The recent development in basic and applied science and engineering of finely dispersed systems is presented in general, but more attention has been paid to the liquid-liquid finely dispersed systems or to the particular emulsions and double emulsions. The selected systems for theoretical and experimental research were emulsions and double emulsions that appeared in the pilot plant for extraction of uranium from wet phosphoric acid. The objective of this research was to try to provide a new or different approach to elaborate the complex phenomena that occur at developed liquid-liquid interfaces. New concepts were introduced, the first is a concept of an entity, and the corresponding classification of finely dispersed systems and the second concept consider the introduction of an almost forgotten basic electrodynamics element memristor, and the corresponding memristive systems. Based on these concepts a theory of electroviscoelasticity was proposed and experimentally corroborated using the selected representative liquid-liquid system. Also, it is shown that the droplet, and/or droplet-film structure, that is, selected emulsion and/or double emulsion may be considered as the particular example of memristive systems.

Hydrogen sulfide (HS) has been recognized as one of the three main gasotransmitters found extensively in tissues, regulating functions crucial for survival. In many pathological cases, its concentration drops from the intrinsic level, impairing healing and leading to unmet regeneration outcomes. A hybrid microparticle/hydrogel system was developed to sustainably release HS and regulate its level in deprived tissues.

In recent years, amino acids have garnered extensive attention as environmentally friendly, small-dose additives for modulating hydrate formation and aggregation behavior. Amino acids, due to their amphiphilic nature, can adsorb at the gas-liquid interface and on hydrate crystal surfaces, thereby modifying interfacial properties and influencing crystal growth patterns. In our measurements, the amino acids displayed a concentration-dependent "double effect".

Lutein and omega-3 fatty acids, particularly eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), offer significant health benefits, especially when consumed together. However, their incorporation in food is often low due to their instability during processing and storage. Meat products play an essential role in human nutrition and are generally deficient in lutein and omega-3 fatty acids.

We present a microfluidic strategy for fabricating high-concentration alginate microgels through a combination of shell-mediated gelation and osmotic shrinkage. Using a water-in-oil-in-water double emulsion platform, we introduce a thermally responsive oil shell that undergoes a phase transition upon cooling. This phase change allows spatial control over calcium ion diffusion into the alginate core by forming transient diffusion channels, resulting in localized and uniform ionic crosslinking.

Although intelligent superwettability materials with tunable wettability have been extensively studied in oil-water separation, they still exhibit several limitations including singular dimension of response, nondurable surface modification, and inadequate on-demand separation capabilities. Herein, we propose an ingenious strategy that combines pH-responsive polymer and shape memory material to achieve intelligent dual-regulation of surface wettability and pore size. A porous double-regulated foam (DRF) is obtained by uniformly mixing epoxy resin with PMMA--PDEAEMA solution and one-piece curing it through salt template method.
