  1. 1. Sweet stability

    Författare :Kajsa Ahlgren; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; myoglobin; lysozyme; amyloid fibrils; DSC; trehalose; protein denaturation; neutron scattering; glass transition; sucrose;

    Sammanfattning : The disaccharide trehalose is known for its ability to stabilise proteins by preventing aggregation and elevating their denaturation temperature, consequently avoiding unfolding. The folding and function of proteins are vital for many biological processes. LÄS MER

  3. 2. Molecular Mechanisms Influencing the Performance of Amorphous Formulations for Poorly Water-Soluble Drugs

    Författare :Khadijah Edueng; Christel Bergström; Denny Mahlin; Michael Hageman; Uppsala universitet; []
    Nyckelord :Amorphous formulation; crystallisation; supersaturation; glass-forming ability; physical stability; glass stability; spray-dried solid dispersion; dissolution; promiscuous glass former; poorly-soluble drug; solid-to-solid; solution-mediated; particle-associated; Farmaceutisk vetenskap; Pharmaceutical Science;

    Sammanfattning : Crystallisation is a concern for amorphous formulation because it compromises the solubility-enhancing benefit gained from amorphisation. Traditionally, amorphous formulation had been designed primarily based on trial-and-error approach. LÄS MER

  4. 3. Additive manufacturing of fused silica glass

    Författare :Pawel Maniewski; Michael Fokine; Fredrik Laurell; Daniel Milanese; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; laser cladding; 3d printing; additive manufacturing; glass; fused silica; laser; scattering; silica; Optik och fotonik; Optics and Photonics; Teknisk materialvetenskap; Materials Science and Engineering;

    Sammanfattning : Additive Manufacturing, of both metals and polymers, has seen rapid development in recent years, whereas the progress in glass has been rather slow. Today, glass can be considered the last frontier without a specialized 3D printing method available. LÄS MER

  5. 4. Laser processing of Silica based glass

    Författare :Patrik Holmberg; Fredrik Laurell; Valerio Pruneri; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fiber Bragg Gratings; photosensitivity; Glass; laser machining; optical fibers; fiber sensor; Physics; Fysik;

    Sammanfattning : The main topic of this thesis work is photosensitivity and photo-structuring of optical fibers and bulk glass. Although research in the field of photosensitivity in glass and optical fibers has been ongoing for more than three decades, the underlying mechanisms are still not well understood. LÄS MER

  7. 5. Impact of Glass Formation on the Thermal Stability of Non-Fullerene Solar Cells

    Författare :Sandra Hultmark; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; nanostructure.; glass formation; conjugated polymers; kinetic fragility; organic solar cells; Keywords: organic electronics; bulk heterojunction blend; thermal stability;

    Sammanfattning : The world is facing immense challenges such as climate change and the depletion of non-renewable resources, making renewable sources of energy essential for a sustainable future. Organic solar cells are emerging as a promising technology; however, their stability requires significant improvement. LÄS MER
