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 …
Enantioselective Biotransformation Of Prochiral Ketone Via Daucus Carota, Ryan Smith, Charlie Knox, Elizabeth Davis
Enantioselective Biotransformation Of Prochiral Ketone Via Daucus Carota, Ryan Smith, Charlie Knox, Elizabeth Davis
Undergraduate Research Conference
Biotransformations of prochiral ketones can be performed using plant cells. The benefits of using plant cells include low cost, environmentally sound procedures compared to conventional chemical processes, and the stereospecific nature of the reaction.1,2 Benzofuran-2-yl methyl ketone was reduced to (- )-benzofuran-2-yl-ethanol after incubation with carrots in water. The reaction was enantioselective in that it produced the S-isomer as indicated by optical activity. Currently, attempts to isolate the carrot enzyme and antimicrobial studies of the (-)-benzofuran-2-yl-ethanol product are underway.
Spectroscopic (Ir, Nmr, Uv-Vis), Theoretical Study And Optical Properties Of 9,10-Dihydrobenzo(A)Pyrene-7(8h)-One And 7, 8, 9, 10-Tetrahydrobenzo(A)Pyrene, Mireya Martinez
Undergraduate Research Conference
Polycyclic aromatic hydrocarbons (PAHs) are organic molecules found in the environment. The PAHs are formed from incomplete combustion, are found in diesel exhaust particles, grilled foods, gas burners, emission from wood, and cigarette smoke. These compounds are known to be carcinogenic and mutagenic1,2. Spectroscopic studies were performed on two PAHs, 9,10- dihydrobenzo(a) pyrene-7(8H)-one and 7,8,9,10- tetrahydrobenzo(a)pyrene, which helped to characterize them. Also, a theoretical infrared study was done on 9,10-H2BaP, a scaling factor was found for a simulated infrared spectrum.
Spectroscopic Studies Of Fluoranthene And 3-Nitrofluoranthene, Matthew Parks
Spectroscopic Studies Of Fluoranthene And 3-Nitrofluoranthene, Matthew Parks
Undergraduate Research Conference
Polycyclic aromatic hydrocarbons (PAHs) are known byproducts of anthropogenic sources including incomplete combustion of fossil fuels. They are known to be teratogenic, mutagenic and carcinogenic. This study investigated the spectral properties of fluoranthene and 3- nitrofluoranthene using NMR, UV-Vis and infrared techniques. The acquisition of spectral data provides a means to identify these compounds in mixtures and can be used which to develop model formulae for quantitation. A 2-D NMR method (HMQC ) was used for assigning 13C peaks. The infrared spectrum for 3-nitrofluoranthene showed characteristic strong absorption peaks at 1323 and 1516 cm-1 assigned to symmetric/asymmetric nitro stretches, respectively. …
