  1. 1. Precipitating Amine Absorption Systems for Carbon Capture

    Author : Hanna Karlsson; Institutionen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CO2 capture; Non-aqueous; AMP; Solubility; Heat of absorption;

    Abstract : Carbon capture using amine-based absorption is an established technology for the separation of gaseous CO2. It is used in the upgrading of gaseous fuels, and it has also been suggested that it could play a crucial role in the mitigation of climate change through post-combustion carbon capture and sequestration (CCS), and by creating carbon sinks through bioenergy CCS.

  2. 2. Particularly harmful particles? : a study of airborne particles with a focus on genotoxicity and oxidative stress

    Author : Hanna Karlsson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; particulate matter; particles; genotoxicity; oxidative stress; DNA damage; inflammation; subway; tire-road; wood;

    Abstract : Today it is well established that particulate matter (PM) cause a wide range of health effects. The underlying mechanisms likely include inflammation, oxidative stress and genotoxicity. There is however a lack of knowledge regarding how particles from different sources contribute to these effects. READ MORE

  3. 3. Some aspects on strength properties in paper composed of different pulps

    Author : Hanna Karlsson; Luciano Beghello; Lars Nilsson; Lennart Stolpe; Øyvind Gregersen; Karlstads universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; paper strength; reinforcement; multilayer; stratified; handsheet former; abaca; southern pine; Chemical engineering; Kemiteknik; Chemical Engineering; Kemiteknik;

    Abstract : For papermakers, an understanding of the development of strength properties in the paper is of uttermost importance. Strong papers are desirable both in the traditional paper industry as well as in new fields of application, such as fibre-based packaging and light-weight building material. READ MORE

  4. 4. Strength Properties of Paper produced from Softwood Kraft Pulp : Pulp Mixture, Reinforcement and Sheet Stratification

    Author : Hanna Karlsson; Luciano Beghello; Lars Nilsson; Lennart Stolpe; Öyvind Gregersen; Karlstads universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; paper strength; tensile strength; tearing resistance; folding endurance; fracture toughness; handsheet former; stratify; multilayer; multiply; reinforcement; refining; beating; abaca; glass fibre; polyester; lyocell; softwood; bond strength; Cellulose and paper engineering; Cellulosa- och pappersteknik; Chemical Engineering; Kemiteknik;

    Abstract : For paper producers, an understanding of the development of strength properties in the paper is of uttermost importance. Strong papers are important operators both in the traditional paper industry as well as in new fields of application, such as fibre-based packaging, furniture and light-weight building material.

  5. 5. Biorefinery systems for energy and feed production : greenhouse gas performance and energy balances

    Author : Hanna Karlsson Potter; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; LANTBRUKSVETENSKAPER; ENGINEERING AND TECHNOLOGY; AGRICULTURAL SCIENCES;

    Abstract : The current dependence on fossil fuels is problematic because these are a finite resource and because their combustion causes environmental degradation. Biorefineries produce a variety of valuable products from biomass that can replace products from petroleum refineries. READ MORE
