Title: Raman and surface-enhanced raman spectroscopy of G-quadruplexes.
Creator: Friedman, Samantha, Terentis, Andrew C., Florida Atlantic University, Charles E. Schmidt College of Science, Department of Chemistry and Biochemistry
Abstract/Description: G-quadruplexes (G4s) are nucleic acid structures formed from π-stacked planar sets of four Hoogsteen hydrogen bonded guanine bases. G4s emerged as potential therapeutic targets based on their ability to modulate gene expression and inhibit the ability of telomerase to elongate chromosomal telomeres. Raman spectroscopy, polarized Raman spectroscopy, surface-enhanced Raman spectroscopy (SERS), and other optical spectroscopic techniques were used to characterize the G4s formed by four different...

G4s emerged as potential therapeutic targets based on their ability to modulate gene expression and inhibit the ability of telomerase to elongate chromosomal telomeres. Raman spectroscopy, polarized Raman spectroscopy, surface-enhanced Raman spectroscopy (SERS), and other optical spectroscopic techniques were used to characterize the G4s formed by four different DNA sequences: human telomeric (HT), thrombin-binding aptamer (TBA), nuclease hypersensitive element III1 region of the c- Myc gene promoter (Myc), and a single loop-isomer of Myc (MycL1).

Title: Phase-vanishing reactions with PTFE (teflon) as a phase screen.
Creator: Van Zee, Nathan J., Harriet L. Wilkes Honors College
Abstract/Description: Phase-vanishing reactions are triphasic reactions that involve a reagent, a liquid perfluoroalkane, and a substrate. In a phase-vanishing reaction with PTFE (polytetrafluoroethylene) tape as the phase screen instead of a liquid perfluoroalkane, there is no limitation related to the density of a phase, and the denser phase can be in the top layer. Additionally, PTFE tape is inexpensive, easy to use, and reusable. In this work we qualitatively described PTFE tape's thickness, stretching...
Show morePhase-vanishing reactions are triphasic reactions that involve a reagent, a liquid perfluoroalkane, and a substrate. In a phase-vanishing reaction with PTFE (polytetrafluoroethylene) tape as the phase screen instead of a liquid perfluoroalkane, there is no limitation related to the density of a phase, and the denser phase can be in the top layer. Additionally, PTFE tape is inexpensive, easy to use, and reusable. In this work we qualitatively described PTFE tape's thickness, stretching characteristics, and permeability. We investigated the phase-vanishing PTFE method's usefulness both in known transformations and also in a novel nucleophile-assisting leaving group (NALG) reaction with menthol, thionyl bromide, and zirconium(IV) chloride. We successfully used PTFE tape as a phase screen in bromination, bromolactonization, esterification, chemiluminescence, and tandem bromination/esterification phase-vanishing reactions. We found that the PTFE tape is an effective phase screen and useful in performing a slow addition of a reagent.

Title: Permeability of PTFE (teflon) tape as a phase screen in phase-vanishing reactions.
Creator: Parsons, Brendon A., Harriet L. Wilkes Honors College
Abstract/Description: PTFE (Teflon) tape has been reported as an alternative to liquid perfluoroalkanes in fluorous phase-vanishing (PV) reactions. Previous research on PV-PTFE reactions found that PTFE tape has unique characteristics compared to liquid flourous phase screens, including reagent permeabilities that are altered by exposure to certain organic solvents.

Show morePTFE (Teflon) tape has been reported as an alternative to liquid perfluoroalkanes in fluorous phase-vanishing (PV) reactions. Previous research on PV-PTFE reactions found that PTFE tape has unique characteristics compared to liquid flourous phase screens, including reagent permeabilities that are altered by exposure to certain organic solvents. This study investigates these characteristics by observing the effects of solvent adsorption on the diffusion of bromine and dimethyl phthalate. The directionality of solute diffusion in PV-PTFE chemiluminescence was also studied. Literature on Teflon films and on PV reactions is utilized to explain how the structural and chemical features of PTFE tape influence its permeability, and how solvents alter this permeability. We use structural arguments to explain why chemically-identical bulk PTFE behaves differently from PTFE tape. By better understanding how PTFE tape functions in PV reactions, the method may be improved and its use expanded.

Title: Biological electron transfer: an investigation of riboflavin.
Creator: Caplan, Stacee Lee, Harriet L. Wilkes Honors College
Abstract/Description: Most living organisms utilize electron transport chains in order to obtain energy. Riboflavin, commonly known as vitamin B2, is the central component of the redox coenzymes flavin adenine dinucleotide (FAD) and flavin mononucleotide (FMN). These cofactors serve as a prosthetic group to flavoproteins and function as the energy-carrying molecules in electron transfer reactions. In this study, the different ionization and oxidation states of riboflavin were identified and quantified as a...

These cofactors serve as a prosthetic group to flavoproteins and function as the energy-carrying molecules in electron transfer reactions. In this study, the different ionization and oxidation states of riboflavin were identified and quantified as a function of solution potential and pH. To accomplish this task, spectroelectrochemical reductions of riboflavin at different pH were performed. Spectroscopic data offer clues concerning the identity of underlying species, such as oxidation/ionization states and the controlling equilibria. The large data sets obtained from these experiments were analyzed and the acid dissociation constant for reduced riboflavin was determined.

