Processing and properties of piezo-dielectric ceramic composites
Kučera, Ondřej ; Drdlík, Daniel (referee) ; Maca, Karel (advisor)
The diploma thesis deals with piezoelectric materials combining dielectric and piezoelectric ceramics. The first part of this diploma thesis summarizes the preparation of ceramic materials and thermodynamic of sintering. The electric properties of ceramic materials and current knowledge in BCZT ceramics are summarized. The second part of this diploma thesis describes BCZT ceramics preparation process from raw materials in powder form through the reaction of the precursors to sintering the experimental material into the compact body. The properties of prepared BCZT samples such as density, grain size, hardness, relative permittivity, piezoelectric constant and dielectric loss are summarized in the thesis.
Mechanical and structural properties of collagen nanofribrous layers under simulated body conditions
Říhová, J. ; Suchý, Tomáš ; Vištejnová, L. ; Horný, L. ; Šupová, Monika
The theme of this paper is the analysis of mechanical and structural properties of nanofibrous COL under simulated body conditions and in the presence of osteoblasts and dermal fibroblasts. COL were prepared by electrostatic spinning of 8 wt% collagen type I dispersion with 8 wt% (to COL) of PEG in phosphate buffer/ethanol solution (1/1 vol). The stability of COL was enhanced by means of cross-linking with EDC and NHS at a molar ratio of 4:1. COL were exposed in culture medium for 21 days and human SAOS-2 human dermal fibroblasts and osteoblasts were cultured therein for 21 days as well.
