Barium zirconate titanate-barium calcium titanate 0.5Ba(Zr0.2Ti0.8)O3-0.5(Ba0.7Ca0.3)TiO3 (BZT-BCT) ceramic exhibits a high piezoelectric response in the vicinity of room temperature. It is an environment-friendly alternative to Pb(Zr1-xTix)O3 (PZT), the most used ceramic material in piezoelectric applications. Thin films meet the requirements related to the miniaturization of electronic components such as in …

In this doctoral thesis influence of different temperatures (5 °C - 60 °C) on the hydration of belite-ye’elimite-ferrite cement was studied. Fluctuations in temperature can cause changes in the phase assemblage, kinetics of hydration and mechanical properties. Besides temperature, other factors such as the cement clinker phase composition, calcium sulfate …

The potential toxicity of nanoparticles in our environment and consumer products is currently determined by costly and timely animal-based testing, which limits the rate of nanoparticle testing, causing a desperate need for alternative testing strategies. A promising alternative – mechanism-based prediction – employs a set of high-throughput cell-based tests that …

SrTiO3 (STO) thin films are used as buffer layers that enable epitaxial integration of various functional oxides with silicon. When pulsed laser deposition (PLD) is used to grow STO on Si, a thin amorphous layer is formed at the STO-Si interface that limits the use of such heterostructures in certain …

Nuclear fusion offers a prospect of a safe, economical and environmentally friendly source of energy. For the advanced concepts of nuclear fusion, SiC-based fibre reinforced composites were proposed as a structural material for the first wall of the reactor vessel, enabling higher operating temperatures and efficiencies. Already developed techniques for …

Presented work is a study of magnetic iron oxide (referred to as spinel) coating synthesis. The coatings were synthesized on the surfaces of selected core nanoparticles with heterogeneous nucleation during the co-precipitation of the Fe3+/Fe2+ ions. The work is divided into three parts. The first part comprise the synthesis of …

One-dimensional hydrothermally synthesized nanostructures such as nanotubes and nanobelts composed of layered titanates from A2TinO2n+1 family have attracted great interest due to their high specific surface area, ion-exchange ability and semiconducting properties, which make them promising candidates for potential applications in the field of catalysis, gas sensors, dye-sensitized solar cells, …

With emerging need for orthopaedic implants and prolonged exposure of organism to implants also problems connected to elution of metal ions that in some cases cause adverse reactions in the human body, emerge. The main aim of our work was therefore to investigate the potential of silicon carbide (SiC) to …

The application of magnetic nanoparticles in biomedicine dictates the preparation of properly arranged nanoparticles. The preparation of a stable colloidal suspension of nanoparticles in complex biological media is a prerequisite for all types of applications. Depending on the type of application, the proper coating, functionalization and (bio)conjugation of the nanoparticles …

In this doctoral thesis, we present the superhydrophilic effect on surfaces of three different materials, i.e. highly oriented pyrolytic graphite, graphite foil and graphite grain in polymer composite. In order to induce this complicated effect on the surface we used reactive oxygen plasma treatment. The plasma was created in glass …
