Far infrared properties of PbTe doped with cerium
(Lausanne : Elsevier Science, 2007)
Single crystal samples of lead telluride doped with cerium were made using the Bridgman method. Far infrared reflectivity spectra in the temperature range from 10 to 300K are presented. The experimental data were numerically ...
Specificity of the UPD of H to the structure of highly dispersed Pt on carbon support
(Pergamon-Elsevier Science Ltd, Oxford, 2007)
Home-made carbon cryogel synthesized by sol-gel polycondensation and freeze-drying is used as support for preparation of highly dispersed Pt catalyst that is made by a modified polyol synthesis method in an ethylene glycol ...
Nanostructured Y2O3 Particles Doped with Europium Synthesized by Aerosol Route
(Iasi : Professional Association in Modern Manufacturing Technologies, ModTech, 2009)
Y2O3 doped with europium is a well known red phosphor material employed in modern high-resolution display devices such as plasma display panels (PDP) and field emission displays (FED). The incorporation of gadolinium in ...
Oxidation of metallic binder powder and its influence on mechanical properties metal-diamond composite
(Sendai : Japan Institute of Metals, 2000)
In this paper, the properties of metallic binders based on Co, Fe, bronze and their influence on mechanical characteristics of metallic binder-diamond composites, obtained by hot pressing of these powders, were analyzed. ...
Far infrared properties of iron doped single crystal PbTe
(Măgurele : National Institute of Research and Development for Optoelectronics, 2008)
Far infrared reflectivity spectra of single crystal PbTe samples doped with 0.2 at% Fe were measured in the temperature range between 10 K and 300 K. These spectra show very sharp and narrow dips below 120 cm-1. The ...
Densification, Microstructure, and Electrical Properties of BaTiO3 (BT) Ceramics Prepared from Ultrasonically De-Agglomerated BT Powders
(Taylor & Francis, 2009)
In this study, a correlation between densification, microstructure, and electrical properties of BaTiO3 (BT) ceramics prepared from ultrasonically de-agglomerated BT powders has been analyzed. BT powders with the same ...
Corrosion behavior of magnesium, aluminum and zinc as anodic materials in chloride based electrolytes for use in primary and secondary electrochemical power sources
(Oxford : Elsevier Sci Ltd, 2009)
Corrosion behavior of magnesium, aluminum and zinc in 0.2 mol dm(-3) NH4Cl; 0.1 mol dm(-3) NH4Cl with addition of 0.1 mol dm(-3) Na-citrate and corrosion behavior of zinc in 0.3 mol dm-3 NH4Cl with addition of 0.8 mol ...
Hydroxyapatite as a root canal system filling material: Cytotoxicity testing
(Durnten-Zurich : Trans Tech Publications Ltd., 2004)
Cytotoxicity testing, as a standard assay for toxicity of dental materials, is useful for initial biocompatibility evaluations. In vitro test of calcium hydroxyapatite (CHA) with established laboratory cell line showed ...
Investigation of zinc stannate synthesis using photoacoustic spectroscopy
(Belgrade : International Institute for the Science of Sintering, 2007)
Mixtures of ZnO and SnO2 powders, with molar ratio of 2:1, were mechanically activated for 40, 80 and 160 minutes in a planetary ball mill. The resulting powders were compacted into pellets and non-isothermally sintered ...
Nanomaterial N-CP/DLPLG as potentional tissue graft in osteoreparation in combination with bone marrow cells on subcutaneous implantation model
(Belgrade : Association of the Chemical Engineers of Serbia, 2008)
The need for bone graft materials in osteoreparation is tremendous. Many researches have shown that calcium-phosphate bioceramics have good biocompatibility and osteoconductivity. We used nanocomposite biomaterial calcium ...
