Temperature Dependence of Cu₃₋xSb₁₋[subscript y]M[subscript y]S₄ (M=Sn,Ge) Resistivity and Thermopower

Creator:: Mutch, Joshua
Abstract:: An experimental apparatus is modified to allow measurements of the Seebeck coefficient and resistivity to be taken simultaneously. This apparatus is designed for bulk and thin film samples between temperatures of 10 K and 300 K. The apparatus is constructed such that these simultaneous measurements do not interfere with each...

Detection of exciton polaritons in organic thin film TES-ADT

Creator:: Haas, David P.
Abstract:: Exciton polaritons are quasiparticles composed of a quantum superposition of matter and light states that arises from the coupling of a standing wave photon and an exciton. This research has two primary objectives: to design and fabricate a Fabry-Perot microcavity system in which to produce exciton polaritons; and to show...

Neutron Capture Cross Sections of Cadmium Isotopes

Creator:: Gicking, Allison
Abstract:: The neutron capture cross sections of ¹⁰⁶Cd, ¹⁰⁸Cd, ¹¹⁰Cd, ¹¹²Cd, ¹¹⁴Cd and ¹¹⁶Cd were determined in the present project. Four different OSU TRIGA reactor facilities were used to produce redundancy in the results and to measure the thermal cross section and resonance integral separately. When the present values were compared...

The contact value approximation to the pair distribution function for an inhomogeneous hard sphere fluid

Creator:: Lurie-Gregg, Paho
Abstract:: We construct the contact value approximation (CVA) for the pair distribution function, g(²)(r₁, r₂), for an inhomogeneous hard sphere fluid. The CVA is an average of two radial distribution functions, which each take as input the distance between the particles, |r₂ −r₁|, and the average value of the radial distribution...

Projected temperature and precipitation changes for Corvallis and Los Angeles for the 2030-2059 period using the Hadley Center's regional climate model (HadRM3P).

Creator:: Cheema, Karandeep Singh
Abstract:: Average monthly temperatures (maximum and minimum) and precipitation patterns are expected to change as a direct consequence of anthropogenic climate change. Temperatures are expected to be warmer in the future but precise estimates vary depending on factors like number of ensembles and emission scenario. For this study, we used 100...

Simulating Synchrotron Optical Flashes in the Reverse Shock of a Gamma Ray Burst

Creator:: Bice, Connor
Abstract:: We construct a Monte Carlo simulation in Python to calculate optical flashes at 5x10¹⁴ Hz peaking at 6x10³¹ erg s⁻¹Hz⁻¹St⁻¹ due to synchrotron radiation from the reverse shock of a gamma-ray burst’s jet. While analytical solutions to this problem exist, they rely on sweeping simplifications of what is necessarily a...

Organic Semiconductors : Incorporating Xylindein into (Opto)Electronic Devices

Creator:: Rath, Jeremy J.
Abstract:: This research investigates the electronic properties of a fungi-derived pigment, xylindein as a novel sustainable material for organic electronics. Xylindein molecules were characterized in solution and in film. Absorption spectra and (photo)luminescence spectra were taken at various excitation wavelengths. Xylindein’s molecular properties were computed with the Gaussian 09 software suite....

Solution method and error evolution of student responses to chain rule problems within a thermodynamics course

Creator:: Founds, Ian, W and Founds, Ian W.
Abstract:: Chain rules are critical to the process of solving many thermodynamics-related partial derivatives. This study evaluates the solution method and error evolution of students’ responses to a pair of chain rule problems in an upper-level undergraduate thermodynamics course. Students’ responses were categorized by solution method. Students’ solution methods included implicit...

Measuring Low Intensity Light Reflections of High Temperature CO₂ Adsorbed on SiO₂ Near Brewster's Angle

Creator:: Ferron, Thomas J.
Abstract:: This investigation expands on earlier methods of using surface polarization reflection (SPR) to characterize the first few monolayers of a surface. Past research measured intensities of light reflecting off an SiO₂ optical flat inside a vacuum. Pressure of applied gas was changed to view a change in reflection. In an...

Deriving relationships between number of observed short gamma ray bursts and viewing angle

Creator:: Micallef, John T.
Abstract:: Gamma ray bursts are some of the brightest events in the entire observable universe. Since the late 1960’s, thousands of gamma ray bursts have been observed and they have been researched extensively. However, there are still many mysteries which remain unsolved. One such mystery is whether or not the viewing...
