We report here an efficient noncovalent chemical route to dense and uniform assembly of magnetic nanoparticles onto multi-walled carbon nanotubes within a single-layer configuration. While preserving the electrical conduction behavior of the nanotube network itself, the resulting carbon nanotube derivatives exhibit a distinct superparamagnetism, and can be magnetically manipulated via a quick a...

Introduction We have previously reported downsizing ancient twistbased spinning technology for making continuous, densified nanotube yarns from multi-walled carbon nanotube (MWNT) forests [1]. Such nanotube yarns provide unique properties and property combinations. Despite this important progress, the relationship between nanotube yarn properties and component carbon nanotube properties is not ...

carbon nanotube is investigated based on an elastic multi-layer shell model with van der Waals interaction taken into consideration. The multi-walled carbon nanotube is described as an individual elastic shell and the interlayer friction is negligible between the inner and outer tubes in the proposed model. And the Donnell equations of cylindrical shells are employed to describe the nonlinear b...

A novel discrete single-walled metal-organic nanotube (JLU-MONT1) with a rare armchair (3,3) carbon nanotube topology is successfully synthesized, which is further linked by hydrogen-bonds forming a 3D supramolecular architecture. Benefiting from its anionic skeletal features and open mesoporous channels (21 Å), JLU-MONT1 exhibits extremely high efficiency and capability to adsorb carcinogens b...

Single walled carbon nanotubes were functionalized with different functionalities by simple dip coating. This fast and reproducible procedure was realized with nanotube coated electrodes for the construction of polyvalent biosensors. Three different pyrene derivatives were attached to the nanotube sidewalls by π-stacking interactions in a one-step reaction.

The present paper treats the Carbon Nanotube Field Effect Transistors (CNFETs) in terms of new development as a possible future basic element for beyond CMOS technology used in ultra high scale integration ULSI. The CNFET is studied both in physical as well as technological point of views aiming a further understanding of the limitations to high integration density. The different types of carbo...

A new molecular motor is conceptually constructed from a doublewalled carbon nanotube (DWNT) consisting of a long inner singlewalled carbon nanotube (SWNT) and a short outer SWNT with different chirality. The interaction between inner and outer tubes is the sum of the Lennard-Jones potentials between carbon atoms in inner tube and those in outer one. Within the framework of SmoluchowskiFeynman ...

Previous studies have shown that when using carbon nanotubes (CNTs) as tapping-mode AFM probes, their tilt angle with respect to vertical (denoted phi) must be close to 0 degrees to obtain high-quality images and that very poor images are obtained for phi > 30 degrees . Here we present a quantitative theoretical investigation of the effect of phi on tapping-mode AFM imaging for single-wall and ...

A novel triptycene-derived NH-bridged azacalixarene can self-assemble into an aromatic single-walled organic nanotube with large dimensions by four one-dimensional hydrogen bond chains.

The use of composite materials increases due to its exceptionally better mechanical properties compared to their individual constitutes. The use of Nano materials as one of the constitutes of composite materials adds the advantages specially of high dynamic behavior due to their dimensions of nano scale. The carbon nanotubes (CNTs) and boron nitride nanotubes (BNNTs) possess excellent mechanica...
