Coatings & Adhesives

This technology was developed to address the limitations of traditional, single-fed linear alternators that require permanent magnets, adhesive bonding organics, and heavy iron laminations for flux control. They experience eddy-current losses and require electromagnetic interference protection. Furthermore,...

University of Michigan researchers have developed a coating that they believe could lead to the achievement of a long-time goal: Ice-proofing airplanes.

Even tiny cracks can cause bridges to collapse, pipelines to rupture, and fuselages to detach from airplanes due to hard-to-detect corrosion in tiny cracks, scratches, and dents. A new coating strategy for metal self-heals within seconds when scratched, scraped, or cracked. The novel material could prevent tiny...

Small unmanned aircraft systems (UAS), also known as micro air vehicles, are promising tools for a variety of military and commercial applications. Some small UAS have flexible wings and are lightweight, making them back-packable and easy to deploy. Most UAS that are currently...

Lignin is the material left over from the processing of biomass. It gives plants rigidity and also makes biomass resistant to being broken down into useful products. Researchers combined a melt-stable hardwood lignin with conventional plastic, a low-melting nylon, and carbon fiber to...

NASA's Langley Research Center has developed a new low-temperature method of SiGe/sapphire growth that produces the same single-crystal films with much less thermal loading effort to the substrate. This eliminates the time-consuming and costly high heating, long thermal soak times, and interfacial Si layer....

Electromagnetic interference (EMI) can harm smartphones, tablets, chips, drones, wearables, aircraft, and human health. EMI is increasing with the explosive proliferation of devices that generate it. A technique was developed to produce relatively low-cost EMI-blocking composite films.
