ABSTRACT Extracellular vesicle therapies have been developed for tissue repair, but how donor‐cell senescence reshapes vesicle‐mediated mitochondrial transfer remains unclear. Here, we show that senescent adipose‐derived stem cells (ADSCs) redirect damaged mitochondria into microvesicles (MVs), converting protective vesicles into pro‐degenerative ...

New methods for the speciation analysis of radioactive iodine in aqueous samples
Radioactive iodine in the environment comes both from nature and as a result of human activities. Understanding its behavior and fate in the environment, to enable assessment be made of its environmental impact, requires knowledge of its chemical form ...

Photoelectrocatalytic Diazidation of Olefins via Synergistic Dual Iron Species
We report a simple and general approach for 1,2‐diazidation of alkenes by a photoelectrochemical strategy using TMSN3 as an azide source. This transformation proceeds using earth‐abundant iron under mild reaction conditions. It displays broad functional group compatibility and accommodates diverse alkene types‐including unactivated, activated, electron‐

Highly Linear Perovskite Synapses for Neuromorphic Computing
Voltage spikes applied to an Au/ACI‐phase perovskite/ITO memristor emulate the ionic signaling of a biological synapse, generating a tunable postsynaptic current. The vertically aligned perovskite film confines iodide‐vacancy migration, enabling highly linear, and symmetric conductance updates with 100 states and 5.5 aJ per event. Such synapses sustain

Anion‐Cation Synergistic Passivation for High‐Performance FA‐Cs Halide Perovskite Photodetectors
An anion‐cation synergistic passivation strategy is developed to improve perovskite photodetectors. Surface‐localized DMePDA2+ cations and bulk‐diffused Cl− anions simultaneously reduce defects, enhancing charge transport and suppressing recombination.

Eco‐Friendly Laser‐Induced Graphene/Perovskite Hybrids for Eco‐Friendly Photodetectors
A sustainable paper‐based photodetector was developed by combining laser‐induced graphene (LIG) with MAPbI3 perovskite. Compared with pure LIG devices, the hybrid photodetector exhibited nearly 10‐fold higher responsivity and 7‐fold greater detectivity while maintaining stable performance after 1000 bending cycles, demonstrating its potential for ...

Maximum Stability Point Tracking Stabilizes Wide‐Bandgap Mixed‐Halide Perovskite Solar Cells
A maximum stability point tracking (MSPT) strategy suppresses charge trapping‐induced halide segregation, enabling wide‐bandgap perovskite solar cells to achieve significantly enhanced operational stability compared to conventional maximum power point tracking (MPPT).

Perovskite/silicon tandem solar cells exhibit outstanding efficiencies; however, the development of scalable and high‐throughput manufacturing processes remains a critical challenge. Here, we demonstrate accelerated deposition of multiple functional layers via high‐rate thermal evaporation without compromising film quality or device performance.

Non‐Buckling Stacks of Nanocarbon Molecules
A nanometer‐sized nanocarbon molecule with a central octagon was synthesized by optimizing a tetrameric macrocyclization via concentration‐dependent yield analysis (CYAN). The slightly contorted molecular structure was found to be frozen in a dimeric stack in solution, whereas dissociation into monomers liberated the molecule to undergo buckling ...
