Self-Healing, Fluid-Inspired Material

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...
