Carbon nanotube (CNT) membranes allow the mimicking of natural ion channels for applications in drug delivery and chemical separation. Double-walled carbon nanotube membranes were simply functionalized with dye in a single step instead of the previous two-step functionalization. Non-faradic electrochemical impedance spectra indicated that the functionalized gatekeeper by single-step modificatio...

In 1991 Iijima [Iijima, 1991] presented transmission electron microscopy observations of elongated and concentric layered microtubules made of carbon atoms, nowadays which were called carbon nanotubes (CNTs). In order to understand the structure of a carbon nanotube, it can be first imagined as a rolled up sheet of graphene with planar-hexagonal arrangement of carbon atoms distributed in a hone...

Chemical Functionalization is a technique used to increase the dispersion and solubility of single-walled carbon nanotube (SWCNT). Functionalization of a (10, 0) zigzag nanotube segment containing 80 C atoms was investigated with the aide of spinunrestricted density functional theory (DFT). The (10, 0) was funtionalized with three organic acid groups: (a) carboxylic acid, (b) aromatic dicarboxy...

   To fabricate a defect free and high performance mixed matrix membrane (MMM), one approach is the functionalization of inorganic nanofillers (as dispersed phase) in the organic polymer matrix (as continuous phase) to modify the interactions between two phases.  For this purpose,, raw multi-walled carbon nanotubes (rMWCNTs) were purified by acid mixture (HNO3/H2SO<sub...

In this study, kinetics and mechanism of the sulfur dioxide adsorption on the single-walled carbon nanotubes (CNT) are investigated. Three single-walled carbon nanotubes, including the armchair (6,6), chiral (6,5) and zigzag (6,0) CNTs were chosen as the models and the different orientations of SO2 molecule relative to the CNT axis were considered. The B3LYP functional within the 6-3...
