This means that the oil or water droplets will not coalesce. On their own, hydrophobic surfactants cannot stabilize an emulsion. Although they are attracted to oil, and an oil-in-water emulsion forms, the emulsion will not stay stable for long and will eventually coalesce. [10]
Emulsified fuels are a type of emulsion that combines water with a combustible liquid, such as oil or fuel. An emulsion is a specialized form of dispersion that contains both a continuous phase and a dispersed phase. The most commonly utilized emulsified fuel is a water-in-diesel emulsion (also known as hydrodiesel). [1]
Pectin is used as a stabiliser in foods such as yogurt. A stabiliser or stabilizer is an additive to food which helps to preserve its structure. Typical uses include preventing oil-water emulsions from separating in products such as salad dressing; preventing ice crystals from forming in frozen food such as ice cream; and preventing fruit from settling in products such as jam, yogurt and jellies.
Figure 4: Neumann's triangle relating the surface energies and contact angles of three fluid phases coexisting in static equilibrium, as depicted in Figure 3. Figure 3 shows the line of contact where three phases meet. In equilibrium, the net force per unit length acting along the boundary line between the three phases must be zero. The ...

Second, they can form a water-in-oil emulsion, in which water is the dispersed phase and oil is the continuous phase. Multiple emulsions are also possible, including a "water-in-oil-in-water" emulsion and an "oil-in-water-in-oil" emulsion. [1] Emulsions, being liquids, do not exhibit a static internal structure.
Water expands when it freezes, Sperlich said, so people should drip indoor facets when temps dip below 32 degrees. Just make sure you drip the farthest faucet from your main valve. "You don't have ...
The royal kids might not be allowed to keep some of their Christmas presents from the public this year thanks to the family's strict rules about gift giving.
