Figure 5.

Temperature changes in dielectric constant derivatives of MBBA and its nanocolloids with BaTiO₃ nanoparticles. Concentrations are given in the plot. Dashed arrows indicate transitions between the isotropic liquid and nematic phases, and solid arrows indicate nematic–solid phase transitions. Values of $T_{I–N}$ and $T_{N–S}$ temperatures are given in Table 1. Dotted arrows indicate phase transition in the solid phase, with $T_{S1}, T_{S2}, { T}_{S3}$ phase transition temperatures. The dashed-dotted arrow (in grey) indicates the transformation within the nematic phase, associated with $T_{cross.}\approx 295.3 \mathrm{K}$.
