Theoretical Model Of Femtosecond Coherence Spectroscopy Of Vibronic Excitons In Molecular Aggregates, Alexander J. Rode, Paul C. Arpin, Daniel B. Turner Apr 2024

Theoretical Model Of Femtosecond Coherence Spectroscopy Of Vibronic Excitons In Molecular Aggregates, Alexander J. Rode, Paul C. Arpin, Daniel B. Turner

Materials Science and Engineering Faculty Publications and Presentations

When used as pump pulses in transient absorption spectroscopy measurements, femtosecond laser pulses can produce oscillatory signals known as quantum beats. The quantum beats arise from coherent superpositions of the states of the sample and are best studied in the Fourier domain using Femtosecond Coherence Spectroscopy (FCS), which consists of one-dimensional amplitude and phase plots of a specified oscillation frequency as a function of the detection frequency. Prior works have shown ubiquitous amplitude nodes and π phase shifts in FCS from excited-state vibrational wavepackets in monomer samples. However, the FCS arising from vibronic-exciton states in molecular aggregates have not been …

Electrocatalytic Cyclopropanation Of Active Methylene Compounds, Liang-Hua Jie, Hai-Chao Xu Apr 2024

Electrocatalytic Cyclopropanation Of Active Methylene Compounds, Liang-Hua Jie, Hai-Chao Xu

Journal of Electrochemistry

The development of novel strategies to access cyclopropanes has become increasingly important due to the vital role of these three-membered ring structures in synthetic intermediates, natural products, and pharmaceuticals. Herein, we present an electrocatalytic method for the synthesis of cyclopropanes through intermolecular dehydrogenative annulation of active methylene compounds and arylalkenes. This electrochemical process requires no chemical oxidants, allowing for a speedy access to various functionalized cyclopropanes from inexpensive and readily available materials.

Electrochemical Syntheses Of Aryl-Substituted Benzothiophenes And Phenanthrenes Using Benzenediazonium Salts As The Aryl Radical Precursors, Li-Yuan Lan, Yang-Ye Jiang, Raymond Daniel Little, Cheng-Chu Zeng

Journal of Electrochemistry

Aryl-substituted benzothiophene and phenanthrene are important structural units in medicinal chemistry and materials science. Although extensive effort has been devoted to prepare these compounds and a variety of approaches have been developed to construct the 2-substituted benzothiophene core structure, environmental-friendly and efficient synthetic means are still desired. Based on our previous electrochemical Minisci-type arylation reaction with aryl diazonium salt as the aryl precursor, as well as the work from König’s group, herein, we described the use of paired electrolysis to achieve 2-aryl benzothiophenes and 9-aryl phenanthrenes employing benzenediazonium salts as the aryl radical precursors. Initially, 2-methylthiobenzendiazonium salt 1a and 4-methylbenzene …

Electrochemical Advanced Treatment Of Desulfurization Wastewater From Coal-Fired Power Plants, Ju-Cai Wei, Juan Yi, Xu Wu Apr 2024

Electrochemical Advanced Treatment Of Desulfurization Wastewater From Coal-Fired Power Plants, Ju-Cai Wei, Juan Yi, Xu Wu

Journal of Electrochemistry

Zero-emission of desulfurization wastewater is one of the main demands for coal-fired power plants. As typical high salinity wastewater, it is hard to purify the desulfurization wastewater from coal-fired power plants through traditional physicochemical treatment or biochemical treatment, e.g., COD and Cl–. A high concentration of Cl– ion in desulfurization wastewater restricts wastewater reuse and zero-emission. Electrochemical technology is an attractive method for high salinity wastewater zero-emission, which provides a versatile, efficient, cost-effective, easily automatable, and clean industrial process. For advanced treatment of effluent after triple box process treatment in power plants, this paper reports an electrochemical …

Representation Theory And Burnside's Theorem, Nathan Fronk Apr 2024

Representation Theory And Burnside's Theorem, Nathan Fronk

Senior Seminars and Capstones

In this paper we give a brief introduction to the representation theory of finite groups, and by extension character theory. These tools are extensions of group theory into linear algebra, that can then be applied back to group theory to prove propositions that are based entirely in group theory. We discuss the importance of simple groups and the Jordan-Hölder theorem in order to prepare for the statement of Burnside’s pq theorem. Lastly, we provide a proof of Burnside’s theorem that utilizes the character theory we covered earlier in the paper.

Simulating Ice Particle Properties Under Varying Electric Fields, Joseph Cooney

Physics Capstone Projects

In this study, the interactions between atmospheric water molecules and an electrically charged dust particle were simulated in python to determine the role of electric charge and electric fields in atmospheric ice formation. Multiple levels of electric charge were tested, corresponding to different strengths of atmospheric electric fields. The TIP4P-2005 model for water was used to simulate these molecules under the influence of a central electric potential to represent the charged dust particle. These included a control group with no electric field (0 C), a group under a fair-weather strength of electric field (1.6*10-14 C), a foul-weather electric field (1.6*10-12 …

Synthesis And Characterization Of Silver(I) And Manganese(Ii) Complexes With Thione Imidazoles, Shannon Keyser, Audrey Lawrence, Jaime M. Murphy Ph.D.

