This article deals with the analysis of the adsorptive properties of the waste produced during theshot blasting of castings in foundries. During this process, particles of moulding mixture andscale that remained on the surface of the casting after removal from the mould are removed. Sincethis waste contains particles of moulding mixture (SiO2, carb...

The particle shape and size of the starting powders represent the most important physicalproperties, on which the quality of the compacts and final sintered products depends. Two types ofpowder were analyzed in the paper - electrolytic copper powder with a dendritic particle shape andwater-atomized copper powder with an irregular particle shape. Th...

Many alloys exhibit the shape memory effect, but only the Cu-Al-Zn, Cu-AI-Ni, and Ni-Ti alloysare presentand of commercial importance. The greatest use of these alloys is in biomedicine(filters, orthodontic implants, guide wires for catheters, etc.). Shape-memory alloys may be foundin sensors in automobiles, consumer products, and generally in smar...

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

In the paper, the influence of the cutting conditions (cutting speed, feed, and depth of cut) duringthe machining of the cylindrical steel part on the surface roughness (average surface roughness-Ra) is analysed using experimental investigation. The material used in the full factorialexperimental investigation was C45 steel, a diameter of 50 mm, ma...

Considering the toxic properties of heavy metals and their effects on the environment, there is anincreasing interest in studying their interactions with different ligands and searching forpossibilities to remove those ions from the environment. Compared to other ligands, crown etherspossess the highest selectivity as ligands for metal cations, due...
