Organic Chemistry Through Dance, Holly Gibson
Organic Chemistry Through Dance, Holly Gibson
Undergraduate Research Conference
This research project explores representing organic chemistry mechanisms using dance. Dancers represent molecules, electrons, and atoms in demonstrating the movement of electrons and bonds created and broken by the movement. It was concluded that some organic mechanisms and ideas can be easily transferred to a dance concept, while others take more time and exploration. Additionally, dancers representing the atoms and electrons were able to have a better grasp of what was occurring, regardless of chemical education background. This leads to the conclusion of a new way to implement kinesthetic learning into the chemistry classroom. The purpose of the videos are …
Bomb Calorimetry: A New Method Of Cec Determination, Trace Washburn
Bomb Calorimetry: A New Method Of Cec Determination, Trace Washburn
Undergraduate Research Conference
A new method of determining the cation exchange capacity (CEC) of clay minerals was examined. This method involved exchanging the smectite clay with organic cations and using bomb calorimetry to measure the energy of combustion of the material. Because the clay is noncombustible, the energy is completely dependent on the amount of organic present, which is dependent on the CEC of the clay. Two organic cations, tetrapentylammonium and octadecyltrimethylammonium , with similar size but much different shape were used. For clays with lower CECs, using the more symmetric ion yielded better accuracy (4.24%), while for clays with higher CEC, using …

Antimicrobial Properties Of Isomers Of Benzofuranylethanol, Nick Cheatwood, Jessica Bronstad, Michele Harris
Undergraduate Research Conference
A biotransformaDon reacDon is a chemical conversion of a substance into a desired product with the aid of whole, living cells containing the necessary enzymes. In addiDons to living cells, other substances, such as vegetable strips, will also catalyze biotransformaDon reacDons. Advantages of biotransformaDon reacDons include the following: the ability to recycle material, the use of less hazardous chemicals, the ability to compost vegetable strips, the use of inexpensive materials that are locally available, and the ability to produce a single isomer. The biotransformaDon reacDon for the conversion of benzofuranyl methyl ketone (BMK) to (-)-benzofuranylethanol (BMA) using carrot strips as …
Water Soluble Cationic Porphyrin Sensor For Detection Of Hg2+, Pb2+, Cd2+, And Cu2+, Christopher Orr, Miranda Uherek, Matibur Zamadar
Water Soluble Cationic Porphyrin Sensor For Detection Of Hg2+, Pb2+, Cd2+, And Cu2+, Christopher Orr, Miranda Uherek, Matibur Zamadar
Undergraduate Research Conference
Here we report the sensing properties of the aqueous solution of mesotetra(N-methyl-4-pyridyl)porphine tetrachloride (1) for simultaneous detection of toxic metal ions by using UV-vis spectroscopy. Cationic porphyrin 1 displayed different electronic absorptions in UV-vis region upon interacting with Hg2+, Pb2+, Cd2+, and Cu2+ ions in neutral water solution at room temperature. Quite interestingly, the porphyrin 1 showed that it can function as a single optical chemical sensor and/ or metal ion receptor capable of detecting two or more toxic metal ions, particularly, Hg2+, Pb2+, and Cd2+ ions coexisting in a water sample. Porphyrin 1 in an aqueous solution provides a …

Determination Of Anions In Lanana Creek By Ion Chromatography, Tania Benavides
Determination Of Anions In Lanana Creek By Ion Chromatography, Tania Benavides
Undergraduate Research Conference
Abstract
Lanana Creek is one of two springs that surround Nacogdoches, TX. Lanana Creek starts southwest of Lake Naconiche, conjoining with several other bodies of water along its path, and becomes part of the Angelina River. This body of water eventually ends in the Gulf of Mexico which may contribute to the dead zone. Contaminants in water may be of small concentration; however, prolonged exposure could produce many negative effects. To prevent further contamination, the source of the contamination must be identified through testing the water for contaminants. Some possible sources of contamination may be from fertilizers and pesticides used …
