Abstract:

The hydrated nitrates of chromium(III), cobalt(II), nickel(II) and copper(II) dissolved in molten calcium nitrate tetrahydrate at 43°C to form clear coloured solutions. Their spectra, between 30000 and 11000 cm-1, showed maxima closely similar in wavenumber to those of the corresponding aqueous solutions, and indicated similar octahedral coordination by oxygen from the ligands. However, slightly higher molar absorption coefficients of the metal cations in the molten solutions than those of the aqueous solutions suggested the possibility of mixed coordination by both aqua and nitrato groups. Nickel(II) complexes were rapidly solvolysed in the melt but cobalt(III) displayed more varied behaviour, intriguingly different from those of their aqueous solutions.

Abstract:

Abstract Nickel nitrate, nickel Perchlorate and cobalt nitrate can form homogeneous liquid phases with aniline and water. The shapes of the single phase regions in the ternary phase diagrams were determined. Five types of crystals were obtained in the system nickel nitrate/aniline/water. The structures of Ni(NO3)2 · 6C6H7N · 2H2O, Ni(NO3)2 ·4C6H7N · 2H2O , and Ni(NO3)2 ·2C6H7N · 4H2O have been determined by single crystal X-ray diffraction. All structures show chains of nickel ions and nitrate ions connected by water or aniline molecules. They can be interpreted as one dimensional ion pairs.

Abstract:

Electrochemical studies on nickel hydroxide have shown that three reduction reactions take place simultaneously at the cathode to reduce nitrate to nitrite, nitrite to ammonium ion and nitrate to ammonium ion. All the three reactions produce hydroxyl ion which raise pH to a level favorable to precipitate Ni(OH)2. Current density, which regulates flow of OH- supply, has prominent effect on the process and products. It determines whether α- or β-Ni(OH)2 would be precipitated and has a direct relationship with size and structure of the product and also with the associated water molecules. Replacement of Ti anode with consumable Ni sheet remarkably improves current efficiency (production rate) and decreases power consumption.

Abstract:

The orientation and electrical properties of Pb(Zr,Ti)O3 thin films deposited on a Pt/Ti/SiO2/Si substrate using lanthanum nickel nitrate as a conductive buffer layer were analyzed. The lanthanum nickel nitrate buffer layer was not only electrically conductive but also effective in controlling the texture of the lead zirconate titanate (PZT) thin film. The role of the lanthanum nickel nitrate buffer layer and its effects on the orientation of the PZT thin film were analyzed by x-ray diffraction, electron beam back-scattered diffraction, and scanning electron microscopy. The annealed lanthanum nickel nitrate buffer layer was sufficiently conducting for use in longitudinal electrode configuration devices. The dielectric, ferroelectric, and piezoelectric properties of the highly (100) oriented PZT films grown with the lanthanum nickel nitrate buffer layer were measured and compared with those of (111) and (100) oriented PZT films deposited without a buffer layer.

Abstract:

In this work, nickel-zinc ferrite nanocrystalline powder has been prepared by a sol-gel autocombustion technique using nitrate-citrate gel obtained from metal nitrates and citric acid solution. Characterization of the nitrate-citrate gel, as-burnt powder and calcined powder at different calcination conditions were investigated by using XRD, FTIR and SEM techniques. The results revealed that the nitrate-citrate gel exhibits a self-propagating behavior after ignition and showed that the different calcination conditions affect the crystallite size of the synthesized powder as well as its phase constitution.

Abstract:

Abstract Recent theoretical and experimental results, based on an extension of the Einstein theory of relativity, show that nuclear reactions of a new type can occur. In this framework, the feasibility of the deactivation of radionuclides is investigated. This paper reports the deactivation of nickel nitrate made of radioactive Nickel-63 in nitric acid by using ultrasounds. From the applicative point of view, it is a more realistic system then the previously considered thorium, not only because the molecule and the system are more complex but also because the problems related to the high corrosion and radioactivity have been treated at the same time, thus miming realistic situations like those of deactivation of nuclear waste.

