Theoretical Study Of Electronic Properties Of Functionalized Monolayers: Cu, Ag, Au, And Pt Atomic Wires On Graphene, H-Bn Monolayer, Silicene, And Phosphorene, Mythreyee T. Aasuri, Mukesh K. Choudhary, Narender Kumar, Ravindra Pandey

Michigan Tech Publications

The structural and electronic properties of graphene, h-BN monolayer, silicene, and phosphorene monolayers functionalized with Cu, Ag, Au, and Pt atomic wires were investigated using van der Waals─corrected density functional theory. These atomic wires form stable, functionalized monolayers that exhibit physisorption on planar monolayers and chemisorption on nonplanar ones. This results in either linear or bent configurations of the atomic wires, depending on the interface strength, leading to distinct electronic states. A weaker interface induces metal-induced gap states near the Fermi level, whereas a stronger interface results in covalently hybridized states farther from the Fermi level. Analysis of the electron …

Finiteness Of Torsion Loci And Normal Functions Arising From Cycles On Hadamard Products, Devin Akman

Arts & Sciences Graduate Student Theses and Dissertations

The unifying theme of this dissertation is normal functions. In the first chapter, we study an invariant of knot exteriors and similar manifolds called the A-polynomial through the lens of vanishing loci of normal functions. Using a special case of the Zilber-Pink conjecture, proven in the second chapter, we show that only finitely many irreducible Laurent polynomials of bounded overgenus appear as factors of A-polynomials. In the third chapter, we construct normal functions from hypergeometric variations of Hodge structure and compute their regulators. Finally, we determine under which conditions incomplete motivic cohomology cycles on families complete to cycles on their …

Influence Of Web Thickness And Concrete Cover On The Fire Resistance Of Aashto Type Iv Prestressed Concrete Bridge Girders, Fnu Nidhi

Electronic Theses and Dissertations 2020 - Present

Bridge fires caused by vehicle accidents, fuel tanker explosions and storage of combustible material beneath highway structures have led to severe structural damage and catastrophic collapse of prestressed concrete bridges. Critical structural collapse due to fire incidents such as I-85 prestressed concrete bridge girder collapse in Atlanta, 2017 and I-95 steel plate girder bridge partial collapse in Philadelphia, 2023 demonstrated the vulnerability of girders when exposed to extreme hydrocarbon fire temperatures exceeding 1000°C within few minutes. These events highlight the urgent need to better understand the thermal and structural behavior of bridge girders and explore design modifications that can enhance …

On Time-Series Analysis By Structured Matrix Decompositions With Applications To Signal Direction-Of-Arrival Estimation, Georgios Ierotheos Orfanidis

Electronic Theses and Dissertations 2020 - Present

Modern autonomous systems operating in highly dynamic, non-stationary environments require reliable inference from short, potentially corrupted time-series measurements, where conventional statistical methods relying on large-sample support and stationarity assumptions become fundamentally inapplicable. This dissertation develops a unified, model-free theoretical framework for time-series analysis, with a particular application to signal Direction-of-Arrival (DoA) estimation, grounded in structured matrix decompositions under both the L2-norm and L1-norm formulations.

We first approach the problem from a conventional viewpoint by carrying out standard matrix analysis directly on Hankel-structured representations of time-series data. In this context, we demonstrate that L1-norm decompositions of Hankel matrices offer strong resistance …

This is the introductory chapter of Reading With My Grandmother: Chinese Canadian Literature, History, and Family by Lindsay Diehl.

Reading With My Grandmother is an analysis of a range of Chinese Canadian literature that deepens the scholarly engagement by using elements of the author’s family’s story—her grandmother’s letters and photographs.

This engagement allows the author to simultaneously illustrate and participate in the varied ways Chinese Canadian literature has been imagined and produced in Canada in the last thirty-five years, examining texts such as Fred Wah’s biotext Diamond Grill (1996), Judy Fong Bates’ memoir The Year of Finding Memory (2010), and …

Exactly Solving One-Dimensional Models For The Fractional Quantum Hall Effect, Joseph R. Cruise

Arts & Sciences Graduate Student Theses and Dissertations

Nearly fifty years after its experimental debut, the quantum hall effect has produced perhaps more unique descriptions than any other subject of condensed matter physics. From topological band theory to non-commutative geometry, topological and conformal field theories, random matrix models and more, each approach captures a subset of the essential features, and compliments the others to produce a beautiful mosaic description. In this thesis, we revisit the fractional quantum hall (FQH) effect from its oldest vantage point, that of the trial wavefunctions and the parent Hamiltonians which stabilize them. Laughlin's observation of the importance of the theory of holomorphic functions …

Water-Driven Solid Electrolyte Interphase Governs Continuous-Flow Ammonia Electrosynthesis, Peng-Bo Liu, Sheng-Liang Zhai, Ji Huang, Zhong-Shuo Zhang, Jie Zeng, Shao-Feng Li

