Pairing in planar organic superconductors
(Elsevier, Amsterdam, 2005)
The nature of superconductivity in planar organics is still a controversial problem. We investigate two types of d-wave and extended s-wave pairing proposed theoretically in a model of kappa-(BEDT-TTF)(2)X organic ...
Superfluid density and pairing in planar organic superconductors
(Elsevier, Amsterdam, 2005)
We calculate self-consistently in-plane superfluid density rho(parallel to)(s) in planar organic superconductors to]for three types of pairing symmetry: d(x2-y2), d(xy)-like and extended s-wave pairing. Assuming strong ...
The ionic equilibrium in the CuSO4-H2SO4-H2O system and the formation of the honeycomb-like structure during copper electrodeposition
(Srpsko hemijsko društvo, Beograd, 2008)
The ionic equilibrium of the species in the CuSO4-H2SO4-H2O system was employed to systematize the conditions of copper electrodeposition leading to the formation of the honeycomb-like structure. The reason why CuSO4 ...
Electrodeposition and characterization of Fe-Mo alloys as cathodes for hydrogen evolution in the process of chlorate production
(Srpsko hemijsko društvo, Beograd, 2005)
Fe-Mo alloys were electrodeposited from a pyrophosphate bath using a single diode rectified AC current. Their composition and morphology were investigated by SEM, optical microscopy and EDS, in order to determine the ...
Mechanochemical synthesis of CaTiO3 from CaCO3-TiO2 mixture
(Trans Tech Publications Ltd, 2004)
The synthesis of calcium titanate, CaTiO3, was performed by mechanical activation and thermal treatment. Milling for up to 360 minutes in a planetary ball mill mechanically activated an equimolar mixture of CaCO3 and TiO2 ...
A phenomenological analysis of sintering kinetics of alumina
(Trans Tech Publications Ltd, Durnten-Zurich, 2004)
In this paper a phenomenological analysis of the sintering kinetics of alumina powder compacts with different proportions of small and large particles has been made. A phenomenological approach enables definition of ...
Microstructural properties of PZT thin films deposited on LaNiO3-coated substrates
(Trans Tech Publications Ltd, Durnten-Zurich, 2007)
The modified polymeric precursor method (Pechini method) was successfully used for the preparation of epitaxial and polycrystalline ferroelectric Pb(Zr0.52Ti0.48)O-3 (PZT) thin films. Films were deposited on LaNiO3 (LNO) ...
The influence of tribophysical activation on non-isothermal sintering of BaTiO3 ceramics
(Trans Tech Publications Ltd, Durnten-Zurich, 2006)
In this paper the influence of tribophysical activation on non-isothermal sintering of barium titanate has been investigated. BaTiO3 Powders were tribophysically activated in a planetary ball mill for 0, 60 and 120 min., ...
Microstructural properties of PZT thin films deposited on LaNIQ 3-coated substrates
(Trans Tech Publications Ltd, 2007)
The modified polymeric precursor method (Pechini method) was successfully used for the preparation of epitaxial and polycrystalline ferroelectric Pb(Zr0.52Ti0.48)O3 (PZT) thin films. Films were deposited on LaNiO3 (LNO) - ...
Correlation between densification rate and microstructure evolution of mechanically activated BaTiO3
(Taylor & Francis Ltd, Abingdon, 2005)
Increasing demands on the quality of electronic ceramics requires a well-controlled correlation between particle morphology and processing conditions. Since mechanical activation is one of the methods for modification of ...
