Organic luminescent materials are indispensable in optoelectronic displays and solid‐state luminescence applications. Compared with single‐component, multi‐component crystalline materials can improve optoelectronic characteristics. This work forms a series of full‐spectrum tunable luminescent charge‐transfer (CT) cocrystals ranging from 400 to 800 nm through intermolecular collaborative self‐assembly...
Peptide assemblies are promising nanomaterials, with their properties and technological applications being highly hinged on their supramolecular architectures. Here, how changing the chirality of the terminal charged residues of an amphiphilic hexapeptide sequence Ac‐I4K2‐NH2 gives rise to distinct nanostructures and supramolecular handedness is reported.

Peptide Supramolecular Handedness
In article number 2304424, Hai Xu, Jun Yang, Jiqian Wang, and co‐workers report how changing the chirality of the terminal charged residues of an amphiphilic hexapeptide sequence Ac‐I4K2‐NH2 gives rise to distinct nanostructures and supramolecular handedness. The formation of wide nanotubes arises from the co‐assembly of right‐ and left‐handed β‐strands while thin,...
Extreme environments can cause severe harm to human health, and even threaten life safety. Lightweight, breathable clothing with multi‐protective functions would be of great application value. However, integrating multi‐protective functions into nanofibers in a facile way remains a great challenge. Here, a one‐step co‐electrospinning‐electrospray strategy is developed to fabricate a superhydrophobic...
Nanostructured transitional metal compounds (TMCs) have demonstrated extraordinary promise for high‐efficient and rapid lithium storage. However, good performance is usually limited to electrodes with low mass loading (≤1.0 mg cm−2) and is difficult to realize at higher mass loading due to increased electrons/ions transport limitations in the thicker electrode. Herein, the multi‐dimensional synergistic...
Fabrication of large‐area ionic covalent organic framework membranes (iCOMs) remains a grand challenge. Herein, the authors report the liquid water and water vapor‐assisted fabrication of large‐area superprotonic conductive iCOMs. A mixed monomer solution containing 1,3,5‐triformylphloroglucinol (TFP) in 1,4‐dioxane and p‐diaminobenzenesulfonic acid (DABA) in water is first polymerized to obtain a...
Photoelectricity‐Induced Artificial Synapses
A miniaturized diode with reversible switching state based on N‐n MoS2 homojunction uses a bandgap renormalization effect through the band alignment type regulated by both dielectric and polarization, controllably switched between type‐I and type‐II, which can be simulated as artificial synapse for sensing memory processing because of its rectification,...
The advent of big data era has put forward higher requirements for electronic nanodevices that have low energy consumption for their application in analog computing with memory and logic circuit to address attendant energy efficiency issues. Here, a miniaturized diode with a reversible switching state based on N‐n MoS2 homojunction used a bandgap renormalization effect through the band alignment type...
Tendon stem/progenitor cells (TSPCs) therapy is a promising strategy for enhancing cell matrix and collagen synthesis, and regulating the metabolism of the tendon microenvironment during tendon injury repair. Nevertheless, the barren microenvironment and gliding shear of tendon cause insufficient nutrition supply, damage, and aggregation of injected TSPCs around tendon tissues, which severely hinders...
The rational structural design of the electrode materials is significant to enhance the electrochemical performance for potassium ion storage, benefiting from the shortened ion diffusion distance, increased conductivity, and pseudo‐capacitance promotion. Herein, hydrated vanadium oxide (HVO) nanosheets with enriched oxygen defects are well confined into hollow mesoporous carbon spheres (HMCS), producing...

Second harmonic generation (SHG) of 2D crystals has been of great interest due to its advantages of phase‐matching and easy integration into nanophotonic devices. However, the polarization‐dependence character of the SHG signal makes it highly troublesome but necessary to match the laser polarization orientation relative to the crystal, thus achieving the maximum polarized SHG intensity. Here, it...
