Probing Phase States of Individual Sub-micron Particles at Various Relative Humidity and Temperature
EMSL Project ID
51590
Abstract
The viscosity of organic aerosols is a pivotal property to predict their health and environmental impact. Viscosity influences particle growth rate, diffusivity, chemical reactivity, and impacts the long-range transport of pollutants. The viscosity of particles is strongly dependent on relative humidity and temperature. Submicron size organic aerosol dominate aerosol population, however, current techniques are limited by a narrow range of viscosity or particle size (>20µm). We propose to develop a novel platform integrated in environmental scanning electron microscope to probe viscosity of field collected individual submicron particles as a function of temperature and relative humidity.
