Evaporation of a drop, though a simple everyday observation, provides a fascinating subject
for study. Various issues interact here, such as dynamics of the contact line, evaporation …

Coffee-ring effect is an omnipresent phenomenon, it features the circular deposition on the
surface after the evaporation of a droplet containing particles. Ever since the seminal report …

Controlling the wetting behaviour of liquids on surfaces is important for a variety of industrial
applications such as water-repellent coatings and lubrication. Liquid behaviour on a surface …

The influence of the small ionic surfactant sodium dodecyl sulfate (SDS) on the evaporation
of drying colloidal droplets is quantitatively investigated. The addition of SDS leads to a …

We study the effects of Marangoni stresses on the flow in an evaporating sessile droplet, by
extending a lubrication analysis and a finite element solution of the flow field in a drying …

Self-assembly of quasi-spherical colloidal particles in two-dimensional (2D) arrangements is
essential for a wide range of applications from optoelectronics to surface engineering, from …

Particle deposit morphologies that resulted from evaporating ink-jetted microdroplets were
controlled by varying the ink compositions and concentrations. The ink was a well-dispersed …

The shape of deposits obtained from drying drops containing colloidal particles matters for
technologies such as inkjet printing, microelectronics, and bioassay manufacturing. In this …

Nonuniform evaporation from sessile droplets induces radial convection within the drop,
which produces the well-known “coffee-ring” effect. The evaporation also induces a gradient …

This paper reviews the past and recent studies on thermocapillarity in relation to
microfluidics. The role of thermocapillarity as the change of surface tension due to …
