Synthesis and Development of Biologically and Environmentally Stimulated Polymers

Abstract:

This talk will focus on a metabolite responsive nanoparticle-protein complex and developing a polymer membrane for water purification.  The first half will discuss the development of a polymer hydrogel nanoparticle containing a known inhibitor for the enzyme lactate dehydrogenase that is specifically responsive to the cancer metabolite lactate.  The second half delves into the challenges posed by using a polymer of intrinsic microporosity for size exclusion of viruses and other freshwater biological contaminants.

Nitrogen Containing Secondary Organic Aerosols: Experiments and Air Quality Simulations

Abstract:

Secondary organic aerosol (SOA) is a large fraction of particulate matter (PM) worldwide and remains a large source of uncertainty in global models that aim to predict the radiative forcing contribution of PM. Moreover, while inorganic nitrogen contribution to PM is well represented in air quality models, missing from models is the contribution of nitrogen organic compounds (NOC) to PM. By studying the formation and the interesting optical properties of these NOC, we may improve our understanding of how SOA can influence climate.
