The extraordinarily high strength and stiffness of single-walled carbon nanotubes promises a myriad of unique applications, but many of these are reliant on the growth of ultralong, continuous nanotubes. A new synthetic procedure takes us a step closer to this goal. 
Mapping the transition from catalyst-pool to bamboo-like growth-mechanism in vertically-aligned free-standing films of carbon nanotubes filled with Fe3C: The key role of water
The control of carbon nanotube growth has challenged researchers for more than a decade due to the complex parameters-control necessary in the commonly used CVD approaches. Here we show that a direct
Chlorine-assisted synthesis of Fe3C-filled mm-long vertically aligned arrays of multiwall carbon nanotubes
Recent reports have shown that chlorine-radicals can be beneficial for the growth of Fe3C filled carbon nanotubes (CNTs) and the control of their filling-ratio. Here we use such chlorine-assisted
Controlling high coercivities in cm-scale buckypapers with unusual stacking of vertically aligned and randomly entangled Fe-filled carbon nanotubes
The synthesis of cm-scale buckypapers consisting of an unusual stacking of vertically aligned and randomly entangled Fe-filled carbon nanotubes is revealed through an advanced high flow-rate
Giant magnetic coercivity in Fe3C-filled carbon nanotubes
One of the major challenges in the synthesis of ferromagnetically filled carbon nanotubes is the achievement of high coercivities. Up to now the highest coercivity has been shown to be 2200 Oe at 2 K
Diameter-selective growth of single-walled carbon nanotubes with high quality by floating catalyst method.
It was found that the selective etching effects of high hydrogen flow stabilized the decomposition of ultralow CH(4) flow and considerably suppressed the deposition of amorphous carbon and small nanotubes, leading to very pure samples with high structural homogeneity suitable for further applications in practical electronic systems.
Calculation of Cutting Lines of Single-Walled Carbon Nanotubes
Abstract. Carbon nanotubes (CNs) are hexagonally shaped arrangements of carbon atoms that have been rolled into tubes with outstanding properties. Carbon nanotubes are among the stiffest and


Recent Advances in Methods of Forming Carbon Nanotubes
Since their discovery, carbon nanotubes, both single-walled and multiwalled, have been a focus in materials research. Fundamental research and application development hinge on high-quality nanotube
Ultralong single-wall carbon nanotubes
The synthesis of 4-cm-long individual single-wall carbon nanotubes at a high growth rate of 11 μm s−1 by catalytic chemical vapour deposition is reported, suggesting the possibility of growing SWNTs continuously without any apparent length limitation.
Retaining ductility
New experimental work suggests that it is possible to retain the ductility of metals after nanostructuring by activating certain deformation mechanisms.
Cobalt-catalysed growth of carbon nanotubes with single-atomic-layer walls
CARBON exhibits a unique ability to form a wide range of structures. In an inert atmosphere it condenses to form hollow, spheroidal fullerenes1–4. Carbon deposited on the hot tip of the cathode of
Single-shell carbon nanotubes of 1-nm diameter
