Liquid marble formation: Spreading coefficients or kinetic energy?
Powder Technology, 2009 A liquid marble is a network of self-assembled hydrophobic powder around a droplet. The mechanism and driving force leading to the formation of liquid marbles have not been investigated.

Langmuir, 2007
Liquid marbles have been reported during this decade and have been argued to be potentially useful for microfluidic and lab-on-a-chip applications. The liquid marbles described to date have been composed of either water or glycerol as the liquid and hydrophobized lycopodium or silica as the stabilizing particles.

Electrowetting of Nonwetting Liquids and Liquid Marbles
Langmuir, 2006Transport of a water droplet on a solid surface can be achieved by differentially modifying the contact angles at either side of the droplet using capacitive charging of the solid-liquid interface (i.e., electrowetting-on-dielectric) to create a driving force.

Shaped composite liquid marbles
Journal of Colloid and Interface Science, 2014Shaped "cubic" non-stick droplets are reported. Shaped composite droplets were manufactured via a two-stage process. In the first stage, cubic foamed-polystyrene particles were hydrophilized with cold radiofrequency plasma. Then particles were wetted with water.

Stimulus-Responsive Liquid Marbles
Journal of the American Chemical Society, 2009Millimeter-sized "liquid marbles" are usually prepared using highly hydrophobic particles such as fluorosilane-treated lycopodium powder or alkylated silica sols. In the present work it is shown that "liquid marbles" can be prepared using sterically stabilized polystyrene latex; remarkably, such latex particles can be readily prepared by aqueous ...

The porous and superhydrophobic shell of a liquid marble prevents contact of its liquid core with outside surfaces, but allows gas transport. Liquid marble can therefore be used to sense gas or emit gas. Liquid marbles loaded with different indicators can simultaneously sense different gases via different mechanisms.

Osmotic evolution of composite liquid marbles
Journal of Colloid and Interface Science, 2021We hypothesized that the reported evolution (growth) of composite water marbles filled with saline water and coated with lycopodium dispersed in a thin layer of silicone oil is due to the osmotic mass transfer. The hypothesis is supported by the semi-empirical model of osmotic growth of small liquid marbles floating on distilled water.Saline composite,

Supergluing MOF liquid marbles
Chem. Commun., 2013Growth of NH(2)-MIL-53(Al) on alumina microparticles followed by post-synthetic modification with perfluorooctyl or caproic groups produces highly hydrophobic microparticles which are utilized for the formation of liquid marbles. Interfacial polymerization of ethyl-2-cyanoacrylate on the surface of the liquid marbles produces stable liquid capsules.

Interfacial crystallization in the polyhedral liquid marbles
Journal of Colloid and Interface Science, 2023We hypothesized that interfacial crystallization occurring within evaporated polyhedral liquid marbles may be controlled by hydrophilization of the polymer plates coating the marbles. The hypothesis was tested with polyhedral marbles coated with hydrophobized and cold plasma-hydrophilized PET (Polyethylene terephthalate) plates.Interfacial ...

Respirable liquid marble for the cultivation of microorganisms
Colloids and Surfaces B: Biointerfaces, 2013A liquid marble has a porous and superhydrophobic shell, which prevents the liquid core within the marble from making any contact with outside surfaces, but at the same time allows gases to transport freely across the shell. In this study we demonstrated the use of this unique property of liquid marbles to build respirable micro-biological reactors to ...
