Sodium Benzoate and Urea as Promoters in Sillimanite Flotation
Abstract: Sillimanite is an alumino-silicate mineral with the chemical formula Al2SiO5. Sillimanite in general is concentrated by gravity separation methods followed by froth flotation. Hydrophobicity is induced to sillimanite surface by adsorbing surfactant (oleic acid/oleate) molecules selectively and the mineral is collected into froth as concentrate. Other reagents used are; sodium silicate to depress garnet and silica and sodium hydroxide to adjust the pulp pH. In the present study, hydrotropes (sodium …

Structural Investigations of NiFe2O4 Synthesised by the Pyrolysis of Single Source Precursor
Abstract: NiFe2O4 nanoparticles have been synthesized using the single source precursor [NiFe2(cin)3(N2H4)3] via pyrolysis thermal decomposition route. The single source precursor prepared by a simple precipitation method, was characterised by hydrazine and metal analyses, infrared spectral analysis and thermo-gravimetric analysis. Using appropriate annealing conditions, NiFe2O4 nanoparticles were synthesised by the thermal treatment of the precursor. From XRD and HRTEM studies, the particle size of the sample was found to be around …

Synthesis, Characterization and Applications of Poly (2-Methyl Aniline-co-2-Chloro Aniline) and Poly (2-Methyl Aniline-co-2-Chloro Aniline)-Nanocomposite-CuO
Abstract: The copolymer and its composite, poly (2-methyl aniline-co-2-chloro aniline) and poly (2-methyl aniline-co-2-chloro aniline)-nanocomposite-CuO respectively were synthesized by chemical oxidative polymerization method using ammonium persulphate as oxidant, sodium lauryl sulphate as surfactant and HCl as dopant. The synthesized copolymer and composite were characterized by FTIR, UV-Visible and 1H NMR spectroscopy. The thermal stability was determined by TGA/DTA. The copolymer and copolymer nanocomposite with CuO were found to be thermally more …

Evolution of Empirical Equations for Prediction of Melting Point and Latent Heat of Alkanes
Abstract: Alkanes and paraffins are well recognized phase change materials (PCMs) for low and medium range temperature thermal energy storage applications. Melting point and latent heat are two crucial parameters for any PCM for its use in any thermal storage application. The values of these parameters are normally measured by expensive and time consuming measuring devices.In this paper, three empirical equations are presented to predict the melting point and latent heat …
