Interfacial Phenomena Overview

Principles

Definition

Interfacial phenomena is a fundamental concept and research field investigating the physical and chemical processes, properties, and behavior occurring at the boundaries between different phases of matter. This area of study focuses on the unique forces (such as surface and interfacial tension), structures, and dynamics present at these interfaces, which govern critical macroscopic phenomena like wetting, adhesion, emulsification, and heterogeneous catalysis, having significant implications across various scientific and engineering disciplines.

Diffuse-Interface Foundations era

Robert Evans [1], a central figure of the diffuse-interface foundations era, was associated with Baylor College of Medicine [3] and Columbia University [4]. His key contributions include Phase equilibria of fluid interfaces and confined fluids [7], Fluids in narrow pores: Adsorption, capillary condensation, and critical points [8], and Capillary condensation and adsorption in cylindrical and slit-like pores [9], which advanced gradient-based interfacial thermodynamics and provided a predictive link between microscopic density variations and macroscopic interfacial phenomena. P. Tarazona [2], a prominent figure connected with the University of Bristol [5] and Universidad Autónoma de Madrid [6], contributed to the development of interfacial thermodynamics during this era. His work on phase equilibria of fluid interfaces and confined fluids [7], fluids in narrow pores [8], and wetting transitions at models of a solid-gas interface [10] helped to generalize the diffuse-interface framework to descry wetting phenomena and interfacial phase transitions, establishing essential foundations for capillarity and wetting predictions in porous media.

Confinement and Phase-Field Dynamics era

Hong Li [1], affiliated with the University of Science and Technology of China [3] and the University of Wisconsin–Madison [4], anchors the confinement-driven interfacial literature of this era. Her 2002 paper, 'Super‐Hydrophobic Surfaces: From Natural to Artificial' [7], advances understanding of how surface morphology and chemistry influence wetting and capillary phenomena in confined geometries, a development that supported phase-field and density-functional modeling in this era. Yanlin Song [2], affiliated with East China University of Science and Technology [5] and Jilin University [6], contributes to the era through the paper 'Super‐Hydrophobic Surfaces: From Natural to Artificial' [7]. Song's involvement in 'Super‐Hydrophobic Surfaces: From Natural to Artificial' [7] highlights the cross-institutional trend of translating natural wetting concepts to artificial confinement contexts, informing experimental constraints and computational modeling in this era.

Engineered Patterned Interfaces era

Lei Jiang [1] is a pivotal author in this era, with affiliations at Beijing University of Chemical Technology [3] and Northwestern University [4], contributing to interfacial patterning and wetting control, as exemplified by Designing Superhydrophobic Porous Nanostructures with Tunable Water Adhesion [7]. His key contributions include Designing Superhydrophobic Porous Nanostructures with Tunable Water Adhesion [7], Spontaneous and Directional Transportation of Gas Bubbles on Superhydrophobic Cones [8], and Manipulating Bubbles in Aqueous Environment via a Lubricant-Infused Slippery Surface [9], advancing robust interfacial control, directional droplet and bubble transport, and lubricant-mediated slip on patterned interfaces. Gareth H. McKinley [2] is associated with MIT [5] and Stanford University [6] during this era, reflecting his contributions to droplet mobility on lubricant-impregnated surfaces [10]. This 2012 work [10] advanced understanding of interfacial friction and droplet mobility on engineered lubricant-infused and textured interfaces, informing the broader design of durable interfacial control strategies for patterned systems.
