KTaO3 belongs to the group of incipient ferroelectrics, which are materials important from the fundamental, as well as from the applications, point of view. It is well known in its single-crystal form; however, the processing of technologically interesting ceramics and thin films is a challenging task and knowledge of their …

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 …

This thesis investigates the use of single liquid-crystal droplets as optical microresonators and lasers. We have shown that liquid-crystal droplets can support a number of different optical modes that can be excited by introducing a fluorescent dye in the liquid crystal material and using an external excitation source of light. …

In this thesis we demonstrate a new, simple, and ecient method for the solid-state synthesis of oxides with a complex chemical composition. We modify the traditional solidstate synthesis method, which is used in the majority of ceramics laboratories around the world, in order to prepare multi-metallic oxide powders from classic …

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 …

We investigate the dynamics in one-dimensional (1D) and two dimensional (2D) mesoscopic superconductors in an external magnetic field using the time-dependent Ginzburg-Landau equations. We analyze the different transitions between metastable states and describe the creation of topological defects that occur as the phase of the Ginzburg-Landau order parameter makes finite …

Polycrystalline, BaTiO3 nanorods and SrTiO3 nanotubes were synthesized by the electrophoretic deposition (EPD) of a barium titanate sol and a strontium titanate sol into 2D ordered anodic aluminium oxide templates (AAO) with a subsequent thermal treatment and template removal. The BaTiO3 nanorods grown within the AAO template membranes had diameters …

Organotin compounds (OTCs) are the organometallic compounds with the most numerous applications. Today, it is more than 50 years of their intensive development and use. While they are highly useful chemicals they are also extremely toxic to a wide array of aquatic and terrestrial living organisms at very low concentrations. …

The presence of insoluble amyloid aggregates in various human tissues correlates with the development of many human disorders (amyloidoses), including neurodegenerative diseases. Deposition of the aggregated misfolded proteins in the brain, where aggregates can be localized extracellularly or intracellularly, is the main characteristic of Alzheimer's, Parkinson's, Huntington's, prion diseases and …

The past fifteen years has seen the rapid development of various wireless communication devices, which operate at microwave or milimeterwave frequencies (mobile phones, wireless local-area networks (LAN), Bluetooth, etc.). At the same time, this progress has stimulated the development of new materials and process technologies, which enable the size reduction …
