In the event that you do touch a surface that is contaminated with live COVID-19 droplets, if you proceed to touch your nose, eyes, or mouth, you are “taking the virus from the surface and ...
Fluorine-containing durable water repellent makes a fabric water-resistant. Fluorinated surfactants or fluorosurfactants are a subgroup of PFAS characterized by a hydrophobic fluorinated "tail" and a hydrophilic "head" that behave as surfactants. These are more effective at reducing the surface tension of water than comparable hydrocarbon ...
In 1938, polytetrafluoroethylene (DuPont brand name Teflon) was discovered by accident by a recently hired DuPont Ph.D., Roy J. Plunkett. While working with tetrafluoroethylene gas to develop refrigerants, he noticed that a previously pressurized cylinder had no pressure remaining. In dissecting the cylinder, he found a mass of white solid in a ...
The latest variant of COVID-19 is one of the most easily spread variants. Ada County has seen over a 20% increase in COVID-19 cases in July.
