  1. 1. Divisive structures : Two billions years of biofilament evolution

    Författare :Fredrik Hurtig; Ann-Christin Lindås; Lionel Guy; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Evolution; Archaea; Eukaryogenesis; ESCRT-III; Actin; Profilin; Gelsolin; Asgard; TACK; Sulfolobus; Cell division; Cytokinesis; Cytoskeleton; Heimdallarchaeota; Actin-binding protein; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : Our understanding of the functional and regulatory complexity that existed in the eukaryotic progenitor is poor, and investigations have been hindered by our nebulous understanding of where eukaryotes stem from. Recently discovered archaeal lineages with hitherto unseen homology to eukaryotic systems suggest archaea can further our understanding of the eukaryotic cell’s ancestry. LÄS MER

  3. 2. Design of Functional Structures and Measurement Techniques for Electromagnetic Waves

    Författare :Johan Lundgren; Teoretisk elektroteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; functional structures; frequency selective structures; polarization selectivity; metasurface; near-field measurements; antenna measurements; scattering measurement; power density; random media;

    Sammanfattning : Electromagnetic fields exist all around us. Through evolution, nature has developed tools to interact and use these fields, where our eyes are a spectacular example. Humans have a long history of developing structures and objects of their own to alter and interact with these fields. LÄS MER

  4. 3. Applied density functional theory : calculating structures and energies on ribonucleotide reductase and polycyclic aromatic hydrocarbons

    Författare :Kyung-Bin Cho; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

  5. 4. Interactive Textile Structures

    Författare :Lena Berglin; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This thesis explores the area of smart textile and wearable computing. Smart or Interactive Textiles area generic terms for textile materials and products that in some nontrivial sense are self-active. Smart Textiles represents generation of high-tech, functional textile materials and products. An example of that is wearable computing. LÄS MER

  7. 5. Functional PVC Additives : Core-Shell Nanoparticle and Renewable Resource Plasticizers

    Författare :Bo Yin; Minna Hakkarainen; Mikael Skrifvars; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PVC; nanocomposite; nanoparticle; core-shell; plasticizer; renewable resources; isosorbide; glucose;

    Sammanfattning : Several functional poly(vinyl chloride) (PVC) additives were designed: PVC plasticizers made from renewable resources as alternatives to traditional phthalate plasticizers and core-shell nanoparticle-plasticizers with the aim to design an additive that can improve several mechanical properties simultaneously. Monomeric and oligomeric PVC plasticizers based of isosorbide and glucose were synthesized. LÄS MER
