    Abstract: A new macrocyclic Schiff base complexes were prepared in the presence of lanthanide metal ion[La(III), Ce(III) and Gd(III)] by the reaction of 2,6 – diamino pyridine, benzoyl aceton and metal ion as template effect in the molar ratio of 2: 2: 1 respectively. The lanthanide metal complexes were characterized and investigated by using; 1HNMR, FTIR,... Show More

    Abstract: A total number of 22 different spices (both natural spices and industry produced spices) bought from the Accra Markets, Ghana, were analyzed for phenolic and flavonoid content to see their impact in food preparation. The phenolic concentrations were high in the natural spices compared to the industry produced spices with the exception of IPS1 and I... Show More

    Abstract: A series of novel amino acid derived Schiff-bases and their Oxovanadium(IV) complexes were synthesized and well characterized by elemental analyses, spectral studies, conductivity and magnetic measurements. Physical and analytical data suggest that the Schiff bases act as tridentate ligands towards metal ion via azomethine-N, deprotonated-O of carb... Show More

    Abstract: The electro-electrodialysis process (EED) is used to generate H2SO4 and NaOH from sulphate sodium salt Na2SO4. The key phenomenon limiting the current efficiency of this process is the proton leakage through the anion selective membrane was not observed. The electro-electrodialysis was carried out with a three-compartment cell with two platinum-coa... Show More
