Vanadium‐based compounds are identified as promising cathode materials for aqueous zinc ion batteries due to their high specific capacity. However, the low intrinsic conductivity and sluggish Zn2+ diffusion kinetics seriously impede their further practical application. Here, oxygen vacancies on NH4V4O10 is reported as a high‐performing cathode material for aqueous zinc ion batteries via a facile hydrothermal...
Acetamide‐ or formamide‐assisted in situ strategy is designed to synthesize carbon atom self‐doped g‐C3N4 (AHCNx) or nitrogen vacancy‐modified g‐C3N4 (FHCNx). Different from the direct copolymerization route that suffers from the problem of mismatched physical properties of acetamide (or formamide) with urea, the synthesis of AHCNx (or FHCNx) starts from a crucial preorganization step of acetamide...
The integration of highly luminescent CsPbBr3 quantum dots on nanowire waveguides has enormous potential applications in nanophotonics, optical sensing, and quantum communications. On the other hand, CsPb2Br5 nanowires have also attracted a lot of attention due to their unique water stability and controversial luminescent property. Here, the growth of CsPbBr3 nanocrystals on CsPb2Br5 nanowires is...
Lithium–sulfur batteries are one of the most promising next‐generation energy storage systems. The efficient interconversion between sulfur/lithium polysulfides and lithium sulfide is a performance‐determining factor for lithium–sulfur batteries. Herein, a novel strategy to synthesize a unique tube‐in‐tube CNT‐wired sulfur‐deficient MoS2 nanostructure embedding cobalt atom clusters as an efficient...
Exploration of facile strategies for precise regulation of target gene expression remains highly challenging in the development of gene therapies. Especially, a stimuli‐responsive nanocarrier integrated with ability of noninvasive remote control for treating wide types of cancers is rarely developed. Herein, a NIR‐II absorbing semiconducting polymer (PBDTQ) is employed to remotely activate the heat‐inducible...
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...
In article number 2004548, Lei Wang, Ziqi Wang, Hao Wang, Wanhai Xu, and co‐workers propose a transformable dual‐inhibition system (TDS) based on a self‐assembly peptide to reduce metastasis of renal cancer via the inhibition of neovascular endothelial cells and cancer stem cells simultaneously. The TDS has great value in suppressing renal cancer metastasis. Additionally, this newly developed TDS...
Nanoporous TiNb2O7 (NPTNO) material is synthesized by a sol–gel method with an ionic liquid (IL) as the nanoporous structure directing template. NPTNO exhibits a high reversible capacity of 210 mAh g–1 even at the charging rate of 50 C and an excellent cyclability of half‐cell capacity retention of 74% for 1000 cycles at 5 C and LiNi0.5Mn1.5O4‐coupled full‐cell capacity retentions of 81% and 87% for...
Combination chemotherapy with time‐programmed administration of multiple drugs is a promising method for cancer treatment. However, realizing time‐programmed release of combined drugs from a single carrier is still a great challenge in enhanced cancer therapy. Here, an implantable trilayer structured fiber device is developed to achieve time‐programmed release of combined drugs for synergistic treatment...
Multiple drug resistance (MDR) of cancer cells is a major cause of chemotherapy failure. It is currently a great challenge to develop a direct and effective strategy for continuously inhibiting the P‐glycoprotein (P‐gp) drug pump of MDR tumor cells, thus enhancing the intracellular concentration of the therapeutic agent for effectively killing MDR tumor cells. Here, a new implantable hierarchical‐structured...
The degradation of intervertebral discs (IVD), a typical hierarchical structured tissue, causes serious neck and back pain. The current methods cannot fully reconstitute the unique structure and function of native IVD. In this study, by reverse reconstruction of the structure of native IVD and bioprinting bacterial cellulose (BC) nanofibers with a high‐throughput optimized micropattern screening microchip,...
Bacterial infections, especially multidrug‐resistant bacterial infections, are an increasingly serious problem in the field of wound healing. Herein, bacterial cellulose (BC) decorated by 4,6‐diamino‐2‐pyrimidinethiol (DAPT)‐modified gold nanoparticles (Au‐DAPT NPs) is presented as a dressing (BC‐Au‐DAPT nanocomposites) for treating bacterially infected wounds. BC‐Au‐DAPT nanocomposites have better...
In this paper, single crystalline copper nanowires (CuNWs) have been electrochemically grown through anodic aluminum oxide template. The environmental stability of the as‐obtained CuNWs in both 40% relative humidity (RH) atmosphere and 0.1 m NaOH aqueous solution has been subsequently studied. In 40% RH atmosphere, a uniform compact Cu2O layer is formed as a function of exposure time following the...
Despite the rapid increase of efficiency, perovskite solar cells (PSCs) still face some challenges, one of which is the current–voltage hysteresis. Herein, it is reported that yttrium‐doped tin dioxide (Y‐SnO2) electron selective layer (ESL) synthesized by an in situ hydrothermal growth process at 95 °C can significantly reduce the hysteresis and improve the performance of PSCs. Comparison studies...
Repeated photolithographic and etching processes allow the production of multileveled polymer microstructures that can be used as templates to produce bacterial cellulose with defined surfaces on demand. By applying this approach, the bacterial cellulose surface obtains new properties and its use for culturing neural stem cells cellulose substrate topography influences the cell growth in a defined...
