2. 1. Catalytic Incineration of CO and VOC Emissions over Supported Metal Oxide Catalysts

   Author : Per-Olof Larsson; Tillämpad biokemi; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Titania; Ceria; Manganese oxide; Copper oxide; VOC; CO; Ethanol; Ethyl acetate; Metal oxide catalysts; Catalytic combustion; Catalytic incineration; Alumina.; Chemical technology and engineering; Kemiteknik och kemisk teknologi; Fysicumarkivet A:1999:Larsson;

   Abstract : Catalytic incineration is one of the methods to reduce the emissions of CO and VOCs. Low operation temperature and low catalyst cost are essential parameters for catalytic incinerators. Pt/Al2O3 catalysts are frequently used today, but the cheaper metal oxide catalysts can be very competitive if comparable overall activity is obtained. READ MORE

4. 2. CVD and ALD in the Bi-Ti-O system

   Author : Mikael Schuisky; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Halide-CVD; ALD; Bismuth titanate; Bi4Ti3O12; Titanium oxide; TiO2; Bismuthoxide; Bi2O2.33; Epitaxy; QCM.; Kemi; Chemistry; Kemi; Inorganic Chemistry; oorganisk kemi;

   Abstract : Bismuth titanate Bi4Ti3O12, is one of the bismuth based layered ferroelectric materials that is a candidate for replacing the lead based ferroelectric materials in for instance non-volatile ferroelectric random access memories (FRAM). This is due to the fact that the bismuth based ferroelectrics consists of pseudo perovskite units sandwiched in between bismuth oxide layers, which gives them a better fatigue nature. READ MORE

5. 3. Investigation of Nickel- and Iron-Based Oxygen Carriers for Chemical-Looping Combustion

   Author : Erik Jerndal; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Carbon Dioxide Capture; Nickel Oxide; Fluidized Bed; Iron Oxide; Oxygen Carrier; Chemical-Looping Combustion; Ilmenite;

   Abstract : Carbon capture and storage has the potential of reducing emissions of CO2, generated by combustion of fossil fuels. Chemical-looping combustion is a method intended to capture CO2 without an energy consuming gas separation process. READ MORE

6. 4. Electronic Properties of Metal Oxide Films Studied by Core Level Spectroscopy

   Author : Jan Hinnerk Richter; Anders Sandell; Håkan Rensmo; Anne Borg; Uppsala universitet; []
   Keywords : Physics; electron spectroscopy; metal oxide; chemical vapour deposition; ion insertion; metal organic; band alignment; zirconium; titanium; silicon; high k; Fysik;

   Abstract : In this dissertation core level electron spectroscopy has been employed to study various aspects of metal oxide films grown under ultra-high vacuum conditions. Studies on in situ ion insertion of lithium into thin TiO2 systems were performed. READ MORE

7. 5. Crystal chemistry of Fe-Ti oxides in mafic rocks and metabasites: A study aimed at refinement of geological tools and interpretations

   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fe-Ti oxide; hercynite; siderite; stilpnomelane; olivine corona; Swedish Caledonides; hysteresis; PIXE; synchrotron XRD; Rietveld; microprobe; red corundum; palaeomagnetism; eclogite; plagioclase clouding; dolerite; pyroxene gneiss; Geology; physical geography; Geologi; fysisk geografi;

   Abstract : This thesis consists of four subprojects: (A) ‘Clouding of plagioclase by Fe-Ti oxides’, (B) ‘Fe-Ti oxides during high-pressure metamorphism of mafic rocks’, (C) ‘Magnetic study of Fe-Ti oxides in mafic rocks and metabasites’, and (D) ‘Topotactic phase transitions in oxide minerals’. A) In southern Sweden dolerite dikes and gabbros with clouded plagioclase are common. READ MORE
