Thermal Destabilization Of Azurin By Fatty Acid Ionic Liquids, Brandon Burrell, Austin K. Clark, Achismita Dutta, Esha Prajapati, Sierra Cottle, Andrew Ogungimi, Justin Burrell, Timothy D. Vaden

STEM Student Research Symposium Posters

Azurin is a mixed-structure redox protein involved in bacterial denitrification. Previous studies have shown that azurin is destabilized by imidazolium chloride ionic liquids (ImCl ILs) that can form micelles in aqueous solution, likely by micellar encapsulation. In these ImCl ILs the micelles form from the imidazolium cations. A relatively new class of ionic liquids is fatty acid ionic liquids (FAILs), in which the anion is a fatty acid. In FAILs micelles can form from the fatty acid anions. This presentation presents the results of a thermal unfolding study of azurin in the presence of FAILs in solution. The FAILs tetramethylguanidinium …

Commemorating Women Nobel Prize Laureates In Chemistry, Jordan Smith

Arkansas Women in STEM Conference

In this review study we describe contributions of women chemists who earned a Nobel Prize in Chemistry, notably the most prestigious award in the field. Based on our analysis of data, the number of women Nobel laureates in Chemistry is increasing with time. However, women still are the minority group compared to men in a pool of Nobel Prize winners in Chemistry.

In the current study we also compared women’s representation in chemistry to women’s representation in two other science fields of a Nobel Prize award: (i) Physics and (ii) Physiology or Medicine. Based on our analysis, the numbers of …

Comparing Computational Methods By Stretching Diatomic Molecules, Aaron Mitchell

Undergraduate Student Research Internships Conference

A comparison of functionals was done by comparing full electron density profiles along the bond axis of H₂ and N₂. Additionally, based on the success of the (HF)-DFT method, the goal of this project was to compare the mRKS method to (HF)-DFT.

Rearrangements Of Fluorinated Cyclopropylamines As A Novel Approach Toward Fluoroalkene-Based Peptidomimetics, Igor Mezentsev, Vera Zaborova

The International Student Science Fair 2018

Organofluorine molecules have been widely applied in various research fields because of the unique properties of fluorine atoms. One type of fluorinated compounds is fluoroalkene-based peptidomimetics which are structurally similar to amide-containing compounds. They have been prepared to improve the pharmaceutical properties such as bioactivity, target specificity, and metabolic stability of the bioactive amides.

We suggested a new way of synthesizing fluoroalkene-based peptidomimetics through 2-fluoro-2-halocyclopropylamines, which provides an effective way toward fluoroalkene-based peptidomimetics with increased functional group tolerance and possibility of convergent synthesis.

Feco2o4 As An Anode Material For Lithium Ion Batteries, Chelsea Wong

The International Student Science Fair 2018

Lithium ion batteries (LIBs) are commonly found in many portable electronic appliances due to their ability to be rechargeable. Currently, commercial anodes in Li-ion batteries (graphite) have a theoretical capacity of around 372 mAh/g, while FeCo2O4 that will be investigated as the anode material has a theoretical capacity of 901.985mAh/g, more than double of the current commercial anode’s capacity. Earlier work done by Sharma et al also showed that FeCo2O4 has a very promising initial capacity of 827mAh/g. As such, the engineering goal is to produce a battery that will have a higher capacity than the current commercial Li-ion batteries …

Removal Of Pb2+ Ions From Consuming Water Using A Fabricated Water Filter For Home Use, Pantaree Sodkhoksoong, Papidchaya Chanpong, Thunyarus Rodsawatchuchoke

The International Student Science Fair 2018

Lead contamination in water is one of the worldwide concerned environmental problems. For example, lead leaking from pipe corrosion and solder has been found contaminated in consuming water in many U.S. areas. The uncontrolled release of effluents containing lead from various industries has also caused lead-contaminated water in Thailand. Exposing to lead-contaminated water can lead to serious symptoms (e.g. fatigue, headaches, abdominal pain, irritability, depression, and seizures) or even death. Therefore, the elimination of lead ions (Pb²⁺) from consuming water or from effluents before releasing into the environment is necessary. The selection of adsorbents and the fabrication of …

Glucosamine From Hydrolysis Of 3d Printing Chitosan For Osteoarthritis Treatment, Ruj Dansriboon, Laphon Premcharoen

The International Student Science Fair 2018

This project aims to introduce a new way for osteoarthritis treatment which is expected to increase in the future. Glucosamine is the main subject for a treatment, which can be derived by hydrolyzing chitosan. This project also includes extraction of chitosan from shrimp waste to make a worthy use of food waste from industry. In this project, 3D printer is applied to print chitosan gel since 3D printing is adjustable to form various shapes of the gel.

The research process begins with the extraction of chitosan from shrimp shells. For the next step, the percent of deacetylation of chitosan was …

An Entirely New Molecular Glue For Mof Using Unusual Structural Transformation Of A Coordination Polymer, Sukwoo Jung, Hangyeol Kim, Junseok Ahn

The International Student Science Fair 2018

In this research, an entirely new molecular glue is reported. This ‘coordination polymer glue’ is synthesized from zinc metal and BDC-NPE(2,5-bis{4-[1-(4-nitrophenyl)ethylamino]butoxy}terephthalic acid). Molecular glue transforms from 1D coordination polymer to a 3D cross-linked framework, resulting in a phase change of solution to solid. The carboxylate group of this glue makes the preformed MOF bind to its framework. Therefore, when the solution of molecular glue is mixed with preformed MOF powder and heated, homogeneous and thin MOF film – MOF/ZnNPE film – is fabricated. The film is irrelevant to the kind of its substrate, and its thermal stability was enhanced in …

Session A-1: Bca Method, Focusing On Mole Ratios In Stoichiometry, Carmela Jones, Deb Scarano, Anita White

Professional Learning Day

Traditionally stoichiometry is done using dimensional analysis. Although effective, it is confusing, messy, and does not focus on mole ratios. On the other hand, the BCA method (Before-Change-After), is clear, clean, and highlights the mole ratios in a chemical reaction. Participants will collect mass data in an experiment and learn how to use a BCA table. Teachers will bring the BCA method back to their classrooms and provide an extremely useful tool for the next generation of chemistry savvy students.

Time Travel: Scientists And Their Contributions Towards The Discoveries Of The Atom And Atomic Properties, Austin Wright

GS4 Georgia Southern Student Scholars Symposium

The discovery of the atom and its associated components and properties paved the way for laying the foundation of chemistry related knowledge. However, the historical discoveries of each individual component are often forgotten or ignored due to the students‰Ûª innate belief of it ‰Û÷being difficult‰Ûª to remember such specific information. To assist students with grasping the properties of the atom and its components, a timeline-assisted chronology of atomic discoveries was created. Our objective is to present the scientists, with their individual contributions to atomic theory, along with the year it was discovered in an interactive manner. Using this timeline, students …

Isolation Of Antibacterial Compounds From Artemisia Californica, Jae Eun Min

Seaver College Research And Scholarly Achievement Symposium

The Chumash Native Americans of Southern California have well-documented traditions of using plants for medicinal purposes. If a specific plant has traditionally been used by Chumash for the treatment of cuts, wounds and infections, it may contain chemicals with anti-bacterial properties. One plant that fits these criteria is Artemisia californica (coastal sage). Because of the widespread use of antibiotics over the past sixty years bacteria are evolving greater resistance to known antibiotics, but unfortunately the rate of antibiotic discovery has diminished during the past twenty years. Therefore, novel and effective antibiotics are essential for the continued treatment of bacterial infections. …
