Heat transfer by liquid convection in particulate fluidized beds / ПРЕНОС ТОПЛОТЕ КОНВЕКТИВНИМ МЕХАНИЗМОМ У ПАРТИКУЛАТИВНО ФЛУИДИЗОВАНОМ СЛОЈУ
(Serbian Chemical Society, 2022)
In this work the theoretical model for heat transfer from a wall to a liquid-solid fluidized bed by liquid convective mechanism has been proposed and developed. The model is based on thickness of boundary layer and film ...
Modification of Structural-Textural Properties of Sulfide Minerals at Polymetallic Concentrate Leaching with Sulfuric Acid and Hydrogen Peroxide Solutions
(Pleiades journals, 2022)
This paper examines the effects of structural-textural characteristics of sulfide minerals on their leaching from polymetallic concentrates with sulfuric acid and hydrogen peroxide solutions. The polymetallic concentrate ...
Synthesis of the new lost foam refractory coatings based on talc
(Journal of the Serbian Chemical Society, 2022)
This paper is focused on the preparation procedures, using a talc-based filler, to improve the rheologic properties of the lost foam refractory coatings. Talc, with grain size of 40 .m, was mechanically activated in a ...
Desulphurisation of dibenzothiophene and 4,6 – dimethyl dibenzothio-phene via enhanced hydrogenation reaction route using RePd–TiO2/SiO2 aerogel catalysts: Kinetic parameters estimation and modelling / Desulfurizacija dibenzotiofena i 4,6 – dimetildibenzotiofena procesom hidrogenovanja uz korišćenje RePd–TiO2/SiO2 aerogel katalizatora: proračun kinetičkih parametara i simulacijaprocesa
(Association of the Chemical Engineers of Serbia, 2022)
Re/Pd-TiO2/SiO2 aerogel catalysts were synthesized by using a sol-gel method and supercritical drying in excess solvent and investigated in the reaction of hydrodesulphurisation (HDS) of dibenzothiophene (DBT) and 4,6-dimethyl ...
Examination and optimization of lignocellulolytic activity of Stereum gausapatum F28 on beechwood sawdust supplemented with molasses stillage
(Serbian Chemical Society, 2022)
This study provides a detailed analysis of the lignocellulolytic activity of a new isolate Stereum gausapatum F28, a Serbian autochthonous fungi, on beechwood sawdust supplemented with cheap waste, sugar beet molasses ...
Supercapacitive properties of the alkali metal hydroxides-activated carbons obtained from sucrose / СУПЕРКАПАЦИТИВНА СВОЈСТВА УГЉЕНИЧНИХ МАТЕРИЈАЛА ДОБИЈЕНИХ ИЗ СAХАРОЗЕ И АКТИВИРАНИХ ХИДРОКСИДИМА АЛКАЛНИХ МЕТАЛА
(Serbian Chemical Society, 2022)
The influence of different hydroxides, applied to activate carbon black, on the electrochemical properties of activated carbon was investigated. The carbon material was prepared by hydrothermal treatment of sucrose and ...
Selectivity of polyclonal repertoire of anti-microbial IgA and its subclasses in saliva and serum in humans
(John Wiley and Sons Inc, 2022)
Increased interest in microbiota calls for the thorough analysis of antibody reactivity to different microorganisms. As salivary IgA represents the first line of defence against microorganisms contacting mucosal surfaces, ...
Hardness and corrosion resistance of Zn−Mn/Al2 O3 composite coatings produced by electrochemical deposition
(National Institute of Science Communication and Policy Research, 2022)
The aim of this study is development and characterization of the novel Zn-Mn/Al2O3 composite coatings. The coatings were electrodeposited with constant current density on steel, from chloride solution, without any commercial ...
Ticagrelor Determination via Its Electrooxidation as the Standard, in Tablets and the Spiked Human Serum at Au Solid Electrode
(ESG, 2022)
Ticagrelor hydrochloride (TCG) is effective in platelet inhibition and useful for preventing cardiovascular death, myocardial infarction, or ischaemic stroke. The drug standard was investigated by cyclic voltammetry (CV) ...
Microstructure, hardness and fracture resistance of P235TR1 seam steel pipes of different diameters / Otpornost prema lomu, tvrdoća i mikrostruktura šavnih cevi različitog prečnika izrađenih od čelika P235TR1
(Association of the Chemical Engineers of Serbia, 2023)
Steel pipelines in industrial plants consist of different elements, including seamless and/or welded (seam) pipes. Properties of welded pipes, including their fracture behaviour, depend on the characteristics of both, the ...
