X‐ray‐induced hydride formation in palladium nanowires in a gaseous hydrogen environment

open access: yesJournal of Applied Crystallography, EarlyView.
Powder diffraction is used to reveal X‐ray‐induced hydride formation in palladium nanowires in a gaseous hydrogen environment.Palladium hydrides are promising systems for hydrogen sensors and hydrogen storage, making the study of hydride formation in nanoparticles highly relevant. Lately, such studies have often been performed in situ or operando using

Dynamic sampling for SAXSTT: towards real‐time measurement adaptation

open access: yesJournal of Synchrotron Radiation, EarlyView.
A dynamic sampling strategy is presented to reduce the measurement time required for SAXS tensor tomography while maintaining reconstruction quality.Small‐angle X‐ray scattering tensor tomography (SAXSTT) is a powerful technique for non‐destructive 3D characterization of nanoscale structures by reconstructing q‐resolved reciprocal space maps.

Pollinator community composition and pollen resource use in calcareous grasslands under different landscape contexts across Europe

open access: yesJournal of Animal Ecology, EarlyView.
In this paper, we show that pronounced differences in pollinator communities exist between grasslands embedded in contrasting agricultural landscape contexts. Opportunistic foraging strategies of most pollinators resulted in large interaction turnover, but these shifts did not translate into major changes in overall network structure, most likely as a ...

Challenging Business Schools Through Subversive Performativity: The Potential of Art‐based Pedagogies

open access: yesBritish Journal of Management, EarlyView.
Abstract Business schools are often criticized for reproducing growth‐oriented norms, but alternative pedagogies remain difficult to normalize. Drawing on Butler's theory of subversive performativity, this study examines how art‐based pedagogy enables academics to challenge growth logics in business schools by transforming their identities over time ...

From talking tools to metahumans: social interaction, semiotic skill, and the authority of AI chatbots Des outils parlants aux métahumains : interactions sociales, compétences sémiotiques et autorité des robots conversationnels

open access: yesJournal of the Royal Anthropological Institute, EarlyView.
What does it take to turn a tool into a talking tool and that into an ultimate authority? Generative artificial intelligence (GenAI) in its diverse forms, such as large language models (LLMs), is celebrated as a useful tool. But LLM‐based conversational agents, or chatbots, the software applications through which ordinary users are likely to engage ...
