    Sammanfattning : De ökande luftföroreningarna i Europa är ett allvarligt miljöproblem, och vägtransporterna är en av de största orsakerna till detta. För att ta itu med detta problem och uppfylla nya utsläppskrav måste efterbehandlingssystemen för avgaser förbättras. LÄS MER

  3. 2. Borne in Fire - A Study of Black Carbon Emitted from Coal Fired Power Plants in West Bengal, India.

    Master-uppsats, Linköpings universitet/Institutionen för tema

    Författare :Ra'eesah Hendricks; [2023]
    Nyckelord :Black Carbon; Chemothermal Optical Method; Health Impacts; Particulate Matter 2.5; Thermal Optical Reflectance Method;

    Sammanfattning : Black carbon has been reported to have major impacts on climate, environmental quality, and health. A chemothermal oxidation method, ordinarily used to isolate black carbon from soils, sediments and aquatic samples was applied to explore atmospheric samples. LÄS MER

  4. 3. X-ray Photoelectron Spectroscopy on Clusters: From Water Clusters to Metal & Metal-Oxide Nanoparticles

    Master-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Författare :Emmanouil Tzomos; [2021]
    Nyckelord :Nanoscience; Nanoparticles; Clusters; Synchrotron Radiation; Water Particles; Silver Particles; Silver Oxides; Ethylene Epoxidation; Radiotherapy; PES; XPS; Lund University; FlexPES; MAX IV; Physics and Astronomy;

    Sammanfattning : In the present work, two experimental setups aimed at the production of (1) water clusters and (2) metal-oxide nanoparticles were assembled and commissioned. The experiments on the cluster/nanoparticle beams were set up and performed at the FlexPES beamline of the MAX-IV synchrotron facility. LÄS MER

  5. 4. Defining Black: Characterization of Soot Reactivity with Thermogravimetrical Methods : Definiera svart: Karaktärisering av sotreaktivitet med termogravimetriska metoder

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Adarsh Roy Choudhury; [2020]
    Nyckelord :Diesel Particulate Filter; Chemical Kinetics;

    Sammanfattning : Exhaust emissions in a vehicle has to flow through an exhaust aftertreatment in a diesel vehicle. In a diesel engine, the exhaust emissions are treated with Diesel Oxidation Catalyst (DOC), Diesel Particulate Filter (DPF), and Selective Catalytic Reduction (SCR). Every engine produces a different kind of soot depending on the drive cycle. LÄS MER

  7. 5. Raman spectroscopy for characterization of soot and other carbonaceous materials

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

    Författare :Jonatan Henriksson; [2019]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : 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. LÄS MER
