Tunable Copper Complexes For Sustainable Photocatalysis, David Kline
Photoredox catalysis has direct applications in sustainable chemistry and thus an immense impact on our environment. With the ability to harness energy directly from the sun to catalyze useful chemical reactions, photocatalysts can help to eliminate the need for harsh reaction conditions and reduce generation of hazardous chemical waste. Photocatalysts based on Earth-abundant metals such as copper have recently emerged as sustainable alternatives to rare-earth metals including iridium and ruthenium, which are no longer required for many photocatalyzed chemical transformations.

Spectrofluorometric Analysis of Bisphenol-A in Drinking Water Bottles
Bisphenol-A (BPA) is of environmental concern due to its ability to act as an endocrine disruptor in humans and many other animals. In the food industry, BPA is widely used in the production of plastic bottles and plastic liners in aluminum cans. Over time, trace amounts of BPA can leach from the container and into the contents inside. A new method of testing for trace amount of BPA involved the formation of an inclusion complex with ß-Cyclodextrin. With the formation of the inclusion complex, it becomes much easier to analyze low concentrations ...
Energy Densification Via Hydrothermal Carbonization, Keri Noack
Festival of Communities: UG Symposium (Posters)
A process called hydrothermal carbonization (HTC), also known as wet torrefaction involves treatment of raw biomass in hot, pressurized water. HTC of woody biomass has been shown to significantly increase the energy density of the feedstock, producing a biochar, similar to coal, having up to 40% higher calorific energy content. Feedstocks investigated include Tahoe chips, Pinion/Juniper chips, Rice hulls, and Corn Stover pellets pre-treated at 215 °C, 255 °C, and 295 °C. Chemical analyses were conducted on the gaseous, aqueous, and solid HTC products. Energy contents of the solid biochar products were measured by calorimetry, and mass balances were ...
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.
