conclusions this easily fabricated electrode together with the fast and sensitive sw voltammetry was successfully applied for the determination of concentration of atz at trace levels, in different water samples. results the results revealed that decrease in peak current was proportional to atz concentration over the range of 5-75 ng/ml. the limit of detection (lod) and limit of quantification ...

Diesel vehicles have a huge role in the transportation of goods and people however they cause air pollutions. For this reason, researchers try to find alternative fuel additives decrease exhaust emissions. This experimental work focus on impacts oxygen content nanoparticle emissions 4 Stroke-6 cylinders turbocharged diesel engine fuelled with fuel. Nickel iron oxide nickel zinc nanoparticles do...

This article reviews the nanomaterials that have been prepared to date by pulsed sonoelectrochemistry. The majority of nanomaterials produced by this method are pure metals such as silver, palladium, platinum, zinc, nickel and gold, but more recently the syntheses have been extended to include the preparation of nanosized metallic alloys and metal oxide semiconductors. A major advantage of this...

Background and Aims: Nickel oxide nanoparticles (NiO-NPs) are one of the most used nanoparticles, especially as photosensitizers. Although some studies evaluate their toxicity in liver, information about at cellular molecular levels is still controversial. In present study, it was aimed to investigate vitro toxic potentials NiO-NPs (average size 15.0 nm) liver (HepG2) cell line. Methods: were ...

In this research, the nickel oxide was dissolved in cryolite at temperatures of 880, 940 and 1000°C. In order to reduce the nickel oxide, aluminum was added to the salt. Simultaneously the nickel oxide was reduced and Al3Ni2 intermetallic compound was formed. In the duration intervals of 2.5-40 minutes samples of the salt and metallic phases were taken. The variation of the nickel content in me...

Manganese-nickel (Mn-Ni) oxide films were electrodeposited on a graphite sheet in a bath consisting of manganese acetate and nickel chloride, and the structural, morphological, and electrochemical properties of these films were investigated. The electrodeposited Mn-Ni oxide films had porous structures covered with nanofibers. The X-ray diffractometer pattern revealed the presence of separate ma...
