Effect Of Short-Chain Polymer Binders On The Mechanical And Electrochemical Performance Of Silicon Anodes, Fei Sun, L. Zurita-Garcia, Dean R. Wheeler
Effect Of Short-Chain Polymer Binders On The Mechanical And Electrochemical Performance Of Silicon Anodes, Fei Sun, L. Zurita-Garcia, Dean R. Wheeler
Faculty Publications
Polymer binders are crucial components in providing both mechanical support and chemical stability to the structure of porous Li-ion electrodes. Particularly in silicon anodes, the active material undergoes substantial volume expansion of up to 275%. Due to the mechanical constraint of the current collector, these silicon materials tend to expand in the normal direction while exhibiting substantial particle rearrangement and plastic deformation. Conventional rigid binders such as polyacrylic acid (PAA) and polyimide (PI), while providing satisfactory initial capacity, do not eliminate diminished long-term performance. Our research attempts to develop binder formulations that can accommodate sufficient flexibility for the substantial volume …

Comparative Civilizations Review
For many years, I have been an active member of the International Society for the Comparative Study of Civilizations and Editor-in-Chief of its journal, the Comparative Civilizations Review. Since the 1960s, I have also been a university administrator and a professor, globe-trotting to learn about societies near and far, their rises and falls. Yet even though I lived and worked in Prague, as president of a university, not far from the Polish border, I had never set foot in that country, notwithstanding that my paternal grandfather came from there.

Although religiosity is commonly linked to marital satisfaction in sociological research, few studies have examined how it strengthens marital commitment among women of faith. This study explored the perspectives of religious, heterosexual married women using interviews in the United States from 196 highly religious couples with successful marriages. Three core themes emerged: (1) personal commitment—including the decision to marry, religious beliefs and practices, and the need for effort and sacrifice; (2) moral commitment—highlighting sexual relations before marriage, promises made before God, family, and friends, and views on fidelity and divorce; and (3) structural commitment— emphasizing the role of a religious …

Robert Wesley McMullin (April 29, 1921 – January 3, 1995) was a Canadian composer, conductor, instrumentalist and music director. While he was born into a Mormon family in Utah, he was a proud Canadian: in a 1965 interview with Canadian Composer, he said: “The brain drain to the United States is a bad thing. It reduces our chances of arriving at a distinctive Canadian art form.” He composed works for orchestra, band, and piano, but the bulk of his compositions were for radio or television programming. Later in his career, he scored several films.

To develop affordable tabletop neutron sources for neutron science research and education, GS20 scintillator glass doped with Americium-241 is being evaluated inside the BYU Isotropic Fission Chamber (IFC). Our 1985 sample was assessed for radiation damage and found to be in good condition. Neutrons from Am-241 interactions were optically flagged and observed using the IFC in conjunction with the LGB-PVT Neutron Pseudo Spectrometer Detector. Data was recorded via a CAEN desktop digitizer. The analysis code continues to be developed, and the neutron detector will be calibrated using deuterium-deuterium (DD) interactions in the future.

Engineering Protein Linkers For Optimized Telsam-Darpin Fusion And Crystallization With Electric Field-Based Polymer Orientation, Maria Jose Pedroza Romo
Theses and Dissertations
Fusing a variant of the sterile alpha motif domain of the human translocation ETS leukemia protein (TELSAM) to a protein of interest significantly enhances crystallization and diffraction quality. TELSAM is a pH-dependent, polymer-forming crystallization chaperone that, when covalently fused to a protein, forms a well-ordered crystal lattice. However, the success of this method depends on two factors: 1) the design of the linker connecting TELSAM to the target protein, which influences both crystal packing and target orientation, and 2) the prevention of TELSAM polymer flipping, a phenomenon that disrupts lattice periodicity and impairs structure determination. To address the first challenge, …
Cost-Effectiveness Model For Reservoir Sediment Management Economics, Connor Ronald Hale
Cost-Effectiveness Model For Reservoir Sediment Management Economics, Connor Ronald Hale
Theses and Dissertations
Reservoir sediment deposition poses a challenge to sustainable water supplies around the world. Sediment management has proven to be an expensive endeavor. Two models have been developed to guide economic analysis for reservoir sediment management, namely the Reservoir Sediment Economics Model (RSEM) and the Reservoir Conservation Model 2 (RESCON 2). While these are helpful tools for benefit-cost prefeasibility studies, they rely heavily on sometimes elusive estimations of the benefits of water supply. In this study, a new method for economic analysis is proposed that foregoes benefit-cost analysis in favor of a cost-effectiveness approach. The Sediment Management Cost-Effectiveness Model ranks sediment …

