Artificial solid electrolyte interphase in organic solutions is effective and facile for long‐cycling aqueous zinc ion batteries. However, the specific effects on different ionic environments have not been thoroughly investigated. Herein, pyromellitic acid (PA) are employed as organic ligand to coordinate with Zn2+ under various ionic environments. The connection between the ionic environment and...
Boosting charge separation and transfer of photoanodes is crucial for providing high viability of photoelectrochemical hydrogen (H2) generation. Here, a structural engineering strategy is designed and synthesized for uniformly coating an ultrathin CoFe bimetal‐organic framework (CoFe MOF) layer over a BiVO4 photoanode for boosted charge separation and transfer. The photocurrent density of the optimized...
An electrocatalyst composed of RuO2 surrounded by interfacial carbon, is synthesized through controllable oxidization‐calcination. This electrocatalyst provides efficient charge transfer, numerous active sites, and promising activity for pH‐universal electrocatalytic overall seawater splitting. An electrolyzer with this catalyst gives current densities of 10 mA cm−2 at a record low cell voltage of...
Liquid crystal (LC) emulsions represent a class of confined soft matter that exhibit exotic internal organizations and size‐dependent properties, including responses to chemical and physical stimuli. Past studies have explored micrometer‐scale LC emulsion droplets but little is known about LC ordering within submicrometer‐sized droplets. This paper reports experiments and simulations that unmask the...
Since the advent of graphene ushered the era of 2D materials, many forms of hydrogenated graphene have been reported, exhibiting diverse properties ranging from a tunable bandgap to ferromagnetic ordering. Patterned hydrogenated graphene with micron‐scale patterns has been fabricated by lithographic means. Here, successful millimeter‐scale synthesis of an intrinsically honeycomb‐patterned form of...
The ever‐increasing development of flexible and wearable electronics has imposed unprecedented demand on flexible batteries of high energy density and excellent mechanical stability. Rechargeable lithium (Li) metal battery shows great advantages in terms of its high theoretical energy density. However, the use of Li metal anode for flexible batteries faces huge challenges in terms of its undesirable...
Design of high‐performance all‐inorganic halide perovskites, especially lead‐free perovskites, is key to the broadening of its application prospects. Herein, the authors report the synthesis of ligand‐free cesium platinum (IV) bromide nanocrystals (Cs2PtBr6 NCs), a new kind of vacancy‐ordered lead‐free perovskite nanomaterial, by a facile one‐pot method. The Cs2PtBr6 NCs exhibits a narrow band gap...
Carbon‐based nanomaterials have been widely utilized in catalysis and energy‐related fields due to their fascinating properties. However, the controllable synthesis of porous carbon with refined morphology is still a formidable challenge due to inevitable aggregation/fusion of resulted carbon particles during the high‐temperature synthetic process. Herein, a hierarchically oriented carbon‐structured...
Two europium metal–organic frameworks (MOFs) based on the same ligand, named as ZJU‐23‐Eu and ZJU‐24‐Eu, are selectively synthesized by fine‐tuning solvent contents to tailor the coordination modes. Eu atoms are eight‐coordinated and nine‐coordinated in ZJU‐23‐Eu and ZJU‐24‐Eu respectively, and their frameworks vary in both spatial connectivity and symmetry. The ligand not only has multiphoton response...
High‐performance supercapacitors (SCs) are important energy storage components for emerging wearable electronics. Rendering low‐temperature foldability to SCs is critically important when wearable devices are used in a cold environment. However, currently reported foldable SCs do not have a stable electrochemical performance at subzero temperatures, while those that are performing are not foldable...
SnS2 has been widely studied as an anode material for sodium‐ion batteries (SIBs) based on the high theoretical capacity and layered structure. Unfortunately, rapid capacity decay associated with volume variation during cycling limits practical application. Herein, SnS2/Co3S4 hollow nanocubes anchored on S‐doped graphene are synthesized for the first time via coprecipitation and hydrothermal methods...
In article number 1801563, Bin Li, Guodong Qian, and co‐workers design the first example of using flexible metal–organic framework (MOF)‐based mixed‐matrix membranes (MMMs) as a fluorescent turn‐on sensor for the detection of hydrogen sulfide (H2S). The MMM sensor (70% MOF loading) shows a highly remarkable detection selectivity and sensitivity for H2S with a low detection limit around 92.31 × 10−9...
Metal–organic framework (MOF)–polymer mixed‐matrix membranes (MMMs) have shown great potential and superior performance in gas separations. However, their sensing application has not been fully established yet. Herein, a rare example of using flexible MOF‐based MMMs as a fluorescent turn‐on sensor for the detection of hydrogen sulfide (H2S) is reported. These MOF‐based MMMs are readily prepared by...
With extremely high specific capacity, silicon has attracted enormous interest as a promising anode material for next‐generation lithium‐ion batteries. However, silicon suffers from a large volume variation during charge/discharge cycles, which leads to the pulverization of the silicon and subsequent separation from the conductive additives, eventually resulting in rapid capacity fading and poor cycle...
Cathode buffer layers (CBLs) can effectively further the efficiency of polymer solar cells (PSCs), after optimization of the active layer. Hidden between the active layer and cathode of the inverted PSC device configuration is the critical yet often unattended vertical diffusion of the active layer components across CBL. Here, a novel methodology of contrast variation with neutron and anomalous X‐ray...
Exocytosis of single‐walled carbon nanotubes (SWCNTs) determines therapeutic efficiency and toxicity of nanoproducts but its underlying mechanism remains elusive. In this study, it is found that the exocytosis mechanism of SWCNTs is mediated mainly through the activation of P2X7 receptor (P2X7R), an ATP‐gated membrane receptor highly expressed in macrophages. Inhibition of P2X7R signaling by either...
The exocytosis and underlying mechanism of single‐walled carbon nanotubes (SWCNTs) in macrophages is revealed by B. Wan, L.‐H. Guo, and co‐workers on page 5998. Exocytosis of SWCNTs is initiated by the activation of the P2X7 receptor, which accounts for the lysosomal secretion pathway as a potential mechanism for cells to repel SWCNTs. The cover image shows microtubules providing orbits for the exocytosis...
