We present results of the electro-optical effect in 90 twisted nematic cells of pristine and
doped liquid crystals under an applied dc voltage. The doped cells were fabricated with a …

Palladium nanoparticles covered with liquid-crystal molecules were prepared by UV
irradiation of an alcohol solution of palladium (II) acetate in the presence of liquid-crystal …

Recent experimental and theoretical efforts have focused on using liquid-crystal systems as
a test bed for understanding the statistical mechanics of quenched random disorder. In …

High-resolution calorimetric studies have been made of the liquid crystal phase transitions
for several dispersions of 70-Å-diam silica spheres (aerosil) in octylcyanobiphenyl (8CB) as …

We study smectic liquid crystals in random environments, eg, aerogel. A low-temperature
analysis reveals that even arbitrarily weak quenched disorder (ie, arbitrarily low aerogel …

The static and dynamic aspects of (4− n− heptyl− 4′− cyanobiphenyl)(7CB) perturbed by
the dispersion of 70-Å-diameter hydrophilic silica aerosil spheres have been investigated …

A photopyroelectric technique has been applied to the study of specific heat and thermal
conductivity of homeotropically aligned mixtures of small quartz spheres (aerosil) and …

This chapter considers basic modulation measurements, including calorimetry under high
pressures. For our purpose, it is convenient to divide the whole temperature range of …

We have studied a composite system formed by a nematic thermotropic liquid crystal in
which small silica particles have been dispersed. The colloids are aggregated and exert a …

High-resolution ac calorimetric studies show that the dispersion of 70-Å-diameter hydrophilic
silica spheres (aerosils) has a substantial effect on several liquid-crystal transitions in …
