Greener Synthesis Of Chlorophosphazenes, Andrew Mcgee
Greener Synthesis Of Chlorophosphazenes, Andrew Mcgee
Williams Honors College, Honors Research Projects
This project will attempt to synthesize chlorophosphazene molecules in the absence of solvents by using mechanochemical techniques in order to create a more environmentally friendly synthesis route. In this pursuit, various parameters will be changed including the milling ball to reagent ratios, the molar ratios of the reactants, and the addition of different catalysts. The products of each reaction will be characterized in order to determine success. This work builds upon existing efforts to utilize mechanochemical techniques in main group chemistry. The output of this project will be a report in ACS style and a poster to be presented for …
Design Of Pigments For Use In “Cool” Coatings, Tyler Laughorn
Design Of Pigments For Use In “Cool” Coatings, Tyler Laughorn
Williams Honors College, Honors Research Projects
This project was focused on the development and testing of several novel pigments that exhibit high NIR-reflectance and therefore show potential for use in “cool” coatings. A “cool” coating will reflect more solar radiation than other standard coatings, and so a coated structure would require less energy to keep cool. Four sets of pigments were synthesized: Co1-xMgxCr2O4 (teal), Co0.25Mg0.75Cr2-yAlyO4 (blue), Ti1-x-yNixSbyO2 (yellow), and Cr2-xFexO3 (black). NIR and TSR values were then measured …
The Role Of Influenza Infection On Cell Metabolism, Megha Mokkapati
The Role Of Influenza Infection On Cell Metabolism, Megha Mokkapati
Williams Honors College, Honors Research Projects
In this particular study global metabolomics LCMS data was analyzed to determine the effect of influenza infection on host metabolic processes. Specifically, wild-type male and female mouse lung samples from mice infected with PR8 (H1N1) or both PR8 and a reinfection of X31 (H3N2) were analyzed. The LC/MS(liquid chromatography-mass spectrometry) based global metabolomics will be performed on the samples using hydrophilic interaction liquid chromatography to separate polar analytes from the tissues (Dettmer, Aronov, 2007). Metabolites impacted by influenza infection in all samples will be analyzed to compare male and female mice, as well as differences between PR8 infection and X31 …
Development Of A Method For The Detection And Quantification Of Various Benzodiazepines And Z-Drugs In Human Blood And Qualitative Identification In Urine Samples Using Liquid Chromatography Mass Spectrometry (Lc-Ms/Ms), Haley Michel
Williams Honors College, Honors Research Projects
This method developed in the toxicology department at the Cuyahoga County Medical Examiner’s Office (CCMEO) detects 40 benzodiazepines and metabolites along with several z-drugs in blood and urine by liquid chromatography tandem mass spectrometry. A sample amount of 0.5 mL was used to detect analytes in postmortem drug facilitated sexual assault and impaired driving cases. Twenty-nine analytes met criteria for quantification while the remaining 14 were used as qualitative indicators. Bias and precision results for quality controls met criteria, staying within ±15% except for clonazolam and etizolam which were within ±20%. Quantitative reporting criteria which included dilution integrity was met …
Synthesis, Characterization, And Biological Activity Of Imidazolium Salts, David Weader
Synthesis, Characterization, And Biological Activity Of Imidazolium Salts, David Weader
Williams Honors College, Honors Research Projects
Nonmuscle invasive bladder cancer (NMIBC) inflicts thousands of Americans annually, and is typically treated with the immunotherapy BCG. However, due to a BCG shortage, there is a new need for novel treatments of NMIBC. Addressing this issue, several imidazolium salt derivatives were synthesized and characterized with the intent of treatment within the bladder. These imidazolium salts were tested against different human bladder cancer cell lines in vitro to determine their reactivity and cytotoxicity. Among these results are GI50 concentrations for each drug, which is the concentration of drug needed to see growth inhibition in 50% of treated cells. Previous published …
Filtration Apparatus Design For Oil-Water Separation Using Membranes And Sponges, Alec Jerger
Filtration Apparatus Design For Oil-Water Separation Using Membranes And Sponges, Alec Jerger
Williams Honors College, Honors Research Projects
It can be difficult to separate water and oil emulsions through traditional filtration. Therefore, investigations of filtering using thermo-responsive (TR) polymers, in this case poly(vinyl methyl ether) (PVME), was conducted. It’s hypothesized that below its lower critical solution temperature (LCST), PVME has an affinity for water while oil substances do not. Above the LCST the opposite will be true. To verify this hypothesis, iterations of filtration designs were created to provide optimum control over the parameters to measure flow. The final optimized experimental apparatus was a Chromaflex glass column which was air tight and controlled all parameters besides fluid flow. …
Synthesis Of Bio-Based Polymer Products, Joshua Sukie
Synthesis Of Bio-Based Polymer Products, Joshua Sukie
Williams Honors College, Honors Research Projects
The project covers the synthesis of two bio-based polymers. One aspect of the research investigates the synthesis of materials for use in vegetable oil-based UV-curable coating, and the subsequent polymerization of the materials into a coating film. The second aspect of the research follows the synthesis of a functionalized cellulose material for use as a reinforcer in a vegetable oil-based composite. Both products are subsequently analyzed by various methods.
