Nanoparticles with their specific properties newly have drawn a great deal of attention of researchers [1-3]Yttrium iron Garnet magnetic nanoparticles (YIG-NPs) are promising materials with novel applications in microwave, spintronics, magnonics, and magneto-optical devices.However, achieving stable and remarkable magnetic YIG-NPs has been remaining as a great challenge. In this paper, synthesized YIG-NPs by modifying co-precipitation (MCP) method is reported. Structural and magnetic properties of final products are compared to those of the materials prepared by citrate-nitrate (CN) method. Smaller crystals and particle size have been found by MCP method comparing to that of synthesized by CN method. Using a relatively low annealing temperatures for both sets of samples (~700 °C), the final YIG samples prepared by MCP method show more structural purity than those made by CN method. Higher saturation magnetization (M s ) and lower coercivity (H c ) are observed in MCP YIG sample (23.23 emu/g and 30.1 Oe) than the CN prepared YIG sample (16.43 emu/g and 44.95 Oe). The Curie temperature is measured to be 569 °C for the MCP YIG sample determined from set of M s measurement at different temperatures ranging from 80-600 K. These findings lead to significant improvement in quality of synthesized (synthetic methods) of YIG-NPs.

“…The high magnetic properties and low cytotoxicity renders these NPs possible manipulation in biomedicine application. Pure FeNPs (>100 nm) [194] or pure CoNPs (>90 nm) [195] were also reported to be generated in arc discharge over a liquid of ethylene glycol with two Fe or Co electrodes, where the ethylene glycol might play the same role as ethanol in refs. [190,191].…”

Over the past decades, a new branch of plasma research, the nanomaterial (NM) synthesis by plasma-liquid interactions (PLIs), is rapidly rising, mainly due to the recently developed various plasma sources operated from low to atmospheric pressures. The PLIs provide novel plasma-liquid interfaces where many physical and chemical processes take place. By exploiting these physical and chemical processes, various NMs ranging from noble metal nanoparticles to graphene nanosheets can be easily synthesized. The currently rapid development and increasingly wide utilization of the PLI method naturally lead to an urgent requirement for presenting a general review. This paper reviews the current status of research on plasma-liquid 2 interactions for nanomaterial syntheses. Focus is on the comprehensive understanding of the synthesis process and perceptive opinions on the present issues and future challenges in this subject.

“…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
