1. Particulate matter analysis from engine outlet in heavy-duty diesel vehicles : A study of soot reactivity, morphology and ash-to-soot ratio from the outlet of 6-cylinder and 8-cylinder diesel engines.
Master-uppsats, KTH/KemiteknikSammanfattning : 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
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 temaSammanfattning : 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
3. X-ray Photoelectron Spectroscopy on Clusters: From Water Clusters to Metal & Metal-Oxide Nanoparticles
Master-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionenSammanfattning : 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
4. Raman spectroscopy for characterization of soot and other carbonaceous materials
Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/FörbränningsfysikSammanfattning : 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
5. Spatiotemporal reconstructions of black carbon, organic matter and heavy metals in coastal records of south-west Sweden
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : This study presents reconstructions of black carbon (BC), including spheroidal and amorphous carbonaceous particles (SCP and ACP), organic matter (OM; total organic carbon, TOC; total nitrogen, TN; total sulfur, TS), and heavy metals (Fe, Zn, Pb, Cu, As and Hg) in coastal sediments off the south-west coast of Sweden. Sediment records from eight stations along a north-south transect off the south-west of Sweden were retrieved. LÄS MER