Abstract:

Corn cob, an agricultural waste, is paralyzed at different temperatures (700oC, 800oC and 900oC). Microwave absorption of carbon in the frequency range of 2 GHz to 8 GHz is reported. Carbon activated Â with 5%Â nickel nitrate showed more than 90% absorption of microwave in the frequency range from 6 GHz to 8 GHz, while carbon activated Â with 10% Nickel nitrate treated corn cob showed 90% absorptionÂ in the frequency range of 2.5 GHz to 5 GHz. Carbon showing the best absorption are characterized by XRD, Raman spectra and SEM . It is suggested that corn cob treatmentÂ Â alone with KOH did not improve the microwave absorption, whereas treatment along with nickel nitrate improved the absorption property much better. It is proposed that treatment with nickel nitrate helps in creating suitable pores in carbonÂ Â which improved the absorption behavior because while treating carbon with 1N HCl helps to leach out nickel creating equivalent amount of pores in the carbon.

Abstract:

Electromagnetic Interference (EMI) issue is gaining more attention as the result of proliferation of electrical and electronic devices. In order to reduce the exposure to EMI, shielding and absorbing materials are often applied. This paper discussed the process of forming the nickel-zinc ferrite as one of the absorbing material by mixing the nickel nitrate, zinc nitrate and iron (III) nitrate together. X-ray diffraction, scanning electron microscopy, and dielectric measurement are carried out to reveal the characteristic of the specimen. The sintering temperature determines the formation of a pure spinal nickel-zinc ferrite and grain size.

Abstract:

Both the beneficial and the adverse effects of various nickel level supplements on growth and chlorophyll content of canola plants were evaluated while either urea or ammonium nitrate was supplied as the sole N source in the nutrient solutions. This study was arranged in completely randomized with three replications. Treatments included nutrient solution cultures containing urea and ammonium nitrate at the rate of 84 mg N L-1 separately as nitrogen sources with four nickel levels as NiSO4.6H2O at the rates of 0, 0.01, 0.05 and 0.1 mg Ni L-1. Plants were allowed to grow for 6 weeks then leaves chlorophyll content and shoots and roots fresh and dry weight were determined. Both plant growth and leaves chlorophyll content of the urea-fed plants increased significantly with the increase in nickel content up to 0.1 mg Ni L-1. However, root fresh and dry weight increased up to 0.01 mg Ni L-1 and started to decrease with further increase in solutions nickel content. Nickel did not affect these parameters with plants supplied with ammonium nitrate significantly. In these plants, the optimum nickel level for shoot growth and leaves chlorophyll content was 0.05 mg L-1 and for root fresh and dry weight was 0.01 mg Ni L-1. Further increase in Ni concentration reduced growth. As a whole, plants received urea plus nickel performed better than those received ammonium nitrate plus nickel.

Abstract:

The production of hydrogen by steam reforming of ethanol was carried out on SBA-15-supported nano NiO catalyst synthesized by the equivalent-volume impregnation method with two different Ni sources (nickel nitrate and nickel sulfamate). The catalyst was characterized by N2 adsorption–desorption, X-ray diffraction, X-ray photoelectron spectroscopy, and transmission electron microscopy to examine the physical and chemical properties. The activity tests were performed with the steam, with water/ethanol molar ratio ranging from 2:1 to 15:1, the N2 flow rate from 20 to 120 mL min−1 to determine the space-time, and the temperature range from 623 to 923 K on the two different Ni source catalysts. A favorable operating condition was established at 823 K using water/ethanol = 6 molar ratio and carrier gas (N2) flow of more than 50 mL min−1 for nickel nitrate source, but for nickel sulfamate source, the optimum temperature changed to 773 K and other conditions were the same as for the nickel nitrate source. After eliminating the influence of internal and external diffusion factors, an empirical power-law kinetic rate equation was derived from the experimental data. The non-linear regression method was used to estimate the kinetic parameter. The activation energy of the catalyst was then calculated, and the supported nickel nitrate and nickel sulfamate catalysts were 25.345 and 41.449 kJ mol−1, respectively, which was in agreement with the experimental and model-predicted results.

