Exploring the exploration: implications of leaving or remaining at the natal site during the early stages of independence in a partially migratory bird

Ibis, EarlyView.
Despite being an important fraction of any animal population, juveniles are a severely understudied group. Juveniles often need to learn an array of skills that allow them to survive independently and do so while undertaking decisions that may impact their fitness, recruitment and survival, having therefore relevant demographic implications.

Advancing Circular Strategies in Photovoltaics: Assessing Reuse Readiness Across Technical, Economic, and Environmental Dimensions in a Case Study

Progress in Photovoltaics: Research and Applications, Volume 34, Issue 9, Page 1077-1099, September 2026.
This study examines the reuse readiness of photovoltaic modules through the Swiss PV Circle project. Results confirm technical feasibility with cost savings from targeted preselection, whereas economic viability depends on module age, testing, and market conditions.

Regulating Ligand‐to‐Metal Charge Transfer in UiO‐66(Zr)‐NH2 With Site‐Isolated Cu+ Centers for Efficient Photocatalytic H2O2 Generation

Small Science, Volume 6, Issue 8, August 2026.
Incorporation of highly dispersed Cu species into UiO‐66(Zr)‐NH2 introduces a competing ligand‐to‐Cu charge–transfer pathway that suppresses charge recombination and enhances photocatalytic H2O2 production. Combined PL, TRPL, TRIR, and variable‐temperature FTIR analyses reveal Cu‐mediated modulation of excited‐state dynamics and oxygen reduction ...
