Stabilising Routines in Complex Emergencies: How Basic Service Continuity Shapes Perceived Security

open access: yesPublic Administration and Development, EarlyView.
ABSTRACT This study examines how locally embedded actors describe the relationship between basic service continuity and perceived security in complex emergencies, with particular attention to the stabilisation of everyday routines. Using Proximity‐Predictability‐Attributability (PPA) as an analytic lens, we trace how interviewees relate access to water,

An Ultrafast Charge-Driven Topological Intercalation Prelithiation Strategy for Carbon-Silicon Composite Anodes. [PDF]

open access: yesAdv Sci (Weinh)
In this work, an ultrafast topological intercalation prelithiation method capable of forming a uniformly 3D stable solid electrolyte interface (SEI) network on porous C/SiOx nanofiber anodes within mere 30 s is designed. The SEI significantly enhances the initial Coulombic efficiency of the anodes to 99.44%, and the corresponding batteries show a ...

Test Procedures for the Evaluation of the Performance and Stability of Direct Ammonia Fuel Cells

open access: yesEnergy Technology, Volume 14, Issue 7, July 2026.
A comprehensive electrochemical test protocol for direct ammonia fuel cells (DAFCs) is introduced, combining static, dynamic, and open‐circuit load regimes with three‐electrode operation to deconvolute anode and cathode contributions. Voltage decay is shown to be dominated by reversible anode deactivation driven by fuel depletion, with full performance

Dynamic Testing of Cold Gas Sprayed Bipolar Plates–Porous Transport Layer Coating System in Proton Exchange Membrane Water Electrolysis

open access: yesAdvanced Engineering Materials, Volume 28, Issue 11, 3 June 2026.
Through direct application of porous transport layer (PTL) on the bipolar plate (BPP) with thermal spraying, the interfacial contact resistance is improved. With the cold gas sprayed BPP–PTL coating system, a proton exchange membrane water electrolysis cell with a cell voltage of Ucell = 1.9 V can be operated up to i = 2.5 A/cm2 in a dynamic mode ...
