Evaluating Our Reliance On Rare Earth Minerals And Platinum Group Metals Over The Period Of 2012 To 2021, Ryan Smith

Spring Showcase for Research and Creative Inquiry

Rare Earth Elements (REE’s) are minerals used in our everyday lives. They can be found in our household appliances, phones, computers, cars, as part of wind turbines and solar panels. The US relies on imports of these rare earths from several other countries (e.g. China, Estonia, Malaysia, and Japan) as we cannot mine a majority of the minerals (e.g. cerium, lanthanum, europium, etc) domestically. Since the year 2012, the US has imported approximately 3,000 metric tons of rare earths, and in recent years, this number significantly increased. As of 2021, the US now imports approximately 43,000 metric tons of rare …

P-39 Interdisciplinary Diffusion Lab, Sable Canales, Chloe Gaban, Mickey Kutzner

Celebration of Research and Creative Scholarship

Diffusion is a principle in Physics, Chemistry, and Biology. The rate of diffusion is affected by temperature, particle size, concentration, and material type. Students can model the rate of diffusion based on particle size by contrasting blue and yellow dyes. Two petri dishes containing agar-agar receive a drop of dye at the center. The radius of expansion is recorded over time. The variance of the distribution grows as 𝜎2=4𝐷𝑡, where 𝜎2 is the variance, D is the diffusion constant, and t is time. Graphing variance versus time gives a slope of 4D. Diffusion constants vary by particle size, allowing for …

Determination Of Nitrate In Aqueous Media, Ebony Arauz Tellez, John Bohannon, Rebecca Mills, Virginia Tam, Isabelle Villarreal, Melissa C. Rhoten

Spring Showcase for Research and Creative Inquiry

Determining the amount of inorganic ions in aqueous media is important in the food industry and environmentally. In the environment high levels of ions like nitrate (NO₃^-), nitrite (NO2^-), and phosphate (PO₄^3-) can lead to unhealthy conditions for aquatic species. Similarly, high levels of nitrate and nitrite can cause health issues in humans. One method for determining nitrate levels in aqueous samples involves reducing the nitrate species to nitrite via a redox reaction with finely divided zinc powder followed by conversion to a diazonium salt and complexation with 1-napthylamine to form a …

Is It Useful? Orthophosphate Mapping Of An Excavated Cellar Of A Mid 1700’S Tavern In New London Va, Thomas M. Bender, Randy Lichtenberger

Faculty Publications and Presentations

The partially backfilled cellar of Mead’s Tavern (VDHR # 015-0120) a circa 1760’s building in New London Virginia, was studied by orthophosphate (PO₄³) mapping of the recently exposed, culturally sterile, subsoil floor. Prior studies of the cellar had exposed a hearth along with features that were speculated to be wall partitions for subdivision of the cellar. The full intended purpose for those exposed features is unknown. To further probe that exposed subsoil prior to a major engineering stabilization of the tavern’s foundation, a chemical mapping of surface PO₄^3- levels in the cellar was done. The …

Fluid Inclusion Analysis Of Halite: A Snapshot Of The Cambrian Explosion, Amy R.A. Lefebvre

With the help of halite screening methods, fluid and gas analysis, through a micro thermometer and mass spectrometer, respectively, as well as trace element analysis conducted by Act Labs, results reflecting Earth's climate over 500 million years ago were obtained. These indicated the approximate weather conditions, and atmospheric composition, during this time period, within an intracontinental dessert location. Specifically, these results reflects a global warming period, with daily variations. Although much more research is needed in order to validate this summer's …

Uncovering The Mysteries Of Retention Ponds: Comparing The Abundance And Type Of Microplastics In Storm Water Ponds In London Ontario, Natalie Rose Minda

Undergraduate Student Research Internships Conference

Microplastics are plastics <5 mm (Liu, 2019; Arthur et al., 2009). They are created in two ways: Intentionally or from the fragmentation of larger pieces of plastic (National Ocean Service, 2021). They can negatively impact human, wildlife and ecosystem health in many ways depending on the exposure, type, size, and shape of the microplastic (Campanale, 2020). Retention ponds are often created in neighborhoods to collect water in order to prevent flooding. They also often serve as habitat for wildlife. Sediment samples were collected in two ponds in London Ontario both dredged in 2016. Samples were processed in the lab and further analyzed under the microscope to isolate the microplastics. Results have not been determined yet, but the abundance and type of microplastic varies in both ponds. Plastic pollution in retention ponds should be considered more, as it poses a threat to human and ecosystem health.

