Harry,

I wish to thank you for the sharing of the Journal article. I have blasted it out to many people, some of whom are making masks for state agencies, friends, first responders, etc.

There is no telling how many people the article helped in ways that will never be known.

Thank you again,

All:

Some colleagues at Argonne National Lab have recently published "Aerosol Filtration Efficiency of Common Fabrics Used in Respiratory Cloth Masks" in ACS Nano. The DOI is:

Definitely a hearty read, but also good information.

Harry
