Interfacial adsorption is a research area that focuses on the study of the adsorption of molecules at interfaces between two phases, such as solid-liquid, liquid-gas, or liquid-liquid interfaces. This area of research is important in various fields such as chemistry, materials science, and environmental science, as interfacial adsorption plays a crucial role in processes such as catalysis, surface modification, and environmental remediation. Researchers in this field aim to understand the mechanisms and thermodynamics of adsorption at interfaces, as well as to develop new materials and techniques to control and manipulate interfacial adsorption for various applications.
