  1. 1. Structural and functional studies of L-PGDS and SMPDL3A, enzymes in lipid signaling family

    Författare :Sing Mei Lim; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Enzymes are indispensable in maintaining the biological system. They metabolize complex molecules to supply nutrients, to produce energy, to regulate transcription of gene expression, and to control the concentration of effective signaling molecules in a cell, thus maintaining the homeostasis of biological system.

  3. 2. Stimuli-responsive lipid bilayer mimics for protein, virus and cell recognition

    Författare :Sing Yee Yeung; Malmö universitet; []
    Nyckelord :Lipid bilayers; Adaptable; Self-assembled; Monolayers; Supramolecular chemistry; Cell adhesion; Biocensor;

    Sammanfattning : The most well-studied two-dimensional biomimetic cellular membrane modelsare self-assembled monolayers (SAMs) and supported lipid bilayers (SLBs).The former has the advantage of control over ligand density, homogeneity andorientation, allowing unambiguous interaction studies.

  4. 3. Resident T cells in human skin : functional heterogeneity and clinical implications

    Författare :Stanley Sing Hoi Cheuk; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The skin forms a critical barrier against the external environment and is therefore frequently challenged by infections and subjected to immune-mediated diseases as well as malignancies. The Tissue-Resident Memory T (TRM) cell is a subset of T cells that resides at sites of previous infection in the skin and other epithelial tissues. LÄS MER

  5. 4. Harnessing Mesoporous Spheres - transport studies and biotechnological applications

    Författare :Jovice Boon Sing Ng; Lennart Bergström; Frank Caruso; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mesoporous; spheres; particles; CLSM; TEM; controlled-release; molecular transport; lipid membrane; enzyme; intraparticle; lipase; solid support; Inorganic chemistry; Oorganisk kemi; materialvetenskap; Materials Science;

    Sammanfattning : Applications in controlled release and delivery calls for a good understanding of molecular transport within the carrier material and the dominating release mechanisms. It is clear that a better understanding of hindered transport and diffusion of guest molecules is important when developing new porous materials, e.g. LÄS MER

  7. 5. Fabrication and Characterization of Silicon Carbide Power Bipolar Junction Transistors

    Författare :Hyung-Seok Lee; Carl-Mikael Zetterling; Tat-Sing Chow; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; silicon carbide; power device; BJT; current gain; specific on resistance RSP_ON ; breakdown voltage; forward voltage drop; surface recombination; ohmic contact.; Electrical engineering; electronics and photonics; Elektroteknik; elektronik och fotonik;

    Sammanfattning : Silicon carbide bipolar junction transistors (BJTs) are attractive power switching devices because of the unique material properties of SiC with high breakdown electric field, high thermal conductivity and high saturated drift velocity of electrons. The SiC BJT has potential for very low specific on-resistances and this together with high temperature operation makes it very suitable for applications with high power densities. LÄS MER
