Copper and iron chalcogenides for efficient solar absorption

Creator:: Platt, Heather A. S.
Abstract:: This dissertation outlines two approaches for improving the efficiency and reducing the cost of photovoltaic energy generation. First, the structures of known binary copper and iron compounds are used to choose the promising compositions Fe₂XS₄ (X = Si, Ge), Cu₃TaQ₄ (Q = Se, Te), and BaCuQ'F (Q' = S, Se,...

A study of climbing-film flow characteristics of various liquids and air in an annular duct

Creator:: Vierra, George Joseph
Abstract:: Momentum transfer in climbing-film flow in an annular duct was investigated. Air and various liquids, with a wide range of viscosities and surface tensions, were investigated. The two phases flowed co-currently upward, the liquid climbing as a thin film on the inner wail while the outer wall remained dry. The...

Characterization and Investigations of Thin-Film Materials with X-ray Photoelectron Spectroscopy

Creator:: Diulus, J. Trey
Abstract:: Surface characterization of materials is widely utilized over a range of disciplines and essential to the development of new materials, technology, or processes. Metal oxide nanoclusters have shown promise as potential new generation photoresist materials for extreme ultraviolet (EUV) nanolithography. Organotin clusters have been proposed as potential candidates for resist...

Nanotechnology for solar module applications : zinc oxide nanostructures and anti-reflective coating modeling, deposition, analysis, and model fitting

Creator:: Han, Katherine M.
Abstract:: To become a competitor for fossil fuels such as coal, solar installations will need to be produced and installed at a price equal to or below grid parity. This price can be approached by either reducing the overall system cost or increasing system efficiency. The focus of this paper is...

Investigation of Iron Passivity and Chloride-induced Depassivation in Alkaline Electrolytes using Reactive Force Field Molecular Dynamics (ReaxFF-MD)

Creator:: Dormohammadi, Hossein
Abstract:: The corrosion and passivity of iron (and carbon steel) in media with different alkalinity as well as iron depassivation have been studied extensively using electrochemical methods and nano-scale surface characterization studies. The electrochemical techniques provide valuable information about the average electrochemical behavior of relatively large metal surfaces, typically in centimeter-square...

An experimental investigation of natural convection heat transfer from vertical flat plates in mercury

Creator:: White, Donald Henry
Abstract:: Heat transfer from a vertical flat plate in an infinite pool of mercury was investigated. Velocity profiles were measured with a hot-film anemometer and simultaneous temperature profiles measured with thermocouples in this low Prandtl number liquid metal. Constant heat flux plates at Grashof numbers of 9 x 10⁸ and 4...

Exploring the Distinct Solution Behavior of Isostructural Polycoltanates

Creator:: Fullmer, Lauren
Abstract:: Polyoxometalates are a rapidly growing class of discrete metal oxide clusters with a wide range of applications including functional materials. These anionic clusters of the group V and VI transition metals are inexpensive and non-toxic. Within group V polyoxometalates, niobium and tantalum chemistry has been underdeveloped owing to their unique...

Rogers, Perls, and Ellis in Three Approaches to Psychotherapy: A Corpus-based Study

Creator:: Miranda, Roberta A.
Abstract:: Counselor education programs traditionally have student counselors role-play therapy sessions to enhance skills in rapport building, aligning with a theoretical orientation, and other essential communication skills. Students, however, are often left to determine their own choice of words when engaging in these practice sessions, and consequently, experience uncertainty regarding how...

Absorption of methyl iodide by aqueous hydrazine solutions within spray chambers

Creator:: Postma, A. K.
Abstract:: Absorption of methyl iodide by aqueous hydrazine solutions within spray chambers was studied theoretically and experimentally. The objective of this work was to evaluate the absorption rate of airborne methyl iodide by sprays of hydrazine solutions under conditions expected to exist in post-accident nuclear reactor containment atmospheres. Experimental effort included...

LGBTQ+ coming out models : corpus based studies of academic and popular discourses

Creator:: Cisneros, Daniel
Abstract:: The process of coming out by an individual of the lesbian, gay, bisexual, transgender, and questioning (LGBTQ+) community involves recognition and disclosure, and it is a personal and important part of identity development. The process of coming out is also a symbol of the LGBTQ+ community’s self-disclosure of their sexual...
