What are the challenges in measuring mechanical properties?
Measuring the mechanical properties of nanoscale materials, such as stiffness, elasticity, and hardness, is particularly challenging. Traditional mechanical testing methods are not applicable at such small scales. Techniques like nanoindentation and AFM-based force spectroscopy are often used, but they require meticulous calibration and interpretation. Additionally, the mechanical behavior of materials can change at the nanoscale due to surface effects and quantum phenomena.
