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...

Limit Equilibrium-Based Assessment of the Internal Stability of Geosynthetic Reinforced Soil Structures Subject to Seismicity

Creator:: Loving, Carly K.
Abstract:: Design of Geosynthetic-Reinforced Soil Structures (GRSS) require sufficient rear pullout anchoring capacity in order to maintain internal stability. Length requirements are amplified when reinforcement coverage ratios or seismicity is considered, potentially resulting in uneconomical GRSS design lengths. This study describes the influence of reinforcement length, coverage ratio, and pseudostatic seismic...

Chassis Design for the Global Formula Racing Team

Creator:: Powell, Zach L.
Abstract:: For the 2019 season, a new chassis layup was designed that is much stronger than in previous years, yet only slightly heavier. Compared to the baseline steel tube frame, the 2019 chassis has safety factors of about 110% for most zones. Also, a new impact attenuator was designed that absorbs...

Molecular Dynamics on REX-GECO1 Reveal Structural Features Governing Fluorescence

Creator:: Rozanov, Nikita
Abstract:: Fluorescent proteins have emerged as an essential toolset for bioimaging, creating a demand for engineering proteins with new and improved fluorescent properties. In this thesis, I explore the atomistic structure of REX-GECO1, a newly engineered protein biosensor that has unique optical properties. Since this protein has no available crystal structure,...

Analysis, design, and implementation of a Formula SAE cooling system

Creator:: Theroff, Zachary
Abstract:: This project consists of the analysis, design, and manufacturing of the 2016 cooling system for Global Formula Racing’s combustion vehicle. Several water configurations were examined, using computational fluid dynamics (CFD) to estimate airflow and heat transfer calculations in MATLAB to estimate heat rejection through each concept. Data used to perform...

Study of Organic Semiconductors Using Time-Resolved Charge Measurements at the Microscale

Creator:: Wallace, Richard
Abstract:: Understanding charge transfer in organic semiconductors is important for developing devices like organic light emitting diodes and flexible electronics. Optical tweezers have been used in many disciplines for trapping, manipulating, and analyzing microscopic objects such as microspheres, micro-organisms, and other colloidal particles. Using optical tweezers, studies have measured the average...

Introductory Physics 20X Comparative Study

Creator:: Frey, Brooke
Abstract:: The Introductory Physics 20X series has developed an advanced, metacognitive curriculum which requires a high degree of active learning in order for students to succeed in the class. Recently, the series has been transferred to the online campus, Ecampus, and is now available for distance learners. My work is focused...

Regulation by a developmental transcription factor of signaling enzymes related to atrial fibrillation

Creator:: Law, Christina M.
Abstract:: Atrial fibrillation is the most common cardiac arrhythmia, and the mechanisms that lead to this heart defect are not fully understood. Consequently, treatments for this defect do not currently reverse structural or molecular variations that lead to cardiac arrhythmia. Loss of the gene coding for the transcription factor Pitx2 leads...
