  1. 16. Use of Switchable Carbamate Surfactants for Design of Reversible Colouring of Cotton

    Författare :Anna-Karin Hellström; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; cotton; pigment; textile colouring; de-colouring; switchable surfactant; carbamate;

    Sammanfattning : Circularity of materials is a global need. However, recycling of cotton often requires many steps involving chemical or mechanical treatments. According to the waste hierarchy, reuse is a more environmentally benign approach than recycling, giving extended lifecycles with only limited processing of materials. LÄS MER

  3. 17. Three Dimensional Multiphysics Modeling of Reversible Solid Oxide Electrochemical Cells for Degradation Studies

    Författare :Maria Navasa; Värmeöverföring; []
    Nyckelord :SOCs; SOECs; SOFCs; multiphysics; modeling; three dimensional; transport phenomena; electrochemical reactions; overpotentials; potentials; boundary conditions; validation; experimental data; degradation; carbon deposition; steam; hydrogen; carbon dioxide; carbon monoxide; carbon activity;

    Sammanfattning : Solid oxide electrochemical cells (SOCs) are considered a highly promising technology for providing efficient, sustainable and economic conversion between chemical energy and electrical energy. SOCs can be operated as fuel cells, where electric power is obtained from fossil or non-fossil hydrocarbon fuels depending on the origin or as electrolysis cells, whereby using electrical energy from renewable sources like wind or solar, chemical energy can be stored as fuels.

  4. 18. Studies on mitochondrial adenosine triphosphatase : uncoupler-reversible inhibition of mitochondrial ATPase and related enzymes by metal chelates of bathophenenthroline

    Författare :Christine Carlsson-Skwirut; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The mitochondrial ATPase constitutes the terminal enzyme of oxidative phosphorylation and is, together with similar enzymes present in chloroplasts and bacteria, responsible for the synthesis of ATP from ADP and Pi during electron transport. The enzyme consists of an extrinsic, catalytically active part, called Fl, that is structurally and functionally linked to an intrinsic, proton-translocating device, called Fo. LÄS MER

  5. 19. Modeling Antibody Aggregation in Downstream Processing

    Författare :Frida Ojala; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Antibody; Aggregation; Downstream processing; Size exclusion chromatography; Reversible reaction model; General rate model;

    Sammanfattning : Antibodies are part of the immune system where their purpose is to recognize and neutralize foreign species such as viruses and bacteria, thus preventing and curing infections. The trend of using antibodies in the treatment of, for example, cancer is increasing. LÄS MER
