An innovative, quick and convenient labeling method for the investigation of pharmacological behavior and the metabolism of poly(DL-lactide-co-glycolide) nanospheres
(Bristol : IOP Science, 2009)
Nanoparticles of poly(DL-lactide-co-glycolide) (PLGA) in the size range 90-150 nm were produced using the physicochemical method with solvent/non-solvent systems. The encapsulation of the ascorbic acid in the polymer matrix ...
Hidrotermalna sinteza katodnog materijala LiFePO4 u prisustvu organske komponente
(Beograd : Institut tehničkih nauka, 2009)
Katodni materijal LiFePO4 u poslednje vreme privlači veliku pažnju zbog svojih dobrih osobina kao što su visok teorijski kapacitet, stabilnost, niska toksičnost i niska cena. Glavni nedostatak ovog materijala je njegova ...
Kalcijum/kobalt hidroksiapatit nanočestice u regeneraciji osteoporotične kosti donje vilice
(Beograd : Institut tehničkih nauka, 2009)
Osteoporoza kao bolest savremene civilizacije postaje sve aktuelnija u stomatologiji. Jedan od trendova u nalaženju rešenja je u oralnoj implantologiji kroz primenu biomaterijala sa magnetnim česticama. U ovoj studiji ...
Formation of magnesium titanates
(Springer, 2009)
The paper examines the phase formation in the mechanochemical treatment and subsequent annealing of TiO 2 and MgO mixtures. It is established that the MgTiO 3 phase forms during annealing of the above powder mixtures at ...
Structural analysis of Zn2TiO4 doped with MgO
(Springer, 2009)
The starting mixtures of ZnO, TiO2, and MgO (0, 1.25, and 2.5 wt.%) powders are mechanically activated in a high-energy planetary mill for 15 min and then sintered between 800 and 1100°C for 2 h. The influence of MgO ...
Effect of chemisorbed carbon monoxide on Pt/C electrode on the mechanism of the hydrogen oxidation reaction
(Elsevier, 2009)
The influence of poisoning of Pt catalyst by CO on the kinetics and mechanism of H2 oxidation reaction (HOR) at Pt/C electrode in 0.5 mol dm-3 HClO4, saturated with H2 containing 100 ppm CO, was examined with rotating disc ...
Isothermal sintering of mechanically activated MT ceramics
(Kiev, 2009)
The aim of this work was to analyze influence of mechanical activation on MgO-TiO2 system. Mixtures of MgO-TiO2 were mechanically activated for 0, 5, 10, 20, 40, 80 and 120 minutes in a planetary ball mill and after that ...
Optical properties of PbTe and PbSnTe doped with Cr
(Elsevier, 2009)
Single crystal samples of PbTe and PbSnTe doped with Cr were made using the Bridgman technique. Far infrared diagrams of PbTe samples doped with 0.4 at.%, 0.8 at.% and 1 at.% Cr and also of Pb0.9Sn0.1Te doped with 0.4 at.%, ...
Uticaj parametara procesiranja na tok mehanohemijske sinteze i sprečavanje pojave aglomeracije sintetisanih nanostrukturnih prahova
(Belgrade : University of belgrade, Faculty of Physical Chemistry, 2009)
Keramički nanomaterijali kao što su cink oksid (ZnO) i cirkonijum dioksid (ZrO2), poseduju veliki potencijal za primenu u najrazličitijim oblastima industrijske proizvodnje pre svega zahvaljujući nanodimenzijama čestica. ...
Mineral substances in the bone tissue and blood of patients with osteoporosis
(Novi Sad : Društvo lekara Vojvodine Srpskog lekarskog društva, 2009)
Osteoporosis is a very common disorder of skeleton, which can be caused by various metabolic disturbances, malnutrition, immobilization, endocrine disorders, bone marrow diseases, connective tissue disorders, and, in some ...
