Ternary liquid crystalline mixture showing broad antiferroelectric smectic C* and glassy hexatic smectic X* phases
Aleksandra Deptuch, Anna Drzewicz, Marcin Piwowarczyk +4
A ternary liquid crystalline mixture was designed to obtain a tilted hexatic smectic phase in the glassy state. Structural, electro-optic, and dielectric properties of the mixture…
Interpretable liquid crystal phase classification via two-by-two ordinal patterns
Leonardo G. J. M. Voltarelli, Natalia Osiecka-Drewniak, Marcin Piwowarczyk +4
Liquid crystal textures encode rich structural information, yet mapping these images to mesophase identity remains challenging because visually similar patterns can arise from dist…
Selective reflection of light in glassforming ternary liquid crystalline mixtures
Aleksandra Deptuch, Zuzanna ZajÄ c, Marcin Piwowarczyk +4
Two ternary liquid crystalline mixtures are formulated and investigated by differential scanning calorimetry, polarizing optical microscopy, X-ray diffraction, and broadband dielec…
Low-temperature structural study of smectic C* glass by X-ray diffraction
Aleksandra Deptuch, Marcin KozieÅ, Marcin Piwowarczyk +2
The liquid crystalline compound, forming the glass of the smectic C* phase, is investigated by the X-ray diffraction in the 18-298 K range. The characteristic distances within…
Crystallization kinetics of equimolar liquid crystalline mixture and its components
Aleksandra Deptuch, Anna Paliga, Anna Drzewicz +3
The new equimolar mixture comprises liquid crystalline compounds MHPOBC and partially fluorinated 3F2HPhF6. The phase sequence of the mixture is determined by differential scanning…
