Wetting and evaporation of multicomponent droplets

Z Wang, D Orejon, Y Takata, K Sefiane - Physics Reports, 2022 - Elsevier
Wetting and evaporation of sessile droplets are ubiquitous in nature and of importance to
many industrial and everyday processes. While most of the research on sessile droplets has …

Analysis of the equilibrium droplet shape based on an ellipsoidal droplet model

VA Lubarda, KA Talke - Langmuir, 2011 - ACS Publications
The extent of a droplet's spreading over a flat, smooth solid substrate and its equilibrium
height in the presence of gravity are determined approximately, without a numerical solution …

On the breakup of patterned nanoscale copper rings into droplets via pulsed-laser-induced dewetting: competing liquid-phase instability and transport mechanisms

Y Wu, JD Fowlkes, PD Rack, JA Diez, L Kondic - Langmuir, 2010 - ACS Publications
Nanolithographically patterned copper rings were synthesized, and the self-assembly of the
rings into ordered nanoparticle/nanodrop arrays was accomplished via nanosecond pulsed …

Regimes of thermocapillary migration of droplets under partial wetting conditions

JM Gomba, GM Homsy - Journal of Fluid Mechanics, 2010 - cambridge.org
We study the thermocapillary migration of two-dimensional droplets of partially wetting
liquids on a non-uniform heated substrate. An equation for the thickness profile of the droplet …

Electrokinetic Thin-Film Model for Electrowetting: The Role of Bulk Charges

S Goel, DS Pillai - Langmuir, 2023 - ACS Publications
The electrowetting behavior of a charge-carrying sessile droplet is relevant to applications
such as point-of-care diagnostics. Often biomedical assays involve droplets that contain …

Rheology dictated spreading regimes of a non-isothermal sessile drop

VT Mantripragada, A Poddar - Journal of Fluid Mechanics, 2022 - cambridge.org
In the present work, within the framework of thin film theory, we delineate the interaction
between the interfacial dynamics of thermal Marangoni flow and non-Newtonian rheology by …

Steady states of thin film droplets on chemically heterogeneous substrates

W Liu, TP Witelski - IMA Journal of Applied Mathematics, 2020 - academic.oup.com
We study steady-state thin films on chemically heterogeneous substrates of finite size,
subject to no-flux boundary conditions. Based on the structure of the bifurcation diagram, we …

Thermocapillary migration of droplets under molecular and gravitational forces

JR Mac Intyre, JM Gomba, CA Perazzo… - Journal of Fluid …, 2018 - cambridge.org
We study the thermocapillary migration of two-dimensional droplets of partially wetting
liquids on a non-uniformly heated surface. The effect of a non-zero contact angle is imposed …

Harnessing Polar Interactions Tunes the Stability of Ultrathin Polymer Solution Films

S Bhuyan, S Chandran, DS Pillai - Langmuir, 2024 - ACS Publications
The stability of ultrathin (< 100 nm) polymer films is essential in applications like protective
coatings. On the contrary, their instability may actually be desirable for the emergence of self …

An analytical solution for a partially wetting puddle and the location of the static contact angle

ME Diaz, J Fuentes, RL Cerro, MD Savage - Journal of colloid and interface …, 2010 - Elsevier
A model is formulated for a static puddle on a horizontal substrate taking account of
capillarity, gravity and disjoining pressure arising from molecular interactions. There are …
