In article number 2003816, Lei Li and co‐workers implement a proof‐of‐concept solution‐processed all‐V2O5 battery with symmetrical electrode structure. The electrodes are prepared via the solution‐processed method, indicated by the river with the boat. V2O5 works as both cathode and anode. The storage/release charges via Li+ intercalation/de‐intercalation in V2O5 like the balanced mutual transformation...
Environmentally friendly ZnSe/ZnS core/shell quantum dots (QDs) as an alternative blue emission material to Cd‐based QDs have shown great potential for use in next‐generation displays. However, it remains still challenging to realize a high‐efficiency quantum dot light‐emitting diode (QLED) based on ZnSe/ZnS QDs due to their insufficient electrical characteristics, such as excessively high electron...
Electromagnetic (EM) wave absorption materials have attracted considerable attention because of EM wave pollution caused by the proliferation of electronic communication devices. One‐dimentional (1D) structural magnetic metals have potential as EM absorption materials. However, fabricating 1D core–shell bimetallic magnetic species is a significant challenge. Herein, 1D core–shell bimetallic magnetic...
Dispersion of microparticles in nematic liquid crystals offers a novel means for controlling both their orientation and position through the combination of topology and external stimuli. Here, cuboidal and triangular prism shaped microparticles in parallel plate capacitor cells filled with a nematic liquid crystal are studied. Experimental observations are compared with numerical simulations to show...
ABO3 perovskite materials and their derivatives have inherent structural flexibility due to the corner sharing network of the BO6 octahedron, and the large variety of possible structural distortions and strong coupling between lattice and charge/spin degrees of freedom have led to the emergence of intriguing properties, such as high‐temperature superconductivity, colossal magnetoresistance, and improper...
Direct tracing of small extracellular vesicle (sEV) cargoes holds unprecedented importance for elucidating the mechanisms involved in intercellular communication. However, high‐fidelity determination of sEVs’ molecular cargoes in situ has yet to be achieved due to the difficulty in transporting molecular probes into intact sEVs. Herein, a fLuorescent Intracellular‐Guided Hairpin‐Tetrahedron (fLIGHT)...
In article number 2003815, Francesco Ciucci, Jang‐Kyo Kim, and co‐workers develop sodiophilicity gradient carbon foam skeletons to resolve the locally concentrated deposition of Na on the surface of 3D hosts. Both experiments and theoretical calculations reveal that the sodiophilicity gradient guides the “bottom‐up growth” of Na toward the top surface, demonstrating highly stable Na plating/stripping...
In article number 2003782, Jing Xia, Qipeng Lu, and co‐workers develop a general wet‐chemical method to synthesize a series of noble metal–based intermetallic nanocrystals, in which Br‐ ions play important roles in the formation of atomically ordered structures. The obtained Pd3Pb nanocubes exhibit superior electrocatalytic performance for ethanol and methanol oxidation reactions.
Ordered intermetallic nanomaterials with a well‐defined crystal structure and fixed stoichiometry facilitate the predictable control of their electronic structure and catalytic performance. To obtain the thermodynamically stable intermetallic structures, the conventional approaches with high‐temperature annealing are still far from satisfactory, because of annealing‐induced aggregation and sintering...
Metal–organic frameworks (MOFs) have attracted enormous research interest as precursors/templates to prepare catalytic materials. However, the effect of structural isomerism of MOFs on the catalytic performance has rarely been studied. In this contribution, two topologically different Ce‐benzene tricarboxylate (Ce‐BTC) based on the same ligands and metal centers (viz., “MOF isomers”) are prepared...
The energy transfer from plasmonic nanostructures to semiconductors has been extensively studied to enhance light‐harvesting and tailor light–matter interactions. In this study, the efficient energy transfer from an Au metasurface to monolayered MoS2 within a near‐field coupling regime is reported. The metasurface is designed and fabricated to demonstrate strong photoluminescence (PL) and cathodoluminescence...
Tumor vasculature and cancer stem cells (CSCs) accelerate the development of metastatic renal cancer. Dual inhibition of vascular endothelium and CSCs is still a challenge due to their different pathological features. Herein, a transformable dual‐inhibition system (TDS) based on a self‐assembly peptide is proposed to construct nanofibrous barriers on the cell membrane in situ, which contributes to...
Rhodium (Rh)‐based catalysts may solve the long‐standing inefficient oxidation of ethanol for direct ethanol fuel cells (DEFCs); however, the performance of ethanol oxidation reaction (EOR) on existing Rh‐based catalysts are far limited. Herein, the Rh–Pb catalysts are synthesized by building Pb and Pb oxide around Rh nanodomain, which shows highly efficient splitting CC bond and facile further oxidation...
The surface reconstruction of oxygen evolution reaction (OER) catalysts has been proven favorable for enhancing its catalytic activity. However, what is the active site and how to promote the active species generation remain unclear and are still under debate. Here, the in situ synthesis of CoNi incorporated Fe3N nanotubes (CoNi–Fe3N) on the iron foil through the anodization/electrodeposition/nitridation...
Tin disulfide (SnS2) shows promising properties toward sodium ion storage with high capacity, but its cycle life and high rate capability are still undermined as a result of poor reaction kinetics and unstable structure. In this work, phosphate ion (PO43−)‐doped SnS2 (P‐SnS2) nanoflake arrays on conductive TiC/C backbone are reported to form high‐quality P‐SnS2@TiC/C arrays via a hydrothermal–chemical...
Nanozymes with unique enzyme‐like catalytic properties and versatile functionalities are particularly attractive for the treatment of bacterial infections, especially for combating drug‐resistant bacteria. However, inherently low catalytic activity significantly limits their antibacterial performance. Herein, a new near‐infrared II (NIR‐II) light responsive nanozyme (Cu2MoS4 nanoplates, CMS NPs) is...
Developing efficient, inexpensive, and durable electrocatalysts for the oxygen reduction reaction (ORR) is important for the large‐scale commercialization of fuel cells and metal–air batteries.
