Detailed Analysis of Complex Chemical Mixtures
Complex chemical mixtures (e.g., fuels, environmental air, human breath, food, perfumes, pharmaceuticals) are combinations of tens, hundreds, or thousands of chemicals, and of which the composition is qualitatively and quantitatively not fully known. Dr. Vozka research group utilizes comprehensive two-dimensional gas chromatography (GCxGC) techniques for quantitative and qualitative (targeted and untargeted) analyses of various gas and liquid samples.
Microplastics (MPs) have been found in drinking water, plant roots, animals, human organs, as well as in the human placenta. MPs release toxic substances (additives originating from plastics) or serve as carriers for other organic compounds and pathogens. Their impact on human health is potentially significant but still unknown. Dr. Vozka research group utilizes GCxGC techniques together with headspace and SPME fiber injections for quantitative and qualitative analyses of MPs samples.
Data analysis is an important step for extracting information from chemical systems. Our main goal is to fundamentally understand and describe how the chemical composition influences the properties of complex chemical mixtures on a molecular level. Current projects include the description of the relationship between hydrocarbon mixtures' chemical composition and their freezing points.
Chemical Conversion of Plastic Waste into Fuel
By 2050, there will be more plastic waste in oceans than fish. Our lab collaborates with Nien-Hwa Linda Wang, Maxine Spencer Nichols Professor of Chemical Engineering from Purdue University to improve her new chemical conversion process. Dr. Wang's technology utilizes plastic wastes and converting them into useable chemicals, polymers, and liquid transportation fuels such as gasoline and diesel.
