Bone infection poses a major clinical challenge that can hinder patient recovery and exacerbate postoperative complications. This study has developed a bioactive composite scaffold through the co‐assembly and intrafibrillar mineralization of collagen fibrils and zinc oxide (ZnO) nanowires (IMC/ZnO). The IMC/ZnO exhibits bone‐like hierarchical structures and enhances capabilities for osteogenesis,...
Synaptic devices that mimic biological synapses are considered as promising candidates for brain‐inspired devices, offering the functionalities in neuromorphic computing. However, modulation of emerging optoelectronic synaptic devices has rarely been reported.

Triple‐negative breast cancer (TNBC), one of the most aggressive types of breast cancer, currently lacks a targeted therapy and has a high clinical recurrence rate. The present study reports an engineered magnetic nanodrug based on Fe3O4 vortex nanorods coated with a macrophage membrane loaded with doxorubicin (DOX) and Enhancer of zeste 2 polycomb repressive complex 2 subunit (EZH2) siRNA. This novel...
The hierarchical Cu2S@NC@MoS3 heterostructures have been firstly constructed by the high‐capacity MoS3 and high‐conductive N‐doped carbon to co‐decorate the Cu2S hollow nanospheres. During the heterostructure, the middle N‐doped carbon layer as the linker facilitates the uniform deposition of MoS3 and enhances the structural stability and electronic conductivity. The popular hollow/porous structures...
Improved Lithium Sulfur Batteries
NiCo2S4‐x nanoplates with sulfur vacancy are grown on the flexible carbon fiber paper as the interlayer of the Li‐S battery. The 2D nanoplate morphology of NiCo2S4‐x increases the effective adsorption sites for lithium polysulfides (LiPSs), and the Lewis acidic sulfur vacancy could regulate the precipitation and conversion behaviors of LiPSs, resulting in improved...
The low conductivity of sulfur and the shuttle effect of lithium polysulfides (LiPSs) are the two intrinsic obstacles that limit the application of lithium–sulfur batteries (LSBs). Herein, a sulfur vacancy introduced NiCo2S4 nanosheet array grown on carbon nanofiber (CNF) membrane (NiCo2S4‐x/CNF) is proposed to serve as a self‐supporting and binder‐free interlayer in LSBs. The conductive CNF skeleton...
Constructing active heterointerfaces is powerful to enhance the electrochemical performances of transition metal dichalcogenides, but the interface density regulation remains a huge challenge. Herein, MoO2/MoS2 heterogeneous nanorods are encapsulated in nitrogen and sulfur co‐doped carbon matrix (MoO2/MoS2@NSC) by controllable sulfidation. MoO2 and MoS2 are coupled intimately at atomic level, forming...
Just as the heterojunctions in physics, donor–acceptor (D‐A) heterostructures are an emerging class of photoactive materials fabricated from two semiconductive components at the molecular level. Among them, D‐A hybrid heterostructures from organic and inorganic semiconductive components have attracted extensive attention in the past decades due to their combined advantages of high stability for the...
High energy density and long cycle life of lithium–sulfur (Li–S) batteries suffer from the shuttle/expansion effect. Sufficient sulfur storage space, local fixation of polysulfides, and outstanding electrical conductivity are crucial for a robust cathode host. Herein, a modified template method is proposed to synthesize a highly regular and uniform nitrogen/oxygen dual‐doped honeycomb‐like carbon...
As a common nuclide in radioactive wastewater, uranium (U) is generally treated by landfill, which induces the massive abandonment of uranium resources. In this work, a pulse voltammetry method for the synthesis of U single atoms on MoS2 (U/MoS2) nanosheets from radioactive wastewater for the electrocatalytic alkaline hydrogen evolution reaction (HER) is reported. The mass loading of U single atoms...

In article number 2107444, Yan Liu, Rong He, Wenkun Zhu, and co‐workers construct a pulse voltammetry method to directly prepare uranium (U) single atoms on the edge sites of MoS2 nanosheets (U/MoS2) from radioactive wastewater. The 5.2% U/MoS2 nanosheet displayed a low overpotential of 72 mV at 10 mA cm−2 in 1 M KOH solution. Furthermore, the boosted hydrogen evolution reaction...
To develop methods to generate, manipulate, and detect plasmonic signals by electrical means with complementary metal–oxide–semiconductor (CMOS)‐compatible materials is essential to realize on‐chip electronic–plasmonic transduction. Here, electrically driven, CMOS‐compatible electronic–plasmonic transducers with Al–AlOX–Cu tunnel junctions as the excitation source of surface plasmon polaritons (SPPs)...
Antimony is an attractive anode material for sodium‐ion batteries (SIBs) owing to its high theoretical capacity and appropriate sodiation potential. However, its practical application is severely impeded by its poor cycling stability caused by dramatic volumetric variations during sodium uptake and release processes. Here, to circumvent this obstacle, Sb@C@TiO2 triple‐shell nanoboxes (TSNBs) are synthesized...
Cisplatin is a first‐line drug in clinical cancer treatment but its efficacy is often hindered by chemoresistance in cancer cells. Reduced intracellular drug accumulation is revealed to be a major mechanism of cisplatin resistance. Nanoscale drug delivery systems could help to overcome this problem because of their more active cellular uptake and more accurate tumor localization. DNA nanostructures...
In biological systems, nature enzymes work together in an efficacious way to undertake metabolic processes by confining cooperating enzymes within compartments.

Locating nanotherapeutics at the active sites, especially in the subcellular scale, is of great importance for nanoparticle‐based photodynamic therapy (PDT) and other nanotherapies. However, subcellular targeting agents are generally nonspecific, despite the fact that the accumulation of a nanoformulation at active organelles leads to better therapeutic efficacy. A PDT nanoformulation is herein designed...
