A water soluble naphthalenebisimide derivative (NBI) was synthesized and probed to individualize, suspend, and stabilize single wall carbon nanotubes (SWCNTs). Besides a comprehensive photophysical and electrochemical characterization of NBI, stable suspensions of SWCNTs were realized in buffered D2O. Overall, the dispersion efficiency of the NBI surfactant was determined by comparison with nap...

Single-walled carbon nanotubes (SWCNTs) have been amidated by hydrothermal treatment with different aliphatic amines. The amido groups modified on the surface of the SWCNTs were characterized by Fourier transform infrared spectroscopy. The electrooxidation of nitric oxide (NO) at the modified electrodes of amidated SWCNTs was investigated. The modified electrodes of amidated SWCNTs exhibited di...

Studies have been performed on both as-received and chemically oxidized single-walled carbon nanotubes (SWCNTs) grown by two different growth methods to better understand the preferential association of the oligodeoxyribonucleotide T30 (ODN) with SWCNTs. Samples of T30 ODN:SWCNT were examined under ambient conditions using non-contact scanning probe microscope (SPM) techniques. The resulting im...

Band gap opening and modulating are critical in dictating the functionalities of single walled carbon nanotubes (SWCNTs) in a broad array of nano-devices. Using first-principles density functional theory calculations, a class of semiconducting armchair SWCNTs with a distinctive BN line defect are studied, showing a super capacity to open the band gap of (4, 4) SWCNT to as large as 0.86 eV, whil...

Addition of polydispersed acid functionalised single-walled carbon nanotubes (AF-SWCNTs) significantly suppressed alloimmune cytotoxic T cell (CTL) response generated in a mixed lymphocyte reaction (MLR) between spleen cells from C57BL/6 (H-2(b)) and BALB/c (H-2(d)) mice. AF-SWCNTs treatment also decreased CD69 expression, enhanced apoptotic response in T cells and reduced significantly the rec...

In the present research, dynamic responses of multilayer functionally graded graphene platelets reinforced composite (FG-GPLRC) spherical panels under blast loading are studied. Three-dimensional elasticity theory is employed to derive governing equations. The distribution (GPLs) in each layer uniform and random with a constant weight fraction. GPLs concentration across panel thickness may be o...

The single-walled carbon nanotube (SWCNT)-molecularly imprinted powder (MIP) composites in this paper were prepared by mixing SWCNTs with MIPs. The structure and micrograph of the as-prepared SWCNTs-MIPs samples were characterized by XRD and TEM. The gas-sensing properties were tested through indirect-heating sensors based on SWCNT-MIP composites fabricating on an alumina tube with Au electrode...

Electronic characteristics of a single-walled carbon nanotube (SWCNT) strongly depend on minor variations in its atomic arrangement, specifically chirality. Therefore, precise control over nanotube chirality is highly desired for their application. Theoretically, SWCNTs with different structures have different chemical reactivities, which can be further used for their chirality selection. Here,...

This article deals with evaluating the frequency response of functionally graded carbon nanotube reinforced magneto-electro-elastic (FG-CNTMEE) plates subjected to open and closed electro-magnetic circuit conditions. In this regard finite element formulation has been derived. The plate kinematics adjudged via higher order shear deformation theory (HSDT) is considered for evaluation. equations m...
