystals that detect and trap heavy-metal toxins like mercury and lead.

While most solid materials expand with heat, a new 3D-printed structure built by Massachusetts Institute of Technology (MIT) engineers is designed to shrink. The metamaterial may enable heat-resistant circuit boards.

Virginia Tech researchers have produced flexible solar panels that can become part of window shades or wallpaper. The material will capture light from the sun as well as light from sources inside buildings.

New insulative carbon-fiber composite systems have been developed for use in structural and thermal applications for the aerospace vehicle interface. The sandwich-type composite structure, including carbon fiber and aerogel blanket materials, is based on the previously disclosed family of...

Minimally invasive and non-invasive therapeutic ultrasound treatments can be used to ablate, necrotize, and/or otherwise damage tissue. High-intensity focused ultrasound (HIFU), for example, is used to thermally or mechanically damage tissue....

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....

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.

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....

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.
