Far infrared properties of sintered NiO
(Elsevier, 2007)
Far infrared reflection spectra of NiO polycrystals sintered at 1100 °C for various times (30–240 min) were measured at room temperature using a FTIR Spectrometer—Brucker 113V. The measured spectra depended on the sintering ...
Far infrared reflectance of sintered nickel manganite samples for negative temperature coefficient thermistors
(Pergamon-Elsevier Science Ltd, Oxford, 2007)
Single phase complex spinel (Mn, Ni, Co, Fe)(3)O-4 samples were sintered at 1050, 1200 and 1300 degrees C for 30 min and at 1200 degrees C for 120 min. Morphological changes of the obtained samples with the siDtering ...
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 ...
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 ...
Calcium Phosphate Ceramics Calcium Phosphate Ceramics - Bioresorbable Polymer Composite Biomaterials : from synthesis to applications : (1999-2007)
(Belgrade : Institute of Technical Science of SASA, 2007)
In the past several years, the accent of a number of scientific researches in the countries of the European Union, USA and Japan was focused on the field of biomaterials. Having the direct influence on the quality and ...
Radiation-induced degradation of hydroxyapatite/poly L-lactide composite biomaterial
(Radiation Physics and Chemistry, 2007)
The effects of gamma irradiation on the structure and properties of hydroxyapatite/poly L-lactide (HAp/PLLA) biomaterial have been investigated. Effects of radiation on microstructure, degradation of polymer part and thermal ...
Obtaining nano calcium phosphate/poly(dl-lactide-coglycolide) composite biomaterial by sonochemical deagglomeration
(Belgrade : Institute of Technical Sciences of SASA, 2007)
Nanoparticles have several advantages over the microparticles in interactions of the
biomaterial with the organism. The response of the organism depends on the interaction of the
biomaterial with the surrounding tissue ...
PDLLA microparticles containing BSA: effect of formulation variables on size distribution
(Belgrade : Institute of Technical Sciences of SASA, 2007)
Worldwide, there is u currently considerable care for the development of
biodegradable microspheres as systems for controlled release of medicaments. The major
disadvantage of traditional administration routes of medicaments ...
Approximation of material behaviour of PLLA polymer in HAp/PLLA biocomposite material using nanoindentation and finite element method
(Savez inženjera metalurgije Srbije, Beograd, 2007)
In this work, a combination of nanoindentation experiment and finite element modeling is proposed in order to obtain approximate material behavior of PLLA polymer in hydroxyapatite (HAp)/poly-L-lactide (PLLA) composite. ...
