Abstract:
AbstractA nickel-rich conductive anti-corrosive coating (CACC) was fabricated to improve the corrosion resistance of the carbon steel grounding materials. The coating was tested using surface contact resistance measurement, electrochemical impedance spectroscopy (EIS) and surface characterization. The results indicate that the increase of the nickel powder content in the coating induces its electrical conductivity enhancement; the surface contact resistance is as low as 0.05 Ω/cm2 when the nickel powder content is 20%. The EIS data show that the anti-corrosive performance of the coating with 2

Abstract:
The content of nickel was investigated in the liver of sixty-nine pigs from ten different genetic lines, produced in Vojvodina. Nickel was determined by the flame atomic absorption spectrometry after mineralization by dry ashing. The difference in the nickel content among different genetic lines of pigs was not significant (P > 0.05) in the analyzed liver tissues. Nickel levels ranged from 13.02 to 68.21 ?g/100g with a general average of 26.73 ?g/100g. Average nickel content, found in this study, is in agreement with the contents observed in pig liver in other countries.

ABSTRACT Most crude oils in contact with water form water-in-oil emulsions. The stability of these emulsions will vary. When spilled crude oil emulsifies, it becomes viscous and expands in volume, becoming more difficult to recover, chemically disperse, or ignite. The ability to better predict the emulsion-forming behavior of a specific crude oil would greatly aid oil spill response decisions. The problem is complex because of the various stabilizing mechanisms. This study identified surface active agents, that is, porphyrins, as key compounds that contribute to the emulsification of crude oil

Abstract The paper presents the changes in chromium and nickel content in goat’s rue biomass cultivated in the years 2005-2007. Field test was carried out on the experimental field belonging to the University of Natural Sciences and Humanities in Siedlce. The tests included six objects with constant phosphorus fertilisation and differentiated potassium fertilisation. During each year of the tests, three cuts of the test plant in budding stage were harvested. Total Cr and Ni content in the plant and soil was determined using inductively coupled plasma-atomic emission spectrometer. The uptake of

Abstract:
Information was obtained on the content of cobalt and nickel in soil, litter, and organs of Scots pine in the conditions of the Yelets industrial center. It was found that, under pollution conditions, the content of cobalt and nickel in vegetative organs, soil, litter is higher than the control values. Moreover, their content increases both during the growing season and with an increase in the age of the pine (needles and shoots). There is an uneven accumulation of metal in various organs of Scots pine. A high level of correlation was noted: between the content of cobalt in the soil and needle

Abstract:
Nickel is the most common cause of contact allergy in the general population and the most frequently detected allergen in patients patch tested for suspected allergic contact dermatitis (ACD). ACD from nickel is a typical type IV hypersensitivity. Nickel allergy is mostly caused by nonoccupational exposure, such as jewelry and clothing decorations, metal tools, medical devices (mainly orthopedic and orthodontic implants, cardiovascular prosthesis), eyeglasses, utensils, keys, pigment for paint, cosmetics, and food (mainly legumes, chocolate, salmon, peanuts). Occupational exposure can involve

Data in literature seem to show that, in patients with contact allergic dermatitis, dietary nickel might be a cause of systemic dermatitis, but little information exists in literature about the role of nickel sensitization and dietary nickel in patients with allergic-like chronic dermatitis syndromes. The prevalence of nickel sensitization in patients with chronic allergic-like, non-IgE-mediated skin diseases, and the possible impact of dietary nickel on symptom provocation and persistence has been assessed in the present retrospective study on a case series of 1726 patients referred to our al

Abstract:
The depletion of sulfide nickel ore and the growing of stainless steel demand each year cause the use of low-grade laterite nickel ore continues to increase. Due to very low nickel content, there is no optimal process to extract them. One of the alternative processes being developed now is the sintering-blast furnace process which produces Nickel Pig Iron (NPI). This research was conducted by sintering limonitic laterite nickel ore using charcoal as fuel and limestone as a flux. This research aims to analyze the effect of charcoal mass variation on Ni content, sinter strength, and the yield on

A hundred soil samples were analysed in all, originating from four subtypes of calcareous black soil (organogenic, organo-mineral, brownized and loessivized black soils). The extraction of mobile Ni was carried out with 1.0 N HCl and its content was determined by atomic absorption spectrophotometry. The obtained results indicate that mobile Ni content in the investigated soils varies within a wide range, from 5.0 to 251.3 mg/kg that it

Nickel industry is one of the most strategic industries because its widely used. Nickel slag as a by-product of nickel processing presents the potential for improving process efficiency. In this study aim to determine the effect of the addition of sodium sulfate additives and also the temperature in the reduction process of nickel slag. The research was preceded by preparation of nickel slag samples with crushing and sieving up to 200 mesh. The nickel slag is then reduced at 800°C, 900°C and 1000°C temperature without adding sodium sulfate and by adding sodium sulfate with 1 hour holding time.

Abstract:
To recover iron from water-quenched nickel slags, CaO was added. Thermodynamic analysis showed that CaO promotes the reaction between fayalite (Fe2SiO4) and O2. Phase diagrams of the FeO-SiO2-MgO-CaO slag with various CaO contents in an air atmosphere drawn by FactSage 7.1 showed that the phase components can be significantly affected by the CaO contents. With increasing CaO content, the fusion characteristic temperatures decreased rapidly to a minimum and subsequently increased slightly. The oxidization of Fe2SiO4 in nickel slags was accelerated significantly by the addition of CaO, which led
