In order to increase gas storage capacity such as hydrogen and methane, various wt% of cobalt were decorated on the surface of MWCNTs which was already treated nitric and sulfuric acids to provide functional groups on the surface of MWCNTs. The characteristic peak of SO4 in FT-IR spectrum was at 1220 cm, which was resulting from sulfuric acid treatment. This peak implies that acid treatment con...

A fiber coating from polyaniline (PANI) was electrochemically prepared and employed for Solid phase micreoextraction (SPME). The PANI film was directly electrodeposited on the platinum wire surface using cyclic voltametry (CV) technique. The same method was applied for the preparation of SPME fiber coated by polyaniline multiwalled carbon nanotubes (PANI/MWCNTs) composite. The concentration of ...

Abstract Safety assessment of cellulose nanofibrils (CNFs) is required to accelerate the utilization these materials in industrial applications. The present study aimed characterize effects on rat pulmonary inflammation over a period 90 days following intratracheal instillation three types CNFs or multi-walled carbon nanotubes (MWCNTs) at doses 0.5, 1.0, 2.0 mg/kg. inflammatory responses induce...

Oxidized low-density lipoprotein (ox-LDL) is assumed to be a major causal agent in hypercholesteraemia-induced atherosclerosis. Because the proliferation of lipid-loaden macrophages within atherosclerotic lesions has been described, we investigated the dependence of macrophage proliferation on the inhibition of inducible nitric oxide synthase (iNOS) by hypochlorite oxidized LDL. Ox-LDL induces ...

background: there is evidence that cd36 promotes foam cell formation through internalizing oxidized ldl (ox-ldl) into macrophages therefore, it plays a key role in pathogenesis of atherosclerosis. in addition, cd36 expression seems to be mediated by nuclear receptor peroxisome proliferator-activated receptor gamma (ppar-γ). the aim of the present study was to evaluate and compare the effect of ...

Iron-filled multiwall carbon nanotubes (Fe@MWCNTs) were functionalized toward a variety of potential magnetic resonance imaging contrast agents. Oxidized Fe@MWNCTs were covered with PEG5000 via direct esterification or using acyl chloride derivatives. Alternatively, the latter were functionalized with an aminophenol ligand (Fe@O-MWCNT-L). Moreover, pristine Fe@MWCNTs were functionalized with N-...

The creep and dynamic mechanical behavior of natural fiber/epoxy composites using functionalized multiwalled carbon nanotubes (MWCNTs) modified matrix were investigated. 0.4 wt% of MWCNTs functionalized with carboxylic acid groups (MWCNTs-COOH) were dispersed in epoxy and three-phase multiscale hybrid composites were processed by hot press. Natural fiber/epoxy two-phase composites without MWCNT...

Oxidized multi-walled carbon nanotubes (MWCNTs) with different oxygen contents were investigated for the adsorption of tetracycline (TC) from aqueous solutions. As the surface oxygen content of the MWCNTs increased, the maximum adsorption capacity and adsorption coefficient of TC increased to the largest values and then decreased. The relation can be attributed to the interplay between the nano...
