Liquid Marbles Swallowing One Another and Extraneous Objects
نویسندگان
چکیده
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.

Liquid Marble Interaction Gate for Collision-Based Computing
Liquid marbles are microlitre droplets of liquid, encapsulated by self-organised hydrophobic particles at the liquid/air interface. They offer an efficient approach for manipulating liquid droplets and compartmentalising reactions in droplets. Digital fluidic devices employing liquid marbles might benefit from having embedded computing circuits without electronics and moving mechanical parts (a...
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 کاملEdible liquid marbles and capsules covered with lipid crystals.
Liquid marbles are water droplets covered with solid particles. Here we show a method for the preparation of edible liquid marbles and capsules covered with fatty acid crystals and triacylglycerol crystals. We prepared liquid marbles using a simple method; namely, a water droplet was rolled on lipid crystals in petri dishes. The resulting marbles were converted to capsules covered with a lipid ...
متن کاملLiquid Marble as Micro - Bioreactor
Liquid marbles can be used as micro-bioreactors, thanks to their unique properties. On the one hand, the highly porous, non-adhesive, and hydrophobic shell of liquid marbles efficiently inhibits any direct contact between the liquid core of the marble and the surface that supports it, while allowing oxygen and carbon dioxide to pass through. On the other hand, the finite volume of liquid in liq...
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...
