Bloch–Landau–Zener Oscillations in Moiré Lattices

Fortschritte der Physik, Volume 73, Issue 11, November 2025.
Abstract A theory of two‐dimensional Bloch–Landau–Zener (BLZ) oscillations of wavepackets in incommensurate moiré lattices under the influence of a weak linear gradient is developed. Unlike periodic systems, aperiodic lattices lack translational symmetry and therefore do not exhibit a conventional band‐gap structure.

Tuning Charge‐Separated State Lifetimes in Perovskite Nanocrystal‐Perylenediimide Hybrids

Advanced Optical Materials, Volume 13, Issue 28, October 2, 2025.
Functional perylenediimides with varied spacer lengths surface engineer CsPbBr₃ perovskite nanocrystals, yielding hybrid materials with new properties. Time‐resolved techniques reveal photoinduced charge separation from perovskite nanocrystals to perylenediimides, with microsecond‐lived charge carriers. Spacer length modulates charge carrier lifetimes,

Tunable Room‐Temperature Polaritons in the Very Strong Coupling Regime in Quasi‐2D Ruddlesden–Popper Perovskites

Advanced Optical Materials, Volume 13, Issue 30, October 24, 2025.
The study reports widely tunable room‐temperature exciton polaritons in quasi‐2D perovskite microcavities operating at the transition between strong and very strong coupling regimes. These experimental and theoretical insights explain the peculiar scaling behavior of the light–matter coupling in our tunable system, paving the way for future tunable ...

Host Cavities Enhance the Photocatalytic Conversion of α‐Terpinene to Ascaridole Under Visible‐Light Irradiation

Chemistry – A European Journal, Volume 31, Issue 55, October 1, 2025.
BODIPY‐functionalized host molecules are effective visible‐light photosensitizers for the conversion of α‐terpinene to ascaridole in the presence of molecular oxygen, providing up to a 28‐fold increase in the rate of conversion depending on the host employed.

Nutrients on the move: Investigating large scale fatty acid exports from European ponds via emerging insects

Limnology and Oceanography, Volume 70, Issue 10, Page 2844-2857, October 2025.
Abstract Permanent ponds are key landscape units that supply various ecosystem services. Notably, the export of aquatic subsidies to land via emerging insects may significantly influence terrestrial food webs. Polyunsaturated fatty acids (PUFA), which enhance consumer fitness, are among the essential exported components.

Insect visitation patterns in diploid Centaurea aspera and its related allotetraploid and triploid hybrids: Similar rates but distinct assemblages

American Journal of Botany, Volume 112, Issue 9, September 2025.
Abstract Premise Polyploidy is key to plant evolution by contributing to speciation, diversification, and adaptability. However, the minority cytotype exclusion effect can limit the persistence of polyploids, which can be mitigated by reproductive barriers such as distinct insect visitation between cytotypes. In eastern Spain, the diploid C.
