  1. 16. Hot-wall MOCVD of N-polar group-III nitride materials and high electron mobility transistor structures

    Författare :Hengfang Zhang; Vanya Darakchieva; Jr-Tai Chen; Ingemar Persson; Fatemeh (Shadi) Shahedipour-Sandvik; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nitrogen-polar; MOCVD; III-nitride; GaN; AlN; C-face SiC; HEMTs;

    Sammanfattning : Group III-Nitride semiconductors: indium nitride (InN), gallium nitride (GaN), aluminum nitride (AlN) and their alloys continue to attract significant scientific interest due to their unique properties and diverse applications in photonic and electronic applications. Group-III nitrides have direct bandgaps which cover the entire spectral range from the infrared (InN) to the ultraviolet (GaN) and to the deep ultraviolet (AlN). LÄS MER

  2. 17. Getting in and out of shape : relevance for organ formation and cancer

    Författare :Mahdi Mojallal; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : A central question during development is how single cells form functional multi-cellular organ structures. The high reproducibility indicates intricate synchronization of cellular behaviors such as migration, proliferation and cell shape changes. LÄS MER

  4. 19. Shape Matters : Characterization of Weak Interactions and Macrocycles by Conformational Analysis

    Författare :Stefan Peintner; Máté Erdélyi; Oliver Zerbe; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : When studying conformational ensembles, it is most challenging to identify and characterize rapidly interconverting individual conformers. A precise description of the structural dynamics, however, rewards viable knowledge on conformation stabilizing forces as well as on the impact of external influences on the conformer composition.

  5. 20. To unite or disconnect : AmotL2 in tubulogenesis and tumor invasion

    Författare :Sara Hultin; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : For an epithelial- or endothelial cell sheet or ‐tissue to form, individual cells must come together unite and connect. Contacts to adjacent cells and underlying matrix must be initiated, and the junctional proteins mediating the contacts must be further linked to intracellular cytoskeletal networks. LÄS MER
