Fall 2013
Gypsum supersaturation in process water is known to have detrimental effects on flotation performance of sulphide minerals. The motivation of this research is to develop a better understanding of the impact of gypsum supersaturation in process water on sphalerite flotation. For this purpose, this...

Spring 2011
In this thesis, measurement and analysis of colloidal forces between an atomic force microscope (AFM) probe and a topographically patterned substrate are reported. The energy between the patterned substrate and a smooth flat plate was characterized mathematically using Surface Element Integration...

Interfacing Silicon-Based Quantum Dots with Proteins for Biological and Sensing Applications
DownloadFall 2020
This dissertation presents the preparation of functional bioinorganic hybrids from silicon-based quantum dots (SiQDs) and enzymes and the use of SiQDs and green fluorescent protein as ratiometric photoluminescent sensors for nerve agents. Chapter 2 discusses the preparation of water-soluble...

Nanolithography on H:Si(100)-(2 x 1) using combined Scanning Tunneling Microscopy and Field Ion Microscopy techniques
DownloadFall 2011
This thesis reports on the combined techniques of ultra-high vacuum scanning tunneling microscopy (UHV-STM) and field ion microscopy (FIM). The apex structure of STM scanning tips correlates with their ability to yield highly-resolved images and to perform accurate hydrogen desorption on...

Observing and Manipulating Single Electrons Confined to Silicon Dangling Bond Ensembles with Non-Contact Atomic Force Microscopy
DownloadFall 2018
Non-contact atomic force microscopy (nc-AFM) is capable of inducing and resolving single-electron charge transitions of surface adsorbates. Here, these techniques are extended by studying the charge configurations of dangling bond (DB) ensembles on the hydrogen-terminated silicon surface. nc-AFM...
