2. 1. Mould on building materials - A calorimetric study of fungal activity as a function of environmental factors

   Author : Yujing Li; Avdelningen för Byggnadsmaterial; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; materiallära; byggnadsteknik; building construction; fungal activity; temperature; relative humidity; building; image analysis; indoor environment; wood; materialteknik; material technology; mould; calorimetry; isothermal calorimeter;

   Abstract : Mould problems in buildings have become a growing concern during the past decades. The growth of mould fungi indoors deteriorates air quality, influences human health and causes economical losses. Preventing mould growth from occurring is a more cost effective option than cleaning and renovation of buildings with mould problems. READ MORE

4. 2. 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.

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. Towards More Specific Microcalorimetric Studies With Special Emphasis on Biological Systems

   Author : Peter Johansson; Biokemi och Strukturbiologi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; isothermal heat conduction micro calorimetry spectrophotometry diode array pH oxygen titration chemical reaction biological bacteria perfusion photo carbon dioxide plant enthalpy Gibbs energy kinetic; Biology; Biologi;

   Abstract : A new approach in isothermal heat conduction microcalorimetric studies of chemical and biological processes is explored. The general (non-specific) method of calorimetry is combined with more specific analytical methods of analysis to "multi-functional microcalorimetric process monitors". READ MORE

7. 5. Mechanism-based flow stress model for Ti-6Al-4V : applicable for simulation of additive manufacturing and machining

   Author : Bijish Babu; Lars-Erik Lindgren; Jean-Philippe Ponthot; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material modeling; Ti-6Al-4V; dislocation density; vacancy concentration; additive manufacturing; hot forming; heat treatment; Material Mechanics; Materialmekanik;

   Abstract : Ti-6Al-4V has remarkable properties such as high specific mechanical properties (viz. stiffness, strength, toughness, fatigue resistance), corrosion resistance, biocompatibility etc. These properties make it attractive for applications in aerospace, chemical industry, energy production, surgical implants, etc. READ MORE
