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...

AN ABSTRACT OF THE THESIS OF Fang Yu Lee for the degree of Master of Science in Chemical
Evaluation of amorphous oxide semiconductors for thin film transistors (TFTs) and resistive random access memory (RRAM) applications

Creator:

Rajachidambaram, Jaana Saranya

Abstract:

Thin-film transistors (TFTs) are primarily used as a switching element in liquid crystal displays. Currently, amorphous silicon is the dominant TFT technology for displays, but higher performance TFTs will become necessary to enable ultra-definition resolution high-frequency large-area displays. Amorphous zinc tin oxide (ZTO) TFTs were fabricated by RF magnetron sputter...

Investigation of oxide semiconductor based thin films : deposition, characterization, functionalization, and electronic applications

Creator:

Rajachidambaram, Meena Suhanya

Abstract:

Nanostructured ZnO films were obtained via thermal oxidation of thin films formed with metallic Zn-nanoparticle dispersions. Commercial zinc nanoparticles used for this work were characterized by microscopic and thermal analysis methods to analyze the Zn-ZnO core shell structure, surface morphology and oxidation characteristics. These dispersions were spin-coated on SiO₂/Si substrates...

Low-temperature, Inkjet-printed p-Type Copper(I) Iodide-based Thin-Film Transistors

Creator:

Gorecki, Jenna Y.

Abstract:

Inkjet-printed p-type copper(I) iodide-based TFTs were successfully fabricated. As-printed copper(I) halide semiconductor films, such as CuI, CuBrI, and CuClI, were used as p-type active channel layers for TFTs. The entire process of the TFTs fabrication was maintained under 150 °C, which is compatible with flexible plastic substrates and transparent glass...

Batch and Continuous Flow Column Studies of Methane Consumption and Methanol Production by Methylosinus Trichosporium OB3b and Methylomicrobium Buryatense 5GB1 Immobilized In Ca-Alginate and Agarose Hydrogels

Creator:

Molzahn, Paige

Abstract:

Two methanotrophs, M. trichosporium OB3b and M. buryatense 5GB1, were encapsulated using two methods to investigate the potential of methane conversion for biofuel production. Ca-alginate and low melt agarose were used to immobilize the methanotrophs for batch and continuous flow column testing. Varying protein concentrations, residence times, and immobilization methods...

An in silico Approach to Determine the Influence of Surface Chemical Properties on the Toxicity of Engineered Zinc Oxide Nanoparticles

Creator:

Zhou, Zitao

Abstract:

Nanotechnology products have long since made their way to markets around the world increasing the concerns about whether nanomaterials pose a risk to our environment or health. It has been suggested that engineered nanomaterial (ENM) with broad applications and rapid commercialization need better risk assessment and regulation. However, the refinement...

Characterization of CoGe Thin Films and Powders

Creator:

Pfau, Andrew James

Abstract:

Cobalt germanides have been widely studied as semiconductor contact materials, but recent theoretical studies suggest that they may also be excellent catalysts for methane steam reforming with stabilities and activities comparable to noble metal catalysts. In order to study the catalytic activity of cobalt germanides, it is critical to first...

Solution-based deposition of functional thin films : development of a glucose biosensor and thermal processing of CZTS nanoparticle films

Creator:

Durgan, Christopher J.

Abstract:

The development of solution-based methods for deposition of different thin film material is presented as an alternative to high cost vacuum-based methods. For certain materials, vacuum techniques are unsuitable for processing. Additionally, vacuum-based processes present high capital costs associated with equipment, and slow processing times. Atmospheric pressure solution based techniques...

Ultrafiltration Membrane Fouling in Side-stream Aerobic Granular Sludge Membrane Bioreactor

Creator:

Yang, Zhengjian

Abstract:

The integration of low-pressure membrane filtration and aerobic granular sludge (AGS) reactor leads to a novel environmental biotechnological process with strong potential to overcome membrane fouling and demonstrate excellent wastewater treatment performance. However, membrane fouling mechanisms in the AGS based membrane bioreactor (MBR) are lack of systematic elaboration. In the...

Continuous flow synthesis of lead sulfide and copper indium diselenide nanocrystals

Creator:

Knapp, Michael W.

Abstract:

The use of size and shape tunable quantum confinement nanocrystals has many potential applications for use in semiconductors, optics and sensors. The synthesis of lead sulfide (PbS) and copper indium diselenide (CuInSe₂) nanoparticles are of particular interest for use in semiconductor, optoelectronics and bio-medical applications. The continuous synthesis of lead...
