  1. 16. Catching Ash : Methodology for ash accumulation in diesel particulate filters

    University essay from KTH/Materialvetenskap

    Author : Charis Pavlou; [2019]
    Keywords : diesel engine; diesel particulate filter; particulate matter; testing rig; accelerating ash accumulation;

    Abstract : The diesel particulate filter captures particulate matter that is produced in the diesel engine. A small fraction of particulate matter is comprised by ash forming matter. When the combustible fraction of particulate matter is removed from the filter, the ash, which is incombustible, remains. READ MORE

  3. 17. Raman spectroscopy for characterization of soot and other carbonaceous materials

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

    Author : Jonatan Henriksson; [2019]
    Keywords : Physics and Astronomy;

    Abstract : Raman spectroscopy is well known as a method that can be used to study the structural characteristics of carbon materials such as soot and carbon black. In this work, a Raman spectroscopy setup was used to record spectra of various carbonaceous samples under different experimental conditions. READ MORE

  4. 18. Carbonaceous aerosols and trace metal deposition in high-latitude snow : a comparative study in Sweden and Alaska

    University essay from SLU/Dept. of Soil and Environment

    Author : Anika Pinzner; [2019]
    Keywords : PM; carbon particles; pXRF; arctic; subarctic; EC OC; LAHM; PSAP; TOT; ICP-MS; filter; contamination; albedo;

    Abstract : This study investigates the advantages and disadvantages of several destructive and non-destructive analytical methods that can be employed to characterize airborne par-ticulate matter (PM) deposited in seasonal snow. To this end, a comparative study was conducted on PM obtained from snowpack surveys in two Arctic/subarctic regions of Northern Sweden and Interior Alaska, USA. READ MORE

  5. 19. Towards omnimaterial printing : Expanding the material palette of acoustophoretic printing

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Jacob Kjellman; [2019]
    Keywords : Acoustophoretic printing; Drop on Demand; Superamphiphobic nozzle; Surface functionalization; Coating; Candle soot template;

    Abstract : Dropp-genereringstekniker är viktiga för industrier som läkemedelsindustrin, livsmedelsindustrin, kosmetikindustrin etc. Traditionella droppgenereringstekniker är dock begränsade i mängden av material som kan processas till droppform. READ MORE

  6. 20. Characterizing particulate carbon using dielectric property measurements

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Madeleine Syk; Joakim Vollmer; [2018]
    Keywords : black carbon; elemental carbon; carbonaceous aerosols; soot; fullerene C60; multiwalled carbon nanotubes; mesoporous carbon; impedance; dielectric; snow melting; capacitance; waveguide;

    Abstract : Interest in effects of carbonaceous particles in the atmosphere has recently taken an upswing due to knowledge of how these particles affect our environment. Carbonaceous aerosols are characterized by their dark color, giving them the ability to absorb both incoming and outgoing radiation of all wavelengths in the atmosphere. READ MORE
