Beyond: Undergraduate Research Journal
The Temperature Sensitive Paint (TSP) is a widely used method in measuring and visualizing flow separation and heat transfer. Compared to the cost and time consumption needed for methods such as pitot tubes, temperature sensitive paint is a cheaper alternative. Due to high usage in College of Engineering research projects, it was determined that in house fabrication of temperature sensitive paint would reduce time and cost limitations. For initial stages, literature research was performed to determine the recipe of intensity based TSP with luminophore and polymer binder that operated optimum at temperatures from 0-100°C. Europium III thenoyltrifluoroacetonate was determined to …

The effect of differential molecular diffusion (DMD) in turbulent non-premixed flames is studied by examining two previously reported DNS of temporally evolving planar jet flames, one with CO/H2 as the fuel and the other with C2H4 as the fuel. The effect of DMD in the CO/H2 DNS flames in which H2 is part of fuel is found to behave similar to laminar flamelet, while in the C2H4 DNS flames in which H2 is not present in the fuel it is similar to laminar flamelet in early stages but becomes different from laminar flamelet later. The scaling of the effect …

1,4-dioxane is an emerging contaminant that was used as a corrosion inhibitor with chlorinated solvents. Metal-activated persulfate can degrade dioxane but reaction kinetics have typically been characterized by a rapid decrease during the first 30 min followed by either a slower decrease or no further change (i.e., plateau). Our objective was to identify the factors responsible for this plateau and then determine if slow-release formulations of sodium persulfate and Fe0 could provide a more sustainable degradation treatment. We accomplished this by conducting batch experiments where Fe0-activated persulfate was used to treat dioxane. Treatment variables included the timing …

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 and the dangers of immunosuppressant drugs, any potential alternative to cardiac transplantation must be pursued. The end goal of this research is to engineer biocompatible tissues that are fully functional to repair or replace damaged portions of the heart following the loss of cardiac function. This research investigates the effect of porcine extracellular matrix as the scaffold for beating IPS-differentiated cardiomyocytes.

Molecular Modeling Of Antibody-Antigen Binding Near Solid Surfaces, Derek Bush, Thomas Knotts
Biomedical Engineering Western Regional Conference
Antibody microarrays are biosensors that have the potential to revolutionize molecular detection in medicine, scientific research, and national defense. However, current microarrays are not widely used due to problems including poor reproducibility and signal quality, unbalanced antibody performance, and cross-reactivity. Prior work in the area focused mainly on the stability of the antibody alone and not its affinity for its antigen. This presentation shows results of using molecular simulation to determine how different types of surfaces affect antigen binding to surface-tethered antibodies. The results offer an unprecedented, molecular-level view into these protein-protein-surface interactions and how to drive binding to occur.

The electrochemical behavior of MgCl2 in molten LiCl-KCl eutectic was investigated to evaluate its suitability as a surrogate for PuCl3 in studies related to the eletrorefining of used nuclear fuel. The reduction of Mg2+ was found to be electrochemically reversible up to 300 mV s−1 at 773 K. The diffusion coefficient for Mg2+ was calculated to be 1.74 and 2.17 × 10−5 cm2 s−1 with and without U3+ present, respectively, at 773 K using cyclic voltammetry (CV). Upon comparison to literature data, the diffusion coefficient of Mg2+ differs by only 8.8% (with U …

Novel Experimental Method For The Determination Of The Minimum Agitation Speed For Solids Suspension In Flat-Bottomed Stirred Tank Reactors, Shriarjun Shastry
Theses
Knowledge of the minimum agitation speed, Njs, required to suspend finely divided solids in vessels stirred by an impeller is a critical parameter to properly operate industrial tanks in a large number of industrial operations. The most common experimental approach to measure Njs is that of Zwietering’s (Chem. Eng. Sci., 1958, 8, 244-253), consisting of visually inspecting the tank bottom and visually determining the impeller agitation speed at which the solids are observed to rest on the tank bottom for no more than 1-2 seconds before being swept away. This method is quite reliable, but a method …

Temperature measurement and manipulation is a critical factor in a wide range of applications like Point Of Care Diagnostics (POC's), Polymerase Chain Reaction (PCR), Temperature Gradient Focusing (TGF) to cite few prominent examples. In the past decade, researchers have used various techniques to sense and control the temperature in microfluidic systems. The primary challenge has been the twin problem of integration and accuracy using minimal equipment while keeping it simple. In this study, an equipment free fabrication of the temperature sensor using filter paper impregnated with p-type colloidal PbS quantum dots is demonstrated. This sensor is later integrated into line …

An electric field is used to construct pillars on films of bisphenol-A-polycarbonate (BPAPC) between two parallel electrodes. Both the size and density of the pillars are dependent on the film thickness. For the same experimental conditions, thicker films will lead to the formation of pillars of larger sizes and smaller densities. The time dependence of the average diameter of the pillars is found to be a linear function of the square root of the difference between the annealing time and incubation time. The temperature dependence of the temporal evolution of the pillars follows the Arrhenius relation with an activation enthalpy …

While it is true that fossil fuel based energy which is non-renewable has contributed immensely to global economic growth, it has brought with its usage the emission of carbon dioxide (CO2), a principal greenhouse gas. Studies using business as usual (BAU) model has predicted that the emission of CO2 into the atmosphere will increase by 50 to 250% by the year 2050 with perhaps a commensurate increase in the global carbon footprint. The shipping industry has remained a major contributor to this global carbonization. Concern over this increasing concentration of carbon dioxide in the atmosphere, has intensified interests in developing …

Engineering A Fluorescent Protease Sensor For In Vivo Protein Detection, Thomas C. Kinard
Honors Scholar Theses
This report details the results of an ongoing project to engineer a mutant form of Red Fluorescent Protein (RFP) variant mCherry that acts as a real-time in vivo protease sensor. The sought-after mutant only becomes fluorescent when exposed to Tobacco Etch Virus (TEV) Protease, this system’s model protease. This will be accomplished via the insertion of the TEV Protease Recognition Site (TEV-PRS) in such a position that, before cleavage, will prevent the protein from folding to fluorescent conformation, but upon cleavage, will allow for fluorescent conformation to occur. The cylindrical structure of the protein, composed of beta-pleated sheets, contains “loops” …

The fatigue properties and the damage mechanism of a Cr-Mn austenite steel were investigated using four-point bend fatigue testing. The stress-number of cycles to failure (S-N) curve of the Cr-Mn austenite steel was measured at room temperature, at the frequency of f=20 Hz and the stress ratio of R=0.1. The fatigue strength of this Cr-Mn austenite steel was measured to be 503 MPa in the maximum stress. Multiple cracks are initiated on the sample surface after fatigue failure tests, and usually only one or two of them can lead to the final failure of the samples. Most of the cracks …
