This paper describes the adaptation of the laser-induced fluorescence measurement technique for the investigation of the primary breakup of modern diesel and gasoline direct injection sprays. To investigate the primary breakup, a microscopic technique is required, and with the help of special tracer dyes, a high fluorescence signal can be achieved in the visible range of the electromagnetic spectr

To clarify the role of differential diffusion in highly turbulent premixed flames, a series of turbulent premixed ammonia/hydrogen/air flames were investigated using the NH-PLIF diagnostics. The investigated flames have almost the same laminar burning velocity, SL, but are characterized by different Lewis number, Le, from 0.56 to 1.77. The Karlovitz number, Ka, of these flames ranges from 11 to 10

På grund av den världsomfattande diskussionen rörande ”klimatförändringen” som pågått under de senaste åren, så har försök gjorts för att få människor att ändra sina vanor och för att hitta alternativa energikällor. I dag är det fossila bränslen som dominerar som energikällor men eftersom de ger upphov till höga koldioxidhalter pågår det forskning för att ta fram alternativa bränslen. En grupp av There has been a worldwide debate about “the climate change” over the past years, accompanied with the efforts in finding a more environmental friendly way to live. One area of research is to find replacements for the fossil fuels, which is the major energy source today. The aim of this project is to investigate the atmospheric properties of a new potential group of biofuels, i.e. the group of com

The enrichment of Fe, relative to alpha elements such as O and Mg, represents a potential means to measure the ages of quasi-stellar object (QSO) host galaxies and probe nucleosynthesis in the early universe. QSOs exhibit prominent Fe II features and Mg II 2800 angstrom resonance doublet emission in the ultraviolet. Although chemical evolutionary models predict that the Fe/Mg abundance ratio decre

In the 1990’s there was a lot of discussions in the EU regarding energy and the need for a common EU energy market. Both for the sake of competition, but also in order to provide a stable supply of energy to all EU citizens. The EU began promoting an EU energy market. The first EU legal acts in this area concerned the establishment of an EU energy market and consequently to create competition be

To be able to face the challenges brought on by climate change there is an urgent need to reduce the heavy dependence on fossil fuels. Bio-oil is one such renewable and carbon-neutral replacement that has shown promising potential. A key step in making bio-oil commercially feasible is improvements of the upgrading processes of the bio-oil. One such upgrading process is catalytic hydrodeoxygenation

In Sweden, almost half of the electricity produced comes from hydropower. However, the amount of water in the reservoir catchments is not evenly distributed throughout the year. During the colder months, precipitation usually falls as snow and accumulates into a snowpack. This frozen water is not available to the energy producers until the spring snow melt when as much as 70% of the annual dischar

This thesis describes the design and characterisation of a vacuum ultraviolet scanning photoelectron microscope as well as results from studies of laterally inhomogeneous surfaces. The instrument utilises synchrotron radiation from an undulator at the 550 MeV storage ring at the MAX-laboratory. The beamline is comprised of a plane-grating monochromator with a Kirkpatrick-Baez objective and a graz

Sustainable and low-emission combustion is in need of novel schemes to enhance combustion efficiency and control to meet up with new emission standards and comply with varying quality of renewable fuels. Plasma actuation is a promising candidate to achieve this goal but few detailed experiments have been carried out that target how specific combustion and plasma related species are affected by the

The 2D semiconductors are important players in environmental and energy fields due to their unique catalytic and physical properties defined by their dimensionality. Versatile functionalities on one 2D matrix will enlarge its application scopes but require dedicated engineering paths. In this work, we present a cross-dimensional strategy by decorating 0D Co3O4 onto 2D Co(OH)2 to form a multifuncti

The modification of the electronic properties of CeO2 thin films through Cu doping is a promising approach to enhancing their performance in photoinduced water splitting (WS). In this study, undoped and Cu-doped CeO2 films of 5 nm thickness with 5 and 11% Cu atomic concentrations were characterized under ambient pressure conditions by near-edge X-ray absorption fine structure (NEXAFS) to provide i

Access to electricity is important to meet the Millennium Development Goals (MDGs). The centralized model of large thermal power stations and a central grid is a conventional system to supply electricity to consumers. This centralized model has failed to provide electricity and to achieve the rural electrification objective in developing countries. Un-electrified areas of the developing world are

Due to the human population, urbanization and the standard of living is increasing, the municipal solid waste is increasing in the same pace. While the society overall is getting more environmentally conscious and getting a better insight in the consequences of not managing the waste that is produced in a better way than dumping it on deposits, problems arise and especially in larger cities. Big p

Popular Abstract in Swedish Med snabbare och pålitligare analysresultat finns stora möjligheter till ett ökat utnyttjande av avfallsresurser för produktion av förnybar energi. Resultat från min forskning gör det möjligt att analysera råvaror för biogasproduktion med större säkerhet och med möjligheten att få upp till nio gånger snabbare resultat. Produktion av biogas har under den senaste tiden ö

Maritime transportation is a significant contributor to SOx, NOx and particle matter emissions, and to a lesser extent, of CO2. Recently new regulations are being enforced in special geographical areas to limit the amount of emissions from the ships. This fact, together with the high fuel prices, is driving the marine industry towards the improvement of the energy efficiency of ships. Although mor

Under de senaste åren har efterfrågan på textilier ökat och andelen textilavfall som återvinns är i dagsläget liten vilket har lett till en ökad miljöpåverkan. Det finns därmed ett behov av nya återvinningsprocesser för textilier, där en möjlighet är att de-polymerisera cellulosa-baserade textilier till glukos genom en alkalisk förbehandling, följt av enzymatisk hydrolys. Att integrera textilåtervOver the past years there has been an increased environmental impact due to an increased textile demand. Only a small fraction of waste textiles is recycled today which indicates a requirement for new textile-recycling processes, where one possibility would be to depolymerize cellulose-based textiles into glucose, with an alkaline pretreatment followed by enzymatic hydrolysis. Due to a high energy
