Efficient Synthesis of Amides Over Cu-Fe Decorated Multiwalled Carbon Nanotubes and Mesoporous Carbon Catalysts.

A mixture of Cu (10%) and Fe (1 to 9%) was deposited on multiwalled carbon nanotubes (MWCNTs) and mesoporous carbon (MC). The catalytic activity was investigated in a reaction between carboxylic acids/esters and aromatic amines. The physico-chemical properties of the materials were characterized by different analytical techniques such as powder XRD (X-ray diffraction), BET (brunauer emmett teller) surface area, XPS (X-ray photoelectron spectroscopy), TPD-NH₃ (thermal desorption spectroscopy), SEM-EDS (scanning electron microscopy-energy dispersive spectroscopy) and TEM (transmission electron microscopy).

Synthesis of Acetamide Derivatives using S-MWCNT and S-MC as an Efficient Heterogeneous Catalysts.

Sulphate modified multiwalled carbon nanotubes (S-MWCNT) and Mesoporous carbon (S-MC) catalysts were prepared by wet impregnation method. These materials were characterized by different analytical techniques such as Powder-XRD, BET surface area analysis, SEM-EDS and TEM analysis to evaluate their bulk and surface properties. Surface acidity of the catalyst was measured by TPD-NH3 technique, as well as n-butyl amine titration.

Design of Sulphate Modified Solid Acid Catalysts for Transesterification of Diethyl Malonate with Benzyl Alcohol.

Sulphate ion modified multiwalled carbon nanotubes (S-CNTs), mesoporous carbon (S-MC), zirconia (S-ZrO2), alumina (S-Al2O3) and silica (S-SiO2) were prepared by wet impregnation technique. The physico-chemical properties of the prepared materials were investigated by Powder-XRD, BET-Surface area and SEM-EDS analysis. Surface acidity of the materials was analyzed using TPD-NH3 and n-butyl amine titration methods.

Elucidation of cell killing mechanism by comparative analysis of photoreactions on different types of bacteria.

The mechanism of biocidal action of nano titania on Escherichia coli and Staphylococcus aureus has been evaluated by various biochemical techniques like lipid peroxidation, hydrolysis of orthonitrophenol β-D-galactopyranoside, estimation of protein-amino acid and bacterial nucleic acids leakage into solution, in addition to morphology studies by electron microscopy (TEM and SEM) and K(+) ion leakage by inductively coupled plasma optical emission spectrometry. The active anatase phase of nano titania has been synthesized by sol-gel and pulverization techniques to obtain particle sizes averaging around 11 nm. The nano semiconductor with a bandgap of 3.
