  1. 21. Mille-feuille Filter : A Non-woven Nano-cellulose Based Virus Removal Filter for Bioprocessing

    Författare :Simon Gustafsson; Albert Mihranyan; Jonas Lindh; Kurt Brorson; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; virus filtration; mille-feuille; downstream; nanocellulose; protein throughput; protein recovery; LRV; MVM; Cladophora; non-woven filter;

    Sammanfattning : Virus removal filters, produced from synthetic surface-modified polymers or regenerated cellulose by phase inversion, are vital to the production of therapeutic proteins such as monoclonal antibodies and plasma proteins. Use of these filters is also one of the most expensive purification steps in the downstream processing of proteins due to high sales price and being limited to a single use. LÄS MER

  3. 22. Functionalization and characterization of surface supported lipid membranes and their application in cell culture

    Författare :Dorota Thid; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cell - surface interaction; supported phospholipid bilayer; IKVAV; DHA; stem progenitor cells; neural cells; surface analytical techniques; QCM-D; surface functionalization; peptide; cell differentiation; cell attachment; membrane; fatty acid;

    Sammanfattning : Phospholipid bilayers supported on a solid surface constitute a versatile, biomimetic platform for a variety of applications, such as biosensing, drug delivery research, cell engineering and as cell membrane mimics in fundamental cell research. Phosphocholine supported lipid bilayers are resistant to cell attachment in a wide range of conditions, and can be functionalized with bioactive signaling molecules to promote specific interactions with cells.

  4. 23. Antimicrobial materials from cellulose using environmentally friendly techniques

    Författare :Anna Ottenhall; Monica Ek; Josefin Illergård; Orlando Rojas; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Antibacterial; antifungal; cellulosic; mold; bacteria; biobased; bio-based; renewable; insulation; packaging; water treatment; water purification; paper filter; paper; membrane; Antibakteriell; fungicid; mögel; antimögel; pappersfilter; vattenrening; membran; papper; bakterier; cellulosa; förpackning; isolering; förnyelsebar; biobaserade; nya material; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : The transition to a more biobased society introduces both new opportunities and new challenges as we replace nonrenewable materials with renewable alternatives. One important challenge will be to control microbial growth on materials, both to protect the materials from biological degradation and to prevent the spread of infections and toxins that can cause illness.

  5. 24. Cubic Cell Membrane Architectures. Taking another look at membrane bound cell spaces

    Författare :Tomas Landh; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Livsmedelsteknik; Food and drink technology; projections; image analysis; periodic cubic surfaces; membrane morphology; cubic membranes; cell ultrastructure;

    Sammanfattning : A systematic study of cell membrane morphologies whose structure is governed by cubic symmetries has been performed. It is suggested that they are described by periodic cubic surfaces for which space filling surface foliations given by truncated Fourier series defined by the space groups is used as structural representations.

  7. 25. Zeolite Membrane Separation at Low Temperature

    Författare :Pengcheng Ye; Linda Sandström; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Technology; Kemisk teknologi;

    Sammanfattning : The energy consumption of separation process accounts for a large part inchemical industry. Membrane processes use much less energy compared to thecurrently used thermally driven processes and could thereby reduce energyconsumption in industry significantly. LÄS MER
