Self-propulsion of liquid marbles filled with aqueous alcohol solutions and placed on a water
surface is reported. The characteristic velocity of the marbles is ca. 0.1 m/s. The …

When a liquid is dropped on a surface significantly hotter than the liquid's boiling point, a
vapor film forms beneath the droplet creating an insulation layer sufficient enough to prevent …

Heat engines are based on the physical realization of a thermodynamic cycle, most
famously the liquid–vapour Rankine cycle used for steam engines. Here we present a …

When a liquid droplet is placed on a very hot solid, it levitates on its own vapor layer, a
phenomenon called the Leidenfrost effect. Although the mechanisms governing the droplet's …

Small intestine-targeted drug delivery by oral administration has aroused the growing
interest of researchers. In this work, the child-parent microrobot (CPM) as a vehicle protects …

When deposited on a hot bath, volatile drops are observed to stay in levitation: the so-called
Leidenfrost effect. Here, we discuss drop dynamics in an inverse Leidenfrost situation where …

Leidenfrost phenomena on nano-and microstructured surfaces are of great importance for
increasing control over heat transfer in high power density systems utilizing boiling …

In this paper, the self-propelled motion of Leidenfrost droplets on ratchet surfaces is
numerically investigated using a thermal multiphase lattice Boltzmann model with liquid …

Thermal management of high temperature systems through cooling droplets is limited by the
existence of the Leidenfrost point (LFP), at which the formation of a continuous vapor film …

The Leidenfrost effect occurs when an object near a hot surface vaporizes rapidly enough to
lift itself up and hover,. Although well understood for liquids,,,,,,,,,,,,, and stiff sublimable …
