Remotely Controllable Liquid Marbles
With the ongoing need for miniaturized systems in many biological and chemical applications, there is an increasing demand for the development of versatile methods for controllable transport and manipulation of small volumes of liquids. [ 1–9 ] Recently, liquid marbles — liquid droplets encapsulated by self-organized hydrophobic particles at the liquid/air interface — have been revealed as a ne...
متن کاملCoalescence of electrically charged liquid marbles.
In this work, we investigated the coalescence of liquid water marbles driven by a DC electric field. We have found that two contacting liquid marbles can be forced to coalesce when they are charged by a sufficiently high voltage. The threshold voltage leading to the electro-coalescence sensitively depends on the stabilizing particles as well as the surface tension of the aqueous phase. By evalu...
متن کاملLiquid marbles: topical context within soft matter and recent progress.
The study of particle stabilized interfaces has a long history in terms of emulsions, foams and related dry powders. The same underlying interfacial energy principles also allow hydrophobic particles to encapsulate individual droplets into a stable form as individual macroscopic objects, which have recently been called "Liquid Marbles". Here we discuss conceptual similarities to superhydrophobi...
متن کاملLiquid Marbles Swallowing One Another and Extraneous Objects
Forced coalescence of liquid marbles is reported. Liquid marbles were connected by a glass rod hydrophilized with cold radiofrequency plasma. The process resulted in formation of Janus-marbles. “Sandwich” marbles enclosing solid foamed polystyrene particles and built from immiscible liquids are reported. A broad variety of organic and non-organic powders gives rise to Janus and “sandwich” marbles.
متن کاملCapillary origami: superhydrophobic ribbon surfaces and liquid marbles
In the wetting of a solid by a liquid it is often assumed that the substrate is rigid. However, for an elastic substrate the rigidity depends on the cube of its thickness and so reduces rapidly as the substrate becomes thinner as it approaches becoming a thin sheet. In such circumstances, it has been shown that the capillary forces caused by a contacting droplet of a liquid can shape the solid ...
