    Author : Patrik Milton Karlsson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Arabidopsis; phosphate transport; thylakoid membrane; root plastid; photosynthesis; leaf size; starch metabolism; homology modeling; site-directed mutagenesis;

    Abstract : Phosphorus is an essential element for all living organisms and is central to the genetics and energetics of life. Inorganic phosphate (Pi) is recurrently involved in protein regulation and signal transduction but also in energy transfer as a component of the ATP-molecule. READ MORE

  4. 7. Surface Science Studies of Metal Oxides Formed by Chemical Vapour Deposition on Silicon

    Author : Patrik Karlsson; Anders Sandell; Håkan Rensmo; Marcus Bäumer; Uppsala universitet; []
    Keywords : Physics; chemical vapour deposition; high-k; metal oxides; silicon; dye-solid interface; metal organic; electron spectroscopy; scanning tunnelling microscopy; Fysik;

    Abstract : For an electronic device well-designed interfaces are critical for the performance. Studies of interfaces down to an atomic level are thus highly motivated both from a fundamental and technological point of view. READ MORE
