- Abstract:
- ... Formulated products represent a particular class of complex chemical products, and their design is typically based on experience and extensive experimentation. Although still at an early stage, and despite that their potential is not fully accessed and not fully used by the industry, computer-aided design (CAD) methods and tools offer many possibilities in the design of formulated products. The CA ...

- Abstract:
- ... Macroemulsions rendered stable by adsorbed colloidal particles are termed Pickering emulsions. If the volume fraction of dispersed phase exceeds around 0.75, the emulsions are named high internal phase Pickering emulsions abbreviated to HIPPEs, which present new properties and potential applications. We review here the recent progress in preparing and studying HIPPEs of both oil-in-water and water ...

- Abstract:
- ... Viscoelastic materials containing bubbles or drops are encountered in numerous application fields and are presently the object of much interest. The motion of bubbles and drops in these matrices can be significantly different than in Newtonian fluids. This review is restricted to the case of motion in quiescent fluids (or small Reynolds number) and small bubbles and drops that are not appreciably ...

- Abstract:
- ... This article discusses new concepts in macroscopically monophasic colloidal systems, where entropy is a major driving force for very subtle interactions and structuring. First, we show how microemulsion-similar structures can be achieved with hydrotropes. These aggregates are less defined in structure and of shorter lifetime than classical micelles but still potentially useful microheterogeneities ...

- Abstract:
- ... Interfacial rheology of adsorbed layers of surfactants, demonstrating the response of the interface to interfacial deformations, plays a key role in formation and stability of foams and emulsions. It also provides insights into complex surfactant systems in different applications, in particular, medical treatments and diagnostics. The response of the interface is mainly determined by the compositi ...

- Abstract:
- ... This work reviews the origins, similarities, measurement techniques, and differences of the solvation and nano-colloidal oscillatory structural forces in confined domains. With an increasing confinement, the particles’ structural transition changes from 2D random layering to 2D crystalline packing, as observed experimentally and revealed by the radial distribution function. The 2D in-layer structu ...

- Abstract:

It covers a wide range of phenomena, but in this review the main focus is on the surface structures formed from dilute solution in the presence of electrolyte and in more concentrated solutions. Their formation under those conditions are set in th ...

- Abstract:
- ... Wetting is fundamental to many technological applications that involve the motion of the fluid–fluid interface on a solid. While static wetting is well-understood in the context of thermodynamic equilibrium, dynamic wetting is more complicated in that liquid interaction with a solid phase, possibly on molecular scales, can strongly influence the macroscopic scale dynamics. The problem with continu ...

- Abstract:
- ... At its core, the outcome of the collision between air bubbles is determined by the hydrodynamic interaction forces, which in turn are strongly dependent on the tangential mobility of the gas–liquid interfaces. A clean gas–liquid interface is tangentially mobile, whereas the presence of surfactant contaminants can immobilise the interface. Bubbles with mobile surfaces coalescence much easier becaus ...

- Abstract:
- ... Investigation into the physics of foaming has traditionally been focused on aqueous systems. Non-aqueous foams, by contrast, are not well understood, but have been the subject of a recent surge in interest motivated by the need to manage foaming across industrial applications. In this review, we provide a comprehensive discussion of the current state-of-the-art methods for characterizing non-aqueo ...

We know little about the prevalence of nanoplastics and the risks they pose to the health of living organisms; recent studies of plastics in the environment have not significantly contributed information about this crucial topic.
