Hydrogen fueled and electrical powertrains are seen as the primary pathways for future sustainable road transport. In our research we focus on hydrogen internal combustion engines. Hydrogen engines offer high efficiency, and the use of hydrogen as fuel means that emissions associated with carbon atoms do not occur. This means that hydrogen engines do not produce carbon monoxide, carbon dioxide, hy

There exists a demand for production of metal nanoparticles for today's emerging nanotechnology. Aerosol-generated metal nanoparticles can oxidize during particle formation due to impurities in the carrier gas. One method to produce unoxidized metal nanoparticles is to first generate metal oxides and then reduce them during sintering. Here, we propose to instead prevent oxidation by introducing th

In recent years, climate change and the corresponding expected extreme weather conditions have been widelyrecognized as potential problems. The construction industry is taking various actions to achieve sustainabledevelopment, implement energy conservation strategies, and provide climate change mitigation. In addition tomitigation, it is crucial to adapt to climate change, and to investigate the p

Key research area Negative emission technologies, or large scale carbon dioxide removal, are by many assessments, policy makers, industries and companies, seen as key to slow or halt climate change. Researchers at LUCSUS studies the narratives, implementation and impacts of these technologies from political, economical and justice perspectives. The research takes a critical perspective, and studie

The paper is concerned with estimation of heat and power consumption in a conceptual plant to produce hydrogen from sucrose-containing or starchy biomass by fermentation. A hydrogen plant connected with a sugar factory is regarded as the basic option; the sugar factory serves as a source of sucrose-containing thick juice for the hydrogen plant, where this feedstock is processed to hydrogen. As ano

Using beam-foil spectroscopy, we have observed several new lines in the B IV and B V spectra. This experimental work was combined with theoretical calculations using ab initio and semi-empirical techniques. We have also critically evaluated all previous and recent experimental and theoretical data for these spectra. Complete data on wavelengths and energy levels based on this analysis are tabulate

The role of inorganic pyrophosphate (PPi) as an energy carrier in the central metabolism of the extremely thermophilic bacterium Caldicellulosiruptor saccharolyticus was investigated. In agreement with its annotated genome sequence, cell extracts were shown to exhibit PPi-dependent phosphofructokinase and pyruvate phosphate dikinase activity. In addition, membrane-bound pyrophosphatase activity wa

A library of donor-acceptor system consisting of cyclopentadithiophene-based polymer photocatalysts have been designed and synthesized. Among all photocatalysts, the active PCPDTBSO achieved hydrogen evolution rates of 24.6 mmol h–1 g–1 with apparent quantum yields of 8.7 % at 500 nm. More importantly, combined the results of photocatalytic efficiency, apparent quantum yield, the time-resolved flu

Attosecond pulses allow the study of electrons on their natural timescale. They are created from the interaction of atoms with ultrashort, intense laser pulses whose electric field approaches the strength of inner-atomic electric fields. This thesis presents experiments around the generation, characterization and application of attosecond pulses. First, we study the influence of the atomic genera

Popular Abstract in English The thesis that you are reading at this moment was printed using climate compensated paper, a sign that consciously or not you are contributing somehow to control the current environmental issues in our planet. It would not be nice if every single article used in your daily life contains information about how environmentally friendly that product is? We have to think “bOxidation reactions are important in organic chemistry as well as in nature. In industry, oxidations are commonly used for the synthesis of chemicals and pharmaceuticals, however such processes have a number of limitations, they use chlorinated solvents, stoichiometric oxidation reagents, and in some cases the reagents that have risks of explosion during transportation and storage. This has called

Electrification of many industries using off-road high power machines presents several problems. In order to analyse the viability of different solutions the logistics, machine operation and power management have to be analysed. In this paper a model is presented that in a novel way combines these problems into a complete system model that can be optimized on several levels. Complex charging schem

Distributed generation, DG, introduces multi-generator grids and new modes of operation. DG will likely introduce power electronic, PE, converters on a large scale at the low- and medium-voltage levels. DC injection into the AC grid is a threat from grid-connected PE converters that are badly structured. Low DC currents in AC current are difficult to measure at those low levels decided in IEEE™ 15

We report on aryl ether-free 2,7-diphenylfluorene-based copolymers tethered with quinuclidinium (Qui) cations via hexyl spacers, prepared through superacid catalyzed Friedel Crafts polycondensation and quaternization reactions. The 2,7-diphenylfluorene monomers were prepared by Suzuki coupling and employed to increase polymer backbone stiffness. Corresponding copolymers and anion-exchange membrane

Driven by the increasing demands on data rate from applications, the wireless communication standard has for decades been evolving approximately at a pace of one generation per ten years. Following this trend, the ambitious plan to replace the current cellular mobile network standard (4G) with the next generation standard (5G) is going through the standardization phase and is getting close to its
