Finally, for the dispersion of hydrophobic NPs in C8 no aggregation occurs even after 2500 ns, which is due to the larger barriers resulting from the stronger solvent domains organization around NPs in this system. Not only were no dimers formed, but no nanoparticles even entered the cutoff radius of another for calculating interactions. Hence, the contribution of the NP-NP interaction for the system energy was zero along the whole simulation (Figure ).
