Three-Way Catalysts In Passive Selective Catalytic Reduction Systems, Calvin Thomas
Theses and Dissertations
Conventional gasoline-powered engines operate with a stoichiometric air-fuel ratio (AFR), but greater fuel economy is achieved in lean burn engines by increasing the AFR. The primary drawback to these engines is the nitrogen oxide (NOX) emissions, which cannot be reduced over a conventional three-way catalyst (TWC). Passive selective catalytic reduction (SCR) is a promising approach for the control of NOX emissions in lean burn systems. By periodically decreasing the AFR to fuel-rich levels, ammonia (NH3) can be produced over a TWC and stored on a downstream SCR catalyst for the reduction of NOX during normal lean operation. While passive SCR …

A Nonlinear Systems Framework For Cyberattack Prevention For Chemical Process Control Systems, Helen Durand
Chemical Engineering and Materials Science Faculty Research Publications
Recent cyberattacks against industrial control systems highlight the criticality of preventing future attacks from disrupting plants economically or, more critically, from impacting plant safety. This work develops a nonlinear systems framework for understanding cyberattack-resilience of process and control designs and indicates through an analysis of three control designs how control laws can be inspected for this property. A chemical process example illustrates that control approaches intended for cyberattack prevention which seem intuitive are not cyberattack-resilient unless they meet the requirements of a nonlinear systems description of this property.

Measuring Up: Engineering Stronger And Faster Cardiomyocytes, Kaitlyn Mcentire, Dr. Alonzo Cook
Journal of Undergraduate Research
If a heartbeat connotes life, then cardiomyocytes are the life givers. When heart disease results in cardiomyocyte death, however, these life-giving, beating cells are unable to reproduce, and portions of the heart irreversibly die. Despite modern technology and developments in heart disease treatment and prevention, heart disease remains the number one cause of death in America. With an inability to meet an ever-increasing demand for heart transplants, any potential alternative must be pursued.

Equilibration Of Chloride Ions In Concrete Bridge Decks After Rehabilitation Using Hydro-Demolition And Concrete Overlay, Elizabeth Newbill, Dr. Spencer Guthrie
Journal of Undergraduate Research
In cold regions like northern Utah, harsh winters can lead to decreases in the service life of concrete bridge decks. Chloride-based deicing salts, which are commonly used to remove snow and ice from the surface of concrete bridge decks during winter months, are of particular concern. Even in uncracked concrete, chloride ions can diffuse into the bridge deck and eventually lead to corrosion of the embedded reinforcing steel. When chlorides corrode the steel, expansive rust forms, which causes cracks to form in the deck. These cracks allow for greater chloride ingress, accelerating the corrosion and deterioration processes within the bridge …

LSU Doctoral Dissertations
Unsustainable exploitation of fossil fuel and its massive greenhouse gas emission necessitates the development in alternative energy sources. Chemical fuels (CH3OH or C2H5OH) outperform other choices, such as batteries for their high energy densities, which is key to portability. Electrochemical reduction of CO2is capable of producing a wide range of valuable fuels (Syngas, formic acid, methane and methanol, etc.). Converting CO2into carbon-based fuels further closes the carbon neutral cycle, which contributes to the effort in reducing global CO2emission. Integration of organic ligands with transition metals shows great potential …

The purpose of this project is to address the unmet need for a comprehensive, multiscale, regime- and fuel-independent turbulent reacting model by using a novel, physics-based strategy called Hierarchal Parcel Swapping (HiPS). Turbulent flow has been called the most important unsolved problem of classical physics. Modeling turbulent flow is extremely important due to the fact that nearly all flows in the real world are turbulent. Though the exact details of turbulent flow are not of great importance to an engineer, the effect turbulence has on chemical reactions and the overall chemical properties is vital. The solution to the turbulence problem …
