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...

Monte Carlo Simulations for a Soft Sphere Fluid

Creator:: Kreitzberg, Patrick
Abstract:: In this paper I present the results of Monte Carlo simulations for a soft sphere fluid with a Weeks-Chandler-Anderson (WCA) pair potential. The results are compared to Soft Fundamental Measure Theory (SFMT) results obtained by our research group. One of the research group’s goals was to show that our SFMT...

Calculating characteristic timescales for environmental decoherence in the presence of thermal gravitons

Creator:: Nelson, Hunter
Abstract:: Different models show the effects of environmental decoherence on a quantum system due to various environments of interest. One important quantity within these models is the decoherence time, which tells us how quickly environments wash away the coherence of local measurements. We can describe this effect as the quantum system...

Design of an Optical Medium for the Simulation of Neutron Transport in Reactor Component Materials

Creator:: Konyndyk, David M.
Abstract:: The scattering of optical rays by small spherical particles bears a strong resemblance to the diffusion of fission neutrons in solid materials. This work explores the feasibility of exploiting similarities between these two systems for the purposes of reactor component analysis, education, and outreach. After a brief overview of reactor-environment...

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...

Freezing a Softly Repulsive Fluid : Monte Carlo Methods and the Weeks-Chandler-Andersen Potential

Creator:: May, Christopher
Abstract:: The equation of state for a fluid described by the Weeks-Chandler-Andersen (WCA) potential was solved to determine at what pressures and temperatures the fluid will theoretically freeze. A Monte Carlo (MC) algorithm was used to sample a system of 256 spheres for a set of thermodynamic averages to locate and...

Practical Mechanically Interlocked Molecules: A Model of Gas Adsorption in Metal OrganicFrameworks Harboring Rotaxane Molecular Shuttles

Creator:: Carney, Jonathan
Abstract:: Metal organic frameworks(MOFs) are a class of crystalline materials utilized in gas storage, chemicalsensing, and other engineering applications. Recently chemists have begun synthesizing MOFs withmoving parts in order to further these applications. A wide array of dynamic MOFs have been created andtheorized. Among them is the interlocking of a ring...

The interaction of bulk heterojunction donor/acceptor blends with polaritonic state creation in organic crystalline films

Creator:: Center, Reid
Abstract:: We explore the interactions between charge transfer exciton states (CTEs) and an optical microcavity by testing the effects that cavity resonance has on the CTEs and if CTEs can be coupled with a photon to create quasiparticles known as polaritons. Exciton polaritonics is becoming a booming area of research mainly...

Optical Tweezer Trapping of Colloidal Polystyrene and Silica Microspheres

Creator:: Peters, Kyle C.
Abstract:: Optical trapping is a tool used throughout a wide variety of disciplines rang- ing from precisely probing and manipulating sub-micron organisms in biol- ogy to analyzing fundamental charge transfer in colloidal physics. This thesis presents research involving optical tweezer force measurements of polystyrene and silica microspheres. In addition, preliminary work...
