  2. 1. Oxidation of Kraft Pulp Fibres - Hydrogen Peroxide Oxidation under Acidic Conditions and its Influence on the Properties of Pulp

    Author : Axel Martinsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : An increase in the use of bio-based products, combined with a decrease in the use of fossil-based products, is important for fulfilling the demands of a growing population in a sustainable manner. Moreover, reducing the usage of single-use plastics is vital in combating the plastic pollution that is afflicting our environment. READ MORE

  4. 2. On the Interrelation Between Kraft Cooking Conditions and Pulp Composition

    Author : Catrin Gustavsson; Mikael E. Lindström; Jorge Colodette; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Delignification; Kraft pulping; Residual phase lignin; Hydroxide; Hydrogen sulphide ion; Ionic strength; Temperature; Bleachability; Hexenuronic acid; Carbohydrates; Cellulose and paper engineering; Cellulosa- och pappersteknik;

    Abstract : In the early 1990’s, a lot of work was focused on extending the kraft cook to a low lignin content (low kappa number). The driving force was the need to further reduce the environmental impact of the bleaching, as less delignification work would be needed there. READ MORE

  5. 3. Uncertainty in Endodontics : Strategies for Understanding and Management

    Author : Joséphine Brodén; Helena Fransson; Maria Pigg; Thomas Davidson; Sivakami Rethnam Haug; Malmö universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; endodontology; uncertainty; cost-effectiveness; dental education; vital pulp treatment;

    Abstract : Dentists often experience uncertainty when deciding on the most effective treatment for a particular patient. There are various sources of uncertainty and different strategies for coping with it, such as reducing or accepting it and learning how to make decisions despite feeling uncertain. READ MORE

  6. 4. Chemical Methods for Improving the Fracture Toughness of Paper

    Author : Andrew T. Horvath; Lars Wågberg; Theo van de Ven; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; chemistry; physical chemistry; Cellulose and paper engineering; Cellulosa- och pappersteknik;

    Abstract : Paper is a network material composed of a great number of fibers that interact with each other through fiber joints. In order to make a clear statement regarding observed changes being made in paper, it is vital to determine the structural level of paper that is being affected by chemical modifications. READ MORE

  7. 5. Impact of paperboard deformation and damage mechanisms on packaging performance

    Author : Gustav Marin; Sören Östlund; Mikael Nygårds; Tomasz Garbowski; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solid Mechanics; Hållfasthetslära;

    Abstract : Paper-based materials, such as paperboard, are commonly used as packaging materials. In addition to the fact that paper is renewable, there are also many other benefits of paperboard. READ MORE
