  1. 1. Sorption Microcalorimetry: Method Development and Applications

    Author : Natalia Markova; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; lyotropic phase transition; hydrate formation; crystallization; sorption enthalpy; sorption isotherm; water vapor; isothermal heat conduction calorimetry; sorption; Physical chemistry; Fysikalisk kemi;

    Abstract : A double twin isothermal microcalorimeter has been designed and its performance has been tested experimentally. The calorimeter makes it possible to continuously and isothermally scan a solid sample in a broad range of relative vapor pressures at near-equilibrium conditions. READ MORE

  2. 2. Xylan sorption kinetics at industrial conditions

    Author : Espen Ribe; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sorption; Yield; Sorption conditions; Kinetics; Kraft cooking; Hemicellulose; Modelling; Black liquor; Xylan;

    Abstract : The kraft process is the most utilised method for the production of wood based chemical pulp for paper applications. During a kraft cook about half of the wood material is dissoluted into the cooking liquor making the liberation of individual fibres possible. This low yield is a great disadvantage for process economy. READ MORE

  4. 4. 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

  5. 5. Towards the enhanced applicability of cold mix asphalt: : An experimental study focusing on surface free energies and the breaking and coalescence of bitumen emulsions

    Author : Abdullah Khan; Nicole Kringos; Per Redelius; Andreas Loizos; KTH; []
    Keywords : Bitumen; Cold Asphalt Mixtures; Minerals Aggregates; Surface Free Energy; Sorption; Contact Angle; Bitumen Emulsions; Breaking and Coalescence; Emulsifiers; Adhesion Promoters.; Bitumen; kallblandad asfalt; mineraler aggregat; fri ytenergi; sorption; kontaktvinkel; Bitumenemulsioner; brytning och koalescensen; emulgatorer; adhesionsegenskaper; Byggvetenskap; Civil and Architectural Engineering;

    Abstract : The environmental, social and economic sustainability of our infrastructure network is clearly of paramount importance to the road-engineering sector as well to society at large. Sustainable road materials and reduced transport of those materials therefore play a significant role. READ MORE
