Engineering the catalytic performance of nanozymes is of vital importance for their broad applications in biological analysis, cancer treatment, and environmental management. Herein, a strategy to boost the peroxidase‐like activity of Pd‐based nanozymes with oxophilic metallic bismuth (Bi) is demonstrated, which is based on the incorporation of oxophilic Bi in the Pd‐based alloy nanocrystals (NCs)...
Cell engineering, soft robotics, and wearable electronics often desire soft materials that are easy to deform, self‐heal readily, and can relax stress rapidly. Hydrogels, a type of hydrophilic networks, are such kind of materials that can be made responsive to environmental stimuli. However, conventional hydrogels often suffer from poor stretchability and repairability. Here, hydrogels consisting...
Bacterial biofilm‐related infectious diseases severely influence human health. Under typical situations, pathogens can colonize inert or biological surfaces and form biofilms. Biofilms are functional aggregates that coat bacteria with extracellular polymeric substances (EPS). The main reason for the failure of biofilm infection treatment is the low permeability and enrichment of therapeutic agents...
Owing to the high power density, eco‐friendly, and outstanding stability, the lead‐free ceramics have attracted great interest in the fields of pulsed power systems. Nevertheless, the low energy storage density of such ceramics is undoubtedly a severe problem in practical applications. To overcome this limitation, the lead‐free ceramics with gradient structures are designed and fabricated using the...
The rapid, simple and low‐cost preparation of DNA micro‐nano‐architectures remain challenging in biosensing and therapy. Polymerase chain reaction (PCR)‐driven DNA micro‐nano‐flowers are used to construct a nanosized baicalin‐compressed‐aptamer‐nanodrug (bcaND) via one‐pot assembly for targeted and synergistic anti‐obesity. In the design, the tailored Adipo‐8 (tAdi‐8) overhang in the PCR amplicon...
Metal boride nanostructures have shown significant promise for hydrogen storage applications. However, the synthesis of nanoscale metal boride particles is challenging because of their high surface energy, strong inter‐ and intraplanar bonding, and difficult‐to‐control surface termination. Here, it is demonstrated that mechanochemical exfoliation of magnesium diboride in zirconia produces 3–4 nm ultrathin...
Metallic micro/nano structures with special physicochemical properties have undergone rapid development owing to their broad applications in micromachines and microdevices. Ultrafast laser processing is generally accepted as an effective technology for functional structures manufacture, however, the controllable fabrication of specific metallic micro/nano structures remains a challenge. Here, this...
Green ammonia is an efficient, carbon‐free energy carrier and storage medium. The ammonia synthesis using green hydrogen requires an active catalyst that operates under mild conditions. The catalytic activity can be promoted by controlling the geometry and electronic structure of the active species. An exsolution process is implemented to improve catalytic activity by modulating the geometry and electronic...
Nanopore brings extraordinary properties for a variety of potential applications in various industrial sectors. Since manufacturing of solid‐state nanopore is first reported in 2001, solid‐state nanopore has become a hot topic in the recent years. An increasing number of manufacturing methods have been reported, with continuously decreased sizes from hundreds of nanometers at the beginning to ≈1 nm...
Solid catalyst is widely recognized as an effective strategy to control the chirality of single‐walled carbon nanotubes (SWNTs). However, it is still not compatible with high density in horizontal arrays. “Trojan” catalysts strategy is one of the most effective methods to realize SWNTs with high density and has great potential in chirality control. Here, the co‐realization of high density and chirality...

The ability to control the density and spatial distribution of substitutional dopants in semiconductors is crucial for achieving desired physicochemical properties. Substitutional doping with adjustable doping levels has been previously demonstrated in 2D transition metal dichalcogenides (TMDs); however, the spatial control of dopant distribution remains an open field. In this work, edge termination...
Structural engineering via the template method is efficient for micro‐nano assembling. However, only structural design and lack of composition control restrict their advanced application. To overcome this issue, applying a template to simultaneously realize the structural design and fine component control is highly desired, which has been ignored.
