Durable and high-performing anion-exchange membranes (AEMs) are key components in alkaline water electrolyzers and fuel cells. As potentially more sustainable and cost-effective alternatives to proton exchange membrane (PEM)-based systems, AEM-based devices can operate without platinum-group metal catalysts or perfluorinated polymers. However, their broader practical implementation remains limited
The study of fluid transport in porous media is crucial for many applications in science and engineering. From a modeling perspective, understanding how diffusion parameters behave when microstructural variations are taken into account is a significant step toward achieving more detailed and accurate model predictions. It is widely recognized that hydraulic tortuosity is typically approximated as
Optimization and electrical control of photovoltaic (PV) and proton exchange membrane (PEM) electrolyzer systems are critical for efficient, scalable hydrogen production. Static coupling methods employ fixed electrical interconnections between PV arrays and the PEM stack, which cannot adapt to fluctuating irradiance or temperature. To overcome this, we propose an adaptive reconfiguration optimizat
A fundamental aspect of describing vocal activity is to quantify its overall level. For instance, everyone agrees that animals become more vocal when they are excited or stressed, but what does it mean to be ‘more vocal’? Increased duration of individual calls and their repetition rate are the most commonly reported temporal markers of arousal, but proportion of time [spent] vocalising (PTV) appea
Corrosion of prestressing steel in post-tensioned (PT) cables is a critical issue in prestressed concrete bridges, often leading to brittle and unexpected failures. This deterioration is primarily attributed to construction flaws such as inadequate grout injection and the use of poor-quality mortar. This paper presents a probabilistic model for estimating the number and spatial distribution of gro
Inhibition of several of the 10 hallmarks of cancer (Hanahan and Weinberg) would result in a broader and more durable treatment compared to current single or combination drug treatments. Galectin-1 and galectin-3 have been proposed to together be involved in all 10 hallmarks, suggesting that development of a combined galectin-1/3 inhibitor would be beneficial. Specificity toward galectin-1 or -3 c
Att skapa fasta förbindelser mellan länder genom att bygga broar eller tunnlar är mycket kostsamt, men politiska beslutsfattare hoppas i allmänhet att dessa gigantiska infrastrukturprojekt ska öka internationella handelsflöden. Vi utnyttjar öppnandet av Öresundsbron för att testa om det stämmer. Vårt forskningsprojekt visar att Sverige och Danmark handlar ca 25 procent mer med varandra än man sku
Sustainability standards and ratings do not generate enough information for businesses to understand their environmental impacts across scales and create mitigation plans to avoid further transgression of planetary boundaries.
Among historians and archaeologists, the medieval towns of Roskilde and Lund have been perceived as almost twin towns. Both were founded in the late 10th century, with bishop’s seats established in the 11th century. Both quickly rose to become the most politically, economically, and culturally important ecclesiastical centres in southern Scandinavia, with similar urban landscapes dominated by nume
Objectives: To evaluate the impact of the 2018 switch from PCV13 to PCV10 in Sweden’s childhood immunisation programme on the serotype distribution of Streptococcus pneumoniae.MethodsRespiratory tract (RT) S. pneumoniae isolates (n=1615; 2020–2023) were serotyped, tested for antimicrobial susceptibility and compared with invasive pneumococcal disease (IPD) isolates (n=397) and PCV13-era data (2016
Electrostatic energy plays a pivotal role in the minimization of the free energy of self-assembling oppositely charged ions. This is a fundamental principle that guides the formation of aggregates and the separation of phases characterized by a stoichiometric balance between the opposite charges. However, this study unveils the self-assembly of catanionic nanotubes from a mixture of oppositely cha
This paper explores guldgubbar, small gold foil figures from Vendel Period Scandinavia (c. 550–800 CE), through a new materialist lens, moving beyond representational interpretations rooted in Cartesian thought, that usually frames images to be in stasis. Instead of seeking a singular meaning, the study focuses on the figures’ materiality, affective qualities, and ontological openness. Drawing on
