Journal ArticleDOI
Ferroelectric-Ferroelastic Phase Transition in a Nematic Liquid Crystal.
Nerea Sebastián,Luka Cmok,Richard J. Mandle,Maria de la Fuente,Irena Drevenšek Olenik,Irena Drevenšek Olenik,Martin Čopič,Martin Čopič,Alenka Mertelj +8 more
TL;DR: It is shown that ferroelectric ordering of the molecules causes the formation of recently reported splay nematic liquid-crystalline phase, which drives an orientational ferroelastic transition via flexoelectric coupling.
Journal ArticleDOI
Dielectric, calorimetric and mesophase properties of 1′′-(2′,4-difluorobiphenyl-4′-yloxy)-9′′-(4-cyanobiphenyl-4′-yloxy) nonane: an odd liquid crystal dimer with a monotropic mesophase having the characteristics of a twist-bend nematic phase
Nerea Sebastián,David López,Beatriz Robles-Hernández,Beatriz Robles-Hernández,M. R. de la Fuente,Josep Salud,M. A. Perez-Jubindo,D. A. Dunmur,Geoffrey R. Luckhurst,D. J. B. Jackson +9 more
TL;DR: It is concluded that the low temperature mesophase exhibits the characteristics of a twist-bend nematic phase, and the nematic-to-isotropic phase transition has been exhaustively studied from the accurate evolution of the heat capacity and the static dielectric permittivity data.
Journal ArticleDOI
Twist, tilt, and orientational order at the nematic to twist-bend nematic phase transition of 1″,9″-bis(4-cyanobiphenyl-4'-yl) nonane: A dielectric, 2 H NMR, and calorimetric study
Beatriz Robles-Hernández,Nerea Sebastián,Nerea Sebastián,M. Rosario de la Fuente,David López,S. Diez-Berart,Josep Salud,M. Blanca Ros,D. A. Dunmur,Geoffrey R. Luckhurst,Bakir A. Timimi +10 more
TL;DR: The nature of the nematic-nematic phase transition in the liquid crystal dimer 1″,9″-bis(4-cyanobiphenyl-4'-yl) nonane (CB9CB) has been investigated using techniques of calorimetry, dynamic dielectric response measurements, and (2)H NMR spectroscopy.
Journal ArticleDOI
Splay Nematic Phase
Alenka Mertelj,Luka Cmok,Nerea Sebastián,Richard J. Mandle,Rachel R. Parker,Adrian C. Whitwood,John W. Goodby,Martin Čopič,Martin Čopič +8 more
TL;DR: In this paper, a transition from uniaxial to novel nematic phase characterized by a periodic splay modulation of the director is described, and the phase transition is weakly first order with a significant pretransitional behavior, which manifests as strong splay fluctuations.
Journal ArticleDOI
Mesophase structure and behaviour in bulk and restricted geometry of a dimeric compound exhibiting a nematic-nematic transition.
Nerea Sebastián,Maria-Gabriela Tamba,Ralf Stannarius,M. R. de la Fuente,Mirosław Salamończyk,Greta Cukrov,J. T. Gleeson,S. Sprunt,Antal Jakli,Christopher J. Welch,Ziauddin Ahmed,Georg H. Mehl,Alexey Eremin +12 more
TL;DR: The higher temperature nematic phase was found to exhibit an anomaly of the bend elastic constant similar to that of the dimers with N-Ntb phase sequence, and the physical properties of the low-temperature nematics phase are similar to those of the known Ntb materials.