Journal of Electrochemistry

Flow-cell architectures have emerged as a powerful platform for continuous and stable lithium-mediated nitrogen reduction (Li-NRR), enabling ambient-condition electrochemical ammonia synthesis and offering a promising alternative to Haber-Bosch processes. However, Li-NRR is exceptionally sensitive to trace water, and even minor variations in water content can profoundly alter interfacial chemistry. Here, we systematically investigate how initial water concentration affects Li-NRR performance in a continuous-flow cell. Excess water drives the formation of a thick solid electrolyte interphase (SEI) layer, which may impede nitrogen access to metallic lithium and hinder lithium-ion transport. As a result, the ammonia Faradaic efficiency collapses from ~61% to …

Insertion Of Noble Metal Free Cathodic Catalyst Layer With Fe-N-C Catalyst For Boosted Performance Of Pemfc, Shi Zhou, Muhammad Tariq, Asif Nadeem Tabish, Muhammad Salman, Fan-Di Ning, Muhammad Rayyan Tayyab, Ran-Ran Peng, Meng-Geng Hao, Wen-Mu Li, Xiao-Chun Zhou

Journal of Electrochemistry

Economical Fe-N-C catalysts are considered as promising alternatives to platinum group metal catalysts for proton exchange membrane fuel cells (PEMFCs). Despite exhibiting robust activity on rotating disk electrodes, their performance within membrane electrode assemblies often experiences limitations, such as decreased O₂ diffusion, high H₂O₂ formation, low proton conduction, and a lower electron transfer number. In this study, key factors, including proton transport, electron conduction, and gas diffusion within air-breathing PEMFCs, have been investigated by adjusting cathode catalyst layer (CCL) compositions. From the experimental results, the optimal peak power density was obtained when the loading of Fe-N-C …

Cognition Is Not Content: A Structural Account Of Processing Conditions, Griselda Poe

Publications and Research

Human cognition has been described in terms of content. This description becomes insufficient once artificial systems make output observable apart from subject attribution, intention, and relational context. Under this contrast condition, what becomes visible is a layered structure in which output, reconstruction, evaluation, and termination do not necessarily coincide. The same input may register as complete under one processing condition while remaining unresolved under another. This separability means that content-based description does not merely omit an additional variable: it can mislocate a processing difference as a difference in meaning, personality, intention, ability, or attitude. This is not a proposal for …

Musical Affinities Between Ann Southam's Glass Houses And Canadian Fiddle Tunes With Performance Considerations For Glass Houses No. 5, Evangelia Nikolaidou

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Ann Southam stands as one of Canada’s foremost minimalist composers. Her fifteen-piece piano set Glass Houses, composed in 1981 and revised in 2009, reflects the joyful, dance-like energy of Canadian fiddle music that inspired it. While Glass Houses has frequently been discussed within the context of minimalist composition, less attention has been given to the ways in which the work resonates with Canadian fiddle traditions. This document draws on existing scholarship on Métis, French-Canadian, Newfoundland, Anglo-Canadian, and Scottish fiddle traditions to trace and clarify structural, rhythmic, and textural affinities between Canadian fiddle tunes and Glass Houses. Focusing on …

Covid Minds: A Thematic Review Of The Pandemic On Neural Mechanisms And Political Polarization, Madison Jeffries

Honors Projects

This paper analyzes how the COVID-19 pandemic influenced political polarization in the United States by examining the interactions between social system disruption, psychological stress, and underlying neurological behaviors. While previous research has extensively discussed pandemic's influence on public health and societal breakdowns, studies fail to examine how these disruptions shaped political divisions. This study synthesizes interdisciplinary literature on pandemic-induced stressors and analyzes factors, including institutional mistrust and social isolation, and how these experiences shape political behavior and perspectives. Applying research from psychology and neuroscience, the paper argues that prolonged exposure to pandemic-related stressors changed neurological and behavioral patterns in response …

Complexity Of The Zero Set Of A Matrix Schubert Ideal, Cesar Julian Meza

Arts & Sciences Graduate Student Theses and Dissertations

T-varieties are normal varieties equipped with an action of an algebraic torus T. When the action is effective, the complexity of a T-variety X is dim(X)−dim(T). Matrix Schubert varieties, introduced by Fulton in 1992, are T-varieties consisting of n×n matrices satisfying certain constraints on the ranks of their submatrices. In this dissertation, we focus on the complexity of certain torus-fixed affine subvarieties of matrix Schubert varieties. Concretely, given a matrix Schubert variety X_w where w∈S_n, we study the complexity of Y_w obtained by the decomposition X_w = Y_w ×C^k with k as large as possible. Building on results by Escobar–Mészáros …

Molecular Catalysts For Electrochemical Nitrogen Activation Toward Sustainable Ammonia Synthesis, Jin-Xiu Han, Hao Xue, Xian-Biao Fu

Journal of Electrochemistry

Homogeneous electrocatalytic nitrogen reduction reaction (NRR) provides a powerful framework to interrogate molecular nitrogen-fixation pathways under mild conditions. By tuning the metal center, ligand architecture, and reaction medium, these systems enable capturing key intermediates and delivering mechanistic insight at the molecular-level resolution. Nevertheless, advances remain constrained by highly reduced operating potentials, intense competition from the hydrogen evolution reaction (HER), limited durability in turnover, and inadequate long-term stability.

In this review, we take electron delivery to the molecular active site as the guiding principle for organizing homogeneous electrochemical N₂ activation and transformation. We classify reported systems into direct electron transfer …
