Archaeological Prospection, EarlyView.ABSTRACT Medieval and early modern drowned villages in the intertidal zone of the Scheldt estuary (the Netherlands) constitute intriguing yet largely understudied components of north‐western Europe's underwater cultural heritage. Despite their high archaeological potential as time capsules of past settlement landscapes, research has remained limited ...

Batteries &Supercaps, Volume 8, Issue 3, March 2025.A novel and comprehensive 3D‐resolved kinetic Monte Carlo model coupled with mean square displacement analysis is introduced. This computational approach allows to explore, for the first time, the concentration and the state of charge effects on ionic diffusion coefficient and viscosity in methyl viologen‐based electrolytes used in organic redox flow ...

Business Strategy and the Environment, EarlyView.ABSTRACT Despite more than 20 years of research into sustainable tourism, the environmental impact of the UK hospitality sector remains high. A growing body of research into the concept of a circular economy (CE) demonstrates that transitioning to this way of working has significant benefits both for the environment and business outcomes.

Business Strategy and the Environment, EarlyView.ABSTRACT Circular ecosystems connect diverse actors who collaborate to close resource loops and pursue sustainable goals without centralized control. Such arrangements entail heightened interdependence and uncertainty, making trust, understood as the willingness to accept vulnerability based on positive expectations of others' behavior, a critical ...
