“…Produce of Multi-Wall Nanotubes can be achieved without utilize of catalyst precursors when Single walled Carbon Nanotubes will be prepared by utilizing of various types of precursors` catalyst as well as the metal anode which composed from graphite and a transition metal. There different types of transition metals like metals Cobalt, Iron, Nickle from the first row of transition metal, Silver, Platinum, palladium From the second row of transition [73][74][75][76][77][78][79][80][81][82][83][84] It can also, used mixture of metals with grapheme to prepare anode like Cobalt with Radium and with platinum, Nickle with yttrium which give yield of 90% from Single-walled of Carbon Nanotubes [85].…”

The carbon nanotube (CNT) represents one of the most unrivaled contrivances in the domain of new technology represented by contemporary revolution of nanotechnology. CNTs is closed to be the more important branch of nanotechnology which have been matured painstakingly meanwhile the last 20years by many investigators and different types of application papers, researches and studies around the expert because of their senior potency in various area. These tubes are rolled in the hybridization found in the grapheme type of carbon nanotubes. The paramount portions of CNTs are their nimble weightiness, small size with a high aspect ratio, pretty stretchy strength, and kindly forthright traits, which make them profitable as tautologies for various materials such polymers, metallic flatness's and earthenware. CNTs also have potential enforcements in the range of nanotechnology, medical Nano manufacture, transistors, actuators, sensors industrialization, and membranes preparation and capacitors industry. There are assorted techniques, which can be utilized for the compilation of CNTs. These implicate the arc discharge mode, chemical fumigate precipitation (CVD),the laser ablation way and the sol- gel method. CNTs can be monowalled, duplicate-walled and multi-walled. CNTs have individual mechanistic, electrified and optic qualities, commonalty of which has been extensively elaborated. The sitting article-review is converging on the composition, functionalization, differences and enforcements of CNTs. The toxic influence of CNTs is also offered in a concise form. It is clear, by the beginning of the last century, that carbon Nano-tubes (CNTs) were important in the fields of health, such as medicine and pharmacy, which had entered into system of drug delivery. The ability of these compounds attracted the interest of researchers in the fields of biomedicine and its biomedical applications such as advanced imaging, regeneration of organism tissues, drug disposal or gene delivery. There is a lot of interesting evidence about the unique advantages of nanotubes that confirm their effectiveness compared to their negative effects. © 2018 JASET, International Scholars and Researchers Association

“…Therefore, resolving the problem of flying dust in the preparation environment is crucial [17]. The use of Electrical Discharge Machining (EDM) to obtain nanomaterials from melting the surface of electrode materials is called the Electric Spark Discharge Method (ESDM) [18][19][20]. A recent study employed an ESDM for the preparation of WO 3 • H 2 O nanoparticles [21].…”

This study enhanced the discharge energy of an existing micro-electric discharge machining (EDM) system to provide the system with the ability to prepare nano-tungsten (nano-W) colloid. The energy- enhanced EDM system, referred to as the upgraded-micro-EDM system, enables spark discharge using tungsten wires immersed in deionized water to produce nano-W colloids. Compared with the chemical preparation method, the processing environment for preparing colloids will not have nanoparticle escape in this study. Among the nano-W colloids prepared using the upgraded-micro-EDM system and an industrial EDM system, the colloid prepared by the upgraded-micro-EDM system exhibited more favorable absorbance, suspensibility, and particle size. The colloid prepared by the upgraded-micro-EDM system with the pulse on time and off time of 10–10 µs had an absorbance of 0.277 at the wavelength of 315 nm, ζ potential of −64.9 mV, and an average particle size of 164.9 nm. Transmission electron microscope imaging revealed the minimum particle size of approximately 11 nm, and the X-ray diffractometer spectrum verified that the colloid contained only \({\text{W}}_{2.00}\) and W nanoparticles. Relative to industrial EDM applications for nano-W colloid preparation, the upgraded system boasts lower costs and smaller size, and produces nano-W colloid with superior performance. These advantages contribute to the competitiveness of electrical spark discharge method in the preparation of high-quality nano-W colloids.

“…A number of chemicals can be used as protecting agents in the synthesis of AgNPs. However, the most commonly applied stabilizers and protective agents in nanoparticles synthesis are polymers: gelatin [14], D-sorbitol, polyvinyl pyrrolidone (PVP) [15] and PMVE (poly(methylvinylether)) [16]. Among all polymer stabilizers of silver nanoparticles, poly(N-vinylpyrrolidone) is considered an excellent dispersant as it exhibits favourable protecting properties owing to its unique structure [17,18].…”

1 The contact non-equilibrium low-temperature plasma technique is used to synthesize silver nanoparticles (AgNPs) employing polyvinyl pyrrolidone (PVP) as a capping agent. Influences of PVP concentration on the formation efficiency of silver nanoparticle, their average size and stability have been studied. The synthesized silver nanoparticles had a significant antibacterial activity against two strains of Gram bacteria. Silver nanoparticles (AgNPs)-alginate composite beads with different PVP concentration were synthesized as materials for water purification.Анотація.
