- blamazon 3y agoOkay, so "absorb" sounds like it's not be the exact right word. I am a layman here. But how long does it take for the outer few layers of glass to achieve a level of PFAS density which is meaningful to people seeking to use those outer layers? Do diffusion calculations offer insight into this?
- mensetmanusman 3y agoYes, that is surface diffusion. When anything lands in the surface that is ‘adsorption’. Then those molecules can either surface diffuse, desorb, or go somewhere else :) Usually water is adsorbed on everything we interact with.
