Journal ArticleDOI
Nanoparticle-induced widening of the temperature range of liquid-crystalline blue phases
Eva Karatairi,Brigita Rožič,Zdravko Kutnjak,Vassilios Tzitzios,George Nounesis,George Cordoyiannis,Jan Thoen,Christ Glorieux,Samo Kralj +8 more
TL;DR: Systematic high-resolution calorimetric studies reveal thatblue phase III is effectively stabilized in a wide temperature range by mixing surface-functionalized nanoparticles with chiral liquid crystals, yielding a robust method to stabilize blue phases, especially blue phase III.
Journal ArticleDOI
Temperature-Driven Mixing-Demixing Behavior of Binary Mixtures of the Ionic Liquid Choline Bis(trifluoromethylsulfonyl)imide and Water
Peter Nockemann,Koen Binnemans,Ben Thijs,Tatjana N. Parac-Vogt,Klaus Merz,Anja-Verena Mudring,Preethy Chirukandath Menon,Ravindran Nair Rajesh,George Cordoyiannis,Jan Thoen,Jan Leys,Christ Glorieux +11 more
TL;DR: The thermophysical properties of water-choline bistriflimide binary mixtures were studied by a photopyroelectric technique and by adiabatic scanning calorimetry (ASC).
Journal ArticleDOI
Different modulated structures of topological defects stabilized by adaptive targeting nanoparticles
George Cordoyiannis,Venkata Subba Rao Jampani,Samo Kralj,Surajit Dhara,Vassilios Tzitzios,Georgia Basina,George Nounesis,Zdravko Kutnjak,Chandra Shekhar Pati Tripathi,Patricia Losada-Pérez,Dalija Jesenek,Christ Glorieux,Igor Muševič,Aleksander Zidanšek,Aleksander Zidanšek,Heinz Ameinitsch,Jan Thoen +16 more
TL;DR: In this article, it was shown that the twist-grain boundary phase in a chiral liquid crystal is driven by direct interactions between surface-functionalized CdSe quantum dots and screw dislocations.
Journal ArticleDOI
Investigations of phase transitions in liquid crystals by means of adiabatic scanning calorimetry
TL;DR: In this paper, a high-resolution adiabatic scanning calorimetric technique has been proposed to distinguish between first-order and second-order phase transitions in addition to rendering highresolution information on fluctuations-induced pretransitional specific heat capacity behaviour.
Journal ArticleDOI
Effects of magnetic nanoparticles with different surface coating on the phase transitions of octylcyanobiphenyl liquid crystal.
TL;DR: The impact of magnetic nanoparticles with different surface coating upon the isotropic-to-nematic and nematic- to-smectic- A phase transitions of the liquid crystal octylcyanobiphenyl is explored by means of high-resolution adiabatic scanning calorimetry, and a shrinkage of the nematic range is observed.
