Surface interactions refer to the processes that occur at the interface between a solid surface and a gas or liquid. These interactions can involve the adsorption of molecules onto the surface, the diffusion of molecules across the surface, and the reaction of molecules with the surface. Surface interactions are important in many scientific and engineering fields, including materials science, catalysis, corrosion, and biophysics. Understanding and controlling surface interactions is crucial for designing new materials, optimizing chemical reactions, and developing new technologies. Research in surface interactions often involves experimental techniques such as surface analysis, microscopy, and spectroscopy, as well as theoretical modeling and simulation. By studying the behavior of molecules at surfaces, researchers can gain insights into the fundamental processes that govern the behavior of materials and chemical systems.
