  1. 1. Stability and sorption capacity of montmorillonite colloids Investigation of size fractional differences and effects of γ-irradiation

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Karin Norrfors; KTH.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; montmorillonite; colloids; size effect; γ-irradiation; sorption; colloid stability; radionuclides; montmorillonit; kolloider; storlekseffekt; γ-bestrålning; sorption; kollodial stabilitet; radionuklider; Kemi; Chemistry;

    Abstract : Bentonite clay is intended to form one of the barriers in most repositories of spent nuclear fuel located in granite. One important function of the bentonite barrier is to retard transport of radionuclides in the event of waste canister failure. Bentonite has a high sorption capacity of cations and its main constituent is montmorillonite. READ MORE

    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

  5. 5. Polymer Mediated Surface Forces

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

    Author : Martin Turesson; Lunds universitet.; Lund University.; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Polyelectrolyte Solutions; Charge Inversion; Monte Carlo Simulations; Depletion Stabilization; Correlation Attraction; Colloid stability;

    Abstract : The issue of controlling the stability between colloidal particles in solution is important, at least for industrial applications, relying on efficient flocculation or stable dispersions. The objective of this thesis is to shed some light on fundamental mechanisms behind the interplay between attractive and repulsive forces, in solutions containing colloids and polymers. READ MORE
