Influence of solvent on the structural and morphological properties of AgI particles prepared using ultrasonic spray pyrolysis
(Materials Chemistry and Physics, 2008)
Silver iodide particles were synthesized in the process of ultrasonic spray pyrolysis using aqueous solutions of thermodynamically stable silver iodide clusters as precursor. The AgI particles were collected in solvents ...
Ground-state magnetism of chromium-substituted LiMn2O4 spinel
(Journal of Magnetism and Magnetic Materials, 2008)
Comparative crystal structure and magnetic properties studies have been conducted on quaternary powder spinel samples LiMn1.82Cr0.18O4 obtained by two different synthesis methods, glycine-nitrate (GN) and ultrasonic ...
Intrinsic resistivity of sintered Nickel Manganite vs. powder activation time and density
(Belgrade : International Institute for the Science of Sintering, 2008)
In this work the DC resistivity of sintered nickel manganite NiMn2O4 (NTC thermistor material) was studied as a function of additional powder activation time in a planetary ball mill (0, 5, 15, 30, 45 and 60 min). The ...
Synthesis of BaTiO3 from a mechanically activated BaCO 3-TiO2 system
(Belgrade : International Institute for the Science of Sintering, 2008)
In this article the solid state reaction of BaTiO3 formation from a mechanically activated BaCO3-TiO2 system has been investigated. An equimolar mixture of BaCO3 and TiO2 powders was activated in a planetary ball mill in ...
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 ...
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 ...
Far infrared properties of PbTe doped with Bismuth
(Springer Science+Business Media, 2008)
Far infrared reflectivity spectra of single crystal PbTe doped with Bi were measured and numerically analyzed using a fitting procedure based on a modified plasmon-phonon interaction model with two additional oscillators ...
Preparation of smallest microparticles of poly-D,L-lactide by modified precipitation method: Influence of the process parameters
(Hoboken, NJ : John Wiley & Sons, 2008)
Biodegradable microspheres such as those made of poly-D,L-lactide (PDLLA) are widely investigated delivery systems for drugs or antigens. The aim of this study was to examine experimental conditions in order to produce ...
Morphological changes of poly(DI-lactide-co-glycolide) nano-particles containing ascorbic acid during in vitro degradation process
(Wiley, 2008)
Poly(dl-lactide-co-glycolide) powder composed of uniform particles with the mean particle size in the range of 110-170 nm was obtained from commercial granules. Ascorbic acid in different concentrations was encapsulated ...
