Thermal stress is critical in nanotechnology for several reasons:
Thermal Expansion Coefficient: Nanomaterials often have different thermal expansion coefficients compared to their bulk counterparts, leading to mismatches in expansion and contraction. Heat Dissipation: The ability to dissipate heat is limited at the nanoscale, which can result in localized hotspots and stress. Mechanical Properties: The mechanical properties of materials can change dramatically at the nanoscale, making them more susceptible to thermal stress.
