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 ...
Cellulases: From Lignocellulosic Biomass to Improved Production
(MDPI, 2023)
Cellulases are enzymes that are attracting worldwide attention because of their ability to degrade cellulose in the lignocellulosic biomass and transform it into highly demanded bioethanol. The enzymatic hydrolysis of ...
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 ...
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 ...
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 ...
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 ...
Physics of collective cell migration
(Springer Science and Business Media Deutschland GmbH, 2023)
Movement of cell clusters along extracellular matrices (ECM) during tissue development, wound healing, and early stage of cancer invasion involve various inter-connected migration modes such as: (1) cell movement within ...
Mechanistic insights into the simultaneous visible-light induced photodegradation of organic pollutants by g-C3N4/titanate heterojunction
(Springer Science and Business Media B.V., 2023)
The visible-light-active heterojunctions based on TiO2 were extensively investigated due to their wide range of energy and environment applications. In this study, g-C3N4/titanate heterojunction photocatalyst was successfully ...
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 ...
