  2. 1. Sorption Microcalorimetry: Method Development and Applications

    Author : Natalia Markova; Fysikalisk kemi; []
    Keywords : 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

  4. 2. Experimental studies of sorption and transport of moisture in cement based materials with supplementary cementitious materials

    Author : Mahsa Saeidpour; Avdelningen för Byggnadsmaterial; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cement; Concrete; Moisture transport; Hysteresis; Supplementary cementitious materials; Water vapor sorption; Sorption isotherms; Anomalous sorption;

    Abstract : Most deterioration processes in cement based materials are closely related to moisture sorption and moisture transport properties. Therefore, it is important to study these properties, both theoretically and practically. This work is an experimental investigation in this field. READ MORE

  5. 3. Measurement and Modelling using Surface Complexation of Cation (II to VI) Sorption onto Mineral Oxides

    Author : Anna-Maria Jakobsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; surface complexation; goethite; UO2.sup.2 ; alumina; sorption; Co.sup.2 ; NpO2.sup. ; Pm.sup.3 ; Th.sup.4 ; TiO2;

    Abstract : The aim of this work was to experimentally and theoretically study some surface complexation models and how well these can be applied to a simple system. This is done while keeping in mind the interest in including some type of chemical model in performance assessment calculations for much more complex systems. READ MORE

  6. 4. Effect of hydration on thermodynamic, rheological and structural properties of mucin

    Author : Yana Znamenskaya; Malmö högskola; []
    Keywords : mucous gel; mucus; mucin; PGM; BSM; BSM chitosan multilayers; hydration; water sorption isotherm; relative humidity; water activity; bound water; enthalpy of hydration of biopolymer; glass transition; rheology; phase diagram; fiber-like structure; dumbbell-like structure; sorption calorimetry; DSC; QCM-D; SAXS; AFM;

    Abstract : Mucus, an adherent hydrated layer covering the epithelium, is found in all internal tracts of the body and plays an important role in animal and human life. One of the essential functions of mucus is protection of tissues against dehydration. READ MORE

  7. 5. Displacement Washing in the Sulfate Pulp Mill

    Author : Gunnar Eriksson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; metal ions; Kraft pulp; models; diffusion; filter cakes; sorption; temperature; lignin; fibers; washing; lime mud; chemical recovery; displacement; pulp washing;

    Abstract : Displacement washing is an operation in which it is possible to wash solid-phase particles with a minimum of water. In a sulfate pulp mill, the main application is the pulp washing, but lime mud washing also occurs in the chemical recovery. The washing consumes a great deal of water. READ MORE
