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 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...

Steel 17-7PH is austenitic-martensitic steel with high strength, hardness, and resistance to creep, and corrosion. It is designed for aerospace components, but can also be used for other applications that require high strength and corrosion resistance, as well as leaf springs for operation at temperatures up to 316 °C. It can be used in a solut...

The assessment of workplace hazards involves recognizing the likelihood of occurrence and the severity of potential injuries or occupational diseases to employees. The risk assessment is performed by a team of experts from various scientific and professional fields to objectively evaluate the attributive and/or numerically expressed level of risk, ...

In this article we present the original Georgi-Glashow  model with gauge and fermion sector derivation in order to show grand unified theory (GUT) through this model, but also to correlate  and Standard Model (SM). One of the correlations reside in neutrino mass sector where both and Standard Model (SM) see neutrinos as massless particles...

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...
