Ultrafine Aerosols: The Good, the Bad, and the Mysterious

Breakfast 7:30 am I Lecture 8:00 am - 9:00 am
Ultrafine aerosols are nanometer-sized particles suspended in air. While they comprise a miniscule fraction of the mass of all airborne particles, they play an oversized role in human health and the Earth’s climate that is sometimes good, sometimes bad, and at times completely mysterious. I have traveled the world and created “atmospheres in a can” in my lab in order to shed light on these impacts. My main tool is the TDCIMS – an instrument that can obtain the “fingerprint” of the chemicals present in ultrafine particles. In this talk, I will share what TDCIMS measurements tell us about the good role that ultrafine particles play in the Earth’s climate system, the bad effects of ultrafine particles when they are inhaled from hookah pipes, and the mysterious appearance of nanometer-sized “fungal shrapnel” in the Great Plains of Oklahoma.
