The Capstone Conference for the Alfred P. Sloan Foundation’s Chemistry of the Indoor Environment program was held from Oct 18-20 at the National Academy of Sciences in Washington, DC. Many projects from the group and our collaborators were presented. It was great that the community had this final opportunity to come together to share their findings (and to get a great group photo)! While the program may be at an end, it will not be the end of our work on indoor atmospheric chemistry!!
