Deformation pattern and strain hardening in a highly textured 8090 Al-Li alloy sheet
(Elsevier Science Sa, Lausanne, 2000)
Structure-deformation pattern analysis was made on a highly textured 8090 AI-Li alloy sheet deformed in tension. It is shown that the sharp beta-fiber type crystallographic texture induces a strong orientation variation ...
Study of chlorination of nickel silicate by gaseous chlorine and calcium chloride in the presence of active additives
(Wiley, Hoboken, 2000)
The paper presents a thermodynamic analysis and experimental research on the kinetics of the chlorination of nickel silicate (2NiO x SiO2) by gaseous chlorine and calcium chloride without additives and in the presence of ...
Structural characteristics of some ternary Ag-In-Sn alloys
(Savez inženjera metalurgije Srbije, Beograd, 2008)
The Ag-In-Sn system, as one of potential lead-free solder materials, was studied in this paper. The investigated alloys were chosen from two sections, with molar ratio of In:Sn equal to 1:4; 1:2. DTA, XRD, SEM and micro ...

(Univerzitet u Beogradu - Medicinski fakultet, Beograd, 2008)
In this paper an account of biocompatibility of a hormonactive fiber in the form of biologically active complex chitosan-insulin is presented. The behavior of artificial depots of insulin containing 180-330mg of insulin ...
Removal of aqueous manganese using the natural zeolitic tuff from the Vranjska Banja deposit in Serbia
(Elsevier, Amsterdam, 2009)
The natural zeolite tuff from the Vranjska Banja deposit (Serbia) has been studied as sorbent for Mn(II) ions from aqueous solutions. The zeolite sample containing mainly clinoptilolite (more than 70%) removes Mn(II) ions ...
Wetting properties of hemp fibres modified by plasma treatment
(Taylor & Francis Inc, Philadelphia, 2007)
The influence of dielectric barrier discharge (DBD) on the physico-chemical properties of hemp fibres was studied in this paper. Plasma-modification of hemp fibres was performed at atmospheric pressure. The source of the ...
Energijski potencijali u svetu i njihov značaj u celulozno-papirnoj industriji / Energy potentials worldwide and their importance in cellulose and paper industry
(Association of Chemical Engineers of Serbia, 2008)
Radom se ukazuje na raspoložive svetske izvore energije. Razmatra se korišćenje
energije u narednom periodu. Daje se pregled, upotreba i značaj alternativnih
izvora energije. Potencira se neophodnost razvoja novih ...
Structural characteristics of bright copper surfaces
(Journal of Electroanalytical Chemistry, 2001)
In this work, the structures of copper surfaces polished mechanically and polished both mechanically and electrochemically, as well as copper coatings obtained in the presence of basic and top brightening addition agents ...
Preparation and characterization of iron(III) phosphate-oxalate using 1,2-diaminopropane as the structure-directing agent
(Elsevier, Amsterdam, 2002)
Iron(III) phosphate-oxalate (FePO-DAP) crystallizes from a clear solution containing 1,2-diaminopropane (DAP) and oxalic acid at 120 degreesC under hydrothermal conditions. Doubly protonated DAP is present inside a large ...
Spectrophotometric study of the anodic corrosion of Ti/RuO2 electrode in acid sulfate solution
(Elsevier Ltd., 2004)
Electrochemical properties of RuO2-based electrode, particularly the oxygen evolution and anodic dissolution of RuO2 have been investigated in 0.5 mol dm-3 H2SO4 solution by means of polarization measurements and product ...
