PT symmetric Floquet topological phase
(Springer, 2015)In this paper, we study the existence of Floquet topological insulators for PT symmetric non-Hermitian Hamiltonians. We consider an array of waveguide in 1D with periodically changing non-Hermitian potential and predict ... -
Removal of lead (II) and nickel (II) ions from aqueous solution using activated carbon prepared from rapeseed oil cake by Na2CO3 activation
(Springer, 2015)In this study, rapeseed oil cake as a precursor was used to prepare activated carbons by chemical activation with sodium carbonate (Na2CO3) at 600 and 800 A degrees C. The activated carbon with the highest surface area of ... -
Semi-synthetic biotin imprinting onto avidin crosslinked gold-silver nanoparticles
(Springer, 2012)This study is a different and new application of molecular imprinted polymers (MIPs) based on sensor technologies. In this study, semi-synthetic biotin imprinted polymeric shell has been decorated onto the surface of avidin ... -
Single-oscillator model and determination of optical constants of spray pyrolyzed amorphous SnO2 thin films
(Springer, 2007)Amorphous SnO2 thin films have been deposited using different spraying times via the spray pyrolysis method. The structure of the films was analyzed by X-ray diffraction and the results obtained showed that the structure ... -
Structural, Electrical, and Magnetic Properties of High-Temperature-Sintered La1-xNaxMnO3 (0.05 <= x <= 0.35) Compounds
(Springer, 2015)The structural, electric, and magnetic properties of La1-xNaxMnO3 (0.05 <= x <= 0.35) compounds have been investigated. The compounds were prepared by a standard sol-gel method then sintered at 1400 degrees C for 24 h. The ... -
A study of photomodulated reflectance on staircase-like, n-doped GaAs/Al (x) Ga1-x As quantum well structures
(Springer, 2012)In this study, photomodulated reflectance (PR) technique was employed on two different quantum well infrared photodetector (QWIP) structures, which consist of n-doped GaAs quantum wells (QWs) between undoped Al (x) Ga1-x ... -
Study of thermal and CH4 adsorption properties
(Springer, 2015)In this study, the adsorption of methane (CH4) on zeolite from Sivas-Yavu region of Turkey and on forms treated with 1 M heavy metal nitrate solutions (AgYZ, Cu YZ and FeYZ) and 1, 3 and 5 M HCl solutions (HYZ, 3HYZ and ... -
Synergistic thallium and iodine memory-based cryogel traps for removing thallium and iodine ions
(Springer, 2017)Both recovery and effective removing of radioactive thallium and iodine are important subject to protect human health and the environment. In this study, we have studied synergistic and cost-effective cryogel based sorbents ... -
Synthesis and Photodiode Characterization of Novel Twisted Carbazole Derivatives with 1,3,5-Benzene Core
(Springer, 2018)In this study, considering the information given in the literature the Ullman and Suzuki-Miyaura coupling reactions were carried out using carbazole, 1,3,5 tribromo benzene and aryl boronic acid. The synthesized novel ... -
Thermal and SO2 adsorption properties of some clays from Turkey
(Springer, 2011)Thermal and structural properties of three clays (sepiolite and two kaolinites) from Turkey were studied by thermal analysis (TG-DTA), X-ray diffraction (XRD), X-ray fluorescence (XRF), Fourier transform infrared (FT-IR), ... -
Thermal behavior and immersion heats of selected clays from Turkey
(Springer, 2009)Four clays (two bentonites and two kaolinites) from Turkey were investigated by X-ray diffraction (XRD), thermal analysis (DTA/TG-DSC) and surface area measurement techniques. Mineralogically bentonite samples were ... -
