What Factors Influence Fickian Diffusion at the Nanoscale?
Several factors can influence Fickian diffusion in nanoscale systems:
1. Particle Size and Shape: Smaller particles have a higher diffusion coefficient due to their lower mass and reduced resistance to movement. 2. Medium Viscosity: The viscosity of the surrounding medium can significantly affect the diffusion rate. Higher viscosity leads to slower diffusion. 3. Temperature: Increasing the temperature generally increases the diffusion coefficient by providing more kinetic energy to the particles. 4. Surface Properties: The interaction between nanoparticles and the medium, including surface charge and hydrophobicity, can impact the diffusion process.
