A Unified Microscopic Picture of Cation and Anion Migration in MAPbI3

Abstract Passivating defects and restricting defect mobilities in halide perovskites to increase device lifetimes has become a main field of research. Modeling structure and mobility of point defects is an essential contribution to this endeavor. We employ molecular dynamics, bas...

Empirical analysis of perceived inaccessibility in the Netherlands

A growing body of research examines how people perceive accessibility, typically drawing from small-scale surveys in either urban or rural areas. The novelty of this study lies in analysing the heterogeneity in the perceived inability to reach different destinations, accounting f...

Hydrodynamic and Magnetostatic Characterization of a Rotating Vortex-Based Nanobubble Generator

This study combines experimental characterization, computational fluid dynamics (CFD) and magnetostatic modelling to investigate a rotating vortex-based nanobubble generator incorporating six permanent magnets. The combined approach distinguishes the hydrodynamic generation pathw...

Identifying Contact Barrier Types in Few-Layer MoS2 Devices Using Correlative IV, LBIC, and Bias-Dependent KPFM

Abstract Electrical contacts between metals and two-dimensional (2D) semiconductors such as molybdenum disulfide (MoS2) critically govern device performance, yet their microscopic and spatially varying contributions are difficult to disentangle with a single technique. Here we pr...

Aerodynamic Promptness of Tilting-Propeller Multirotors

Abstract: This work develops a geometric theory of aerodynamic promptness for multirotor platforms whose propeller directions depend on a smooth orientation-mechanism configuration. The actuator state consists of the actual signed propeller speeds and the mechanism configuration,...

Plasma metabolomics reveals candidate biomarkers associated with individual treatment response in psoriatic arthritis

Psoriatic arthritis (PsA) is a clinically heterogeneous inflammatory disease for which optimal treatment selection remains unclear. Robust biomarkers that predict treatment response and identify patient-specific factors to inform treatment choice could advance precision medicine...

Beliefs undermining protective action against smart speaker privacy risks: perceived benefits, trust in the manufacturer, and nothing to hide beliefs

The uptake of smart speakers in our homes is steadily increasing. While bringing convenience and access to information, they also bring substantial risks to our privacy. In this study, we investigated which factors undermine taking privacy protective action, drawing on people’s b...

Developing a new CT-based bone defect classification in revision knee arthroplasty

Aims To seek consensus on the principles and criteria necessary to develop a CT-based bone defect classification (BDC) for revision knee arthroplasty. Methods A three-round structured Delphi study was conducted. First, five interviews were held with international knee revision ex...

Quantifying local mechanical work at the nanoscale in optically driven piezoelectric membranes

Quantifying mechanical work generation in active micro- and nanoscale systems requires measuring both displacement and force under controlled loading conditions, yet most approaches probe these quantities separately. Here, we present an atomic force microscopy (AFM)-based method...

Cyclic Nanoindentation of Clay Minerals: Micromechanical Insights Into Caprock Integrity for Subsurface Energy Storage

Abstract Clay minerals are key constituents of subsurface caprocks and play a critical role in the long-term containment performance of underground energy storage systems. However, their cyclic mechanical response remains insufficiently understood, despite repeated pressure fluct...

Self-Assembling Nanoparticles to Assess Multivalent Interactions between Influenza A Virus Hemagglutinin and Glycan Surfaces

Abstract The multivalent display of surface glycoprotein hemagglutinin (HA) on Influenza A viruses (IAVs) enhances the overall binding avidity to sialylated glycans on host cell surfaces. While precomplexing HA trimers with antibodies increases multivalency and avidity, this meth...

REScoops acting as intermediaries, influencing the scaling of energy communities; a multi-case analysis of five pilots in Europe

There is increasing scholarly attention to the scaling of energy communities (EC). Intermediaries have an important role here. Energy communities themselves, especially in the form of renewable energy cooperatives (REScoops), can take on this role very well. This paper addresses...

Greening cities to ensure biosphere functional integrity: Insights from Rotterdam and Lagos

The Earth Commission has proposed that 20-25% of every square kilometre of managed lands, including in cities, be reserved for nature to ensure its local functioning and human wellbeing -biosphere functional integrity boundary (BFI). This research adopted a multi-method justice-o...

Interconnected soil properties modulate compound hurricane-dust events that impact the Americas

Abstract In 2024, several Atlantic tropical cyclones encountered trans-Atlantic African dust, altering weather, air quality, and deposition across the Americas. Using state-of-the-art Earth system modeling, this study highlights that interconnected basic (mineralogy, texture) and...

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...

Suppressing agglomeration in salt hydrate reactors via lattice architecture

Salt hydrates are a promising class of thermochemical energy storage materials (TCMs) for heat storage applications. However, their practical deployment is hindered by severe particle agglomeration, especially at large scale, which limits cyclability and leads to performance degr...
