Previous studies reported that the drying time of a respiratory droplet on an impermeable
surface along with a residual film left on it is correlated with the coronavirus survival time …

We review recent studies on fomite transmission of COVID-19, caused by the novel
coronavirus. In particular, we focus on survival time of coronavirus on solid and porous …

Droplet evaporation on porous materials is a complex dynamic that occurs with spontaneous
liquid imbibition through pores by capillary action. Here, we explore water dynamics on a …

Displacing one fluid by another immiscible with it is a phenomenon of greatest importance
and exists in various applications from large scale oil productions to small scale …

ABSTRACT A face mask is essential personal protective equipment to mitigate the spread of
COVID-19. While a cloth mask has the least ability to prevent the passage of infectious …

Porous membranes filter by the virtue of their pore sizes in relation to the sizes of dispersals.
While this is essentially true for solid dispersals, it needs to be reframed when dispersals are …

In imbibition or drainage processes, a fluid displaces another immiscible one. If the
displacing fluid is wetting, this is an imbibition process and is drainage if otherwise. While …

The typical characteristic of a thin porous layer is that its thickness is much smaller than its in-
plane dimensions. This often leads to physical behaviors that are different from three …

N95 mask has emerged as a potential measure to mitigate the airborne transmission of
respiratory disease such as COVID-19. Herein, we experimentally investigated the impact …

In this study, a new experimental approach is proposed to investigate the absorption
properties of some selected retail paper towels. The samples were selected from two …
