We are glad to announce that our paper on “Dynamics of stain growth from sessile droplets on paper” has been published in Journal of Colloid and Interface Science. The study contributes to the fundamental understanding of the wicking mechanism. The proposed modeling technique allows the quantification and prediction of stain dynamics in a variety of industrially relevant situations that were previously deemed too complex. The wicking of a finite reservoir is a common process in the printing, textile, agriculture and medical industries, and the development of a method of prediction will assist in the design and optimisation of new technologies. This study also provides a rigorous and physically meaningful alternative to the semi-empirical Lucas-Washburn equation to describe the wicking kinetics of droplets in real porous media.
