Reaction sintering of the 2ZnO-TiO2 system
(Belgrade : International Institute for the Science of Sintering, 2007)
Sintering kinetics of the mechanically activated ZnO-TiO2 system was studied. Mixtures of ZnO and TiO2 powders were mechanically activated using a high-energy ball mill for different time intervals from 0 to 300 minutes. ...
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 ...
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. ...
Uloga sintetičkih biomaterijala u procesu regeneracije resorbovane alveolarne kosti / The role of synthetic biomaterials in resorptive alveolar bone regeneration
(Belgrade : Association of the Chemical Engineers of Serbia, 2007)
Gubitak koštanog tkiva, usled resorpcije viličnih kostiju, ima značajno mesto u stomatologiji. U cilju rešavanja problema deficita koštanog tkiva nastalih resorpcijom alveolarne kosti pristupilo se primeni sintetičkih ...
Influence of mechanical activation on synthesis and properties of the MgO-TiO2 system
(Belgrade : International Institute for the Science of Sintering, 2007)
Materials applied in electronics such as multilayer capacitors are an important field of ceramic materials. Magnesium titanate based dielectric materials are used for producing type-I capacitors. A common way of obtaining ...
Morphological features of Y203:Eu particles obtained through twin fluid and ultrasonic atomization
(Novi Sad : Faculty of Technology, 2007)
Modem display devices such as plasma display and field emission display employ advanced Eu-doped yttrium oxide material, a well-known red phosphor. Utilization in such devices requires particles with spherical shape, narrow ...
Aerosol sinteza nanostrukturnih čestica Y2O3:Eu3+
(Beograd : Društvo za istraživanje materijalaBeograd : Institut tehničkih nauka SANU, 2007)
Primena Y2O3:Eu3+ u savremenim displej uređajima uslovljena je posedovanjem tačno određenih strukturnih i morfoloških karakteristika prahova koje se mogu obezbediti primenom aerosol sinteze. U ovom radu Y1.9Eu0.1O3 i ...
