Development Of Granulated Adsorbent For Clean-Up Of Water Contaminated By Cesium, Esther Alorkpa 2019 East Tennessee State University

Development Of Granulated Adsorbent For Clean-Up Of Water Contaminated By Cesium, Esther Alorkpa

Electronic Theses and Dissertations

A study was conducted on sol-gel synthesis of an adsorbent (phosphotungstic acid embedded in silica gel, H-PTA/SiO­2) of radioactive cesium. A novelty of this work is covalent bonding of PTA to the surface of solid support that prevents leaching from the surface of the material. The sample was granulated with a binder, aluminium oxide (γ-Al2O3). Solid-state NMR and FT-IR spectroscopy were used to confirm the presence of Keggin units of PTA in the bound materials. Thermal analysis of H-PTA/SiO­2 - γ-Al2O3 (50 %) showed that the water content in the bound material ...

Conformational Dynamics Of The Hiv-Vif Protein Complex, K. Aurelia Ball, Lieza Chan, David J. Stanley, Elise Tierney, Sampriti Thapa, Hai M. Ta, Lily Burton, Jennifer M. Binning, Matthew P. Jacobson, John D. Gross

K. Aurelia Ball

Human immunodeficiency virus-1 viral infectivity factor (Vif) is an intrinsically disordered protein responsible for the ubiquitination of the APOBEC3 (A3) antiviral proteins. Vif folds when it binds Cullin-RING E3 ligase 5 and the transcription cofactor CBF- β. A five-protein complex containing the substrate receptor (Vif, CBF- β, Elongin-B, Elongin-C (VCBC)) and Cullin5 (CUL5) has a published crystal structure, but dynamics of this VCBC-CUL5 complex have not been characterized. Here, we use molecular dynamics (MD) simulations and NMR to characterize the dynamics of the VCBC complex with and without CUL5 and an A3 protein bound. Our simulations show that the VCBC ...

Making Scents: The Relationship Between Insect Visitors And Chemical Fragrance Composition Of Cypripedium Parviflorum Var. Pubescens In Central Virginia., Ruth Elkins

Student Scholar Showcase

Due to its rarity, little is known regarding which insects pollinate Cypripedium parviflorum var. pubescens, large yellow lady slipper orchids, and why they do so when offered no reward. Insect identification and fragrance composition data have been collected from two populations of large yellow lady slippers in Central Virginia for more than a decade. This research analyzed data in order to determine potential relationships between visiting insects and fragrance compositions of the orchid. The results of this research can be used to establish and protect populations of Cypripedium parviflorum var. pubescens.


Elemental Analysis Of Legacy Sediments At College Lake, Amelia Dalton 2019 University of Lynchburg

Elemental Analysis Of Legacy Sediments At College Lake, Amelia Dalton

Student Scholar Showcase

College Lake is a large reservoir located on the campus of the University of Lynchburg. College Lake’s ecosystem has degraded over the years due to the buildup of sediment, nutrients, and raw sewage. Increased urbanization in the area has also most likely contributed to the contaminants present within the system. Because of flooding issues during the summer of 2018, Lynchburg CIty officials drained College Lake, which caused sediment to be released downstream. To better understand the transport of heavy metals in the sediments released from College Lake, sediment core samples were taken from College Lake, Hollins Mill Park, and ...


Mobilization Of Calcium Across Mineralized Tissues In Yellow Perch, Perca Flavescens, Taylor Bopp 2019 University of Lynchburg

Mobilization Of Calcium Across Mineralized Tissues In Yellow Perch, Perca Flavescens, Taylor Bopp

Student Scholar Showcase

Bones in many higher teleost fish, such as percids and centrarchids, lack osteocytes that function as both chemo- and mechano-sensors, and thus, are not actively involved in homeostasis of blood calcium level. Nonetheless, the vertebrae of yellow perch, Perca flavescens (P. flavescens), living in darker and low calcium (Ca) water, have demonstrated adaptive modeling and remodeling of vertebrae to be more mineralized and thus enhance transmission of the axial muscle torque into the thrust force for the C-start predator escape behavior. The prey-predator interaction is expected to occur at closer range between prey fish and predator fish in darker water ...


Synthesis Of Cyclopropyl Analogs Of Acetylcholine, Douglas Armstrong, Zachary Emptage 2019 Olivet Nazarene University

Synthesis Of Cyclopropyl Analogs Of Acetylcholine, Douglas Armstrong, Zachary Emptage

Scholar Week 2016 - present

The Ph.D. research by Douglas Armstrong was highly successful for the synthesis of the trans cyclopropyl analog of acetylcholine, but only marginally successful for the cis isomer. In recent years he has developed novel ideas as to how the synthesis of the cis isomer may be improved upon, in ways using more current methods. He has done experiments using some of those methods, and the results, although preliminary, look good.

Synthesis Of A Hydrophobic/Hydrophilic Nano-Patterned Metal-Organic Framework Material, Daniel Pivaral 2019 Kansas State University Libraries

Synthesis Of A Hydrophobic/Hydrophilic Nano-Patterned Metal-Organic Framework Material, Daniel Pivaral

Kansas State University Undergraduate Research Conference

Metal-Organic Framework (MOF) materials are supramolecular structures that are formed from the assembly of organic molecules that[AL1] have multiple binding sites with compatible metal cations. The resulting structure is a uniform and porous 3D grid-like with metal vertices that are connected by organic linkers. MOFs have several potential uses such as catalysis, detection, and gas storage, and new strategies to synthesize functional MOFs continue to be developed. One strategy is post synthetic modification (PSM), a process where different chemical groups are grafted onto the organic linkers via chemical reaction. The main objective of this research is to demonstrate that ...


