Schematic of capillary imbibition and thin-film formation on porous surfaces

Caption

In Physics of Fluids, researchers show a droplet remains liquid for a much shorter time on a porous surface, making it less favorable to survival of the virus. Left: Schematic of capillary imbibition and thin-film formation on porous surfaces; right: a comparative picture depicting the time varying film thickness on glass (an impermeable material) and paper (a porous material) in the context of coronavirus survival.
