Adsorption of itaconic acid from aqueous solutions onto alumina / Adsorpcija itakonske kiseline iz vodenih rastvora na aluminijum-oksidu
(Serbian Chemical Society, Belgrade, 2008)
Itaconic acid, IA (C5H6O4), was investigated as a potential flocculant for the aqueous processing of alumina powders. The adsorption of IA, as a function of its concentration and pH value of the solution, onto the alumina ...
Lipase-catalyzed biodiesel synthesis with different acyl acceptors / Primena novih acil akceptora u procesu enzimski katalizovane sinteze biodizela
(Faculty of Technology, Novi Sad, 2008)
Biodiesel is an alternative fuel for diesel engine that is environmentally acceptable. Conventionally, biodiesel is produced by transesterification of triglycerides and short alcohols in the presence of an acid or an ...
Hysteretic behavior modeling of elastoplastic materials / Modeliranje histerezisnog ponašanja elastoplastičnih materijala
(Serbian Society of Mechanics & Mathematical Institute of the Serbian Academy of Sciences and Arts, Belgrade, 2008)
In the present paper the Preisach model of hysteresis is applied to model cyclic behavior of elasto-plastic material. Rate of loading and viscous effects will not be considered. The problem of axial loading of rectangular ...
Phenomenological modelling tools for orthopaedic tissue engineering
(European Cells and Materials, 2008)
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 ...
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 ...
The effect of compositional variations on the fracture toughness of 7000 al-alloys
(Institute of Metals and Technology, 2008)
To provide an understanding of how compositional variations affect the microstructural parameters associated with coarse intermetallic (IM) particles and the fracture toughness in AA 7000 aluminum forgings, a microstructural ...
Characterization and degradation of pectin derived from Budimka apple / Degradacija i karakterizacija pektina jabuke sorte budimka
(Serbian Chemical Society, Belgrade, 2008)
The characterization of apple pectin and its oligogalacturonic fractions derived from the autochthones apple variety Budimka, characteristic for central Serbia, is described in this paper. After extraction, the apple pectin ...
Viscosity of binary non-electrolyte liquid mixtures: Prediction and correlation
(Association of the Chemical Engineers of Serbia, 2008)
The viscosity of 31 binary liquid mixtures containing diverse groups of organic compounds, determined at atmospheric pressure: alcohols, alkanes (cyclo and aliphatic), esters, aromatics, ketones etc., were calculated using ...
