The preparation of oxygen reduction reaction (ORR) and hydrogen evolution reaction (HER) catalysts with high activity, stability and low platinum loading has always been the focus of research. The single-atom platinum supported catalyst greatly improves the utilization of platinum, but the catalytic activity and selectivity are greatly affected by the platinum coordination environment, and the pre

This study comprehensively evaluated the global warming potential of an office building in a newly built Scandinavian neighbourhood seeking to reach sustainability. The primary objective of the research was to support the city authorities of Helsingborg by providing valuable insights into actual carbon emissions at the building level and proposing measures to minimize these emissions to achieve cl

Gated Recurrent Unit (GRU) neural networks have gained popularity for applications such as keyword spotting, speech recognition and other artificial intelligence applications. Typically for most applications training and inference is performed on cloud servers, and the result are transferred to the power constrained device, e.g., an hearing instrument (HI). This approach has disadvantages such as

In Sweden as well as in The Netherlands energy policy is increasingly aiming at extending the use of renewable sources. In accordance with the targets of the European Union, both countries have formulated national targets for the year 2020. For wind energy these targets are 30.0 TWh of electricity in Sweden and a total installed capacity of 10.0 GW in The Netherlands. Wind is an inflexible, variab

The large-scale applications of anion exchange membrane water electrolysis (AEMWEs) and zinc–air batteries (ZABs) are observably limited by the lack of highly active, multifunctional, and industrially applicable electrocatalysts. In this work, we report a solvent-free rapid pyrolysis strategy that successfully prepares a composite material of Pt8V–V2O3 heterostructure supported on nitrogen-doped p

Stochastic reconstruction is widely employed for effective and flexible imitation of Gas Diffusion Layers (GDLs), e.g., to facilitate the study of their properties. However, the reconstruction often overlooks crucial factors such as fiber curvature, fiber stack arrangement, and fiber anisotropy. Consequently, the impact of these structural characteristics remains poorly understood. In this study,

With growing interest in sustainable civil supersonic and hypersonic aviation, there is a need to model the combustion of alternative, sustainable jet fuels. This work presents numerical simulations of several related phenomena, including laminar flames, ignition, and spray flames. Two conventional jet fuels, Jet A and JP-5, and two alternative jet fuels, C1 and C5, are targeted. The laminar burni

Three-dimensional Large Eddy Simulations (LES) are conducted on a non-premixed hydrogen-air annular rotating detonation combustor (RDC). A 22-step finite-rate chemistry reaction mechanism and a flow solver previously developed for high-speed reacting flow are used to perform the LES’. The selected case is an RDC designed by the US Air Force Research Laboratory and has been studied experimentally a

To realize the transition of our society to a low-carbon future with innovative subsurface energy solutions, understanding the dynamic behavior of gas invading multi-fluid systems in underground pore space is critical. In this work, a joint approach of flow imaging and digital image processing is employed to investigate the fingering dynamics of gas invading multi-fluids in porous media. We examin

As the demand for secure software and hardware solutions increase in our modern digitalized society, the importance of reliable and cost-effective product testing is apparent. One such testing technique is fuzzing, which involves generating large amounts of malformed and randomized data to stress test system interfaces. This study aimed to compare traditional fuzzing methods to modern approaches a

Power sector decarbonisation is crucial for meeting global climate targets under the Paris Agreement as well as ensuring sustainable growth. Electricity and heat account for approximately 40% of energy‐related emissions and demand is only expected to increase, facilitating low‐carbon transitions in other sectors, from transport to industry. In response to the limitations of feed-in tariffs and ren

With the urgent demand for ultralow-temperature refrigerators worldwide, the operation reliability and stability of the refrigeration system becomes greatly crucial. In this study, a -80 oC ultralow-temperature cascade refrigeration system (CRS) is developed. From aspects of global warming potential (GWP) and ozone depletion potential (ODP), the environmentally friendly refrigerants R290 and R170
