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

Earth'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

Journal 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

ChemElectroChem, 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

Advanced 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.
