Mechanical & Aerospace Engineering Theses & Dissertations
The atomic force microscope (AFM) is a probe-based microscope that uses nanoscale and structural imaging where high resolution is desired. AFM has also been used in mechanical, electrical, and thermal engineering applications. This unique technique provides vital local material properties like the modulus of elasticity, hardness, surface potential, Hamaker constant, and the surface charge density from force versus displacement curve. Therefore, AFM was used to measure both the diameter and mechanical properties of the collagen nanostraws in human costal cartilage. Human costal cartilage forms a bridge between the sternum and bony ribs. The chest wall of some humans is deformed …

Honors Theses
It is well known that Atomic Force Microscopy imaging is capable of yielding high resolution results with of surfaces at the nanoscale. However, despite the device capabilities and vast applications, AFM microscopy is possibly the most prone to the creation of image artifacts. AFM imaging can easily, and is often, corrupted by various external forces. The most obvious and measurable form of external interference is of course the presence of ambient noise. Most AFM manufactures attempt to counter the effects of such noise on the imaging process through use of noise-proof or noise-resistant shields that cover the microscope aperture. Without …
