Stable and efficient n-type scaffolded semiconductor for photocatalytic hydrogen production under tungsten light irradiation

Abstract The production of green hydrogen (H 2 ) is a sustainable strategy to address the current energy crisis without contributing to long-term greenhouse gas emissions. Many powder-based photocatalysts have shown great promise for light-driven H 2 generation; however, in eithe...

Beyond Scalar Objectives: Expert-Feedback-Driven Autonomous Experimentation for Scientific Discovery at the Nanoscale

Abstract Self-driving laboratories or autonomous experimentation are emerging as transformative platforms for accelerating scientific discovery. Bayesian optimization (BO) is among the most widely used machine learning frameworks in self-driving laboratories, but these BO-based f...

Visual cue properties determine innate orientation strategy in Monarch butterflies

Animals use a wide range of environmental signals, including celestial and terrestrial cues for navigation. While celestial cues, such as the sun, play a major role in maintaining a constant heading during long-distance migration and dispersal, terrestrial cues provide an animal...

Revisiting air stability effects on whitecap coverage

The article addresses air stability effects on whitecap coverage at sea. This is achieved by using the logarithmic mean wind speed profile including a stability function as well as adopting two sea surface roughness formulas. The results are valid for wind waves in local equilibr...

Assessment of perceived competence in aquatic education: Aspects of reliability and validity of the Perceived Swimming Competence Assessment Scale

The objective of this study was to examine the psychometric properties of a new scale, Perceived Swimming Competence Assessment Scale (PSCAS), designed to assess perceived swimming competence in children. The scale is aligned with skills assessed in the Swimming Competence Assess...

Learning from cyberattacks: how problem-focused coping enables individual and organisational learning in a cybersecurity context

Purpose During a cyberattack, employees who resort to problem-focused coping are more likely to respond effectively and learn from that experience. However, little attention has been given to how organisations can promote problem coping and how organisations can learn from a real...

When simulator experiences shape later choices: Measuring behavioural spillover on travel preferences

Behavioural spillover, where one behaviour affects others, non-targeted behaviours, is widely studied in psychology but underexamined in transport, despite its potential to improve sustainability. We offer a novel contribution by combining an immersive and feedback-supported driv...

Insect outbreak progression over three years shapes biogenic volatile emissions in a mountain birch forest

Abstract Geometrid moth outbreaks are important natural disturbances in mountain birch ( Betula pubescens ssp. czerepanovii ) forests of northern Fennoscandia and are expected to intensify with climate change. Impacts of these outbreaks and moth herbivory on biogenic volatile org...

Enabling climate action: A nexus approach for delivering co-benefits across biodiversity, water, food, and health

Climate response options rarely affect biodiversity, water, food, and health in uniform ways. This comparative analysis examines why technically viable response options generate uneven cross-nexus outcomes, and how governance and justice conditions shape whether these outcomes be...

Molecular dynamics reveals functional group control of Rhodamine B hydrochar adsorption

Abstract This study elucidates the molecular mechanisms of Rhodamine B (RHB) dye removal from aqueous solution using hydrochar adsorbents through comprehensive molecular dynamics simulations. Three model hydrochars were evaluated across a wide range of concentrations: mixed oxyge...

MEE-Net: a lightweight CNN with interpretability assessment for cardiomegaly detection from chest X-rays on edge devices

Abstract Cardiomegaly is a clinically important indicator of cardiovascular risk, yet its detection from chest radiographs remains challenging due to inter-observer variability and the limited deployability of current deep learning models in resource-constrained settings. To addr...

Exogenous melatonin and photoperiodic regulation of melatonin membrane receptors, steroidogenesis and testicular histomorphology in sexually mature guinea fowl (Numida meleagris)

Seasonal reproduction in birds is regulated by photoperiod and melatonin through receptor-mediated signaling. However, their combined effects on testicular steroidogenic pathways, melatonin receptor expression and antioxidant defence-related gene expression remain poorly understo...

Cyber-Physical Testing of Wind-Assisted Ships: Recent Developments and Open Data Set for the SOBC-1 Bulk Carrier

Abstract This paper presents recent improvements in the cyber-physical test method for wind-assisted ships at SINTEF Ocean. In particular, a dynamic lifting line method, that interacts in real-time with the physical ship model, enables now modelling transient aerodynamic effects,...

Space-Time Waveform Relaxation Multigrid for Navier–Stokes

Abstract. Space-time finite-element discretizations are well-developed in many areas of science and engineering, but much work remains within the development of specialized solvers for the resulting linear and nonlinear systems. In this work, we consider the all-at-once solution...

Sea Level Rise Damages on Ecosystem Quality─A Life Cycle Impact Pathway

Abstract Climate change causes species extinction not only by the direct increase in surface temperatures but also by indirect mechanisms, like sea level rise (SLR). These indirect mechanisms are rarely integrated into environmental impact assessment methods, such as life cycle a...

Anisotropic Defect Diffusion in Layered CsPbBr x I3– x Perovskites

Abstract Mixed-halide perovskites offer a route to enhance phase stability and modify optoelectronic properties. Here, we use large-scale molecular dynamics simulations with a reactive force field to investigate defects in CsPbBrxI3–x perovskites, focusing on how defect mobility...

Systemic usability failures in ECDIS: a Swiss cheese analysis of the Kaami accident

Abstract This paper presents several considerations based on the grounding accident of the small Norwegian bulk carrier Kaami in Scotland 2020, a case which shows surprising deviations in the set-up, pre-voyage use, and the way the Electronic Chart Display and Information System...

UAV icing: system identification of leading-edge rime-ice effects on a small fixed-wing drone

Abstract As small fixed-wing unmanned (or uncrewed) aerial vehicles (UAVs) are increasingly deployed for long-endurance, beyond visual line-of-sight (BVLOS) missions, atmospheric icing has emerged as a critical operational hazard. One of the barriers to safe flight in these condi...

Strain-Mediated PVA-MIP–NiO Coupling for Molecularly Selective Magnetic Response

Molecularly imprinted polymers (MIPs) provide exceptional chemical selectivity; however, existing MIP-based sensors primarily rely on electrical, optical, or electrochemical transduction mechanisms. Here, we introduce a hybrid materials concept based on the integration of a poly(...
