Journal ArticleDOI
Suppression of coffee ring: (Particle) size matters
TL;DR: In this article, a physical exposition on how particle size affects morphodynamics of the droplet drying at macro-nano length scales is presented, and the transition to a uniform deposit is found to be independent of the internal flow field and substrate properties.
Journal ArticleDOI
Universal evaporation dynamics of a confined sessile droplet
TL;DR: In this article, the evaporation timescale of a sessile droplet entrapped in a 3D confined fluidic environment has been studied, and it has been shown that the time evolution history of the droplet can be traced and universally merged.
Journal ArticleDOI
Insights into Vapor-Mediated Interactions in a Nanocolloidal Droplet System: Evaporation Dynamics and Affects on Self-Assembly Topologies on Macro- to Microscales.
TL;DR: This concept has been extended to a linear array of droplets to showcase how to custom design two-dimensional drop arrangements to create controlled surface patterns at multiple length scales.
Journal ArticleDOI
Confinement-induced alterations in the evaporation dynamics of sessile droplets
TL;DR: It is shown that confined droplets exhibit a universal behavior in terms of the temporal evolution of each evaporation mode irrespective of the channel length, which may turn out to be of profound importance in a wide variety of applications, ranging from surface patterning to microfluidic technology.
Journal ArticleDOI
Universal buckling kinetics in drying nanoparticle-laden droplets on a hydrophobic substrate.
TL;DR: It is demonstrated through scaling arguments that the growth of the cavity (which controls the final morphology or structure) can be described by a universal function.
