Metal-air batteries can be used in a variety of applications ranging from range extenders for electric vehicles to emergency power systems. Metal-sea-water batteries are primarily used for underwater applications ranging from torpedoes to underwater unmanned vehicles. A team of researchers at the...

When combined with saltwater, rust can be a source of electricity.

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...

To produce power more efficiently and cleanly, the next generation of power turbines will have to operate at extreme temperatures and pressures. Currently, single-crystal, nickel-based superalloys are used in such extreme environments. MCrAlY coatings (where M = Co, Ni, or...

Oxide coatings deposited in Glenn Research Center's Plasma Spray-Physical Vapor Deposition (PS-PVD) facility can be processed to be mechanically tough (erosion-resistant) and electrically conductive at room temperature. The electrically conductive phase...

A new class of polymeric materials was developed with resistance to heat, dielectric breakdown, and oxidation at high temperatures. For applications that demand high temperature resistance coupled with greater strength, these polymers can be easily transformed into ceramics with...
