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...

Exploiting Diffraction Orders from a Phase Limited SLM to Remove and Model Zernike Aberrations

Creator:: Goschie, Aaron J.
Abstract:: Using a plastic bottle, we explore the capabilities of a reflective phase-only Spatial Light Modulator (SLM) in removing wavefront aberrations using a Zernike polynomial phase mask, with the modulators phase depth limited to 0.8π radians. Wavefront aberrations, which can be modeled with Zernike polynomials, distort image transmission through various optical...

Repair of a Scanning Tunneling Microscope and Retesting for the Formation of Pyramidal Structures Formed on Sputtered Germanium (110)

Creator:: Betz, Hazel R.
Abstract:: Semiconducting materials are of immense importance due to their presence in almost all modern devices. It is possible that the surface physics of semiconductors could be used to control the nanoscale topography and properties of these materials, ultimately creating new options for device fabrication. This could result in profound implications...

A Generalized Scheme for Creating Regge Calculus Models of General Relativity

Creator:: Hanson, Ben R.
Abstract:: Solutions to Einstein's equations are usually found by considering ideal, simplified models. However, if the real world always matched ideal physics models, then farmers would milk black and white spheres. To combat this, Regge calculus was developed as a numerical approximation scheme for general relativity. In Regge calculus curved manifolds...

Polarization Dependent Spectral Analysis Reveals Dipole Alignment and Intermolecular Coupling in Anthradithiophene Organic Semiconducting Crystals

Creator:: Lam, Andrew
Abstract:: Organic photovoltaics are being explored as the next generation material for semiconducting and optoelectronic devices but are limited by their stability and efficiency. One new candidate is crystallized Anthradithiophene (ADT), which is a promising photo-voltaic material due to its high quantum yield and adjustable side groups. The side derivatives TES-F,...

Riesz Transforms on a Sphere

Creator:: Tyma, Troy
Abstract:: Motivated by the Navier-Stokes equations, which are a set of unsolved equations related to fluid motion in R^3, we explored the incompressibility condition and the Neumann boundary problem. After exploring, we noticed that using iterated Riesz transforms of the boundary data could be used to get information about the velocity...

Simulating the Dynein Motor Protein: A Monte Carlo Approach to Achieve Coordinated Stepping

Creator:: Kiatvongcharoen, Jin
Abstract:: The motor protein dynein is responsible for cellular processes such as axonal transport and cell division by delivering vital information along the microtubule track. A failed delivery can cause severe damage to the cell’s functionality and lead to neurological diseases. Despite dynein’s rich history in cellular research, the mechanism of...

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...

Effect of Solar System Models on Pulsar Timing Experiments

Creator:: Nicolaysen, Cooper
Abstract:: Gravitational wave (GW) astronomy is a key ingredient in confirming Einstein’s theory of General Relativity and showing how the universe sends ripples through spacetime, distorting distances between two points. The confirmation of high-frequency GWs observed by The Laser Interferometer Gravitational-Wave Observatory (LIGO) in 2015 was a breakthrough in our understanding...
