Spontaneous emulsification

open access: yesCurrent Opinion in Colloid and Interface Science, 2016
Spontaneous emulsification may occur when immiscible liquids in non-equilibrium conditions are in contact. This phenomenon is triggered by gradients of chemical potential between the phases, which under certain conditions lead to negative values of free ...

Premix emulsification: A review

open access: yesJournal of Membrane Science, 2010
Membrane emulsification is known to be a mild technique that renders narrowly dispersed emulsions at energy inputs that are orders of magnitude lower than in traditional emulsification techniques.

Emulsification Properties of Pectin

2020
In this chapter, the efficacy of pectin as emulsifier and the structural components that influence its emulsification properties are discussed. The complex molecular structure of pectin makes the assignment of structure vs. function relationships particularly challenging.

Phaco-Emulsification of Cataracts

AJN, American Journal of Nursing, 1975
technique of phaco-emulsification. This technique shortens the patient's hospitalization and his visual rehabilitation period. Essentially it is the emulsification and aspiration of a cataract through a tiny incision. A cataract is a clouding of the lens of the eye, which usually is transparent.

Ultrasonic Emulsification

The Journal of the Acoustical Society of America, 1958
The ultrasonic emulsification of various liquid pairs has been investigated at several frequencies in the range of 104 to 106 cycles/sec with relatively uniform ultrasonic fields at intensities less than 10 w/cm2 as well as in the nonuniform fields from focused transducers with maximum intensities of the order of 103 w/cm2. Cavitation conditions in the

Microsystems for Emulsification

2016
Emulsions are important pharmaceutical preparations that are traditionally prepared by techniques like high-shear mixing and high-pressure homogenization. In recent years, microstructured devices have attained increasing importance with regard to emulsion preparation.
