  1. 1. Influence of Fluid Shear on Primary  Nucleation of Organic Compounds in Solution  Jin Liu  Doctoral Thesis

    Författare :Jin Liu; Åke Rasmuson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Agitation; Primary nucleation; Induction time; Fluid shear; Energy dissipation; Mass transfer; Molecular alignment; Cluster coalescence; Butyl paraben; Curcumin; m-Hydroxybenzoic acid; Solid-liquid interfacial energy; Nuclei critical radius.; Chemical Engineering; Kemiteknik;

    Sammanfattning : In this work, three experimental systems have been used to study the influence of agitation/ fluid shear on primary nucleation. Three organic compounds have been used with different solvents, i.e. butyl paraben in ethanol solution, curcumin in ethanol solution and m-hydroxybenzoic acid in 1-propanol solution. LÄS MER

  3. 2. Structure Evolution during Phase Separation and Gelation of Biopolymer Mixtures

    Författare :Niklas Lorén; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; microstructure; gelatin maltodextrin; biopolymer mixtures; structure evolution; phase separation; stereology; confocal laser scanning microscopy; image analysis; spinodal decomposition; transmission electron microscopy; gelation;

    Sammanfattning : This thesis focuses on the kinetics of phase separation and gelation in aqueous mixtures of gelatin and maltodextrin. The structure evolution of these mixtures at different length scales was recorded by confocal laser scanning microscopy (CLSM) and transmission electron microscopy (TEM). The microstructure was quantified by image analysis. LÄS MER
