    Sammanfattning : Polysucrose (PS) is a synthetic copolymer of sucrose and epichlorohydrin, which can be produced in a variety of molecular sizes. The aim of the study was to evaluate the functionality of PS 15000, mean mol wt 14700, as a marker for intestinal permeability to macro molecules. LÄS MER

    Sammanfattning : For economical reasons filler particles and less expensive fibre raw materials are more frequently used in papermaking. This influences the mechanical properties of the formed papers in a negative way and it is therefore necessary to add strength-enhancing agents to the papermaking furnish. LÄS MER

  4. 8. Lipase catalysed synthesis of speciality chemicals: technical, economical & environmental aspects

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Green Chemistry; surfactant; biocatalysis; enzymatic; epoxide;

    Sammanfattning : Most people agree that the total ecological impact of society has become more than this planet can endure. This is because we consume our resources (such as oil and water) faster than they can regenerate and because we release more substances into the environment than can be assimilated (e.g. CO2). LÄS MER
