  2. 1. Lithium iron phosphates as cathode materials in lithium batteries

    Author : Anna S. Andersson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry; lithium batteries; cathode materials; lithium iron phosphates; magnetic properties; Kemi; Chemistry; Kemi; Inorganic Chemistry; oorganisk kemi;

    Abstract : Iron-based oxides are perhaps the only realistic cathode materials for electric and electric-hybrid vehicle applications. Two types of lithium iron phosphate, LiFePO4 andR-Li3Fe2(PO4)3, have been investigated for use within the lithium/lithium-ion polymer batteryconcept. READ MORE

  4. 2. Vertical Trade

    Author : Anna Andersson; Nationalekonomiska institutionen; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Trade in intermediate inputs; fragmentation; private standards; rules of origin; duration;

    Abstract : This thesis consists of three separate papers. They are all empirical papers that examine how fragmentation of production processes and global value chains have affected international trade patterns. The first paper focuses on how private standards in the increasingly geographically fragmented food sector affect firm-import behaviour. READ MORE

  5. 3. Uncharted Waters : Non-target analysis of disinfection by-products in drinking water

    Author : Anna Andersson; David Bastviken; Henrik Kylin; David Reckhow; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Water treatment technologies; chemical disinfection; FT-ICR MS; bioassays; Vattenreningstekniker; klor; kloramin; FT-ICR MS; effektbaserad analys;

    Abstract : Disinfection by-products (DBPs) are potentially toxic compounds formed when drinking water is treated with disinfectants, such as chlorine or chloramine. A large proportion of the exposure to DBPs is still unknown and the health risks observed through epidemiological studies cannot be explained by DBPs known today. READ MORE

  6. 4. Air-sea exchange of O2 and CO2 : Processes controlling the transfer efficiency

    Author : Andreas Andersson; Anna Rutgersson; Brian Ward; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; air-sea flux; oxygen; transfer velocity; water-side convection; Arctic; UVCN; Meteorology; Meteorologi;

    Abstract : World oceans cover more than 70% of the earth surface and constitutes a major sink of atmospheric CO2. Two of the most important gases in the marine carbon cycling are O2 and CO2 and hence accurate descriptions of the air-sea gas exchange of these gases are crucial. READ MORE

  7. 5. Pharmacological evaluation of the NO/cGMP signalling system

    Author : Anna Asplund Persson; Karl-Erik Andersson; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Platelet activation and inhibition are tightly balanced processes, regulated by various endogenous molecules. In this regard, the endothelium plays a key role in mediating inhibition of platelets by releasing nitric oxide (NO) and cAMP-elevating prostaglandins. READ MORE
