Below are the finalists for the 2022 AAAR Aerosol Video Competition. Please vote by casting your paper ballots (included in your AAAR registration package) at the membership booth! You can vote for your favorite entry in three categories:

  1. Video
  2. Art: Microscopic Scale
  3. Art: Non-Microscopic (Larger) Scale

Entries for the Art Competition (both scales) can be viewed via the navigation bar at the top of the page.

Video #1: E-cig Aerosol Dynamics in the Lung

Haoxuan Chen (University of California, Los Angeles), Airi Harui (University of California, Los Angeles), Yu Feng (Oklahoma State University), Michael D. Roth (University of California, Los Angeles), Yifang Zhu (University of California, Los Angeles)

Find out what happened to e-cigarette aerosols after being inhaled into the lungs in this video! Researchers from UCLA and Oklahoma State University developed a ventilated artificial lung system fitted with 3D-printed human airways. The artificial lung has a temperature and humidity close to the real human lungs and can continuously breathe and vape!

Video #2: Aerosol Particles and Their Morphology

Kotiba Malek (University of Maryland, College Park) and Dewansh Rastogi (University of Maryland, College Park)

The morphology of aerosols has been a point of interest within the aerosol community. Aerosol particles are shown, using available instrumentations, to come in a variety of shapes: spherical and no-spherical.   What was once assumed to be only spherical in shape, the observed non-sphericity of aerosols have highlighted the importance of visualizing the aerosol particles and the characterization of their diameter sizes

Video #3: Visualisation of Respiratory Plume

Rory Monro (Fisher & Paykel), Dr. Jean Marshall, Mike Ronayne

Where does our breath go, and what is in it? We combine compelling CO2 videos with particle counting, to spark vital dialog on infection risk.

Video #4: Aerosol Light Interactions

Shruti Choudhary (University of Miami); Shalinee Kavadiya (University of Miami); and Pratim Biswas (University of Miami)

Imagine the richly colored sunset, rainbows, and pilot announcing the visibility on your flight to Raleigh, aerosol-light interactions are responsible for these phenomena. When aerosols interact with light, they absorb some and scatter the rest, which results in visible phenomena we see. Like, black smoke looks black because the aerosols absorb visible light. This video describes a visual demonstration of aerosol light interactions.
