Competing crystallization pathways and cold crystallization kinetics in 10OS5 liquid crystal
Aleksandra Deptuch, MirosÅawa D. Ossowska-ChruÅciel, Janusz ChruÅciel +1
The liquid crystalline 4-pentylphenyl-4'-decyloxythiobenzoate is investigated in various temperature programs for determination of crystallization kinetics and glassforming propert…
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…
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…
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…
Crystal structure, magnetic properties and magnetocaloric performance of RERhIn (RE = Gd-Tm) compounds
Altifani Rizky Hayyu, StanisÅaw 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 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…
