Abstract
We report a simple but powerful method for engineering multi-walled carbon nanotubes (MWNTs) by using manipulation by an atomic-force microscope. The successive shell-by-shell extraction process of ultralong MWNTs allows the exposure of the innermost single-walled carbon nanotubes (SWNTs), which have diameters as small as ≈0.4 nm. The inner-shell extraction process changes the electrical characteristics of the MWNTs. Whereas the outer hollowed-out nanotubes show either metallic or semiconducting character, the innermost SWNTs of small diameter exhibit predominantly metallic transport properties.

Zero-dimensional, one-dimensional, two-dimensional and three-dimensional nanostructured materials for advanced electrochemical energy devices

TL;DR: In this paper, the authors focus on recent progress in advanced nanostructured materials (NSMs) as building blocks for EEDs (such as fuel cells, supercapacitors, and Li-ion batteries) based on investigations at the 0D, 1D, 2D and 3D NSMs.

Understanding of assembly phenomena by aromatic-aromatic interactions: benzene dimer and the substituted systems.

TL;DR: The presence of substituents on the aromatic ring, irrespective of their electron withdrawing or donating nature, leads to an increase in the binding energy, and the displaced-stacked conformations are more stabilized than the T-shaped conformers, which explains the wide prevalence of displaced stacked structures in organic crystals.

Fast DNA sequencing with a graphene-based nanochannel device

TL;DR: It is shown that as a DNA strand passes through the nanochannel, the distinct conductance characteristics of the nanoribbon allow the different nucleobases to be distinguished using a data-mining technique and a two-dimensional transient autocorrelation analysis.

Strength and breaking mechanism of multiwalled carbon nanotubes under tensile load

TL;DR: The tensile strengths of individual multiwalled carbon nanotubes (MWCNTs) were measured with a "nanostressing stage" located within a scanning electron microscope and a variety of structures were revealed, such as a nanotube ribbon, a wave pattern, and partial radial collapse.

A tunable carbon nanotube electromechanical oscillator

TL;DR: The electrical actuation and detection of the guitar-string-like oscillation modes of doubly clamped nanotube oscillators are reported and it is shown that the resonance frequency can be widely tuned and that the devices can be used to transduce very small forces.