Magnetic Ordering And Dynamics In Assemblies Of Magnetite Nanoparticles Throughout The Superparamagnetic Transition, Johnathon Michael Rackham
Magnetic Ordering And Dynamics In Assemblies Of Magnetite Nanoparticles Throughout The Superparamagnetic Transition, Johnathon Michael Rackham
Theses and Dissertations
Magnetic nanoparticles are used in nanotechnologies and biomedical applications, such as drug targeting, hyperthermia treatment, MRI contrasting agents, and bio-separation of compound solutions. Magnetite (Fe3O4) nanoparticles stand to be effective in these roles due to the non-toxic nature of magnetite and its strong magnetization. To this end, a greater understanding of the magnetic behavior of the individual magnetite nanoparticles is needed when a collection of them is used. This research seeks to discover the local magnetic ordering and dynamics of fluctuations of ensembles of magnetite nanoparticles at various stages of the magnetization process, throughout the superparamagnetic blocking transitions, and for …
Seating Charts, Connections, And Fostering Community, Mckenna B. Chow
Seating Charts, Connections, And Fostering Community, Mckenna B. Chow
Theses and Dissertations
This thesis explores how fostering stronger connections in the high school ceramics classroom can create a more inclusive and collaborative community. I regularly changed seating charts to encourage new relationships and strengthen classroom culture as part of this effort. Historically, seating charts have enforced uniformity and promoted specific behaviors. My research challenges these traditional purposes and proposes that seating arrangements can instead serve a more meaningful and enduring goal: promoting connection and ensuring that all students feel seen. I found that while seating charts can contribute to this goal, achieving genuine connection and inclusivity also requires several additional factors to …

Evaluating Nfl Quarterback Decision Making Through Tracking Data, Jesse N. Melville
Theses and Dissertations
Quarterback decision-making is one of the most critical determinants of success in the National Football League (NFL), yet traditional statistics fail to account for the spatial, temporal, and contextual factors influencing each play. This thesis proposes a data-driven methodology for evaluating quarterback decisions using NFL player tracking data from the 2022 season. We replicate and extend the DeepQB framework by training deep learning models to estimate expected completion probabilities and expected yards gained for each receiver at the moment of the throw. Our extension applies the approach to a newer dataset with additional contextual features, enabling a more detailed evaluation …

Few studies address how relational factors may be interdependent and impact child-focused problems that could be collectively addressed in systemic family therapy. The current study utilized a cross-lagged panel model to explore the associations of parental anxiety, familial dysfunction, and child emotion regulation between four family therapy sessions. The study included 224 parents who sought family therapy and participated in the Marriage and Family Therapy Practice Research Network (MFT-PRN). Data were collected at two time points across four family therapy sessions. The findings indicated that higher levels of parental anxiety at intake were associated with higher familial dysfunction at session …
A Dendrite Equivalence Relation On Loop Spaces, Spencer Arnesen
A Dendrite Equivalence Relation On Loop Spaces, Spencer Arnesen
Theses and Dissertations
In Definition 2.0.3 we define an equivalence relation on paths such that two paths into a space X are related if doing the first, then the second backwards factors as a loop through a dendrite. This equivalence relation induces a group structure L(X) on a large subset of the loop space of X, namely all loops that have a unique reduced representative. We show that certain continuous maps induce a homomorphism between dentropy groups and that projection from three-dimensional real space to two-dimensional real space does not induce a homomorphism on dentropy groups.. We show that dentropy groups are locally …

Superconducting radiofrequency (SRF) cavities are essential components in modern particle accelerators, enabling the efficient acceleration of charged particles for various applications in physics, medicine, materials science, and beyond. The performance of these cavities is significantly influenced by the properties of superconducting materials, such as niobium (Nb) and triniobium-tin (Nb3Sn), and the defects and surface features present within the material. This dissertation presents a computational study focused on understanding the behavior of SRF cavities, using a sample-specific time-dependent Ginzburg-Landau (TDGL) framework to simulate their performance under realistic material conditions. The research integrates experimental data and density functional theory (DFT) calculations to …
Mathematics Student Teachers' Curricular Reasoning During Planning, Erika Breann Miller
Mathematics Student Teachers' Curricular Reasoning During Planning, Erika Breann Miller
Theses and Dissertations
Teaching is a complex practice, in part because of all the decisions teachers make daily. This is especially true for student teachers who have little to no prior teaching experience to inform them about the decisions that need to be made in the classroom and how to reason through all those decisions as they plan and enact the lessons. Secondary mathematics student teachers were introduced to the Instructional Pyramid (Dingman et al., 2021) which organizes and maps teacher’s mathematical reasoning onto four elements of a classroom—teacher, student, mathematics, and curriculum—to examine which curricular reasoning aspects they use while planning mathematics …
Characterizing And Modeling The Nonlinear Behavior Of Additively Manufactured Trapped-Powder Dampers, Jonathan Knight Black
Characterizing And Modeling The Nonlinear Behavior Of Additively Manufactured Trapped-Powder Dampers, Jonathan Knight Black
Theses and Dissertations
Laser Powder Bed Fusion (LPBF) can be used to create metal parts with pockets of retained, unfused powder that serve as mechanical dampers. These trapped-powder dampers show promise for reducing the amplitude of vibrations at resonance by orders of magnitude. However, little is currently understood about the nonlinearity and repeatability of trapped-powder dampers, meaning that the design process currently consists of expensive trial-and-error prototyping and iteration. The present work contributes a corpus of experimental measurements for rectangular beams with trapped-powder dampers of various dimensions and locations. Preliminary testing revealed the presence of a memory effect which we hypothesize to be …
