Research Interests

I am a professor in Chemistry at the University of Colorado in Boulder. My research group focuses on clouds and aerosols in atmospheric chemistry. Research topics include stratospheric ozone depletion, cirrus cloud chemistry, tropospheric clouds and particles, the interaction between clouds and climate, and the chemistry of planetary atmospheres including Titan and Mars. Our work is laboratory-based; we use simulation chambers to identify key atmospheric aerosol processes important in different environments. Novel laboratory techniques include aerosol optical levitation, aerosol mass spectrometry, and aerosol optical techniques such as photo acoustic and Raman spectroscopies. 

Current Research

Research in the Tolbert Group is focused on heterogeneous atmospheric chemistry, specifically determining the chemical, physical, and optical properties of atmospheric particulate. One area of recent emphasis has been the determination of aerosol phase state. Aerosol phase is important for heterogeneous chemistry, aerosol climate effects, and visibility reduction due to aerosols. The process of deliquescence refers to a crystalline particle taking up water at a specific relative humidity to become an aqueous droplet and is well understood. The converse process, efflorescence, is a nucleation event whereby an aqueous droplet nucleates to reform the crystalline phase. Despite being studied for decades, the efflorescence of atmospheric aerosols remains uncertain.

We have developed a new optical levitation technique to probe aerosol efflorescence of freely floating uncharged particles as a function of relative humidity (RH). In particular, we examine a novel efflorescence path—contact efflorescence initiated by a collision between two aerosol particles. In the figure below, we illustrate what might happen when an amorphous particle (simulating an organic aerosol in the atmosphere) collides with an aqueous droplet of sodium chloride (salt). The light scattering by the levitated particles is shown in green while the illustrations depict the corresponding physical processes. In panel A, the light scattering by the salt appears as a series of horizontal lines, indicative of Mie scattering from a liquid droplet. The organic particle is approaching from below and a collision has not yet occurred. Panel B shows the results of a collision below 68 percent RH that caused nucleation to form crystalline sodium chloride, where the linear light scattering pattern has been replaced by random scattering due to the crystal facets. For very high values of RH above 69 percent, instead of nucleation, the salt droplet simply captures the organic particle, slightly disrupting the linear light scattering pattern, Panel C. Of note: when the salt droplet has immersed the organic particle, a much lower RH is required for efflorescence.

This study shows that the same particle can cause salt to effloresce at a much higher RH if it is in contact with the foreign nucleus rather than being immersed in the droplet. Thus, there is a fundamental difference between nucleation from the “outside-in” and nucleation from the “inside-out.” These studies have revealed a new aerosol process of possible importance in the atmosphere, so called “contact-efflorescence.” Ongoing studies are probing the atmospheric significance of contact efflorescence in a variety of environments.
