US Foreign Policy and the Gulf States: Changing Dynamics in a Multipolar World

open access: yesWorld Affairs, Volume 188, Issue 4, Winter 2025.
ABSTRACT This article focuses on US foreign policy toward the Gulf from Obama's Pivot to Asia to the initial period of the second Trump administration. It situates the role of the US within the broader context of the global energy transition and the Gulf states as geopolitical actors in a multipolar world order.

Lost Opportunities in Sustainable Hydropower: The Overlooked Role of Sediment Management and Coordinated Dam Operations

open access: yesEarth's Future, Volume 13, Issue 12, December 2025.
Abstract Balancing hydropower development with river sediment connectivity is essential for meeting energy demands while mitigating impacts on river ecosystems and delta communities. Here, we introduce an integrated modeling framework to jointly explore water and sediment release strategies alongside dam planning, addressing the complex interplay ...

Across the edge: Spatial segregation drives community structure in tri‐trophic multilayer networks at a forest–grassland edge

open access: yesJournal of Animal Ecology, Volume 94, Issue 11, Page 2205-2219, November 2025.
This study reveals how forest–grassland edges act as ecological barriers that shape tri‐trophic interaction networks. Using multilayer network theory, it uncovers how species influence and biodiversity patterns emerge across spatial layers, offering novel insights into edge‐driven community assembly and conservation in fire‐prone mosaics.

The Oxidized Ti2(Al/Sn)C Behavior as Anode for Lithium‐ and Sodium‐Ion Batteries: The Role of the MAX Phase Order

open access: yesChemElectroChem, Volume 12, Issue 19, October 3, 2025.
The present study is dedicated to investigation of the performance of oxidized Ti2(Al/Sn)C system (211 MAX phases) as anode for lithium and sodium ion batteries. Their behavior has been rationalized as function of the tin content and as function of the MAX phase order, with detailed comparison with the 312 MAX phase analog series.

Iridium Oxide Shell Structure on Rutile Titanium Oxide for Efficient Supported Catalyst for the Oxygen Evolution Reaction

open access: yesAdvanced Science, Volume 12, Issue 39, October 20, 2025.
Core–shell and decorated iridium oxide on titanium oxide are formed on spherical supports designed. The core–shell material presents performance similar to that of unsupported materials and does not present the electronic limitations usually present for supported materials with non‐conductive supports.

Interactions of rare earth elements with living organisms and emerging biotechnical applications

open access: yesPLANTS, PEOPLE, PLANET, Volume 7, Issue 5, Page 1251-1274, September 2025.
Rare earth elements (REEs) are critical resources required to achieve net‐zero carbon emission targets and energy security. However, rising demand for REEs coupled with significant extraction and processing challenges and geopolitical risks restricts access to REE resources.

Gill evolution in Neotropical electric fishes: Comparative phylogenetic evidence for hypoxia‐driven adaptation

open access: yesFunctional Ecology, Volume 39, Issue 8, Page 1940-1956, August 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Tropical freshwater fishes are often exposed to hypoxia, which limits aerobic metabolism and drives the evolution of diverse physiological, behavioural and morphological adaptations.

Institutions, in time: Designing feedback pathways for shared infrastructure transitions

open access: yesPolicy Studies Journal, Volume 53, Issue 3, Page 654-680, August 2025.
Abstract Electric utilities, challenged by a rapidly unfolding energy transition, use many informal institutions to bridge across technologies and sectors. Little is known, however, about how electric utility systems and other polycentric systems' institutions‐in‐use vary and evolve over time.
