The effects of the anionic azo dye Sunset Yellow on the stabilization of lyotropic uniaxial and
biaxial nematic phases and on the uniaxial to biaxial phase transitions were studied. The …

In the present study, the interactions of the anionic azo dye Sunset Yellow with
dodecylalkylammonium bromide (DAABr) surfactants in lyotropic mixtures have been …

Lyotropic nematic phase properties of novel mixtures of dodecyltrimethylammonium bromide
(DTMABr)/1-dodecanol (DDeOH)/water, doping with anionic azo dyes (amaranth and …

Lyotropic quaternary mixtures of some tetradecylalkylammonium bromide surfactants were
prepared to examine the effect of the size of the surfactant head group on the stabilization of …

Lyotropic liquid crystals exhibiting nematic phases were obtained from the mixtures
potassium laurate/alkali sulfate salts (M 2 SO 4)/1-undecanol (UndeOH)/water and sodium …

Guest–host liquid crystal displays have been widely utilised because of their many
advantages such as colour, wide viewing angle and high brightness. For practical guest …

Lyotropic mixtures including different sodium salts of Hofmeister anions were studied in
order to investigate the effect of these anions on the existence of biaxial nematic phase and …

Lyotropic quaternary mixtures of potassium alkanoates (KC x) and sodium alkyl sulphates
(NaC x S), where x is the number of carbon atoms in their alkyl chains, were prepared to …

The phase behaviour of N, N-dialkyl-N, N-dimethyl ammonium bromide double chain
surfactants was investigated by polarization microscopy, 2H-NMR spectroscopy, and surface …

Amino acid-based surfactants were used as the main surfactants to prepare new lyotropic
mixtures presenting three nematic phases. One of them is biaxial (NB), and the two others …
