GEOSPATIAL MAPPING OF ECOLOGICAL RISK FROM POTENTIALLY TOXIC ELEMENTS IN SOIL IN THE PANNONIAN-CARPATHIAN BORDER AREA SOUTH OF THE DANUBE
(Carpathian Association of Environment and Earth Sciences, 2022)
This study collected agricultural surface soil samples from 200 sites in the district of Braničevo, located in the Carpathian Mountains – Pannonian Basin south of the Danube River (Serbia). The main objective was to determine ...
Influence of N doping on structural and photocatalytic properties of hydrothermally synthesized TiO2/carbon composites
(Journal of the Serbian Chemical Society, 2023)
Abstract: N-doped TiO2/carbon composites (TiO2/CN) with different nitrogen content, were obtained starting from titanium isopropoxide and glucose, and by varying the amount of melamine, added to starting reaction mixture. ...
Processing of Data Obtained by the Testing of Steel under Low Cyclic Fatigue (Part I)
(University of Zagreb Faculty of Mechanical Engineering and Naval Architecture, 2022)
The design of mechanical components exposed to fatigue load, at a low number of cycles, requires knowledge of the behaviour of the material under the impact of variable load in conditions of controlled strain when cyclic ...
Disparate soil textures as a native medium for As(V) and Pb(II) separation from aqueous systems
(Desalination Publications, 2022)
This study investigated the use of different natural raw soil materials as low-cost adsorbents for
the removal to remove As(V) and Pb(II) from aqueous systems. It deals with the effect of different soil textures, sandy ...
INFLUENCE OF ELECTRODEPOSITION REGIME AND Sn:Pd RATIOS IN Sn-Pd ELECTROCATALYSTS ON ETHANOL OXIDATION REACTION / ВЛИЈАНИЕ НА РЕЖИМОТ НА ЕЛЕКТРОДЕПОЗИЦИЈАТА И НА ОДНОСИТЕ НА Sn:Pd ВО Sn-Pd-ЕЛЕКТРОКАТАЛИЗАТОРИТЕ ВРЗ ОКСИДАЦИЈАТА НА ЕТАНОЛОТ
(Society of Chemists and Technologists of Macedonia, 2023)
A series of bimetallic Sn-Pd catalysts were prepared by a template-free two step electrodeposition method. According to this method, Sn was electrodeposited firstly in potentiostatic or galvanostatic regime on Cu electrodes ...
Ultrasound-assisted extraction of essential and toxic elements from pepper in different ripening stages using Box–Behnken design
(John Wiley and Sons Inc., 2022)
The influence of extraction parameters on the ultrasonically assisted extraction (UAE) of K, Na, Ca, Mg, Zn, Cu, Fe, Mn, Cr, Se, Mo, Li, Al, B, Pb, Hg, Cd, As, and Ni was studied to determine the conditions when a minimum ...
Investigation of electrohydrodynamic calculations / Ispitivanje elektrohidrodinamičkih proračuna
(Savez hemijskih inženjera Srbije, 2022)
A perfect dielectric model was incorporated into the OpenFOAM® software and used for investigation and, possibly, improvements of electrohydrodynamic calculations. Two different sets of numerical simulations were analyzed, ...
Experimental Determination of the Critical Value of the J-Integral that Refers to the HSLA Steel Welded Joint
(Strojarski Facultet, 2023)
Fracture mechanics, as a scientific discipline dealing with the study of cracks in welded structures, has defined parameters and introduced new test methods in order to better determine the tendency to crack growth, critical ...
Beech sawdust based adsorbents for solid-phase extraction of pesticides and pharmaceuticals
(Serbian Chemical Society, 2022)
Carbonaceous solid-phase extraction (SPE) sorbent, efficient in isol-ation and enrichment of multiclass pesticides and pharmaceuticals from water, was synthesized starting from cheap waste beech sawdust and using KOH as ...
J-integral Analysis of the Simulated Heat-affected Zone of the Elevated-temperature Martensitic Steel
(Experimental Techniques, 2022)
Due to its superior strength at high temperatures P/T91 steel is often applied in the chemical, petrochemical and fossil-fired power generation industries. The high strength is achieved by a suitable martensitic microstructure ...
