The subject of the research in this work was the S49 rail made of R260 rail steel (1.0623). The carried out investigations concern microstructure tests and tests of mechanical properties of rails after several years of exposure in the open air without usage. The purpose of the work was to determine on the basis of the results of research the possibilities of using the tested rail for usage and application for the construction of tracks on railway sidings. For investigations there were used diverse techniques reaching such engineering materials investigations like light or scanning electron microscope for microstructure investigations, as well as hardness and microhardness test were performed for determinations of the microstructural changes occurred in the upper area of the rails surface. The microstructure changes concerns especially the ferritic and pearlitic structure and the breaks in the present carbide mesh. During investigations it was found out that the tested railway rails are fully useful for application, after machining to achieve required dimensional parameters. It is also of high importance, of the economical point of view, that their price, also in case of earlier installation of the rails, may be lower than the current price off ered on the marked for a entire new product. The price diff erence reaches dimensions in the range of 5-10%.

In this study, a novel synthesized pearlite/ferrite/guar gum (PFG) hydrogel was evaluated. Theoretical studies using molecular dynamics simulation through the Forcite module in Material Studio 2017 showed crystal violet (CV) and naproxen (NAP) dye drug adsorption relative to other dyes and drugs. One of the best ways to remove pollutants is adsorption. With the absorption method, harmful contaminants such as CV and NAP can be removed from the water and wastewater cycle. Morphology and functional groups of natural compounds and synthesized materials were determined using FT‐IR, XRD, TGA, VSM, EDX, BET and FE‐SEM analysis. The potential of the hydrogel to effectively remove CV and NAP from a saturated solution was studied experimentally based on the efficiency of adsorbent dose, pH and temperature. The composition follows the PSO kinetically and the Langmuir model in terms of the isotherm. The maximum absorption capacity of CV (244.40 mg/g) and NAP (180.15 mg/g) in hydrogel was investigated. According to the antibacterial activity test, the synthesized hydrogel had no antibacterial properties.
