Development of silicon carbide based implants with improved biocompatibility and mechanical properties
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 …
Giant energy-conversion effects in soft and solid advanced materials
This thesis presents the results of our experimental work in the field of new advanced materials such as liquid crystal elastomers (LCEs), electrocalorics and magnetoelectrics. In the first part, the conversion of thermal to mechanical energy is addressed in LCEs. The three important, newly discovered, chemical and physical parameters for …
Synthesis and Characterization of Aluminium Foams
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 …
Structural and electrical properties of 0.65PMN-0.35PT thick films on different substrates
A starting powder with the nominal composition 0.65Pb(Mg1/3Nb2/3)O3–0.35PbTiO3 (0.65PMN–0.35PT), which corresponds to the morphotropic phase boundary (MPB) composition, was prepared by mechanochemical activation followed by attritor milling and low-temperature calcination at 700°C. It had a narrow particle size distribution with the median particle size equal to 0.3 μm. From the …
