Membrane fusion is essential for the basal functionality of eukaryotic cells. In physiological conditions, fusion events are regulated by a wide range of specialized proteins, operating with finely tuned local lipid composition and ionic environment. Fusogenic proteins, assisted by membrane cholesterol and calcium ions, provide the mechanical energy necessary to achieve vesicle fusion in neuromediator...
Noble metal doping can achieve an increase in mass activity (MA) without sacrificing catalysis efficiency and stability, so that alkaline hydrogen evolution reaction (HER) performance of the catalyst can be optimized to the maximum degree. However, its excessively large ionic radius makes it difficult to achieve either interstitial doping or substitutional doping under mild conditions. Herein, a hierarchical...
Heterojunctions coupled into micro‐mesoscopic structures is an attractive strategy to optimize the light harvesting and carrier separation of semiconductor photocatalysts. A self‐templating method of ion exchange is reported to synthesize an exquisite hollow cage‐structured Ag2S@CdS/ZnS that direct Z‐scheme heterojunction photocatalyst. On the ultrathin shell of the cage, Ag2S, CdS, and ZnS with Zn‐vacancies...
This work reports a new form of tubular g‐C3N4 that is featured with a hierarchical core–shell structure introduced with phosphorous elements and nitrogen vacancies. The core is self‐arranged with randomly stacked g‐C3N4 ultra‐thin nanosheets along the axial direction. This unique structure significantly benefits electron/hole separation and visible‐light harvesting. A superior performance for the...
Ionic Crystals
In article number 2300743, Sayaka Uchida, Takashi Tachikawa, and co‐workers demonstrate a convenient method to obtain few‐atom silver clusters. Silver clusters with three, four, or six atoms emitting blue, green, or red colors are formed and stabilized in redox‐active porous ionic crystals (PICs). The cluster size is controlled by the degree of electron transfer from the PIC to silver...
H2O2‐fueled micromotors are state‐of‐the‐art mobile microreactors in environmental remediation. In this work, a magnetic FeOx@MnO2@SiO2 micromotor with multi‐functions is designed and demonstrated its catalytic performance in H2O2/peroxymonosulfate (PMS) activation for simultaneously sustained motion and organic degradation. Moreover, this work reveals the correlations between catalytic efficiency...
Eukaryotic cells have inner compartments (organelles), each with distinct properties and functions. One mimic of this architecture, based on biopolymers, is the multicompartment capsule (MCC). Here, MCCs in which the inner compartments are chemically unique and “smart,” i.e., responsive to distinct stimuli in an orthogonal manner are created. Specifically, one compartment alone is induced to degrade...
Lithium metal batteries (LMBs) are promising for next‐generation high‐energy‐density batteries owing to the highest specific capacity and the lowest potential of Li metal anode. However, the LMBs are normally confronted with drastic capacity fading under extremely cold conditions mainly due to the freezing issue and sluggish Li+ desolvation process in commercial ethylene carbonate (EC)‐based electrolyte...
With advances in cancer biology and an ever‐deepening understanding of molecular virology, oncolytic virus (OV)‐driven therapies have developed rapidly and become a promising alternative to traditional cancer therapies. In recent years, satisfactory results for oncolytic virus therapy (OVT) are achieved at both the cellular and organismal levels, and efforts are being increasingly directed toward...
Understanding and controlling the nucleation and crystallization in solution‐processed perovskite thin films are critical to achieving high in‐plane charge carrier transport in field‐effect transistors (FETs). This work demonstrates a simple and effective additive engineering strategy using pentanoic acid (PA). Here, PA is introduced to both modulate the crystallization process and improve the charge...
Using full solar spectrum for energy conversion and environmental remediation is a major challenge, and solar‐driven photothermal chemistry is a promising route to achieve this goal. Herein, this work reports a photothermal nano‐constrained reactor based on hollow structured g‐C3N4@ZnIn2S4 core–shell S‐scheme heterojunction, where the synergistic effect of super‐photothermal effect and S‐scheme heterostructure...
Bulk nanobubbles fascinate scientists because of their stability over long periods of time and their ability to carry gases, leading to numerous potential applications. Considering the hypoxic tumor microenvironment and the advantages of bulk nanobubbles, lipid‐encapsulated oxygen nanobubbles are prepared from free bulk oxygen nanobubbles in this study. The obtained carrier is then modified with a...
Authentication and verification of the most important government issued identity proof, i.e. passport has become more complex and challenging in the last few decades due to various innovations in ways of counterfeiting by fraudsters. Here, the aim is to provide more secured ink without altering its golden appearance in visible light. In this panorama, a novel advanced multi‐functional luminescent...
The application of carbides in catalysis, batteries, aerospace fields, etc. has been continuously expanded and deepened, which is attributed to the diversified physicochemical properties of carbides via a tune‐up of their morphology, composition, and microstructure. The emergence of MAX phases and high entropy carbides with unparalleled application potential undoubtedly further stimulates the research...
In this work, it is reported that large‐area (centimeter‐scale) arrays of non‐close‐packed polystyrene‐tethered gold nanorod (AuNR@PS) can be prepared through a liquid–liquid interfacial assembly method. Most importantly, the orientation of AuNRs in the arrays can be controlled by changing the intensity and direction of electric field applied in the solvent annealing process. The interparticle distance...
With the consumption of disposable electronic devices increasing, it is meaningful but also a big challenge to develop reusable and sustainable materials to replace traditional single‐use sensors. Herein, a clever strategy for constructing a multifunctional sensor with 3R circulation (renewable, reusable, pollution‐reducing biodegradable) is presented, in which silver nanoparticles (AgNPs) with multiple...
Catalytic Reactions
In article number 2207666, Xiaoguang Duan, Shaobin Wang, and co‐workers report on the application of well‐designated and multifunctional FeOx@MnO2@SiO2 micromotors as mobile microreactors for catalytic water purification. H2O2 is the fuel to generate oxygen bubble for propelling and peroxymonosulfate is the green oxidant to generate free radical species to realize the degradation...
A primary concern about photodynamic therapy (PDT) is its inability to regulate the generation levels of reactive oxidative species (ROS) based on the complex microenvironment, resulting in the impairment toward normal tissues and immunosuppression. Besides, tumor metastasis also compromises PDT's efficacy and drives mortality. However, it is very challenging to achieve such two goals within one nanosystem...
Perforated Carbon Nanotube Films
In article number 2300766, Run Shi, Kai Liu, and co‐workers report a large‐scale growth of uniform monolayer MoS2 by evenly distributing gas flows of precursors through a perforated carbon nanotube film. The as‐grown monolayer MoS2 shows quite good uniformity in geometry, density, structure, and electrical properties.
Ag clusters with a controlled number of atoms have received significant interest because they show size‐dependent catalytic, optical, electronic, or magnetic properties. However, the synthesis of size‐controlled, ligand‐free, and air‐stable Ag clusters with high yields has not been well‐established. Herein, it is shown that isostructural porous ionic crystals (PICs) with redox‐active polyoxometalates...
