“…There has been few reports of using liquid medium, deionized water in PWD [132]. Coating of nanoparticles is usually done to hyberdize or passivate the nanoparticles [133]. Murai "et al" used the same approach by synthesizing the cupper nanoparticle by pulsed discharged method and successfully coating it with organic matter.…”

Metal Nanoparticles show specific physical and chemical properties attributed to its small size and high surface area to volume ratio. These chemical and physical properties using different strategies and conditions enhance its biological application especially in the field of medicine. Earth abundant and cheap cupper metal is the essential element in many processes and has been used as a focus element to synthesize nanoparticles by different methods using new technology, which are being broadly classified as biological methods that includes green synthesis, microorganism etc. and the non-biological synthesis which includes chemical and Physical methods. Thus, the imperative need to synthesize cupper nanomaterial that are economic and efficient is necessary. This review have briefly described the modern methods to synthesize nanoparticles particularly focusing on the non-biological methods of cupper nanoparticles. An overview of current methodologies that are used for cupper nanoparticle mainly chemical reduction using organic and inorganic solvents, Reverse micelle, microemulsion, polyol method and several physical methods such as vapor condensation, photo irradiation and plasma synthesis methods are discussed.

“…Since most alloy metals are brittle, reports on the pulsed wire discharge (PWD) of alloy wires for the fabrication of alloy nanopowders are limited. In order to synthesize alloy nanopowders, PWD has been performed using two types of wires [28,29]. For this reason, research has been focused on reducing the diameter of Sn-Bi or Sn and Bi wires for use in the PWD method.…”

Nanoscale Sn-Bi-Ag compound powders were successfully synthesized using the pulsed wire discharge (PWD) method. In PWD, when a high current is passed through high-density metal wires, the wires explode because of resistance heating, forming fine particles or metal vapor. In this study, we used Sn-Bi and Ag wires in order to obtain three-component nanopowders. A high current was applied to the wires between the electrodes in a N2 atmosphere. We discussed the results based on the K factor, which is the ratio of the charging energy of the capacitor to the vaporization energy of the wire. The three-component (Sn-Bi-Ag) nanoparticles were synthesized under a N2 atmosphere at 4 and 6 kV. From the particle-size distribution curves, it was found that the mean particle diameter (D1) values of the Sn-Bi and Ag nanopowders were within the range of 16.32-42.37 nm under each condition. The melting point of the Sn-Bi-Ag nanoparticles was found to be within the range of 188.68-214.97 ℃, which is about 40 ℃ lower than that obtained from the phase diagram and computational thermodynamics of the Sn-Bi-Ag system. In this study, the nanopowders were obtained by subjecting the wires at extreme energies, to improve their solid solubility. † (

“…The Al-Ni compounds have special place among all intermetallics. High strength, low density (5.68 g cm −3 ), high melting point (1638°C), high Young's modulus and good resistance to corrosion and oxidation are reasons of their reputation (ASM Handbook Committee 1992; Guo et al 2010;Prevot et al 2010;Dong et al 2011;Xu et al 2011;Ishihara et al 2012). Al-Ni intermetallics were used in the gas turbine engine blade in the airplane propulsion system, cover for thermal barriers and electronic composition in advance semi-conductor (Darolia 2000).…”

The reduction of nickel oxide and the formation of AlNi intermetalic phase at 1200°C for 2.5 till 10 min interval, during the aluminothermic method were studied, simultaneously. Aluminium was used as a reduction agent of nickel oxide in molten cryolite (Na 3 AlF 6 ). The changes in the amount of Ni in primitive metal samples were determined by atomic absorption analysis at different times. The achieved microstructure in quenched samples was observed by SEM. The prepared phases were recognised by XRD and EDS analysis. The results revealed that samples were combination of AlNi, Al 3 Ni 2 , Al 3 Ni and Al in the absence of Ni, NiO and Al 2 O 3 phases. The increasing of time causes the higher amount of AlNi phase to a continuous network.
