The favored trans(O-6) geometry in hexadentate copper(II) complexes of 1,3-propanediamine-N,N-diacetic-N,N-di-3-propionic acid. Crystal structure of trans(O-6)-Na-2[Cu(1,3-pddadp)]center dot NaNO3 center dot 2H(2)O. Strain analysis and spectral assignments of complexes
(Inorganica Chimica Acta, 1997)
The octahedral copper(II) complexes of 1,3-propanediamine-N,N-diacetic-N,N-di-3-propionic acid (H(4)1,3-pddadp) prepared in the region of pH 2 to 7 are hexadentates. Only one (trans(O-6)) of the three geometrical isomers ...
Surface properties of metal ions modified silicas
(Colloids and Surfaces. A: Physicochemical and Engineering Aspects, 1999)
The surface properties of metal (alkali and alkaline earth) modified silica beads were investigated by the inverse gas chromatography method. Silica beads, obtained from silica sol, were characterized by their specific ...
Fully relativistic description of extraordinary and quasilongitudinal waves propagating in plasmas
(Plasma Physics and Controlled Fusion, 1999)
Extraordinary and quasilongitudinal waves propagating at an arbitrary angle with respect to the steady magnetic field are investigated within the fully relativistic theory. The results of the present paper complement the ...
Exact solution of the Ising model on checkerboard fractals in an external magnetic field
(Physical Review E, 1998)
In this paper we use a diagrammatic technique to determine the exact recursion relations for the partition function of the Ising model in an external magnetic field, situated on the first two members of the checkerboard ...
Prefission neutron multiplicities and the fission modes of Th-226
(Europhysics Letters / EPL, 1999)
The neutron spectra associated to the two fission modes of Th-226 have been measured in coincidence with the fragment yields of the O-18 + Pb-208 reaction at E-lab = 78 MeV. The pre- and post-fission multiplicities and ...
A statistical analysis of the influence of processing conditions on the properties of fused silica
(Journal of the European Ceramic Society, 1996)
In this work the quantitative relations between the properties of sintered fused silica (density, mechanical propel-ties, cristobalite content) and slip preparation parameters as well as sintering conditions (milling balls ...
Influence of additives on the properties of spherical nickel particles prepared by ultrasonic spray pyrolysis
(Journal of Materials Research, 1999)
Ideal spherical nonagglomerated Ni particles (mean diameter 0.62-1.12 mu m) were prepared by ultrasonic spray pyrolysis of NiCl2 aqueous solution in the presence of 0.1 mass% of Pd, Cu, or Ni in an H-2-N-2 atmosphere at ...
Characterization of TiN protective coatings
(Solid State Phenomena, 1998)
This work reports on an analysis of titanium nitride layers deposited by the PVD method and changes induced in the deposit during interaction with a laser beam. Layers up to 850 nm thick were deposited by Ti target sputtering ...
Influence of the Mn2+ ion cluster formation on the EPR spectrum of Zn1-xMnxTe
(Journal of Magnetic Resonance, Series A, 1996)
The second and fourth central moments of the EPR line of the Mn2+ ion clusters are calculated for the case when isotropic and anisotropic superexchange interactions exist between paramagnetic ions. The infinite-temperature ...
