Poster presented at PHYSICAL CHEMISTRY 2008. 9th International Conference on Fundamental and Applied Aspects of Physical Chemistry, Belgrade, September 24-26, 2008
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 nanostrukturnih oksidnih prahova i njihova karakterizacija
(Belgrade : University of Belgrade, Faculty of Technollogy and Metallurgy, 2009)
Usled razvoja i primene raznih naprednih materijala u nanokristalnom obliku dolazi do potrebe za uvođenjem novih tehnologija za sintezu nanočestičnih i nanostrukturnih materijala, koje su isplative za industrijsku proizvodnju ...
High temperature sintering kinetics of a-Al2o3 powder
(Belgrade : International Institute for the Science of Sintering, 2003)
The sintering kinetics of a-Al2O3 powder is investigated in this paper Commercial a-Al2O3 powdered compacts were sintered close to 95 % of the theoretical density. The characteristic parameters of sintering kinetics were ...
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 ...
A review of recent developments in the synthesis procedures of lithium iron phosphate powders
Olivine structure LiFePO4 attracted much attention as a promising cathode material for lithium-ion batteries. The overwhelming advantage of iron-based compounds is that, in addition to being inexpensive and naturally ...
Novel uniaxial anemometer containing NTC thick film segmented thermistors
A novel uniaxial anemometer was created using a NTC thick film segmented thermistor to measure wind speed and direction. The anemometer operated on the principle of heat loss caused by the air volume flow and air speed. A ...
Influence of MgO addition on the synthesis and electrical properties of sintered zinc-titanate ceramics
Starting mixtures of ZnO, TiO2 and MgO (0, 1.25 and 2.5 wt.% MgO) powders were mechanically activated for 15 min in a planetary ball mill. The powders obtained were sintered non-isothermally to temperatures between 800 and ...
Modeling boron separation from water by activated carbon, impregnated and unimpregnated
(Roma : Società chimica italiana, 2000)
The sorption of boron from boric acid water solution by impregnated activated carbon has been studied Barium, calcium, mannitol, tartaric acid and citric acid were used as chemical active materials. All processes were ...
Injectable polydimethylsiloxane-hydroxyapatite composite cement
(Bio-Medical Materials and Engineering, 2003)
An injectable polydimethylsiloxane/hydroxyapatite (PDMS/HAp) composite cement was synthesised using linear PDMS and HAp (particles of about 100 nm in size) of different mass fractions. The effect of HAp mass fraction (5-60 ...
