Liquid marbles have promising applications in the field of microreactors, where the opening and closing of their surfaces plays a central role. We have levitated liquid water marbles using an acoustic levitator and, thereby, achieved the manipulation of the particle shell in a controlled manner. Upon increasing the sound intensity, the stable levitated liquid marble changes from a quasi-sphere to a flattened ellipsoid. Interestingly, a cavity on the particle shell can be produced on the polar areas, which can be completely healed when decreasing the sound intensity, allowing it to serve as a microreactor. The integral of the acoustic radiation pressure on the part of the particle surface protruding into air is responsible for particle migration from the center of the liquid marble to the edge. Our results demonstrate that the opening and closing of the liquid marble particle shell can be conveniently achieved via acoustic levitation, opening up a new possibility to manipulate liquid marbles coated with non-ferromagnetic particles.

“…[1][2][3][4][5] The formed particle shell prevents direct contact of the liquid with a solid substrate, thus reducing significantly the surface friction of the liquid marble on it. 3 Liquid marbles are therefore excellent micro-reservoirs, which can be easily transported without any leakage of the enwrapped liquid.…”

“…One is the development of roughness-induced superhydrophobic surfaces with small contact angle hysteresis678910111213141516171819 and the other is based on lubricant-infused surfaces202122. In the research line of roughness-induced superhydrophobic surfaces, the studies of frost formation mainly focus on individual droplets, either deposited67891011 or impacted1213141516. However, the working conditions encountered in industrial applications are more conducive to condensation frosting (formation of supercooled condensate and subsequent freezing into frost)23242526.…”

Despite extensive progress, current icephobic materials are limited by the breakdown of their icephobicity in the condensation frosting environment. In particular, the frost formation over the entire surface is inevitable as a result of undesired inter-droplet freezing wave propagation initiated by the sample edges. Moreover, the frost formation directly results in an increased frost adhesion, posing severe challenges for the subsequent defrosting process. Here, we report a hierarchical surface which allows for interdroplet freezing wave propagation suppression and efficient frost removal. The enhanced performances are mainly owing to the activation of the microscale edge effect in the hierarchical surface, which increases the energy barrier for ice bridging as well as engendering the liquid lubrication during the defrosting process. We believe the concept of harnessing the surface morphology to achieve superior performances in two opposite phase transition processes might shed new light on the development of novel materials for various applications.

A liquid marble is a liquid droplet coated with hydrophobic powder which enables the marble to be manipulated like a soft solid. Recently, liquid marbles have been used in applications such as micro bioreactors for three-dimensional cell cultures and could be a new platform for digital microfluidics. Despite its potential significance, there is a lack of a systematic, thorough review and discussion on the manipulation schemes for liquid marbles. This paper presents past and recent manipulation schemes for liquid marbles. This paper discusses the major working principles, their advantages and drawbacks. Finally, the paper concludes with recent applications and the challenges of this research area.
