Oberflächentransport

Oberflächentransport refers to the movement of particles or substances along a surface. This phenomenon is crucial in various scientific disciplines, including chemistry, physics, geology, and materials science. It encompasses a range of processes, such as diffusion, adsorption, and desorption. In chemistry, surface transport is vital for heterogeneous catalysis, where reactants move across the surface of a catalyst to undergo chemical reactions. The rate and mechanism of surface transport depend on factors like surface properties, temperature, pressure, and the nature of the transported species. For instance, in solid-state diffusion, atoms move through the crystal lattice of a solid, which can be considered a form of surface transport at the atomic level. Geologists study surface transport in processes like erosion and sediment transport, where materials are moved by wind, water, or ice. Understanding surface transport is essential for designing materials with specific properties, optimizing chemical processes, and predicting environmental changes.
