Pair potential (in units of ) for SSC-SSC, SSC-NP, and NP-NP interactions as a function of separation.
The orientational correlation between the SSC molecular long axis and the vector connecting the centers-of-mass of the SSC and the NP (shown schematically in the inset) as a function of separation between the SSC center-of-mass and the NP surface. The correlation is weighted by the NP-SSC pair distribution function.
(a) The local orientational order parameter for half-spherical shells containing approximately 50 SSCs as a function of distance from the shell to a nanoparticle surface compared to the order parameter in an equivalent volume in the pure SSC. (b) Same as (a) for fluctuations in the local orientational order parameter.
End-to-end vector autocorrelation function for SSCs whose center of mass is within of the surface of a NP for various. Also shown is the end-to-end vector autocorrelation function for SSCs in the pure nematogen phase. Time is in reduced units.
The PMF (a) and matrixed-induced force (b) between a pair of small and large NPs in the dense isotropic phase of SSCs as a function of separation between the NP surfaces. The matrix induced forces are directly obtained by numerical derivatives from PMF and errors are magnified by this process, resulting rough curves but qualitatively reflect the repulsion and attraction part of the PMF curve.
Orientational order of SSCs in the volume between NPs for various interparticle distances. The cylindrical volume formed between two NPs of the diameter D and surface separation is illustrated by the grey region. The inset shows the distribution of the number of SSC in between two large NPs at a separation of .
