Using paleomagnetic observations and geodynamo simulations to assess Earth's magnetic field morphology and variability

Multiple strategies have been suggested for quantitatively comparing numerical dynamo simulations to geomagnetic field models and paleomagnetic observations. Observationally-constrained metrics are designed to infer properties of simulations that are required to produce Earth-like behaviour and enable inferences on otherwise inaccessible properties of the geomagnetic field, such as its long-term spatio-temporal behaviour at the core-mantle boundary. However, these criteria are derived from data spanning differing timescales with fundamentally different spatio-temporal resolution, are often applied in isolation, and may not be independent assessments, so that holistic syntheses of simulated and observed field variations are currently lacking. In this work, we apply 14 existing criteria measuring field morphological and variability properties on centennial to million-year timescales to a database of 207 dynamos. Individual metrics are matched over various ranges of core-mantle boundary dipolarity (𝑓𝑑 ) and its temporal variability (𝛿 𝑓𝑑 ), though no single range conforms with all proposed metrics. The greatest overlap between simulations matching disparate criteria occurs for 𝑓𝑑 = 0.50−0.64, which is lower than the modern field value of 0.65−0.71 (1900-2025). Earth-like dynamos tend to have magnetic/kinetic energy ratio >1, consistent with a MAC force balance, and require a magnetic Reynolds number 𝑅𝑚 = 750−1200 to match the secular variation timescale. Simulations in our dataset exhibit reduced temporal variability at moderate dipolarity (𝑓𝑑 ∼ 0.5) compared to inferences from global field models, which hinders their capacity to produce Earth-like polarity reversals. This is a correction of the original manuscript where the 𝑓𝑑 value in 2025.0 was incorrectly stated. We thank Julien Aubert for his careful reading and suggestion which is now incorporated.

Planetary Dynamo Simulation Explorer: a filterable and visualisable web-based, community-driven catalogue

We present a new web tool, Planetary Dynamo Simulation Explorer, to survey available published simulations of rapidly rotating spherical dynamos.With numerical codes and computers being increasingly efficient, recent years have seen a surge in the number of publications presenting such computations.Our tool comes as an interactive catalogue that allows exploring existing dynamos with respect to input and output dimensionless parameters, choosing from various dynamo setups (e.g. choice of boundary conditions, couplings at play, etc.), with the possibility to test scaling laws on a filtered set of simulations.It also links each dynamo to its associated publication and possibly to online datasets. Alongside the cataloguing work, and to enhance comparability across various setups, conversion rules are explicitly derived and aggregated from previous studies and applied on a broad scale for the first time.Thought of as a collaborative and scalable initiative, the web interface allows uploading new simulation metadata.The whole interface, displayed as a website, is designed for the community to have a better overview while driving transparency, open-source initiatives, and FAIR principles (Findable, Accessible, Interoperable, Reusable).We encourage the community to explore and contribute to it at https://geodyn.univ-grenoble-alpes.fr/explorer/

Negative Ion Surface Production: a comparison between the C12A7 electride and gadolinium

In the context of ion sources for Neutral Beam Injection (NBI) in magnetically confined nuclear fusion plasmas, negative ion production on two different surface materials exposed to low-temperature, low-pressure deuterium plasma is investigated. A novel electride material, promising for its potential to enable highly efficient negative ion production, is compared to gadolinium, a low work function metal, with the aim of highlighting both similarities and differences in surface-driven negative ion formation. For both materials, negative ion yields and surface work functions are measured. The lowest work function obtained for the electride material is 2.7 eV, higher than the previously reported value of 2.4 eV. No clear correlation is observed between the negative ion yield and the work function for the electride highlighting a behavior with respect to negative-ion production which is not the one of a metal . In contrast, gadolinium exhibits the expected behavior with a clear correlation between yield and work function. The lowest work function measured for gadolinium is 2.2 eV, a value comparable to that of caesium, the material currently used in NBI sources, and significantly lower than the tabulated value for pure gadolinium (2.9 eV), likely reflecting the influence of surface impurities.

Characterization of a Plasma Source for Water Treatment Using Electrical, Optical, and Chemical Diagnostics

Hospital and urban wastewaters constitute major reservoirs of multidrug-resistant bacteria (MRB), antibiotic resistance genes (ARGs), and persistent pharmaceutical contaminants, which are only partially removed by conventional treatment plants. As a result, these pollutants are frequently detected in treated effluents destined for environmental discharge or reuse, raising serious public health concerns-especially for agricultural irrigation. This study explores a novel immersed dielectric barrier discharge (DBD) plasma source engineered for point-of-use decontamination of wastewater at emission sites. The plasma device was thoroughly characterized by electrical, optical, and chemical diagnostics to elucidate its operating regimes and capacity to generate reactive oxygen and nitrogen species (RONS) at the plasma-liquid interface. Findings demonstrate that the composition of the carrier gas critically shapes the production and transfer of short-and long-lived oxidants into the liquid phase. These results provide quantitative insights that support the ongoing optimization of plasma-based advanced oxidation systems for decentralized water treatment. They further illustrate how the careful control of plasma and gas composition can enhance the formation and transfer of oxidants, contributing to the broader field of plasma-liquid applications for the mitigation of emerging contaminants.

Supporting executable scientific workflows in a clustered Infrastructure: DARIAH-IT and H2IOSC

Workflows have become essential in digital humanities, enabling the formalisation, automation and reproducibility of complex research processes. As the humanities increasingly adopt data-driven methodologies, workflows offer structured approaches to manage diverse data and tools while supporting transparency and collaboration. Recognising this need, DARIAH-IT has advanced research infrastructure development by focusing on workflow-based services within the H2IOSC (Humanities and Cultural Heritage Italian Open Science Cloud) project. DARIAH-IT leads the design and implementation of a national cloud system to support digital humanities research, ensuring interoperability, FAIR data practices and semantic integration across disciplines. Central to DARIAH-IT’s effort within H2IOSC is AEON (dAriah sErvice Oriented iNfrastructure), a platform that enables the creation, execution and management of scientific workflows. AEON integrates service provisioning, semantic validation and runtime orchestration, supporting reproducible research and collaborative practices.
