Spreading of Ink

Caption

Investigators documented spreading of ink on a filter paper of Whatman Grade 1, and analyzed the process with a scanning electron microscope. Scanning micrographic results show paper fiber distribution, along with the micro-particle-image-velocimetry measure of random liquid movement through the network. Researchers conclude this evidence confirms diffusive dynamics at work in the spread of liquid through a paper matrix.
