Acoustic levitation uses acoustic radiation forces to counteract gravity and suspend objects
in mid-air. Although acoustic levitation was first demonstrated almost a century ago, for a …

The need for miniaturised reaction systems has led to the development of various
microreactor platforms, such as droplet-based microreactors. However, these microreactors …

Spatiotemporally controllable droplet manipulation is essential in diverse applications,
ranging from thermal management to microfluidics and water harvesting. Despite …

The study of solid particles residing at fluid–fluid interfaces has become an established area
in surface and colloid science recently, experiencing a renaissance since around 2000 …

Remote control of the locomotion of small objects is a challenge in itself and may also allow
for the stimuli control of entire systems. Here, it is described how encapsulated liquids …

“Liquid marbles” are liquid‐in‐gas dispersed systems stabilized by hydrophobic solid
particles adsorbed at the gas‐liquid interface. The structure, stability and movement of these …

Liquid marbles are nonstick droplets wrapped by micro-or nanometrically scaled colloidal
particles, representing a platform for a variety of chemical, biological, and microfluidics …

Liquid marbles, that is, liquid drops coated by a hydrophobic powder, do not wet any solid or
liquid substrate, making their transport and manipulation both highly desirable and …

The technique of acoustic levitation normally produces a standing wave and the potential
well of the sound field can be used to trap small objects. Since no solid surface is involved it …

Liquid marbles are droplets with volume typically on the order of microliters coated with
hydrophobic powder. Their versatility, ease of use and low cost make liquid marbles an …
