Idag transporteras stora mängder gods runt om i världen med lastbilar och fartyg, vilket förväntas fortsätta även i framtiden då det är avgörande för samhällets funktion. Det vanligaste framdrivningssystemet för dessa fordon är kompressionständningsmotorn, även känd som dieselmotorn, som då vanligtvis drivs av fossilt dieselbränsle. Detta resulterar i betydande utsläpp som måste minskas, för att uIn today's world, the transportation of goods via trucks and ships plays a pivotal role, and this trend is expected to persist in the foreseeable future, owing to its critical importance to society. However, the most common propulsion system for these vehicles, the compression ignition (CI) engine, commonly known as the diesel engine, relies heavily on fossil diesel fuel, resulting in significant

The adsorption of water and coadsorption with oxygen on Rh{111} under ultrahigh vacuum conditions was studied using synchrotron-based photoemission and photoabsorption spectroscopy. Water adsorbs intact on the clean surface at temperatures below 154 K. Irradiation with x-rays, however, induces fast dissociation and the formation of a mixed OH+H2O layer indicating that the partially dissociated lay

This paper discusses the compression ratio influence on maximum load of a Natural Gas HCCI engine. A modified Volvo TD100 truck engine is controlled in a closed-loop fashion by enriching the Natural Gas mixture with Hydrogen. The first section of the paper illustrates and discusses the potential of using hydrogen enrichment of natural gas to control combustion timing. Cylinder pressure is used as

In2O3-based catalysts have shown high activity and selectivity for CO2 hydrogenation to methanol; however, the origin of the high performance of In2O3 is still unclear. To elucidate the initial steps of CO2 hydrogenation over In2O3, we have combined X-ray photoelectron spectroscopy and density functional theory calculations to study the adsorption of CO2 on the In2O3(111) crystalline surface with

Cu2O has emerged as a promising material for sustainable hydrogen production through photoelectrochemical (PEC) water splitting, while inefficient charge separation remains one of the main challenges hindering its development. In this work, a new architecture of InAlN/Cu2O heterojunction photocathode is demonstrated by combining n-type InAlN and p-type Cu2O to improve the charge separation efficie

IT ses ofta som en del av lösningen för att uppnå ett hållbart samhälle genom till exempel minskat resande, optimering av industri- och jordbruksprocesser, intelligenta elmätare och smarta hem. Något man sällan reflekterar över är att ITbranschen själv också bidrar till elanvändningen. Ett nytt fenomen inom IT-världen är molnet som ger möjlighet till som det verkar outtömliga resurser i form av laInformation and communication technology (ICT) is often seen as part of the solution for a sustainable society, for example through reduced travel, optimization of industrial and agricultural processes, smart meters and smart homes. However, something usually left unconsidered is the electricity consumption of ICT itself. A new phenomenon of the ICT industry is the Cloud that enables seemingly ine

Ocean evaporation, represented by latent heat flux (LE), plays a crucial role in global precipitation patterns, water cycle dynamics, and energy exchange processes. However, existing bulk methods for quantifying ocean evaporation are associated with considerable uncertainties. The maximum entropy production (MEP) theory provides a novel framework for estimating surface heat fluxes, but its applica

The relative energies of different coordination modes (bidentate, monodentate, syn, and anti) of a carboxylate group bound to a zinc ion have been studied by the density functional method B3LYP with large basis sets on realistic models of the active site of several zinc proteins. In positively charged four-coordinate complexes, the mono- and bidentate coordination modes have almost the same energy

We investigate the possibility of using transient absorption of a coherent bound electron wave packet in hydrogen as an attosecond pulse characterization technique. In a recent work, we have shown that photoionization of such a coherent bound electron wave packet opens up for pulse characterization with unprecedented temporal accuracy - independent of the atomic structure - with maximal photoemiss

In synchrotrons, nonuniform fill patterns, which give rise to beam phase transients and a spread in synchrotron tune between bunches, have been observed to damp longitudinal coupled-bunch instabilities driven by higher-order modes in rf cavities. The transients are especially large in the presence of Landau cavities, which are used commonly in storage-ring light sources and particularly in the new

Landau cavities used to lengthen the bunches in storage rings necessarily constitute a significant impedance. Because of the particular phase of the field required for bunch lengthening, they are often detuned quite considerably from resonance, more so than the main cavities. As a result, their impedance can excite the first coupled-bunch mode such that it becomes unstable. This phenomenon has pre

The discipline of Artistic Research in Music attempts to study the complexity of real-world artistic production and practice. The strength of this programme resides in the experimental attitude towards how art creation and research impact one another. Further, we study how technical tools can acquire epistemic status and impact the semantic underlay of the creative output. Such dialectics between

The role of sulphur in the production of hydrogen in the small-scale for fuel cell applications is an important topic in the design of such systems and this review of the literature state-of-the-art has been performed to shed light on some of the possible trade-offs that will have to be done in designing these systems. The review-paper summarises the literature with respect to sulphur-laden cataly
