A novel, simple method has been developed for the preconcentration of Cu(II) based on the adsorption of its Schiff’s cupferron complex on a multi walled carbon nanotubes (MWCNTs) onto C18 cartridge .A new technique using a solid phase extraction (SPE) cartridge with modified Schiff’s Cupferron complex on a multi walled carbon nanotubes (MWCNTs) onto C18 cartridge as sorbent was developed for th...

introduction: the therapeutic potential of anandamide (aea) for the neurological disorders may be negatively affected by its short half-life or poor solubility. the superior properties of carbon nanotubes (cnts) for controlled drug delivery, prompted us to design aea-cnts complex and assess its effect in in vitro model of ischemic stroke. methods: in this experimental study, a multi-walled cnts...

Thermoplastic polyolefin (TPO) has gained considerable attention because of having a combination rubbery and thermoplastic properties ease production. Their excellent weather resistance, low density, relatively cost make them attractive materials for the automotive, electrical, footwear industries membranes water treatment. main shortcomings are poor mechanical properties, especially at tempera...

Carbon nanostructured materials in general and carbon nanotubes in particular exhibit remarkable and unique properties that make them promising candidates for a wide range of applications. In the field of sensors, for example, carbon-based materials such as fullerene (C60) [1], three-dimensionally ordered macroporous (3DOM) carbon [2], and single-walled carbon nanotubes (SWCNTs) [3] have been u...

This study indicated that multi-walled carbon nanotubes (MWCNTs)-epoxy composites can be used as effective lightweight shielding materials. The measurement results showed that highest EMI SE of 23.4 dB at 8 GHz was obtained for nanocomposite with 1 wt% MWCNTs. Dielectric properties and electrical conductivity values were supplemented by microscopic studies.

one of the most important applications of carbon nanotubes (cnts) is as reinforcement of metal matrix composites, because of their excellent mechanical properties. in this study, al-tio2-multi walled carbon nanotubes (mwcnts) nanocomposite is fabricated using isostatic pressing followed by hot extrusion. mechanical alloying is used to mix powders of aluminium, tio2 and mwcnts. tio2 with the amo...

Toluene and benzene were eliminated using multi-walled carbon nanotubes (MWCNTs). In order to investigate influence of acid treatment on the MWCNTs adsorption capacities, the MWCNTs were functionalized by nitric acid (10 M) under reflux conditions for 2 h. Fourier transform infrared (FTIR) and Raman spectroscopy were employed to confirm the formation of functional groups on the nanotubes su...

the present study was carried out to investigate the potential of carboxylate group functionalized multi-walled carbon nanotubes (mwcnt−cooh) adsorbent for the removal of methyl orange (mo) textile dye from aqueous solutions. the effects of ph, shaking time and temperature on adsorption capacity were studied; the contact time to obtain equilibrium at 298 ˚k was fixed at 25 min. the effect of te...

In this study we report the preparation of nanohybrid dispersant molecules based on pyrene and polyhedral oligomeric silsesquioxanes for non-covalent functionalization of multi-walled carbon nanotubes (MWCNTs). The prepared dispersant improves the dispersion of MWCNTs in organic solvents with very different polarities such as tetrahydrofuran, toluene, and n-hexane. The functionalized MWCNTs wer...
