Annual Review of Fluid Mechanics | Year: 2013
The speed at which a liquid can move over a solid surface is strongly limited when a three-phase contact line is present, separating wet from dry regions. When enforcing large contact line speeds, this leads to the entrainment of drops, films, or air bubbles. In this review, we discuss experimental and theoretical progress revealing the physical mechanisms behind these dynamical wetting transitions. In this context, we discuss microscopic processes that have been proposed to resolve the moving-contact line paradox and identify the different dynamical regimes of contact line motion.

The invention relates to a method of manufacturing of a microneedle array comprising the steps of selecting a soft production mold comprising a set of microscopic incisions defining geometry of the microneedles, said soft production mold being capable of providing the microneedle array integrated into a base plate; using a filler material for abundantly filling the microscopic incisions of the soft production mold thereby producing the microneedle array with pre-defined geometry integrated into the base plate; wherein for the filler material a water or alcohol based ceramic or polymer-ceramic slurry is selected. The invention further relates to a microneedle array 16, a composition comprising a microneedle array, a system for enabling transport of a substance through a barrier and a system for measuring an electric signal using an electrode.

An apparatus for mass producing monodisperse microbubbles contains a microfluidic flow focusing device. The microfluidic flow focusing device includes a dispersed phase fluid supply channel having an outlet that discharges into a flow focusing junction, a continuous phase fluid supply channel having an outlet that discharges into the flow focusing junction, and a bubble formation channel having an inlet disposed at the flow focusing junction. The configuration of the flow focusing junction is such that, in operation, a flow of dispersed phase fluid discharging from the outlet of the dispersed phase fluid supply channel is engageable in co-flow by a focusing flow of continuous phase fluid discharging from the outlet of the at least one continuous phase fluid supply channel under formation of a gradually thinning jet of dispersed phase fluid that extends into the inlet of the bubble formation channel.
