How Do Temperature Fluctuations Affect Nanomaterials?
Temperature fluctuations can impact nanomaterials in several ways:
1. Thermal Expansion: Nanomaterials may expand or contract more significantly than bulk materials due to their high surface-area-to-volume ratio. 2. Phase Transitions: Some nanomaterials can undergo phase transitions (e.g., from solid to liquid) at different temperatures compared to bulk materials. 3. Electronic Properties: Temperature changes can affect the electron mobility and bandgap of semiconductor nanomaterials. 4. Mechanical Properties: Nanomaterials may become more brittle or ductile with temperature changes.
