Transitions between liquid crystalline phases investigated by dielectric and infra-red spectroscopies
Aleksandra Deptuch, Natalia Osiecka-Drewniak, Anna Paliga +5
The liquid crystalline 11OS5 compound, forming the nematic phase and a few smectic phases, is investigated by broadband dielectric spectroscopy and infra-red spectroscopy. The diel…
Selective reflection of light in glassforming ternary liquid crystalline mixtures
Aleksandra Deptuch, Zuzanna Zając, 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…
Crystal structure, magnetic properties and magnetocaloric performance of RERhIn (RE = Gd-Tm) compounds
Altifani Rizky Hayyu, Stanisław Baran, Aleksandra Deptuch +1
Polycrystalline samples of the RERhIn (RE = Gd--Tm) intermetallics have been investigated by means of X-ray diffraction (XRD) as well as by DC and AC magnetometric me…
Low-temperature structural study of smectic C* glass by X-ray diffraction
Aleksandra Deptuch, Marcin Kozieł, 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…
Glassforming liquid crystalline equimolar mixtures of MHPOBC and fluorinated compounds -- structural, optical, and dielectric properties
Aleksandra Deptuch, Anna Paliga, Anna Drzewicz +2
Three liquid crystalline equimolar mixtures are formulated, each containing the MHPOBC compound and the homolog from the 3FmHPhF6 series with m = 4, 5, and 6. The properties of the…
