Chemical durability of sintered glass-composite prepared from glass cullet and waste foundry sand
(Metallurgical & Materials Engineering, 2021)
In this study, the glass-composite was prepared using glass cullet and waste foundry sand as raw materials. The powder technology route was employed. The mixtures containing 10-50 wt% of the sand were sintered at T = 750 ...
The mechanism of cathodic electrodeposition of epoxy coatings and the corrosion behaviour of the electrodeposited coatings / Mehanizam kataforetskog taloženja epoksidnih prevlaka i koroziono ponašanje dobijenih prevlaka
(Serbian Chemical Society, Belgrade, 2002)
The model of organic film growth on a cathode during electrodeposition process proposes the current density-time and film thickness-time relationships and enables the evaluation of the rate contents for the electrochemical ...
Histological and immunohistochemical evaluations of rat soft tissue response to bioceramical implants / Histološka i imunohistohemijska procena reakcije mekog tkiva pacova na biokeramičke implante
(Univerzitet u Beogradu - Fakultet veterinarske medicine, Beograd, 2009)
The purpose of this study was to evaluate the tissue response induced by bioceramical materials (BCM) implanted in rat subcutaneous tissue. Thirty two rats were assigned to 6 groups, as following: control group i.e. not ...
A study of the photocatalytic degradation of methomyl by UV light
(Association of the Chemical Engineers of Serbia, 2009)
The photocatalytic degradation of insecticide methomyl in water, using TiO2 and ZnO (Merck), under UV (366 nm) was studied. The influence of the catalyst concentration and pH was investigated. The optimal concentration of ...
Heavy metals concentration in soils from parks and green areas in Belgrade / Koncentracija teških metala u zemljištu parkova i zelenih površina u Beogradu
(Serbian Chemical Society, Belgrade, 2009)
The current study included the investigation of several metals and their distribution in urban soils from parks and green areas in the city of Belgrade. The soils were sampled in January and February 2008. The concentrations ...
Approximation of material behaviour of PLLA polymer in HAp/PLLA biocomposite material using nanoindentation and finite element method
(Savez inženjera metalurgije Srbije, Beograd, 2007)
In this work, a combination of nanoindentation experiment and finite element modeling is proposed in order to obtain approximate material behavior of PLLA polymer in hydroxyapatite (HAp)/poly-L-lactide (PLLA) composite. ...
The immobilization of lipase on Sepabeads: Coupling, characterization and application in geranyl butyrate synthesis in a low aqueous system
(Association of the Chemical Engineers of Serbia, 2008)
Lipase from Candida rugosa immobilized on Sepabeads EC-EP was shown to catalyze the esterification of geraniol with butyric acid in a predominantly organic system. The immobilization procedure was adjusted to optimize the ...
The influence of concentration of Nd-Fe-B powder in composite coating of optical fiber to the sensibility to external magnetic field
(University of Belgrade, Technical Faculty, Bor, 2005)
Multi-mode optical fiber with magnetic composite coating was investigated as an optical fiber sensor element (OFMSE) for magnetic field sensing The composite coating was formed with dispersions of permanent magnet powder ...
Electrochemical synthesis and corrosion behavior of thin polyaniline film on mild steel / Elektrohemijska sinteza i koroziono ponašanje tankih filmova polianilina na mekom čeliku
(Engineering Society for Corrosion, Belgrade, Serbia, 2003)
The electrochemical synthesis of polyaniline (PANI) on mild steel from the sodium-benzoate solutions has been investigated. It has been concluded that thin, highly adherent, polyaniline films could be obtained by anodic ...
Eksperimentalna proizvodnja fermentisanog mlečnog napitka sa probiotičkim svojstvima
(Univerzitet u Beogradu - Poljoprivredni fakultet, Beograd i Poslovno udruženje za stočarstvo - grupacija za mlekarstvo, Beograd, 2002)
Kiselomlečni napici se proizvode fermentacijom laktoze dejstvom bakterija mlečne kiseline. One svojom aktivnošću povećavaju svarljivost proizvoda i sprečavaju aktivnost drugih patogenih mikroorganizama. Poboljšanje efekata ...
