The Environmental Protection Agency (EPA) guidelines state that lead is a toxic metal that humans should not be exposed to in any amount. Due to corrosion of water pipes, lead can enter drinking water and be consumed by millions of people. As a group, we decided to reduce this issue by creating a simple and inexpensive paper-based test to detect lead(II) in water. The signal for this test results from encapsulating a phenanthroline-based probe in synthesized polymer nanoparticles. This test will display a colorimetric change, turning from yellow to bright orange if lead(II) is present in the water system. In …
Synthesis And Characterization Of Oxovanadium Compounds As Potential Insulin Mimetic Molecules, Kaitlyn Mercando, Jeffrey A. Rood
Synthesis And Characterization Of Oxovanadium Compounds As Potential Insulin Mimetic Molecules, Kaitlyn Mercando, Jeffrey A. Rood

Oxovanadium(IV) complexes have numerous applications in diverse areas such as catalysts for organic transformations and as anti-fungal agents. Complexes that this research focused on have shown potential in acting as insulin mimetics. The goal of this research was to synthesis and fully characterize a new series of oxovanadium complexes and then investigate the insulin mimetic properties of the complexes with adipose cell culture work. Vanadyl complexes involving a series of salicylaldiminato ligands [C6H5N=CHC6H4OH (L1), 2,6-iPrC6H3N=CHC6H4OH (L2), C6H5N=CH-3,5-tBu2C6H2OH (L3) and 2,6-iPrC6H3N=CH-3,5-tBu2C6H2OH (L4)] were synthesized and structurally characterized. The ligand set was investigated due to the ease of sterically tuning the substituents …

Metal-Organic Frameworks (MOFs) are materials that contain metal centers coordinated by organic molecules that form an extended, porous lattice. These MOFs are of interest in the field of sensing for their unique properties such as high stability, high surface area, high crystallinity, and ability to perform small molecule exchange. Luminescent metal-organic frameworks (LMOFs) are of specific interest since they contain the potential to detect odorless volatile organic compounds (VOCs) via adsorption into the porous framework. Luminescent properties can be imparted to MOFs in several ways. This project focused on the inclusion of a luminescent osmium complex into the MOF scaffold. …
