In Pursuit Of A Good Night’S Rest. Steps Towards Improving Electroencephalogram (Eeg) Accessibility And Affordability, Niyant Vora
In Pursuit Of A Good Night’S Rest. Steps Towards Improving Electroencephalogram (Eeg) Accessibility And Affordability, Niyant Vora
John Wesley Powell Student Research Conference
The Electroencephalogram (EEG), which is used to effectively record brain waves, has long been a key pillar of sleep research. However, sleep research has an important problem–the natural environment in which people sleep (their bedrooms), is not where sleep research is conducted. Several companies have released EEG headsets to try and address this problem, however, there are still many obstacles to home use. Such headsets are too expensive to be used by everyone and are still not effective enough to be utilized by physicians performing sleep studies. The goal of our research is to find affordable and innovative ways to …

Assembly, Alignment, And Maintenance Of An Automated Laser Cutter, Zhenghao Ding, Lunjun Liu, Gabriel C. Spalding, Faculty Advisor
Assembly, Alignment, And Maintenance Of An Automated Laser Cutter, Zhenghao Ding, Lunjun Liu, Gabriel C. Spalding, Faculty Advisor
John Wesley Powell Student Research Conference
We have assembled a kit for an automated laser cutter system, intended to play an important role in a wide variety of student-led design projects on our campus. We began by electrically soldering the wiring for a powerful (60 Watt), pulsed infrared (10.6µm wavelength) CO2 laser beam, which can thermally induce shock waves that locally ablate a wide range of (non-reflective) materials. The laser tube itself generates significant heat when operating, so we also assembled the required water-cooling system. Given the high powers involved, careful alignment this invisible laser was required, to ensure that the beam is safely contained …

A New Laboratory For Mm-/Sub-Mm-Wave Characterization Of Cosmic Dust Analogs, Lunjun Liu, Thushara Perera, Faculty Advisor
John Wesley Powell Student Research Conference
At visible wavelengths, cosmic dust obscures many interesting astronomical environments such as stellar nurseries and new planetary systems. Studying how light interacts with cosmic dust would help reveal the nature of the objects and environments that are obscured by dust. In order to study the optical properties of cosmic dust analogs in the lab, we constructed a custom apparatus, which consists of a vacuum chamber, a cooling mechanism to vary the temperature of dusts in an astronomically interesting range (7-50 Kelvin), and a long-wavelength spectrometer. Since completing the construction of the custom apparatus, we are currently assembling and testing the …

John Wesley Powell Student Research Conference
Known as the fundamental “lab on a chip” technology, microfluidics is a thriving young research area that first took off in the 1990s. It is commonly used for reducing the amount of material required for biochemical analysis, such DNA sequencing. Its narrow tunnels can annihilate turbulence even in high-speed fluid flow, facilitating controlled, systematic processing. Also, by leveraging lithographic techniques developed for the semiconductor industry, enormous capability can be integrated into a single microfluidic chip. We have thus far utilized templates designed and fabricated by previous students in our lab, for fabrication of a series of microfluidic chips, made of …
Contact Angle Measurement, Wenting Zhao, Mark Liffiton, Faculty Advisor
Contact Angle Measurement, Wenting Zhao, Mark Liffiton, Faculty Advisor
John Wesley Powell Student Research Conference
The Contact angle, where a liquid/vapor interface meets a solid surface[wiki], has been widely used to measure the wettability of a surface in physics and chemistry. Scientists place a drop on a surface of interest, take an image of the drop in profile, and measure the angle the drop makes with the surface. We have developed a Contact Angle Measurement plugin for the ImageJ image analysis framework, which provides researchers a easier way to access experiment data. The major goal of our algorithm is to automatically detect drops and surfaces via image analysis, so that we can calculate the contact …

Multidecompositions Of Complete Graphs Into A Graph Pair Of Order 6, Yizhe Gao, Mark Daniel Roberts, Faculty Advisor
John Wesley Powell Student Research Conference
A graph is a mathematical structure consisting of a set of objects called vertices and a set of 2-element subsets of vertices, called edges. The complete graph on n vertices is the graph with n vertices and an edge between any pair of distinct vertices. Let C6 denote the cycle on 6 vertices. We are interested in partitioning the edges of the complete graph on n vertices into copies of C6 and its complement with at least one copy of each graph. We provide necessary and sufficient conditions on n for the existence such a structure.
Quantification And Scavenging Ability Of Antioxidants In Bottled Tea, Jennifer Prochotsky, Manori Perera Faculty Advisor
Quantification And Scavenging Ability Of Antioxidants In Bottled Tea, Jennifer Prochotsky, Manori Perera Faculty Advisor
John Wesley Powell Student Research Conference
Bottled tea is made from brewed leaves of the Camelia sinensis plant. These leaves contain molecules called polyphenols that have aromatic rings with many alcohol groups. Different fermentation processes of the leaves lead to different types of tea, including black, oolong, green, and white tea. The polyphenols present in bottled tea have antioxidant properties, which have been seen to prevent certain types of diseases. Antioxidants work by stabilizing highly unstable free radicals, which are missing an electron in their orbital. Different studies have concluded contradictory results about which type of tea contains the highest quantity of antioxidants. There has been …

Detection And Quantification Of Lead And Copper In Firearm Harvested Ground Venison Intended For Human Consumption, Chris Crown, Manori Perera Faculty Advisor, Given Harper Faculty Advisor
John Wesley Powell Student Research Conference
Most White-tailed Deer (Odocoileus virginianus) in Illinois are harvested with firearms that use lead or copper shotgun slugs or muzzleloader bullets, which may fragment when they strike bone. Lead is a neurotoxin to both humans and animals that scavenge deer that have escaped from hunters, and excess amounts of copper ingestion can impair lipid and DNA function. In a preliminary study in 2014, packets of ground venison from firearm and bow hunters in Illinois were x-rayed, and six out of ten firearm-harvested packets contained possible metal fragments. The purpose of this study is to utilize Anodic Stripping Voltammetry …
