Special Issue Information

Dear Colleagues,

Liquid–fluid interfaces are ubiquitous, playing a central role in different aspects of industry, nature or life. This makes it necessary to deepen our understanding of the physicochemical behavior governing such interfaces. However, this is not always easy and must be analyzed from the impact of molecular and supramolecular species on the flows occurring within the interfacial region or on the thickness of the interface. Furthermore, the broken symmetry associated with the formation of a liquid–fluid interface can be used a platform for the assembly of innovative materials with reduced dimensionality, which can have an impact in different technological and industrial field, including food science, cosmetics, biology, oil recovery, electronic, drug delivery, detergency, and tissue engineering. Therefore, the study of the most fundamental aspect of liquid–fluid interfaces, and the control of their equilibrium properties and the dynamics processes occurring within the interface, are paramount to exploit the entire potential of interfacial systems in science and technology. This requires a multidisciplinary approach involving researchers from different areas: chemistry, physics, pharmacy, biophysics, medicine, engineering or materials science.

For the above reasons, this Special Issue is intended to provide a general approach to fundamental and applied aspects related to the study of systems involving liquid–fluid interfaces, with the aim of providing a comprehensive perspective on the current state of the research field. It is expected that this can help to close the gap between the most fundamental knowledge on fluid interface and the development of new applications based on it.

The Special Issue is open to reviews and research articles within, but not limited to, the following topics:

  • Complex fluids;
  • Langmuir/Gibbs films;
  • Equilibrium properties of liquid–fluid interfaces;
  • Confinement at liquid–fluid interfaces;
  • Interfacial rheology;
  • Interfacial flows;
  • Biomimetic layers;
  • Lung surfactant;
  • Particle-laden interfaces;
  • Polymer, surfactant, particles, and their mixtures at liquid–fluid interfaces;
  • Evaporation, spreading, and patterning (coffee-ring formation);
  • Emulsions and foams;
  • Liquid–fluid interfaces as a platform for the fabrication of nanomaterials;
  • Surface-sensitive techniques.

The 3D Carreau fluid flow through a porous and stretching (shrinking) sheet is examined analytically by taking into account the effects of mass transfer, thermal radiation, and Hall current. The model equations, which consist of coupled partial differential equations (PDEs), are simplified to ordinary differential equations (ODEs) through appropriate similarity relations. The analytical procedure of HAM (homotopy analysis method) is employed to solve the coupled set of ODEs. The functional dependence of the hydromagnetic 3D Carreau fluid flow on the pertinent parameters are displayed through various plots. It is found that the x-component of velocity gradient (f(η)) enhances with the higher values of the Hall and shrinking parameters (m,ϱ), while it reduces with magnetic parameter and Weissenberg number (M,We). The y-component of fluid velocity (g(η)) rises with the augmenting values of m and M, while it drops with the augmenting viscous nature of the Carreau fluid associated with the varying Weissenberg number. The fluid temperature θ(η) enhances with the increasing values of radiation parameter (Rd) and Dufour number (Du), while it drops with the rising Prandtl number (Pr). The concentration field (ϕ(η)) augments with the rising Soret number (Sr) while drops with the augmenting Schmidt number (Sc). The variation of the skin friction coefficients (Cfx and Cfz), Nusselt number (Nux) and Sherwood number (Shx) with changing values of these governing parameters are described through different tables. The present and previous published results agreement validates the applied analytical procedure. Full article
