  1. 11. Absorbent Materials from Kraft Pulp

    Författare :Fredrik Wernersson Brodin; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; retention; MFC; oxidation; Absorbent; absorption; TEMPO; freeze drying; disintegration;

    Sammanfattning : SuperAbsorbent Polymers (SAPs) have, since being introduced in the 1980s, become an important constituent in hygiene products, such as disposable diapers. The design of disposable diapers has changed over the years and today thinner products can be produced partly because of the excellent absorption and retention properties of the petrochemical-based SAPs.

  3. 12. Development Towards Sustainable Ironmaking : The IronArc Process

    Författare :Jonas Svantesson; Mikael Ersson; Robert Eriksson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; IronArc; Refractory wear; plasma generator; freeze-lining; Teknisk materialvetenskap; Materials Science and Engineering;

    Sammanfattning : The IronArc process is a novel process for a more sustainable production of liquid pig iron using electricity for heating and hydrocarbons for reduction. This thesis aims to facilitate its use by investigating possible refractory solutions and the gas blowing in the process which is done by a plasma generator. LÄS MER

  4. 13. Development and Evaluation of Preparation Methods for the Analysis of Cell Membranes Using Time-of-Flight Secondary Ion Mass Spectrometry

    Författare :Jakob Malm; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; salt; cryofixation; TOF-SIMS; supported phospholipid bilayer; freeze drying; vacuum; cells; POPC; glutaraldehyde;

    Sammanfattning : The aim of this work was to evaluate and develop methods for preparing dry samples for TOF-SIMS analysis of cell membranes. For correct interpretation of the analysis data, an understanding of the effects that the preparation method has on the morphology and chemical structure of the sample must first be obtained.

  5. 14. Design of solid dosage forms for mucosal vaccination - Investigations on the influence of excipients on product performance

    Författare :Annika Borde; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hydrophilic matrix tablets; osmotic pressure; protein release; freeze-drying; Vibrio cholerae; mucoadhesion; Bradford Assay; sublingual vaccine tablet; mucosal vaccination;

    Sammanfattning : Most vaccines today are liquid formulations for parental administration. However, there are several drawbacks connected to these vaccines. Since injectable vaccines only induce systemic antibody responses, they are not effective against the various pathogens that affect mucosal surfaces with poor permeability for serum-derived antibodies, e.g. LÄS MER

  7. 15. Gluten Protein-Based Microcellular Foams and Composites: Development and Functional Properties

    Författare :Thomas Blomfeldt; Mikael Hedenqvist; Mats K G Johansson; Lars Kloo; KTH; []
    Nyckelord :Wheat Gluten; Foam; Freeze-drying; Glycerol; Bacterial cellulose; Pore structure; Protein structure; Compression; Thermal conductivity; Combustion;

    Sammanfattning : Most common foams are produced from non-renewable resources (e.g., synthetic plastics),with a number of environmental concerns, hence there is a demand for alternative bio-derivedfoam materials. Wheat gluten protein is widely known to have excellent foaming properties(e. LÄS MER
