Interfacial research refers to the study of interfaces between different materials or phases, such as liquid-liquid, liquid-solid, or gas-solid interfaces. This research area often involves investigating the physical and chemical properties of these interfaces, as well as understanding the interactions between the materials at the interface. Interfacial research is important in various fields, including material science, chemistry, biology, and nanotechnology, as it plays a crucial role in determining the properties and behavior of materials and their interactions with their environment. This research can lead to the development of new materials, technologies, and applications in various industries.
