Stochastic Adsorption of Diluted Solute Molecules at Interfaces

  title={Stochastic Adsorption of Diluted Solute Molecules at Interfaces},
  author={Jixin Chen},
Here an analytical solution of Fick’s 2nd law is used to predict the diffusion and the stochastic adsorption of single diluted solute molecules on flat and patterned surfaces. The equations are then compared to the results of several numerical Monte Carlo simulations using a random walk model. The 1D diffusion simulations clarify that the dependence of the solute-surface collision rate on the observation-time (measurement time resolution) is because of the multiple collisions of the same…
