THE well-known test for liver oils, which consists in the production of a blue or purple coloration on agitating a solution of the oil in carbon disulphide or chloroform with a drop of concentrated sulphuric acid has generally been attributed to the presence in such oils of cholesterol and lipochromes. Recently, however, Drummond and Watson [1922] have drawn attention to the parallelism occurri...

Two new chelating resins (o-HAP-DDE-HCHO and o-HAP-DDE-FFD), having multiple functional groups are synthesised by condensing the Schiff base of o-hydroxyacetophenone-4,4'-diaminodiphenylether (o-HAP-DDE) with formaldehyde and furfuraldehyde, respectively. The extent of loading of metal ions Cu(II) and Ni(II) was studied in both competitive and non-competitive conditions varying the time of cont...

The aim of this work was to evaluate the anti-Candida efficacy of twenty five molecules of plant origin. Based on their MICs, effective molecules were categorized into four categories. Susceptibility testing of test compounds was carried out by standard methodology (M27-A2) as per CLSI guidelines. Minimum Fungicidal Concentration (MFC) was determined as the lowest concentration of drug killing ...

The schiff base ligand was prepared from furfuraldehyde with 4-amino-5-mercapto-5triazole and characterised. The metal complexes of Ti(III),V(III),Mn(III),Co(III) and Ru(III) derived from this ligand were characterised by elemental analyses, molar conductance,magnetic measurements, infra red 1H NMR & electronic spectral data. Based on these studies octahedral structures have been assigned to th...

This work describes a molecular-level investigation of strong metal-support interactions (SMSI) in Pt/TiO(2) catalysts using sum frequency generation (SFG) vibrational spectroscopy. This is the first time that SFG has been used to probe the highly selective oxide-metal interface during catalytic reaction, and the results demonstrate that charge transfer from TiO(2) on a Pt/TiO(2) catalyst contr...

in the present study, the effects of calcium doping on the performance of the co-precipitated cu-mgo catalysts prepared with different calcium loadings in the selective hydrogenation of furfuraldehyde were investigated. the results proved that the addition of this promoter had a remarkable impact on the catalytic performance. the conversion of furfuraldehyde enhanced up to 83% and the furfuryl ...

In the present study, the effects of calcium doping on the performance of the co-precipitated Cu-MgO catalysts prepared with different calcium loadings in the selective hydrogenation of furfuraldehyde were investigated. The results proved that the addition of this promoter had a remarkable impact on the catalytic performance. The conversion of furfuraldehyde enhanced up to 83% and the furfuryl ...
