In the title solvated complex, [Ni(C(17)H(21)N(3)O)(NCS)(2)(CH(3)OH)]·CH(3)OH, the Ni(2+) ion is coordinated by one phenolate O, one imine N, and one amine N atom of the tridentate Schiff base ligand, two thio-cyanate N atoms and one methanol O atom, resulting in a distorted cis-NiO(2)N(4) octa-hedral geometry. The chelate ring formed by the phenolate O and imine N atoms approximates to an enve...
The discovery of superconductivity in Nd${}_{1\ensuremath{-}x}$Sr${}_{x}$NiO${}_{2}$ has resulted a flurry experimental and theoretical work to understand the nature nickelate as compared that cuprates pnictides. Here, authors use combination LDA+U linear-response methods study magnetic exchange interactions Nd${}_{1\ensuremath{-}x}$Sr${}_{x}$NiO${}_{2}$. analysis reveals an underlying Mott ins...
In the title complex, {[Ni(2)(C(14)H(4)N(2)O(8))(H(2)O)(6)]·2H(2)O}(n), the two Ni(II) atoms are located in different special positions (one on a twofold rotation axis and the second on a centre of symmetry) and have different distorted octa-hedral environments (one by two N atoms from a bipyridine unit, two O atoms from two water mol-ecules and two O atoms from two carboxyl-ate groups, and the...
Thin oxide films formed on commercial metal/porcelain Ni-Cr alloy containing Be, were studied by using the electron probe microanalyzer (EPMA) with the glass lining technique and by the X-ray diffraction method with the Debye-Scherrer camera. Oxidation was restricted to form thin oxide films as follows; at 700•Ž for 5 minutes in air, at 1,000•Ž for 2 minutes in air, and at 1,000•Ž for 40 minute...
In this data, the properties of transparent TiO2 film for Schottky photodetector are presented for the research article, entitled as "High-performing transparent photodetectors based on Schottky contacts" (Patel et al., 2017) [1]. The transparent photoelectric device was demonstrated by using various Schottky metals, such as Cu, Mo and Ni. This article mainly shows the optical transmittance of ...
Nickel cobalt oxides with various Ni/Co ratios were synthesized using a facile template-free approach for electrochemical supercapacitors. The texture and morphology of the nanocomposites were characterized by powder X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and Brunauer-Emmett-Teller analysis (BET). The results show that a hierarchical ...
In the polymeric title complex, {[Ni(C(2)H(5)NO(2))(2)(H(2)O)(2)]Cl(2)}(n), the Ni(II) atom lies on an inversion center and is in a distorted octa-hedral NiO(6) configuration, with four carboxyl-ate O atoms from four zwitterionic glycine mol-ecules forming the equatorial plane and two water O atoms occupying the axial positions. The Cl(-) counterions lie in the inter-stices. The Ni(II) complexe...
A cermet (ceramic metal composite) of Nickel and Yttria stabilized Zirconia (YSZ) is the most commonly used fuel electrode for Solid Oxide Fuel Cells (SOFC). The properties of such cermets depend strongly on their microstructure. Several Ni/YSZ cermet samples with different Ni content and Ni and 8YSZ grain size have been prepared. The thermal expansion coefficient (TEC) of these samples was mea...
In this work, we report on the importance of layer distribution after annealing to form a high quality ohmic contact p-type GaN, using nickel (Ni) and gold (Au) thin association. Both standard GaN/Ni/Au its reverse, GaN/Au/Ni GaN were studied. The Au/Ni stack exhibits most promising results in study. While quasi-linear current-voltage (I-V) characteristic, counterpart, GaN/Au/Ni, shows pure beh...
Reduction of an oxide in hydrogen is a method frequently employed in the preparation of active catalysts and electronic devices. Synchrotron-based time-resolved X-ray diffraction (XRD), X-ray absorption fine structure (NEXAFS/EXAFS), photoemission, and first-principles density-functional (DF) slab calculations were used to study the reaction of H(2) with nickel oxide. In experiments with a NiO(...
