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

    Författare :Anti Liivat; Joseph Nordgren; Josh Thomas; Daniel Brandell; David Brown; Uppsala universitet; []
    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)

    Författare :Chuanbo Gao; Osamu Terasaki; Anders Palmqvist; Stockholms universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mesoporous silica; anionic surfactant; formation mechanism; structural control; Chemistry; 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

    Författare :Johan Marklund; Produktionsekonomi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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

    Författare :Johanna Bergkvist; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :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

    Författare :Bao-Jian Ding; Funktionell zoologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; 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
