Who peed on the floor?

There seems to be a big ring mark left over...

The coffee ring effect occurs when a droplet of a suspension evaporates on a substrate; this process can separate suspended nanoparticles (NPs) by size as a result of geometric constraints at the contact line of the evaporating droplet.

Compared with atmospheric spray pyrolysis, low-pressure spray pyrolysis (LPSP) has a unique capability of producing nanoparticles from micron-sized droplets (Fisenko et al. 2006).

In physics, a "coffee ring" is a pattern left by a puddle of particle-laden liquid after it evaporates. The phenomenon is named for the characteristic ring-like deposit along the perimeter of a spill of coffee. It is also commonly seen after spilling red wine. The mechanism behind the formation of these and similar rings is known as the coffee ring effect or in some instances, the coffee stain effect, or simply ring stain.
