“…[12][13][14] Preceding studies have shown that particle size, morphology, composition, and microstructure can be tuned through processing parameters. 15 Moreover, as reactions take place in the gas phase, hazardous wet chemistry is not involved, rendering it to be a promising protocol for nanomaterial fabrication, especially for bio-application purpose.…”

An atmospheric pressure microplasma technique is demonstrated for the gas phase synthesis of Ni nanoparticles by plasma-assisted nickelocene dissociation at different conditions. The dissociation process and the products are characterized by complementary analytical methods to establish the relationship between operational conditions and product properties. The innovation is to show proof-of-principle of a new synthesis route which offers access to less costly and less poisonous reactant, a higher quality product, and a simple, continuous and pre/post treatment-free manner with chance for fine-tuning "in-flight." Results show that Ni nanoparticles with controllable magnetic properties are obtained, in which flexible adjustment of product properties can be achieved by tuning operational parameters. At the optimized condition only fcc Ni nanoparticles are formed, with saturation magnetization value of 44.4 mAm 2 /g. The upper limit of production rate for Ni nanoparticles is calculated as 4.65 3 10 23 g/h using a single plasma jet, but the process can be scaled-up through a microplasma array design. In addition, possible mechanisms for plasma-assisted nickelocene dissociation process are discussed.

“…As shown in Figure , there are two steps in the ferrocene dissociation process. First, ferrocene dissociates to Fe and (Cp)(cyclopentadienyl ring) free radicals under a temperature of 180 °C, a pressure of 1 MPa, and then (Cp) free radicals dissociate into hydrocarbon fragments (C x H x ) in the following step . Then, hydrocarbon fragments will gradually convert into carbonaceous fragments under the catalysis of iron, which can provide sufficient raw materials for the further growth of the carbon material …”

This work presents a study on the synthesis of nanostructure carbon materials by the solvothermal method. Carbon materials with different morphologies, including chain‐like solid carbon particles, hollow carbon nanospheres, and carbon nanoribbons were obtained by adjusting operating conditions. The prepared carbon nanospheres with amorphous structures include amorphous chain‐like solid carbon particles with an average particle size of 118 nm and a length range of 300–600 nm, hollow carbon nanospheres with an average diameter of ∼533 nm, and carbon nanoribbons with an average width of ∼56 nm and a length of 1000–2000 nm. In addition, a possible growth mechanism of nanostructure carbon materials prepared by the solvothermal method was discussed. The research gives a simple route to obtain carbon materials with different morphologies.

“…Excellent quality iron oxide magnetic nanoparticle can be synthesized by adopting versatile synthetic approaches include thermal decomposition, co-precipitation, micelle formation, hydrothermal and laser pyrolysis techniques. It was difficult for us to compile all this literature and we have attempted to present each synthetic approach by giving a few examples along with the corresponding formation mechanism (Ali et al, 2016;Martínez-Cabanas et al, 2016;Elrouby et al, 2017;Kandasamy, 2017;Lin et al, 2017;Liu et al, 2017;Rajiv et al, 2017;Sathya et al, 2017).…”

Substances at nanoscale, commonly known as "nanomaterials," have always grabbed the attention of researchers for hundreds of years. Among these different types of nanomaterials, magnetic nanomaterials have been the focus of considerable attention during the last two decades as evidenced by an unprecedented increase in the number of research papers focusing these materials. Iron oxide magnetic nanoparticles have occupied a vital position in imaging phenomena; as drug vehicles, controlled/sustained release phenomena and hyperthermia; atherosclerosis diagnosis; prostate cancer. In fact, these are wonderful "theranostic" agents with some under clinical trials for human use. In this review, we have attempted to highlight the advances taking place in the field of magnetic nanoparticles as theranostic agents. Extensive progress has been made in the two most important parameters, namely, control over the size and shape which decide the importance of iron oxide magnetic nanoparticles by developing suitable procedures like precipitation, co-precipitation, thermal decomposition, hydrothermal synthesis, microemulsion synthesis and plant mediated synthesis. After using a suitable synthetic route, workers encounter the most daunting task linked with the materials at nanoscale i.e., the protection against corrosion. Only properly protected iron oxide magnetic nanoparticles can be further connected to different functional systems to make building blocks for application in catalysis, biology and medicines. Finally, "theranostics" which is a combined application of imaging and drug delivery has been discussed. With all the potential uses, toxicity of the of iron oxide magnetic nanoparticles has been discussed.
