“…34 Self-irradiation with 100 eV C + ions was used for making nanotube-amorphous diamond nanocomposites 35 in which conducting mats of SWNTs were protected against wear by 50 nm amorphous diamond films. Experiments also indicate that magnetized-plasma ion irradiation can be used for encapsulating fullerenes 376 and intercalating cesium inside SWNTs ͑Ref. 377͒ via irradiation-induced defects in the tube walls.…”

A common misconception is that the irradiation of solids with energetic electrons and ions has exclusively detrimental effects on the properties of target materials. In addition to the well-known cases of doping of bulk semiconductors and ion beam nitriding of steels, recent experiments show that irradiation can also have beneficial effects on nanostructured systems. Electron or ion beams may serve as tools to synthesize nanoclusters and nanowires, change their morphology in a controllable manner, and tailor their mechanical, electronic, and even magnetic properties. Harnessing irradiation as a tool for modifying material properties at the nanoscale requires having the full microscopic picture of defect production and annealing in nanotargets. In this article, we review recent progress in the understanding of effects of irradiation on various zero-dimensional and one-dimensional nanoscale systems, such as semiconductor and metal nanoclusters and nanowires, nanotubes, and fullerenes. We also consider the two-dimensional nanosystem graphene due to its similarity with carbon nanotubes. We dwell on both theoretical and experimental results and discuss at length not only the physics behind irradiation effects in nanostructures but also the technical applicability of irradiation for the engineering of nanosystems.

“…In the early 2000s, the plasma-ion irradiation method enabled various atoms and molecules to be encapsulated inside SWNTs (C 60 , Cs, DNA@SWNTs) (Jeong et al 2001, and vertically standing 2D nanosheets, i.e., CNWs were grown by microwave PECVD (Wu et al 2002). Subsequently, DC dischargesustained PECVD made it possible to grow MWNTs at temperatures as low as 120°C (Hofman et al 2003), and the individual growth of SWNTs was realized by PECVD using a downstream diffusion plasma .…”

Since the discovery of fullerenes more than three decades ago, new kinds of nanoscale materials of carbon allotropes called ''nanocarbons'' have so far been discovered or synthesized at successive intervals as cases such as carbon nanotubes, carbon nanohorns, graphene, carbon nanowalls, and a carbon nanobelt, while nanodiamonds were actually discovered before then. Their attractively excellent mechanical, physical, and chemical properties have driven researchers to continuously create one of the hottest frontiers in materials science and technology. While plasma states have often been involved in their discovery, on the other hand, plasma-based approaches to this exciting field originally hold promising and enormous potentials for advancing and expanding industrial/biomedical applications of nanocarbons of great diversity. This article provides an extensive overview on plasma-fabricated nanocarbon materials, where the term ''fabrication'' is defined as synthesis, functionalization, and assembly of devices to cover a wide range of issues associated with the step-by-step plasma processes. Specific attention has been paid to the comparative examination between plasma-based and non-plasma methods for fabricating the nanocarobons with an emphasis on the advantages of plasma processing, such as low-temperature/large-scale fabrication and diversitycarrying structure controllability. The review ends with current challenges and prospects including a ripple effect of the nanocarbon studies on the development of related novel nanomaterials such as transition metal dichalcogenides. It contains not only the latest progress in the field for cutting-edge scientists and engineers, but also the introductory guidance to non-specialists such as lower-class graduate students.& Rikizo Hatakeyama

“…The other example was proposed by a Japanese consortium and consists of using collisions of accelerated atoms or molecules from a plasma generated between a grounded electrode and a stainless steel plate on which SWCNTs were previously deposited. Nanotubes were filled with fullerenes [90,91] and Cs [91] this way. Oxidized and therefore opened SWCNTs were used for purity purposes only, and the method should work with raw (i.e.…”

Whilst fullerene and related materials are the most inserted molecules in carbon nanotubes (CNTs), other molecular species including Zn-diphenylporphyrin (i.e. Zn-DPP) [1], orthocarborane [2,3], metallocenes [4,5], octasiloxane [6] and squarylium dye [7], among others have been encapsulated within either single-, double-or multiple walled carbon nanotubes (SWCNTs, DWCNTs and MWCNTs, respectively) and directly imaged by either high resolution transmission electron microscopy (HRTEM) or related techniques. In tandem with these studies, one-dimensional (1D) nanowires of a wide variety of materials including multiplets of polymeric iodine chains [8,9]