AbstractThe novel potassium nickel borate nitrate K7Ni[B18O24(OH)9](NO3)6 ·(H3BO3) was obtained from a simple hydrothermal synthesis in a stainless-steel autoclave at T = 513 K starting with nickel dichloride hexahydrate, and boric and nitric acid with the pH adjusted to 8 by KOH. Single-crystal X-ray diffraction data provided the basis for the structure analysis and refinement. The compound crystallizes in the trigonal space group R3̅ (no. 148) with the lattice parameters a = 1222.29(8) and c = 5478.4(4) pm. Generally, K7Ni[B18O24(OH)9](NO3)6 ·(H3BO3) is comprised of nitrate layers and complex nickel borate layers surrounded by boric acid, nitrate anions, and potassium cations.

Abstract:

The aim of this investigation was to assess the treatment efficiencies for gully pot liquor of 12 experimental vertical-flow constructed wetland filters containing Phragmites australis (Cav.) Trin. ex Steud. (Common Reed) and filter media of different adsorption capacities in a cold climate. Seven of the twelve filters received inflow water spiked with heavy metals. For one year, hydrated copper nitrate and hydrated nickel nitrate were added to sieved gully pot liquor to simulate contaminated primary treated storm water runoff. The inflow concentrations for dissolved copper, nickel and nitrate-nitrogen were approximately 1.0, 1.0 and 1.45 mg/l, respectively, which represent mean loading rates of 0.063 g/m2/d for Filters 2 and 7 to 11, and 0.115 g/m2/d for Filter 12. For these filters receiving metals, an obvious breakthrough of dissolved nickel was recorded after road gritting and salting during winter. Sodium chloride was responsible for nickel leaching. Reductions of copper, nickel, biochemical oxygen demand and suspended solids were frequently insufficient compared to international secondary wastewater treatment standards. Moreover, the overall filtration performance for all filters was similar.

Abstract:

The equilibrium adsorption of nickel on γ-alumina was studied at 293 and 333 K. Nickel nitrate solutions in the range 0.1 - 2% (w/v, expressed as NiO) were used. Both the equilibrium constant and the number of adsorption sites increased with the adsorption temperature. Adsorption and desorption rate constants were estimated by fitting a theoretical model to the profiles obtained by impregnation of γ-alumina thin layers with nickel nitrate solutions. Representative solid samples differing in nickel contents were studied along both isotherms by X-ray diffraction, diffuse reflectance and X-ray photoelectron spectroscopy. It is concluded that, in the composition range studied, nickel forms a partially inverted spinel (NiAl2O4); the degree of inversion being greater in the samples prepared at 293 K than in those corresponding to 333 K. Also, the dispersion of nickel species is constant for each adsorption temperature.

Abstract:

The adrenal gland of the rat shows gradual changes during its growth and differentiation. During the first days of life there is a decrease of adrenal weight and cortical volume. During this period the cell-to-cell attachments of the cortical tissue and the permeability of the intercellular spaces to the markers during that period has not received special attention. The purpose of this work is to describe in the neonatal cortex: 1) The permeability of the intercellular spaces to the nickel nitrate used as marker, and 2) Some structural observations of the zone of cellular adhesion between cortical cells. The marker fills the lumen of microcanaliculi. With this purpose the following procedure are made: Adrenal gland of twenty Wistar rats of 1,4,10 and 90 days of age are used. In the day of sacrifice both glands are dissected after perfusion with nickel-glutaraldehyde via cannulation of cardiac left ventricle. The nickel-glutaraldehyde is prepared by dissolving 1 g of nickel nitrate in 0.1M cacodylate buffer pH 7.2. After perfusion, fragments of the glands are refixed in 1% osmium K-ferrocyanide and processed by TEM.

