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 ...
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 ...
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 ...
Influence of boron doping on characteristics of glucose-based hydrothermal carbons
(Journal of the Serbian Chemical Society, 2022)
In this study, the influence of boron doping on structural and surface properties of carbon material synthesized by a hydrothermal method was investigated, and the obtained results were compared with the previously published ...
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 ...
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 ...
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 ...
Air Cooler for Crystal Growth in a Laboratory Tube Furnace
(Pleiades Publishing, 2022)
A new air cooler design (“specific two-level crystallization incubator”) with a specific arrangement of laboratory vessels by levels and double-branch air conductors at the ends and a series of movable cold thresholds ...
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 ...
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 ...
