  1. 21. Exploring the nonlinear rheological behavior and optical properties of cellulose nanocrystal suspensions

    Författare :Sylwia Wojno; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; rheology; self-assembly.; rheo-PLI; nonlinear oscillatory shear; FTRheology; Cellulose nanocrystals;

    Sammanfattning : Cellulose nanocrystals (CNCs), with their versatile properties, offer immense potential in a range of applications, whether used independently or as sustainable reinforcements in polymers. They also find utility as renewable rheology modifiers in industries such as cosmetics, paints, and foods, where precise control over rheological characteristics is crucial for factors like product stability, prevention of splattering, and efficient processing and transportation.

  3. 22. Surface Modification of Cellulose by Covalent Grafting and Physical Adsorption for Biocomposite Applications

    Författare :Carl Bruce; Eva Malmström; Anna Carlmark; Linda Fogelström; Youssef Habibi; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kemi; Chemistry;

    Sammanfattning : There is an increasing interest to replace fossil-based materials with renewable alternatives. Cellulose fibers/nanofibrils (CNF) are sustainable options since they are biobased and biodegradable. In addition, they combine low weight with high strength; making them suitable to, for example, reinforce composites. LÄS MER

  4. 23. Characterization and Modification of Microstructure in Al-Co-Cr-Fe-Ni Eutectic High-Entropy Alloys

    Författare :Adrianna Lozinko; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; eutectic alloys; solidification; orientation relationship; high-entropy alloys; microstructure; EBSD; recrystallization;

    Sammanfattning : The recently emerging high-entropy alloys (HEAs) present a novel alloying strategy, significantly expanding the scope of metal alloy design. HEAs are defined as alloys consisting of at least four principal elements in equi- or near equiatomic ratios, with a possibility of small amounts of alloying elements. LÄS MER

  5. 24. CHRONIC MUSCULOSKELETAL PAIN. Population studies of pain-experience with special focus on the Total Body Pain and aspects of adaptation in a cognitive-behavior psychological frame of reference

    Författare :John Ektor-Andersen; Kliniskt Centrum för Hälsofrämjande Vård; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Skeleton; muscle system; rheumatology locomotion; Skelett; muskelsystem; reumatologi; widespread; vocational dysfunction; sick leave; prediction; psychosocial factors; population study; pain; musculoskeletal; mechanical exposure; epidemiology; Chronic; coping; cognitive-behavioral psychology;

    Sammanfattning : Musculoskeletal pain-related vocational dysfunction is a major public health problem. The solution is beyond the scope of biomedicine, but the problem could well be analyzed in the complementary, cognitive-behavior psychological frame of reference. LÄS MER

  7. 25. Social referencing in infancy

    Författare :Gunilla Stenberg; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; Psykologi; Psychology; Psykologi; Psychology; psykologi;

    Sammanfattning : In a social referencing process, the infant uses interpretative information displayed by another person, often the infant's parent, to help determine how to handle novel events, persons, and objects. The prime aim of Study I was to examine natural infant-mother interaction behaviors in terms of social referencing, when 10-month-old infants encountered a stranger. LÄS MER
