Review of non-reactive and reactive wetting of liquids on surfaces.
Girish Kumar,K. Narayan Prabhu +1 more
TL;DR: Wettability is a tendency for a liquid to spread on a solid substrate and is generally measured in terms of the angle (contact angle) between the tangent drawn at the triple point between the three phases (solid, liquid and vapour) and the substrate surface.

Review of drop impact on heated walls
TL;DR: In this paper, a comprehensive review of published literatures concerning the fluid mechanics and heat transfer mechanisms of liquid drop impact on a heated wall is provided, divided into four parts, each centered on one of the main heat transfer regimes: film evaporation, nucleate boiling, transition boiling, and film boiling.

TL;DR: It is shown that uniform deposition of nanoparticles in aqueous suspensions can be attained easily by drying the droplet in an ethanol vapor atmosphere and can be used for depositing catalyst nanoparticles for the growth of single-walled carbon nanotubes as well as to manufacture plasmonic films of well-spaced, unaggregated gold nanoparticles.
Journal ArticleDOI
Evaporation and Marangoni driven convection in small heated water droplets.
TL;DR: Marangoni motion occurs and generates inside the droplet convection cells that furthermore exhibit small fluctuating motion as evaporation goes on, and shows a minimum that indicates the existence of qualitative changes in the evaporative regimes although the droplets is sessile.
Journal ArticleDOI
Effect of TiO2 nanoparticles on contact line stick-slip behavior of volatile drops.
TL;DR: An experimental investigation of the concomitant evaporation and (de)wetting behavior of sessile drops of ethanol, either pure, or containing small amounts of titanium oxide nanoparticles, finds distinct "stick-slip" pinning behavior of the triple line occurred when nanoparticles were added to the base liquid.

Wetting: statics and dynamics
TL;DR: In this paper, the authors present an attempt towards a unified picture with special emphasis on certain features of "dry spreading": (a) the final state of a spreading droplet need not be a monomolecular film; (b) the spreading drop is surrounded by a precursor film, where most of the available free energy is spent; and (c) polymer melts may slip on the solid and belong to a separate dynamical class, conceptually related to the spreading of superfluids.

Evaporation of a Sessile Droplet on a Substrate
Hua Hu and,Ronald G. Larson +1 more
TL;DR: In this article, the evaporation of a sessile droplet with a pinned contact line was investigated experimentally, by analytic theory and by computation using the finite element method (FEM).
Journal ArticleDOI
Pattern formation in drying drops
TL;DR: The drop itself can generate one of the essential conditions for ring formation to occur: contact line pinning, and it is shown that when self-induced pinning is the only source of pinning an array of patterns-that include cellular and lamellar structures, sawtooth patterns, and Sierpinski gaskets-arises from the competition between dewetting and contact linePinning.

Influence of Evaporation on Contact Angle
TL;DR: In this paper, the evaporation of sessile drops of water and n-decane placed on various substrates has been studied using a projection method, where drop dimensions and contact angle have been measured as a function of time.
