  1. 16. Charge and proton dynamics in molecules and free clusters : from atomic to nanometer scale

    Författare :Bart Oostenrijk; Synkrotronljusfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Charge transfer; Electron-Ion coincidence; proton hopping; Coulomb explosion; Cluster fission; site-selective dissociation; Molecular photodissociation; spectroscopy; Fysicumarkivet A:2018:Oostenrijk;

    Sammanfattning : The origin of properties in complex systems can often be traced to mechanisms involving charge and energy transfer in only a few embedded molecules. The detailed study of the time evolution of these mechanisms in their original environment is a challenging task. LÄS MER

  2. 17. Downstream Processing Using Membrane Technology

    Författare :Anna Persson; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kemiteknik och kemisk teknologi; Biochemical technology; Chemical technology and engineering; Protein A; Bovine serum albumin; Lactic acid; Electrodialysis; Ultrafiltration; Microfiltration; Downstream processing; Membrane; Biokemisk teknik;

    Sammanfattning : Membrane filtration is a very gentle separation technique and can be used at low temperatures. This makes it suitable for liquids that contain micro-organisms and/or are heat sensitive, which is often the case in liquids processed in the field of biotechnology. LÄS MER

  3. 18. Synthesis of Small Molecules Targeting ADP-Ribosyltransferases and Total Synthesis of Resveratrol Based Natural Products

    Författare :Anders Lindgren; Mikael Elofsson; Nicholas Westwood; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; organic synthesis; quinazolinone; ARTD; PARP; total synthesis; polyphenols; bensofuranes; organisk kemi; Organic Chemistry;

    Sammanfattning : Diphtheria Toxin-like ADP-RibosyltransferasesThe Human ADP-ribosyl transferases (ARTDs) are a group of poorly studied enzymes which are believed to be involved in e.g. DNA repair, protein degradation, transcription regulation and cell death. Medicinal chemistry programmes aimed at developing selective inhibitors of these ARTDs were initiated. LÄS MER

  4. 19. Synthesising colloidal molecules with tunable interactions from soft responsive microgel particles

    Författare :Linda Månsson; NanoLund: Centre for Nanoscience; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; microgels; polymers; colloids; colloidal synthesis; self-assembly; material scaince; confocal microscopy; light scattering; microgels; polymers; colloids; colloidal synthesis; self-assembly; material science; confocal microscopy; light scattering;

    Sammanfattning : Colloidal self-assembly is an attractive bottom-up approach to new superstructures and materials with new properties. However, the typical spherical shape and isotropic interaction potential limit the repertoire of ordered structures that can be obtained from synthetic colloids. LÄS MER

  5. 20. Synthesis of amino- and hydroxyl-substituted bridged bicyclic compounds and their application in asymmetric catalysis

    Författare :Cecilia Olsson; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; organocatalysis; asymmetric catalysis; bicyclo[2.2.1]heptane; bicyclo[2.2.2]octane; dibenzobicyclo[3.3.1]nonane; bioreduction; enzymatic kinetic resolution;

    Sammanfattning : In this work, hydroxyl- and amino-substituted bridged bicyclic compounds based on bicyclo[2.2.1]heptane, bicyclo[2.2. LÄS MER
