Jun 3, 2016 · In contrast to polydisperse bulk emulsions produced by mechanical shear or agitation, stable monodisperse or double emulsions can be generated using microfluidics, including co-flowing 7,8, T ...
May 26, 2021 · Emulsion stability in a flow field is an extremely important issue relevant for many daily-life applications such as separation processes, food manufacturing, oil recovery etc. Microfluidic ...
Mar 7, 2023 · In this perspective paper, we highlight the numerous open problems in the topic of stability of emulsions and foams, focusing on the simplest case of dispersions stabilized by surfactants. There are three main destabilization processes, gravity induced evolution, Ostwald ripening, and drops or bubble coalescence, which are analyzed separately. The discussion is restricted to the case of ...
the formation of the emulsion and its long-term stability [1–3]. Emulsions may be classified according to the nature of the emulsifier or the structure of the system. This is illustrated in Table 1.1. 1.1.1 Nature of the Emulsifier ThesimplesttypeisionssuchasOH− that can be specifically adsorbed on the emulsion droplet thus producing a ...
Jul 18, 2021 · Precipitation pH during the protein extraction process had a strong impact on the emulsion stability. RPP3 stabilized emulsions with higher stability in pHs close to neutral, whereas the opposite was found for RPP6.5, which stabilized more stable emulsions in acidic conditions.
Aug 3, 2013 · The document defines an emulsion as a mixture of two or more liquids that are normally immiscible. It then discusses the internal and external phases of emulsions, types of emulsions based on dispersed phase and size, advantages and disadvantages, identification tests, emulsifying agents, theories of emulsification, and factors that contribute to emulsion stability like interfacial tension.
In this review, we highlight and discuss the effects of interfacial properties on the major mechanisms governing the aging of emulsions: flocculation, coalescence and Ostwald ripening. The process of emulsification is also addressed, as it is well recognized that the adsorption properties of emulsif …
