Crystal Structure Analysis X-ray Diffraction Electron Diffraction Neutron Diffraction Essence of diffraction: Bragg Diffraction Reading: West 5 A/M 5-6 G/S 3 218. all POTCARs used in the run. More recently, NiO was used to make the NiCd rechargeable batteries found in many electronic devices until the development of the environmentally superior NiMH battery. If the "hubbards" key is missing, a GGA run is assumed. “Nickel and nickel compounds”. interface using the pymatgen.matproj.rest package will automatically have The conceptually simple structure is commonly known as the rock salt structure. [7][8], Long-term inhalation of NiO is damaging to the lungs, causing lesions and in some cases cancer. It is the precursor to many nickel salts, for use as specialty chemicals and catalysts. if you ran a Fe2O3 calculation with Materials Project parameters, In order to increase the economic value of local zircon concentrate from Bangka Island, NiO-YSZ was synthesized from Zirconia, ZrO2 that was prepared from local zircon concentrate. (1994). National Toxicology Program (NTP) (1996). Shin H(1), Choi SB, Yu CJ, Kim JY. [4] Black NiO is the precursor to nickel salts, which arise by treatment with mineral acids. & Oberg, S.G. (1981). At first build the crystal structure of NiO in Material Studio. Entry.parameters must contain a "hubbards" key which is a dict The structure is one-dimensional and consists of two NiO ribbons oriented in the (0, 0, 1) direction. Several million kilograms are produced annually of varying quality, mainly as an intermediate in the production of nickel alloys. NiO was also a component in the nickel-iron battery, also known as the Edison Battery, and is a component in fuel cells. For example, The coprecipitate of Al(OH)3Ti(OH)4 was obtained by adding aqueous ammonia slo [...]. this depends on calculations being run within the same input set. In a 2-year National Toxicology Program green NiO inhalation study, some evidence of carcinogenicity in F344/N rats but equivocal evidence in female B6C3F1 mice was observed; there was no evidence of carcinogenicity in male B6C3F1 mice. You can get help from the below link.. predictions of this material's bulk and shear moduli. Explore more synthesis descriptions Thus, strongly correlated materials have electronic structures that are neither simply free-electron-like nor completely ionic, but a mixture of both. of Health and Human Services, No. & Maples, K.R. Displaying lattice parameters for primitive cell; note that calculated cell volumes are typically overestimated on average by 3% (+/- 6%). Inhal Toxicol 6(2):167-183. Correct anion energies to obtain the right formation energies. Fate of inhaled nickel oxide and nickel subsulfie in F344/N rats. In general, band gaps computed with common exchange-correlation functionals such as the LDA and GGA are severely underestimated. these fields populated. Stability is tested against all potential chemical combinations that result in the material's composition. Characterization of crystalline structure and morphology of NiO thin films. Report of the International Committee on Nickel Carcinogenesis in Man.

It is the principal oxide of nickel. using Materials Project parameters, this would look like [10] NiO has a long retention half-time in the lungs; after administration to rodents, it persisted in the lungs for more than 3 months. The Ni atoms have a net magnetic moment and form an anti-ferromagnetic arrangement in the (111) direction of the fcc cell. The structure can be described by a rhombohedral unit cell with 4 atoms in the basis [CdG05]. The effect of pressure on the lattice parameters of NiO with a rhombohedral distorted B1 structure was investigated up to 141 GPa by in situ angle-dispersive x-ray diffraction using synchrotron radiation, an imaging plate, and a diamond anvil cell. The sintered oxide is used to produce nickel steel alloys. Like many other binary metal oxides, NiO is often non-stoichiometric, meaning that the Ni:O ratio deviates from 1:1. NiO crystallizes in the orthorhombic Cmmm space group. pymatgen.apps.borg package and obtained via the MaterialsProject REST NiO is Halite, Rock Salt structured and crystallizes in the cubic Fm-3m space group. About 4000 tons of chemical grade NiO are produced annually. E-mail: m.jansen@fkf.mpg.de Z. Naturforsch. NiO adopts the NaCl structure, with octahedral Ni2+ and O2− sites. Registered users can view Crystal structure of NiO under high pressure - NASA/ADS The effect of pressure on the lattice parameters of NiO with a rhombohedral distorted B1 structure was investigated up to 141 GPa by in situ angle-dispersive x-ray diffraction using synchrotron radiation, an … Physicochemical characteristics and biological effects of nickel oxides. Both Ni–O bond lengths are 1.72 Å. O2- is bonded in a … The crystal structures of NiO.3BaO, NiO.BaO, BaNiO 3 and intermediate phases with composition near Ba 2 Ni 2 O 5; with a note on NiO J. J. Lander Read article Similar articles Nickel(II) oxide is the chemical compound with the formula NiO. In some commercial processes, green nickel oxide is made by heating a mixture of nickel powder and water at 1000 °C, the rate for this reaction can be increased by the addition of NiO. Checks that POTCARs are valid within a pre-defined input set. Again, using the example of an Fe2O3 run section of our Calculations Guide. The energy of decomposition of this material into the set of most stable materials at this chemical composition, in eV/atom. However, strong Coulomb repulsion (a correlation effect) between d-electrons makes NiO instead a wide band gap Mott insulator. Entry.parameters must contain a "potcar_symbols" key that is a list of Carcinogenesis 8(2):305-313. 2016.
