In the present paper, the nonlinear response of carbon nanotubes has been investigated by using the dielectric constants of these nanotubes evaluated by using the Maxwell-Garnett Effective Medium Theory. SWNT’s deposited on the tip of a dielectric substrate show a drastic change in reflectance and transmittance of the incident laser light due to change in their nonlinearity and optical constants. This property may be further used for developing all-optical switching devices.

Kinetic Sorption

In this study, non-irradiated and weathered multiwalled carbon nanotubes (MWCNTs) obtained through irradiation, were studied as adsorbents for BPA, both nanomaterials being characterized before and after the adsorption process. The objectives of our investigation were to compare the characteristics of non-irradiated and irradiated MWCNTs, to evaluate the adsorption capacity of BPA by pristine and irradiated MWCNTs and to determine the variation of the kinetic, sorption and thermodynamic parameters during sorption process using both sorbents.
