Mg-Ni na perlitnom nosaču kao hidrogenizacioni katalizator: uticaj sadržaja Mg i Ni / Mg-Ni supported on perlite as hydrogenation catalyst: Influence of Mg and Ni content
(Belgrade : Association of the Chemical Engineers of Serbia AChE, 2019)
Use of broken honeycomb-like expanded perlite as support for magnesium modified nickel catalysts in process of partial hydrogenation of sunflower oil was studied. By the use of the precipitation-deposition method, two ...
On Oscillations and Noise in Multicomponent Adsorption: The Nature of Multiple Stationary States
(Hindawi, 2019)
Starting from the fact that monocomponent adsorption, whether modeled by Lagergren or nonlinear Riccati equation, does not sustain oscillations, we speculate about the nature of multiple steady state states in multicomponent ...
A comprehensive study of conditions of the biodegradation of a plastic additive 2,6-di-tertbutylphenol and proteomic changes in the degrader Pseudomonas aeruginosa san ai
(Royal Society of Chemistry, 2019)
The Pseudomonas aeruginosa san ai strain was investigated for its capability to degrade the 2,6-di-tertbutylphenol (2,6-DTBP) plastic additive, a hazardous and toxic substance for aquatic life. This
investigation was ...
Distribution of major and trace elements in the Kovin lignite (Serbia)
(Institut za Geoloska Istrazivanja, 2019)
A geochemical and mineralogical study was performed on lignite samples from the Upper Miocene Kovin deposit, hosting three coal seams. The Kovin lignite is characterized by high moisture content, medium to high ash yield, ...
Oscillatory Carbonylation of Poly(Ethylene Glycol)Methyl Ether Acetylene. Modelling of Reaction Mechanism and Stoichiometric Network Stability Analysis
(University of Kragujevac, 2019)
The reaction mechanism of palladium-catalysed oscillatory carbonylation of
poly(ethylene glycol)methyl ether acetylene (PEGA) was examined by stoichiometric
network analysis (SNA) of the stability of the dynamic states. ...
Adsorption of nicotine from aqueous solutions on montmorillonite and acid – modified montmorillonite
(International Institute for the Science of Sintering, Beograd, 2019)
Montmorillonite (Mt) and acid modified montmorillonite (MtA) were tested as
nicotine adsorbents. The samples were characterized using FT-IR spectroscopy and low
temperature nitrogen physisorption. Nicotine adsorption was ...
On the properties of hot forged Ti-6Al-4V alloy aimed for surgical implants
(Belgrade : Association of Metallurgical Engineers of Serbia, 2019)
The investigation here is aimed to examine the structural and mechanical changes that might have occurred during the hot forging process, a process to obtain a surgical hip implant, and the subsequent heat treatment. ...
Observations of the genus muelleria (bacillariophyceae) from the Republic of north Macedonia
(Belgique : Societe Royale de Botanique de Belgique, 2019)
Background and aims – An increased interest in the diatom flora from subaerial habitats in the Republic of North Macedonia has revealed the presence of a large number of interesting and often unknown, species. During a ...
Electrochemical and structural properties of Ni(II)-alumina composites as an annealing temperature function
(International Institute for the Science of Sintering, Beograd, 2019)
Alumina powders, pure and doped with nickel, were synthetized by sol-gel method and calcined at 500, 900 and 1100°C in order to obtain mesoporous structures with a high specific surface area, well adapTab. to catalytic ...
Mechanochemically improved surface properties of activated carbon cloth for the removal of As(V) from aqueous solutions
(Elsevier, 2019)
Modified activated carbon cloth is prepared by mechanochemical modification of viscose rayon carbon cloth. The effects of different milling atmospheres, in the air and inert conditions, were investigated. Changes in kind ...
