On Electric Conduction Of Amorphous Silicon Carbonitride Derived From A Polymeric Precursor, Yaohan Chen, Fuqian Yang, Linan An

Chemical and Materials Engineering Faculty Publications

A long-existing problem that the conductivity of amorphous silicon carbonitrides derived from polymeric precursor increases significantly with pyrolysis temperature is investigated. We show that the conductivity exhibited an Arrhenius dependence on pyrolysis temperature, with the activation energy of ∼3.41 eV. Structural analysis using Raman spectroscopy reveals that the free carbon within the material undergoes a sp³-to-sp² transition as pyrolysis temperature increases, with the activation energy of ∼3.6 eV. We conclude that the pyrolysis-temperature induced increase in the conductivity is mainly due to the increase in the conductivity of the free carbon. A simple model is proposed to …

Poly(N-Isopropylacrylamide)-Based Scaffolds For Tissue Engineering Applications, Pamela Kubinski

Theses and Dissertations

The primary goal of this work is to investigate the potential of poly(Nisopropylacrylamide)- based scaffolds in tissue engineering applications, specifically spinal injury and nucleus pulposus replacement. Poly(N-isopropylacrylamide), denoted PNIPAAm, is a synthetic polymer with hydrophilic properties at room temperature, but above 32C the chains become hydrophobic and entangle to form physical crosslinks. This thermoresponsive property enables PNIPAAm to be implanted as a free-flowing solution at room temperature and collapse into a gel in physiological conditions. However, as a homopolymer, the hydrophobicity of PNIPAAm in vivo causes the hydrogel to expel water and exhibit inelastic properties that do not mimic those …

Ramjet Combustion Chamber, Paul Cameron Stone

Aerospace Engineering

A ramjet combustion chamber is designed and some initial assembly fabrication and test completed as a component of a ramjet graduate project for California Polytechnic State University, San Luis Obispo Supersonic Wind Tunnel. The combustor design is driven by a theoretical model created by a Cal Poly graduate student, Harrison Sykes. Temperature, pressure, and fuel flow will be measured.

Development Of A High Precision Quantum Dot Synthysis Method Utilizing A Microfluidic Reactor And In-Line Fluorescence Cell, Harry Lafferty, Jonny Hoadley

Materials Engineering

Quantum dots show great potential for use as spectral converters in solar cells, lighting applications and biological imaging. These applications require precise control of quantum dot size to maximize performance. The fluorescence profile of quantum dots in solution correlates directly with particle size. An alternative, high precision process was developed for the synthesis of cadmium-selenide quantum dots using a microfluidic reactor and fluorescence flow through cell. The process required creating separate cadmium and selenium precursors that were then mixed in a nitrogen environment at 17± 1°C. Using an NE-300^® syringe pump, the solution was pumped through a microfluidic reactor …

Advanced Deepwater Monitoring System, David Brower, John Hedengren, Reza Asgharzadeh Shishavan, Alexis Brower

Faculty Publications

This study investigates new methods to improve deepwater monitoring and addresses installation of advanced sensors on ”already deployed” risers, flowlines, trees, and other deepwater devices. A major shortcoming of post installed monitoring systems in subsea is poor coupling between the sensor and structure. This study provided methods to overcome this problem. Both field testing in subsea environments and laboratory testing were performed. Test articles included actual flowline pipe and steel catenary risers up to twenty-four inches in diameter. A monitoring device resulting from this study can be installed in-situ on underwater structures and could enhance productivity and improve safety of …

Utilization Of Wet Corn Distillers Grain For The Production Of Cellulase Enzymes And Value Added Products, Hunter R. Flodman

Department of Chemical and Biomolecular Engineering: Dissertations, Theses, and Student Research

Distillers grain, a byproduct from the dry grind corn ethanol industry, is an industrially available, abundant, preprocessed material comprised primarily of cellulose, hemicellulose, protein, oil, and minerals. This research investigated the utilization of distillers grain as a substrate for solid-state fermentation (SSF). SSF is the growth of microorganisms on a moist, solid substrate in the absence of free water. The substrate acts as both the nutrient source and as a solid support for the microorganisms, typically filamentous fungi. SSF has the unique ability to convert agricultural byproducts into valuable bioproducts such as enzymes and organic acids without hydrolyzing polysaccharides to …
