  1. 1. Cladophora Cellulose-based Separators for Lithium Batteries

    Författare :Ruijun Pan; Leif Nyholm; Maria Strömme; Jonas Lindh; Zhaohui Wang; Martin Winter; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Cellulose; Separator; Paper making; Lithium-ion battery; Lithium-metal battery; Functionalization.; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

    Sammanfattning : The development of lithium-ion batteries (LIBs) has been focused on exploring and improving the electrode materials and electrolytes in the past decades. An indispensable component, the separator, is however not studied as extensively. In general, a separator has two functions, i.e. LÄS MER

  2. 2. Wood-Based Nanocellulose In Lithium Ion Batteries and Electrochemical Coatings

    Författare :Hyeyun Kim; Ann M. Cornell; Davide Beneventi; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; cellulose nanofibers; lithium ion battery; separator; electro-precipitation; hydrogel; Chemical Engineering; Kemiteknik;

    Sammanfattning : Lithium ion batteries contain diverse functional polymeric materials, e.g. binders and separators. Naturally self-assembled wood cellulose can be disintegrated to nanosized particles with a diversity of morphology by top-down processes, adjusting the manufacturing parameters. LÄS MER

  3. 3. Lokala fjärrvärmesystem

    Författare :Lena C. Olsson; Chalmers University of Technology; []
    Nyckelord :district heating; radiator circuit; low radiator flow; local network; pressure separator; jet pump;

    Sammanfattning : The thesis Local district heating systems deals with a new concept for district heating. The district heating system is arranged as one main system and a number of local systems. The production plants and the main distribution lines belong to the main system. LÄS MER

  4. 4. Studies of collective phenomena in neutron deficient nuclei : by means of lifetime measurements, angular correlation measurements and the recoil-decay tagging technique

    Författare :Karin Andgren; Bo Cederwall; Paul Nolan; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; heavy-ion reactions; multi-detector arrays; recoil separator; in-beam gamma-ray spectroscopy; high spin states; lifetime measurements; recoil-decay tagging; nuclear shape; Nuclear physics; Kärnfysik;

    Sammanfattning : The nucleus is a mesoscopic system that retains features from both the quantum and macroscopic worlds. A basic property of a macroscopic body is its shape. Nuclear shapes can be deduced from experimental data as they influence the excitation mode of the nucleus and hence the energies and lifetimes of its excited levels. LÄS MER
