Halide‐Exchange Arrest Enables Reabsorption‐Free CsPbCl3/CsPbI3 Perovskite Core/Shell Nanocrystals

Advanced Science, EarlyView.
Achieving large Stokes shifts in perovskite nanocrystals is challenging due to halide mobility that disrupts stable core–shell structures. Using CdCl2 passivation, this work stabilizes CsPbCl3/CsPbI3 heterostructures, yielding a ≈1.2 eV Stokes shift, high quantum yield, and fast exciton transfer, enabling reabsorption‐free emitters for advanced ...

Lattice Carbon‐Mediated Ultralow‐Barrier C–C Coupling for Selective CO Electroreduction to Ethylene

Advanced Science, EarlyView.
Combined DFT and molecular dynamics simulations reveal that while the lattice carbon at the MXene edge cannot directly bind CO2 to form ethylene, it acts as an active center to promote C─C coupling between adjacent *CO intermediates for ethylene production.

Does urban shrinkage require urban policy? The case of a post-industrial region in Poland

Regional Studies, Regional Science, 2020
The problem of depopulation in towns is present in most European countries. In Central and Eastern Europe it emerged primarily after the political transformation at the turn of the 1980s and 1990s.

Synergetic Lattice and Surface Engineering: Stable High‐Voltage Cycle Performance in P3‐Type Layered Manganese Oxide

Advanced Energy Materials, EarlyView.
A dual lattice‐surface strategy employing NaTi2(PO4)3 is adopted to enhance the performance of P3‐type Na0.67[Zn0.3Mn0.7]O2, whereby Ti stabilizes the bulk lattice and surface P species mitigate degradation, collectively improving high‐voltage cycling stability, Na+ diffusion, and oxygen redox reversibility through synergistic structural and ...

Nuclear Spin Dynamics of Ionized Phosphorus Donors in Silicon

, 2012
We demonstrate the coherent control and electrical readout of the nuclear spins of ionized phosphorus donors in natural silicon. By combining pulsed illumination with coherent electron spin manipulation, we selectively ionize the donor depending on its ...

Women and the Rural World. The Reasons Put Forward by Women As to Why the Population Continues to Fall in Many Parts of Andalusia (Spain)

European Countryside
In Europe today, depopulation affects not only rural but also some urban areas, albeit with greatly varying intensity. Andalusia is no exception. After describing its striking territorial differences, this article analyses women’s opinions about the ...
