Mind-Blowing: Metal That Heals Itself!
2025-06-22
Scientists have observed a damaged section of platinum metal repairing itself at the nanoscale! During fatigue testing using a specialized microscope, a 40-nanometer-thick platinum wafer, repeatedly stressed, showed cracks spontaneously fusing and healing after about 40 minutes. This unexpected finding challenges conventional materials science and opens doors to revolutionary self-healing materials for everything from bridges and engines to smartphones. While currently observed only under vacuum conditions at the nanoscale, the discovery offers immense potential for future engineering breakthroughs.
