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 ...
In silico–in vitro estimation of lipophilicity and permeability association for succinimide derivatives using chromatographic anisotropic systems and parallel artificial membrane permeability assay
(Biomedical Chromatography, 2022)
Passive permeability is one of the key features that determine absorbability and one of the most studied properties in the early phases of drug development. Newly synthesized succinimide derivatives from two different ...
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 ...
Thermo-mechanical analysis of linear welding stage in friction stir welding Influence of Welding Parameters
(VINČA Institute of Nuclear Sciences, 2022)
The influence of friction stir welding parameters on thermo-mechanical behavior of the material during welding is analyzed. An aluminum alloy is considered (Al 2024 T351), and different rotating and welding speeds are ...
Forced Periodic Operation of Methanol Synthesis in an Isothermal Gradientless Reactor
(John Wiley and Sons Inc, 2022)
Methanol synthesis from synthesis gas with heterogeneous Cu/ZnO/Al2O3 catalysts in an isothermal gradientless reactor is described. In a theoretical study, the potential of forced periodic operation (FPO) for improving ...
Influence Of Radiation On The Stability Of Electrical Filters Characteristics As Components For Overvoltage Protection
(Vinca Inst Nuclear Sci, 2022)
The paper represents the results of testing the effect of neutron and gamma radiation of radioactive 60 Co on electrical filters. Neutron and gamma radiation was chosen because of its conductivity. The analysis of the ...
Structural Design of Safety Steel Device of Railway Vehicles Through Analytical and Experimental Investigations
(Budapest Tech Polytechnical Institution, 2022)
The subject of this paper is the structural design of a safety steel device that is located between the standard wagon buffer and the collision energy absorber. The safety steel device is a sacrifical part able to withstand ...
Optimization of the extraction of antioxidants from stinging nettle leaf using response surface methodology
(Macedonian Journal of Chemistry and Chemical Engineering, 2022)
The aim of this study was to optimize the parameters for the extraction of total flavonoids from stinging nettle leaf. Comparison of the effects of different solvents on total flavonoid content showed that, regardless of ...
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, ...
