Conditioning of the filament for diamond deposition by hot-filament chemical vapour deposition method
(Journal of the Serbian Chemical Society, 1998)
A tungsten filament, 0.12 mm in diameter, was conditioned by heating in a mixture of methane and hydrogen of three different concentration ratios. The filament was heated by an electric current. The procedure was carried ...
Self-organization in a dissipative three-wave interaction
(Physical Review E, 1999)
A nonlinear three-wave interaction in an open dissipative plasma model of a stimulated Raman backscattering is studied. An anomalous kinetic dissipation due to electron trapping and plasma wave breaking is accounted for ...
Influence of sodium dodecyl sulfate micelles on the kinetics of complex formation between Pd(H2O)(4)(2+) and glutathione
(Polyhedron, 1997)
The kinetics of the complex formation between Pd(H2O)(4)(2+) and glutathione was investigated in the presence of sodium dodecyl sulfate in the acidity range from 2 M HClO4 to pH 5. Acceleration (from 2 M HClO4 to pH 3.5) ...
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 ...
Codominant regulation of keratin gene expression by cell surface receptors and nuclear receptors
(Experimental Cell Research, 1996)
Epidermal keratinocytes are subject to a large variety of signals that modulate their differentiation in health and their activation in disease. Hormones and vitamins, which act via nuclear receptors, affect the differentiation ...
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 ...
