  1. 1. Determination of VOC Emissions from Surface Coatings by Environmental Test Chamber Measurements

    Författare :Alireza Afshari; RISE; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; chamber; surface coating; emission rate; measurement; VOC; concentration;

    Sammanfattning : The emitting properties of different building materials are obtained by measurements in environmental chambers of a few established designs. In order to interpret the results from the measurements and to predict the influence on the indoor environment, it is necessary to have a good understanding of the parameters governing the emission process.

  5. 4. Concentration measurements in single particle microscopy

    Författare :Magnus Röding; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; diffusion; fluorescence microscopy; nanoparticle characterization; number concentration; optical wide-field microscopy; single particle tracking; Smoluchowski process; diffusion;

    Sammanfattning : The topic of this thesis is the introduction of two novel methods for using single particle microscopy as a tool for absolute number concentration measurements of Brownian particles. The key idea of both methods is that in order to estimate number concentration, the size of the (three-dimensional) particle detection region has to be estimated. LÄS MER

  7. 5. Particle Measurements Using Fluctuations in the Regular Transmittance of Light Through a Particle Dispersion : Concentration and Particles size - Theory, Measurement Principles and Applications for Pulp and Paper Production

    Författare :Staffan Rydefalk; Lars Mattsson; John Gregory; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Particle concentration; Particle size; Cylindrical particles; Large particles; Cellulose fibres; Wood pulp fibres; Suspensions; Particle length; Particle length distribution; Particle width; Manufacturing engineering; Produktionsteknik;

    Sammanfattning : The regular transmittance of light or similar radiation through a flowing suspension of particles fluctuates because of the random occurrence of particles in the beam.In the work presented here, a theory for this fluctuating behaviour with the emphasison dispersions of mm-length slender cylindrical particles having circular crosssections is given.
