This study evaluates three hybrid electrocoagulation (EC) processes with aluminium electrodes:EC-zeolite process (EC+Z), EC-zeolite-ultrasound-assisted process (EC+Z+US), and EC-zeolitemagnet-assisted process (EC+Z+MAG) for compost wastewater treatment with a large content oforganic matter. The focus was on evaluating the effects of these processes...

Phytoremediation with wild plant species could be an environmentally friendly and economicalsolution. Selected wild plants like mint, oregano, chamomile, nettle, and St. John’s wort, from ruralareas in Bosnia and Herzegovina, were collected, lyophilized, and acid-digested for heavy metalsanalysis. Nickel (Ni), copper (Cu), chromium (Cr), cadm...

The increasing need for sustainable resource utilization has driven the exploration of waste-derived materials for industrial applications. This study investigates the valorization of cattle bone waste into high-purity hydroxyapatite-rich bone ash and its application in ceramics. The beneficiation process involved boiling, drying, controlled calcin...

This study presents the development of an eco-efficient laboratory-scale production route for longsteel products, focusing on sustainable casting and hot deformation processes. Conventionalcasting using 80x80 mm molds and gravity filling generated significant shrinkage defects, leadingto scrap generation, repeated melting, and reduced material effi...

Monitoring cavitation erosion in materials is crucial for their performance in environmentscharacterized by severe fluid flow conditions. Materials such as metals, ceramics, and composites,commonly used in these applications, must possess specific mechanical properties to effectivelyresist cavitation erosion. Additionally, various environmental fac...

The translational symmetry of the distribution of atoms (ions) of the charge carriers (electrons or holes) system is broken by sputtering (doping) due to the existence of two boundary surfaces. This is a model of high-temperature superconductors in which the observed symmetry breaking orthogonal to the CuO plane is treated as a perturbation. Single...

Metallic materials in granular packings show different electrical properties from their bulk counterparts. In this paper, we investigate the temporal evolution of the electrical conductivity of granular metals. We use metallic beads arranged in different one-, two- and three-dimensional ensembles through which different constant currents are inject...

This study investigated the mechanical properties of a series of Fe-Cr-Mn (Mo)-N alloys. The chromium content ranged from 16 to 18 mass %. The test alloys were produced by adding nitrided ferroalloys during melting in an induction furnace. Test specimens of each alloy were prepared for mechanical testing and microstructural observation. Tensile str...

Shape memory alloys are of great commercial importance from biomedical applications to smart materials. The electrochemical behavior of Cu-Al-Zn alloy in phosphate buffer without and in the presence of amino acid was investigated. Electrochemical researches were performed in a traditional three-electrode system by means of the Tafel extrapolation m...
