Designing Novel Nanostructured Permanent Magnets, Ali Al Kadhim Mar 2017

Designing Novel Nanostructured Permanent Magnets, Ali Al Kadhim

Student Research and Creative Activity Fair

Rare earth element based alloys have been the source of high performance magnetic alloys, and have played a paramount role in the development of various technologies, including: memory devices (such as credit cards, random-access memory), sensors, and various biomedical applications. However, there is a tremendous need to replace rare earth metals with material with powerful magnetic properties. Our group recently found CrTe-based materials that show very promising magnetic properties in nanostructured form. The magnetic modeling of such material in nanostructured form prior to their fabrication demonstrates their magnetic properties in bulk form. In this project, we investigate the behavior of ...


The Property Of Mass: An Interdisciplinary Metaphysical Investigation, Benjamin Hayworth Mar 2017

The Property Of Mass: An Interdisciplinary Metaphysical Investigation, Benjamin Hayworth

Student Research and Creative Activity Fair

The property of mass as used in the physical sciences is somewhat of a metaphysical conundrum. Not only has the definition of mass changed with various paradigm shifts in physics, but the powers belonging to the property have also varied. In my study, I begin by examining the historical context surrounding the term, including the changes to its definition. In doing so, it is revealed that various definitions of mass are used and circulated in general discussion, so a cogent criterion of identity is established by which each definition can be measured. After determining the distinctions between each mass term ...


Improving Sers-Based Readout Strategy For Biomarker Detecting Immunoassays, Joseph Smolsky Mar 2017

Improving Sers-Based Readout Strategy For Biomarker Detecting Immunoassays, Joseph Smolsky

Student Research and Creative Activity Fair

Detection and monitoring of disease biomarkers increases probability of successful disease treatment. Surface enhanced Raman scattering (SERS) has several advantages over conventional readout strategies utilized in detecting immunoassays. SERS provides a method for chemical characterization based on molecular vibrational spectra. Raman signals are typically weak and need to be enhanced. This can be done using plasmons in nanoparticles of noble metals, we use gold (Au). Molecules with known spectra, Raman reporter molecules (RRM), can be adsorbed to Au nanoparticles. This enhances the Raman signal of the RRM when illuminated by a laser of optimal wavelength. Adding antibodies to nanoparticles modified ...


Between-Day Reliability Activity Fluctuations In Young Adults At Baseline And 6-Months Follow-Up, Connor J. Wicks Mar 2017

Between-Day Reliability Activity Fluctuations In Young Adults At Baseline And 6-Months Follow-Up, Connor J. Wicks

Student Research and Creative Activity Fair

Human Daily Motor Activity (DMA) is characterized by complex temporal fluctuations and scale invariance. DMA is estimated from a time series composed of continuous amounts of activity recorded with the Actigraph GT9X monitor. The purpose of this study was to measure the complex temporal fluctuations in several young healthy adults over a 7-day period. After six months there was a follow-up of another 7-day period. Future collections will involve healthy older adults and adults with Parkinson’s disease. For the first phase of this study, 24 healthy young adults wore the monitor on their non-dominant hand for seven straight days ...
