  2. 1. Freeze-Dried Wheat Gluten-Based Foams

    Author : Thomas Blomfeldt; Mikael Hedenqvist; Delcour Jan; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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

  4. 2. Pharmaceutical Nanocomposites : Structure–Mobility–Functionality Relationships in the Amorphous State

    Author : Joel Hellrup; Denny Mahlin; Göran Alderborn; László Fábián; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; amorphous; pharmaceutical composites; solid state; structure; molecular mobility; spray-drying; freeze-drying; moisture sorption; physical stability; compression; Farmaceutisk vetenskap; Pharmaceutical Science;

    Abstract : Amorphous materials are found in pharmaceutical formulations both as excipients and active ingredients. Indeed, these formulations are becoming an essential strategy for incorporating drugs into well-performing solid dosage forms. READ MORE

  5. 3. The influence of ageing on the salt-frost resistance of concrete

    Author : Peter Utgenannt; Avdelningen för Byggnadsmaterial; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materiallära; materialteknik; Building construction; Material technology; freeze thaw testing; hydration; field exposure; carbonation; drying; Byggnadsteknik; ageing; salt-frost resistance; Concrete;

    Abstract : Abstract This thesis presents the results of an investigation of the influence of ageing on the salt-frost resistance of concrete. The ageing mechanisms investigated were hydration, drying and carbonation. READ MORE

  6. 4. Starch Pickering Emulsions : Process and Encapsulation Stability

    Author : Ali Marefati; Institutionen för livsmedelsteknik; []
    Keywords : 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

  7. 5. Absorbent Materials from Kraft Pulp

    Author : Fredrik Wernersson Brodin; Chalmers University of Technology; []
    Keywords : 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.
