Effect of LiYO(2) addition on sintering behavior and indentation properties of silicon nitride ceramics
(International Journal of Materials Research, 2006)
The influence of the sintering additive LiYO(2) (5-15 wt.%) on sintering behavior, microstructure and mechanical properties of Si(3)N(4) ceramics was investigated. Since LiYO(2) enables densification of Si(3)N(4) at ...
Synthesis, structural and luminescent properties of Gd2O3-SiO2 : Eu3+ nanopowder composites
(Materials Science Forum, 2006)
In view of the improvement of luminescent intensity in classical phosphors, different new techniques of synthesis have been developed. One of them is the sol-gel technique for nanopowder synthesis. Applied to a binary ...
Biphonons in the beta-Fermi-Pasta-Ulam model
(Physica. D: Nonlinear Phenomena, 2006)
Discrete breathers or intrinsic localized modes are nonlinear localized states that appear in several classical extended systems, such as for instance the Fermi-Paste-Ulam (FPU) model. In order to probe the quantum states ...
XRD analysis of calcium phosphate and biocomposite calcium phosphate/bioresorbable polymer
(Materials Science Forum, 2006)
Composite biomaterials based on calcium phosphate ceramic due to their high bioactivity are of interest for biological application and bone tissue repair. Structural and microstructural parameters of inorganic constituent ...
Haemodynamic and clinical effects of ularitide in decompensated heart failure
(European Heart Journal, 2006)
Aims Ularitide is a synthetic form of urodilatin, a natriuretic peptide produced in the kidney with vasodilating, natriuretic, and diuretic effects, that offers promise for the management of decompensated heart failure ...
Luminescence and structural properties of Gd2SiO5 : Eu3+ nanophosphors synthesized from the hydrothermal obtained silica sol
(Journal of Alloys and Compounds, 2006)
In this paper is given a synthesis of Gd2SiO5 (GSO) host lattice doped with Eu3+ ions using silica sol obtained by hydrothermal method as a main precursor for its nanostructure designing. X-ray diffraction, dynamic light ...
Magnetic properties of nanostructured SiO2: Eu3+ powders
(Journal of the Serbian Chemical Society, 2006)
Eu-doped silica nanoparticles with different concentrations of europium (3 %, 6 % and 15 at. %) were prepared by a hydrothermal procedure. Light scattering measurements of the silica colloids as well as TEM microscopy, ...

Sintering of Si3N4 with Li-exchanged zeolite additive
(International Journal of Materials Research, 2006)
This paper deals with the densification and phase transformation of Si3N4 with additives of Li-exchanged zeolite during pressureless sintering at significantly reduced temperatures. Dilatometric shrinkage data show that ...
A method of vehicle active suspension design
(Forschung Im Ingenieurwesen = Engineering Research, 2006)
This paper contributes to the design of active suspension systems, by the use of spatial vehicle model, without filtered feedback of the control system. A method of stochastic parameters optimisation has been utilized for ...
