Ion Crowding Effect in Unilaterally Downsized Perovskite Memristors

open access: yesAdvanced Science, EarlyView.
The downscaling of perovskite memristors incorporating monocrystalline nanoplates is accompanied by an ion crowding effect, which greatly enhances the local electric field in the vicinity of electrode. The highly controlled crowding of anions and vacancies results in anisotropic switching characteristics as well as unique morphology modification ...

Enhanced Energy Transfer from a Metal–Organic Framework to a Highly Confined Organic Phosphorescent Dye

open access: yesAdvanced Science, EarlyView.
A phosphorescent dye was designed to fit in a hand‐to‐glove fashion into the 1D‐pore channels of MIL‐68(In). We synthesized MIL‐68(In) as powder and thin films, loaded the dye into the pores with controlled packing, and found that the phosphorescence and quantum yield are enhanced.

In Situ Electrochemical Activation of Pseudo‐Layered NbS3 via Interlayer Expansion and Dual Redox for High Mg‐Ion Storage

open access: yesAdvanced Science, EarlyView.
A quasi‐1D pseudo‐layered NbS3 cathode for magnesium‐ion batteries can be created through electrochemically induced interlayer expansion. The widened ion‐transport channels enable fast magnesium ion diffusion and unlock coupled cationic‐anionic redox chemistry.

Monolithic UV‐Laser Programming of Photothermally Meta‐Morphing SMA Structures: Dual‐Encoded Kirigami Mechanics and Photonic Absorbance

open access: yesAdvanced Science, EarlyView.
A monolithic manufacturing strategy is presented for photothermal shape memory alloy (SMA) meta‐morphing structures. Using a single‐step UV‐laser process, the mechanical compliance is programmed via kirigami patterning while optical absorbance is simultaneously tuned through surface oxidation.

Redox‐Active Tungsten Mono‐Oxo Bis(dithiolene) Complex: A Fast‐Rechargeable Anode for High‐Capacity Lithium‐Ion Batteries

open access: yesAdvanced Science, EarlyView.
This study reports the first application of a W‐oxo bis(dithiolene) complex, (Et4N)2[WO(S2C2(C6H5)2)2], as a novel anode material for lithium‐ion batteries. This complex stores Li+ ions via multivalent W‐centered redox processes involving its oxo (WO) and dithiolene (S) sites.
