  1. 1. On the Physical Chemistry of Kraft Lignin – Fundamentals and Applications

    University dissertation from Magnus Norgren, Mid Sweden University, SE-851 70 Sundsvall, Sweden

    Author : Magnus Norgren; [2001]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; sodium taurodeoxycholate; bile acid salts; stabilisa-tion; Hofmeister series; fractals; DLCA; RLCA; self-aggregation; colloid; self-diffusion coefficients; DLVO; Poisson-Boltzmann; pKa; dissociation; macromolecule; kraft cooking; lignin; Fysikalisk kemi; Physical chemistry; cryo-TEM; light scattering; 1H PFG NMR;

    Abstract : This thesis describes the physical chemistry of softwood kraft lignin in aqueous alkaline solutions. Both fundamental and applicational aspects are discussed. Kraft lignin originates either from pulp fibres or from black liquor produced by kraft cooking. READ MORE

  2. 2. Modeling colloidal nanoparticles: From growth to deposition

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Joakim Löfgren; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; density functional theory; thermodynamics; nanorods; colloidal nanoparticles; van der Waals; anisotropic; deposition; dispersive interactions; modeling; gold; DLVO;

    Abstract : In recent decades metal nanoparticles (NPs) have been the subject of intense research. The interest stems from the NPs physicochemical properties that can be conveniently tuned through, e.g., their size, shape or composition. READ MORE
