A life cycle assessment is presented for a current vehicle’s greenhouse gas impact when using a combination of electrification and renewable fuels. Three degrees of electrification are considered: a hybrid electric vehicle, a plug-in hybrid electric vehicle, and a battery-electric vehicle. These are combined with fuels with various degrees of renewable content, representing a fossil fuel, a first-
A theoretical and experimental study of the gas phase and liquid acetic acid based on resonant inelastic x-ray scattering (RIXS) spectroscopy is presented. We combine and compare different levels of theory for an isolated molecule for a comprehensive analysis, including electronic and vibrational degrees of freedom. The excitation energy scan over the oxygen K-edge absorption reveals nuclear dynam
Two concurrent trends may fundamentally change how we understand the role of solar PV at high latitudes. Until now, relatively low annual insolation in combination with low electricity demand during the summer months has not favoured PV in the Arctic. However, continued decreases in costs for PVs in combination with increasing electricity demand from industrial electrification is quickly changing
Decoupling key intermediates’ adsorption via asymmetric 3d-5d-orbital hybridization overcomes the intrinsic scaling relation bottleneck, enabling rational design of high-performance, durable multifunctional electrocatalysts for anion exchange membrane water electrolyzers (AEMWEs) and Zn–air batteries (ZABs). Here, we reveal that asymmetric 3d-5d-orbital hybridization, engineered through the synerg
Few-cycle laser pulses are fundamental for tracking ultrashort motions such as electron dynamics and achieving stronger fields. They are also extensively used to perform high-harmonic generation and in attosecond science. However, generating stable and high quality few-cycle pulses requires a simultaneous control of bandwidth and dispersion. The generation of few-cycle pulses in an efficient manne
Dokument3 The generational goal – changes of consumption patterns and their environmental impacts Purpose and perspectives The purpose of this research programme is to study the generational goal, which is a political goal, adopted by the Swedish parliament in June 2010 and supported by several parliamentary parties. According to the generational goal, “the overall goal of Swedish environmental po

Power production represents one fourth to one third of all CO2 emissions. Carbon Capture and Storage (CCS) in one way to approach the increasing problem with CO2 emissions from fossil fuelled power plants. The CO2 is separated, compressed and transported to a final storing site. To allow more efficient transport and to match the pressure of the final storing site, the CO2 is compressed to a superc
Humanity’s ever-growing energy demands require the implementation of more sustainable ways to harvest and store energy. At the same time, the reduction of greenhouse gas emission and thus global warming remains of paramount importance. To this end, solar energy harvesting presents an attractive route towards satisfying these requirements—be that by conversion to thermal energy, electricity or to c
The use of energy gases with renewable origins will become important with diminishing fossil resources. This as the infrastructure of the gaseous fuels is well built out and the distribution networks already exist. LPG is one of the most versatile fuels around, perfect for rural areas and in many other applications. The fossil origin of the fuel will, in today’s climate and environmental debate, h
Byggproduktion idag, innebär bland annat en hög energianvändning, utsläpp av växthusgaser, användning av miljöfarliga ämnen samt stora mängder avfall som måste hanteras. Detta är aspekter som samtliga behöver minskas för att reducera branschens stora miljöpåverkan. Inom byggsektorn har klimatarbetet fått en alltmer ökad uppmärksamhet med införandet av olika klimatkrav på nationell och EU-nivå. I oCarbon offsets, essential in climate-related aspirations for governments and businesses, entail reducing, avoiding, or extracting greenhouse gases from the atmosphere, even if not contemporaneous with emissions. They include, among others, energy-efficient solutions and renewable energy investments. These compensations, voluntary or regulated, must meet reliability criteria. Actions, such as Carbo

This master thesis was done in cooperation with the Danish district heating company, Vestegnens Kraftvarmeselskab I/S. VEKS is a transmission company supplying heat in western Copenhagen, Denmark. VEKS wanted a global analysis over the possibilities to decrease the cost and carbon dioxide emissions from purchased heat through decentralized accumulation. To cover all economical and environmental re
Ultra-low power (ULP) biomedical implants and sensor nodes typically require small memories of a few kb, while previous work on reliable subthreshold (sub-VT) memories targets several hundreds of kb. Standard-cell based memories (SCMs) are a straightforward approach to realize robust sub- VT storage arrays and fill the gap of missing sub-VT memory compilers. This paper presents an ultra-low-leakag
The challenge of multi-use forestry is to fulfil a range of economic, ecologic and social goals in a sustainable way, accounting for synergies and trade-offs among the ecosystem services provided. Climate changes add to the complexity via effects on forest ecosystem processes, such as primary production and respiration, and also by adding a new goal on the agenda: the role of forests in climate mi
Fuel cells produce low quantities of local emissions, if any, and are therefore one of the most promising alternatives to internal combustion engines as the main power source in future vehicles. It is likely that urban buses will be among the first commercial applications for fuel cells in vehicles. This is due to the fact that urban buses are highly visible for the public, they contribute signifi
Adipocytes play a central role in energy balance, and dysfunctional adipose tissue severely affects systemic energy homeostasis. The ATPase EH domain-containing 2 (EHD2) has previously been shown to regulate caveolae, plasma membrane-specific domains that are involved in lipid uptake and signal transduction. Here, we investigated the role of EHD2 in adipocyte function. We demonstrate that EHD2 pro
Coherent X-ray imaging techniques, such as in-line holography, exploit the high brilliance provided by diffraction-limited storage rings to perform imaging sensitive to the electron density through contrast due to the phase shift, rather than conventional attenuation contrast. Thus, coherent X-ray imaging techniques enable high-sensitivity and low-dose imaging, especially for low-atomic-number (Z)
