In the scope of this thesis, I focused on SrTiO3 (ST)-based dielectric ceramic composites as a lead-free perovskite material, which holds great potential for use in various electronic components. Such materials are large-scale and fabricated under high energy requirements, indicating an increasing need for a more environmentally friendly processing method. …
Alkali activation is a chemical process in which aluminosilicate-rich materials that dissolve in basic media at room temperature form binding phases by polycondensation. Alkali-activated materials (AAM), also called geopolymers, are inorganic aluminosilicate-based materials produced mainly from fly ashes and metallurgical slags or clays with high Al and Si content and …
A new approach for the synthesis of silver (Ag), platinum (Pt) and gold (Au) nanoparticles and their composites with hydroxyapatite (HAp) is developed via a sonochemical process. The major goal was to design physicochemical properties of material in order to achieve: (i) intensive antibacterial activity and (ii) maximal reduction of …
