The demand for cost- and time-effective and customizable components for High Vacuum (HV) and Ultra-High Vacuum (UHV) systems has prompted exploration into the application of 3D-printing technology. This study investigates the viability of utilizing 3D-printed plastics in UHV environments by evaluating their outgassing properties. An extensive evaluation of 3D-printing materials was carried out, hi

Toxicity pathways of engineered carbon nanomaterials, which have many and diverse industrial applications, include oxidative stress primarily due to the generation of reactive oxygen species (ROS). This study on 13 carbon black, 6 Graphene nanoplatelets (GNP), and 3 nanodiamond materials identified physicochemical properties driving their ROS production. ROS production was cross-validated using di

This paper examines the influence of artificial intelligence (AI) on recent operatic practice, exploring its potential to affect the development of the genre from the artist’s perspective. While opera has historically evolved in tandem with technological advancements, the integration of AI raises important questions about its function within the operatic toolbox and its relation to the genre’s cor

Let f be a holomorphic self-map of the unit disc. We show that if log(1 − | f (z)|) is integrable on a sub-arc of the unit circle, I , then the set of points where the function f has finite Carathéodory angular derivative on I is a countable union of Beurling–Carleson sets of finite entropy. Conversely, given a countable union of Beurling–Carleson sets, E , we construct a holomorphic self-map of t

It was not a given that petrol-powered cars would come to dominate the world. In fact, back in 1900, just 22% of cars produced in the US were powered by gasoline (also known as petrol, benzine or various other names). The rest split between electric and steam cars.

The use of carbonic anhydrase (CA) as a catalyst for bicarbonate formation in amine solutions has shown the potential to increase the absorption rate of CO2, thus potentially reducing capital cost of a CO2 capture plant, as the size of equipment can be reduced. On another approach, it could replace part of the amine to offer lower environmental impact. In this work, the catalytic effect of CA on t

Background: Interferon-γ release assays (IGRAs) for tuberculosis infection (TBI) cannot distinguish different stages of the TBI spectrum (including spontaneously cleared infection). We investigated patterns of Mtb-specific blood mediators in people with and without TBI during tuberculosis preventive therapy (TPT). Methods: Individuals with likelihood of recent Mtb exposure, aged 15–25 years, with

Biochar has a very wide range of uses in industrial processes, wastewater treatment, agriculture and soil remediation. Scaling up biochar deposits in soils has been proposed for carbon sequestration in the context of climate mitigation strategies. Although certain contaminants in feedstock can be eliminated through pyrolysis, others persist, and the process itself produces additional hazardous sub

Familial Platelet Disorder with associated Myeloid Malignancy (FPDMM, FPD/AML, RUNX1-FPD), caused by monoallelic deleterious germline RUNX1 variants, is characterized by bleeding diathesis and predisposition for hematologic malignancies, particularly myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML). Clinical data on FPDMM-associated AML (FPDMM-AML) are limited, complicating evidence

Food systems have enormous impacts on people and the planet, with agriculture and food research becoming strategic for many countries. However, the way this research is conducted and the rise of new agri-food technologies have ethical and socio-economic implications. To address these, many scholars are gaining interest in participatory methods, such as citizen science, but are unfamiliar with the

High-Arctic environments are facing an elevated pace of warming and increasing human activities, making them more susceptible to the introduction and spread of alien species. We investigated the role of human disturbance in facilitating the spread of a native plant (Papaver dahlianum) in a high-Arctic natural environment close to Isfjord Radio station and along adjacent hiking trails at Kapp Linné

Objective: Meat intake is suggested to affect gut microbiome composition and the risk of chronic diseases. We aimed to identify meat-associated gut microbiome features and their association with host factors. Design: Gut microbiota species were profiled by deep shotgun metagenomics sequencing in 9669 individuals. Intake of white meat, unprocessed red meat, and processed red meat was assessed using

The emergence of a hydrogen economy in Europe and the Nordic region represents one important pathway to decarbonization of critical sectors. This development is and will be shaped by distinctive national strategies that do not fully converge around shared objectives. The landscape reveals a complex interplay of technological innovation, industrial policy, and environmental ambition.Each Nordic cou

Understanding of carbon nanomaterials oxidation is useful in many different applications, e.g., for soot emission abatement, or in defect engineering aiming to improve material properties. In this work, the oxidative behavior of three substantially different qualities of carbon black, multiwall carbon-nanotubes, and few-layer graphene, was studied using a combination of macroscale quantification (

Tomographic surface X-ray diffraction (TSXRD) is an adaptation of classic surface X-ray diffraction to allow for measurements of polycrystalline surfaces. Compared to most other surface-sensitive techniques, surface X-ray diffraction has advantages in operando studies, since it can provide crystallographic information about surface structures in high gas pressures (above atmospheric) as well as th
