Structural and Electrical Properties of Sintered Barium-Zinc-Titanate Ceramics
(Warsaw : Institute of Physics, Polish Academy of Science, 2011)
The aim of this work was an investigation of structural and electrical properties of sintered barium-zinc-titanate ceramics. Mixtures of BaCO3, ZnO and TiO2 were mechanically activated in a planetary ball mill up to 80 ...
Nanosized hydroxyapatite and other calcium phosphates: Chemistry of formation and application as drug and gene delivery agents
(Hoboken, NJ : John Wiley & Sons, 2011)
The first part of this review looks at the fundamental properties of hydroxyapatite (HAP), the basic mineral constituent of mammalian hard tissues, including the physicochemical features that govern its formation by ...
Effect of poly-α, γ, L-glutamic acid as a capping agent on morphology and oxidative stress-dependent toxicity of silver nanoparticles
(Dove Medical Press, 2011)
Highly stable dispersions of nanosized silver particles were synthesized using a straightforward, cost-effective, and ecofriendly method. Nontoxic glucose was utilized as a reducing agent and poly- α, γ, L-glutamic acid ...
Dense fine-grained biphasic calcium phosphate (BCP) bioceramics designed by two-step sintering
(Elsevier, 2011)
In this study, dense, fine-grained biphasic calcium phosphate bioceramics were designed via the two-step sintering method. The starting powder was nanosized calcium-deficient hydroxyapatite, whose phase composition, average ...
Temperature dependence of In1−xGaxSb reflectivity in the far infrared
(Materials Chemistry and Physics, 2011)
Far infrared reflectivity spectra of polycrystalline In1−xGaxSb were measured and numerically analyzed using the classical dispersion formula and also a fitting procedure based on the modified plasmon-phonon interaction ...
Sintering process influence on microstructure and intergranular impedance of rare-earth modified BaTiO3-ceramics
(Belgrade : International Institute for the Science of Sintering, 2011)
Sintering process is a complex of different synergetic effects during the ceramics materials consolidation. The microstructural level properties control is very important as a stage in advanced materials prognosis. SEM ...

Nax−y Hy Ti2−x Fex O4 ·nH2 O nanosheets with lepidocrocite-like layered structure synthesized by hydrothermal treatment of ilmenite sand
(Springer, 2011)
Nax−yHyTi2−xFexO4·nH2O nanosheets with lepidocrocite-like layered structure were produced through alkaline hydrothermal treatment at very low temperatures (130°C) from ilmenite sand. The crystal structure, morphology and ...
Interdependence of fundamental and applied research in material science
(Belgrade : International Institute for the Science of Sintering, 2011)
Development of materials with desirable properties essentially depends on realization of interdependence: natural science ⇔ technical sciences. Taking this into account, in order to develop of new advanced materials it is ...
