  3. 2. Photoemission from Alkali Metal Overlayers: Quantum Wells, Photoelectron Interference and Atomic Structure Changes

    Författare :Dan Claesson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; quantum well states; surface structure; alkali metals; angle resolved photoemission; surface electronic phenomena; thin films; collective excitations; electronic structure;

    Sammanfattning : Angle resolved photoelectron spectroscopy is used to investigate alkali metal overlayers on noble metal surfaces. The work deals with interference in photoemission, bulk electronic structure and adsorption induced changes of atomic structure, respectively. The relative importance of surface and bulk in photoemission has remained largely unexplored. LÄS MER

  4. 3. VEGFR-2 in Endothelial Differentiation and Vascular Organization

    Författare :Dan Edholm; Lena Claesson-Welsh; Xiujuan Li; Victoria Bautch; Uppsala universitet; []
    Nyckelord :Molecular medicine; Embryonic stem; VEGFR-2; Flk1; KDR; VEGF; vasculogenesis; angiogenesis; embryoid body; Molekylärmedicin;

    Sammanfattning : The cardiovascular system is the first functional organ to develop during embryogenesis. As the embryo reaches above a certain size, passive diffusion of gases and nutrients is no longer compatible with efficient growth. LÄS MER
