  1. 1. System studies of MCFC power plants

    Author : Benny Fillman; Pehr Björnbom; Professor Mats Westermark; Gábor Merényi; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fuel cells; fuel cell systems; system studies; process simulation; molten carbonate; Brennstoffzellen; Brennstoffzellensystem; Systemanalyse; Prozeßsimulation; Bränsleceller; bränslecellssystem; systemstudier; processimulering; smältkarbonatbränslecell; Chemical engineering; Kemiteknik;

    Abstract : Die Brennstoffzelle ist ein elektrochemischer Reaktor und wandelt chemisch gebundene Energie direkt in elektrische Energie um. In der stationären Energieerzeugung ist der Brennstoffzellenstapel selbst nur ein kleiner Bestandteil des vollständigen Systems. READ MORE

  4. 4. Metallic materials in Solid Oxide Fuel Cells: Oxidation and chromium evaporation properties

    Author : Mareddy Reddy; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Interconnect; SOFC; High temperature corrosion; Balance of Plant; Chromium evaporation;

    Abstract : Solid oxide fuel cells (SOFCs) are high-temperature energy conversion devices which have great potential due to their high efficiency, low operating costs and flexibility in using conventional hydrocarbon based fuels. However, system cost, durability and performance stability in long-term operation are barriers to the widespread commercialization of SOFC technology. READ MORE

  5. 5. Healing of endosseous implants with different surface characteristics in grafted and non-grafted bone : clinical and experimental studies

    Author : Måns Jungner; Stefan Lundgren; Malou Hultcrantz; Carina Lundqvist; Peter Nilsson; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Dental implants; surface characteristics; bone graft; maxillary sinus; implant survival; oxidized surface; turned surface; sinus membrane elevation; bone formation; macrophages; osteocalcin; osteopontin; CD68; odontologi; Odontology;

    Abstract : Aims: This study uses radiological and clinical evaluations of the healing of endosseous titanium implants presented with different surface characteristics in the clinical situation (paper I-III) and experimentally to describe the early bone healing in maxillary sinus membrane elevation with and without the use of grafting material (paper IV).Material and methods: In paper I, 136 patients were treated with 394 dental implants – 199 were oxidized titanium implants (Nobel Biocare TiUnite) and 195 were turned titanium surface implants (Nobel Biocare Mark III).
