Dropwise condensation processes, where condensation occurs through small droplets on a solid surface, has been demonstrated to significantly improve heat transfer rates in comparison to film-wise condensation (where a whole surface is covered by a thin film of liquid). Dropwise condensation usually takes place on superhydrophobic surfaces, and one of the main engineering and scientific challeng...

Blue phases of liquid crystals represent unique ordered states of matter in which arrays of defects are organized into striking patterns. Most studies of blue phases to date have focused on bulk properties. In this work, we present a systematic study of blue phases confined into spherical droplets. It is found that, in addition to the so-called blue phases I and II, several new morphologies ari...

Simple methods to self-assemble coatings and films encompassing nanoparticles are highly desirable in many practical scenarios, yet scarcely any examples of simple, robust approaches to coat macroscopic droplets with continuous, thick (multilayer), reflective and stable liquid nanoparticle films exist. Here, we introduce a facile and rapid one-step route to form films of reflective liquid-like ...

In this seminar behaviour of liquid droplets on a very hot surface is presented and a simple model is introduced to describe droplet evaporation. Special cases where droplet dynamics is involved are mentioned, important processes and their qualitative description is presented. This seminar supplements a previous seminar Leidenfrost effect, presented in December 2011.

We report on a microfluidic device and droplet formation regime capable of generating clinical-scale quantities of liquid perfluoropentane droplets suitable in size and functionality for gas embolotherapy. We examine three modes of droplet formation in our flow-focusing device – geometry-controlled, dripping, and jetting – then use the dripping regime to generate highly monodisperse droplets in...
