This observation from the ab initio computations is in line with experimental results. Dong et al. have observed that for a Cs atom interacting with a surface coating of paraffin, the energy dissipation (≈ adsorption energy) is directly proportional to the square root of the relaxation rate or inversely proportional to the square root of relaxation time. In addition, the interaction with the cell wall coat is considered dominant over cell-wall dwell time; for example when comparing paraffin and OTS, and paraffin and mono-unsaturated alkene. 8
