Synthetic Control of Water‐Stable Hybrid Perovskitoid Semiconductors

open access: yesAdvanced Materials, EarlyView.
Hybrid metal‐halide perovskites are promising semiconductors for optoelectronics, yet their water stability is problematic. A new synthesis method is developed using lead iodide and cysteamine under various pH conditions, forming stable perovskitoid structures.

Fatigue‐Resistant Mechanoresponsive Color‐Changing Hydrogels for Vision‐Based Tactile Robots

open access: yesAdvanced Materials, EarlyView.
Mechanoresponsive color‐changing materials that can reversibly and resiliently change color in response to stress are highly desirable for diverse technologies in optics, sensors, and robots; however, such materials are rarely achieved. This work reports a fatigue‐resistant mechanoresponsive color‐changing hydrogel that exhibits reversible, resilient ...

Optimizing Perovskite Surfaces to Enhance Post‐Treatment for Efficient Blue Mixed‐Halide Perovskite Light‐emitting Diodes

open access: yesAdvanced Materials, EarlyView.
The halide postdeposition process is optimized by engineering blue mixed‐halide 3D perovskites with acetate‐rich surfaces. This engineered perovskite minimizes the washing effect of isopropanol, which slows down surface reconstruction and ultimately promotes the formation of a uniform mixed‐halide perovskite phase.
