Biophysical techniques will be used to understand the behavior of biological macromolecules as they interact with these materials in the environment. Students will gain exposure to multidimensional NMR spectroscopy, spectroscopy, and separations, and they will gain the ability to interpret binding data using computational tools like MATLAB.
6. Characterization of gamma-ray imaging system for use in Depleted Uranium remediation efforts
Students engaged in this project will work with a gamma-ray imaging system to optimize techniques for identifying radioactive sources such as depleted uranium (DU) in the environment. DU, which is often found in the environment where it has been deployed by the US military, can be found in fragmented pieces covering large areas and in hard-to-access locations that contribute to radioactive contamination on the ground and in water supplies that poses dangers to human and wildlife health. Through developing various imaging modalities with a gamma-ray imaging system, identification and characterization of residual contamination can be achieved at large offset distances. Students will learn bench-top lab skills, data collection practices, spectroscopic analysis techniques, and software simulation validation as part of this project.

Students will work to scale up the production of engineered biochar, test batches of the production process, and install bioreactors in an agricultural setting for the removal of phosphorus from stormwater runoff. Students will learn bench-top lab skills, soil and water testing skills, and participate in field-scale deployment of materials for stormwater treatment.
8. Development of molecular materials for efficient energy harvesting and conversion
Students engaged with this project will identify and experimentally characterize new molecular materials that are suitable for high efficiency thermoelectric energy conversion. Single molecules are promising candidates for energy harvesting and conversion due the expected high efficiency. Developing molecular-scale energy harvesting technologies is crucial for adverting crisis in environment and energy. Students will learn bench-top lab skills and a range of characterization and analytical techniques used in the study of energy conversion at the molecular scale, including scanning tunneling microscopy, atomic force microscopy, optics, transmission electron microscopy, and scanning electron microscopy.

The goal of this work is to develop new approaches to the differentiation of closely related compounds (e.g., isomers), with relevance to the detection, characterization, and quantitation of pharmaceutical compounds in clinical and environmental analyses.
13. Water desalination and ion-removal by capacitive deionization
Removing salt ions from water is an energy-intensive process, but it is a critically important technology. The aim of this project is to find the most efficient, lowest-cost method to remove sodium, chloride, and fluoride ions from contaminated water. Capacitive deionization in combination with chemically modified bio-based electrodes is the approach used. Students will prepare chemically modified electrode materials, prepare desalination cells, and monitor the salt removal ability with ion-selective electrodes.
14. High Temperature Polyarylenes for Advanced Composites and Optoelectronic Applications
Polyarylene networks are produced via the thermal cyclopolymerization of bis-o-diynylarene (BODA) monomers affording intermediate resins which can be melt processed and thermally cured (Td > 400 °C). As a special class of enediynes, BODA monomers are prepared in three steps from commercial bis-phenols and undergo radical mediated Bergman cyclization and overall step-growth propagation to variable molecular weight reactive resin intermediates. Upon thermal processing via extrusion, infusion, coating, or micro/nano-molding and final cure, the resulting polyarylene networks are studied for applications such as thin film dielectrics, carbon fiber matrix composites, carbon-carbon composites, light emitting diodes, and photonic/electronic sensors. Students working on this project will learn standard synthetic organic techniques and characterization through IR and NMR.
15. Semi-Fluorinated Aromatic Ether Polymers for Optoelectronic and Energy Applications
Semi-fluorinated aromatic polymer are prepared via unique step-growth polymerization of fluoroalkenes.
Perfluorocyclobutyl (PFCB) aryl ether polymers are prepared via step-growth thermal cyclopolymerization of aryl trifluorovinyl ether (TFVE) monomers for a variety of applications desiring an optically tunable, thermally stable, and processable fluoropolymers. More recently, fluorinated aryl vinylene ether (FAVE) polymers are prepared from the condensation of functionalized bisphenols with TFVEs. In addition, perfluorocycloalkene (PFCA) polymers from commercial perfluorocycloalkene monomers and bisphenols are also under study. These three classes of fluoropolymers are solution processable, exhibit excellent thermal stability, and crosslink thermally without the use of post-curatives.
Students working on this project will learn standard synthetic organic techniques and characterization through IR and NMR.
16. Analysis of bottlenose dolphin (Tursiops truncatus) skin microbiome
The Mississippi Sound is home to the nation’s largest bay, sound, and estuarine population of common bottlenose dolphins (Tursiops truncates), serving as a nursery ground for newborn dolphin calves and providing vital foraging habitat for dolphins. Dolphin skin has a microbiome that serves in a protective role for healthy dolphins, but it can also harbor opportunistic pathogens that can cause disease if dolphins become stressed or their skin is compromised. Because dolphins are in intimate contact with their marine environment, their skin microbiome is heavily influenced by water conditions. To protect and maintain the health of this important population, information is needed about the microbiome of dolphin skin. In this project, the student will work with a team to use high-throughput DNA sequencing and computer analysis to characterize the microbiome on skin of dolphins from the Mississippi Sound.
