Silicon Nanoparticles from the Inside Out: Exploring the Internal Structure of Silicon Nanoparticles and Its Impact on Their Photoluminescence
DownloadFall 2020
Silicon nanoparticles (SiNPs) have garnered significant attention as a biologically compatible alternative to traditional quantum dots. SiNPs are well suited for a wide range of applications due to their photoluminescence (PL) and chemical properties. These advantageous properties can be...

Molecular self-assembly is the basis of structure in Nature. While of far less complexity than a natural system, the same physical rules apply to simple synthetic designed systems that spontaneously form self-assembled structures and patterns. The self-assembly of block copolymers (BCPs) is an...

Fall 2022
The work in this Thesis describes significant progress made in the field of frustrated Lewis pairs (FLPs) at the intersection between modern main group chemistry and materials chemistry. Mainly, this work focuses on the use of an intramolecular phosphine-borane FLP (namely, o-iPr2P(C6H4)BCy2 or...

Fall 2023
Plasmonics deals with the collective excitations of light coupled with free electrons in matter. It has widespread use in the fields of biosensing and nanoscale waveguiding due to the enhancement of the electric fields. My thesis deals with an important frontier in the field of plasmonics by...

Design and synthesis of renewable lipid-based nanocarriers with thermosensitivity for targeted drug delivery applications
DownloadSpring 2024
Numerous drug molecules currently available on the market suffer from short half-life, in vivo instability, poor bioavailability, rapid degradation and inappropriate distribution. While nanocarriers have emerged as a promising solution to address these issues, the primary objective and challenge...

Fall 2017
This thesis will discuss the charge dynamics of dangling bonds (DBs) on the hydrogen terminated Si(100) surface under the effects of temperature and perturbations from local electric fields. The experimental methods are then extended towards DB chains. Electronic time resolved imaging techniques...

Spring 2017
We present the characterization of close-spaced linear dangling bond structures, or dangling bond chains, two to seven dangling bonds long, on a hydrogen terminated silicon (100)-2x1 surface using a scan- ning tunnelling microscope. Constant height differential conductance maps reveal their local...

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...

Spring 2015
Silicon nanocrystals (SiNCs) have been suggested as promising candidates for bioimaging because of their abundance, biocompatibility, and stable photoluminescent properties. However, “naked” SiNCs are insoluble in water and very reactive. As a result, NC surface functionalization is necessary to...

Spring 2014
The impressive developments in the semiconductor industry over the past five decades have largely been dependent on the ability to continually reduce the dimensions of devices on a chip. However, as critical dimension requirements for these devices approach the limits of photolithography, new...
