  2. 1. Electronic Transport in Polymeric Solar Cells and Transistors

    Author : Lars Mattias Andersson; Olle Inganäs; Nir Tessler; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik;

    Abstract : The main topic of this dissertation is electronic charge transport in polymeric and molecular organic materials and material blends intended for solar cell applications. Charge transport in polymers is a strange beast and carrier mobility is rarely a well-defined number. READ MORE

  4. 2. Colour Calibration of Trichromatic Capturing Devices

    Author : Mattias Andersson; Olle Inganäs; Nir Tessler; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Polymer; fullerene; field-effect transistor; solar cell; electrical transport; mobility; Physics; Fysik;

    Abstract : In a time where there is an increasing demand for easily accessible and up-to-date information, digital printing has become a link between traditional printed media and electronic media. Over the last years, applications such as variable data printing, personalised printing and print on demand have changed the way in which printed matter is produced and handled. READ MORE

  5. 3. Heterocystous cyanobacteria, Dps proteins and H2 production

    Author : Christoph Howe; Karin Stensjö; Felix Howe; Nir Keren; Uppsala universitet; []
    Keywords : H2 production; Cyanobacteria; Dps; ferritin-like proteins; iron; nutrient limitation; oxidative stress; biofilm; photobioreactor; iron homeostasis; H2O2;

    Abstract : To mitigate climate change, CO2-emitting technologies have to be exchanged by renewable alternatives such as H2. H2 can be produced by cyanobacteria, but major efforts to enhance H2 production yields by genetic modifications or optimised cultivation conditions resulted in energetic photo-to-H2 conversion efficiencies of 4.

  6. 4. On the effects of structure and function on protein evolution

    Author : Kristoffer Illergård; Arne Elofsson; Nir Ben-Tal; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; protein; structure; function; evolution; membrane; Biochemistry; Biokemi; Biochemistry; biokemi;

    Abstract : Many proteins can be described as working machines that make sure that everything functions in the cell. Their specific molecular functions are largely dependent on their three-dimensional structures, which in turn are mainly predetermined by their linear sequences of amino acid residues. READ MORE

  7. 5. Process analytical methods for monitoring of the film coating on pharmaceutical pellets and tablets using NIR spectrometry and image analysis

    Author : Martin Andersson; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; PLS; PCA; PAC; NIR; chemometrics; moving samples; information depth; release rate; image analysis; near infrared; process analytical chemistry; thickness; coating; film; tablets; Pellets; granules; Analytical chemistry; Analytisk kemi;

    Abstract : Pharmaceutical tablets and pellets are often covered with a coating. There is a need for methods that enable monitoring of the growth of such films during processing. Such analyses can be performed using process analytical chemical methods based on near infrared (NIR) diffuse reflectance spectrometry. It provides with analyses that take only ca. READ MORE
