A new and simple method for preparing confined copper nickel nanoparticles by thermal treatment of their respective cations inside Mobil Composition Matter 41 (MCM–41) hydrophobic nanopores is presented here. Surface modified MCM–41 materials were impregnated using high-pressure with II (Cu II) or (Ni aqueous solutions. After pressure release washing, the remaining metal cations, exclusively wi...

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...

Oxime extractants 3-tert-butyl-2-hydroxy-5-methyl benzaldehyde oxime (HL1) and 3-tert-butyl-2-hydroxy-5-methoxy benzaldehyde oxime (HL2) were synthesized and characterized by conventional spectroscopic methods. Suitable lipophilic nature of the prepared extractants allowed examining the ability of these molecules for extr...

Nickel (II), a ubiquitous environmental and industrial contaminant, is a well-known human carcinogen, particularly in human lung cancer. Although by itself it is a weak mutagen, nickel (II) is able to significantly enhance the genotoxicity of other mutagens and carcinogens, such as polycyclic aromatic hydrocarbons (PAHs) and ultraviolet light. Certain human populations, especially cigarette smo...

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...

CuInSe2 nanoparticles have been prepared by reacting cuprous chloride, indium chloride with alcohol and selenium powder. The nanoparticles were characterized by TEM, XRD, ICP-OES and SEM. The formation of CuInSe2 nanoparticles with different precursor ratios was investigated by in-situ high temperature X-ray diffraction analysis. It was found that the growth of CIS followed a vapor-liquid-solid...

Metal allergies can be a clinical problem, especially in atopic individuals. This study is unique and contributes with new knowledge in everyday life skin care of irritant and atopic dermatitis patients. The aim of the study was to determine the frequency of positive patch test reactions to metal contact allergens (potassium dichromate, cobalt chloride, nickel sulfate, white mercury precipitate...

oxime extractants 3-tert-butyl-2-hydroxy-5-methyl benzaldehyde oxime (hl1) and 3-tert-butyl-2-hydroxy-5-methoxy benzaldehyde oxime (hl2) were synthesized and characterized by conventional spectroscopic methods. suitable lipophilic nature of the prepared extractants allowed examining the ability of these molecules for extraction-separation of copper from its mixture with normally associated meta...

Single crystalline TiC nanowires have been synthesized through a chloride-assisted carbothermal reduction process using active carbon, TiO2 and NaCl powders as precursors and carbon-coated cobalt or nickel nanoparticles as a catalyst. The products were characterized by x-ray diffraction, electron microscopy, energy-dispersive x-ray spectroscopy and x-ray photoelectron spectroscopy. The TiC nano...

Nano oxides of Manganese Nickel and Cobalt Nickel were synthesized by chemical coprecipitation method from the reaction of respective metal sulfides of manganese, nickel, cobalt and sodium carbonate using ethylene diamene tetra acetic acid as an effective capping agent. The carbonate precursors were heated at different temperatures so as to form their oxides. Through the X-ray line broadening t...
