Synthesis, Structure, and Electrical Properties of New Homo and Heteronuclear Schiff Base Copper(II) and Nickel(II) Complexes

In this study, the new Schiff base ligands N,N '-bis[(1Z,2E)-1-(4-methylphenyl)-2-(hydroxyimino)-1-phenylethylidene]-4-methylbenzene-1,2-diamine and N,N '-bis[(1Z,2E)-1-(4-chlorophenyl)-2-(hydroxyimino)ethylidene]-4-methylbenzene-1,2 diamine have been synthesized. Their metal complexes with copper and nickel have been formed and characterized by FT-IR, UV-Vis, NMR, LC/MS-MS spectra, molar conductivity, magnetic susceptibility, elemental analysis, ICP-OES, and thermogravimetric analysis. The complexes demonstrate semiconducting features.Pamukkale University [2015HZL014]This study has been supported by Pamukkale University (grant nos. 2015HZL014

Investigation of electrical and structural properties of in-doped CdTe/CdS thin-film solar cells produced by E-beam techniques

In the current study, the electron beam (e-beam) evaporation deposition technique was utilized to examine the effect of annealing on the structural and electrical properties of In-doped CdTe/CdS thin-film solar cells. Thin-film solar cells were deposited onto the ITO-coated glass substrate with the e-beam technique. These solar cells were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and energy dispersive X-ray (EDS) analysis. The crystallite size, inter-planer distance, and lattice constant values were calculated for the thin-film solar cells using XRD data. The current– voltage (I–V) characteristics of the solar cells were examined by solar simulator. © 2018, National Institute of Optoelectronics. All rights reserved

Investigation of Electrical Conductivity Properties and Electro Transport of a Novel Multi Walled Carbon Nanotube Electro Membrane under Constant Current

This study used multi-walled carbon nanotube in electro-membrane extraction studies under direct constant current for the first time for the electro transport of cypermethrin (CYP) from aqueous to acceptor phase. A novel and developed membrane exhibits visible and remarkable recovery values (82.76 %) for the removal of CYP under 0.3 A constant current at 60 V in 30 minutes. It is demonstrated that regenerating electro membrane by multi-walled carbon nanotubes (MWCNTs) increased the electrical conductivity, thermal Ea values of a novel membrane (750 meV) and stability, and it resulted in better and higher kinetic results on the transport process. This study presents a potential solution for the limited use of electro-membrane extraction at higher current values. Regenerating of the electro membrane by MWCNTs not only allows us to work even at high current values, it prevents the formation of electrolysis up to a certain current value in donor and acceptor phases. Thermogravimetric analysis of the novel membrane also confirms successful regeneration of the electro membrane by MWCNTs. Electro-membrane extraction studies have gained a new perspective and innovation by the use of MWCNTs in electro-membrane process. © 2020 Wiley-VCH Verlag GmbH & Co. KGaA, Weinhei

polyaniline/bentonite composite

In this study, the effects of irradiation on pure polyaniline and polyaniline/bentonite composites synthesized chemically were investigated by means of thermogravimetric measurements, UV, SEM, XRD, absorption and temperature dependent electrical conductivity in the temperature range of 85-400 K. The irradiation process was carried out in air in a conventional gamma chamber, which uses a Co-60 source and the samples were exposed to dose 40 kGy. The initial decomposition and first degradation temperatures of PAni/Bnt and Irradiated PAni/Bnt composites obtained from thermogravimetric measurements were higher than those of PAni and irradiated PAni. This could have been caused by the treatment with bentonite during aniline polymerization. The XRD patterns revealed that the peak positions of the as-prepared and irradiated samples were the same but the intensities of the peaks decreased with irradiation due to breaking of the polymer chain, which induces more amorphous regions in the polymer structure. It was found from temperature dependent conductivity measurements that the radiation significantly influenced the conductivity of PAni and PAni/Bnt composites. The conductivity results show that the dominant conduction mechanisms were hopping for all samples due to wide range of localized states present near the Fermi level. (C) 2012 Elsevier B.V.