Honors Theses

Coordination polymers are chemical complexes with versatile applications such as catalysts, electrical conduc-tors, non-linear optics, magnetics, chemical sensing, and molecular storage. The polymers are comprised of a repeating series of metal-ligand complexes, which form various structures in varying ratios depending on the metal and ligand used. Certain metal-ligand combinations have shown particular promise as potentially being polymers or, if not polymers, possessing other useful features such as electromagnetic conductivity. Complexes were synthesized using silver(I) and manganese(II) with the ligands methimazole, 2-mercaptoimidazole, and thiocarbanilide with counterions of either chloride or nitrate. These com-plexes were characterized using elemental analysis, infrared spectroscopy, and …

The Purification And Thermal Stability Of The Peroxidase Enzyme In Cucurbita Moschata, Garen Hamner Apr 2024

The Purification And Thermal Stability Of The Peroxidase Enzyme In Cucurbita Moschata, Garen Hamner

Senior Honors Theses

Peroxidases are enzymes that catalyze the reduction of hydrogen peroxide to water while oxidizing organic substrates and are valuable in spheres like industrial and medical applications and histochemistry. Limitations still exist in the use of the well-studied horseradish peroxidase for certain activities due to limitations like poor thermal stability, thus the search for novel peroxidases that can overcome these limitations is an active area of research. Butternut squash peroxidase (Cucurbita moschata) (BSP) shows promise due to significant activity being found in the skin and apparent enhanced thermal stability, but an efficient purification scheme for it is lacking, as well as …

The Contradiction Between Use-Value And Exchange-Value: Ecology, Imperialism, And The Telos Of Production, Larry Alan Busk, Elizabeth Portella Apr 2024

The Contradiction Between Use-Value And Exchange-Value: Ecology, Imperialism, And The Telos Of Production, Larry Alan Busk, Elizabeth Portella

Emancipations: A Journal of Critical Social Analysis

This article elaborates and defends a critique of capitalism which, despite its appearance in various bodies of work, has not been named or systematically differentiated. The critique locates a contradiction between production for use-value and production for exchange-value, or a contradiction in what we call “the telos of production.” While maintaining that it has some basis in Marx’s work, we defend this model as preferable to the critique of capitalism based strictly on the exploitation of labor (which we call the “exploitation-exclusive critique”). We attempt to show this by applying the two approaches to the empirical realities of the ecological …

The Symbolic Capital Of The Neoliberal University, Chad Lavin Apr 2024

The Symbolic Capital Of The Neoliberal University, Chad Lavin

Emancipations: A Journal of Critical Social Analysis

The paper examines the concerns about the enduring value of liberal education in the broader context of a shift from a liberal to a neoliberal society. While so much literature on “the neoliberal university” tends to characterize neoliberalism as a hostile force invading the sacred space of the university, the knowledge comprising neoliberalism is in large part the product of research coming out of universities. Using the concept of symbolic capital to explore the role of university researchers in developing and consecrating neoliberal ideas, the paper argues that even in this era of heightened skepticism toward experts and expertise, university …

Interpolation And Quadrature, Abigail Poleway Apr 2024

Interpolation And Quadrature, Abigail Poleway

Academic Festival

In this poster, we will first examine polynomial interpolation. Interpolation allows us to construct a polynomial through a given set of data points. Interpolation is also used to develop the Newton-Cotes formulas, which are methods for numerical integration, or quadrature, that can approximate more complicated definite integrals. But, there is a way to arrive at even more precise approximations, and we will discover this through a discussion of Gaussian Quadrature.

Indigenous Communities Are Disproportionately Burdened By Environmental Contamination, Rae Cade, Danlin Yu, Kyle Whyte, Pankaj Lal, Cortni Borgerson Apr 2024

Indigenous Communities Are Disproportionately Burdened By Environmental Contamination, Rae Cade, Danlin Yu, Kyle Whyte, Pankaj Lal, Cortni Borgerson

Student Research Symposium

Indigenous populations are disproportionately affected by both environmental pollution and health disparities resulting in mortality rates 60% higher than their white counterparts. Previous research has revealed instances of pollution from facilities which have caused severe health issues in Indigenous communities. Despite this, widespread geographic studies of the spatial correlation between Environmental Justice (EJ) and Indigenous populations remain lacking. This chapter examines whether Indigenous people in the northeastern United States are inequitably burdened by contamination. I find that Indigenous people are disproportionately exposed to 21 superfund contaminants, regardless of state or federal recognition. The sources of these contaminants varied, ranging from …

X-Ray Fluorescence Analysis Of Historic Art Paint Pigments, Sofia A. Stirpe, Juergen Thieme Apr 2024

X-Ray Fluorescence Analysis Of Historic Art Paint Pigments, Sofia A. Stirpe, Juergen Thieme

Binghamton University Undergraduate Journal

Utilizing synchrotron radiation, X-ray fluorescence (XRF) microscopy enables researchers to deduce the elemental composition of paint pigments with a higher sensitivity and resolution than that of lab-based XRF instruments. With this information, art historians can date paintings by examining the elemental makeup of paint pigments and the time periods in which they were used. One painting, Christ and the Woman Taken in Adultery, has been duplicated by Pieter Brueghel the Younger and other artists, leading to confusion over which artworks are Brueghel masterpieces or copies by other artists. Art historian Maurizio Seracini, retaining a painting that could be assigned …
