Green corrosion inhibitors of steel based on peptides and their constituents: a combination of experimental and computational approach
(Springer Science and Business Media Deutschland GmbH, 2023)
In this work, six groups of non-toxic compounds were tested as inhibitors for mild steel in 1 M HCl solution: glycine (Gly), glutamic acid (Glu), cysteine (Cys), a mixture of three amino acids glycine, glutamic acid, and ...
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 ...
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 ...
Adsorptive pretreatment of waste cooking oil using quicklime for fatty acid methyl esters synthesis
(Association of the Chemical Engineers of Serbia, 2023)
Synthesis of biodiesel from various plant oils is realized by the transesterification of triglycerides with methanol or by a reaction usually defined as methanolysis. The usage of low-quality oils, such as waste cooking ...
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 ...
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 ...
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 ...
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 ...
