The source‐to‐sea nexus between water and ocean law: An international and EU perspective

open access: yesReview of European, Comparative &International Environmental Law, Volume 35, Issue 1, Page 210-224, April 2026.
Abstract The source‐to‐sea (S2S) approach provides a systemic framework for analysing the governance of naturally interconnected freshwater and marine ecosystems. This paper examines the extent to which the S2S approach is reflected in key international and EU water and ocean law instruments, as well as the legal and governance implications of said ...

Promoting Electrochemical Reactions with Dual‐Atom Catalysts for High‐Rate Lithium–Sulfur Batteries

open access: yesAdvanced Materials, Volume 38, Issue 2, 8 January 2026.
A scalable strategy for synthesizing transition metal–bismuth atomic pairs on carbon nitride to accelerate sulfur redox reactions in lithium–sulfur batteries is presented. Nickel‐bismuth and cobatl‐bismuth catalysts improve rate performance by promoting direct electrochemical transitions and rapid Li2S nucleation, minimizing sulfur loss, and enhancing ...
