  2. 1. Monitoring of the oral anticoagulants apixaban and rivaroxaban to optimize individual safety and efficacy

    Author : Fadiea Al-Aieshy; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The oral anticoagulants apixaban and rivaroxaban are administered at fixed doses without requiring routine monitoring. However, there is a dose and exposure dependency in efficacy and safety, and monitoring the anticoagulants may improve treatment outcomes. READ MORE

  4. 2. NOx Storage and Reduction Catalysts. Reduction with Hydrogen and the Influence of Water and Carbon Dioxide

    Author : Anna Maria Lindholm; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NSR catalyst; Pt Ba Al; H2O; CO2; Pt Al; NOx reduction; H2; NH3 formation; NOx storage; Lean NOx Trap; N2O formation; kinetic modeling; Pt Si;

    Abstract : Environmental concern has increased over the past several years and resulted in stringent emission legislation on NOx, CO, and hydrocarbon emissions from automobile exhausts. Moreover, the demands to improve the fuel efficiency of engines and to lower the CO2 emissions have increased, and a way to meet this is by using lean burn engines which operate with oxygen excess.

    Abstract : High temperature oxidation and corrosion of Ni-based superalloys used for blades in industrial gas turbines was studied using advanced high-resolution electron microscopy methods. Both coated and non-coated alloys were tested. READ MORE

  6. 4. Processing and characterization of thin film field effect gas sensors

    Author : Anna Elisabeth Åbom; Linköpings universitet; []
    Keywords : MISFET; Field effect chemical gas sensors; long-term stability; sputtering; Pt; TiN;

    Abstract : At Applied Physics, Linköping University, the main interest for sensor research has been the focused on MISFET (Metal-Insulator-Semiconductor Field-Effect Transistors) and related devices. The gas sensitivity of MISFET’s was first reported by Lundström et al. in 1975. Today a lot of work is being done in this field. READ MORE

  7. 5. Kinetic Studies of NOx Storage and Reduction Catalysts - Flow Reactor Experiments and Microkinetic Modeling

    Author : Anna Maria Lindholm; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NOx reduction; flow reactor experiments; NOx storage; Pt Ba Al; NSR catalyst; microkinetic modeling; combined NSR and SCR system;

    Abstract : The NOx storage and reduction (NSR) technology is a promising technique to reduce NOx during oxygen excess e.g. in lean burn engine exhaust. A typical NSR catalyst consists of the following components: precious metals, such as platinum, palladium or rhodium, a storage component, usually barium, and a high surface area support, such as γ-alumina.
