What Are Common NDT Techniques Used in Nanotechnology?
Several NDT techniques are employed in nanotechnology to inspect and analyze nanomaterials:
Atomic Force Microscopy (AFM): This technique provides high-resolution surface imaging and can measure mechanical properties at the nanoscale. Scanning Electron Microscopy (SEM): SEM offers detailed images of nanomaterials' surface morphology and can be used to examine minute structural features. X-ray Diffraction (XRD): XRD is used to determine the crystalline structure of nanomaterials, providing insights into their phase composition and crystallinity. Raman Spectroscopy: This technique is useful for identifying molecular compositions and understanding the vibrational modes of nanomaterials. Ultrasonic Testing: Ultrasonic waves help in detecting flaws and measuring the thickness of nanoscale films and coatings.
