Agitating two immiscible liquids
researchgate.net
- Emulsions are formed by agitating two immiscible liquids, such as oil and water, in the presence of an emulsifier. Emulsifiers can be proteins, phospholipids, or even nanoparticles.

An emulsion is a mixture of two or more liquids that are normally immiscible (unmixable or unblendable) owing to liquid-liquid phase separation. Emulsions are part of a more general class of two-phase systems of matter called colloids.
Aug 12, 2023 · X-ray film displays the radiographic image. It is made up of several layers. The emulsion layer is the layer that produces the latent image. The latent image later developed into a visible film during film processing.
1.1 Introduction. Emulsions are a class of disperse systems consisting of two immiscible liquids [1–3]. The liquid droplets (the disperse phase) are dispersed in a liquid medium (the continuous phase). Several classes may be distinguished: oil-in-water (O/W), water-in-oil (W/O), and oil-in-oil (O/O).

An X-ray film, total thickness approx. 0.5 mm, is made up of seven layers, see figure 1-7: • a transparent cellulose triacetate or polyester base (d). On both sides of this base are applied: • a layer of hardened gelatine (a) to protect the emulsion • emulsion layer (b) which is suspended in gelatine, sensitive to radiation
The emulsion layers of films are made by dissolving pure silver in nitric acid to form silver nitrate crystals, which are mixed with other chemicals to form silver halide grains, which are then suspended in gelatin and applied to the film base.
Oct 3, 2020 · Emulsions are colloids, which are homogeneous mixtures consisting of particles larger than molecules that scatter light, but are small enough that they don’t separate. Emulsions consist of two parts: the dispersed phase and the dispersing medium (continuous phase).
Feb 1, 2021 · For these aims, experimental techniques need to be revisited, implemented and developed for the various levels of details and scales concerned with emulsions: interfacial adsorption layers, liquid films and droplet interaction, Ostwald ripening and collective dynamics.
