  1. 1. Sorption Microcalorimetry: Method Development and Applications

    University dissertation from Natalia Markova, Chemical Center, Physical Chemistry 1, P.O. Box 124, 221 00 Lund, Sweden

    Author : Natalia Markova; [2001]
    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

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

    University dissertation from Printed in Sweden by Media-Tryck, Lund University

    Author : Mahsa Saeidpour; [2015]
    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

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

    University dissertation from Malmö University, Faculty of Health and Society

    Author : Yana Znamenskaya; Malmö University.; Malmö University.; [2013]
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; TECHNOLOGY; TEKNIKVETENSKAP; PHARMACY; FARMACI; Technology; 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

  4. 4. Redistribution of moisture and ions in cement based materials

    University dissertation from Division of Building Materials, LTH, Lund University

    Author : Magnus Åhs; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Moisture redistribution; ion redistribution; cement based materials; hysteresis; sorption isotherm; scanning;

    Abstract : There were two principal objectives for this thesis. The first was to develop a methodology and evaluation model of moisture redistribution in order to make the future relative humidity in a screeded concrete slab predictable. The second objective was to develop a method to determine the critical humidity for ion transport in concrete. READ MORE

  5. 5. Moisture properties of self-levelling flooring compounds

    University dissertation from Division of Building Materials, LTH, Lund University

    Author : Anders Anderberg; [2004]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fukttransport; secondary emissions; SLC; alkali; self-levelling; moisture transport; diffusion coefficient; självnivellerande golv; flooring screed; fuktegenskaper; flooring compound; sorption isotherm;

    Abstract : Self-levelling flooring compounds (SLC) are used to level substrates (mainly concrete slabs) before applying final floor coverings. Although it is an extensively used product, only limited research has so far been published concerning their moisture properties. READ MORE
