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
Background Today many large corporations worldwide are facing new competitors that develop good enough products to a low price. This is a well-known problem for large companies and is not an industry specific problem. We have seen new entrants especially from Asia entering, ranging from the airline industry, grocery, retailing, wind energy market, banking to IT services. These are just examples an
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

Laser-induced fluorescence has been a staple technique for in-situ probing of radicals and atomic species for decades. The multi-photon equivalent is prevalent in a large variety of applications, where such excitation schemes enable the study of otherwise elusive species and systems. However, these variants inherently suffer from low signal intensities, impeding the broader use of multi-photon ima
We predict an unexplored type of ultrastrong coupling between atoms and intense ultraviolet light that leads to giant population oscillations on the attosecond timescale. These counter-rotating oscillations stem from the interference of energy-conserving and nonconserving photon absorption and emission processes via Rydberg states. They can be of similar amplitude as the elementary femtosecond Rab
Today, wearable systems are facing fundamental barriers in terms of battery lifetime and quality of their results. The main challenge in wearable systems is to increase the battery lifetime, while maintaining the machine-learning performance of the system. A recently proposed concept for overcoming this challenge is self-awareness, which increases system's knowledge of itself and the surrounding e
We experimentally observe longer than long trajectory influence in high-order harmonic generation (HHG) by varying the peak intensity of the driving laser field either through direct attenuation or by chirping the laser pulse. Using a theoretical Gaussian beam model to simulate spatial interference resulting from quantum path interference, we show that the measured interference patterns cannot be
Induction heating of CFRP is an energy-efficient and fast method that may be used for example during consolidation of thermoset-based CFRP or welding of thermoplastic-based CFRP. This study investigates how induction heating of CFRP is affected by the temperature dependence of the thermal and electrical properties and presents a simple numerical model for computation of the temperature distributio
Global climate change stands out from most environmental problems because it will span generations and force us to think in new ways about intergenerational fairness. It involves the delicate problem of complex coordination between countries on a truly global scale. As long as fossil fuels are too cheap, climate change policy will engage all major economies. The costs are high enough to make effic
We have temporally characterized, dispersion compensated and carrier-envelope phase stabilized 1.4-cycle pulses (3.2 fs) with 160 mu J of energy at 722 nm using a minimal and convenient dispersion-scan setup. The setup is all inline, does not require interferometric beamsplitting, and uses components available in most laser laboratories. Broadband minimization of third-order dispersion using propa
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
We use a strong two-colour laser field composed of the fundamental (800 nm) and the second harmonic (400 nm) of an infrared (IR) laser field to generate attosecond pulses with controlled spectral and temporal properties. With a second-harmonic intensity equal to 15% of the IR intensity the second-harmonic field is strong enough to significantly alter and control the electron trajectories in the ge
This paper reviews and extends searches for the direct pair production of the scalar supersymmetric partners of the top and bottom quarks in proton-proton collisions collected by the ATLAS collaboration during the LHC Run 1. Most of the analyses use 20 [Formula: see text] of collisions at a centre-of-mass energy of [Formula: see text] TeV, although in some case an additional [Formula: see text] of
The aim of this thesis is to set up a high-fidelity fluid structure interaction (FSI) simulation environment to study the gust load alleviation capability of camber-morphing airborne wind energy (AWE) wings. The simulation environment will enable studying the transient flow phenomena around the wing when encountering wind gusts and gives the possibility of investigating dynamic instabilities. To m