Abstract:

AbstractSmall amount of different nickel precursors (nickel nitrate or nickel molybdate) were incorporated into MoBi-based catalyst to produce a series of modified composite oxides catalysts for the selective oxidation of isobutene (IB) to methacrolein (MAL). Nickel nitrate introduction can effectively improve IB conversion and nickel molybdate introduction can remarkably enhance the selectivity of MAL. The XRD results show that nickel introduction has some influence on the catalyst structure. The catalyst modified with NiMoO4 showed the highest MAL yield of 87.8%. According to the H2-TPR, BET and XPS results, the catalyst modified with NiMoO4 exhibits lower reduction temperature, higher pore volume and better lattice oxygen mobility, which were confirmed to be responsible for excellent catalytic performance for the title reaction. In the case of an excess of O2, an empirical kinetic model was used to evaluate the rate data. The activation energy (Ea) was found to be 172.4 kJ mol−1.

Full text

Abstract:

Chlorides and nitrates of zinc(II), nickel(II) and cobalt(II) react with 2-phenyl-2-imidazoline to give complexes of the type [ML2X2]?nH2O (M=Zn, Ni or Co; L=2-phenyl-2-imidazoline; X=Cl or NO3; n=0, 1 or 2). The complexes were synthesized and characterized by elemental analysis of the metal molar conductivity, magnetic susceptibility measurements and IR spectra. The molar conductances of the zinc(II) complexes in DMF solutions indicate that the complexes behave as non-electrolytes. The values of magnetic conductivity in the case of nickel(II) complexes indicate that one of the coordinated anions (chloride or nitrate) has been replaced by DMF molecule. The molar conductivity values of cobalt(II) complexes indicate the partial substitution of coordinated anions with solvent molecules. The room temperature effective magnetic moments and IR data of the complexes suggest that all Zn(II), Ni(II) and Co(II) complexes have a tetrahedral configuration, which is realized by participation of the pyridine nitrogen of two organic ligand molecules, and two chloride or nitrate anions typical for these classes of organic ligands.

Abstract:

Abstract Nickel aluminate oxide (NiAl2O4) was prepared using chitosan as polymeric precursor and ammonia solution as a precipitating agent. In addition, nickel nitrate and aluminum nitrate salts were used as sources of Ni and Al, under stoichiometric amounts (molar ratio Ni:Al = 1:2). NiAl2O4 particles were prepared at different calcination temperatures and their properties were investigated. The synthesized materials were characterized by X-ray diffraction, infrared spectroscopy, atomic force microscopy, thermogravimetric analysis and nitrogen adsorption-desorption isotherms. The results showed that the thermal treatment process strongly influence on the formation of a single-phase structure of NiAl2O4 spinel. Nickel aluminate spinel with a porous structure and high surface area was obtained at temperatures above 700 ºC.

Abstract:

<p>Model trans-esterification reaction of n-butylbenzoate with phenyl-p-chlorobenzoate in the molar ratio of 20:1 has been studied. In order to evaluate catalysts based on lanthanide system the activity of nyodymium compounds – neodymium acetate, neodymium acetylacetonate and nitrate complex with benzo-12-crown-4 (neodymium nitrate coronate) – has been studied in the model trans-esterification reaction of n-butylbenzoate with phenyl-pchlorobenzoate. The effect of the electronic structure of the metal on the catalytic activity of the coronates of lanthanum, cerium, praseodymium, neodymium, samarium, terbium and erbium nitrates has been studied. In order to estimate the optimum concentration of the catalysts, a study of the dependence of the transesterification reaction on concentration of neodymium nitrate coronate was carried out. An asymptotic nature of the concentration dependence on the catalytic activity of lanthanide compounds has been observed. In order to look for new classes of inhibitors of trans-esterefication reaction, the model trans-esterificatiom reaction of n-butylbenzoate with phenyl-p-chlorbenzoate has been studied in the presence of some carborane derivatives: cesium salts of bis-1,2-(dicarbollyl) complexes of iron, cobalt and nickel(3+) and bis-1,2(dicarbollyl) nickel(4+) [(C<sub>2</sub>B<sub>9</sub>H<sub>11</sub>)2Me]. Some of these compounds were found to be effective inhibitors. The dependence of the constant rate of the model trans-esterification reaction of n-butylbenzoate with phenyl-p-chlorobenzoate on the concentration of cerium salt of bis-1,2-(dicarbollyl) complex of nickel has been studied to determine the optimum concentration of inhibitors. The influence of the ester chemical structure on the activity of ester groups in the trans-esterification activity has been determined in the reaction of di-n-butylterephthalate with different p-substituted derivatives of phenylbenzoate (phenyl-p-methoxybenzoate, phenyl-p-methylbenzoate, phenylbenzoate, phenyl-pchlorobenzoate, phenyl-p-nitrobenzoate, p-methoxyphenylbenzoate, p-methylphenylbenzoate, p-chlorophenylbenzoate, p-nitrophenylbenzoate, n-butylbenzoate, di-n-butylterephthalate) in presence of the samarium nitrate coronate.</p>

