Bamboo-like carbon nanotubes are members of the carbon nanotubes (CNTs) family, whose structure is made up of separated hollow compartments and bamboo knots. Due to the peculiar structure of the CNTs species, the growth mechanism and related features have been widely investigated. Bamboo-like carbon nanotubes are widely applied in several fields, such as sensors, adsorbents, catalysts, and lith...

The aggregation and dispersion behaviors of carbon nanotubes (CNTs) can regulate the environmental spread and fate of CNTs, as well as the organic pollutants adsorbed onto them. In this study, multi-walled carbon nanotubes (MWNTs) and single-walled carbon nanotubes (SWNTs) were surface modified with humic acids from different sources and with surfactants of different ionic types. The dispersion...

We report rational design of amphiphilic polymers capable of making carbon nanotubes (CNTs) highly water dispersible and resistant to biofouling; such CNTs can be conjugated with bioactive molecules so as to be potential drug delivery vehicles.

Carbon nanotubes (CNTs) have been readily functionalized by microwave activation using two different reactions affording functional derivatives characterized by two orthogonally protected amino groups. The doubly functionalized CNTs can serve as multipurpose, versatile synthons in materials science and biological applications.

The synthesis of nitrogenated carbon nanotubes (N-CNTs) with up to 6.1 wt% N, via the use of pyridine as the nitrogen containing carbon precursor, can provide a facile route to significantly enhance the low intrinsic specific capacitance of carbon nanotubes. The nitrogen functionalities determine this, at least, five-fold increase of the specific capacitance.

In this paper at first a brief review of carbon nanotubes (CNTs) is given and then an extensive survey of CNTFET (carbon nanotube field effect transistor) based logic circuits are discussed with the most recently reported CNTFET logic circuits. Keywords— MOSFETs, technology scaling, CNTFETs, carbon nanotubes (CNT), chiriality.

This paper preliminarily investigates the general transport properties (i.e., water sorptivity, water permeability, and gas permeability) of carbon-nanotube/cement composites. Carboxyl multi-walled carbon nanotubes (MWNTs) are dispersed into cement mortar to fabricate the carbon nanotubes (CNTs) reinforced cement-based composites by applying ultrasonic energy in combination with the use of surf...

The high surface area, size, hollow geometry and chemical inertness remarkable properties of CNTs make them attractive for demanding applications in the field of gas sensing. To date studies on possible applications of CNTs have been focused either on individual single-walled carbon nanotubes (SWNTs) as sensitive materials towards O2, NO2 and NH3 [1-4] or on multi-walled carbon nanotubes (MWNTs...

one of the most important applications of carbon nanotubes (cnts) is as reinforcement of metal matrix composites, because of their excellent mechanical properties. in this study, al-tio2-multi walled carbon nanotubes (mwcnts) nanocomposite is fabricated using isostatic pressing followed by hot extrusion. mechanical alloying is used to mix powders of aluminium, tio2 and mwcnts. tio2 with the amo...

Carbon nanotubes (CNTs) are high aspect ratio allotropes of carbon. Because of their unique physical and chemical characteristics, they are nominated for a vast variety of applications in the biomedical field. Their very low solubility is the only problem of them which is solved by different methods of Functionalization. After discoveries in the last few years of the capacity of CNTs to penetra...
