Drop deposition on surfaces with contact-angle hysteresis: Liquid-bridge stability and breakup
Amir Akbari, Reghan J. Hill
We study the stability and breakup of liquid bridges with a free contact line on a surface with contact-angle hysteresis under zero-gravity conditions. Theoretical predictions of t…
Stability and folds in an elastocapillary system
Amir Akbari, Reghan J. Hill, Theo G. M. van de Ven
We examine the equilibrium and stability of an elastocapillary system to model drying-induced structural failures. The model comprises a circular elastic membrane with a hole at th…
Catenoid stability with a free contact line
Amir Akbari, Reghan J. Hill, Theo G. M. van de Ven
Contact-drop dispensing is central to many small-scale applications, such as direct-scanning probe lithography and micromachined fountain-pen techniques. Accurate and controllable…
Electric-field-enhanced transport in polyacrylamide hydrogel nano-composites
Reghan J. Hill
Electroosmotic pumping through uncharged hydrogels can be achieved by embedding the polymer network with charged colloidal inclusions. Matos and co-workers (2006) recently used the…
Electric-field-induced displacement of a charged spherical colloid embedded in an elastic Brinkman medium
Reghan J. Hill, Martin Ostoja-Starzewski
When an electric field is applied to an electrolyte-saturated polymer gel embedded with charged colloidal particles, the force that must be exerted by the hydrogel on each particle…
Reverse-selective diffusion in nanocomposite membranes
Reghan J. Hill
The permeability of certain polymer membranes with impenetrable nanoinclusions increases with the particle volume fraction (Merkel et al., Science, 296, 2002). This intriguing obse…
