IRP Proposals Accepted February 11 - March 25
The CIRES Innovative Research Program will begin accepting applications February 11; all materials are due March 25 through this InsideCIRES link.
The IRP is designed to stimulate a creative research environment within CIRES and to encourage synergy between disciplines and research colleagues. The intent is to support small research efforts that can quickly provide concept viability or rule out further consideration. The program encourages novel, unconventional or fundamental research that might otherwise be difficult to fund. Funded projects are inventive, sometimes opportunistic, and do not necessarily have an immediate practical application or guarantee of success. This program supports pilot or exploratory studies, which may provide rapid results. Activities are not tightly restricted and can range from instrument development, lab testing, and field observations to model development, evaluation, and application.

Understanding the Fate of Amines: Reactions with Oxygenates by Mitch Alton, CU ANYL 3rd year, Browne group
"Atmospheric aliphatic amines and ammonia have been previously reported to participate in various chemical reactions including brown carbon formation, accretion reactions forming amides, imine and enamine formation, and acid-base cluster stabilization reactions that can enhance new particle formation. As anthropogenic reactive nitrogen emissions continue to increase to keep pace with world population and food demands, the interaction of these amines and ammonia with organic compounds in the atmosphere needs to be further investigated to better understand the impacts of these emissions on air quality and the environment. I will discuss a series of chamber experiments that investigated the effects of different aliphatic amines and ammonia on secondary aerosol formation from the ozonolysis of α-pinene without the use of seed aerosol. Using hierarchical clustering analysis, different fates of α-pinene ozonolysis products with amines/ammonia were identified. Various observed reactions between amines/ammonia and α-pinene ozonolysis products to form enamines, imines, amides, and acid-base clusters will be explored to show the complex chemistry that can occur during aerosol formation and growth. Finally, I will discuss how acid-base stabilization reactions are the most important contributions to particle nucleation in this system. "
