  2. 1. Distribution Patterns and Metapopulation Dynamics of Epiphytic Mosses and Lichens

    Author : Tord Snäll; Håkan Rydin; Johan Ehrlén; Christine Ray; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ecology; plant; metapopulation; model; parameterization; connectivity; dispersal; colonization; extinction; epiphytic; bryophyte; lichen; boreal; fragmentation; Ekologi; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi;

    Abstract : This thesis examines the relative importance of local conditions, dispersal and dynamics of the trees on epiphyte distribution patterns and colonization-extinction dynamics. Study species are the mosses Orthotrichum speciosum and O. obtusifolium, and the red-listed Neckera pennata. READ MORE

  4. 2. Nanoscaled Structures in Ruthenium Dioxide Coatings

    Author : Christine Malmgren; Håkan Olin; Joakim Bäckström; Mittuniversitetet; []
    Keywords : Bleaching chemicals; sodium chlorate; ruthenium dioxide; electrodes; crystallites; nanowires; microscopy; diffraction; electrocatalytic area; reduced energy consumption; NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : An essential ingredient in the generation of environmentally compatible pulp bleaching chemicals is sodium chlorate. Chlorate is produced in electrochemical cells, where the electrodes are the key components. In Sweden the so-called DSA !R electrodes with catalytic coatings have been produced for more than 35 years. READ MORE

  5. 3. Xylan biosynthesis and modification : characterisation of a glycosyltransferase and a glycoside hydrolase in hybrid aspen

    Author : Christine Ratke; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Wood is an important renewable material used by humans for a variety of downstream applications. The basic subcellular structure in wood is the cell wall, mainly consisting of the cross-linked polymers cellulose, hemicellulose, and lignin. READ MORE

  6. 4. Structure Determination and Prediction of Zeolites : A Combined Study by Electron Diffraction, Powder X-Ray Diffraction and Database Mining

    Author : Peng Guo; Xiaodong Zou; Christine Kirschhock; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; zeolites; rotation electron diffraction; structure determination; structure prediction; strong reflections approach; Inorganic Chemistry; oorganisk kemi;

    Abstract : Zeolites are crystalline microporous aluminosilicates with well-defined cavities or channels of molecular dimensions. They are widely used for applications such as gas adsorption, gas storage, ion exchange and catalysis. The size of the pore opening allows zeolites to be categorized into small, medium, large and extra-large pore zeolites. READ MORE

  7. 5. Live long and phosphor : synthesis of new 2,1,3-benzothiadiazole based scaffolds and novel organo-Au(I) luminophores

    Author : Mauricio Posada Urrutia; Christine Dyrager; Sascha Ott; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry with specialization in Organic Chemistry; Kemi med inriktning mot organisk kemi;

    Abstract : 2,1,3-Benzothiadiazole (BTD) has arisen as a scaffold of interest to a variety of fields including materials chemistry and medicinal chemistry. It is utilized in the development of light emitting materials, solar-cells, and batteries. READ MORE
