Methods of using carbon nanotubes as filter media to remove aqueous heavy metals [PDF]

, 2012
Although carbon nanotubes (CNTs) are well known to have a strong affinity to various heavy metals in aqueous solution, little research has been dedicated to exploit their use in fixed-bed water treatment systems (e.g., trickling filters).

Carbon Nanotube Thermal Transport: Ballistic to Diffusive

, 2005
We propose to use l_0/(l_0+L) for the energy transmission covering both ballistic and diffusive regimes, where l_0 is mean free path and L is system length. This formula is applied to heat conduction in carbon nanotubes (CNTs).

Electronic transport in metallic carbon nanotubes with mixed defects within the strong localization regime

, 2017
We study the electron transport in metallic carbon nanotubes (CNTs) with realistic defects of different types. We focus on large CNTs with many defects in the mesoscopic range.

A study concerning the pretreatment of CNTs and its influence on the performance of NIB/CNTs amorphous catalyst [PDF]

Journal of the Serbian Chemical Society, 2006
As prepared carbon nanotubes were pretreated with nitric acid (CNTs-HNO3) or ammonia (CNTs-NH3). Fourier transform infrared spectroscopy (FTIR) measurements showed that the surface of the nanotubes was functionalized with carboxylic and hydroxyl ...

Carbon supported CdSe nanocrystals [PDF]

, 2008
Insights to the mechanism of CdSe nanoparticle attachment to carbon nanotubes following the hot injection method are discussed. It was observed that the presence of water improves the nanotube coverage while Cl containing media are responsible for the ...

Effect of carbon nanotube (CNT) functionalization in epoxy-CNT composites [PDF]

Nanotechnology Reviews, 2018
Abstract The effect of carbon nanotube (CNT) functionalization in altering the properties of epoxy-CNT composites is presented. The presence of functional groups effectively influenced the colloidal behavior of CNTs in the precursor epoxy resin and the hardener triethylenetetramine (TETA), which affected the synthesis process and ...

Hygrothermal environment effect on the critical buckling load of FGP microbeams with initial curvature integrated by CNT-reinforced skins considering the influence of thickness stretching

Nanotechnology Reviews, 2021
Due to the need for structures with refined properties to bear against different loading conditions, recently, carbon nanotubes (CNTs) have been used widely to reinforce them. The extremely high stiffness of CNTs makes them significant as one of the best

Functionalization of carbon nanotubes with -CHn, -NHn fragments, -COOH and -OH groups

, 2013
We present results of extensive theoretical studies concerning stability, morphology, and band structure of single wall carbon nanotubes (CNTs) covalently functionalized by -CHn(for n=2,3,4),-NHn(for n=1,2,3,4),-COOH and -OH groups. Our studies are based
