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 ...
Electrochemical synthesis and corrosion behavior of thin polyaniline-benzoate film on mild steel
(Elsevier Science Sa, Lausanne, 2004)
The electrochemical synthesis and corrosion behavior of polyaniline (PANI) on mild steel from sodium-benzoate solutions were investigated. Thin, adherent, polyaniline films were obtained by anodic oxidation with current ...
Influence of electrode material on gas-filled surge arresters characteristics in gamma and X radiation field
(Natl Inst Optoelectronics, Bucharest-Magurele, 2006)
The aim of this paper is to find the possibility for improvement of gas-filled surge arresters (GFSA) characteristics in y and X radiation field by appropriate choice of electrode materials. For that purpose electrodes ...
Preparation and Thermal Stability of Elastomers Based on Irregular Poly(urethane-isocyanurate) Networks
(Taylor & Francis Inc, Philadelphia, 2009)
The objective of this study was to investigate the thermal stability of poly(urethane-isocyanurate) networks with increasing amount of dangling chains. In order to improve thermal stability of elastomeric materials, networks ...
Examination of rheological properties of fine particles as carriers for controlled drug release
(Taylor & Francis Inc, Philadelphia, 2003)
Development of lipid-based fine particles as potential drug carriers requires detailed investigation of possible effects of these carriers on rheological properties of blood. In this study, we have investigated the influence ...
Theoretical investigation of the adsorption of a binary mixture in a chromatographic column using the nonlinear frequency response technique
(Springer, New York, 2007)
The nonlinear frequency response of a chromatographic column for the adsorption of two dissolved components is analyzed using the concept of higher order frequency response functions (FRFs) which is based on the Volterra ...
TPD-MS study of glassy carbon surfaces oxidized by CO2 and O2 / Maseno spektrometrijsko ispitivanje stabilnosti površine staklastog karbona oksidovanog ugljen-dioksidom ili kiseonikom
(Serbian Chemical Society, Belgrade, 2002)
The temperature-programmed desorption (TPD) method combined with mass spectrometric (MS) analysis has been applied to investigate the surface properties of carbon materials. The apparatus consisting of a temperature-programmed ...
Mass transfer between a fluid and an immersed object in liquid-solid packed and fluidized beds / Prenos mase fluid-uronjeni objekat u pakovanim i fluidizovanim slojevima tečnost-čestice
(Serbian Chemical Society, Belgrade, 2005)
The mass transfer coefficient between fluid and an immersed sphere in liquid packed and fluidized beds of inert spherical particles have been studied experimentally using a column 40 mm in diameter. The mass transfer data ...
