1. composed of or containing crystals with dimensions in the nanometer range (typically 1–100 nanometers)
Usage: technical; materials science

Examples

• Nanocrystalline materials exhibit unique mechanical and electrical properties due to their extremely small grain size.
• The researchers developed a nanocrystalline coating that improved the durability of the metal surface.
• Nanocrystalline silicon is used in advanced solar cell technology.
• The nanocrystalline structure of the alloy enhanced its strength without sacrificing flexibility.
• Scientists are exploring nanocrystalline ceramics for high-temperature applications.
