Mehanohemijski tretman neorganskih materijala
(Belgrade: Association of the Chemical Engineers of Serbia, 2001)
Pod mehanohemijskim tretmanom podrazumeva se mlevenje jednog ili smeše prahova u različitim tipovima mlinova. U radu je dat kratak pregled osnovnih aspekata ovakvog tretmana i to: (a) najčeše korišćenih mlinova – atricionog, ...
Thermal diffusivity of sintered 12CaO-7Al2O3
(Belgrade : International Institute for the Science of Sintering, 2003)
The thermal diffusivity and some electrical transport properties of sintered 12CaO-7Al2O3 were determined using a photoacoustic method with a transmission detection configuration. The thermal diffusivity, coefficient of ...
Mechanochemical Treatment of Inorganic Solids: Solid–Solid Fine Dispersions
(Boca Raton, Fl : CRC Press, Taylor and Francis Group, 2005)
Milling is an important step in the processing of metallic and ceramic powders. Its primary usage has been for article size reduction/growth and change of particle shape as well as for homogenization of mixture of two or ...
Preparation of smallest microparticles of poly-D,L-lactide by modified precipitation method: Influence of the process parameters
(Hoboken, NJ : John Wiley & Sons, 2008)
Biodegradable microspheres such as those made of poly-D,L-lactide (PDLLA) are widely investigated delivery systems for drugs or antigens. The aim of this study was to examine experimental conditions in order to produce ...
Catalytic combustion of methane over Pd containing perovskite type oxides
(Elsevier Science Bv, Amsterdam, 2005)
The mixed perovskite type oxides with nominal formula LaTi0.5Mg0.5-xPdxO3, (0 LT = x LT = 0.10) were prepared by anneling the ethanol solution of precursor in nitrogen flow at 1200 degrees C. X-ray powder diffraction ...
Primena Ramanove spektroskopije u proučavanju mehaničke aktivacije BaTiO3
(Beograd : Institut tehničkih nauka SANU, 2006)
U ovom radu su ispitivane strukturne promene BaTiO3 tokom mehaničke aktivacije. Kao početni prah, korišćen je BaTiO3 (Aldrich) prah čistoće 99.9%. Mehanička aktivacija ovog praha izvršena je mlevenjem u visokoenergetskom ...

Evolution of the microstructure of disperse ZnO powders obtained by the freeze-drying method
(Lausanne : Elsevier Science, 2004)
Freeze-drying, as a cryochemical powder processing method is applied in the synthesis of ZnO submicrometer to narrosized powders. The process involves rapid freezing of the sprayed precursor solution, drying under vacuum ...
A kinetic study of D-glucose oxidation by bromine in aqueous solutions
(Oxford : Elsevier Sci Ltd., 2006)
The kinetics of the oxidation Of D-glucose to D-gluconic acid by bromine in aqueous solution were studied using potentiometric techniques and theoretical considerations of complex bromine-bromide-pH equilibria. The pH has ...
