  1. 1. Experimental studies of sorption and transport of moisture in cement based materials with supplementary cementitious materials

    Författare :Mahsa Saeidpour; Avdelningen för Byggnadsmaterial; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cement; Concrete; Moisture transport; Hysteresis; Supplementary cementitious materials; Water vapor sorption; Sorption isotherms; Anomalous sorption;

    Sammanfattning : Most deterioration processes in cement based materials are closely related to moisture sorption and moisture transport properties. Therefore, it is important to study these properties, both theoretically and practically. This work is an experimental investigation in this field. LÄS MER

  3. 2. Molecular-level controls on water and organics intercalation in layered minerals

    Författare :Jerry Lindholm; Michael Holmboe; Jean-Francois Boily; Virginie Marry; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Minerals; Dynamic Vapor Sorption; montmorillonite; XRD; adsorption model; intercalation;

    Sammanfattning : Layered minerals are naturally abundant and often display a large surface area in relation to their weight. For swelling layered minerals, most of this area is contained between the layers in the interlayer space. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER

  5. 4. Xyloglucan-based polymers and nanocomposites – modification, properties and barrier film applications

    Författare :Joby Kochumalayil Jose; Lars Berglund; José M. Kenny; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; xyloglucan; packaging; oxygen barrier; nanocomposites;

    Sammanfattning : Biopolymers from renewable resources are of interest for packaging applications as an alternative to conventional petroleum-based polymers. One of the major application areas for biopolymers is food packaging, where a candidate polymer should meet critical requirements such as mechanical and oxygen barrier performance, also in humid conditions.

  7. 5. Bio-inspired polysaccharide nanocomposites and foams

    Författare :Anna Svagan; Lars Berglund; Mats Stading; KTH; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cellulose; starch; microfibrillated cellulose; biomimetic; nanocomposite; nanocomposite foam; mechanical properties; Biomaterials; Biomaterial;

    Sammanfattning : Today, the majority of materials used for single-use packaging are petroleum-based synthetic polymers. With increased concern about the environmental protection, efforts have been made to develop alternative biodegradable materials from renewable resources. Starch offers an attractive alternative since it is of low cost and abundant. LÄS MER
