An extended meniscus of a ferrofluid solution on a silicon surface is subjected to axisymmetric, non-uniform magnetic field resulting in significant forward movement of the thin liquid film. Image analyzing interferometry is used for accurate measurement of the film thickness profile, which in turn, is used to determine the instantaneous slope and the curvature of the moving film. The recorded video, depicting the motion of the film in the Lagrangian frame of reference, is analyzed frame by… 
Electrodewetting and Wetting of an Extended Meniscus.
Here, we report the intriguing movements of an extended liquid meniscus on a silicon substrate under the influence of sinusoidal alternating current (AC) voltages at different operating frequencies.
Maximum Spreading of Impacting Ferrofluid Droplets under the Effect of Nonuniform Magnetic Field.
This article investigates the maximum spreading of ferrofluid droplets impacting on a hydrophobic surface under nonuniform magnetic fields. A generalized model for scaling the maximum spreading is

Meniscus of a Magnetic Fluid in the Field of a Current-Carrying Wire: Three-Dimensional Numerical Simulations
Three-dimensional calculations of the meniscus of a magnetic fluid placed around a current carrying vertical and cylindrical wire reveal that the numerically assumed isothermal conditions are not present in the experiment, particularly at the great strength of the applied current.


Electrowetting of partially wetting thin nanofluid films.
It is observed that the presence of negatively charged, suspended nanoparticles significantly changes the electric-field-induced spreading and contact line dynamics of partially wetting liquid films.
Electric field enhanced spreading of partially wetting thin liquid films.
Equilibrium and dynamic electrowetting behavior of ultrathin liquid films of surfactant (SDS) laden water over silicon substrate (with native oxide) is investigated and contact line instability resulting in emission of droplets from the curved meniscus has been observed.

The microscopic details of fluid flow and heat transfer near the contact line of an evaporating extended meniscus of heptane formed between a horizontal substrate and a “washer” were studied at low
Experimental investigation of evaporation and condensation in the contact line region of a thin liquid film experiencing small thermal perturbations.
Image-analyzing interferometry technique is successfully used to study microscale transport processes related to a curved microfilm on a solid substrate and the numerical solution of a model that takes into account the balance between the suction and the capillary force is compared with the data to elicit new insights into the evaporation/condensation phenomena.
