  2. 1. Spark plasma sintered ZrO2-SiO2 glass ceramics and Si3N4 bioceramics

    Author : Le Fu; Wei Xia; Håkan Engqvist; Jérôme Chevalier; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ZrO2-SiO2 glass ceramic; high-strength; translucency; 3D nano-architecture; Si3N4 bioceramic; biodegradable; spark plasma sintering; Materialvetenskap; Materials Science;

    Abstract : This thesis focuses on elaboration and characterization of two types of bioceramics: one is ZrO2-SiO2 nanocrystalline glass ceramic (NCGC) for dental application. The goal is to develop new ZrO2-SiO2 NCGCs with a combination of high strength and high translucency; the other is biodegradable Si3N4 ceramics for spinal fusion. READ MORE

  4. 2. Multifunctional Transition-metal Diboride Coatings Synthesized by Magnetron sputtering with Synchronized Metal-ion Irradiation

    Author : Babak Bakhit; Grzegorz Greczynski; Johanna Rosén; Paul Mayrhofer; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Refractory transition-metal diborides (TMB2), classified as ultra-high temperature ceramics, are promising materials for extreme thermal and chemical environments. There is a growing demand for employing TMB2 in high-temperature electrodes, advanced nuclear fission reactors, molten metal containment, refractory crucibles, thermocouple protection tubes in steel baths and aluminum reduction cells, reinforcement fibers, solar power, aerospace, and armor applications.

  5. 3. Cell-protein-material Interactions on Bioceramics and Model Surfaces

    Author : Åsa Rosengren; Sven Oscarsson; Lucy Di Silvio; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry; protein adsorption; blood proteins; biomaterials; ceramics; glass-ceramics; two-dimensional gel electrophoresis; protein orientation; silicon wafers; atomic force microscopy; bone cell adhesion; divalent cation dependency; Kemi; Chemistry; Kemi;

    Abstract : The objective of this thesis was to investigate and characterize the interaction between blood proteins and different surfaces with emphasis on protein adsorption to bioceramics and model surfaces. Special effort was made to monitor the spontaneous and selective adsorption of proteins from human plasma and to examine the orientation, conformation and functional behavior of single proteins after adsorption.
