    Sammanfattning : In Sweden, extensive research is conducted to find alternative sources of energy that should partly replace the electric power production from nuclear power. With the ambition to create a sustainable system for producing energy, the use of renewable energy is expected to grow further and biofuels are expected to account for a significant part of this increase.

  3. 3. Identification and Variation of some Functionality Related Characteristics of Pharmaceutically Relevant Solid Materials and their Effect on Product Performance

    Författare :Frauke Fichtner; Göran Alderborn; Åke Rasmuson; Peter Kleinebudde; Uppsala universitet; []
    Nyckelord :Pharmaceutics; Particle size distribution; Degree of agglomeration; Amorphous lactose; Matrix agglomerates; Drug release; Compactability; Tablet tensile strength; Particle fracture strength; Surfactant; Compression; Galenisk farmaci;

    Sammanfattning : The aim of this thesis was to identify some functionality related characteristics of pharmaceutically relevant solid materials and to study the effect of their variation on processing behaviour and product performance. For this purpose, particles with different characteristics were prepared under a variety of conditions by crystal agglomeration, wet granulation and spray drying. LÄS MER

  4. 4. Spherical Crystallization of Benzoic Acid

    Författare :Jyothi Thati; Åke Rasmuson; Luis Moreno; Eva Blomberg; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Spherical agglomeration; Spherical agglomeration; Benzoic acid; Solubility phase diagram; Physico mechanical properties; Chemical engineering; Kemiteknik;

    Sammanfattning : Spherical agglomerates of benzoic acid crystals have been successfully prepared by drowning-out crystallization in three solvent partial miscible mixtures. Benzoic acid is dissolved in ethanol, bridging liquid is added and this mixture is fed to the agitated crystallizer containing water. LÄS MER

  5. 5. Submicron gas bubbles in water

    Författare :Fredrik Eklund; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES; microbubbles; nanobubbles; ultrafine bubbles; digital holographic microscopy; nanoparticle tracking analysis;

    Sammanfattning : Gas bubbles smaller than 1 micrometre in water, commonly referred to as nanobubbles, is a growing field of research and innovation. Applications range from medical imaging and drug delivery to mining industry and environmental remediation. LÄS MER
