FT-IR spectroscopic study of the Hofmann-T-d-type clathrates: Ni(1,9-diaminononane)M'(CN)(4).2G (M' = Cd or Hg, G = benzene, 1,2-dichlorobenzene or 1,4-dichlorobenzene)
(Croatian Chemical Soc, 2007)
New Hofmann T-d-type clathrates in the form of Ni(1,9-diaminononane)M'(CN)(4) center dot 2G (M' = Cd or Hg, G = benzene, 1,2-dichlorobenzene or 1,4-dichlorobenzene) were prepared in powder form and their infrared spectra ...
Influence of the thickness on physical properties of chemical bath deposited hexagonal ZnS thin films
(2007)
Hexagonal ZnS thin films of thicknesses ranging between 454 to 750 nm are deposited on a glass substrate by chemical bath deposition at 80 °C. The ZnS thin films are characterized by X-ray diffraction (XRD) and optical ...
Synthesis, spectral studies of salicylidine-pyridines: Crystal and molecular structure of 2-[(1E)-2-aza-2-(5-methyl (2-pyridyl)ethenyl)]-4-bromobenzen-1-ol
(Pergamon-Elsevier Science LTD, 2007)
Schiff bases derived from different meta-substituted salicylaldehyde and 5-methylaminopyridine have been synthesized and characterized by elemental analysis, FT-IR, NMR and UV-vis techniques. NMR assignments were made using ...
Cr(III)-imprinted polymeric beads: Sorption and preconcentration studies
(Elsevier Science BV, 2007)
The purpose of this study is to prepare a novel molecular imprinted adsorbent to Cr(III) analysis with high selectivity. Initially, chromium (III)-methacryloylhistidine (MAH/Cr(III)) complex monomer was synthesized and ...
N-acylbenzotriazole mediated synthesis of some methacrylamido amino acids
(Bentham Science Publ LTD, 2007)
N-acylbenzotriazole mediated synthetic methodology for introducing methacryloyl ( MA) group onto amino acids with complete retention of chirality has been disclosed.
Variation of photoluminescence from Si nanostructures in SiO2 matrix with Si+ post implantation
(2007)
Si nanoclusters were formed by 28Si ion implantation into SiO2 matrix and subsequently annealed at 1050 °C for 2 h under N2 ambient. The photoluminescence (PL) characteristics depend on the 28Si fluence. The PL signals ...
H-1 C-13 NMR and (n)J(CH) coupling constants investigation of 4-Phenylpyridine: A combined experimental and theoretical study
(Elsevier Science BV, 2007)
Proton coupled and uncoupled C-13, H-1, DEPT, COSY and HETCOR NMR spectra of 4-Phenylpyridine (4-Phpy) have been reported for the first time except for its H-1 NMR spectrum. In order to provide a precise structural elucidation ...
Adsorption potential of lead(II) ions from aqueous solutions onto Capsicum annuum seeds
(Taylor & Francis Inc, 2007)
The purpose of this work was to evaluate the adsorption potential of Capsicum annumn seeds, in a batch system for the removal of lead(H) ions from aqueous solutions. The experimental results showed that this agricultural ...
Effects of In, Al and Sn dopants on the structural and optical properties of ZnO thin films
(Pergamon-Elsevier Science LTD, 2007)
Effect of In, Al and Sn dopants on the optical and structural properties of ZnO thin films have been investigated by X-ray diffraction technique and optical characterization method. X-ray diffraction patterns confirm that ...
Oxidation of 2,6-di-tert-butylphenol with tert-butyl hydroperoxide catalyzed by iron phthalocyanine tetrasulfonate in a methanol-water mixture
(Elsevier Science BV, 2007)
The oxidation of 2,6-di-tert-butylphenol (DTBP) with tert-butyl hydroperoxide (Bu'OOH) catalyzed by iron phthalocyanine tetrasulfonate ([FePcTS]) in a 8-to-1 methanol-water mixture resulted with about 70-80% conversion of ...
