Embracing the politics of transformation: Policy action as “battle‐settlement events”

Review of Policy Research, EarlyView.
Abstract Societal transformations for addressing climate change are intensely contested and at risk of resistance and backlash to ambitious policy action. But they are frequently modeled through heuristics such as S‐curves which abstract from such conflicts, assuming increasing returns to scale as a driver of transformations.

Thermally Assisted Photocatalytic Hydrogen Production Using TiO₂/Cu: Evaluation of Performance and Stability

ChemCatChem, Volume 17, Issue 14, July 2025.
Thermal enhancement of TiO2/Cu photocatalysis boosts H2 production from 3,847 µmol g−1 h−1 at 40°C to 10,421 µmol g−1 h−1 at 70 °C. Elevated temperatures improve charge separation and reaction kinetics while maintaining catalyst stability. The synergistic photothermal approach demonstrates Cu/TiO2 as an efficient, noble‐metal‐free system for ...
