Al‐Si dealloying method is widely used to prepare Si anode for alleviating the issues caused by a drastic volume change of Si‐based anode. However, this method suffers from the problems of low Si powder yield (<20 wt.% Si) and complicated cooling equipment due to the hindrance of large‐size primary Si particles. Here, a new modification strategy to convert primary Si to 2D SiOx nanosheets by introducing...
Wounds and the subsequent formation of scars constitute a unified and complex phased process. Effective treatment is crucial; however, the diverse therapeutic approaches for different wounds and scars, as well as varying treatment needs at different stages, present significant challenges in selecting appropriate interventions. Microneedle patch (MNP), as a novel minimally invasive transdermal drug...
Stable plating/stripping of Zn metal anode remains a great challenge owing to uncontrollable dendrite growth and side reactions. Ion‐sieving separators is a unique and promising solution, that possess Zn2+ permeability and promote Zn2+ transport, can effectively alleviate the abovementioned problems. Ion‐sieving on glass fiber separator by deposition of oxygen‐deficient SiOx layer via active screen...
Animals with robust attachment abilities commonly exhibit stable attachment and convenient detachment. However, achieving an efficient attachment–detachment function in bioinspired adhesives is challenging owing to the complexity and delay of actuators. In this study, a class of multilayer adhesives (MAs) comprising backing, middle, and bottom layers is proposed to realize rapid switching by only...
The development of bifunctional catalysts that facilitate both the hydrogen evolution reaction (HER) and hydrogen oxidation reaction (HOR) in alkaline environment is crucial for realizing unitized regenerative anion‐exchange membrane fuel cells. In this study, a novel strategy to modulate the electron density of MoO3 through Ni doping (sample named NixMo1−xO3) is reported. Ni is incorporated to replace...
Rechargeable sodium ion batteries (SIBs) have promising applications in large‐scale energy storage systems. Iron‐based Prussian blue analogs (PBAs) are considered as potential cathodes owing to their rigid open framework, low‐cost, and simple synthesis. However, it is still a challenge to increase the sodium content in the structure of PBAs and thus suppress the generation of defects in the structure...
Chiral organic−inorganic hybrid metal halide materials have shown great potential for circularly polarized luminescence (CPL) related applications for their tunable structures and efficient emissions. Here, this work combines the highly emissive Cu4I4 cubane cluster with chiral organic ligand R/S‐3‐quinuclidinol, to construct a new type of 1D Cu‐I chains, namely Cu4I4(R/S‐3‐quinuclidinol)3, crystallizing...
It is a good idea for efficient production of hydrogen to use ethanol oxidation reaction (EOR) in place of oxygen evolution reaction (OER) in water electrolysis process. Ni‐based non‐precious electrocatalysts are widely used in the conversion of ethanol to acetic acid. Here, different selenide heterostructures (NiCoSe, NiFeSe, and NiCuSe) are prepared in which Ni sites are regulated by transition...
The high cost and scarcity of lithium resources have prompted researchers to seek alternatives to lithium‐ion batteries. Among emerging “Beyond Lithium” batteries, rechargeable aluminum‐ion batteries (AIBs) are yet another attractive electrochemical storage device due to their high specific capacity and the abundance of aluminum. Although the current electrochemical performance of nonaqueous AIBs...
Solid electrolytes are considered as an ideal substitution of liquid electrolytes, avoiding the potential hazards of volatilization, flammability, and explosion for liquid electrolyte–based rechargeable batteries. However, there are significant performance gaps to be bridged between solid electrolytes and liquid electrolytes; one with a particular importance is the ionic conductivity which is highly...
Poor cycling stability and rate capability are two key issues needing to be solved for Li‐ and Mn‐rich oxide cathode material for lithium‐ion batteries (LIBs). Herein, a novel perovskite electron–ion mixed conductor Nd0.6Sr0.4CoO3 (NSCO) is used as the coating layer on Li1.2Ni0.13Co0.13Mn0.54O2 (LNCMO) to simultaneously enhance its cycling stability and rate capability. By coating 3 wt% NSCO, LNCMO–3NSCO...
Structures comprising high capacity active material are highly desirable in the development of advanced electrodes for energy storage devices. However, the structure degradation of such material still remains a challenge. The construction of amorphous and crystalline heterostructure appears to be a novel and effectual strategy to figure out the problem, owing to the distinct properties of the amorphous...
In article number 1801905, Jinlong Shi, Rongqin Huang, Wei Shi, and co‐workers describe a novel drug‐loaded system, OPPD, which uses PEG and OMCN linked to the Pep22 polypeptide targeting the low‐density lipoprotein receptor, that can effectively cross the blood‐brain barrier and target glioma cells, exerting an outstanding therapeutic efficacy via both the near‐infrared photothermal and chemotherapeutic...
Accumulating studies have investigated the efficacy of receptor‐mediated delivery of hydrophobic drugs in glioma chemotherapy. Here, a delivery vehicle comprising polyethylene glycol (PEG) and oxidized nanocrystalline mesoporous carbon particles (OMCN) linked to the Pep22 polypeptide targeting the low‐density lipoprotein receptor (LDLR) is designed to generate a novel drug‐loaded system, designated...
Black phosphorus nanobelts are fabricated with a one‐step solid–liquid–solid reaction method under ambient pressure, where red phosphorus is used as the precursor instead of white phosphorus. The thickness of the as‐fabricated nanobelts ranges from micrometers to tens of nanometers as studied by scanning electron microscopy. Energy dispersive X‐ray spectroscopy and X‐ray diffraction indicate that...
Innovative nanoparticles hold promising potential for disease therapy as drug delivery systems. For brain‐disease therapy, a drug delivery system that can sustainably control drug‐release and monitor fluorescence of the drug cargos is highly desirable. In this study, a light‐traceable and intracellular microenvironment‐responsive drug delivery system was developed based on the combination of glutathione‐responsive...
