the in-situ method of synthesis has been used to isolate oxovanadium(iv) complexes with ligands derived by reaction of benzil with amino acids such as glycine, alanine, serine, cysteine and valine, where template effect of vo +2 cation appears to play an important role. the complexes are characterised by elemental analysis, magnetic moment measurements and spectral (infrared, electronic and ele...

in comparison to the previous researches, zro2 nanoparticles with higher surface area (85 m2/g) have been synthesized in this research. the as-prepared zro2 nanoparticles by co-precipitation method were characterized with x-ray diffraction (xrd), scanning electron microscopy (sem) and transmission electron microscopy (tem). the surface area of the sample was characterized by bet method. the eff...

To investigate template effect on physicochemical properties of zeolite and enhance the molecular sieving properties, adsorption of methionine amino acid was studied by spectroscopic methods. Four zeolites such as methionine templated analcime, methionine templated zeolite P, N, N-dibenzyl N,N,N,N-tetramethylethylenediamine (DBTMED) templated analcime and free template analcime were synthesized...

the study reports some preliminary investigations on the template free synthesis of a scantly investigated polyaniline (pani) derivative-phenylenediamine (pda) by template free method in the presence of oxalic acid (oa) (dopant), using ammonium persulfate as oxidant. polymerization of phenylenediamine (pda) was confirmed by the ft-ir as well as uv–visible studies. the morphology of phenylenedia...

metal complexes, ml (m=ni, cu, co and zn) of unsymmetrical tetradentate schiff base have been synthesized by the template reaction of the half-units n-(1-hydroxy-2-acetonaphthone)-1-amino-2-phenyleneimine)(hl1) with 2-pyrroleca-rbaldehyde. the complexes have been characterized by elemental analysis, ir, 1h nmr and uv spectroscopy. the crystal structure of the ni(ii) complex has been determine...
