Liquid marbles are liquid drops made non-wetting by the use of a powder which coats them. Because of the absence of a contact line, quick motions without leakage of small amounts of liquid are allowed, which can be of interest in microfluidic applications. After characterizing the static liquid marble, we focus on its properties and study experimentally the viscous motion of liquid marbles. Then, we describe qualitatively possible ways for putting marbles into motion and quantify the robustness of this object.

Crater Morphology

When a granular material is impacted by a sphere, its surface deforms like a liquid yet it preserves a circular crater like a solid. Although the mechanism of granular impact cratering by solid spheres is well explored, our knowledge on granular impact cratering by liquid drops is still very limited. Here, by combining high-speed photography with high-precision laser profilometry, we investigate liquid-drop impact dynamics on granular surface and monitor the morphology of resulting impact craters. Surprisingly, we find that despite the enormous energy and length difference, granular impact cratering by liquid drops follows the same energy scaling and reproduces the same crater morphology as that of asteroid impact craters. Inspired by this similarity, we integrate the physical insight from planetary sciences, the liquid marble model from fluid mechanics, and the concept of jamming transition from granular physics into a simple theoretical framework that quantitatively describes all of the main features of liquid-drop imprints in granular media. Our study sheds light on the mechanisms governing raindrop impacts on granular surfaces and reveals a remarkable analogy between familiar phenomena of raining and catastrophic asteroid strikes.

Liquid marbles are hydrophilic liquid drops encapsulated with hydrophobic powder materials. The liquid marbles have potential applications in drug delivery, water purification, ferrofluidic device and sensor microfabrication. In this work, a new type of polytetrafluoroethylene nanoparticle (PTFE-NP) liquid marbles were fabricated successfully using mixing method. The morphology of the formed liquid marbles was characterized under different conditions, and novel properties of the PTFE-NP liquid marbles were investigated and demonstrated.
