Identification Of Fungi And Their Secondary Metabolites From Wind Cave [Poster], Kyle J. Biscoglia, Kirk Manfredi Ph.D.

Summer Undergraduate Research Program (SURP) Symposium

Eighteen fungal samples were isolated from samples of water collected in Wind Cave, South Dakota. Ten of the samples underwent chemical extraction, a growth inhibition test, and were analyzed using proton nuclear magnetic resonance spectroscopy and liquid chromatography-mass spectroscopy. All eighteen of the fungal samples were able to be identified to the genus level using the ITS region of their DNA, however confident identification of the species level was more difficult to attain just looking at one portion of the sequence.

Analog Studies Of Organic Pathways In Wind Cave Through Cave Water And Crystals, Wilson Mcnaughton, Joshua Sebree Ph.D.

Summer Undergraduate Research Program (SURP) Symposium

In Wind Cave, organic molecules from the surface dissolved in water will slowly filter down into the cave through the porous limestone. While the water slowly proceeds down through the limestone, the water dissolves the limestone along the way. This dissolving of the limestone causes a quasi-equilibrium that deposits the organic molecules into the calcite structures found in Wind Cave. These large trapped organic molecules, mainly humic and fulvic acid, can be tracked by using UV light. The UV light causes these molecules to fluoresce blue, while the calcite structures generally do not have a strong blue fluorescence. The water …

Comparison Of Chalk Types And Their Ghosting Effects, Felicienne Alexandre, Shoshanna Coon, Kirk Manfredi

Summer Undergraduate Research Program (SURP) Symposium

Chalkboard ghosting is a faint image on a chalkboard's surface after writing is erased. Many types of chalk leave a positive image, while the Crayola An-du-septic Anti-dust chalk leaves a negative image. To better understand what cause the ghosting effects, two different types of Crayola chalk (regular and anti-dust) were investigated. Raman spectroscopy and infrared (IR) spectroscopy were used to determine the majority material the chalk was made of, by comparison with pure substances. To identify the organic compound binders holding the chalk sticks together, pulverized chalk was immersed in 40 mL of toluene for at least 30 minutes. After …

Sustainable And Biodegradable Nanocellulose Composite Materials, Jacob Scheel, Tim Kidd Ph.D.

Summer Undergraduate Research Program (SURP) Symposium

Nanocellulose is made from a mixture of cellulose powder, and a variety of different materials and liquids. Unfortunately the cost to produce nanocellulose isn’t ideal, thanks to shrinkage. The goal of my research this year was to try to make nanocellulose more cost effective, by reduce shrinkage.

Chemical Substitution Induced Half-Metallicity In Crmnsb0.5si0.5, Lukas Stuelke, Pavel Lukashev Ph.D.

Summer Undergraduate Research Program (SURP) Symposium

Background

⮚Research on magnetic materials for potential applications in spin-based electronics: one of the most active fields in academia and industry. ⮚High degree of spin polarization – wanted in spintronics. ⮚Spintronics – an emerging technology utilizing a spin degree of freedom. ⮚Various mechanisms alter degree of spin polarization – mechanical strain, structural disorder, temperature, termination surface/interface, etc. ⮚Magnetic materials that conduct electrons of only one spin are called half-metals, and have a great potential in spintronics.

Virtual Vs. In-Person Instruction: The Impact Of Teachers' Understanding Of Physics, Madelyn Johnson, Jeff Morgan Ph.D., Lawrence Escalada Ph.D.

Summer Undergraduate Research Program (SURP) Symposium

Covid-19 forced nearly all U.S. schools to switch to virtual instruction in March of 2020. With students around the country and world now “Zooming” into class, it begs the question, does this new learning environment impact student learning? Conceptual assessments and observations were used to make conclusions about the differing effectiveness of instructional methods for professional development programs. Although results may indicate in-person instruction is more effective, I believe the most effective method of instruction is hybrid as it takes advantage of both virtual and in-person methods.

Designing Promise Programs: Decisions And Effects, Shay Slifka

Major Themes in Economics

Having gained popularity over the past two decades, promise programs are a relatively new policy tool aimed at increasing the number of people who earn two-year and four-year postsecondary educational degrees by providing partial or full financial aid. In contrast to other forms of financial aid for postsecondary education, promise programs guarantee funding to students of a specified geographic area, which is sometimes accompanied by merit or need-based requirements. Promise programs differ in design, vary in result, and potentially cause substitution and migration effects. By analyzing several mature promise programs, I identify three fundamental design decisions that policymakers must consider …

Poster Session: Predicted Net Flux Versus Pressure Profiles During A Probe Descent Into Uranus’S Atmosphere, Meredith Wieber, Shahid Aslam, Maarten Roos, Patrick Irwin, Geronimo Villanueva

Society of Physics Students Regional Meeting

The responsivity of the proposed Net Flux Radiometer (NFR) for the Ice Giants was examined, using a specialty browser tool. This tool takes simulated spectra of Uranus, along with specific parameters of the NFR, and applies Net Flux calculations in order to produce a net flux profile, a simulated view of what the NFR probe would observe as it plunged into Uranus’s atmosphere. The efforts of this project led to a redesign of the NFR to include an increase in the FOV of the radiation-collection windows from 5° to 10°, as well as the selection of spectral bandwidths for observation …

Poster Session: Tagging Pb-214 Decay Events Via Toy Monte Carlo Method, Samuel Schleich

Society of Physics Students Regional Meeting

Pb-214 β-decay events within a liquid xenon time projection chamber can often look identical to the signature of a WIMP interaction, which causes false positives in the search for dark matter. To combat this, we can “tag” decay events of the Rn-222 decay chain, which is based on the timing and position of decay events. My algorithm pieced these events together like puzzle pieces to determine the validity of Pb-214 β-decay events. Using a Toy Monte Carlo model, I was able to simulate both the Rn-222 decay chain and begin to tag decay events to eliminate false positives.

Poster Session: Simulating Griffiths Phase Behavior, Aaron Janaszak

Society of Physics Students Regional Meeting

The Griffiths Phase is a result of a spontaneous increase in the overall magnetization of the system primarily influenced by the rare, large clusters transitioning to a ferromagnetic state at the Curie temperature. Approaching this computationally, we were able to create a MATLAB program that exhibits this trend by using the Langevin function to simulate clusters. Modifying variables resulted in behaviors similar to that experienced in a laboratory setting, lending support to the veracity of the model. Further refinement of the computational model could allow in-depth exploration and lead to a better understanding of the Griffiths Phase.
