  1. 1. Measurement of Self-Heating of Biomass Pellets using Isothermal Calorimetry

    University dissertation from Karlstad : Karlstads universitet

    Author : Ida Larsson; Karin Granström; Anders Lönnermark; Per Blomqvist; Patrick van Hees; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; isothermal calorimetry; biomass pellets; wood pellets; self-heating; reactivity; screening test; isoterm kalorimetri; pellets; biomassa; självuppvärmning; reaktivitet; screeningtest; Miljö- och energisystem; Environmental and Energy Systems;

    Abstract : Self-heating in storage facilities of biomass pellet can lead to spontaneous combustion. This has resulted in many fires over the years, causing both financial and environmental losses.In order to assess the risk for spontaneous combustion of biomass pellets during storage, it is important to know how prone the fuel is to self-heating, i.e. READ MORE

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

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

    Author : Yujing Li; [2007]
    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

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; calorimetry; differntial scanning; isothermal titration; enthalpy; electrolyte; micelles; self-association; thermal gelling; interaction; alkyltrimethylammonium halides; sodium dodecylsulfate; surfactants; polymers; ethyl hydroxylethyl cellulose; viscosity; phase behavior; self-diffusion NMR; Physics; Fysik; Chemistry; Kemi;

    Abstract : The interactions between uncharged polymers, e.g. ethyl(hydroxylethyl)cellulose (EHEC) and some model polymers, and ionic surfactants in aqueous solution has been studied by using isothermal titration and differential scanning calorimetry. READ MORE

  4. 4. Calorimetric methods for the study of fungi on building materials

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

    Author : Yujing Li; [2004]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fungal growth; fungal activity; ergosterol; humidity; temperature; calorespirometry; oxygen; mätmetoder; röta; svamp; byggmaterial; påväxt; kalorimetri; microcalorimetry; isothermal calorimetry; Fungi; building materials; mould; Serpula lacrymans; rot fungi;

    Abstract : The aim of this project is to study the fungal growth habits on building materials as a function of humidity, temperature and other environmental parameters. The method of calorimetry is used as a way to quantify fungal activity on building materials. READ MORE

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

    University dissertation from Thermochemistry, Chemistry Center, P.O.Box 124, S-221 00 Lund

    Author : Dennis Berling; [1998]
    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.
