In this paper, a simple and reproducible approach for attaching the multi-wall carbon nanotubes (MWNTs) to the apex of the atomic force microscope probe has been proposed. For this purpose, the dielectrophoresis method was applied due to its simple performance, cheapness and reliability. In this method, various parameters such as voltage, frequency, concentration of carbon nanotubes solution an...
We have demonstrated near-edge X-ray absorption fine structure (NEXAFS) spectroscopy as a particularly useful and effective technique for simultaneously probing the surface chemistry, surface molecular orientation, degree of order, and electronic structure of carbon nanotubes and related nanomaterials. Specifically, we employ NEXAFS in the study of single-walled carbon nanotube and multi-walled...
Hydroxyl functional poly(amidoamine) dendron wedges have been reacted with the surface of multi-walled carbon nanotubes and used for templating silver nanoparticles.
In this work, the optical properties dependence of Multi-Walled Carbon Nanotubes (MWNT) on concentration was discussed. MWNT samples were prepared in polypyrrole by an electrochemical polymerization of monomers, in the presence of different concentrations of MWNTs, using Sodium Dodecyl-Benzen-Sulfonate (SDBS) as surfactant at room temperature. The nonlinear refractive and nonlinear absorbtion i...
Background: Synthetic dyes are serious pollutants and wide ranges of methods have been employed for their removal from aquatic systems. We studied the adsorption of "Nile blue A" (NBA), an anionic dye, from aqueous solution by oxidized multi-walled carbon nanotubes (MWCNTs). Methods: Scanning electron microscope and Fourier transform infrared spectroscopy were used to characterize ...
Sidewall functionalized multi-walled carbon nanotubes can be covalently bound parallel to a silicon surface via a self-assembled acid-terminated monolayer used as an organic molecular glue.
Synthesis of oriented arrays of TiO2 nanorods via a high temperature conversion of carbon nanotubes.
Oriented arrays of both rutile and anatase nanorods have been synthesised in a two-stage process, employing multi-walled carbon nanotubes as the initial structural template.
Magnetic silica nanoparticle functionalized multi-walled carbon nanotubes (MS-MWNTs) were prepared, characterized and used for the convenient, rapid and efficient separation of trace aromatic compounds.

Background and purpose: Continuous input of antibiotics to the environment causes many problems such as antibiotic resistance in pathogenic microorganisms. Therefore, researchers are aiming to find solutions to reduce antibiotics in hospital effluents and polluted waters. Amoxicillin is an antibiotic which is widely used to treat infections. Due to inappropriate use it enters the wastewater and...
