(Elsevier Science BV, 2005)
The condensation reactions of [N-[(2-hydroxyphenylmethyl)amino]-methylpyridines (5-8) with trimer, N3P3Cl6, have been afforded partially substituted novel spiro-cyclic phosphazene derivatives (9-12) (Scheme 1). Compounds ...
Modification of bentonite with a cationic surfactant: An adsorption study of textile dye Reactive Blue 19
(Elsevier Science BV, 2007)
The utilization of modified bentonite with a cationic surfactant (dodecyltrimethylammonium (DTMA) bromide) as an adsorbent was successfully carried out to remove a synthetic textile dye (Reactive Blue 19 (RB 19)) by ...
Electrochemical oxidation of ds-DNA on polypyrrole nanofiber modified pencil graphite electrode
(Wiley-V C H Verlag GMBH, 2007)
Preparation of a polypyrrole nanofiber (PPyNF) modified pencil graphite (PG) electrode and its usage in the electrochemical DNA biosensors was investigated. The electrodes (PPyNF/PG1 and PPyNF/PG2) were prepared from a ...
The effect of the pairing interaction on the energies of isobar analogue resonances in Sb112-124 and isospin admixture in Sn100-124 isotopes
(IOP Publishing LTD, 2004)
In the present study, the effect of the pairing interaction and the isovector correlation between nucleons on the properties of the isobar analogue resonances (IAR) in Sb112-124 isotopes and the isospin admixture in Sn100-124 ...

Synthesis and spectroscopic characterization of new Schiff bases containing the benzo-15-crown-5 moiety
(Molecular Diversity Preservation International, 2004)
New crown ether Schiff base derivatives were prepared by the condensation of 4'-formylbenzo-15-crown- 5 or 4'-formyl-5'-hydroxybenzo-15-crown-5 with 1,2-bis(2aminophenoxy)ethane. The structures of these new compounds were ...
Gamow-Teller 1(+) states in Bi-208
(Amer Physical Soc, 2005)
The properties of the Gamow-Teller (GT) 1(+) states in Bi-208 have been investigated by using the Pyatov-Salamov method. The GT resonance (GTR) energy, the contribution of the GTR beta transition strength to the Ikeda sum ...
Self-consistent calculations of isospin admixtures in the ground states of the N = Z nuclei in the mass region of 50-100
(Elsevier Science BV, 2007)
In the present study, based on spherical shell-model wave functions and energies with the pairing and the residual Fermi interaction treated in pn QRPA, the isospin admixture probabilities in the ground state of N = Z ...
The determination of the thickness and optical constants of the ZnO crystalline thin film by using envelope method
(Natl Inst Optoelectronics, 2006)
ZnO crystalline thin film has been deposited onto glass substrates by the spray pyrolysis method. The crystallographic structure of the film and the size of the crystallites in the film were studied by X-ray diffraction. ...
