Statistical modeling and optimization of ultrasound-assisted biodiesel production using various experimental designs / Statističko modelovanje i optimizacija proizvodnje biodizela u prisustvu ultrazvuka primenom različitih eksperimentalnih planova
(Engineering Society for Corrosion, Belgrade, Serbia, 2019)
The present study compares the performances of the regression models developed by the response surface methodology combined with the full factorial, Box-Behnken or face central composite designs applied for the ultrasound-assisted ...
The influence of Mg and Mn content on abnormal grain growth in AA5182 type alloys
(Savez inženjera metalurgije Srbije, Beograd, 2019)
The occurrence of abnormal grain growth (AGG) in AA5182 alloy during annealing imposes severe restrictions on processing parameters and deteriorates mechanical properties. In this work, we investigated the effect of chemical ...
Removal of emerging pathogenic bacteria using metal-exchanged natural zeolite bead filter
(Iwa Publishing, London, 2019)
Hospital wastewaters can become a route for dissemination of antibiotic-resistant bacteria to the environment if not properly treated. Some of these bacteria are able to survive conventional disinfection treatments (e.g. ...
Silicon nanostructuring by Ag ions implantation through nanosphere lithography mask
(Elsevier Science Bv, Amsterdam, 2019)
Nanosphere lithography is an effective technique for high throughput fabrication of well-ordered patterns on large areas. This study reports on nanostructuring of silicon samples by means of Ag ions implantation through ...
Supercritical co2 impregnation of gelatin-chitosan films with clove essential oil and characterization thereof
(Savez hemijskih inženjera, Beograd, 2019)
Supercritical CO2 impregnation process was used for the first time to fabricate biodegradable gelatin-chitosan (G/Ch) films containing dove oil (CO) for potential use in active food packaging. All the impregnations were ...
The influence of synthesis conditions on the redox behaviour of LiFePO4 in aqueous solution
(Elsevier Science Sa, Lausanne, 2019)
To contribute to the knowledge on the influence of synthesis procedure on the intercalation kinetics of lithium ions into phospho-olivines, LiFePO4/C composite samples (LFPC) were synthesized in two ways, the first one in ...
Influence of different concentrations of Zn-carbonate phase on physical-chemical properties of antimicrobial agar composite films
(Elsevier, Amsterdam, 2019)
Agar-based composites with different Zn-carbonate mineral phase content were prepared by in situ mineralization and the solvent casting method. The mineral phase within the composite films was identified as hydrozincite, ...
Non-thermal plasma and ultrasound-assisted open lactic acid fermentation of distillery stillage
(Springer Heidelberg, Heidelberg, 2019)
Stillage is the main by-product of bioethanol production and the cost of its treatment significantly affects the economy of bioethanol production. A process of thermal sterilization before lactic acid fermentation (LAF) ...
Mg/Cu co-substituted hydroxyapatite - Biocompatibility, mechanical properties and antimicrobial activity
(Elsevier Sci Ltd, Oxford, 2019)
The aim of this study was to improve the mechanical properties and to optimize antimicrobial activity of hydroxyapatite (HAP) by simultaneous doping with Mg and Cu ions in order to obtain material that would be able to ...
Numerical simulation of fatigue crack propagation: A case study of defected steam pipeline
(Elsevier Ltd, 2019)
In order to prevent the premature failure of steam pipeline produced of molybdenum-vanadium steel, the experimental tests were performed to measure fracture toughness and to determine the mechanical behaviour of cracked ...
