Several properties can be altered at the nanoscale, including but not limited to:
Mechanical Properties Nanomaterials often exhibit enhanced mechanical properties such as increased strength, hardness, and elasticity. For example, carbon nanotubes are known for their exceptional tensile strength and stiffness.
Electrical Properties The electrical properties of materials can also change at the nanoscale. For instance, graphene has remarkable electrical conductivity, making it a promising material for electronic applications.
Optical Properties Nanoscale materials can have unique optical properties, such as altered emission and absorption spectra. Quantum dots, for example, can emit light of various colors depending on their size, which is useful in display technologies and medical imaging.
Thermal Properties Nanomaterials can exhibit enhanced thermal properties, such as increased thermal conductivity or improved heat resistance. Materials like nanowires can be used in thermal management applications due to their efficient heat transfer capabilities.
