Effects of air-lift reactor dimensions on its hydrodinamic characteristics / Uticaj geometrije pneumatskog reaktora sa spoljašnjom recirkulacijom na njegove hidrodinamičke osobine
(Association of Chemical Engineers of Serbia, 2010)
In this study the hydrodynamic characteristics of the external loop airlift bioreactors were investigated. The influence of reactor height and solid particles concentration on the mean liquid circulation velocity was ...
Intragranular ferrite morphologies in medium carbon vanadium-micro alloyed steel
(University of Belgrade, Technical Faculty, Bor, 2013)
The aim of this work was to determine TTT diagram of medium carbon V-N micro-alloyed steel with emphasis on the development of intragranular ferrite morphologies. The isothermal treatment was carried out at 350, 400, 450, ...
The effect of mechanical activation on synthesis and properties of MgAl2O4 ceramics
(Elsevier Sci Ltd, Oxford, 2019)
Magnesium aluminate, MgAl2O4 and other alumina-based spinels are ceramics with high hardness, high melting point and mechanical strenght. Spinels can also be used as dielectrics in microwave applications. The goal of this ...
Upregulation of Heme Oxygenase-1 in Response to Wild Thyme Treatment Protects against Hypertension and Oxidative Stress
(Hindawi Ltd, London, 2016)
High blood pressure is the most powerful contributor to the cardiovascular morbidity and mortality, and inverse correlation between consumption of polyphenol-rich foods or beverages and incidence of cardiovascular diseases ...
Determination of Degradation Level during Cavitation Erosion of Zircon Based Ceramic
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2017)
Mechanical shock of zircon based ceramic induced by cavitation erosion testing was investigated in this study. Several parameters were followed in order to determine level of material degradation during the cavitation ...
Exploiting the Nonlinear Frequency Response Method to Evaluate the Potential of Forced Periodic Operation of Reactors
(American Institute of Chemical Engineers Annual Meeting (AIChE Annual Meeting), San Francisco, USA, 2016)
Forced periodic operations of chemical reactors possess significant potential to improve numerous performance criteria. The corresponding analysis of reaction systems and the estimation of the magnitude of possible performance ...
Lipases as biocatalysts for biodiesel production / Lipaze kao biokatalizatori u sintezi biodizela
(Association of Chemical Engineers of Serbia, 2010)
Lipases can be used for a variety of biotechnological applications: synthesis of fine chemicals, therapeutics, agrochemicals, cosmetics, flavors, biopolymers and biodiesel. Biodiesel is an alternative fuel for diesel engines ...
Antibacterial and UV protective properties of polyamide fabric impregnated with TiO2/Ag nanoparticles
(Srpsko hemijsko društvo, Beograd, 2015)
The possibility of in situ photoreduction of Ag+ using colloidal TiO2 nanoparticles deposited on the surface of polyamide fabric in the presence of the amino acid alanine and methanol is discussed. The presence of TiO2/Ag ...
Experimental study of the thermodynamic and transport properties of binary mixtures of poly(ethylene glycol) diacrylate and alcohols at different temperatures
(Srpsko hemijsko društvo, Beograd, 2015)
Experimental density rho, refractive index n(D) and viscosity eta data of three binary systems of poly(ethylene glycol) diacrylate (PEGDA) + ethanol, + 1-propanol and + 1-butanol were measured at eight temperatures from ...
Influence of Cr, Mn and Mo on structure and properties of V microalloyed medium carbon forging steels
(Savez inženjera metalurgije Srbije, Beograd, 2010)
The influence of Cr, Mo and Mn on microstructure and mechanical properties of V-microalloyed medium-carbon steels has been studied by means of metallography and mechanical testing. Cr, Mn and Mo addition promotes the ...