Using Stable-Isotopes To Determine The Effects Of Land-Use Change On Carbon Storage, Morgan Basile

Undergraduate Student Research Internships Conference

Over the last century, there has been drastic conversion of natural vegetation to agriculture. The decomposition of plant tissue is transformed into soil organic matter that is rich in carbon and stored within soil aggregates. This research examines the effects of land-use change on carbon storage by using stable-isotopes of organic matter. The stable-isotopes of organic matter within aggregates will be used to quantify the amount of carbon that has been added to the soil after a change in land-use (e.g. restoration of agricultural land to grassland).

Meteorite Investigation And Classification, Olivia N. Benest

Undergraduate Student Research Internships Conference

Several meteorites arrive on Earth every day, but only a small percentage of them are found. They are easiest to spot on deserts or frozen ice. Western has a large number of unclassified meteorites found in the Northwest Africa (NWA) and Oman deserts. These meteorites include chondrites, achondrites, irons, and even Lunar and Martian meteorites. Classifying a meteorite requires detailed examination by optical microscopy, as well as micro X-ray diffraction (µXRD), and Electron Probe Microanalysis (EPMA), to observe their mineralogy (metal, oxide, sulfide, and silicate mineral phases), textures (e.g. chondrules, CAIs) and composition, in order to classify their petrologic type …

Development Of High-Resolution Meteor Spectra Analysis, Zhangqing Yang

Undergraduate Student Research Internships Conference

Meteoroids are often billions of years old and as they ablate and ionize in the atmosphere, they give off light leaving us clues to the history of our solar system. In addition, their presence imposes serious risks to our equipment and astronauts in space. My research deals with analyzing High-Resolution Meteor Spectra, which are obtained by separating the light Meteors give off through a Diffraction Grating. Firstly, as the Meteor’s speed during ablation affects its spectrum, the position, speed, and trajectory of 40 well-tracked Meteors (picked from over 500) were determined using the programs Metal and Mirfit. Then, the spectra …

Simulating Salience: Developing A Model Of Choice In The Visual Coordination Game, Adib Sedig

Undergraduate Student Research Internships Conference

This project is primarily inspired by three papers: Colin Camerer and Xiaomin Li’s (2019 working paper)—Using Visual Salience in Empirical Game Theory, Ryan Oprea’s (2020)—What Makes a Rule Complex?, and Caplin et. al.’s (2011)—Search and Satisficing. Over the summer, I worked towards constructing a model of choice for the visual coordination game that can model player behavior more accurately than traditional game theoretic predictions. It attempts to do so by incorporating a degree of bias towards salience into a cellular automaton search algorithm and utilizing it alongside a sequential search mechanism of satisficing. This …

Corrosion Prevention Of Aluminum Alloy, Andrea Brenner

Symposium of Student Scholars

Aluminum alloy (Al-alloy) is a widely used metal in construction, aerospace, aviation, and other necessary fields due to its lightweight and tweakable properties. However, corrosion is inevitable on metals and alloys, and that causes millions of dollars of revenue loss every year. Therefore, we propose to research fabricating coating to prevent corrosion on Al-alloy. This study uses an iron-based metal-organic framework (MOF) and polyurethane (PU) based composite coating to prevent corrosion on the Al-alloy. The makeup of the composite material is changed by varying the percentage of MOF. In addition, a binder is also used to enhance the homogenization between …

Rotoscoping Image Processing, David J. Blackstone

Student Scholar Showcase

I wrote a program to perform rotoscoping image processing. Rotoscoping is an animation technique that is used to turn real images into cartoon images. This is a lengthy process to do by hand, taking hundreds of hours. To make this job easier, I have written a program to do automated rotoscoping. This program uses many algorithms and techniques such as edge detection, blurring, directional detection, and edge tracking. What once would take hours by hand, takes seconds!

Mapping The Impact Of A Trailway System On The Amount Of Trash Present Within Two Watersheds Of Lynchburg City, Virginia, Lillian Smith

Student Scholar Showcase

Transportation of trash debris within water systems is a prominent occurrence which has been linked to natural and artificial processes such as wind, rain, and littering. Recreational areas, such as activities along greenway trails, have been determined to be a source of debris found in waterways. This study examines whether the presence of an established recreational trail system limits trash accumulation in the entirety of a watershed. Trash data collected at Blackwater Creek, which contains an established trail system, was compared to trash data collected at Fishing Creek, containing a non-established trail system, to answer this hypothesis. A distance of …
