Název v původním jazyce

Novel type of pattern formation in droplet systems

Popis výsledku v původním jazyce

In nature we can observe pattern formation on various spatial and temporal scales; various patterns like spots, stripes, waves, spirals or dendrites could appear in both the inanimate word and in biological systems. The spontaneous formation of spatial or spatio-temporal patterns under homogeneous external conditions is a characteristic feature of systems far from equilibrium. The most familiar patterns are Rayleigh-Bénard convection, Taylor vortexes, snowflakes or ice crystal growth, fingering in the Hele-Shaw cell, Turing patterns, Belousov-Zhabotinsky reaction-diffusion system or pattern formation in a layer of starving Dictyostelium cells. Although we exemplified only a few examples of pattern formation, it is obvious that there are plenty of systems where the evolution of patterns in time has been intensively studied both experimentally and theoretically. The present work focuses on a novel type of pattern formation that, to the best of our knowledge, had not been described before. Recently, we have found that decanol droplets are able to form complex morphological patterns when they are placed on a thin layer of decanoate solution at far-from-equilibrium initial conditions. Intriguing patterns are observable depending on the initial composition of the system, namely the molar ratios of decanol and decanoate, optionally on the salt amount.
