Uticaj gama zračenja na molekulsku masu i staklasti prelaz PLLA
(Hemijska industrija, 2010)
U ovom radu ispitivan je uticaj gama zračenja na molekulsku masu i staklasti prelaz poli-L-laktida (PLLA). S obzirom da je PLLA pri izlaganju visokoenergijskom zračenju sklon kidanju lanaca i velikoj degradaciji, promene ...
Aerosol route in processing of nanostructured phosphor materials
(Novi Sad : University of Novi Sad, Faculty of Technology, 2010)
Among the methods currently used for nanophase processing, synthesis through dispersion phase (aerosol) enables generation of ultrafine powders with controlled stoichiometry. It represents a 'bottom-up' chemical approach ...
The effect of pH of the sodium hypochlorite on smear layer removal / Uticaj pH vrednosti rastvora natrijum-hipohlorita na uklanjanje razmaznog sloja
(Srpsko lekarsko društvo - Stomatološka sekcija, Beograd, 2010)
Introduction. Canal irrigation is an important segment of endodontic treatment. The aim of this study was to assess the efficacy of 0.5% NaOCl solutions of different pH values on smear layer removal. Material and Methods. ...
Probabilistički proračun gubitka stabilnosti tankih panela pod dejstvom kombinovanog opterećenja / Probabilistic approach to buckling analysis of thin panels subject to combined loads
(Beograd : Vojnotehnički institut, 2010)
This paper gives the procedure for the reliability calculation of mechanical components and structures. The stability (buckling) of a tin panel subjected to in-plane combined (normal and shearing) loads is considered in ...
Influence of nitrogen and air atmosphere during thermal treatment on micro and nano sized powders and sintered TiO2 specimens
(Science of Sintering, 2014)
The influence of air and nitrogen atmosphere during heating on TiO2 nano and micro sized powders as well as sintered polycrystalline specimens was analyzed. Sintering of TiO2 nano and micro powders in air atmosphere was ...
Synthesis of Li2FeSiO4/C composite by sol-gel citric acid assisted method / Sinteza kompozita Li2FeSiO4/C sol-gel metodom uz pomoć limunske kiseline
(Belgrade : Union of Engineers and Technicians of Serbia, 2016)
This paper describes a procedure for the synthesis of the composite Li2FeSiO4/C by sol-gel method using citric acid as a chelating agent; the resulting gel precursor was thermally treated in a slightly reductive atmosphere ...
Isothermal sintering of barium-zinc-titanate ceramics
(Oxford : Elsevier Sci Ltd., 2011)
Mixtures of BaCO3-ZnO-TiO2 were mechanically activated using high-energy planetary ball mill during 20, 40 and 80 min. As the time of mechanical activation increased, the decrease in particle size was observed. The effect ...
Sinteza i karakterizacija LiFePo4/C katodnog materijala dobijenog pomoću postupka liofilizacije u prisustvu PVP-a / Synthesis and characterization of LiFePo4/C cathode material by freeze drying method with PVP
(Belgrade : Union of Engineers and Technicians of Serbia, 2014)
Lithium iron phosphate is a promising cathode material for lithium ion battery application thanks to its good characteristics. Here is presented the freeze drying method for the preparation of carbon coated LiFePO4, where ...
