Description

Research Topic Description, including Problem Statement:

The properties and dynamics of mixed aerosol particles depend on their phase, chemical composition, and morphology. The rates of reactions strongly depend on whether the condensed-phase reacting substances are available on the particle surface or obscured by non-reactive substances, or fully encapsulated by a protective shell. In particular, the chemical and physical processes associated with secondary organic aerosol (SOAs) formation are complex and varied with several knowledge gaps remaining. SOAs account for a significant fraction of ambient aerosols and so an understanding of their formation, properties, and dynamics is needed to address both climate change and human health. Additionally, accurate identification of aerosols in complex environments is vital to national security as many chemical threats are, or could be, delivered as aerosols. Understanding the role of particle morphology in the properties and dynamics of aerosols is critical to assessing threats in a timely manner. This solicitation seeks an approach for characterizing the morphology of aerosol particles to study how that effects chemical reaction dynamics and physical changes.

Example Approaches:

The focus of this effort is on developing an understanding of the role morphology plays in reaction dynamics of particle mixtures. Approaches may include experimental methods and/or computational approaches (compared to available experimental data for validation wherever possible). Relevant data and techniques may include aerosol mass spectrometry, electron resonance spectroscopy, photochemical aging processes, or other approaches. Variables to be considered include chemical composition, temperature variation, humidity levels, and particle formation methods. 

Relevance to the Intelligence Community (IC):

Develop/enhance capabilities to detect and identify chemical agents, and associated delivery systems. Develop/enhance capabilities to rapidly characterize the release of chemical, biological, radiological, nuclear, and/or related hazardous materials. Develop/enhance capabilities to conduct detailed sampling and chemical analysis across all states of matter.
