Journal ArticleDOI
Critical behaviour in liquid-crystalline phase transitions: a comparative study of 9OCB in bulk and Anopore membranes
S. Diez-Berart,David López,M. R. de la Fuente,Josep Salud,M. A. Perez-Jubindo,Daniele Finotello +5 more
TL;DR: In this article, the authors present an experimental study on the critical behaviour of the nematic-toisotropic (N-I) and smectic A-to-nematic (SmA-N) phase transitions of the liquid crystal 4-nonyloxy-4′-cyanobiphenyl (9OCB) liquid crystal.
Journal ArticleDOI
Tests of the tricritical point in the SmA-to-N phase transition of binary mixtures of butyloxybenzylidene octylaniline and hexyloxybenzylidene octylaniline
TL;DR: In this article, a significant difference between the experimental Landau tricritical point (LTCP) in the Sm A-to-N phase transition in binary mixtures of butyloxybenzylidene octylaniline (4O.8 + 6O.
Journal ArticleDOI
Dispersion of γ-Alumina Nano-Sized Spherical Particles in a Calamitic Liquid Crystal. Study and Optimization of the Confinement Effects
S. Diez-Berart,David López,Nerea Sebastián,Maria de la Fuente,Josep Salud,Beatriz Robles-Hernández,M. A. Perez-Jubindo +6 more
TL;DR: Results indicate that the confinement of liquid crystals by means of γ-alumina nanoparticles could be optimum for liquid crystal-based electrooptic devices.
Journal ArticleDOI
Molecular dynamics of a binary mixture of twist-bend nematic liquid crystal dimers studied by dielectric spectroscopy.
Beatriz Robles-Hernández,Nerea Sebastián,Nerea Sebastián,Josep Salud,S. Diez-Berart,David Dunmur,Geoffrey R. Luckhurst,David López,M. Rosario de la Fuente +8 more
TL;DR: It is shown that the dielectric spectra of the mixture reflect the different molecular dipole properties of the components, resembling in the present case the characteristic dielectra of nonsymmetric dimers.
Journal ArticleDOI
Two glass transitions associated to different dynamic disorders in the nematic glassy state of a non-symmetric liquid crystal dimer dopped with gamma-alumina nanoparticles
S. Diez-Berart,David López,Josep Salud,J.A. Diego,Jordi Sellarès,Beatriz Robles-Hernández,María Rosario De la Fuente,María Blanca Ros +7 more
TL;DR: In this paper, the nematic glassy state of the non-symmetric LC dimer α-(4-cyanobiphenyl-4'-yloxy)-ω-(1-pyrenimine-benzylidene)-4'-oxy) undecane is studied by means of calorimetric and dielectric measurements.
