DIFFERENCES IN CYTOCOMPATIBILITY BETWEEN MWCNTs AND CARBOXYLIC FUNCTIONALIZED MWCNTs
Functional Materials Letters, 2013Influence of carboxylic functionalization on the cytocompatibility of multiwalled carbon nanotubes (MWCNTs) was investigated in this work. Water contact angle assay showed that the surface of MWCNTs-containing carboxyl (MWCNTs-COOH) became much more hydrophilic compared with pure MWCNTs. In cell-adhesion assays, two cell lines, mouse fibroblast cells (

Influence of MWCNTs additives on the thermal conductivity of HA–MWCNTs composite
Low Temperature Physics, 2023Possible changes in the temperature dependence of the coefficient of thermal conductivity of the hydroxyapatite (HA) composite with multi-walled carbon nanotubes (MWCNTs) with small amounts of MWCNTs additives (0.5 wt%) were analyzed in comparison with the dependence of HA matrix without additives.

High electroactivity performance in Pt/MWCNT and PtNi/MWCNT electrocatalysts
International Journal of Hydrogen Energy, 2013Abstract This work presents the synthesis, characterization and electrochemical evaluation of electrocatalysts for PEM fuel cells base on Pt and Pt–Ni nanoparticles over multi-walled carbon nanotubes (MWCNT). The MWCNT were synthesized by spray pyrolysis of toluene, using ferrocene and nickelocene as catalytic agents.

Study the nonlinear behavior of MWCNTs and ZnO/Se/MWCNTs
AIP Conference Proceedings, 2019MWCNTs and hybrid nanocomposite ZnO/Se/MWCNTs have been prepared via Solvothermal technique using Parr reactor at the temperature 180°C and SeCl2 as a catalyst. The obtained MWCNTs and ZnO/Se/MWCNTs are investigated using the FE-SEM, XRD, UV-VIS Spectroscopy and Z-Scan. The novelty of this research is studying the nonlinear optical properties for these

Vertically aligned laser sliced MWCNTs
Nanoscale, 2019Applications of multi-walled carbon nanotubes (MWCNTs) benefit from the availability of specific lengths of the material while keeping the outer walls pristine, for example, for applications requiring vertically aligned tubes.

Gas sensing properties of MWCNT/ZnO and MWCNT/ZnO/In2O3 nanostructures
AIP Conference Proceedings, 2020Nanostructures based on multi-walled carbon nanotubes (MWCNT) and zinc oxides (ZnO) and indium (In2O3) were obtained and studied. The morphology and elemental composition of MWCNT/ZnO and MWCNT/ZnO/In2O3 nanostructures were investigated by scanning electron microscopy (SEM).

Abstract The migration of multi-walled carbon nanotubes (MWCNTs) from the thermodynamically favored polycarbonate (PC) phase to the acrylonitrile-butadiene-styrene (ABS) phase is observed when PC/MWCNT masterbatch is diluted with PC and ABS by melt mixing for 5 min with 70% of ABS having relatively high rubber content. The migration is explained by a

Raman spectra of MWCNTs and MWCNT-based H2-adsorbing system
Carbon, 2002Abstract Raman spectra were taken with an UV–vis Raman system on two types of multiwalled carbon nanotubes (MWCNTs, CH4-based) and MWCNTs (CO-based), grown catalytically with CH4 and CO as the carbon sources, respectively, and their H2-adsorbing systems. The strongest peak at 1580 cm−1 and the second-strongest band at 1416 cm−1 could be attributed to

Effect of MWCNT Composition on the Hardness of PP/MWCNT Composites
Materials Today: Proceedings, 2017Abstract Polypropylene(PP) composites were fabrication with minor(5wt% and 10wt%) compositions ofMulti-Walled Carbon Nanotubes(MWCNTs) using solvent mixing method. These composites were characterized to evaluate the effect of MWCNTs on the mechanical properties of PP.
