Cu-Ga-S/ZnS Quantum Dots with Silica Melting Gel as a Luminescent Downshifting Coating for Enhancing Solar Photovoltaic Power Generation

Creator:: Chen, Si-Hao
Abstract:: Solar cells, also known as photovoltaic devices, are a class of renewable energy systems that can convert photons into electrons without the carbon dioxide emission. Short-wavelength, high-energy photons in the ultraviolet (UV) range can't be efficiently utilized by most solar cells because of the spectral mismatch. Luminescent downshifting is a...

Understanding Charge and Mass Transfer Phenomena in Functional Oxide Heterostructures

Creator:: Samarakoon, Widitha
Abstract:: Oxides are a versatile class of materials with a wide range of electronic, optical, and magnetic properties. This makes them ideal for use in a multitude of functional devices for oxide electronics, electrochemical conversion, and storage. The overall performance of these devices is governed by atomic scale charge and mass...

Design Principles of Transition Metal X-ide Catalysts for Electrochemical Oxygen Reduction and Evolution Reactions: In-Situ X-ray Spectroscopy Studies

Creator:: Wang, Maoyu
Abstract:: Hydrogen is the green fuel that can be produced from water through electrolysis and used via hydrogen fuel cells to generate electricity with zero carbon dioxide emission. The commercialization of electrolyzers and fuel cells is the critical step to achieving global carbon neutrality. However, it is severely hampered by the...

Multiscale modeling of two-phase flows in microarchitectures with microfeatures

Creator:: Truszkowska, Agnieszka
Abstract:: Two-phase flows in microtechnology based devices are purposefully present in multiphase reactors, phase separators, analytical devices and others. Two-phase flows can also be an undesirable side effect occurring during operation due to phase transitions or, more commonly, introduction of surrounding air through equipment gaps and with process feed. In both...

Effect of cosputtered catalyst on growth and alignment of carbon nanotubes by plasma enhanced chemical vapor deposition

Creator:: Gunderson, Eric P.
Abstract:: The effect of cosputtered catalyst on growth and alignment of carbon nanotubes (CNTs) grown by plasma enhanced chemical vapor deposition (PECVD) was investigated. Aligned CNTs were observed using a cosputtered catalytic metal deposited directly on boro-aluminosilicate glass. Catalytic metal alloys were sputtered directly onto the substrate using magnetron sputtering. Deposition...

The Effect of Oxygen and Salinity Conditions on Soluble Metabolic Product Formation by Methylomicrobium buryatense 5GB1

Creator:: Cameron, Marina R.
Abstract:: Methanotrophic bacteria are promising means of producing value-added products as they have the ability to transform methane under atmospheric temperature and pressure. Efforts to develop methanotrophs to produce value-added products are hoped to incentivize a decrease in methane flaring operations. The data collected during this study was used to inform...

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...

Probing Structure, Selectivity, and Orientation of Biomolecules to Cell Membranes by Sum Frequency Generation

Creator:: Golbek, Thaddeus W.
Abstract:: Cell membranes act as barriers against unwanted movement of ions and biomolecules and are complex surfaces littered with protein channels, ion channels, cholesterol, and a myriad of different proteins. While this surface is extremely well studied, there is still much we do not know. The work in this dissertation demonstrates...

Spherical Au Nanoparticle Interaction with Lipid Monolayers Probed with Sum Frequency Generation Spectroscopy

Creator:: Faase, Ryan A.
Abstract:: Nanoparticles have become more prevalent from their use in sunscreen to antimicrobial agents in socks. In light of these applications, gaining a fundamental understanding of how NPs interact with humans is crucial for their future. Specifically, how cells interact with NPs and what factors drive the modes of cellular uptake....

Near-infrared absorption gas sensing with metal-organic framework on optical fibers

Creator:: Chong, Xinyuan, Kim, Ki-Joong, Li, Erwen, Zhang, Yujing, Ohodnicki, Paul R., Chang, Chih-Hung, and Wang, Alan X.
Abstract:: Despite significant advantages in terms of portability and cost, near-infrared (NIR) gas sensing still remains a great challenge due to its relatively weak overtone absorption from the fundamental vibrational bond absorption at the mid-IR frequency. In this paper, we demonstrated ultra-sensitive NIR gas sensing for carbon dioxide (CO₂) at 1.57...
