Programs & Awards  
2008 Sigma Pi Sigma Undergraduate Research Awards

Sigma Pi Sigma, the national physics honor societyThe following six Society of Physics Students (SPS) chapters have received Sigma Pi Sigma Undergraduate Research Awards to fund chapter research projects. The awards provide calendar year grants to support local chapter activities that are deemed imaginative and likely to contribute to the strengthening of the SPS program. The program is funded through income from the Sigma Pi Sigma Trust Endowment Fund.
Recipients: 2013 | 2012 | 2011 | 2010 | 2009 | 2008 | 2007 | 2006 | 2005 | 2004 | 2003 | 2002 | 2001 & Previous

Investigation of Viscosity Transitions in Non-Newtonian Fluids

Interim Project Report | Final Project Report

Abstract
We will build a sensitive variable-speed coaxial-cylinder viscometer, then use the viscometer to characterize the transition between liquid and solid behavior or dilatant non-Newtonian fluids. Previous work in this department has indicated that the transition has interesting "discontinuous" characteristics not predicted by simple descriptions of dilatant fluids.

Ferroelectric Nanoparticles Suspended in Liquid Crystals

Interim Project Report | Final Project Report

Abstract
From wristwatches to the most advanced computer systems on earth, liquid crystals have made their way into every aspect of our lives. Since liquid crystals have been introduced to the industry there has been a great demand to reduce their energy consumption. That is the great problem, making a stable liquid crystal display that uses less energy. There is a possible solution, mixing liquid crystals with material that posses a higher sensitivity to electric fields. There are preliminary results which suggest the feasibility of creating such materials.

Although this solution may sound simple, there are major problems that need to be overcome in order to make this not only "a lab sample," but a practical reality. Through the support of the SPS and the use of the UCSS Liquid Crystal Research Lab, we look forward to becoming engaged in this project. Particularly, by creating a stable "liquid crystal enriched with ferroelectric nanoparticles" we will have successfully lowered the energy consumption of all liquid crystal devices. This would not only mean longer battery life for cell phones and laptops, it would mean a great leap in the science of liquid crystals and a new frontier in the industry.

Binary Orbital Motion of Electrically Charged Spheres

Interim Project Report | Final Project Report

Abstract
Coulomb's Law of Electrostatics and Newton's Law of Gravitation suggest that two oppositely charged spheres should be able to move in binary orbit about their center of mass using only the electric force as the force of attraction. The Rhodes College Chapter of SPS will attempt to achieve a binary orbit between oppositely charged graphite coated styrofoam spheres in a near-zero gravity environment as part of NASA's Microgravity University.

Investigating the Effects of Atmospheric Composition on Sound Emitted by a Telsa Coil Speaker

Interim Project Report | Final Project Report

Abstract
Plasma speakers (a.k.a. tesla coil speakers) have gained popularity over the past few years, but little scientific work has been performed on them as most are built by hobbyists. The USU Chapter of the Society of Physics Students will build a small tesla coil modeled after the coronaphone developed at Villanova University. Chapter members will record the sound propagating through four gases: Nitrogen (N2), Carbon Dioxide (CO2), and Argon (Ar). These spectra will be compared with one another and with data taken in air, to see if changes in sonic spectra refl ect properties of the gases.

Scanning Probe Study of Viral Nanowire

Interim Project Report | Final Project Report

Abstract
Viruses that coat themselves in selected inorganic substances can self-assemble into various devices including nanowires. We propose a Scanning Tunneling Microscope study of the electronic structure of such an array of nanowires formed by coating gold nanoparticles on M13 virus.

Variable Star Observation and Search

Interim Project Report | Final Project Report

Abstract
The purpose of this project is to locate, observe, and classify variable stars.  Variable stars are stars that vary in their light output.  The Drexel SPS chapter will use the observatory facility on campus, as well as supplies purchased with the grant money, to observe and collect data on these stars.

Developing Reduced Noise Electronics for a Gigahertz Radio Telescope and Implementing a Real Time Web Interface

Abstract
There exists, at Oregon State University, a continuing undergraduate research project which is attempting to construct and operate a radio telescope. The proposed research program will improve this telescope to scientific standards and integrate it with a web interface, which would allow students and the public to view the status of the telescope in real time.

Ground Effect Vehicles: Exploring the Possibilities of Wing Design to Maximize Vehicle Lift

Interim Project Report | Final Project Report

Abstract
We will identify the characteristics that maximize the efficiency of ground effect aircraft. We will explore the effects of airfoil shape, wing classification, and wing planform design on aircraft lift. We will then produce a model that combines the most favorable wing characteristics in order to maximize vehicle lift.
