Strukturne, morfološke i funkcionalne karakteristike nanostrukturnih oksida retkih zemalja dobijenih aerosol sintezom
(Belgrade : University of Belgrade, Faculty of Technollogy and Metallurgy, 2009)
Dobijanje ultrafinih, sferičnih, fosforescentnih čestica sa homogenom raspodelom komponenata i faza je od posebnog značaja za materijale sa primenom u savremenim optoelektronskim uređajima. Reakcija u disperznom sistemu ...
Electrical properties of mechanochemicaly activated cordierite ceramics
Three-component oxide mixture was prepared containing MgO+Al2O3+SiO2 in a 2:2:5 ratio with addition of 10% Bi203. Mixtures were mechanically activated in range from 5 to 240 minutes in a mill with ceramic balls, and sintered ...
Karakterizacija katodnih materijala LiMn2-xMxO4 (M=Mn, Cr, Zn) sintetisanih ultrazvučnom sprej pirolizom
(Belgrade : University of Belgrade, Faculty of Physical Chemistry, 2004)
Metodom ultrazvučne sprej pirolize sintetisani su prahovi LiMn2O4, LiCr0.175Mn1.825O4 i LiZn0,082Mn1,918O4. Prahovi su dobijeni raspršivanjem vodenog rastvora nitrata odgovarajućih metala, ultrazvučnim raspšivačem frekvencije ...
Water-soluble Vitamins Loaded in Biodegradable Nanoparticles
Poster presented at the 35th Annual Meeting & Exposition of the Controlled Release Society, New York, July 12-16, 2008
ZnO varistors prepared by direct mixing of constituent phases
(Sendai : Japan Institute of Metals, 2000)
ZnO varistors with non-linearity coefficients reaching 50 and low values of the leakage current (approximately 0.01 A/m2), were obtained by a method referred to as `direct mixing of constituent phases'. The method is based ...
Uticaj aditiva na sinterovanje sistema ZnO-TiO2 saglasno trijadi sinteza-struktura-svojstva
(Belgrade : University of Belgrade, Faculty of Physical Chemistry, 2007)
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 ...

The First Conference on materials science and engineering, including physics, physical chemistry, condensed matter chemistry, and technology in general, was held in September 1995, in Herceg Novi. An initiative to establish ...
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 ...
Effect of chemisorbed carbon monoxide on Pt/C electrode on the mechanism of the hydrogen oxidation reaction
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 ...
Formation of magnesium titanates
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 ...
