From electrophoresis to dielectrophoresis: designing, fabricating, and evaluating an electroformed ratchet type microfluidic dielectrophoresis device

Creator:: Gonzalez, Carlos F.
Abstract:: Dielectrophoresis (DEP) is a separation method in which a non-uniform electric field is used to induce a dipole moment in a suspended particle. If the polarization of the particle is greater than that of the suspending medium, the particle will move towards the region of higher field strength (positive DEP);...

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,...

Single crystal growth, powder synthesis and characterization of layered chalcogenide semiconductors

Creator:: Richard, Annette Pauline
Abstract:: This thesis presents basic studies, including structural, optical and transport measurements, on novel chalcogenide powders and single crystals. BiCuOSe crystals have been synthesized for the first time. The crystal structure of BiCuOSe has been refined and the optical band gap has been measured to be 0.83eV. Crystal structure refinements of...

Chemical labeling methods and mass spectrometry of mitochondrial thiol proteomes

Creator:: Wang, Jing
Abstract:: Dysfunction of mitochondria has been linked to aging and the pathogenesis of many degenerative diseases. Aside from their primary function in energy production, mitochondria are considered as a major source and target of reactive oxygen and nitrogen species (ROS/RNS) in cells as well. The mitochondrial thiol proteome is a subset...

Deposition and characterization of transition metal oxides from aqueous solution

Creator:: Betterton, Sharon A.
Abstract:: The aqueous chemistries of two transition metal cations, Zr⁴⁺ and Nb⁵⁺, are examined and then used to develop inorganic precursor solutions. The oxides of these cations (ZrO₂ and Nb₂O₅) are deposited and characterized, and their morphological and optical properties discussed. Due to the obstacles created by niobium's aqueous chemistry, an...

Proteomic approach to the analysis of DNA-binding proteins using mass spectrometry

Creator:: Stapels, Martha Degen
Abstract:: In proteomic studies, separate experimental protocols have been necessary to identify proteins, determine their function, and predict their three-dimensional structure. In this study, a function-based separation of proteins was conceived to fractionate proteins prior to enzymatic digestion. In the initial demonstration of this technique, a DNA substrate was used to...

Determination of fluorinated alkyl substances in aqueous systems

Creator:: Schultz, Melissa M.
Abstract:: Fluorinated alkyl substances, which can be persistent, toxic, and bioaccumulative, have been quantitated in many densely populated and remote regions, including in air, surface waters, groundwater, and biota; however, little is known about their transport or behavior in the environment. Wastewater effluent is one of the principal routes for introducing...

Chemical and statistical analyses of chondrules from the Mokoia (CV3) meteorite

Creator:: Schilk, Alan J.
Abstract:: Nearly 100 chondrules were extracted from -8.6g of the Mokoia (CV3) meteorite and have been analyzed by sequential instrumental neutron activation analysis (INAA). The resulting data were utilized in a comprehensive statistical characterization of these objects and, unlike similar investigations, virtually no loss of relevant data was incurred due to...

A three-phase argon plasma arc for analytical emission spectroscopy

Creator:: Mattoon, Terence Richard
Abstract:: A new three-phase argon plasma arc was developed for analytical emission spectroscopy. The power supplied to the plasma arc utilized a simple circuit with three-phase as line voltage stepped down via a transformer to 104Vrms. A three concentric quartz tubing assembly was determined to be the optimum configuration for supplying...
