Advanced Solid Lubrication with COK‐47: Mechanistic Insights on the Role of Water and Performance Evaluation

Advanced Science, EarlyView.
This study is the first to report the solid lubrication performance of the newly discovered Ti‐based MOF (COK‐47) powder. COK‐47 exhibits a remarkably lowest and most stable coefficient of friction compared to typical solid lubricants. The lubrication mechanism involves water molecules from the air participating in tribochemical reactions, forming an ...

A Bias‐Tunable Multispectral Photodetector Based on a GaN/TexSe1‐x Homo‐Type Heterojunction with a Unidirectional Barrier

Advanced Science, EarlyView.
A bias‐tunable multispectral photodetector based on a TexSe1‐x/GaN homo‐type heterojunction with a unidirectional barrier is proposed. By modulating the bias polarity and magnitude, the device's spectral response range can be extended from UV to the SWIR region.

A Versatile Protein Scaffold Engineered for the Hierarchical Assembly of Robust and Highly Active Enzymes

Advanced Science, EarlyView.
This study introduces a self‐assembling protein scaffold engineered from Methanococcus jannaschii via disulfide bonds, enabling efficient in vivo assembly of bulky enzymes into helical structures without conjugation. Direct fusion increased the activity and thermostability of both monomeric and multimeric guest enzymes.

Correlations in Magnetic Sub‐Domains as an Unconventional Phase Diagram for van der Waals Ferromagnets

Advanced Science, EarlyView.
An unconventional magnetic order is observed in exfoliated CrBr3 layers, characterized by vertically correlated planar magnetic sub‐domains. Magnetic force microscopy, ab initio calculations, and micromagnetic simulations indicate that these sub‐domains arise from stacking faults modifying interlayer exchange coupling.

Direct Visualization and Quantitative Insights into the Formation and Phase Evolution of Cu Nanoparticles via In Situ Liquid Phase 4D‐STEM

Advanced Science, EarlyView.
By integrating in situ liquid phase transmission electron microscopy (LP‐TEM) with 4D scanning transmission electron microscopy (4D‐STEM), this work not only reveals the morphology and phase evolution of Cu nanoparticles during electrodeposition and electrooxidation processes but also demonstrates the possibility of mapping the grain size and phase ...
