Yttria-stabilized zirconia (YSZ) is the benchmark oxygen-ion conductor and is widely regarded as electronically inert under oxidizing conditions. Yet its electrical behavior at the nanoscale remains unsettled. While bulk YSZ exhibits predominantly ionic transport, electronic contributions have only been reported under highly defective, porous, or strong-field conditions. Here, we demonstrate that

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.

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

Background: Central venous catheters (CVCs) are commonly used in patients with haematological diseases but are associated with infectious complications. The CVC Anti-infection Double Lumen Bundle was introduced in December 2020 to reduce this risk. The bundle included a double-lumen noble metal alloy–coated CVC and chlorhexidine-impregnated dressings. This study evaluated whether the bundle was as

This thesis consists of four self-contained papers in the economics of education and labor economics.In the first chapter, we study whether differences in teacher quality across countries are a contributor of international learning gaps. In particular, we study the effects of two dimensions of teacher quality, subject knowledge and didactic skills, on student learning in francophone Sub-Saharan Af

The accelerating global energy transition has intensified demand for energy transition minerals (ETMs), many of which are located on or near Indigenous lands. While ETMs are essential for decarbonisation, their extraction often reproduces entrenched patterns of socio-ecological injustice and generates new pressures on Indigenous Peoples, territories, and ways of life. Free, Prior and Informed Cons

Fragility fractures are a major health concern and accurate estimation of bone strength is important for fracture risk assessment. Finite element (FE) models can provide reliable estimates of femoral bone strength, but traditional approaches typically require three-dimensional imaging and computationally intensive model generation. Previous research has enabled reconstruction of subject-specific F

Förvaltningsmyndigheter fyller en uppsjö av funktioner i det svenska sam hället och offentligt anställda fäller i utövandet av yrkesroll en stor mängd brett varierade beslut och uttalanden. Med tanke på vilken effekt dessa utta landen kan få för allmänheten kan man fråga sig vilka av en myndighets ställningstaganden som utgör ett överklagbart beslut. Frågan om förvalt ningsbesluts överklagbarhetAdministrative authorities fulfill a plethora of functions in Swedish society and public employees make a large number of widely varying decisions and statements when exercising their professional role. Considering the effect these statements can have on the public, one can ask which of an authority's positions constitute an appealable decision. The question of the appealabil ity of admini

The introduction of a semiconductor–semiconductor junction is an effective strategy to enhance the photocatalytic performance of perovskite nanocrystal-based systems. Herein, we optimized the synthesis of CsPbX3/Pb4S3Y2 (X, Y = Cl, Br, I) perovskite/chalcohalide heterostructures, whose band alignment can be tuned by the halide composition. As a proof-of-concept, we evaluated the photooxidative cou

Coffee is the most common drink in the world, second only to water. This makes caffeine, the ingredient of coffee known for its wakefulness-promoting effects, one of the most used psychoactive substances. The psychoactive property of caffeine is well-characterized, and entails its interaction with the adenosine receptors, involved in sleep regulation. While studies have shown a deleterious immedia

The focus of this study was to evaluate the feasibility of incorporating Perlin noise, a method that has previously been used to model the tissue distribution of software breast phantoms, when creating a ‘compressible’ software breast phantom used in finite element analysis. Several compressible phantoms were created to represent different stages of aging in a virtual patient when younger, fibrogl

Aluminum (Al), as a carbon-free energy source and energy carrier, features favorable characteristics regarding its production, transportation, utilization, and recyclability. However, the understanding of Al gas-phase combustion kinetics is still limited. The novelty of this work lies in presenting the first detailed and comprehensive analysis of the Al gas-phase mechanism in the air and steam env
