  2. 1. Structural dynamics of ribulose-1,5-bisphosphate carboxylase/oxygenase

    Author : Michiel Van Lun; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) assimilates carbon dioxide (CO2) from air into biomass. Due to its slow turnover, the reaction is a rate-limiting step in photosynthetic carbon fixation. READ MORE

  4. 2. Si-based structures for light emission and detection

    Author : Amir Karim; Göran Hansson; Wei-Xin Ni; Tom Gregorkiewicz; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik;

    Abstract : Efforts to improve the optical performance of the indirect bandgap semiconductor silicon (Si) has been a major subject of research in the field of Si photonics due to the promising applications of Si based light emitters and detectors for optical communication. With that motivation three different Si based material systems were investigated; Si:Er/O layered structures, SiGe quantum dots and SiSn nano structures, all grown using the technique of molecular beam epitaxy (MBE).

  5. 3. Nucleotide-Dependent Processes in the Thylakoid Lumen of Plant Chloroplasts

    Author : Björn Lundin; Cornelia Spetea Wiklund; Zach Adam; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; plant; chloroplast; thylakoid; nucleotide; PSII; PsbO; Biology; Biologi;

    Abstract : Plants, algae and photosynthetic bacteria are able to harvest the sunlight and use its energy to transform water and carbon dioxide to carbohydrate molecules and oxygen, both important to sustain life on Earth. This process is called photosynthesis and is the route by which almost all energy enters the biosphere. READ MORE

  6. 4. Description of spatial and temporal distributions of epiphytic lichens

    Author : Håkan Lättman; Per Milberg; Bengt Gunnar Jonsson; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; centroid; continuity; lichen; movement; range shift; direction; dispersal; ecological continuity; establishment; global change; global warming; habitat availability; håkan lättman; Biology; Biologi;

    Abstract : Lichens are, in most cases, sensitive to anthropogenic factors such as air pollution, global warming, forestry and fragmentation. Two studies are included in this thesis. The first is an evaluation of the importance of old oak for the rare epiphytic lichen Cliostomum corrugatum (Ach.) Fr. READ MORE

  7. 5. Colloidal synthesis of metal oxide nanocrystals and thin films

    Author : Fredrik Söderlind; Per-Olov Käll; Kajsa Uvdal; Mats Johnsson; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; nanoparticles; synthesis; contrast agents; functionalization; thin films; Chemistry; Kemi;

    Abstract : A main driving force behind the recent years’ immense interest in nanoscience and nanotechnology is the possibility of achieving new material properties and functionalities within, e.g., material physics, biomedicine, sensor technology, chemical catalysis, energy storing systems, and so on.
