This is an informative article. We release aerosols, with submicron particles (0.1–1 µm) dominating when we speak, whisper, sing, shout etc.

That’s why an N95 respirator is a good way to stop submicron particles from passing from our mouth and nose to others. And protects us from the aerosols generated by others.

New science for #ClimateSky. @washuengineers.bsky.social researchers estimated the submicron particle distribution over the United States. These are the tiniest of pollution particles and thus have the capacity to have more negative effects on human health. engineering.washu.edu/news/2025/Ti... 🧪
Tiny and toxic: Researchers track smaller air pollution particles across U.S. skies

I had to go back and take down some microfacets but they're basically gone now

Hello #AcademicBsky hivemind! Is there anyone out here (preferably from Australia / nearby) who uses FIB or BE lithography at submicron resolution on materials like quartz, and might be interested in collaborating with us on a cool new project?
