Our results show that the excess entropy is smaller when larger particles are fixated in their position and smaller particles distributed in residual space (Figs. and) than when smaller particles are fixated in their position and larger particles are distributed in residual space (Figs, and). Also, the excess entropy is smaller when larger particles are adjacent to the wall and small particles are distributed in residual space (Figs. 3a) than when the small particles are fixated adjacent to the wall and larger particles are distributed in residual space (Figs. 3c). Lastly, comparing Figs. 3a and 3c with corresponding Figs. and show that the excess entropy is lower when particles of one type are fixated adjacent to the wall and particles of the other type are distributed in residual space. Because a portion of the excluded volume of particles resides outside of the box and that frees more space for other particles to gain configurational entropy.
