  1. 1. Absorbent Materials from Kraft Pulp

    Author : Fredrik Wernersson Brodin; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; retention; MFC; oxidation; Absorbent; absorption; TEMPO; freeze drying; disintegration;

    Abstract : 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.

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

    University dissertation from Stockholm : KTH

    Author : Thomas Blomfeldt; KTH.; [2010]
    Keywords : Wheat Gluten; Foam; Freeze-drying; Glycerol; Bacterial cellulose; Pore structure; Protein structure; Compression; Thermal conductivity; Combustion;

    Abstract : 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. READ MORE

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

    University dissertation from Stockholm : KTH

    Author : Jakob Malm; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; salt; cryofixation; TOF-SIMS; supported phospholipid bilayer; freeze drying; vacuum; cells; POPC; glutaraldehyde;

    Abstract : 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.

  4. 4. Freeze-Dried Wheat Gluten-Based Foams

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Thomas Blomfeldt; KTH.; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Foams; Wheat gluten; Glutenin; Gliadin; Renewable; Freeze-drying; Pore structure; Baceterial cellulose; Glycerol; Mechanical properties; Thermal conductivity; Combustion properties;

    Abstract : This thesis presents wheat gluten foams as an alternative to the available commercialfoams. Polymeric foams, like all plastics, are mostly made from petroleum, and this isaffecting the environment negatively with the emission of greenhouse gases and generation oflandfills. READ MORE

  5. 5. Starch Pickering Emulsions : Process and Encapsulation Stability

    University dissertation from Department of Food Technology, Lund University

    Author : Ali Marefati; [2018-02-27]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Starch granules; Pickering emulsions; Encapsulation; Freeze-thaw stability; Freeze-drying; In vitro digestion; In vitro intestinal lipolysis;

    Abstract : The emulsion stabilization functionality of surfactants and biopolymers can be replaced by solid particles adsorbed at the interface, where they create a category of emulsions known as Pickering emulsions. Recently, health and environmental concerns have led to new market demand for natural, biodegradable and renewable sources of ingredients. READ MORE
