Preparation, Characterization and Electrical Conductivity of Chitosan-C 30B/MWCNT Nanocomposite FilmsBy Dillip Kumar Behera, Kampal Mishra, P.L. Nayak
Abstract: In this research programme organoclay clay Cloisite 30B (C 30B) and Multi walled carbon nanotubes (MWCNTs) were successfully blended with the biopolymer Chitosan (CS). The polymer nanocomposites were characterised by various techniques like Fourier Transmission Infrared spectroscopy (FTIR), X-ray Diffraction (XRD) and Scanning Electron Microscope (SEM). From the results it was found that intercalation or nearly exfoliation has been occurred between the polymer and the clay. Electrical conductivity was also …

Green Synthesis of Gold Nanoparticles Using Piper Nigrum (Black Pepper) Aqueous ExtractBy Sumit S. Lal, P.L. Nayak
Abstract: In the present study, we wish to report the green synthesis of gold nanoparticles using aqueous extract from fruit of black pepper. The extract with different concentrations was reduced with HAuCl4 aqueous solution at room temperature. The color change, pH change and UV-visible spectroscopic analysis reveal the surface plasmon resonance (SPR) of the final reaction product which confirms the reduction of Au3+ ion to gold nanoparticles. The FTIR spectra confirms …
