Nanostructured Optical Devices for Biosensing Applications

Creator:: Chalishazar, Vishvas
Abstract:: We demonstrated a sensitive biosensor based on plasmonic metal composite nanostructures. The device can be fabricated and duplicated with ease using a novel nanoprinting technology which allows precise transfer of metal nanostructures without complicated lithography processes. The design featured by its unique material composition and sub-wavelength structures maximizes the exposure...

Evaluation of the Performance of Lateral Spread Displacement Empirical Models for Subduction Zone Earthquake Case Histories

Creator:: Bunn, Michael
Abstract:: Lateral spread is a pervasive type of liquefaction-induced ground failure that occurs on gentle slopes or near free-faces, such as river channels. Resulting horizontal displacements can reach up to several meters, and can be considerably damaging to foundations, bridges, roadways, pipelines, etc. In the 1990s, Bartlett and Youd (1992a, 1995)...

Force Prediction in the Compression Sealing of an Ultra-thin Elastoviscoplastic Membrane

Creator:: McNeff, Patrick Scot
Abstract:: The objective of this paper is to demonstrate a method for mechanically characterizing a 25 μm thick elastoviscoplastic hemodialysis membrane and for quantifying the force required to use that membrane in compression sealing. First, methods are developed for mechanically characterizing the thin elastoviscoplastic membrane. Then, a finite element model is...

Density Functional Theory Investigation of CH Coupling and CH Hydrogenation Reactions on Different Cobalt Surface Facets and Fischer-Tropsch Temperature Swing Reactor Optimization

Creator:: Petersen, Dennis F.
Abstract:: Fischer-Tropsh Synthesis is a chemical process that converts CO and H₂ (syngas) into long stable hydrocarbon chains to use as fuel. This process suffers from large product distribution that requires expensive post processing. In this study, the reaction mechanism of hydrocarbon chain growth on Co is investigated on different surface...

Investigation of Optimal Extraction Conditions and Microencapsulation Technique for Stabilizing Anthocyanins and Polyphenols from Fruit Materials

Creator:: Wang, Wenjie
Abstract:: The objectives of this research were to investigate the optimal conditions for anthocyanins extraction from different anthocyanin rich fruit and to develop microencapsulation formulation for improving stability of anthocyanin extracts. In the extraction optimization study, two extraction methods, "conventional solvent extraction (CE)" and "ultrasound-assisted extraction (UE)" for three different anthocyanin-rich...

Investigation of Bioactive Compounds in Different Types of Fruit Pomace and Their Applications as Bulk Materials for Creating Biocomposite

Creator:: Gouw, Virginia P.
Abstract:: The objectives of this study were to evaluate the physicochemical properties and bioactive compounds from four different types of fruit pomace, including apple, blueberry, raspberry, and cranberry, and further to investigate the feasibility of creating apple pomace based biocomposite boards using thermal compression molding and to optimize the biocomposite formulations...

Active Learning and the ALEKS Placement Test in College Algebra : An Observational Study

Creator:: Dean, Raven
Abstract:: In 2012, a university in the north western United States began offering a redesigned college algebra class that had a greater emphasis on active learning. Specifically, two out of four class periods were completely devoted to students working together in small groups on carefully designed worksheets. Two years later, the...

Synthesis of Plasmonic-Enhanced Metal-Organic Framework Thin Films and their Infrared Sensing Application

Creator:: Ma, Guoheng
Abstract:: Transparent and electrically conductive metal oxide nanoparticles have attracted much attention, and can be used to improve the performance of solar cells, transparent electrode materials, and gas sensor technology. Specifically, indium tin oxide (ITO) nanocrystals (NCs) are potentially useful nanomaterials, having technological applications in enhanced sensitivity of optical spectroscopy due...

Assessing Student Conceptual Understanding : Supplementing Deductive Coding with Natural Language Processing Techniques

Creator:: Arbogast, Christian
Abstract:: Assessing student conceptual understanding is a valuable method for gauging specific student learning outcomes but can be difficult and time consuming to measure. This research investigates the potential of automating some intermediary steps of a qualitative analysis of student conceptual understanding with tools from the field of Natural Language Processing...

PAPR Reduction of Optical OFDM Systems with Exponential Companding Transform and Zero Padding

Creator:: Chen, Deyan
Abstract:: Optical wireless communication (OWC) is an alternative to radio frequency (RF)communication with a signi cantly larger and unregulated spectrum. In OWC systems, optical orthogonal frequency division multiplexing (O-OFDM) with intensity modulation and direct detection (IM/DD) is commonly used. There are two common signal structures in most OWC systems based on...
