Research experiences for undergraduates (REUs) seek to increase the participating students’ knowledge and perceptions of scientific research through engagement in laboratory research and related activities. Various REU outcomes have been investigated, including influence on participants’ content knowledge, career plans, and general perceptions of their domains of research. The complexity of REUs and dynamic nature of student development provide opportunity for exploring how REUs influence student growth. Our research focused on first and second-year college students who participated in a residential REU program that took place in a chemistry department in a metropolitan university in the western United States. We assessed …
Synthesis Of Phosphorus-Based Hemiacetals For Potential Flame Retardants, Sara Alakkad
Synthesis Of Phosphorus-Based Hemiacetals For Potential Flame Retardants, Sara Alakkad
Honors Theses
Flame retardants which contain a phosphorus moiety attached to a carbohydrate backbone were developed. To synthesize the flame retardants, carbohydrates and polyols were used as the starting materials which occur in nature and are environmentally and toxicologically safe materials. The two target structures include one with a triose substructure and one with a pentose substructure. For both situations, however, multiple steps were taken for the synthesis of the flame retardant, as the carbohydrate needed to be generated into its protected form. The protected carbohydrate then interacted with a dialkyl phosphite, resulting in a phosphorous hemiacetal. This hemiacetal was then deprotected …
Exploration Of Protein-Protein Interactions Involving Deinococcus Radiodurans Pria, Dnab And Ssb, Christopher S. Morrow
Exploration Of Protein-Protein Interactions Involving Deinococcus Radiodurans Pria, Dnab And Ssb, Christopher S. Morrow
Honors Theses
Deinococcus radiodurans is a species of bacteria that has sparked a lot of interest since its discovery due to its incredible resistance to ionizing radiation. When exposed to ionizing radiation the genome of D. radiodurans will sustain over one hundred double stranded breaks. D. radiodurans demonstrates the ability to repair its genome and restart replication after sustaining, typically lethal, DNA damage. This project examined the mechanism of replication restart in D. radiodurans by investigating primosome protein PriA interacting with replicative helicase DnaB and single stranded binding protein. Many different types of gel electrophoresis were employed to investigate potential protein complex …
Synthesis Of Potential Phosphorus-Nitrogen Containing Flame Retardants, Colin Kloock
Synthesis Of Potential Phosphorus-Nitrogen Containing Flame Retardants, Colin Kloock
Honors Theses
Production of extremely efficient flame retardants is ideal because, in many instances, the amount of flame retardants that are added to pre-production to the mixture are so large that they can have an effect on the physical properties of the material. In addition, these types of polymers, when added during production, are homogenously mixed throughout the mixture which means not only uniform distribution and therefore function, but a less concentration of the retardants need to be used. Using Phosphorus-Nitrogen containing flame retardants in mixtures can have two means by which they function. First is the ability of P-N compounds to …
Kinetic Characterization Of B-Carotene In N-Hexane At Various Oxygen Concentrations, Katelyn Mary Arnold
Kinetic Characterization Of B-Carotene In N-Hexane At Various Oxygen Concentrations, Katelyn Mary Arnold
Honors Theses
We have characterized the photo – degradation of ẞC in oxygenated and deoxygenated n–hexane solvent and in the solid phase using broadband (BB; λ ≥ 200 nm) and 313 nm filtered output of a 100 W Hg Arc lamp. Oxygen concentrations of 0, 10, 20, and 100% were used in the solution phase studies. ẞC(s) did not photo – degrade upon exposure to BB light under air atmospheres; the mass and appearance of the samples, TLC chromatograms, and the absorption spectra were all identical pre- and post-irradiation. In the solution phase, the order of the photo – degradation with respect …
