  1. 6. Lignin-carbohydrate complexes: Model compounds synthesis

    Författare :Filip Nylander; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Lignin-carbohydrate complex; lignin model compounds; lignocellulose;

    Sammanfattning : In lignocellulose there is a recalcitrant interaction by covalent and non-covalent bonds called the lignin-carbohydrate complex. This interaction has been the subject of studies trying to unveil its chemical structure, to understand the mechanims involved in its formation and to determine its influence on practical applications such as the process of turning biomass into ethanol.

  2. 7. Into the Membrane and Beyond : Improving Membrane Protein Over-Expression in Escherichia coli

    Författare :Mirjam Klepsch; Jan-Willem de Gier; Reinhard Grisshammer; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Escherichia coli; membrane protein over-expression; proteomics; T7 RNA polymerase; peptide transport; strain engineering; Biochemistry; Biokemi; Biophysical chemistry; Biofysikalisk kemi; biokemi; Biochemistry;

    Sammanfattning : Membrane proteins fulfil a wide variety of essential functions in the cell and many are (potential) drug targets. Since their natural abundance is usually very low, most membrane proteins have to be over-expressed for functional and structural studies. LÄS MER

  3. 8. Computational Modeling of the Structure, Function and Dynamics of Biomolecular Systems

    Författare :Yashraj Kulkarni; Shina Kamerlin; Markus Meuwly; Uppsala universitet; []

    Sammanfattning : Proteins are a structurally diverse and functionally versatile class of biomolecules. They perform a variety of life-sustaining biological processes with utmost efficiency. A profound understanding of protein function requires knowledge of its structure. LÄS MER

  4. 9. Novel bioinspired and biohybrid electrode materials for hydrogen production

    Författare :Afridi Zamader; Gustav Berggren; Vincent Artero; Marc Robert; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Device; H2; [FeFe] hydrogenases; inspiration; catalyst; multiwalled carbon nanotubes; life cycle assesments; semisynthetic hydrogenases; Kemi; Chemistry; Biokemi; Biochemistry;

    Sammanfattning : This thesis was accomplished under the scope of eSCALED project administrated by EU MSCA horizon 2020 program, which aimed to develop a device called “artificial leaf” responsible for generating fuels or liquid chemicals (H2 production or CO2 reduction) using solar electrolysis. My objective was to develop a noble metal free, efficient cathode materials for H2 production for the device which yield this thesis. LÄS MER

    Sammanfattning : Today, the demand for speed in drug discovery is constantly increasing, particularly in the iterative processes of hit validation and expansion and lead optimization. Irradiation with microwaves (MWs) has been applied in the area of organic synthesis to accelerate chemical reactions and to facilitate the generation of new chemical entities since 1986. LÄS MER
