Atomic Force Microscopy Characterization of Hydrogen Terminated Silicon (100) 2x1 Reconstruction
DownloadFall 2015
Non-contact Atomic Force Microscopy (NC-AFM) is a Scanning Probe Microscopy tool offering unique non-perturbative analysis of surfaces and adsorbates at the atomic scale. AFM precisely oscillates a sharp tip above a sample. By monitoring the shift in resonance frequency of a quartz tuning fork...

High aspect ratio microelectromechanical structures have been found, in the literature, to collapse due to capillary forces of liquids. In this dissertation, mathematical models are developed to study (i) the collapse of a microstructure represented by a double cantilevered beam (DCB) with a free...

Dependence of the Interfacial Adhesion between Two Different Types of Material on their Electron Work Function and Electrical Conductivity
DownloadFall 2021
We observed and investigated a novel interfacial phenomenon related to the dependence of interfacial bonding or adhesive force (Fad) between two substances on the difference in their Electron Work Functions (EWF) or Δφ, and developed a model to quantify such a dependence. First, using...

Ultrasound imaging has great potential in intraoral diagnosis, due to its portability, low cost, and low safety risks. A couplant is normally placed between transducers and tissues for better ultrasound image quality. If applied intraorally, the couplants should possess good stability in water,...

Examination of the Regulation of Phosphorylation Events in Macrophage Adhesion and Response to Zymosan
DownloadFall 2012
Macrophages play a central role in innate immunity, most notably in tissue repair, phagocytosis of dead or infected cells, secretion of chemokine and cytokines at sites of infection, as well as the activation of other immune cells. These roles are highly dependent on their capacity to migrate...

Experimental Investigation on Interfacial and Surface Phenomena of Clathrate and Semi-clathrate Hydrates
DownloadFall 2023
Clathrate hydrates are compounds where guest molecules are trapped in cages formed between water molecules via hydrogen bonding. They have many promising applications, such as gas storage, energy storage, gas mixture separation and seawater desalination. They may also form inside the oil & gas...

Exploring Atomic Force Microscopy To Probe Charge Transport Through Molecular Films And For The Development Of Combinatorial Force Microscopy
DownloadFall 2012
Since the invention of the atomic force microscope (AFM), this technology has had profound implications in the study of material science and molecular biology. The ability to visualize and perform quantitative analysis of the nanoscale properties of surfaces has provided great insights into...
