Innovative environmentally friendly technology for copper(II) hydroxide production
(Savez hemijskih inženjera, Beograd, 2018)
The innovative laboratory procedure for the synthesis of copper(II) hydroxide in the form of the aqueous suspension was developed. The reaction mechanism consists of the reaction between copper(II) sulphate pentahydrate ...
Solvatochromism of 5-(4-substituted arylazo)-4-phenyl-6-methyl-3-cyano-2-pyridones / Solvatohromizam 5-(4-supstituisanih arilazo)-4-fenil-6-metil-3-cijano-2-piridona
(Engineering Society for Corrosion, Belgrade, Serbia, 2018)
Eight 5-(4-substituted arylazo)-4-phenyl-6-methyl-3-cyano-2-pyridones were synthesized by reaction of benzoylacetone and arendiazonium salt, followed by condensation with cyanoacetamide. Absorption spectra of all azo ...
CO2 conversion enhancement in a periodically operated Sabatier reactor: Nonlinear frequency response analysis and simulation- based Study
(The 25th International Symposium of Chemical Reaction Engineering (ISCRE 25), Florance, Italy, 2018)
Nonlinear frequency response (NFR) analysis was applied on a Sabatier reactor. A substantial improvement in CO2 conversion was predicted under certain conditions. The NFR analysis prediction was validated using a kinetic ...
Tomato pomace powder as a raw material for ketchup production
(Elsevier Science Bv, Amsterdam, 2018)
A value-added ketchup from tomato pomace powder was developed and compared to a previously developed ketchup from fresh tomato pomace. The total dietary fiber content of tomato pomace powder ketchup was higher than fresh ...
Cross-Linkable Modified Nanocellulose/Polyester Resin-Based Composites: Effect of Unsaturated Fatty Acid Nanocellulose Modification on Material Performances
(Wiley-VCH Verlag Gmbh, Weinheim, 2018)
Unsaturated fatty acid (FA)-modified nanocellulose (m-NC) shows potential application in improving mechanical properties of unsaturated polyester/m-NC nanocomposites (UPe/m-NC). A polyester matrix is obtained by polycondensation ...
New surface characterization tools for alumina based refractory material exposed to cavitation - Image analysis and pattern recognition approach
(Elsevier Science Inc, New York, 2018)
The aim of this study was to examine the influence of cavitation erosion on the morphology of defects formed on the surfaces of alumina-based materials. The alumina-based samples were exposed to cavitation erosion for 42 ...
Non-Isothermal Crystallization of Lithium Germanophosphate Glass Studied by Different Kinetic Methods
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2018)
Crystallization kinetics of 22.5Li(2)O center dot 10Al(2)O(3)center dot 30GeO(2)center dot 37.5P(2)O(5) (mol%) glass was studied under non-isothermal condition using the differential thermal analysis (DTA). The study was ...
Separation of Cu(II) ions from synthetic solutions and wastewater by raw and calcined seashell waste
(Desalination Publ, Hopkinton, 2018)
The limestone and lime are agents widely used for separation of toxic metals from contaminated water. To reduce the exploitation of natural limestone deposits, appropriate replacements are sought out among the waste materials ...
A linear and non-linear polynomial neural network modeling of dissolved oxygen content in surface water: Inter- and extrapolation performance with inputs' significance analysis
(Elsevier Science Bv, Amsterdam, 2018)
Accurate prediction of water quality parameters (WQPs) is an important task in the management of water resources. Artificial neural networks (ANNs) are frequently applied for dissolved oxygen (DO) prediction, but often ...
Effect of compositional data in the multivariate analysis of sterol concentrations in river sediments
(Elsevier Science Bv, Amsterdam, 2018)
In this paper, multivariate analysis of sterol concentrations detected in river sediment samples was performed. In order to remove co-dependence of values, concentrations of sterols were transformed using centered log-ratio ...
