Sinteza, karakterizacija i degradacija nanosfera poli(DL-laktid-ko-glikolida) koje sadrže askorbinsku kiselinu
(Belgrade : University of Belgrade, Faculty of Physical Chemistry, 2007)
Askorbinska kiselina (vitamin C) je izuzetno važan i organizmu neophodan vitamin. Ima ulogu reduktanta slobodnih radikala čime smanjuje oštećenja nastala oksidativnim stresom koji je uzrok ili pratilac mnogih bolesti. U ...
Genotoxicity of the poly-D,L-lactide microparticles on the human lymphocytes
(Belgrade : Institute of Technical Sciences of SASA, 2007)
Particles generated of biodegradable material are extensively investigated as carriers
for sustained drug delivery. Studies have been mainly focused on the monitoring of the drug
release and of the rate of the particle ...
Osteogenic activity in a mice subcutaneous implant of porous hydroxyapatite/poly-L-lactide loaded with bone marrow cells
(Belgrade : Institute of Technical Sciences of SASA, 2007)
Hydroxyapatite (HAp) is biomaterial widely used in the regeneration of bone tissue.
Addition of osteogenic cells to HAp implants may accelerate the bone repair process. The aim of
this study was to investigate how the ...
Analysis of isothermal sintering of zinc-titanate doped with MgO
(Čačak : Technical Faculty, 2007)
The aim of this work was analysis of isothermal sintering of zinc titanate ceramics doped with MgO obtained by mechanical activation. Mixtures of ZnO, Ti02 and MgO (0, 1.25 and 2.5%) were mechanically activated 15 minutes ...
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 ...
Reduction of the specific surface area of porous ZnO during sintering
(Čačak : Technical Faculty, 2007)
In this paper reduction of the specifice surface area of porous ZnO during sintering was analyzed. ZnO was sintered at temperatures from 673K to 1173K. Reduction of the specific surface area was observed as a function of ...
Photoacoustic properties of single crystal PbTe(Ni)
(Belgrade : International Institute for the Science of Sintering, 2007)
Single crystals of PbTe(Ni) were investigated by the photoacoustic method. They were produced using the Bridgeman method. These crystals have a sodium chloride cubic lattice and could be cleaved paralel to the plane ...
Procesiranje mikrosfera poli-D,L-laktid-a u koje je inkorporiran protein
(Beograd : Institut tehničkih nauka SANU, 2007)
U svetu trenutno postoji značajna potreba za otkrićem biodegradabilnih mikrosfera kao sistema za kontrolisanu dostavu medikamenata. Glavni nedostatak tradicionalnog načina doziranja medikamenata se ogleda u potrebi za ...

U okviru ove doktorske disertacije detaljno i sistematski je proučen uticaj aditiva magnezijum oksida na sintezu i sinterovanje sistema ZnO-TiO2. Smeša prahova ZnO, TiO2, MgO (0, 1,25 i 2,50 masenih % MgO), mehanički je ...
Electrodeposition of NiMo alloy coatings and their characterization as cathodes for hydrogen evolution in sodium hydroxide solution
(Belgrade : Institute of Technical Sciences of SASA, 2007)
The hydrogen evolution reaction on electrodeposited NiMo alloy coatings, as well as
their electrochemical properties in NaOH solutions have been investigated by polarization
measurements, cyclic voltammetry and EIS ...
