Part A
Write two importance of Bio and Nanomaterials.
Answer
Bio-nanomaterials are crucial for targeted drug delivery and enhanced biocompatibility in medical implants, allowing for precise interaction with biological systems at the cellular level.
What is the importance of Sound Wave Impedance?
Answer
Sound wave impedance is essential for characterizing the mechanical properties and structural integrity of nanomaterials. It determines how acoustic energy propagates through a medium, which is critical for non-destructive testing and evaluating the elastic modulus of thin films and nanostructures.
