Preparation of nanocrystalline ceramic materials made from zirconia oxide
Vlček, Ondřej ; Prajzler, Vladimír (referee) ; Šťastný, Přemysl (advisor)
Bachelor thesis is focused on preparation of nanocrystalline stabilized zirconia ceramics. The theoretical part is dedicated to zirconia ceramics. Theoretical part describes and unveil the transformation-induced toughening mechanism in partially stabilized zirconia ceramics, the processing routes of these ceramic materials and their utilization. The research part describes preparation of yttria partially stabilized nanocrystalline zirconia ceramics by slip casting method.
Doped ceramic substrates for plasma aplications
Hliničan, Jan ; Šťastná, Eva (referee) ; Šťastný, Přemysl (advisor)
This bachelor thesis summarizes findings on subject: Doped ceramic substrates for plasma aplications. The thesis is divided into two parts. The first part is a literary research focused on topic: production of thin ceramic tapes by tape casting and their use. The second part is experimental. It deals with the preparation of alumina tapes doped with magnesium spinel (MgAl2O4) in different amounts. Phase composition and microstructure will be evaluated on prepared structures. The prepared samples will be used for the production of electrodes for atmospheric plasma discharge.
Multi-phase porous bioceramics bone scaffolds based on calcium phosphates
Smiešková, Jana ; Šťastná, Eva (referee) ; Šťastný, Přemysl (advisor)
This bachelor thesis summarizes findings on subject: Multi-phase porous bioceramics bone scaffolds based on calcium phosphates. The thesis is divided into two parts. The first part is a literary recherche speaking on topic: Tricalcium-phosphate-based bioceramic materials and their interaction with the body of the recipient. The second part is experimental. It describes the preparation of mixed ceramics (mixture of hydroxyapatite (HA) and tricalcium phosphate (TCP)) and evaluation of their microstructure and changes of phase composition.
Machinable bioceramic foams prepared by gelcasting method
Šťastný, Přemysl ; Částková, Klára (referee) ; Trunec, Martin (advisor)
Diploma thesis is focused on development of method for preparation individualized bioscaffolds prepared by milling of HA foam prepared by gel casting method and consolidated via epoxy curing reaction. Diploma thesis continues in bachelor thesis Modern processing methods of porous bioceramics. Literature search is filled in the newest knowledge from the field of bioactivity enhancement of scaffolds. Experimental part of diploma thesis described development of system for individualized scaffold manufacturing from HA suspension preparation, preparation of ceramic blocks used as material for machining to final blocks machining. Pressure strength of foam were evaluated, too. Chosen samples were coated with calcium polyphosphate coating for biological response enhancement. Coated samples were given for in-vivo test to partner university in Beijing under the terms of project FP7-NMP-2013-EU-China: "Bioscaffolds"
