Catalytic Activity Of Molybdenum-Dioxo Complexes, Randy Tran
Catalytic Activity Of Molybdenum-Dioxo Complexes, Randy Tran
Graduate Theses and Dissertations
This dissertation details the development of rationally designed dioxomolybdenum catalyst active for deoxydehydration (DODH), the net reduction of diols and polyols into alkenes and dienes. Catalyst design involved variations on dioxomolybdenum(VI) supported by a dianionic meridional pincer ligand. Rational substrate scope was explored using aliphatic diols, aromatic diols, and biomass derived diols. Various reductants were tested for ability to catalyze the reaction. The substrate specific mechanism of DODH was explored utilizing NMR and in-situ infrared spectroscopy and important rate constants and rate determining steps were found to aid in the optimization of ideal reaction conditions. Catalytic activity was observed to …
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 …

Green Chemistry Oxidative Modification Of Peptoids Utilizing Bleach And Tempo, Jesse Leland Roberts
Graduate Theses and Dissertations
Biotherapeutic drugs, derived from biological molecules such as proteins and DNA, are becoming an integral and exceptionally critical aspect of modern medicine. Compared to common pharmaceutical drugs, biotherapeutics are much larger in size and have greater target specificity, allowing them to treat many chronic diseases ranging from cancer to rheumatoid arthritis. The major issue with protein based therapeutics is that they readily undergo proteolysis, or enzymatic degradation, when administered through subcutaneous injections. Traditionally, biotherapeutic modification procedures have centered on the use of PEG derivatives. This process, called PEGylation, is unfavorable due to the increases in molecular weights of the proteins …

Extraordinary chemical and physical properties exhibited by nanomaterials, as compared to their bulk counterparts, have made the area of nanotechnology a growing realm in the past three decades. It is the nanoscale size (from 1 to 100 nm) and the morphologies of nanomaterials that provide several properties and applications not possible for the same material in the bulk. Magnetic and optical properties, as well as surface reactivity are highly dependent on the size and morphology of the nanomaterial. Diverse nanomaterials are being widely used in molecular diagnostics as well as in medicine, electronic and optical devices. Among the most studied …
