State‐of‐the‐Art, Insights, and Perspectives for MOFs‐Nanocomposites and MOF‐Derived (Nano)Materials

open access: yesAdvanced Materials, EarlyView.
Different approaches to MOF‐NP composite formation, such as ship‐in‐a‐bottle, bottle‐around‐the‐ship and in situ one‐step synthesis, are used. Owing to synergistic effects, the advantageous features of the components of the composites are beneficially combined, and their individual drawbacks are mitigated.

Probing and Tuning Strain‐Localized Exciton Emission in 2D Material Bubbles at Room Temperature

open access: yesAdvanced Materials, EarlyView.
This work provides an approach: 1) to directly visualize the associated exciton properties, revealing an intrinsic emission wavelength shift, and 2) actively modify local strain, enabling further exciton emission tuning. These findings provide direct insights into the strain‐localized emission dynamics in bubbles and establish a robust framework for ...

Micro‐Strain Responsive Near‐Infrared Mechanoluminescence for Potential Nondestructive Artificial Joint Stress Imaging

open access: yesAdvanced Materials, EarlyView.
In situ and real‐time stress sensing during total knee replacement procedure is expected to be realized based on near‐infrared mechanoluminescent phosphor of Sr3Sn1.98Sb0.02O6.99, which has the lowest strain sensitivity as low as 50 µst. Abstract Recently, joint replacement surgery is facing significant challenges of patient dissatisfaction and the ...

Li‐Well ZnO Memtransistors: High Reliability for Neuromorphic Applications

open access: yesAdvanced Materials, EarlyView.
A novel lithium (Li)‐well ZnO memtransistor integrates transistor switching and nonvolatile memory, akin to ferroelectric field‐effect transistors (FeFETs) and floating gates, while enabling low‐power operation via Li⁺ ion migration. Li⁺ ion migration and switching mechanisms were confirmed by 3D secondary ion mass spectrometry (SIMS).

Spatially‐Controlled Planar Guided Crystallization of Low‐Loss Phase Change Materials for Programmable Photonics

open access: yesAdvanced Materials, EarlyView.
The concept of spatially‐controlled planar guided crystallization is a novel method for programming the growth of optically homogeneous low‐loss Sb2S3 phase‐change material (PCM), leveraging the directional crystallization within confined channels.
