In order to solve the problem that soluble polysulfide intermediates diffuse between cathode and anode during charging and discharging, which leads to rapid attenuation of battery cycle life, the separator modification materials come into people's sight. Herein, a mesoporous carbon‐supported cobalt‐nickel bimetal composite (CoNi@MPC) is synthesized and directly coated on the original separator to...
The emergence of Mo‐based hybrid zeolitic imidazolate frameworks (HZIFs) with MoO4 units brings substantial advantages to design and synthesize complex Mo‐based electrocatalyst that are not expected in their conventional synthesis path. Herein, as a newly proposed concept, a facile temperature‐induced on‐site conversion approach (TOCA) is developed to realize the transformation of MoO4 units to C‐Mo‐S...
Low‐cost and stable sodium‐layered oxides (such as P2‐ and O3‐phases) are suggested as highly promising cathode materials for Na‐ion batteries (NIBs). Biphasic hybridization, mainly involving P2/O3 and P2/P3 biphases, is typically used to boost their electrochemical performances. Herein, a P3/O3 intergrown layered oxide (Na2/3Ni1/3Mn1/3Ti1/3O2) as high‐rate and long‐life cathode for NIBs via tuning...
Despite the vast variety of colloidal superstructures available in soft matter photonics, it remains challenging to balance the trade‐off between their optical microstructures and material processability. By synergizing colloidal photonics and dynamic chemistry, a type of photonic “plasticine” with characteristics of uniform structural colors, high processability, and self‐healing is demonstrated...
Acute kidney injury (AKI) is frequently triggered by abundant reactive oxygen/nitrogen species (RONS) and leads to high morbidity and mortality in clinic. Unfortunately, the current clinical treatment options are only limited to supportive care, and hence, the development of nano‐antioxidants with high kidney enrichment is an attractive novel strategy for AKI management. Herein, self‐assembled ultrasmall...
In article number 2005113, Peng Huang and co‐workers develop biodegradable self‐assembled ultrasmall nanodots, which are composed of iron ion, gallic acid, and polyvinylpyrrolidone, as broad‐spectrum reactive oxygen/nitrogen species scavengers (RONS) with preferential kidney accumulation and rapid excretion to alleviate both glycerinum‐ and cis‐platinum‐induced acute kidney injury in mice.
Structure colored materials exhibit fabulous processing and handling properties. In article number 2007426, Ziyi Yu and co‐workers utilize boronic acid‐containing macromolecules to develop a type of “photonic plasticine” to build a highly cohesive, malleable, and soft matter that can be readily shaped without fractures.
With the progress of dissimilar dimensional materials, 1D and 2D materials have been extensively investigated as heterogeneous photocatalysts, which realize the unique dimensionality‐dependent advantages and mitigate the disadvantages during the environmental and sustainable energy applications. The progress in 1D/2D heterogeneous photocatalysts stems from the combination of different growth modes...
2D transition metal dichalcogenides (TMDs) have exhibited strong application potentials in new emerging electronics because of their atomic thin structure and excellent flexibility, which is out of field of tradition silicon technology. Similar to 3D p–n junctions, 2D p–n heterojunctions by laterally connecting TMDs with different majority charge carriers (electrons and holes), provide ideal platform...
Chemodynamic therapy (CDT) has attracted considerable attention recently, but the poor reaction kinetics restrict its practical utility in clinic. Herein, glucose oxidase (GOx) functionalized ancient pigment nanosheets (SrCuSi4O10, SC) for programmable near‐infrared II (NIR‐II) photothermal‐enhanced starvation primed CDT is developed. The SC nanosheets (SC NSs) are readily exfoliated from SC bulk...
Judicious tailoring of a robust interlayer is central to maintain the durable operation of optoelectronic devices. In this paper, an ultrathin, compact, and uniform PbI2 shell on the surface of perovskite via the method of ZnI2 aided in situ transformation is produced. The resultant PbI2 interlayer can prolong the excited‐state lifetime of perovskite and attenuate the recombination kinetics of separated...
The high‐temperature molten‐salt method is an important inorganic synthetic route to a wide variety of morphological phenotypes. However, its utility is limited by the fact that it is typically incapable of producing ultrathin (<5 nm diameter) nanowires, which have a crucial role in novel nanotechnology applications. Herein, a rapid molten salt‐based synthesis of sub‐5‐nm‐sized nanowires of hexagonal...

Ultrathin 2D molybdenum disulfide (MoS2), which is the flagship of 2D transition‐metal dichalcogenide nanomaterials, has drawn much attention in the last few years. 2D MoS2 has been banked as an alternative to platinum for highly active hydrogen evolution reaction because of its low cost, high surface‐to‐volume ratio, and abundant active sites.
