Method development for characterizing the hydrophobicity of engineered nanoparticles

Creator:: Lee, Fang Yu
Abstract:: Characterizing the hydrophobicity of nanoparticles can help us understand their fate and transport in the environment, as well as how nanoparticles may interact with biological systems. However, contact angle and partition coefficient have limitations in measuring the hydrophobicity of nanoparticles, thus promising methods to measuring the hydrophobicity of nanoparticles are...

Developing rapid in vivo assays to investigate structure response relationships

Creator:: Truong, Lisa
Abstract:: Incorporation of nanoparticles (NPs) into consumer products is on the rise and human exposure to NPs is unavoidable. Currently, there is insufficient data to assess the safety of nanoparticles. I conducted a series of five studies using the zebrafish model to determine which NP components (i.e., core material or surface...

Organic-solvent resistant ultrafiltration and nanofiltration membrane modules for separation and purification of nanoparticles

Creator:: Kim, Taehyeong
Abstract:: The intriguing size- and shape dependent properties of nanoparticles have garnered recent attention in many science and engineering areas. When the particle size is in the nanometer size range, the material exhibits very different properties such as surface plasmon resonance (of gold nanoparticles) and superparamagnetism (of iron oxide nanoparticles). The...

Zero kinetic energy photoelectron spectroscopy of polycyclic aromatic hydrocarbons

Creator:: Zhang, Jie
Abstract:: In this dissertation, I present electronic spectra of a few polycyclic aromatic hydrocarbons (PAHs): tetracene, pentacene, pyrene, benzo[g,h,i]perylene and benzo[a]pyrene using resonantly enhanced multiphoton ionization (REMPI) and zero kinetic energy (ZEKE) photoelectron spectroscopy. The work of tetracene and pentacene also combine a laser desorption source with a ZEKE spectrometer, demonstrating...

Micro total analysis system for in-situ and autonomous spectrophotometric monitoring of iron in groundwater

Creator:: Koch, Corey R.
Abstract:: We have developed a compact micro total analysis system (μTAS) to serve as a platform for in-situ spectrophotometric water quality monitoring. Individual fluidic, optical, and electrical components were designed, developed, and characterized. These components were combined in both an integrated (single lithographic “chip-based” platform) and a modular manner. The microfluidic...

Controlling the Co-Precipitation of Colloidal PbSe Quantum Dots and Their Device Performance in a Diode Architecture

Creator:: McCrea, Tyler D.
Abstract:: In this work, colloidal PbSe quantum dots (QDs) are shown to be synthesized in a controlled manner by changing the growth time and reaction temperature in a microwave synthesis method. It is explained why quantum dots make such a unique material to create electronic devices and the specific benefits that...

Predicting the Effect of Local Conditions on Metal-oxides: Pt/γ-Al₂O₃ Interface and Degradation of α-Cr₂O₃ Passive Film

Creator:: Oware Sarfo, Kofi
Abstract:: Metal-oxides are very important in industrial applications such as thermal barrier coatings, corrosion protection, and heterogeneous catalysis. The wide variety of applications for metal-oxides are derived from the array of properties of metal-oxides. It is, therefore, important to understand and predict the conditions of synthesis and operation to optimize the...
