2D Ruddlesden–Popper (RP) perovskites have been intensively investigated due to their superior stability and outstanding optoelectrical properties. However, investigations on 2D RP perovskites are mainly focused on A‐site substituted perovskites and few reports are on X‐site substituted perovskites especially in X‐ray detection field. Here, X‐site substituted 2D RP perovskite Cs2Pb(SCN)2Br2 polycrystalline...
Solar Steam Generation
In article number 2204898, Dan Liu, Weiwei Lei, and co‐workers report a viable and general method that allows an effective synthesis of transition metal dichalcogenides (TMDs)‐O‐doped graphene nanosheet heterostructures by utilizing commercial TMD powder and sucrose as precursors. The solar evaporators of WS2‐O‐graphene exhibit high‐performance water evaporation due to the improved...
Two‐dimensional (2D) transition metal dichalcogenides and graphene have revealed promising applications in optoelectronic and energy storage and conversion. However, there are rare reports of modifying the light‐to‐heat transformation via preparing their heterostructures for solar steam generation. In this work, commercial WS2 and sucrose are utilized as precursors to produce 2D WS2‐O‐doped‐graphene...
A booming demand for wearable electronic devices urges the development of multifunctional smart fabrics. However, it is still facing a challenge to fabricate multifunctional smart fabrics with satisfactory mechanical property, excellent Joule heating performance, highly efficient photothermal conversion, outstanding electromagnetic shielding effectiveness, and superior anti‐bacterial capability. Here,...
Understanding the direct interaction of nanostructures per se with biological systems is important for biomedical applications. However, whether nanostructures regulate biological systems by targeting specific cellular proteins remains largely unknown. In the present work, self‐assembling nanomicelles are constructed using small‐molecule oleanolic acid (OA) as a molecular template. Unexpectedly, without...

In article number 2205531, Ke‐Wu Zeng and co‐workers describe the natural product oleanolic acid‐based self‐assembling nanostructures specially bind to proteasome subunit alpha 6 (PSMA6) to activate proteasome for cancer cell pyroptosis. This study opens up a new direction for the development anti‐cancer nanomedicine from natural resources.
Higher‐metal (HM) nitrides are a fascinating family of materials being increasingly researched due to their unique physical and chemical properties. However, few focus on investigating their application in a solar steam generation because the controllable and large‐scale synthesis of these materials remains a significant challenge. Herein, it is reported that higher‐metal molybdenum nitride nanosheets...
Potassium‐ion batteries (PIBs) are recognized as promising alternatives for lithium‐ion batteries as the next‐generation energy storage systems. However, the larger radius of K+ hinders the K+ insertion into the conventional carbon electrode and results in sluggish potassiation kinetics and poor cycling stability. Here, nitrogen and fluorine dual doping of soft carbon nanotubes (NFSC) anode are synthesized...
The additive strategy is widely used in optimizing the morphology of organic solar cells (OSCs). The majority of additives are liquid with high boiling points, which will be trapped within device and consequently deteriorate performance during operation. In this work, solid but volatile additives 2‐(4‐fluorobenzylidene)‐1H‐indene‐1,3(2H)‐dione (INB‐F) and 2‐(4‐chlorobenzylidene)‐1H‐indene‐1,3(2H)‐dione...
The unique feature of nacre‐like 2D layered materials provides a facile, yet highly efficient way to modulate the transmembrane ion transport from two orthogonal transport directions, either vertical or horizontal. Recently, light‐driven active transport of ionic species in synthetic nanofluidic systems attracts broad research interest. Herein, taking advantage of the photoelectric semiconducting...
Silicon holds great promise as an anode material for lithium‐ion batteries with higher energy density; its implication, however, is limited by rapid capacity fading. A catalytic growth of graphene cages on composite particles of magnesium oxide and silicon, which are made by magnesiothermic reduction reaction of silica particles, is reported herein. Catalyzed by the magnesium oxide, graphene cages...
Electrocatalytic hydrogen evolution reaction (HER) based on water splitting holds great promise for clean energy technologies, in which the key issue is exploring cost‐effective materials to replace noble metal catalysts. Here, a sequential chemical etching and pyrolysis strategy are developed to prepare molybdenum carbide‐decorated metallic cobalt@nitrogen‐doped porous carbon polyhedrons (denoted...
In the information age, it is important to protect the security and integrity of the information. As a result, the fluorescent ink as an antifake technology and the fingermark as an information carrier have aroused great interest. In this work, highly water‐soluble lanthanide (Ln3+)‐doped tetragonal phase (t‐) LaVO4 nanoparticles (NPs) are successfully obtained via a simple, fast, and green microwave‐assisted...
The conjugate of paclitaxel (PTX) and docosahexaenoic acid has entered into clinical trials. However, the most recent clinical outcomes fell short of expectations, due to the extremely slow drug release from the hydrophobic conjugates. Herein, a novel prodrug‐based nanoplatform self‐assembled by the disulfide bond linked conjugates of PTX and oleic acid for rapid and differential release of PTX in...
For the large‐area fabrication of thin‐film transistors (TFTs), a new conjugated polymer poly[9‐(1‐octylonoyl)‐9H‐carbazole‐2,7‐diyl] is developed to harvest ultrahigh‐purity semiconducting single‐walled carbon nanotubes. Combined with spectral and nanodevice characterization, the purity is estimated up to 99.9%. High density and uniform network formed by dip‐coating process is liable to fabricate...
