  2. 1. Polyelectrolyte adsorption on oppositely charged surfaces - Conformation and adsorption kinetics

    Author : Lars-Erik Enarsson; Lars Wågberg; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Polyelectrolyte adsorption; adsorption kinetics; adsorption isotherms; conformation; bridging; stagnation point adsorption reflectometry; quartz crystal microgravimetry; polyelectrolyte titration; cationic polyacrylamide; cationic dextran; colloidal silica; silica surfaces; pulp; Chemistry; Kemi;

    Abstract : Denna avhandling presenterar experimentella studier av polyelektrolytadsorption på motsatt laddade ytor, där substrat av både kiseloxid och blekt barrsulfatmassa har använts. Ett huvudsakligt syfte med denna forskning var att karaktärisera konformationen hos adsorberade skikt av katjonisk polyakrylamid (CPAM) i jämförelse med katjonisk dextran (Cdextran) och relatera denna information till inbindningskapaciteten av kolloidal kiselsyra.

  4. 2. Electrodes and Electrokinetic Systems for Biotechnological Applications

    Author : Sara Nilsson; Nathaniel D Robinson; Fredrik Björefors; Bengt Danielsson; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Research in bioelectronics studies biological systems and materials in combination with electronic interfaces for the development of devices, e.g., for medical applications, drug and toxicity tests, and biotechnology in general. Neural implants and pacemakers are examples of products developed from this area of research. READ MORE

  5. 3. Polyelectrolyte Complexes : Their Characterization and use for Modification of Wood Fibre Surfaces

    Author : Linda Gärdlund; Lars Wågberg; Robert Pelton; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cellulose and paper engineering; Cellulosa- och pappersteknik; Cellulosa- och pappersteknik; Chemical engineering;

    Abstract : For economical reasons filler particles and less expensive fibre raw materials are more frequently used in papermaking. This influences the mechanical properties of the formed papers in a negative way and it is therefore necessary to add strength-enhancing agents to the papermaking furnish. READ MORE
