Helical microtubules of graphitic carbon
TLDR
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.Abstract:
THE synthesis of molecular carbon structures in the form of C60 and other fullerenes1 has stimulated intense interest in the structures accessible to graphitic carbon sheets. Here I report the preparation of a new type of finite carbon structure consisting of needle-like tubes. Produced using an arc-discharge evaporation method similar to that used for fullerene synthesis, the needles grow at the negative end of the electrode used for the arc discharge. Electron microscopy reveals that each needle comprises coaxial tubes of graphitic sheets, ranging in number from 2 up to about 50. On each tube the carbon-atom hexagons are arranged in a helical fashion about the needle axis. The helical pitch varies from needle to needle and from tube to tube within a single needle. It appears that this helical structure may aid the growth process. The formation of these needles, ranging from a few to a few tens of nanometres in diameter, suggests that engineering of carbon structures should be possible on scales considerably greater than those relevant to the fullerenes. On 7 November 1991, Sumio Iijima announced in Nature the preparation of nanometre-size, needle-like tubes of carbon — now familiar as 'nanotubes'. Used in microelectronic circuitry and microscopy, and as a tool to test quantum mechanics and model biological systems, nanotubes seem to have unlimited potential.read more

Carbon nanotube-modified electrodes for the simultaneous determination of dopamine and ascorbic acid.
TL;DR: The voltammetric separation of dopamine and ascorbic acid was studied with cyclic voltammetry and indicated that the resolution of DA and AA was mainly attributable to the stereo porous interfacial layer formed from aggregated pores and inner cavities of the carbon nanotubes.

Free vibration and elastic buckling of functionally graded porous beams reinforced by graphene platelets
TL;DR: In this article, a multilayer beam model with material parameters varying across layers to achieve graded distributions in both porosity and nanofillers was proposed with a particular focus on the effects of weight fraction, distribution pattern, geometry and size of GPL reinforcements on the free vibration and buckling behaviors of the nanocomposite beam with different metal matrixes and porosity coefficients.

Metal-Nanocluster-Filled Carbon Nanotubes: Catalytic Properties and Possible Applications in Electrochemical Energy Storage and Production
TL;DR: In this paper, a template-synthesized carbon tubule is used to construct a monodisperse graphitic carbon nanotubule membrane, which can then be filled with nanoparticles of electrocatalytic materials (i.e., Pt, Ru, Pt/Ru).

The top 100 papers
TL;DR: To mark the 50th anniversary of the Science Citation Index, Nature asked Thomson Reuters, which now owns the SCI, to list the 100 most highly cited papers of all time, and revealed some surprises, not least that it takes a staggering 12,119 citations to rank in the top 100 — and that many of the world's most famous papers do not make the cut.

Growth, Structure, and Properties of Graphite Whiskers
TL;DR: Graphite whiskers have been grown in a dc arc under a pressure of 92 atmospheres of argon and at 3900°K as discussed by the authors, with recoverable lengths up to 3 cm. They are embedded in a solid matrix of graphite which builds up by diffusion of carbon vapor from the positive to the negative electrode.
