A New Strategy for Creating Quantum Light Emitters Via Post‐Growth Hydrogen‐Ion Irradiation of III‐V Nanowires

Advanced Functional Materials, EarlyView.
A post‐growth method is demonstrated to realize energy‐tunable quantum emitters in GaAs/GaAsN/GaAs core–multishell nanowires on a Si substrate. By combining the N‐induced bandgap reduction with H‐ion irradiation, the GaAsN potential landscape is engineered, enabling isolated, narrow emission lines that function as single‐photon sources with g(2)(0) ∼ 0.

Climate change exacerbates residential radon exposure and lung cancer risk

Communications Sustainability
Climate change adaptation strategies, such as increased air conditioning use, greater time spent indoors, and seeking cooler lower-floor spaces, may inadvertently increase residential radon exposure and associated lung cancer risk. We conducted a scoping

Halide Composition Controls Phase Morphology and Device Specific Performance in Perovskite Photovoltaics and Light Emitting Diodes

Advanced Functional Materials, EarlyView.
We demonstrate that halide composition determines phase morphology, governing distinct operating mechanisms in mixed halide perovskites. Phase segregating 75% Br compositions enhance solar cell performance, whereas intrinsically phase‐separated 95% Br compositions provide stable light emitting diodes.

Stabilization of Strongly Reduced Fe(I) Single Atom Species Coordinated in a 2D Self‐Assembled Metal–Organic Network

Advanced Functional Materials, EarlyView.
A graphene‐supported 2D metal–organic network stabilizes highly reactive Fe(I)‐N4 single sites through Co‐induced charge redistribution. Combined experiments and theory reveal Fe(I) formation, oxygen‐driven oxidation, and O2 activation mechanisms, offering a strategy to access low‐valent iron centers relevant to catalytic and biological processes ...

Decoupling Li+ Transport in Self‐Healing Polymer Dual‐Salt Electrolytes for Room Temperature Lithium Metal Batteries

Advanced Functional Materials, EarlyView.
A self‐healable polymer matrix, crosslinked via dynamic imine bonds, is synergistically coupled with a LiPF6–LiDFOB dual‐salt system to decouple Li+ from the polymer matrix, enabling fast Li+ transport. This strategy offers an effective pathway toward high‐performance, next‐generation gel‐polymer‐based Li‐metal batteries.
