Hear from Young Scientists at Sigma Xi's 2014 International Research Conference

Ten students were selected to be interviewed about the research projects they presented at the 2014 Sigma Xi International Research Conference. The students were placed in divisions including high school, undergraduate, or graduate. The categories were multidisciplinary, ranging from astronomy, chemistry, engineering, physiology, and many others. Learn more from the students who were interviewed in their audio interviews, abstracts, and other general information below:

If interviewees have a medal icon next to their name, they were ranked as a superior presenter.

"A fuel cell is a device that converts hydrogen/hydrocarbon into electrical energy. And the goal of my research was to increase the performance of the fuel cell by coating with metals that could increase the conductivity of electrons."

Engineering (Poster Abstract ENG-06): "Fabrication and Characterization of Metal-Patterned SrCo0.9Nb0.1O3-δ Thin Film Cathodes with Well-Defined Geometry."

"My research is about studying the feasibility of using dipiverfrin, a prodrug of epinephrine, for sublingual administration of first aid treatment of anaphylaxis. Anaphylaxis is actually a series of reactions, hypersensitivity reactions, that occurs once the person is re-exposed to certain antigens.

"I was examining the influence that genes might have on physical stress in American Samoans. So I looked at if people who had certain versions of genes were at risk for higher physical stress...And then next I looked at associations between that and age, sex, and education to try to determine other associations."

"The goal is to get a better idea of how many stars end their lives as supernovae, or carbon-oxygen white dwarfs, or neon white dwarfs, which would basically have different properties once they end their lives in what we see in everyday observational astronomy."

"I study how nitrogen-fixing bacteria affect plant defense, specifically how one mutualism, or beneficial relationship between two organisms, affects another mutualism. The other mutualism that is in this plant is a plant-defense mutualism. That is where plants will attract ants using something call extrafloral nectar...not for the sake of pollination, instead to attract plant 'bodyguards.' So aggressive behavior from ants helps the plants survive because they protect them from herbivores, or consumers."

"My research topic is about orthopedic biomechanics, so I investigated the way to increase fixation strength for long bone fractures...One of the ways is to use a system of plate and screw to fixate the long bone. My method study is to study the angle configuration, so changing the mechanic which in turn changing the geometry of the screw. And then I study the effects of changing that mechanics—will it have an effect on the fixation system as a whole?"

"This is about the people who are trying to learn English and find out between American, Australian, and British accent, which accent is the easiest for them to adapt and learn, and their attitude towards the accent. When they have a positive attitude, it brings them motivation, and when they have the motivation it makes it much faster and easier for them to learn the new language."

"My project involves the identification and characterization of the Actr2 gene in the modification of thrombosis susceptibility. And the reason that we are trying to do this is so we can gain a better understanding of the events leading to and from thrombosis in an effort to potentially derive novel therapeutic strategies or targets."

"Algae is a green plant-like organism growing in the water... Basically you can grow algae in wastewater sources, and they utilize excess carbon sources in the air. So by growing algae in the wastewater sources you can get some environmental benefits and also get an energy source. Particularly I am working on macroalgae, which is bigger algae than the small, microalgae. Unlike microalgae, there's less energy cost in harvesting the bigger biomass, and the watering cost is smaller for the macroalgae, as well."

"We built a smartphone application to measure shoulder and elbow range of motion. Range of motion is important in orthopedics and in clinical settings because that's what really determines your diagnosis and your functionality so getting an accurate and quick way of measuring range of motion is extremely important."
