TLDR
In this article, the benefits and challenges of using plasma-based systems in nanofabrication of nanostructured silicon films, low-dimensional semiconducting quantum structures, ordered carbon nanotip arrays, highly crystalline ${\mathrm{TiO}}_{2}$ coatings, and nano-structured hydroxyapatite bioceramics are discussed.Abstract:
The underlying physics of the application of low-temperature, low-pressure reactive plasmas in various nanoassembly processes is described. From the viewpoint of the ``cause and effect'' approach, this Colloquium focuses on the benefits and challenges of using plasma-based systems in nanofabrication of nanostructured silicon films, low-dimensional semiconducting quantum structures, ordered carbon nanotip arrays, highly crystalline ${\mathrm{TiO}}_{2}$ coatings, and nanostructured hydroxyapatite bioceramics. Other examples and future prospects of plasma-aided nanofabrication are also discussed.read more

TL;DR: In this paper, the most important mechanisms of generation and transport of the key species in the plasmas of atmospheric-pressure plasma jets and other non-equilibrium atmospheric pressure plasms are introduced and examined from the viewpoint of their applications in plasma hygiene and medicine and other relevant fields.

Dynamics of an atmospheric pressure plasma plume generated by submicrosecond voltage pulses
XinPei Lu,Mounir Laroussi +1 more
TL;DR: In this paper, a model based on photoionization is used to explain the propagation kinetics of the plasma bullet under low electric field conditions, showing that the plume is in fact a small bullet-like volume of plasma traveling at unusually high velocities.

Microplasmas for nanomaterials synthesis
TL;DR: Microplasmas have attracted a tremendous amount of interest from the plasma community because of their small physical size, stable operation at atmospheric pressure, non-thermal characteristics, high electron densities and non-Maxwellian electron energy distributions as discussed by the authors.

Plasma nanoscience: from nano-solids in plasmas to nano-plasmas in solids
TL;DR: The unique plasma-specific features and physical phenomena in the organization of nanoscale soild-state systems in a broad range of elemental composition, structure, and dimensionality are critically reviewed in this paper.

Plasma Nanoscience: from Nano-Solids in Plasmas to Nano-Plasmas in Solids
TL;DR: In this paper, a unified conceptual framework based on the control of production, transport, and self-organization of precursor species is introduced and a variety of plasma-specific non-equilibrium and kinetics-driven phenomena across the many temporal and spatial scales is explained.

Helical microtubules of graphitic carbon
TL;DR: Iijima et al. as mentioned in this paper reported the preparation of a new type of finite carbon structure consisting of needle-like tubes, which were produced using an arc-discharge evaporation method similar to that used for fullerene synthesis.

Cobalt-catalysed growth of carbon nanotubes with single-atomic-layer walls
TL;DR: In this paper, it was shown that covaporizing carbon and cobalt in an arc generator leads to the formation of carbon nanotubes which all have very small diameters (about 1.2 nm) and walls only a single atomic layer thick.

TL;DR: Time-resolved, high-resolution in situ transmission electron microscope observations of the formation of carbon nanofibres from methane decomposition over supported nickel nanocrystals show that metallic step edges act as spatiotemporal dynamic growth sites and may be important for understanding other types of catalytic reactions and nanomaterial syntheses.
