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 ...
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 ...
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.%, ...
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 ...
Ectopic osteogenesis and hematopoiesis after implantantion of bone marrow cells seeded on HAP/PLLA scaffold / Ektopična osteogeneza i hematopoeza iz implantiranih ćelija koštane srži na matrici od biokompozita HAP/PLLA
(Belgrade : Association of the Chemical Engineers of Serbia, 2009)
Bone tissue reconstruction and reparation is a big challenge in medicine. Biocomposite materials based on hidroxyapatite are widely used in reparation of bone defects. Adult bone marrow-derived stem cells may be considered ...
Correlation between isothermal expansion and functional properties change of the Fe81B13Si4C2 amorphous alloy
(Belgrade : International Institute for the Science of Sintering, 2009)
The structural changes effect on functional properties of ribbon shaped samples of the Fe81B13Si4C2 amorphous alloy during annealing process was investigated in this paper. Differential scanning calorimetry method has shown ...
Hydrothermal synthesis of nanosized pure and cobalt-exchanged hydroxyapatite
(Philadelphia : Taylor & Francis, 2009)
Pure and cobalt-exchanged hydroxyapatite (HAp and CoHAp) powders were synthesized by hydrothermal method. X-ray diffraction (XRD), Raman spectroscopy, particle size analysis, inductively coupled plasma (ICP) emission ...
Controllable synthesis of horseradish peroxidase loaded poly(D,L-lactide) nanospheres
(American Scientific Publishers, 2009)
In this work, horseradish peroxidase (HRP), a model protein, was encapsulated by the precipitation method with additional step of homogenization, using polymer poly(D,L-lactide) (PDLLA). The purpose of this study was to ...
