  1. 11. Through air drying : The influence of formation and pulp type on non-uniform drying and air flow

    Författare :Aron Tysén; Christophe Barbier; Lars Nilsson; Hannes Vomhoff; Stig Stenström; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drying; Dewatering; Water removal; Moisture; Non-uniformity; Variability; Tissue; TAD; Through air drying; Thermography; Formation; Pulp; Chemical Engineering; Kemiteknik;

    Sammanfattning : The removal of water is an integral part of tissue paper production. Through air drying (TAD) is used for water removal when producing premium tissue grade products, however, at the price of higher energy demand. A better understanding of TAD may therefore lower the energy demand. LÄS MER

  4. 14. Artificial Water Splitting: Ruthenium Complexes for Water Oxidation

    Författare :Lele Duan; Licheng Sun; Matthias Beller; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; water oxidation; ruthenium; electrochemistry; DFT calculation; photoelectrochemistry; negatively charged ligand; catalyst;

    Sammanfattning : This thesis concerns the development and study of Ru-based water oxidation catalysts (WOCs) which are the essential components for solar energy conversion to fuels. The first chapter gives a general introduction about the field of homogenous water oxidation catalysis, including the catalytic mechanisms and the catalytic activities of some selected WOCs as well as the concerns of catalyst design.
