Stripe Order, Impurities, And Symmetry Breaking In A 3-Dimensional Model Of A Diluted Frustrated Magnet, James Elverson, Thomas Vojta Apr 2024

Stripe Order, Impurities, And Symmetry Breaking In A 3-Dimensional Model Of A Diluted Frustrated Magnet, James Elverson, Thomas Vojta

Undergraduate Research Conference at Missouri S&T

Many quantum materials feature low-temperature phases that break realspace symmetries in addition to spin or charge symmetries. Examples include stripe phases in cuprate superconductors, nematic phases in iron pnictides, and spin-density waves in magnetic materials. Realistic materials always contain some quenched disorder or randomness. To understand the effect of disorder on phases that break real-space symmetries, we investigate the influence of spinless impurities on a frustrated 3-dimensional J 1-J2 Ising model through Monte Carlo simulations. Spin less impurities generate random field type disorder for the spin-density wave (stripe) phase in this system. Whereas the long-range stripe order is destroyed by …

Density Fluctuations Measurements In Supersonic Flows, Allie Dingfield, Davide Vigano

Undergraduate Research Conference at Missouri S&T

Turbulence in compressible flows plays a major role in a variety of aerospace applications. However, due to fluctuating thermodynamic quantities, compressible turbulence is challenging to analyze. Of these quantities, density fluctuations are of high importance due to their role in describing turbulence. A method to obtain quantitative measurements of density fluctuations has been developed using the optical technique of shadowgraph imaging. Shadowgraph imaging has frequently been used to obtain qualitative information about density gradients in fluids. However, quantitative application of these methods is much less common. The quantitative shadowgraph method presented here relates the light intensity variations in an image …

Turbulence Characterization For Supersonic Wind Tunnel, Allie Dingfield

Undergraduate Research Conference at Missouri S&T

Turbulence in compressible flows holds significant importance across various applications, such as optimizing air/fuel mixing in scramjet combustors. However, managing compressible turbulence presents distinct challenges compared to incompressible flows, as fluctuations extend to thermodynamic quantities, including density. Density fluctuations notably influence the production term of Turbulent Kinetic Energy (TKE). Despite advancements in velocity measurements, particularly in supersonic flows, density measurement remains inherently complex. This study focuses on further refining a turbulence density measurement technique utilizing shadowgraph imaging, tailored for application in the recently upgraded Missouri S& T supersonic wind tunnel.

Floating Treatment Wetlands For Zinc Phytoremediation, Grace Duong Apr 2024

Floating Treatment Wetlands For Zinc Phytoremediation, Grace Duong

Undergraduate Research Conference at Missouri S&T

Stormwater pollution from urban and mining areas can pose challenges to downstream waters because of zinc contamination. Floating treatment wetlands (FTWs) have demonstrated the ability to mitigate nutrient and metal contamination. To investigate the effectiveness of native Missouri plants in FTWs, fourteen 10-liter mesocosms were constructed, dosed with nutrients, and placed in a greenhouse. Four mesocosms acted as controls, five contained pickerelweed, and five contained palm sedge. After one week of acclimation, mesocosms were dosed with ZnCl2 in concentrations of 0, 5, and 10 mg/L of zinc. Objectives of this study include characterizing zinc immobilization and assessing both pickerelweed and …

Next Generation Alloy Development For Scanning Induction Hardened Bearings, Ashton Ventura, Mario F. Buchely

Undergraduate Research Conference at Missouri S&T

To increase the hardenability of Timken 4150 steel, the material was alloyed with either vanadium; vanadium and silicon; or received no alloying. The material underwent hot rolling and induction heating to simulate Timken's forming and heat treatment processes for their windmill bearings. Hardness, and toughness were tested and compared between the three materials. Both alloyed metals reported better hardness and toughness compared to the original steel with the vanadium-silicon steel recording the highest for both properties.

Undergraduate Research Conference at Missouri S&T

Topological materials can serve as promising platforms for next-generation technology. Magnetism in such systems is often a consequence of emergent quantum phenomena, and the traditional framework is insufficient to fully describe their magnetic properties. In this project, we will perform precision magnetic measurements utilizing the Colpitts self-oscillator to determine the temperature- and field-dependent AC magnetic susceptibility in the topological magnetic materials. The collective knowledge learned from this proposed research would shed light on the understanding of exotic magnetism in topological materials, potentially leading to new physics of magnetism.

Cytokinesis And Dbf2, Katharine Gray, Katie Shannon Apr 2024

Cytokinesis And Dbf2, Katharine Gray, Katie Shannon

Undergraduate Research Conference at Missouri S&T

During cell division, the cytoplasm must be divided between the parent and daughter cell. The Mitotic Exit Network (MEN) is a signaling pathway that allows a dividing cell to exit mitosis and complete cytokinesis. Obf2 is a MEN protein kinase in yeast, which provides a simplified model for studying this conserved pathway. By regulating Dbf2s' activity through phosphorylation mutants, its effect on cytokinesis can be studied. Cells were viewed under a microscope, to visualize division errors. Yeast cells that fail to complete cytokinesis will form chains, as the budding daughter cells fail to separate from their parents. Chains of 3 …

Laser Ablation Pulsing On A Cp-Ftmw, Harrison Hawxby

Undergraduate Research Conference at Missouri S&T

The goal of this research is to study metal containing molecules in the gas phase for structural determination. In order to do this, a metal rod that is turning on a 12V motor is struck by a Nd:YAG laser. Rotational spectra were recorded on a chirped-pulse Fourier transform microwave spectrometer (CP-FTMW) with laser ablation sourcing.

Xenobiotic-Lnduced Developmental Neuropathology, Lindsay Schneider Apr 2024

Xenobiotic-Lnduced Developmental Neuropathology, Lindsay Schneider

Undergraduate Research Conference at Missouri S&T

As new drugs and pollutants are introduced, a larger subset of people are exposed. The question that arises is whether exposure of a pregnant woman to drugs/pollutants will have negative effects on the neurobiology of her unborn child. We are establishing a screen to test the effects of drugs and pollutants on the developmental neuropathology of the model organism, Caenorhabditis elegans. The roundworm has 302 neurons that are structurally similar to human neurons, and defects in single neurons can be detected by impairment in their neural behaviors such as chemotaxis towards an attractant. Using a chemotaxis assay, we can investigate …

Stream Fungal Biodiversity And Leaf Decomposition, Vale Miller Apr 2024

Stream Fungal Biodiversity And Leaf Decomposition, Vale Miller

Undergraduate Research Conference at Missouri S&T

CURRENTLY ONGOING PROJECT We are investigating the possible impact of aquatic fungi biodiversity on leaf litter decomposition and respiration. Four different species of aquatic fungi were placed into flasks with leaf cores (A, B, C, and D), one with no fungi as a control, and one with all four species in equal amounts (ABCD). So far, there seems to be little to no effect on respiration between the species and similar results in the flasks with all four species. Based on this information, biodiversity has yet to show a significant impact in leaf respiration and little to no effect on …