Effects Of Disorder On Thermoelectric Properties Of Semiconducting Polymers, Zlatan Aksamija, Dhandapani Venkataraman, Connor J. Boyle, Meenakshi Upadhyaya 2019 University of Massachusetts - Amherst

Effects Of Disorder On Thermoelectric Properties Of Semiconducting Polymers, Zlatan Aksamija, Dhandapani Venkataraman, Connor J. Boyle, Meenakshi Upadhyaya

Zlatan Aksamija

Organic materials have attracted recent interest as thermoelectric (TE) converters due to their low cost and ease of fabrication. We examine the effects of disorder on the TE properties of semiconducting polymers based on the Gaussian disorder model (GDM) for site energies while employing Pauli’s master equation approach to model hopping between localized sites. Our model is in good agreement with experimental results and a useful tool to study hopping transport. We show that stronger overlap between sites can improve the electrical conductivity without adversely affecting the Seebeck coefficient. We find that positional disorder aids the formation of new ...

Hour-Level Resolution On Consumption Pattern Of Substance Abuse, Jarrett Mauk, Rhiannon Huffines, Brittney Nelson, Tara Croft, Bikram Subedi

Scholars Week

Conventional survey-based approaches of determining the consumption statistics of drugs in communities are suffered from non-response biases, and typically underestimate the actual consumption. Time and cost-intensive conventional approaches, therefore, can’t be utilized to determine high-resolution temporal variability in drug consumption. In this study, the temporal trend of consumption of 10 illicit and 26 prescribed neuropsychiatric drugs was determined at hour-level resolution utilizing wastewater-based epidemiology. The hourly composite raw wastewater (every 10 minutes) samples were collected for three consecutive days in a typical week (total of 72 samples), analyzed for target drug residues using UPLC-MS/MS, and back-calculated the consumption ...


Uncertainties Treatment For Wastewater-Based Epidemiological Estimation Of The Consumption Of Illicit And Prescribed Neuropsychiatric Drugs In Two Urban Communities In Kentucky Using Ammonium Normalized Population And Monte Carlo Simulation, Rhinannon Huffines, Tara Croft, Manoj Pathak, Bikram Subedi 2019 Murray State University

Uncertainties Treatment For Wastewater-Based Epidemiological Estimation Of The Consumption Of Illicit And Prescribed Neuropsychiatric Drugs In Two Urban Communities In Kentucky Using Ammonium Normalized Population And Monte Carlo Simulation, Rhinannon Huffines, Tara Croft, Manoj Pathak, Bikram Subedi

Scholars Week

The conventional estimation of the prevalence of substance use in a community based on self-reported surveys typically underestimates the actual consumption. Drug’s residues in raw wastewater collected from the centralized wastewater treatment plants were utilized – Wastewater-Based Epidemiology (WBE) – to determine the consumption rate of illicit and prescribed neuropsychiatric residues in two urban communities in eastern Kentucky and two rural communities in western Kentucky. The ammonical nitrogen content in raw wastewater samples was used to minimize the uncertainty associated with the population dynamicity. Uncertainties associated with the several WBE parameters to back-calculate the consumption rate of drugs such as flow ...

The Effects Of Cannabidiol And Delta 9-Tetrahydrocannabinol Concentration On Breast Cancer Cells, Dorothy Agyemang

Ursidae: The Undergraduate Research Journal at the University of Northern Colorado

Delta 9-tetrahydrocannabinol (THC) and cannabidiol (CBD) are phytocannabinoids that have a potential impact on cancer treatments. Studies have shown that certain cannabinoids cause cancer cells to die, but only with the right concentration, which has not been well documented. The purpose of this study is to determine the exact concentration of CBD and THC needed to kill MCF-7 breast cancer cells. In this experiment, the initial treatment group will be treated with CBD or THC at concentrations of 0.1, 1, 10 and 100 micromolar. These concentrations were arbitrarily chosen because there is not an established baseline. Cell metabolic activity ...

Showcase of Faculty Scholarly & Creative Activity

In the past 100 years IUPAC has become well known for the development of nomenclature standards for chemicals and terminology for communication of chemically related concepts. Initially published in IUPAC's Pure and Applied Chemistry (PAC), terminology recommendations have been incorporated into the IUPAC Color Books published by the divisions. Subsequently, many terms from the color books have been incorporated into the Gold Book - the Compendium of Chemical Terminology. While the work to date as been focused on the standardization of concept (term) definitions for human use, the aggregated set of all PAC recommendations on terminology constitutes a corpus of ...


Monitoring Transverse Relaxation Times Of Kerosene-Adulterated Diesel Using Low-Field Nuclear Magnetic Resonance Spectroscopy, Tristen Rumbaugh 2019 Harrisburg University of Science and Technology

Monitoring Transverse Relaxation Times Of Kerosene-Adulterated Diesel Using Low-Field Nuclear Magnetic Resonance Spectroscopy, Tristen Rumbaugh

Experiential Learning Projects

Time-domain nuclear magnetic resonance spectroscopy (TD-NMR) and low-field nuclear magnetic resonance spectroscopy (LF-NMR) are different techniques that vary in the range of magnetic field strengths that they use, which is a determining factor for the type of analysis that can be done. In this study, LF-NMR was used to perform a time-domain analysis of petroleum products, diesel and kerosene. This is a type of analysis which is typically performed using TD-NMR. Diesel and kerosene are two petroleum products that have different characteristics such as viscosity, boiling point, and hydrocarbon length. Diluting, or adulterating, diesel fuels with kerosene is a common ...
