Previously we described the antinociceptive effect of magnesium sulfate and dizocilpine (MK-801) in the visceral and somatic rat models of pain. In the somatic model of pain, we established the influence of selective inhibitors of neuronal and inducible nitric oxide synthase on the antihyperalgesic effects of magnesium sulfate and dizocilpine. Therefore, the objective of the present study was t...

The potential use of synergistic mixtures of reagents for the solvent extraction of nickel (and cobalt) from lateritic leach liquors was pointed out in the early 1980s by Grinstead, who used dinonylnaphthalene sulphonic acid in conjunction with some 2-pyridyl compounds for the recovery of these metals from slightly acidic solutions1,2. Shortly thereafter, studies at Mintek revealed marked syner...

The burden of life on the earth is the source of biological contamination in water. Nanotechnology has promising contributions in control of microbial contaminations and medicinal plants further increase these properties. Presently, copper acetate and nickel oxide nanoparticles were synthesized using 1mM solution of each with Ziziphus mauritiana leaves extract as reducing agent. Nanoparticles w...

OBJECTIVE We examined the pulmonary toxicity of nickel oxide nanoparticle agglomerates in the rat lung following an intratracheal instillation. METHODS The weighted average surface primary diameter of nickel oxide nanoparticles was 8.41 nm, and the count median diameter of nickel oxide nanoparticle agglomerates suspended in saline was 1.34 µm. Male Wistar rats were exposed to 1 mg (3.3 mg/kg)...

methyl orange is one dye resulted from the textile industry. the aim of this study is to test theadsorption capacity of nickel oxide nanoparticles for removing the methyl orange from aqueoussolution. the parameters studied were the effect of temperature, contact time and initial ph ofsolution. results indicate that the removal efficiency of nickel oxide nanoparticles increases withincreasing co...

the combination of graphene and nickel oxide nanoparticles yields nanostructured electrochemical sensor formed a novel kind of structurally uniform and electrocatalytic activity material. in cyclic voltammetry studies, in the presence of epinephrine, nickel oxide / graphene  composite modified electrode shows a significantly higher current response for epinephrine oxidation. based on differenti...

A class of novel nickel cobalt oxide hollow nanosponges were synthesized through a sodium borohydride reduction strategy. Due to their porous and hollow nanostructures, and synergetic effects between their components, the optimized nickel cobalt oxide nanosponges exhibited excellent catalytic activity towards oxygen evolution reaction.

ncorporating Ni-laden waste sludge into kaolinite-based construction ceramic materials appears promising based on the identified nickel bearing hases, evaluated incorporation efficiency and nickel leachability of the products. Nickel aluminate spinel (NiAl2O4) results from sintering kaolinite nd nickel oxide between 990 and 1480 ◦C, with more than 90% incorporation efficiency achieved at 1250 ◦...

Mesoporous  MgO  microstructures  were  synthesized  using magnesium  acetate  tetrahydrate,  ammonium  oxalate  monohydrate and  Pluronic  F127  via  heating  at  40  °C  for  24  h  and  subsequent calcination. The mesoporous structure of magnesium oxide with the specific  surface  area  of  47m2 /g,  pore  volume  0.30  cm3 /g  and  the average pore size 24 nm is produced. According to ...