Abstract:

Nickel coated gadolinium doped ceria (GDC) powder was synthesized by microwave radiation and combustion. For the synthesis, the precipitates of gadolinium cerium oxycarbonate hydrate (GdxCe2-xO(CO3)2·H2O) were formed by a microwave radiated reaction between cerium nitrate (Ce(NO3)3.6H2O) and gadolinium nitrate (Gd(NO3)3.6H2O) and urea (CO(NH2)2), then nickel coatings on the gadolinium cerium oxycarbonate hydrate were performed by further microwave reaction between nickel chloride and urea. The shape and size of the gadolinium cerium oxycarbonate hydrate particles were critically dependent on aging time during microwave radiation. The irregular particles were transformed to rod shape particles with well-crystallized with increasing aging time to 40 min at 70 - 80°C because of the gradual decomposition of urea during microwave radiation. Small nickel precursor particles were homogeneously coated on the gadolinium cerium oxycarbonate hydrate particles with rod shape with aid of microwave radiation at 80 °C for 40 min. As a result, the nickel coated GDC nanopowders were sucessfully produced by the microwave radiation synthesis and further microwave combusted at 450°C for 20 min.

Abstract:

Nickel oxide (NiO) was prepared by the hydrothermal method using hydrogen peroxide to form a nickel peroxide complex, and irregular spherical and rod-shaped NiO nanoparticles were obtained. The factors that influence the physical properties of NiO nanoparticles were studied using scanning electron microscopy (SEM), isothermal gas adsorption/desorption by Brunauer, Emmett and Teller (BET), and X-ray diffraction (XRD) techniques. This study found that the precursor salt chosen (nickel acetate or nickel nitrate) significantly affected the shape, particle size, and surface area of the synthesized nanosized NiO powders. The ratio of hydrogen peroxide (H2O2) to nickel nitrate or acetate and the heating rate of calcinations were also important in determining the physical properties of the nanosized NiO. The unmodified PAni electrode shows no activity for the methanol oxidation reaction in 0.1 M NaOH. However, the nickel-modified PAni electrode is a good catalyst for this reaction and high current densities can be reached. The height of the oxidation peak of methanol increases by increasing the alcohol concentration. The results indicate that the reaction of the electro-oxidation of methanol is an activation-controlled proceeding by a direct chemical reaction with NiO(OH) for thin nickel oxides and by charge transfer with the electrode for thick oxides.

Abstract:

NiO is a candidate material for a variety of potential applications, for example, active optical filters, antiferromagnetic layers, coloring agents for enamel, pigments, catalysts, cathode materials for alkaline batteries and temperature sensors. Nanocrystalline nickel oxide powders have been synthesized by the combustion technique using glycine as a fuel and nitrate as an oxidizer. The precursor solution was heated to evaporate water, yielding a viscous liquid. It ignited and underwent self-sustaining combustion, producing an ash composed of the oxide product. The as-synthesized particles have been characterized by Xray diffraction (XRD), and scanning electron microscopy (SEM). Nanocrystalline nickel oxide was possible to be obtained from fuel-lean ratios. The smallest crystallite size was obtained under fuel-lean (0.09) formulation. The size of the NiO nanoparticles varied from 4 to 18 nm.
