We review studies of levitating droplets over liquid–gas interfaces and dry solid surfaces
with a focus on the physical mechanisms of levitation under different conditions. A …

When deposited on a superheated surface, a droplet can be levitated by its own vapour
layer, a phenomenon that is referred to as the Leidenfrost effect. This dynamic effect has …

Leidenfrost levitated droplets can be used to accelerate chemical reactions in processes that
appear similar to reaction acceleration in charged microdroplets produced by electrospray …

The use of geopolymers as adsorbent materials has been increasingly investigated in the
last few years, thanks to their highly intrinsic mesoporosity and ion exchange capability. As …

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 …

Regulation over the generation of the Leidenfrost phenomenon in liquids is vitally important
in a cutting fluid/tool system, with benefits ranging from optimizing the heat transfer efficiency …

Metakaolin-based geopolymer spheres shaped by three different drip** techniques were
investigated in terms of compressive strength and dye adsorption ability. Spheres were …

When a liquid drop falls on a solid substrate, the air layer between them delays the
occurrence of liquid–solid contact. For impacts on smooth substrates, the air film can even …

Saturn's ice‐covered moon Enceladus may contain the requisite conditions for life. Its
potentially habitable subsurface ocean is vented into space as large cryovolcanic plumes …

Geopolymer beads, conceived as alternative low cost adsorbents for wastewater treatment,
were shaped by a drip** technique in liquid nitrogen, through an ice-templating process …
