1,3-Dimethyl-5-(3,4,5-tris(alkoxy)benzoyl) barbituric acid derivatives and their liquid crystalline difluoroboron complexes: Synthesis, characterization and comparative investigations of mesomorphic, thermotropic and thermo-morphologic properties
(Elsevier, 2014)A series of 1,3-dimethyl-5-(3,4,5-tris(alkoxy)benzoyl) barbituric acid derivatives 1a-4a with various chain length were synthesized by our group for the first time through the addition of 1,3-dimethyl barbituric acid to ... -
The effect of disorder on integer quantized Hall effect
(Elsevier, 2012)We study the effects of disorder on the integer quantized Hall effect within the screening theory, systematically. The disorder potential is analyzed considering the range of the potential fluctuations. The short-range ... -
Electrical measurements of Hg1 - xMnxTe films grown by metalorganic vapour phase epitaxy
(Elsevier, 1996)Preliminary electrical measurements of mercury manganese telluride (MMT) films, grown by metalorganic vapour phase epitaxy (MOVPE), are reported. The epitaxial films were grown on insulating (100)GaAs substrates with a ... -
Electronic aspects of the martensitic transition in Ni-Mn based Heusler alloys
(Elsevier, 2007)The martensitic transformation temperature Ms depends linearly on the valence electron concentration for Ni-Mn-X Heusler systems where X is a group III-group V element. However, the slopes of the linearity are different ... -
Enhancing the c-TiO2 based perovskite solar cell performance via modification by a serial of boronic acid derivative self-assembled monolayers
(Elsevier, 2017)Morphological control of MAPbI(3) crystal growth is one of the most important factor to fabricate high efficient perovskite solar cells. Herein, different boronic acid derivative self-assemble monolayers were used for ... -
Lyotropic liquid crystalline hexagonal mesophase. Thermo-morphologic and magneto-morphologic transformations, electrical conductivity and optical refractive properties: Effect of optically active compounds
(Elsevier, 2020)Mesophase chirality in lyotropic liquid crystalline hexagonal E mesophase, which is formed by the anisometric micelles with quasi-infinite length, was studied. Effect of the optically active dopants {tartaric acid (TA) and ... -
Optical refracting properties, birefringence and order parameter in mixtures of liquid crystals: Direct smectic A - Isotropic and reverse isotropic - Smectic A phase transitions
(Elsevier, 2022)Due to the physical anisotropic and self-assembling nature, liquid crystalline materials holdvery important place in theoretical, experimental and applied physics. Besides, liquid crystals are important materials as working ... -
Study of mesomorphism, thermotropic properties and pitch in new chiral smectogenic imine compounds
(Elsevier, 2015)We report the thermotropic, thermo-morphologic and structural properties of four homologs of (S)-5-alkyloxy-2-[{4-(2-methylbutoxy)phenylimino}methyl]phenol liquid crystalline salicylaldimine compounds, which are firstly ... -
Temperature dependent symmetry to asymmetry transition in wide quantum wells
(Elsevier, 2015)Quasi-two dimensional electron systems exhibit peculiar transport effects depending on their density profiles and temperature. A usual two dimensional electron system is assumed to have a 6 like density distribution along ... -
Texture transformations and thermo-optical properties of nematic mesogen at nematic-isotropic liquid phase transition
