This work focuses on a group of diatoms, belonging to the genus Pseudo-nitzschia, which is a globally important phytoplankton genus. Some species of the genus produce the toxin domoic acid, which is responsible for shellfish intoxication known as the amnesic shellfish poisoning (ASP). These diatoms have few morphological features 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 …
Bismuth ferrite, BiFeO3 (BFO), has been recognized as a promising lead-free material for high-temperature piezoelectric applications due to its high Curie temperature of 825 °C. However, the practical use of BFO has been limited in particular by its elevated electrical conductivity. In addition, BFO shows the characteristics of ferroelectric hardening, …
Laser ablation (LA) is a versatile technique that can be used for the elemental analysis of diverse materials as well as for synthesis purposes, i.e. for pulsed laser deposition (PLD) of a wide range of materials. Analysis and synthesis will only be successful if the ablated material can be stoichiometrically …
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 …
The research work presented in this thesis considers the development of new biocompatible surfaces that are able to control the adhesion of specific proteins responsible for the development of neurodegenerative diseases such as Creutzfeldt–Jakob, Alzheimer, Parkinson and Lewis body disease. Our approach was focused on problems prior to the detection …
Aluminium foams are prospective class of cell materials that offer a variety of applications in fields such as lightweight structures or crash-energy management. Due to interesting combination of physical and mechanical properties, such as high stiffness at low density, high impact energy absorption, flame and heat resistance, sound absorption, aluminium …
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 …
The theory behind scanning tunneling microscopy and spectroscopy is presented and the basic manipulation techniques are described. Construction details of a low-temperature scanning tunneling microscope for single atom manipulation experiments are given. Single crystal copper (111) and (211) surfaces are studied. Single atom extraction, followed by lateral manipulation procedures is …
The sillenites Bi12MO20 (M = Si, Ge, Ti, Pb, Mn, B1/2P1/2) have been recognised as promising bulk materials for electronic applications because their dielectric properties (5.5 GHz: ε = 37.4 - 41, τf = -19 – (-84) ppm/K, Q x f = 800 - 8100 and Tsin = 680 - …
