Structure and kinetics of internal oxidation in Ag-Sn alloys / Struktura i kinetika interne oksidacije Ag-Sn legura
(Savez inženjera metalurgije Srbije, Beograd, 2008)
Internal oxidation in Ag-Sn-In-Te and Ag-Sn-Cu-Bi alloys was tested. micro structures of casted and homogenized samples, as well as after internal oxidation were followed by optical microscopy. The structure of Ag-Sn-Cu-Bi ...
Microbial Polysaccharides and their Derivatives as Current and Prospective Pharmaceuticals
(Bentham Science Publ Ltd, Sharjah, 2008)
The ability to produce polysaccharides is widely found among microbial species. The structural diversity of the microbial polysaccharides (MPS) leads to a wide diversity of their applications. This review focuses pharmacological ...
Laboratory investigation of cavitation resistance of materials: Modified ultrasonically induced cavitation test method / Laboratorijsko istraživanje kavitacione otpornosti materijala - modificirana ultrazvučna metoda
(Savez inženjera metalurgije Srbije, Beograd, 2008)
Cavitation erosion represents an actual problem in machines, whose components such as propellers, blades of hydraulic pumps and turbines, are exposed to high-speed flow of liquid. Research exhibited that hydraulic machinery ...
Structural and electrical properties of the 2Bi2O3·3ZrO2 system
(Journal of Solid State Chemistry, 2008)
Powder mixtures of α-Bi2O3 (bismite) and monoclinic m-ZrO2 (baddeleyite) in the molar ratio 2:3 were mechanochemically and thermally treated with the goal to examine the phases, which may appear during such procedures. The ...
Determination of glass temperature of polymers by inverse gas chromatography
(Elsevier, Amsterdam, 2008)
Inverse gas chromatography (IGC) is an attractive technique for polymer characterization due to possible simultaneous determination of various physicochemical properties of polymer systems merely from retention times of ...
Corrosion protection of aluminum by vinyltriethoxysilane coatings / Koroziona stabilnost prevlaka viniltrietoksisilana
(Engineering Society for Corrosion, Belgrade, Serbia, 2008)
In this work the influence of the deposition parameters, i.e. silane solution concentration, deposition time and curing time on the corrosion stability of vinyltriethoxysilane (VTES) coatings on aluminum was investigated. ...
Optimization of the production of biodiesel by a commercial immobilized lipase in a solvent-free system using a response surface methodology / Optimizovanje postupka proizvodnje biodizela komercijalnom lipazom u sistemu bez organskog rastvarača primenom metodologije odzivnih površina
(Serbian Chemical Society, Belgrade, 2008)
Response surface methodology was used for the evaluation of the effects of various factors on the synthesis of biodiesel catalyzed with immobilized lipase from Rhizomucor miehei in a solvent-free system. The production of ...
The thermal stability of poly(methyl methacrylate) prepared by RAFT polymerisation / Termička stabilnost poli(metil metakrilata) sintetisanog RAFT polimerizacijom
(Serbian Chemical Society, Belgrade, 2008)
Poly(methyl methacrylate), PMMA, was prepared by reversible addition-fragmentation chain transfer, RAFT, polymerisation using 2-(2-cyanopropyl)-dithiobenzoate, CPDB, as the RAFT agent. The thermal stability of the resulting ...
A study of the primary crystallization of a mixed anion silicate glass
(Elsevier Science Bv, Amsterdam, 2008)
This paper presents the results of a study of the primary crystallization of a multicomponent mixed anion silicate glass. The primary phase, leucite, and the secondary phase, diopside, were formed by surface crystallization, ...
Prediction of excess molar volumes of binary mixtures of organic compounds from refractive indices
(Versita, Warsaw, 2008)
The excess molar volumes of 51 binary mixtures containing diverse groups of organic compounds: alcohols (methanol, ethanol, propan-1-ol, butan-1-ol, pentan-1-ol, hexan-1-ol, and heptan-1-ol), (cyclo-) alkanes (hexane, ...
