Shape evolution and splitting of ferrofluid droplets on a hydrophobic surface in the presence of a magnetic field

U Banerjee, AK Sen - Soft Matter, 2018 - pubs.rsc.org
We elucidate the phenomena of dynamic wetting, shape evolution and splitting of ferrofluid
(FF) droplets on a hydrophobic surface under the influence of a magnetic field. In the case of …

Vibration-induced floatation of a heavy liquid drop on a lighter liquid film

A Pototsky, A Oron, M Bestehorn - Physics of Fluids, 2019 - pubs.aip.org
We carry out a theoretical study of vibration-induced saturation of the Rayleigh-Taylor
instability for an isolated liquid drop on the surface of a less dense finite-thickness carrier …

Understanding wetting dynamics and stability of aqueous droplet over superhydrophilic spot surrounded by superhydrophobic surface

B Majhy, VP Singh, AK Sen - Journal of colloid and interface science, 2020 - Elsevier
Patterned superhydrophilic-superhydrophobic (SHL–SHB) surfaces have shown promise in
droplet-based biochemical assays. However, fundamental understanding of the behavior of …

Dynamics of a water droplet over a sessile oil droplet: Compound droplets satisfying a Neumann condition

R Iqbal, S Dhiman, AK Sen, AQ Shen - Langmuir, 2017 - ACS Publications
We report the dynamics of compound droplets with a denser liquid (water) droplet over a
less dense sessile droplet (mineral oil) that satisfies the Neumann condition. For a fixed size …

C Buffone - Soft Matter, 2019 - pubs.rsc.org
We present a fascinating experimental investigation of the formation, stability and thermal
patterns of evaporating liquid lenses deposited on an evaporating or non-evaporating liquid …

Elastocapillary flow driven lab-on-a-membrane device based on differential wetting and sedimentation effect for blood plasma separation

RA Samy, AK Sen - Journal of Micromechanics and …, 2019 - iopscience.iop.org
We report an elastocapillary flow—driven lab on a membrane device based on differential
wetting and sedimentation effect for the separation of plasma from whole blood. Interaction …

Equilibrium shapes and floatability of static and vertically vibrated heavy liquid drops on the surface of a lighter fluid

A Pototsky, A Oron, M Bestehorn - Journal of Fluid Mechanics, 2021 - cambridge.org
A small drop of a heavier fluid may float on the surface of a lighter fluid supported by surface
tension forces. In equilibrium, the drop assumes a radially symmetric shape with a circular …

A new perspective on the wetting of a surface by the drops of an emulsion

SG Borkar - 2022 - search.proquest.com
Spinodal wetting theory of a drop on a solid substrate requires that a bridge be formed,
which connects the drop and the substrate, and that this bridge grows laterally to complete …

Lens Evaporation on Immiscible Liquid Surface with an Interfacial Cooling Effect

M Mi, J Jiang, S Zhang, X Dong, L Liu - ACS omega, 2022 - ACS Publications
A theoretical heat and mass transfer model of volatile liquid lens evaporation on the surface

Coexistence and Sudden Entrapment between Two Dissimilar, Miscible Oil Lenses

W Sun, Q Ren, Z Wang, F Yang - Langmuir, 2019 - ACS Publications
The property of substrates is one of the important factors determining the interaction
between two lenses (droplets). There likely exist different interactions between two dissimilar …
