We have recently shown how path integral simulations can bestreamlined by decomposing the potential into a sum of rapidlyvarying short-range and slowly varying long-range contributions.In this talk, I will describe an efficient way to perform thisdecomposition for systems with electrostatic interactions, andillustrate the method with an applicat...

Microfluidic devices without walls have many advantages over channel-based devices. In droplet-based ("digital") microfluidics, liquids are transported as droplets between parallel plates, rather than as streams. The droplets are created, moved, joined and divided by applying electrical potentials sequentially between electrodes buried beneath a...

The dynamics of a lipid bilayer membrane is investigated in several different situations. Our model accounts for the transport of lipids along each monolayer, and intermonolayer friction, as well as the membrane fluidity and resistance to bending. First we consider a nearly-spherical vesicle in a shear flow. In this near-spherical limit we can r...

With the advent of nanofabrication technologies,nano-channels with dimensions smaller than the Debye screeninglayer can now be fabricated to allow scrutiny of the variousanomalous DC and AC I-V characteristics of ion-selectivemembranes at the single-pore level ' such knowledge isessential for rapid DNA sequencing, single-moleculesensing/identifi...

Since Worthington, many situations generated by impacts in liquids weredocumented and explored. In this spirit, we would like to present severalrecent observations related to the behavior of projectiles after they hitdifferent kinds of liquids. We first discuss the impact on soap films, andnaturally extend these observations to foams, focussing ...

We investigate the properties of a model describing the motion of liquid drops sitting on a flat surface. Here we consider the so-called quasi-static approximation model, where the speed of the contact line between the fluid and the surface is much slower than the capillary relaxation time.We show that, under a geometric constraint on the initia...

We study experimentally complex shaped partially wet particles on liquid-air interfaces. The interface deforms to satisfy the contact angle boundary conditions at the particle-liquid-air contact line. The deformations create excess liquid-air interface. When deformation fields between neighboring particles overlap, the excess area decreases as t...

When subjected to electric fields, liquids exhibit a large range of dynamic and kinematic phenomena. This lecture focuses on the liquid electromechanical effects commonly exploited to dispense, move, and manipulate small liquid masses (including droplets) in microfluidic applications. Irrespective of the fine details, the net, observable force i...

Coarsening dynamics are gradient flow dynamics. This means, the evolution of an out-of-equilibrium system towards relaxation follows the steepest descent in an energy landscape. In many two-phase systems, the energy is proportional to the area of the interfacial layer between these phases. Therefore, descent in an energy landscape corresponds to...
