The superior mechanical properties of carbon nanotubes (CNTs) mean they have been regarded as a new material with the potential to revolutionize and enable many advanced technologies. CNTs have extremely high tensile strength ( 150 GPa), high modulus ( 1 TPa), large aspect ratio, low density, good chemical and environmental stability, and high thermal and electrical conductivity. These superior...

In spite of much research progress in the science and synthesis of carbon nanotubes (CNTs), control over the location and orientation of CNTs on substrates remains a major challenge. A key breakthrough was the synthesis of vertically aligned CNT (VA-CNT) arrays using thermal chemical vapor deposition (CVD) and plasma-enhanced CVD, where the CNTs self-orient perpendicular to the substrate surfac...

We present a novel micromechanics-based phase field approach to model crack initiation and propagation in carbon nanotube (CNT) based composites. The constitutive mechanical fracture properties of the nanocomposites are first estimated by mean-field homogenisation approach. Inhomogeneous dispersion CNTs is accounted for means equivalent inclusions representing agglomerated CNTs. Detailed parame...

carbon nanotubes (cnts), nowadays, are one of the important nanomaterials that can be produce with different methods such as chemical vapor deposition (cvd). growing of cnts via cvd method can be influenced by several operating parameters that can affect their quality and quantity. in this article, the effects of inlet gas mixture temperature on cnt’s local growth rate, total production, and le...

A nitrogen-doped mesoporous carbon containing a network of carbon nanotubes (CNTs) was produced for use as a catalyst for the oxygen reduction reaction (ORR). SiO2 nanoparticles were decorated with clusters of Fe atoms to act as catalyst seeds for CNT growth, after which the material was impregnated with aniline. After polymerization of the aniline, the material was pyrolysed and the SiO2 was r...

Carbonated melamine foam (CMF) with a three-dimensional (3D) inner connected network is considered as one of the promising candidates to fabricate electromagnetic interference (EMI) shielding materials. To further improve EMI performance, CMF based hybrids structure by combination SiO2 and in-situ growth carbon nanotubes (CNT) have been synthesized for preparing polydimethylsiloxane (PDMS) comp...

Carbon nanotubes (CNTs) are often processed in suspended form and therefore a release of CNT-suspensions into the aquatic environment is plausible. In this study, the behaviour of two physico-chemically very different CNT types in the presence of varying, environmentally relevant calcium-containing media was investigated, including the long-term colloidal stability and the sedimentary structure...

The introduction of new materials and processes to microfabrication has, in large part, enabled many important advances in microsystems, lab-on-a-chip devices, and their applications. In particular, capabilities for cost-effective fabrication of polymer microstructures were transformed by the advent of soft lithography and other micromolding techniques (1, 2), and this led a revolution in appl...

We have witnessed tremendous growth in the area of nanomaterials for the past three decades. The discovery of fullerenes by Kroto et al. in 1985, was followed by the isolation of some more novel carbon nanomaterials, new allotropes of carbon. These include carbon nanotubes (CNTs) obtained by Iijima in 1991 and graphene isolated by simple exfoliation of graphite with a scotch paper by Novoselov ...
