Bandgap measurements of nonspecular materials using a bifurcated fiber optic method of diffuse reflectance

Creator:: Wells, Blake
Abstract:: A method for determining bandgap energy using diffuse reflection is presented. The method uses bifurcated fiber optic cables to measure the diffuse reflection of diffusely reflective materials. The absorption spectrum is extrapolated from the diffuse reflection spectrum and used to determine the bandgap of powdered materials. The theory of nonspecular...

The Formation of Astrophysical Dust

Creator:: Mauney, Christopher M.
Abstract:: The formation of carbonaceous and silicate precursor molecules to astrophysical dust grains is investigated. Using density functional theory (DFT) in combination with global optimization techniques, the ground-state binding energies of dust precursors are determined. These results are employed in atomistic nucleation theory (ANT) to predict the critical size and nucleation...

Perturbed directional correlation in Ta-181

Creator:: Sommerfeldt, Raymond Walter
Abstract:: The effect of a static quadrupole interaction on the 133-482 Kev gamma-gamma angular correlation in Ta-181 has been studied by the delayed coincidence method. Using a source of Hf-181 in polycrystalline hafnium metal, the anisotropy was measured as a function of time between the formation and decay of the 482...

Generation and manipulation of THz waves

Creator:: Amer, Naaman
Abstract:: In this thesis I studied several THz components that can be used for potential THz technology. THz waves were generated in nonlinear medium via optical rectification of femtosecond optical pulses. Utilizing the phase matching condition between the optical and THz waves in a ZnTe crystal, single-cycle broad-band THz pulses were...

Simulating dynein’s powerstroke using Brownian dynamics

Creator:: Capek, Elliott L.
Abstract:: Dynein is a motor protein which transports cargo along tracks inside the cell. Like related motor proteins kinesin and myosin, dynein uses cellular energy to take steps with its two foot domains. Unlike kinesin or myosin, dynein’s stepping pattern is highly varied: it can take steps between zero and 60nm...
