Remotely Controlled Enzyme Behavior Using Localized Thermal Gradients, Sarah Brown
Remotely Controlled Enzyme Behavior Using Localized Thermal Gradients, Sarah Brown
UNO Student Research and Creative Activity Fair
No existing model describes an identified special case of enzyme behavior when directly stimulated with thermal energy via an RF field.
The ability to remotely influence cellular functions and outcomes is a new approach to targeted medicine. Nano-medicine and biotechnology are the future of medical diagnostics and treatment. The ability to remotely influence cellular functions and outcomes is a new approach to targeted medicine. Direct heating of an enzyme vs bulk heating changes the enzyme activity.
I tested how direct transfer of thermal energy changes rates of enzyme reactions. We created samples of enzymes, attached to ferrous (magnetic) nano-particles, and …

Superpositioning High Power Lasers For Mid-Air Image Formation, Auston Viotto

Abstract
This research evaluates different methods to create voxels, 3-dimensional pixels, in air without the need for special glasses or reflections off of surfaces. Research on the advantages of superimposing or the culmination, focusing, of laser light will be conducted. The point of superpositioning/culmination will be evaluated by the brightness of the voxel due to the Rayleigh Scatter Effect. The voxel’s brightness is dependent on the laser output strength and inversely proportional to its wavelength. Once a superimposed/culminated voxel has been created in the lab the next step will be to manipulate the location of the voxel through 3-dimensional space. …

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
The Property Of Mass: An Interdisciplinary Metaphysical Investigation, Benjamin Hayworth
UNO 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
UNO 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
Between-Day Reliability Activity Fluctuations In Young Adults At Baseline And 6-Months Follow-Up, Connor J. Wicks
UNO 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. For …
