Mesogenic materials exhibit a multitude of transitions involving new phases. Studies of
these phases are of importance in a wide range of scientific fields and as such have …

Smectic membranes are perfect model systems for studying low-dimensional phase
transitions and the associated fluctuations. During the last two decades we have seen …

In this article we investigate the complexity of the molecular architectures of liquid crystals
based on rod-like mesogens. Starting from simple monomeric systems founded on …

A theory is presented for the successive sixfold Fourier components, C 6 n, in the
bondorientational order in the neighborhood of asmectic− A− hexatic− B phase transition …

During the last couple of decades an impressive amount of calorimetric results has been
obtained, in many cases resulting in a better understanding of several phase transitions in …

For many decades, the lamellar liquid crystal phases with the general label 'smectic'were
considered to be quite mysterious. However, developments in theories of melting in two …

Ever since the hexatic phase was proposed more than 14 years ago in the context of two-
dimensional melting theory, the concept of hexatic order has offered unique insight into the …

High temperature resolution measurements of thermal conductivity, thermal diffusivity, and
specific heat, with simultaneous polarized light visual inspection of the sample, have been …

Thermal and structural studies have been performed on thin films of n-heptyl-4'-n-
pentyloxylbiphenyl-4-carboxylate (75OBC). Similar to 65OBC, a surface hexatic phase is …

A high-sensitivity ac calorimeter system has been developed to investigate the temperature
variation of the heat capacity from free-standing liquid-crystal films. We have observed a …
