In article number 2004615, Inge K. Herrmann and co‐workers present cathodoluminescence‐based color immunotargeting enabling the localization of individual proteins along with full ultrastructural context. Cathodoluminescence electron microscopy using nanocrystal‐based molecular probes gives access to true color electron microscopy with nanometric resolution and offers a new route to assess structure‐function...
Inspired by the unique structure and lubrication mechanism of ball bearing, monodisperse, size‐uniform hydrogel spheres are fabricated by Hongyu Zhang, Xiangyang Xu, Wenguo Cui, and co‐workers in article number 2004519 using microfluidic technology, and subsequently modified with pSBMA to form superlubricated hydrogel microspheres using a one‐step bionic grafting approach. The superlubricated hydrogel...
Osteoarthritis, a lubrication dysfunction related disorder in joint, is characterized by articular cartilage degradation and joint capsule inflammation. Enhancing joint lubrication, combined with anti‐inflammatory therapy, is considered as an effective strategy for osteoarthritis treatment. Herein, based on the ball‐bearing‐inspired superlubricity and the mussel‐inspired adhesion, a superlubricated...
To unlock the great potential of lithium metal anodes for high‐performance batteries, a number of critical challenges must be addressed. The uncontrolled dendrite growth and volume changes during cycling (especially, at high rates) will lead to short lifespan, low Coulombic efficiency (CE), and security risks of the batteries. Here it is reported that Li metal anodes, employing the monodisperse, lithiophilic,...
Nanozymes are fundamentally interesting catalysts that are investigated as alternatives to fragile protein‐enzymes for applications in biotechnology, for prodrug activation, and use in biomedicine, as well as the catalysts that contributed to the Origin of Life. However, until now, nanozymes mostly have been documented to exhibit activity as red/ox catalysts, whereas examples of activity outside this...
N‐doped carbon‐encapsulated transition metal selenides (TMSs) have garnered increasing attention as promising electrocatalysts for hydrogen evolution reaction (HER). Accurately regulating the electronic structure of these nanohybrids to reveal the underlying mechanism for enhanced HER performances is still challenging and thus requires deep excavation. Herein, a series of pomegranate‐like NixSey@NC...
Multi‐metallic halides of group IA and IB metals are emerged as a new class of color tunable emitters. While chalcogenides and perovskites are extensively studied, these families of materials are little explored. In comparison, herein, lead and cadmium free bimetallic Cs‐Ag‐X (X = Cl, Br, I) halides are reported where the larger ion Ag+ helped in incorporating all the halide ions which in turn tune...
3D magnetic nanostructures are of great interest due to the possibility to design novel properties and the benefits for both technological applications such as high‐density data storage, as well as more fundamental studies. One of the main challenges facing the realization of these three‐dimensional systems is their fabrication, which includes the deposition of magnetic materials on 3D surfaces. In...
Although plenty of progress and achievements are made on hydrogel electrolyte researches, the inherent inferior low‐temperature performance of hydrogel electrolyte is still a severe challenge for wider application on the energy storage devices, due to the high content of water within hydrogel. Herein, an enhanced solar‐driven‐heating composite hydrogel electrolyte and a solar‐driven‐heating graphene...
Molybdenum sulfide emerged as promising hydrogen evolution reaction (HER) electrocatalyst thanks to its high intrinsic activity, however its limited active sites exposure and low conductivity hamper its performance. To address these drawbacks, the non‐equilibrium nature of pulsed laser deposition (PLD) is exploited to synthesize self‐supported hierarchical nanoarchitectures by gas phase nucleation...
Engineered DNA frameworks have been extensively exploited as affinity scaffolds for drug delivery. However, few studies focus on the rational design to comprehensively improve their stability, internalization kinetics, and drug loading efficiency. Herein, DNA framework‐based hybrid nanomaterials are rationally engineered by using a molecular docking tool, where the framework acts as a template to...
The aim of the present paper is to highlight a novel electrochemical assay for an extremely‐selective detection of fructose thanks to the use of a supramolecular complex between β‐cyclodextrins (β‐CDs) and a chemically modified ferrocene with boronic acid named 4‐Fc‐PB/natural‐β‐CDs. Another kind of β‐CDs, the 4‐Fc‐PB/3‐phenylboronic‐β‐CDs, is proposed for the detection of glucose. The novel electrochemical...
Despite their potential as a next‐generation alternative to current state‐of‐the‐art lithium (Li)‐ion batteries, rechargeable aqueous zinc (Zn)‐ion batteries still lag in practical use due to their low energy density, sluggish redox kinetics, and limited cyclability. In sharp contrast to previous studies that have mostly focused on materials development, herein, a new electrode architecture strategy...
To address the dendrite growth and interface instability of high‐capacity Li metal anode, heterogeneous seed‐decorated 3D host materials are expected to suppress the growth of Li dendrites. The physical stability and chemical reactivity of these nanoseeds are the decisive conditions for long cycling lithium metal batteries. Herein, carbon nanofibers decorated with uniform CrO0.78N0.48 nanoparticles...
Current research motivation on fabricating next‐generation lithium‐ion batteries by averting the growing demand for battery raw materials brings enormous interest on the V2O5 cathode again as a result of its abundance, ease synthesis, and tunable Li‐intercalation properties. So far, the research activities are mainly focused on V2O5 to attain a maximum capacity (>300 mAh g−1) for more than 1 mol...
Micro/nanoscaled motor particles represent a group of intelligent materials that can precisely and rapidly respond to biological microenvironments and improve therapeutic outcomes. In order to maximize biomedical application potentials, developing a nanoscaled motor particle that is able to move autonomously toward a biological target is highly desired but still remains a critical challenge. Herein,...
For the first time Janus‐like films of surface‐acylated cellulose nanowhiskers (CNWs) with or without graphene oxide (GO) via one‐step evaporation‐driven self‐assembly process are reported, which have reconstructible time‐dependent micro‐/nanostructures and asymmetric wettability. The heterogeneous aggregation of CNWs on rough Teflon substrates favors the formation of uniform films, leading to hydrophobic...
In article number 2002837, Sang‐Young Lee and co‐workers present a 3D bicontinuous heterofibrous network scaffold (HNS), consisting of single‐walled carbon nanotubes and cellulose nanofibers as a new electrode architecture for rechargeable aqueous ZnMnO2 batteries. The HNS allows the formation of bicontinuous electron/ion conduction pathways, thereby facilitating the redox kinetics of MnO2. Consequently,...
