Becky's CC-Raman Paper Highlighted in AAAR Newsletter

In very exciting news, Becky Craig's recent paper in Aerosol Science and Technology was chosen as the "Article Highlight" in the Summer Issue of the American Association for Aerosol Research's newsletter Particulars. The writeup emphasized the potential for Raman analysis, specifically automated Raman analysis to enable ambient temperature and pressure chemical characterization of components in atmospheric aerosols. Great work Becky!

Ault Lab trip to UNC-Chapel Hill!

Dr. Ault and Ault Lab graduate students recently took a trip to Chapel Hill, North Carolina to meet with Dr. Jason Surratt’s group regarding a collaborative project. By combining the Ault Lab’s single particle microscopic and spectroscopic techniques with the Surratt Lab’s expertise with high resolution mass spectrometry of secondary organic aerosol (SOA) and chemical ionization mass spectrometry (CIMS) of trace gases, the two groups will investigate how relative humidity and differing organic precursors affect the viscosity and phase of resulting aerosols. Together, the groups are investigating the reactive uptake of isoprene epoxydiol onto SOA particles to better understand aerosol processes and their role in human health and the rapidly changing climate.

New Review on Methods for Atmospheric Aerosol Chemistry Research

A new review from the Ault Group (Prof. Ault and Dr. Jessica Axson) is focused on advances in atmospheric aerosol instrumentation in the past 5 years. The title is " Atmospheric Aerosol Chemistry: Spectroscopic and Microscopic Advances" and it was included in Analytical Chemistry's "Fundamental and Applied Reviews in Analytical Chemistry 2017". Instrumentation used for aerosol analysis ranging from electron microscopy to Raman microspectroscopy to optical tweezers and many more are covered. The motivation for using these methods, such as physicochemical mixing state as well as instrumental size ranges are discussed.

Prof. Ault receives CAREER grant from National Science Foundation

Prof. Ault was recently awarded a CAREER grant from the National Science Foundation entitled " CAREER: Molecular Studies of Phase Separations and Internal Structure in Individual Particles" This grant will focus on understanding the molecular level processes occurring within complex atmospheric aerosol particles. The research will couple new instrumentation (atomic force microscopy with infrared - AFM-IR) with existing instrumentation used by the Ault Group (Raman microspectroscopy and electron microscopy). New information about how aerosols change as a function of relative humidity (RH) with respect to viscosity and phases separations will be determined for particles of different sizes and compositions.

Prof. Ault elected as Vice-Chair of the Atmospheric Chemistry Working Group for AAAR

Dr. Ault was elected this week as the vice-chair of the "Atmospheric Chemistry" working group for the American Association for Aerosol Research (AAAR). This position is elected across the entire AAAR membership. From AAAR "These leaders are selected for a 2-year rotation, serving as Vice-Chair for the first year and then becoming Chair for the second year. The Chair presides over the WG meeting at the annual conference and then serves on the conference program committee, planning the next year's annual conference." Dr. Ault is excited to provide service to a community he has been involved with for the past decade!
