  2. 1. Studies of water vapor transport and sorption in wood

    Author : Lars Wadsö; Avdelningen för Byggnadsmaterial; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; evaluation; measurements; non-Fickian behavior; absorption; sorption method; transient; unsteady-state; wood; sorption; surface mass transfer coefficient; water vapor; error analysis;

    Abstract : This thesis deals with the evaluation of measurements of water vapor transport and sorption in wood. It mainly concerns measurements of the weight response of a sample after a step change in relative humidity. The thesis consists of an introduction and eight papers. The eight papers have the following contents: 1. READ MORE

    Abstract : The aim of this thesis work was to gain understanding of the interactions between talc mineral and surfaces, liquids and chemicals relevant for industrial applications, such as pulp and paper. Talc is used in the pulp and paper industry as a filler pigment, in control of pitch (lipophilic extractives) deposits and as a coating pigment. READ MORE

  7. 5. Preparation and characterization of an organic-based magnet

    Author : Elin Carlegrim; Mats Fahlman; Svante Svensson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Organic-based magnets; spintronics; photoelectron spectroscopy; near edge x-ray absorption fine structure spectroscopy; chemical vapor deposition; physical vapor deposition; Material physics with surface physics; Materialfysik med ytfysik;

    Abstract : In the growing field of spintronics there is a strong need for development of flexible lightweight semi-conducting magnets. Molecular organic-based magnets are attractive candidates since it is possible to tune their properties by organic chemistry, making them so-called “designer magnets”. READ MORE
