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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
