Radical‐Polar Crossover Bicyclization Enables a Modular Synthesis of Saturated Bicyclic Amines

open access: yesAdvanced Science, EarlyView.
Herein, we report the successful realization of a radical‐polar crossover bicyclization reaction from easily available cyclopropylamines and substituted alkenes through photoredox catalysis. This approach introduces an innovative methodology for the de novo synthesis of a diverse collection of 4/5‐, 5/5‐, 6/5‐,7/5‐ and 5/6‐fused saturated bicyclic ...

Ambipolar Charge Transport in Perovskite CsPbBr3 γ‐Ray Detectors with Superior Uniformity and Spectral Resolution by Zone Refining Processing

open access: yesAdvanced Science, EarlyView.
Zone refining processing has been proposed to achieve ultrahigh purity level in perovskite CsPbBr3 crystals, enabling ambipolar charge transport by enhancing the electron transport properties, thereby resulting in better γ‐ray detector performance with exceptional uniformity and reproducibility.

A Nanostructured Ru‐Mn‐Nb Alloy with Oxygen‐Enriched Boundaries for Ampere‐Level Hydrogen Evolution

open access: yesAdvanced Science, EarlyView.
Ru62Mn12Nb21O5 medium‐entropy alloy with a crystal‐crystal dual‐phase structure is deposited on a carbon cloth substrate by the magnetron sputtering method. The oxygen‐rich interface induced by the rich Mn phase and the poor Mn phase optimized the electronic structure of the catalyst, adjusted the adsorption and desorption processes of intermediates ...

Fast pH‐Driven Solubilization Method of Realgar (As4S4) to Reduce the Toxicity of Arsenic [As(III)] for Medicinal Purposes

open access: yesAdvanced Science, EarlyView.
Arsenic trioxide transformed acute promyelocytic leukemia therapy and shows promise against HIV. A new method to solubilize the mineral realgar produces different arsenic species depleting the main arsenic target, nuclear PML protein, and retaining effects on leukemic and HIV reservoir cells, while minimizing off‐target damage.
