  The pretransitional behavior of dodecylcyanobiphenyl (12CB)
(isotropic-smectic-A-solid mesomorphism) with $d = 50$ nm $BaTiO_3$
nanoparticles (NPs) linked the cubic phase was monitored via temperature
studies of dielectric constant. Tests were carried out in the isotropic, liquid
crystal mesomorphic and solid phases. For each phase transition the same value
of the critical exponent $\alpha=0.5$ was obtained, including nanocolloids. All
phase transitions show the weakly discontinuous nature. The temperature metric
of the discontinuity dT notably decreases when adding nanoparticles. The
addition of nanoparticles first decreases the dielectric constant by approx.
$50%$ in comparison with pure 12CB, but already for a concentration $x = 0.4%%
NPs an increase over $50%$ takes place. It is notable that for the latter
concentration unique hallmarks of the pretransitional effect emerge also for
the solid-mesophase transition. All thease indicate the important impact of
nanoparticles on multimolecular mesoscale fluctuations.
