Photocatalytic nitrogen reduction requires the concerted transfer of six electrons and six protons, where inefficient electron utilization and proton supply represent the critical limiting factors for proton-coupled electron transfer in this process. A key challenge lies in hole accumulation within photocatalysts, as hole transfer typically proceeds 2 to 3 orders of magnitude more slowly than elec

Previous studies revealed that grammatical gender may shape perception and categorisation, yet the extent of this influence remains unclear, specifically in simultaneous bilinguals with two gendered languages. This pre-registered ERP study investigates how two partially contrasting grammatical gender systems modulate perception in Ukrainian-Russian bilinguals. Twenty-six participants completed a n

Foraminiferal shells are abundant in marine sediments, well preserved, and morphologically sensitive to environmental conditions, making them widely used archives of past marine environments and oceanographic changes. In particular, foraminiferal pore traits are promising proxies for past ocean oxygenation. However, conventional 2D measurements from limited shell regions may obscure chamber-wise a

Objective: To examine the extent to which epididymo-orchitis or urinary tract infections (UTI) may precede testicular cancer (TC) in Sweden. Methods and analysis: We conducted a nationwide, open-cohort study including 8 382 433 men between 1964 and 2018. Standardised incidence ratios (SIR) with 95% CIs were calculated to compare TC incidence rates in men diagnosed with epididymo-orchitis or UTI—ei

In order to fully utilize the technological potential of unconventional superconductors, an enhanced understanding of the superconducting mechanism is necessary. In the best performing superconductors, the cuprates, superconductivity is intimately linked with magnetism, although the details of this coupling remain elusive. Here, we address this gap by studying the electron-doped cuprate Nd1.85Ce0.

Increased soil organic carbon (SOC) sequestration reduces atmospheric CO2 and builds soil health. A conversion from annual crops to perennial crops may decrease negative environmental impacts and promote desired ecosystem services. Soil carbon credit systems and environmental monitoring require reliable verification of SOC change. Here we report a baseline survey of SOC for an agricultural study s

The sensitivity of Ramsey interferometry experiments is governed by the interplay between the beam phase-space distribution and the magnetic field environment through which the spins propagate. Quantitative optimisation thus requires a consistent treatment of optics, magnetics and spin dynamics. We present a simulation framework that enables such an analysis by combining neutron optics simulations

In Sweden, peak-hour travel demand is ranked as the most important operational cost driver for public transport, linked to school and work hours. Achieving a more balanced demand throughout the day is therefore crucial for resource efficiency and promoting environmentally friendly transport. This study aims to gain a deeper understanding of the process of implementing staggered school start times

Ovarian malignancy is the most lethal gynecologic tumor, with an 80% relapse rate and 47% five-year survival. Epithelial ovarian cancer (EOC), the most common form, comprises five major histotypes with distinct clinicopathological characteristics, yet treatment still relies largely on cytoreductive surgery and platinum-based chemotherapy. Phosphoproteomics enables the mapping of protein phosphoryl

Corrosion of embedded steel liners in nuclear containments threatens structural integrity and is challenging to detect. Acoustic emission (AE) and nonlinear ultrasonic cross-modulation were applied to monitor cracking in a concrete cube with an embedded steel plate under galvanostatic corrosion. AE showed intense early activity from rapid crack initiation. The modulation index (MI) dropped during

Sammanfattning Titel Att operationalisera DPP: tolkningar, utmaningar och kollektiv samordning i den ultimata försörjningskedjan Författare Adam Rukundo Bakgrund Digitala produktpass (DPP) införs genom EU-lagstiftning och kommer att kräva att strukturerad produktdata görs tillgänglig digitalt tvärs över olika industrier. Kraven fastställs i ekodesignförordningen, batteriförordningen och byggprodukAbstract Title Operationalising the Digital Product Passport: Interpretation, Challenges and Collective Coordination across the Ultimate Supply Chain Author Adam Rukundo Background The Digital Product Passport (DPP) is introduced through European Union legislation and will require structured product data to be made available across the supply chain. Requirements are established through the Ecode

The increasing penetration of renewable energy and the growth of digital electricity demand expose high-renewable Nordic microgrids to coupled uncertainty in renewable output, electricity prices, carbon intensity, and load demand. This coupling intensifies the operational trilemma among low-carbon supply, economic efficiency, and system reliability. Conventional microgrid scheduling methods usuall

In light of the ongoing energy transition, solar photovoltaic (PV) systems are becoming increasingly widespread. The intermittent nature of solar power introduces challenges to grid operation, which is why PV power forecasting has emerged as an important research topic. While existing research mostly focuses on single-site forecasting, this thesis compares sites from four different Köppen-Geiger c

This thesis examines whether aerial bombing during the Spanish Civil War shaped the long-run demographic trajectories of Catalan municipalities. Using municipal-level bombing data and population records from 1900 to 2000, the analysis combines OLS regressions, difference-in- differences, an event study, and heterogeneity by settlement type. The results show that bombed municipalities were already

During the last few years, we have seen an increase of extreme weather events because of climate change in many municipalities in Sweden. These weather events have had a destructive effect on both municipal and private properties. According to past research the climate adaptation has mainly come from the public sector, but to increase society’s resilience to the effects of climate change we need a

Biologisk mångfald har idag en betydande roll inom byggnation av hållbar infrastruktur. Samtidigt har utbyggnaden av elnätet och elektrifieringen ökat för att bidra till ett fossilfritt samhälle. Utbyggnaden av elnätet sker i form av fördelningsstation och ledningsgator. Denna studie undersöker vilka begränsningar det finns för att använda fördelningsstationer som en yta för att bidra till den bioBiodiversity has become an increasingly important aspect of sustainable development in infrastructure. At the same time electrification plays an important role for a fossil-free society and the increasing need for electrical infrastructure such as substations. This study examines the limitations and opportunities for implementing biodiversity enhancing measures at two substations in southern Swede
