2. 1. Testing large samples of PCM in water calorimeter and PCM used in room applications by night-air cooling

   Author : Rickard Bellander; Ove Söderström; Gudni Jóhannesson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; phase-change material; PCM; water calorimeter; air heat exchanger; durability; thermal properties; heat capacity; Building engineering; Byggnadsteknik;

   Abstract : The latent-heat-storage capacity in Phase-Change Materials can be used for storing or releasing energy within a small temperature interval. Upon the phase transition taking place in a narrow temperature span, the material takes up or releases more energy compared to sensible heat storage. READ MORE

4. 2. Cellulose-fiber-based thermal insulation materials with fungal resistance, improved water resistance and reaction-to-fire properties

   Author : Chao Zheng; Monica Ek; Dongfang Li; Lars Wågberg; Folke Björk; KTH; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biorefinery; birch bark; cellulose; reaction-to-fire properties; fungal resistance; thermal insulation; water resistance; Fiber- och polymervetenskap; Fibre and Polymer Science;

   Abstract : Thermal insulation materials made from natural fibrous materials, such as cellulose fibers, have advantages over others from a sustainability point of view. However, cellulosic materials are generally prone to mold and absorb moisture, and these have negative effects on the insulation properties, the durability of insulation materials, and interior air quality.

5. 3. 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

6. 4. Innovative Water-Resistant Fire-Retardant Wood incorporating Ammonium Phosphate-based salts for Exterior Use Conditions

   Author : Chia-Feng Lin; Olov Karlsson; Dick Sandberg; George Mantanis; Dennis Jones; Bartłomiej Mazela; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träteknik; Wood Science and Engineering;

   Abstract : Wood is a naturally based material and plays an important role as a renewable resource when aiming for a sustainable society. Nevertheless, its inherently combustible property needs to be enhanced to comply with modern construction methods and regulations. READ MORE

7. 5. Microcalorimetric methods for direct measurement of solubility and solvent activity

   Author : Dennis Berling; Biokemi och Strukturbiologi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; enthalpy of solution; solubility; solvent fugacity; solvent activity; Isothermal calorimetry; vapour pressure; Chemistry; Kemi;

   Abstract : New calorimetric methods for direct measurement of solubility and solvent activity are presented. The classical role of calorimetry for measurements of enthalpic parameters is abandoned and the technique is instead used for assessing thermodynamic quantities related to the chemical potential of a substance in a solution.