Show moreEthylene is the simplest alkene. The carbon-carbon double bond is ubiquitous in the field of chemistry. Ethylene serves as the basis for understanding these molecules. Thus, the assignment of the electronic transitions in ethylene is an important endeavor that many scientists have undertaken, but are yet to decipher theoretically or experimentally. Synchrotron Radiation in the vacuum ultraviolet region allows for magnetic circular dichroism (MCD) measurements of ethylene and other simple alkenes. Studies of ethylene and propylene revealed that the páap* (AgáaB1u ethylene notation) transition is not the lowest energy transition. The páa3s(R) (AgáaB3u ethylene notation) is the lowest energy transition. To further this investigation, MCD and absorption measurement were carried out on isobutene. The isobutene spectra clearly showed four electronic transitions in the 156 to 212 nm wavelength region. These four isobutene transitions have been assigned as páa3s, páap*, páa3p(Sv (Band páa3px proceeding from lower energy to higher energy. The present results support the assignments in ethylene and propylene.

Show moreThis study explores the application of two methods of spectroscopy; Near Infrared spectroscopy (NIR) and Fourier transform spectroscopy (FTIR) as alternative approaches for measuring glucocorticoid metabolites in chimpanzee feces. The goals of this study were twofold: The first was to determine if cortisol can be identified within the NIR and/or FTIR spectra of chimpanzee fecal hormone extract in ethanol solution. The second objective was to determine the capability of NIR and FTIR to predict FGM concentrations obtained using standard laboratory methods. Fecal glucocorticoid concentrations measured by Enzyme Immunoassay were used as the reference data of partial least square (PLS) regression of fecal extract NIR spectra and FTIR spectra. Low accuracies (NIR: R2 = 0.152; FTIR: R2 = 0.199) were obtained from regression models using data from both methods. Though this study did not successfully demonstrate the feasibility of using NIR and FTIR to qualify and quantify FGMs, it is likely not a reflection of the capabilities of the technology, but rather of appropriate sample types and preparation methods.

Title: Changes in photoemission spectra across the order/disorder transition in copper-gold alloys.
Creator: Liu, Wei, Florida Atlantic University, Jordan, Robin G.
Abstract/Description: Ultra-violet photoemission spectroscopy has been used in this project to investigate the changes in photoemission spectra across the order/disorder transition in Cu-Au alloys. Many obvious changes are observed in the valence band spectra of the different phases, particularly in the area of Au-related states. In Cu3Au, the binding energy of Au-4f core levels in the ordered phase are shifted from the pure metal value by an average of 0.46 +- 0.05eV to increased binding energy. In CuAu, the...

In CuAu, the corresponding shift value in the ordered phase is 0.33 +- 0.05eV, also to increased binding energy. In both disordered Cu3Au and CuAu the value of the Au4f core level shift is reduced by 0.12eV from that of their ordered states. Some of the results are new, and others are in good agreement with previous studies.

Electrochemical impedance spectroscopy (EIS) was selected for development as a non-destructive method to characterize the degradation phenomena in carbon/nylon composites as result of moisture absorption. EIS data was collected for composites and neat resins as a function of immersion time in ambient and pressurized (6.2 MPa) 3.5% NaCl solution. EIS was also utilized to understand degradative mechanisms when composites were subject to cathodically induced damage. Concurrent EIS and 3-point mechanical loading was also performed on composites to study the changes in the impedance response as a function of loading. A detailed equivalent circuit analysis is also presented in an attempt to elucidate the degradation phenomena in composites. Gravimetric and 3-point mechanical testing data is also presented to study the effect of ambient and pressurized aqueous environments on composites. Scanning electron micrographs of composites are also included to assist in morphological evaluation.

Zn(0001) surfaces were prepared by vacuum cleaving and by Ar+ bombardment with annealing. LEED patterns and UPS spectra were taken on both the cleaved and bombarded Zn(0001) surfaces. The LEED patterns from cleaved surfaces showed 6-fold symmetry whereas those from bombarded surfaces showed a hexagonal array but with some differences: the spots with the same distances from the center of LEED pattern had different intensities and they were dimmer and more blurry compared to those from the cleaved surface. A value of 2.64+-0.07 A for the nearest neighbor spacing was determined from the LEED patterns. The UPS spectra showed that for both types of surfaces the 3d peak is at 9.8 eV with a spin splitting of 0.7 eV, which are in agreement with previous experimental and theoretical results. Differences in spectra between the two types of surfaces were found in the ratios of signal/background and in the ratios of the 3d doublet.

This work was preliminary and aided in describing the general performance of the battery. For analysis, the data was fitted to an equivalent electrical circuit using the Nonlinear Least Squares Method (NLSM). The correlation between theoretical and empirical data was sufficiently good.

Show moreThe study of the electrical properties of red blood cells (RBCs) plays a crucial role in advancing our understanding of human health. As RBCs age, they undergo changes that affect hemorheology and blood microcirculation, which have far-reaching implications for disease research. Furthermore, the shortage of RBC storage units can be a major issue for patients, underscoring the importance of characterizing RBC aging with respect to cell densities. In individuals with abnormal hemoglobin disease, alterations in hemoglobin and its functionality can modify the volume and density of RBCs, making their study even more crucial. To this end, our aim is to investigate the impedance alterations of RBCs after distributing them into different layers based on their densities. We have developed a novel method for non-invasive, rapid, and real-time single-cell analysis of RBCs. Our approach involves the use of electrical impedance spectroscopy (EIS) to study the cells after performing cell fractionation. Our studies indicate an increasing trend for RBC resistance and a decreasing trend for the cell membrane as the density of the layer increases. Additionally, we have developed a method for extracting hemoglobin with high purity from fresh samples of RBCs. By passing lysed RBCs through ultrafiltration devices and removing debris and membranes, we were able to isolate hemoglobin. Using the EIS technique, we studied the alterations of impedance over a frequency range, obtaining valuable insight into the electrical properties of hemoglobin.
