![]() Pickering emulsion biomaterials drug delivery microspheres nanoparticles. As pointed by Wei et al., the Pickering emulsion system is a type of power-law fluid that follows Ostwaldde Waele’s relationship. The values of H E and H e for different samples were measured via visual analysis of the photographs of the samples using ImageJ software. For all Pickering emulsions, the apparent viscosity () gradually decreased with an increase in the shear rate from 0.1 to 10 s 1, indicating the shear-thinning behavior of all emulsions. In this article, we give an overview of Pickering emulsions, focusing on some kinds of solid particles commonly serving as emulsifiers, three main types of products from Pickering emulsions, morphology of solid particles and as-prepared materials, as well as applications in different fields. where H E is the total emulsion height and H e is the serum layer height. Pickering emulsions can be applied in a wide range of fields, such as biomedicine, food, fine chemical synthesis, cosmetics, and so on, by properly tuning types and properties of solid emulsifiers. Besides, they are more biocompatible when solid particles employed are relatively safe in vivo. Substituting solid particles for traditional surfactants, Pickering emulsions are more stable against coalescence and can obtain many useful properties. Sand pack displacement experiments showed a high potential of oil recovery increase while practical implementation of the proposed compositions.Pickering emulsion, a kind of emulsion stabilized only by solid particles locating at oil-water interface, has been discovered a century ago, while being extensively studied in recent decades. To this end, experiments were performed to determine the zeta potential, particle size distribution of the dispersed phase, rheological properties at different temperature conditions. Coalescence in concentrated Pickering emulsions under shear. Consequently, the exploration of Pickering emulsions for biphasic catalysis is a hot topic in the study of applications of Pickering emulsions. Figure 4: Evolution of diameter distribution through coalescence examined by Monte Carlo simulation. The impact of nanoparticles structure was evaluated within the frame of emulsion stabilization. Pickering emulsions are an ideal platform for biphasic catalysis because of their enhanced stability, large interfacial area, facile product separation, and easy catalyst recycling. In this research Pickering emulsions composition stabilized by SiO2 nanoparticles had been obtained. Pickering emulsion, a kind of emulsion stabilized only by solid particles locating at oil-water interface, has been discovered a century ago, while being extensively studied in recent decades. One of the promising technologies in this regard is so-called Pickering emulsions application. This issue requires development of new emulsion types which overcome these drawbacks. However, this technology has serious limitations for implementation in high temperature reservoirs. One of the most promising and effective technologies of mentioned methods is “oil-in-water” inverse emulsions. In this case, another type of emulsion can form that is mainly stabilized by the presence of a surfactant layer at the surface of the drops. Pickering emulsion, a kind of emulsion stabilized only by solid particles locating at oilwater interface, has been discovered a century ago, while being extensively studied in recent decades. Indeed, it is commonly admitted that is directly linked to the type of the stabilized emulsion (O/W, W/O or multiple) 24. Such Pickering emulsions are stabilized by solid particles only.69 If a surfactant is also present, the particle wetting preference can be changed and possibly the particles will not adsorb. The majority of implementations are occupied by physical and chemical EOR methods based on the injection of chemical compounds into formations. The emulsion type mainly follows the empirical Finkle rule, which is the equivalent for Pickering emulsions of the Bancroft rule used for emulsions stabilized by surfactants 126, 129. In this context, Enhanced oil recovery (EOR) techniques, represented by a wide range of modern technologies, are becoming more and more important year by year. With increasing number of mature oil fields, exploitation of these reserves becomes an important task. ![]() Today, the amount of residual oil in the world averages more than 70% of the original geological reserves.
