Adsorption of organic compounds on carbon nanotubes (CNTs), governed by interactions between molecules and CNTs surfaces, is critical for their fate, transport, bioavailability and toxicity in the environment. Here, we report a promising concentration-dependent polyparameter linear free energy relationships (pp-LFERs) model to describe the compound-CNTs interactions and to predict sorption beha...

Controlled synthesis and integration of carbon nanotubes (CNTs) remain important areas of study to develop practical carbon-based nanodevices. A method of controlling the number of CNTs synthesized depending on the size of the catalyst was characterized using nanostencil lithography, and the critical dimension for the nanoaperture produced on a stencil mask used for growing individual CNTs was ...

The Carbon nanotubes (CNTs) have been chemically functionalized with various oxygen-containing surface groups. The feature of abundant oxygen-containing surface functional groups on the functionalized CNTs is characterized by X-ray photoelectron spectroscopy and temperatureprogrammed desorption analysis. Results indicate that the functionalized CNTs have a superior adsorption capacity toward an...

Since the accidental discovery of carbon nanotubes (CNTs) during the synthesis of fullerene by Iijima (Iijima 1991), tremendous research has been done on CNTs. CNTs are under intense investigation owing to their spectacular mechanical and electrical properties (Vazquez, Georgakilas, and Prato 2002). Many ways are currently available for the production of CNTs, which include arc-discharge (Journ...

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...

Carbon nanotubes (CNTs) have attracted a great deal of interest in the development of high-performance engineering composites, due to their exceptional physical, mechanical, electronic and thermal properties. Incorporation of CNTs into polymer has shown great improvements in the functional property, however, the enhancement of the mechanical property was insignificant compared with that of micr...

Combining classical molecular dynamics simulations and density functional theory calculations, we find that cations block water flow through narrow (6,6)-type carbon nanotubes (CNTs) because of interactions between cations and aromatic rings in CNTs. In wide CNTs, these interactions trap the cations in the interior of the CNT, inducing unexpected open or closed state switching of ion transfer u...

Two different carbon nanotubes (CNTs) PR24-PS and Baytubes were functionalized by oxidation with nitric acid and further amination with gaseous NH3. Thus Au and Au-Pd nanoparticles were prepared by PVA/NaBH4 system and anchored on the surface of pristine CNTs and NCNTs (Nitrogen functionalized carbon nanotubes). TEM analysis revealed that the introduction of nitrogen functionalities improves th...

The rapid progress in developing MgB2 superconductors since its relatively recent discovery has made this material a strong competitor to other lowand high-temperature superconductor (HTS) materials for technological applications, especially in niche markets such as magnetic resonance imaging (MRI). Thanks to the lack of weak links and the two-gap superconductivity of MgB2, [2,3] a number of di...

Chemical vapor deposition of carbon nanotubes (CNTs) is the most promising method for fabricating CNTs based nanodevices [1] and sensors [2] because CNTs can be selectively grown by structuring the catalyst in a predefined arrangement. However, only dense aligned CNTs can be produced using transition metal catalysts (Fe, Co, and Ni) by plasma-enhanced chemical vapor deposition (PECVD) [3]. It i...
