Oil in water emulsions are currently used as safe solvents for vaccines. [23] It is important that these emulsion are stable and remain so for long periods of time. Polyelectrolyte stabilized emulsions could be used to increase the shelf life of vaccines. Researchers have been able to develop polyelectrolyte emulsions with more than six month ...
Sorbitan monooleate is used to stabilize emulsions by facilitating the mixture of non-miscible components like oil and water. It is particularly effective in forming stable W/O emulsions. [2] It reduces the interfacial tension between oil and water phases in an emulsion.
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]
It is commonly used as a viscosity modifier or thickener and to stabilize emulsions in both food and non-food products. It is used primarily because it has high viscosity , is nontoxic, and is generally considered to be hypoallergenic , as the major source fiber is either softwood pulp or cotton linter .
Creaming, in the laboratory sense, is the migration of the dispersed phase of an emulsion under the influence of buoyancy.The particles float upwards or sink depending on how large they are and density compared to the continuous phase as well as how viscous or how thixotropic the continuous phase might be.
A horizontal line in the diagram represents an isenthalpic process. A vertical line in the h–s chart represents an isentropic process. The process 3–4 in a Rankine cycle is isentropic when the steam turbine is said to be an ideal one. So the expansion process in a turbine can be easily calculated using the h–s chart when the process is ...
Therefore, since micro- means 10 −6 and emulsion implies that droplets of the dispersed phase have diameters close to 10 −3 m, the micro-emulsion denotes a system with the size range of the dispersed phase in the 10 −6 × 10 −3 m = 10 −9 m range. Note 3: The term “micro-emulsion” has come to take on special meaning. Entities of ...
Working fluids are often categorized on the basis of the shape of their T–s diagram. An isentropic process is depicted as a vertical line on a T–s diagram, whereas an isothermal process is a horizontal line. [2] Example T–s diagram for a thermodynamic cycle taking place between a hot reservoir (T H) and a cold reservoir (T C).
