Interfacial science is the study of the physical and chemical properties of interfaces, which are the boundaries between different phases or materials. This includes interfaces between solids, liquids, gases, and between different phases of matter. Interfacial science focuses on understanding the behavior and interactions of molecules and particles at these interfaces, as well as the effects of surface tension, adhesion, and other surface properties on the overall behavior of materials. Research in interfacial science has applications in a wide range of fields, including materials science, chemistry, biology, and nanotechnology. By studying these interfaces, researchers can develop new materials with specific properties or create new technologies for various applications.
