  2. 16. 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

    Author : Staffan Rydefalk; Lars Mattsson; John Gregory; KTH; []
    Keywords : 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;

    Abstract : 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.

  4. 17. Inclusions and/or Particles Engineering for Grain Refining Purposes in Ferritic Fe-20mass%Cr alloys

    Author : Jesper Janis; Pär Jönsson; Keiji Nakajima; Lauri Holappa; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Inclusions; Particles; Grain size; High Cr; Ferritic; Grain refining; Solidification; Pinning effect; Stainless steel; Oxides; Nitrides; Metallurgical process engineering; Metallurgisk processteknik;

    Abstract : Compared to more common used austenitic stainless steels, ferritic stainless steels contain very low amounts of the expensive alloying element Ni. In addition, they have good corrosion properties, but are sometimes suffering from poor weldability and bad mechanical properties. READ MORE

    Abstract : The transportation industry relies heavily on fossil fuels, a dependency that isnot sustainable for the future. The easiest way to change this dynamics is to userenewable fuels, such as biodiesel or hydrotreated vegetable oils, which can be usedas drop-in fuel or blends, without engine modifications. READ MORE
