Diamonds Repair Themselves: Self-healing at Room Temperature

Researchers at Beihang University have observed self-healing in synthetic diamonds at room temperature. By creating nanotwinned diamond composites (ntDC) and inducing cracks, the team found that the presence of specific carbon atoms allowed for healing as they bonded with each other. The healed samples exhibited a tensile strength of 34%. This discovery could lead to the development of more durable diamonds for various applications.
