Asılı ve tek damla yöntemiyle liyotropik sıvı kristallerde yüzey gerilimlerinin belirlenmesi
Özden, Pınar; Avcı, Nejmettin (2017)Liyotropik sıvı kristaller kimyasal temizleyicilerden organik sıvılara kadar pek çok bileolu şturmaktadır. Kolloidal özelikleri nedeniyle bu malzemelerin yüzey gerilimlerinin belirlenmesi uygulama alanları için büyük önem ... -
Comparative investigations of the thermotropic and optical refractive properties in micellar isotropic phase and nematic-calamitic mesophase of hexadecyltrimethyl ammonium bromide/water and hexadecyltrimethyl ammonium bromide/water/1-decanol lyotropic liquid crystalline systems
Özden, Pınar; Nesrullajev, Arif (Springer, 2015)We report the thermotropic properties and measurements of the temperature and concentration dependences of the refractive index in isotropic micellar L (1) phase and nematic-calamitic N (C) mesophase of the hexadecyltrimethyl ... -
Electrical and photoresponse properties of metal–polymer–semiconductor device with TMPTA interface material
Özden, Pınar; Özden, Şadan; Pakma, Osman; Özenç, Mehmet Emin; Avcı, Nejmettin; Afşin Kariper I. (Springer, 2023)is study presents the pioneering fabrication of a metal–polymer–semiconductor (MPS) device, where trimethylolpropane triacrylate (TMPTA) was employed as the interface material for the first time. TMPTA offers significant ... -
The electrical characterization of metal–insulator–semiconductor device with β-naphthol orange interface
Özerden, Enise; Özden, Pınar; Afşin Kariper I.; Pakma, Osman (Springer, 2022)his study was formed by the β-naphthol orange/p-Si metal–insulator–semiconductor (MIS) structure by obtaining β-naphthol orange on the p-Si surface using the sol–gel and spin-coating techniques. FTIR, EDX, and NMR analyzes ... -
Investigation of Phase States, Thermo-Morphologic, Magneto-Morphologic and Refractive Properties of Mesophases in Dodecyltrimethyl Ammonium Bromide - Water Lyotropic Liquid Crystalline System
Nesrullajev, Arif; Özden, Pınar (Carl Hanser Verlag, 2016)We report the phase states in dodecyltrimethyl ammonium bromide/water (DDTMABr-H2O) lyotropic liquid crystalline system. The temperature-concentration phase diagram of this system has been determined. Isotropic micellar ... -
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 ... -
Phase states and thermomorphologic, thermotropic, and magnetomorphologic properties of lyotropic mesophases: Sodium lauryl sulphate-water-1-decanol liquid-crystalline system
Özden, Pınar; Nesrullajev, Arif; Oktik, Şener (Amer Physical Soc, 2010)Phase states in sodium lauryl sulphate-water-1-decanol lyotropic liquid-crystalline system have been investigated for different temperature ranges. The dependence of triangle phase diagram types, phase boundaries, and ...
