Analogy between periodic patterns in thin smectic liquid crystal films and the intermediate state of superconductors
Zappone, Bruno; Mamuk, Atilla Eren; Gryn, Iryna; Arima, Valentina; Zizzari, Alessandra; Bartolino, Roberto; Petschek, Rolfe (Natl Acad Sciences, 2020)Spontaneous breaking of symmetry in liquid crystal (LC) films often reveals itself as a microscopic pattern of molecular align-ment. In a smectic-A LC, the emergence of positional order at the transition from the nematic ... -
A comparative study on electrospun fibers of cyanobiphenyl liquid crystal homologues
Mamuk, Atilla Eren (TAYLOR & FRANCIS INC, 2023)Cyanobiphenyl homologues are important liquid crystals to use in some applications since they exhibit intrinsic properties in a certain temperature interval including room temperature. Recently, generating composites with ... -
Electrochemical Properties of Coumarin 500 Encapsulated in a Liquid Crystal Guided Electrospun Fiber Core and Their Supercapacitor Application
Mamuk, Atilla Eren; Koçak, Çağdaş; Aslan, Sema (AMER CHEMICAL SOC, 2022)Here, we first report a study on coumarin 500 and liquid crystal including polyacrylonitrile nanofibers in terms of synthesis, characterizations, and supercapacitor performances. SEM, POM, FTIR, and DSC measurements showed ... -
Electrospun fibers of liquid crystal mixtures
Koçak, Çağdaş; Mamuk, Atilla Eren; Demirci Dönmez, Çiğdem Elif; Poyraz, Mehmet (SPRINGER, 2022)Electrospinning is a powerful and promising technique in production of nano-materials namely nano-fibers. Nano-sized materials show properties apart from their macroscopic/bulk sizes, and enable us to fabricate materials ... -
Investigation of the viscoelastic properties of 4-propoxy-biphenyl-4-carbonitrile
Özden, Pınar; Mamuk, Atilla Eren; Avcı, Nejmettin (Taylor & Francis Ltd, 2019)We report on the temperature-dependent measurements of dielectric permittivity, birefringence, elastic constants and rotational viscosity for 4-propoxy-biphenyl-4-carbonitrile in the nematic region. The temperature dependence ... -
Peculiarities of thermo-morphologic and thermotropic transformations of heterophase regions: nematic <-> isotropic phase transition in 4-n-Alkyl-4 '-cyanobiphenyl mesogens
Mamuk, Atilla Eren; Nesrullajev, Arif (Natl Inst Optoelectronics, 2019)Important peculiarity of phase transitions in liquid crystalline materials is availability of the heterophase regions, in which low temperature and high temperature phases simultaneously take place. In this work, peculiarities ... -
Production and characterization of liquid crystal/polyacrylonitrile nano-fibers by electrospinning method
Mamuk, Atilla Eren; Koçak, Çağdaş; Demirci Dönmez, Çiğdem Elif (Springer Link, 2021)We present that high birefringent nematic liquid crystal, 4-n-pentyl-4'-cyanobiphenyl, was incorporated into the polyacrylonitrile precursor which has a strong polar cyano group so as to produce electrospun nano-fibers, ... -
Refractive and birefringent properties and order parameter of nematic liquid crystal at the direct and reverse nematic <-> isotropic liquid phase transition
Mamuk, Atilla Eren; Nesrullajev, Arif (Natl Inst Optoelectronics, 2016)Temperature dependences of the refractive indices, birefringence and molecular polarizability in large temperature interval and especially in the region of the direct nematic mesophase - isotropic liquid (for the heating ... -
Refractive and birefringent properties of 4-alkyl-4 '-oxycyanobiphenyls at direct and reverse phase transitions
Mamuk, Atilla Eren; Nesrullajev, Arif; Mukherjee, Prabir K. (Taylor & Francis Ltd, 2017)Studies of temperature behavior of the mean refractive index, ordinary and extraordinary refractive indices, and birefringence have been carried out for three nematogens. The thermo-morphologic properties of the biphasic ...
