Mr. Smilde’ art is short-lived, just like many oxidants and volatile organic compounds indoors. It can last a few seconds, and then the cloud is gone. He may need to make hundreds of clouds for one photo finish, just like chemists make hundreds (thousands?) of measurements for one manuscript. Indeed, Mr. Smilde’s visual art work resembles a scientific experiment.
Mechanistic studies of idealized model surfaces as well as work on surfaces of samples derived from real-world indoor environments, including actual homes, will help us better quantify sources and sinks of indoor air pollutants, improve the prediction of dynamic changes in indoor air chemistry, and open the door for the design of smart coatings or paints for controlling, mitigating, or preventing negative outcomes of indoor air chemistry.
One of the biggest conclusions from the ARTISTIC campaign is how much people and our indoor activities impact indoor air quality, from the emissions on our breath, the emissions that come from our activities and the chemical products that we use; these things all change the chemistry of indoor spaces.
