  1. 1. Ordering in Crystalline Short-Chain Polymer Electrolytes

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Anti Liivat; Uppsala universitet.; [2007]
    Nyckelord :Atomic and molecular physics; polymer electrolytes; molecular dynamics; ionic conductivity; crystalline ordering; polymer chain length; smectic; nematic; Atom- och molekylfysik;

    Sammanfattning : Polymer electrolytes are the most obvious candidates for safe "all-solid" Li-ion batteries and other electrochemical devices. However, they still have relatively poor ionic conductivities, which limits their wider adoption in commercial applications. LÄS MER

  2. 2. Formation mechanism of anionic-surfactant-templated mesoporous silica (AMS)

    Detta är en avhandling från Stockholm : Department of Physical, Inorganic and Structural Chemistry, Stockholm University

    Författare :Chuanbo Gao; Stockholms universitet.; [2009]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mesoporous silica; anionic surfactant; formation mechanism; structural control; MEDICINE Chemistry; MEDICIN Kemi; Structural Chemistry; strukturkemi;

    Sammanfattning : This dissertation is focused on synthesis, characterization and formation mechanism of anionic-surfactant-templated mesoporous silica (AMS). Structural control mechanisms of AMS are investigated. LÄS MER

  3. 3. Supply Chain Inventory Control-Methods for Coordination and Evaluation

    Detta är en avhandling från Stockholm : Department of Physical, Inorganic and Structural Chemistry, Stockholm University

    Författare :Johan Marklund; Lund University.; Lunds universitet.; [1999]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Supply Chain; Inventory; Multi-Echelon; Stochastic; Decentralization; Centralized Control; Distribution; Divergent; Batch Ordering.;

    Sammanfattning : Thanks to the fierce competition and the globalization of markets as well as compa¬nies, supply chain management has emerged as one of the most urgent manage¬rial issues in business today. This thesis is devoted to one aspect of this vast problem area - the coordinated management/control of supply chain inventories. LÄS MER

  4. 4. Grazer-induced responses in marine phytoplankton

    Detta är en avhandling från Stockholm : Department of Physical, Inorganic and Structural Chemistry, Stockholm University

    Författare :Johanna Bergkvist; Göteborgs universitet.; Gothenburg University.; [2012]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; phytoplankton; defence; dinoflagellate; diatoms; paralytic shellfish toxins; polyunsaturated aldehydes; chain formation;

    Sammanfattning : Phytoplankton are the most important primary producers in the world’s oceans, yet little is known of how they avoid the constant threats from the pelagic grazers. From land it is well known that plants defend themselves by having thorns or producing compounds unpalatable to grazers. LÄS MER

  5. 5. On the way of making plants smell like moths - a synthetic biology approach

    Detta är en avhandling från Lund University, Faculty of Science, Department of Biology

    Författare :Bao-Jian Ding; Lund University.; Lunds universitet.; [2014]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; moth pheromone; transcriptome; fatty acyl desaturase; fatty acyl reductase; acetyltransferase; chain shortening; chain elongation; heterologous expression; synthetic biology; plant expression;

    Sammanfattning : Moth caterpillars are major agricultural pests in many parts of the world. In general female moths attract male mates with their pheromone over long distance. Most of the described moth pheromones belong to the same class of chemical compounds, fatty acid derivatives that are produced de novo in the pheromone gland. LÄS MER
