  1. 11. Narrow-pore zeolites and zeolite-like adsorbents for CO2 separation

    Författare :Ocean Cheung; Niklas Hedin; Paul A. Wright; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; CO2 separation; zeolites; phosphates; titanium silicates; ion exchange; flue gas CO2 capture; biogas upgrading; Materials Chemistry; materialkemi;

    Sammanfattning : A range of porous solid adsorbents were synthesised and their ability to separate and capture carbon dioxide (CO2) from gas mixtures was examined. CO2 separation from flue gas – a type of exhaust gas from fossil fuel combustion that consists of CO2 mixed with mainly nitrogen and biogas (consists of CO2 mixed with mainly methane) were explicitly considered.

  3. 12. Influence of Escherichia coli feedstock properties on the performance of primary protein purification

    Författare :Mattias Råvik; Andres Veide; Åsa Emmer; KTH; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Downstream processing; cell surface properties; surface plasmon resonance; contact angle measurements; microelectrophoresis; aqueous two-phase partitioning; filtration; EBA adsorbents; high-pressure homogenisation; Biochemistry; Biokemi;

    Sammanfattning : Abstract The aim of the present study was to increase the understanding of how the cell surface properties affect the performance of unit operations used in primary protein purification. In particular, the purpose was to develop, set up and apply methods for studies of cell surface properties and cell interactions. LÄS MER

  4. 13. Antibody-Fragments: Protein Engineering, Process Development, and their Application as Affinity Ligands

    Författare :Laila Sakhnini; Tillämpad biokemi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Monoclonal Antibodies; Aggregation; Biophysical Characterisation; Process Development; Affinity Adsorbents; Monoclonal Antibodies; Aggregation; Biophysical Characterisation; Process Development; Affinity Adsorbents;

    Sammanfattning : Monoclonal antibody (mAb) fragments have become the formats of choice for both biopharmaceuticals and ligands in analytical and preparative applications. Their smaller size enables additional advantages over full-length mAbs, such as improved tissue penetration, faster blood clearance for diagnostic applications, improved capacity, and enablement of multivalent formatting.

  5. 14. Structuring porous adsorbents and composites for gas separation and odor removal

    Författare :Neda Keshavarzi; Lennart Bergström; Kurosch Rezwan; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Structure; pulsed current processing; zeolite; aluminophosphate; activated carbon; CO2 separation; adsorption; durability; cellulose; film; coating; Materials Chemistry; materialkemi;

    Sammanfattning : Porous zeolite, carbon and aluminophosphate powders have been colloidally assembled and post-processed in the form of monoliths, flexible free standing films and coatings for gas separation and odor removal. Zeolite 13X monoliths with macroporosites up to 50 vol% and a high CO2 uptake were prepared by colloidal processing and sacrificial templating. LÄS MER

  7. 15. Water treatment using cryogel-based adsorbents - Targeting environmental pollutants at low concentrations

    Författare :Linda Önnby; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adsorption; cryogels; nanoparticles; arsenic; cadmium; water treatment; composites;

    Sammanfattning : The lack of safe, clean water is strongly linked to poverty, underdevelopment and poor health. Water is needed not only to sustain life, but to produce food and in industrial processes. Anthropogenic pollution and natural events can jeopardize access to safe water. LÄS MER
