There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Shortly after the pandemic began in 2020, researchers began examining the materials used for face masks in order to find the best protection available. Researchers from Georgia Tech included Nga Lee (Sally) Ng, professor in the School of Earth and Atmospheric Sciences with a joint appointment in the School of Chemical and Biomolecular Engineering. Lee, an aerosol scientist, and her research team tested 33 different commercially available materials such as single-layer woven fabrics (like cotton and polyester), mixed fabrics, non-woven materials, and materials used in hospitals.
