Computational Investigation into the Mechanisms and Origins of Selectivity in Selected Organic and Organometallic Chemical Processes

Creator:: Harper, Jordan L.
Abstract:: Put generally, the work I have conducted in my time at Oregon State University has been to answer two questions. The first of these is “Why do I get this particular product from this particular chemical reaction?” and the second is “How do the reagents in this chemical reaction lead...

Part I : development and application of an arsenic speciation technique using ion-exchange solid phase extraction coupled with GFAAS ; Part II : investigation of zinc amalgam as a reductant

Creator:: Bos, Mark C.
Abstract:: Two related techniques, based upon ion-exchange solid phase extraction, have been developed for the determination of arsenic speciation. The inorganic arsenic species arsenite (As(III)) and arsenate (As(V)) are separated by anion-exchange and detected with graphite furnace atomic absorption spectrophotometry (GFAAS) with a nickel matrix modifier. The first separation technique, which...

Studying fusion reactions for effect of PCN on heavy nucleus formation and for nuclear structure effects

Creator:: Naik, Radhika
Abstract:: The fusion reaction ²⁰⁸Pb (⁵⁰Ti, xn) ²⁵⁸⁻x Rf (x = 1-3) was studied to determine PCN (probability that the mononucleus system evolves to form a compound nucleus inside the fission saddle point) and to establish the value of Wsur (survival probability) for the given reaction experimentally. The fission excitation function...

Determination of Reaction Product Cross Sections in the ¹³⁶Xe + ²⁰⁸Pb Multi-nucleon Transfer Reaction at E[subscript cm] = 450 MeV

Creator:: Barrett, J. Spencer
Abstract:: The yields of 235 projectile-like and target-like fragments from the interaction of ¹³⁶Xe with a thick target of ²⁰⁸Pb at a center-of-mass energy, E[subscript cm], of 450 MeV were measured using γ-γ-γ coincidence data from Gammasphere and off-line γ-ray spectroscopy. The results give an expansive picture of the production cross...

Fiber optic sensors and spectrometry for the detection of volatile gem-polyhalogenated hydrocarbons

Creator:: Louch, Jeff
Abstract:: A fiber optic fluorometer utilizing a double-fiber optic probe was constructed. The absolute fluorescence signal and effective collection efficiency are approximately one fifth those of typical cuvette fluorometers and agree with those predicted by theory. A quinine sulfate calibration curve shows linearity from a detection limit of 10 pg/mL to...

A microcomputer automated anodic stripping voltammetric analyzer for trace heavy metal speciation

Creator:: Dewald, Lamar Robert
Abstract:: An automated instrument based on a single-board microcomputer was developed for use in voltammetric analyses. Operator input of numerous experiment parameters allows any type of voltammetric analysis to be implemented and multiple scans to be run unattended. A three operational amplifier potentiostat is used to control the cell voltage and...

The kinetic and radiolytic aspects of control of the redox speciation of neptunium in solutions of nitric acid

Creator:: Precek, Martin
Abstract:: Neptunium, with its rich redox chemistry, has a special position in the chemistry of actinides. With a decades-long history of development of aqueous separation methods for used nuclear fuel (UNF), management of neptunium remains an unresolved issue because of its not clearly defined redox speciation. Neptunium is present in two,...

Novel ternary graphite intercalation compounds of alkali metal cations and amines

Creator:: Maluangont, Tosapol
Abstract:: Novel ternary graphite intercalation compounds (GICs) of alkali metal cations and a wide variety of amines have been synthesized by one-pot chemical syntheses. Alkali metals studied includes Li, Na and K. The families of amines employed are nalkylamines, branched alkylamines, and different structural isomers of diamines and polyamines. Intragallery structures...

Excited state molecular structural evolution and chemical reactivity studied by femtosecond stimulated Raman spectroscopy

Creator:: Han, Fangyuan
Abstract:: In this dissertation, my research work on excited state dynamics of small organic molecules in solutions is presented. Using femtosecond stimulated Raman spectroscopy (FSRS) as the main experimental tool, the excited state hydrogen-bonding dynamics (ESHBD) of Coumarin 102, a common laser dye molecule, in ethanol solution is examined with <150...
