Poster presented at the 14th International Conference on Photoacoustic and Photothermal Phenomena, Cairo, Egypt, January 6-9, 2007
On the kinetics of the hydrogen evolution reaction on zinc in sulfate solutions
(Belgrade : Serbian Chemical Society, 2001)
The kinetics and mechanism of the hydrogen evolution reaction (her) were studied on zinc in 1.0 mol dm-3 Na2SO4 at 298 K, in the pH range 4.4 - 10. It was found that a combination of classical potentiostatic steady-state ...
Geometrical and electrical properties of NTC polycrystalline thermistors vs. Changes of sintering parameters
(Belgrade : International Institute for the Science of Sintering, 2006)
NTC thermistor powder was made of a Mn, Ni, Fe and Co oxide mixture calcinated at 1050°C / 60 min. The powder was milled in a ball mill down to an average particle diameter of 0.9 μm. Small disc shaped pills of the powder ...
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 ...
Intrinsic resistivity of sintered Nickel Manganite vs. powder activation time and density
(Belgrade : International Institute for the Science of Sintering, 2008)
In this work the DC resistivity of sintered nickel manganite NiMn2O4 (NTC thermistor material) was studied as a function of additional powder activation time in a planetary ball mill (0, 5, 15, 30, 45 and 60 min). The ...
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 ...
Sinteza i dizajniranje strukture i osobina hidroksiapatit/polilaktid kompozitnih biomaterijala
(Belgrade : University of Belgrade, Faculty of Technology and Metallurgy, 2001)
Koštani defekti mogu se reparisati biomaterijalima na bazi sintetskog hidroksiapatita (HAp). U slučaju reparacije koštanih defekata sa prekidom kontinuiteta, neophodno je da upotrebljeni biomaterijal zadovolji biomehaničke ...
PDLLA Microparticles Containing BSA: Effect of Formulation Variables on Size Distribution
Poster presented at the 9th Conference of the Yugoslav Materials Research Society - YUCOMAT 2007, Herceg Novi, Crna Gora, September 10-14, 2007.
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 ...
