“…The universal dependence of the contact angle during the first stage and of the radius of the droplet base during the second stage on the reduced time has been derived theoretically and confirmed experimentally for pure liquids [48]. The theory developed for pure liquids is applicable also to nanofluids [54], where a good agreement with the available experimental data has been found. However, in the case of evaporation of surfactant solutions the process deviates from the theory predictions for pure liquids at concentration below critical wetting concentration and is in agreement with the theory predictions at concentrations above it [52,53].…”

“…Recently a considerable progress in theoretical and experimental studies of simultaneous spreading and evaporation of liquid droplets on solid substrates has been achieved [47,48,49,50,51,52,53,54] in the case of both complete wetting [47] and partial wetting [48,49,50,51]. A universal behavior has been predicted and experimentally verified for both cases.…”

Interfaces can be called Smart and Green (S&G) when tailored such that the required technologies can be implemented with high efficiency, adaptability and selectivity. At the same time they have also to be eco-friendly, i.e. products must be biodegradable, reusable or simply more durable. Bubble and drop interfaces are in many of these smart technologies the fundamental entities and help develop smart products of the everyday life.Significant improvements of these processes and products can be achieved by implementing and manipulating specific properties of these interfaces in a simple and smart way, in order to accomplish specific tasks. The severe environmental issues require in addition attributing ecofriendly features to these interfaces, by incorporating innovative , or, sometime, recycle materials and conceiving new production processes which minimize the use of natural resources and energy. Such concept can be extended to include important societal challenges related to support a sustainable development and a healthy population.The achievement of such ambitious targets requires the technology research to be supported by a robust development of theoretical and experimental tools, needed to understand in more details the behavior of complex interfaces. A wide but not exhaustive review of recent work concerned with green and smart interfaces is presented, addressing different scientific and technological fields. The presented approaches reveal a huge potential in relation to various technological fields, such as nanotechnologies, biotechnologies, medical diagnostics, new or improved materials.

“…Indeed, such a transition between a smooth "coffee-ring stain" and fingering has been observed in previous drying droplet studies where it was attributed to Marangoni effects caused by small temperature differences through evaporative cooling. [62][63][64][65][66][67][68][69][70] Further support for the critical effect of small variations in chemical potential is the observation illustrated in Fig. 4a that unstable spheroidal nanoparticle assemblies or aggregates of diameters up to 3 μm constantly form, coalesce with other liquid-like aggregates and dissolve again (see the movie in the ESI † with corresponding playback time from 1:08 min to 1:12 min).…”

Dynamic growth modes of ordered arrays and mesocrystals during drop-casting of iron oxide nanocubes

The growth modes of self-assembled mesocrystals and ordered arrays from dispersions of iron oxide nanocubes with a mean edge length of 9.6 nm during controlled solvent removal have been investigated with a combination of visible light video microscopy, atomic force microscopy and scanning electron microscopy. Mesocrystals with translational and orientational order of sizes up to 10 μm are formed spontaneously during the final, diffusion-controlled, drop-casting stage when the liquid film is very thin and the particle concentration is high. Convection-driven deposition of ordered nanocube arrays at the edge of the drying droplet is a manifestation of the so called coffee-ring effect. Dendritic growth or fingering of rapidly growing arrays of ordered nanocubes could also be observed in a transition regime as the growth front moves from the initial three-phase contact line towards the centre of the original droplet.

“…It was demonstrated in Ref. [11] that there is no influence of the droplet volume on the contact angle measurement. In present experiments, the droplet volume was 2-3 μl for each measurement.…”
