Detecting Nanohertz Gravitational Waves by Searching for and Timing Millisecond Pulsars

Creator:: Nye, Brandon J.
Abstract:: Detecting gravitational waves is a topic at the forefront of physics. The first gravitational wave was detected by LIGO in 2015. This wave had a frequency in the 10s of Hz. This project is focused on detecting gravitational waves on the nanohertz spectrum using a pulsar timing array. This array...

Optical Modelling of Thin Films: Applying Effective Medium Theory to Mixtures of TiO₂ and SnO₂

Creator:: Wulf, Julian J.
Abstract:: This study used SCOUT optical modelling software to create models of the reflectance and transmittance spectra generated by mixtures of titanium dioxide (TiO2) and tin oxide (SnO2). These models enabled identification of how altering the ratio of a mixture changes the optical response. By being able to identify how altering...

The Gut Microbiome Drives Benzo[a]pyrene's Impact on Zebrafish Behavioral Development

Creator:: Sieler, Michael J.
Abstract:: Benzo[a]pyrene (B[a]P) is a common environmental pollutant produced from the incomplete combustion of organic matter, such as fossil fuel emissions. In vertebrates, B[a]P exposure is associated with hyperactivity, though the underlying mechanisms driving this effect are undescribed. Mounting evidence indicates that the gut microbiome, which is the diverse community of...

Ionic Strength and pH: A Look at Nanostar Stability

Creator:: Aldous, Tanner J. E.
Abstract:: Nanostars have many potential applications, particularly in biomedicine, such as drug delivery, detection assays, and even cancer treatment. Seeing how their plasmon changes in response to changes to the environment of the nanostars can give us an insight to the stability of the nanostars. Our current studies involve the effect...

Anti-Reflective Films: Spectroscopy and Ellipsometry of Porous Films

Creator:: Ramm, Joshua J.
Abstract:: The relationship between the index of refraction and the porosity of a material is that the index decreases with respect to the porosity. This property can be used to change the index of refraction of films which allows control of the reflection of the material. This is important because being...

Exploiting Diffraction Orders from a Phase Limited SLM to Remove and Model Zernike Aberrations

Creator:: Goschie, Aaron J.
Abstract:: Using a plastic bottle, we explore the capabilities of a reflective phase-only Spatial Light Modulator (SLM) in removing wavefront aberrations using a Zernike polynomial phase mask, with the modulators phase depth limited to 0.8π radians. Wavefront aberrations, which can be modeled with Zernike polynomials, distort image transmission through various optical...

Synchronized Cellular Mechanosensing due to External Periodic Driving

Creator:: Chase, Katelyn J.
Abstract:: The response of cells to periodic driving is important for many biological processes, particularly blood flow and heart functioning. Our research analyzes the collective shear stress response of fibroblast cells due to a periodic driving frequency. When cells experience shear stress, they release calcium into the cytosol. To quantify the...

Project BoxSand : Impact of Online Course Material and Mastering Physics Interactions on Exam Performance in a Flipped Classroom Environment

Creator:: Bigelow, Jake J.
Abstract:: A flipped classroom provides students with course content in the form of videos, readings, and/or simulations that they complete during the time traditionally used for homework assignments while in-class time is devoted to hands-on group learning activities. Project BoxSand is gathering quantitative data on how students in a flipped classroom,...

Meta-analysis of long-chain omega-3 polyunsaturated fatty acids and the risk of prostate cancer in prospective studies

Creator:: Chen, Sydnie J
Abstract:: Prostate cancer is the most common cancer among men in the United States. There are an estimated 115,024 incident cases so far in 2017. Risk factors for prostate cancer include age, black race, and family history of prostate cancer. In addition, healthful diet and lifestyle may affect risk of prostate...

Recycling Potential of Sequential Hydrothermal Liquefaction Aqueous Co-Product Using Chlorella vulgaris

Creator:: Wallach, William J.
Abstract:: Bio-oil from hydrothermal liquefaction (HTL) represents a promising fuel source due to large higher heating values and compatibility with current energy infrastructure. For bio-oil production to become commercially viable, novel methods of co-product recycling must be explored. The aims of this study were to culture Chlorella vulgaris, a common HTL...
