The properties of supramolecular aggregates cross several disciplines, embracing the
sciences of nature and joining theory, experiment, and application. There are few articles …

Measurements of optical refractive indices (ordinary and extraordinary), as a function of
temperature, are reported for the heavy water/SDS molar ratio Mw= 36, with a decanol/SDS …

Here, we propose that some aspects of the phase diagram of nematic lyotropic materials can
be put in a universal form. We will show that a simple combination of the order parameter …

We have discussed the stabilization of the biaxial nematic phase in lyotropic liquid crystals,
based on previously published articles. New mixtures were reported, as well as a detailed …

Biaxial nematic phases have been the subject of a long list of studies. In particular, they
were found for a few lyotropic micellar solutions. There is a debate in the literature on …

The optical characterization of uniaxial nematic liquid crystals gives basic information on its
birefringence and on the shape anisotropy of micelles in nematic lyotropic phases. In this …

Topological defects plays an important role in many physical processes ranging from
morphogenesis of phase transitions in condensed matter system to the response to surface …

Neste trabalho estudamos, no contexto de campo médio, modelos microscópicos que
possam descrever o comportamento termodinâmico das fases nemáticas em sistemas …

We analyze the effect of doping a binary mixture of uniaxial rod (R)-and plate (P)-like hard
parallelepipeds having equal volumes and conjugated aspect ratios γ R= 1/γ P= 5. Uniaxial …
