  2. 16. Innovative Contact Free Sensors for Metallurgical Process Control

    Author : Donald Malmberg; Stuart M. Millman; Högskolan i Halmstad; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; microwave spectroscopy; laser; TDLAS; high temperature; gas; slag; NATURAL SCIENCES; NATURVETENSKAP; spectroscopy; slag analysis; high temperatures; Mät- och instrumenteringsteknik; Instrumentation technology; TDLAS; microwave; laser; Fysicumarkivet A:2003:Malmberg;

    Abstract : The steel- and metal industry has an extensive production processing comprising many different process steps of solid, gaseous and liquid nature. Thus it is obvious that a number of different measurement technologies must be used to collect and evaluate key physical parameters which are necessary to control the production processes. READ MORE

  4. 17. Light Propagation and Gas Absorption Studies in Turbid Media Using Tunable Diode Llaser Techniques

    Author : Liang Mei; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; gas in scattering media absorption spectroscopy; tunable diode laser absorption spectroscopy; frequency modulated light scattering interferometry; light propagation; Absorption spectroscopy; turbid media; diode laser; gas monitoring; porous media; ceramics; food packaging; Fysicumarkivet A:2014:Mei;

    Abstract : Optical absorption spectroscopy is a widely used analytical tool for constituent analysis in many applications. According to the Beer-Lambert law, the transmitted light intensity through a homogeneous medium is an exponential function of the product of the concentration, the total pathlength, and the absorption cross-section of the absorbing substance.

  5. 18. Gas-sensors for Automobile Interiors

    Author : Eva-Lotta Kalman; Haugen John-Erik; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The concentration of pollutants in the car compartment air is influenced not only by neighboring vehicles, but also by pollutants originating from the car's interior trim materials. These pollutants may cause nuisance and even pose a safety risk as some condense on the windscreen and form an oily film that dims the screen. READ MORE

  6. 19. Submicron gas bubbles in water

    Author : Fredrik Eklund; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; microbubbles; nanobubbles; ultrafine bubbles; digital holographic microscopy; nanoparticle tracking analysis;

    Abstract : Gas bubbles smaller than 1 micrometre in water, commonly referred to as nanobubbles, is a growing field of research and innovation. Applications range from medical imaging and drug delivery to mining industry and environmental remediation. READ MORE

  7. 20. Pyrolysis of biomass. Rapid pyrolysis at high temperature. Slow pyrolysis for active carbon preparation

    Author : Rolando Zanzi; KTH; []
    Keywords : rapid pyrolysis; pyrolysis; wood; agricultural residues; biomass; char; tar; gas; char reactivity; gasification; steam; active carbon;

    Abstract : Pyrolysis of biomass consists of heating solid biomass inthe absence of air to produce solid, liquid and gaseous fuels.In the first part of this thesis rapid pyrolysis of wood(birch) and some agricultural residues (olive waste, sugarcanebagasse and wheat straw in untreated and in pelletized form) athigh temperature (800ºC–1000ºC) is studied ina free fall reactor at pilot scale.
