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...
Although ion‐interference therapy (IIT) has become an intriguing option for cancer treatment, the generation of interference ions on‐demand remains a challenge. Herein, a nanoplatform based on hierarchically mesoporous metal–organic frameworks (HMMOFs) is adopted to integrate black phosphorus quantum dots (BPQDs) and meso‐tetra(4‐carboxyphenyl) porphine (TCPP) to realize controllable phosphate anions...
The burden of bone fractures demands development of effective biomaterial solutions, while additional acute events such as noncompressible bleeding further motivate the search for multi‐functional implants to avoid complications including osseous hemorrhage, infection, and nonunion. Bone wax has been widely used in orthopedic bleeding control due to its simplicity of use and conformation to irregular...
Recent research shows that the continuing importance of carbon anode materials plays an important role in the development of sodium‐ion batteries. Nevertheless, the practical deployment of sodium‐ion batteries still faces many challenges such as mediocre sodium storage capability and short cycle life. Therefore, it is imperative to explore improvement methods to boost their competitiveness. Herein,...
Highly evolved substrate channels in natural enzymes facilitate the rapid capture of substrates and direct transfer of intermediates between cascaded catalytic units, thus rationalizing their efficient catalysis. In this study, a nanoscale ordered mesoporous Ce‐based metal–organic framework (OMUiO‐66(Ce)) is designed as an artificial substrate channel, where MnO2 is coupled to Ce–O clusters as a super‐active...
As an essential member of 2D materials, MXene (e.g., Ti3C2Tx) is highly preferred for energy storage owing to a high surface‐to‐volume ratio, shortened ion diffusion pathway, superior electronic conductivity, and neglectable volume change, which are beneficial for electrochemical kinetics. However, the low theoretical capacitance and restacking issues of MXene severely limit its practical application...
By taking advantage of the innate ability of the immune cells to target tumor cells, in article number 1603121, Cheng Dong, Jian Yang, and co‐workers develop a selfpowered immune cell‐mediated theranostic biodegradable photoluminescent poly (lactic acid) (BPLP‐PLA) nanoparticle‐based drug delivery system for melanoma targeting and drug delivery.
Although tremendous efforts have been made on targeted drug delivery systems, current therapy outcomes still suffer from low circulating time and limited targeting efficiency. The integration of cell‐mediated drug delivery and theranostic nanomedicine can potentially improve cancer management in both therapeutic and diagnostic applications. By taking advantage of innate immune cell's ability to target...
A facile in situ synthetic method is developed to synthesize metal sulfide nanoparticles based on 2D M‐TCPP (M = Cu, Cd, or Co, TCPP = tetrakis(4‐carboxyphenyl)porphyrin)) metal‐organic framework nanosheets. The obtained CuS/Cu‐TCPP composite nanosheet is used as the active material in photoelectrochemical cells, showing notably increased photocurrent due to the improved exciton separation and charge...
The high‐yield and scalable production of single‐layer ternary transition metal dichalcogenide nanosheets with ≈66% of metallic 1T phase, including MoS2xSe2(1–x) and MoxW1–xS2 is achieved via electrochemical Li‐intercalation and the exfoliation method. Thin film MoS2xSe2(1‐x) nanosheets drop‐cast on a fluorine‐doped tin oxide substrate are used as an efficient electrocatalyst on the counter electrode...
