Most of the increase in world electricity demand until 2030 is expected to come from developing countries (IRENA, 2016) and transition to carbon free energy production technologies offers the opportunity to reduce the negative effects of this increase. With majority of the low and middle income countries located in the areas of favourable solar radiation, PV technology is likely to become a key so
The rapid growth of photovoltaic (PV) deployment has raised concerns about the management of end-of-life PV modules, particularly crystalline silicon (c-Si) technologies approaching the end of their service life. Although PV systems contribute to renewable electricity generation, the increasing number of ageing modules poses environmental, technical, and resource-related challenges regarding wheth

Context. The solar mid-infrared metallic emission lines have already been observed and analyzed well, and the formation scenario of the Mg I 12 mu m lines has been known for more than a decade. Detections of stellar emission at 12 mu m have, however, been limited to Mg I in very few objects. Previous modeling attempts have been made only for Procyon and two cool evolved stars, with unsatisfactory
While the impact of H2 chemistry on super adiabatic flame temperature (SAFT) for hydrocarbons is well understood, super adiabaticity for premixed H2 combustion has not been previously reported. In the present work, for the first time, premixed H2/air and H2/N2O combustion in 0D and 1D context have been analysed to show that the instantaneous (0D) or local (1D) temperature exceeds the equilibrium t
India stands in second place as a manufacturer of cement in the world, accounting for over 8 % of the worldwide mounted capacity until the end of the year 2018. It is estimated that the production of the cement will touch 550 Mt by the year 2020 and will reach more than 600 Mt by 2025. Up to the year 2015, the total emissions of CO2 from cement sector in India have touched the level of around 150
Popular Abstract in Swedish Vid framställning av koncentrerade fruktjuicer utsätts produkten för värmebehandling i form av indunstning och pastörisering. Värme-behandlingen försämrar produktens sensoriska kvalitet, dels eftersom aromerna är flyktiga och snabbt avdunstar, och dels eftersom värmen påskyndar kemiska förändringar av aromämnena. Några viktiga fördelar uppnås dock genom tillverkning av During production of concentrated fruit juices, both physical and chemical losses of aroma compounds occur due to heat treatment such as pasteurisation and evaporation. This leads to an inferior quality of the final product. By recovering the aroma complex from fresh juice and then adding it back to the processed juice, heat treatment can be avoided. Hydrophobic pervaporation is an emerging membr
The vast majority of the biofuels presently used in the EU are so called first generation biofuels produced from crops. Concerns of food security, displacement of food crop production and indirect land use change (iLUC) has led to the introduction of measures to reduce the use of first generations biofuels and promote so called advanced biofuels based on feedstock that does not compete with food/f
A mononuclear iron(II) complex [FeII(N4PyMe2)(OTf)](OTf)(1), supported by a new pentadentate ligand, bis(6-methylpyridin-2-yl)-N,N-bis((pyridin-2-yl)methyl)methanamine (N4PyMe2), has been isolated and characterized. Introduction of methyl groups in the 6-position of two pyridine rings makes the N4PyMe2 a weaker field ligand compared to the parent N4Py ligand. Complex 1 is high-spin in the solid st
Manganese superoxide dismutases (MnSODs) are enzymes that convert two molecules of the poisonous superoxide radical into molecular oxygen and hydrogen peroxide. During the reaction, the manganese ion cycles between the Mn(2+) and Mn(3+) oxidation states and accomplishes its enzymatic action in two half-cycles (corresponding to the oxidation and reduction of O(2)(*-)). Despite many experimental and
Attosecond pulses are used to study electron dynamics in atoms and molecules. In this thesis, schemes to control the generation of attosecond pulses and pulse-shaping techniques to compress the pulses are presented. Generation of attosecond pulses requires high intensity, which is reached by focusing a pulsed femtosecond laser. The emitted pulses come isolated or in an attosecond pulse train (APT
Climate warming is expected to alter hydropower generation in California through affecting the annual stream-flow regimes and reducing snowpack. On the other hand, increased temperatures are expected to increase hydropower demand for cooling in warm periods while decreasing demand for heating in winter, subsequently altering the annual hydropower pricing patterns. The resulting variations in hydro
The issue of indirect land use changes (ILUC) caused by the promotion of transport biofuels has attracted considerable attention in recent years. In this paper, we reviewed the current literature on modelling work to estimate emissions of greenhouse gases (GHG) caused by ILUC of biofuels. We also reviewed the development of ILUC policies in the EU. Our review of past modelling work revealed that m
Dye sensitized solar cells (DSSCs) recently attracted much attention as a relatively efficient and inexpensive light-to-electricity energy conversion solution. So far the best performing DSSC devices were produced employing ruthenium (RuII) complexes as the active material, nevertheless limited resources of this metal initiated the research of new alternatives. Iron is one of the most abundant ele
Turbo systems have long been implemented into vehicles to increase the specific power. Increasing the pressure for conventional vehicles decreases the mass of the engine and increases the efficiency. Conventional vehicles do however produce carbon dioxide emissions which have become an increasing issue that needs a solution. One possible solution is the fuel cell utilizing hydrogen as fuel. This r
Context. Terrestrial exoplanets orbiting nearby small cool stars, known as M dwarfs, are well suited for an atmospheric characterisation. Because the intense X-ray and UV (XUV) irradiation from M dwarf host stars is strong, orbiting exoplanets are thought to be unable to retain primordial hydrogen- or helium-dominated atmospheres. However, it is currently unknown whether heavier secondary atmosphe
This report covers the design process of a master thesis project with the aim of developing concepts for diffusers. Diffusers are objects that have the ability of spreading the sound energy evenly in a room. The diffusers were to be suitable for use as interior objects in “ordinary rooms” (schools, hospital wards, and offices). The diffusers should, through their aesthetic expression, attract arch
Interactions between light and matter is one way to study both particles whose small spatial sizes render them irresolvable to our eyes and events where the characteristic time scale is too short for conventional recording and measurement techniques. The advent of free electron lasers allow laser pulses of high intensity and small temporal duration such that ultra-fast dynamics in matter systems a
Lignocellulosic biorefineries are a cornerstone in the transition of our largely fossil-based society to a climate-society using renewable raw materials. In first generation of biorefineries the focus was on starch and sugar-based feedstock which lead to a competition with the food supply. In order to avoid this the second generation of biorefineries focus on lignocellulosic feedstocks such as woo
