Sustainable and scalable solar‐energy‐driven CO2 conversion into fuels requires earth‐abundant and stable photocatalysts. In this work, a defective Nb2C MXene as a cocatalyst and TiO2 microspheres as photo‐absorbers, constructed via a coulombic force‐driven self‐assembly, is synthesized. Such photocatalyst, at an optimized loading of defective Nb2C MXene (5% def‐Nb2C/TiO2), exhibits a CH4 production...
2D layered magnets, such as iron chalcogenides, have emerged these years as a new family of unconventional superconductors and provided the key insights to understand the phonon‐electron interaction and pairing mechanism. Their mechanical properties are of strategic importance for the potential applications in spintronics and optoelectronics. However, there is still a lack of efficient approach to...
Restoring immune tolerance is the ultimate goal for rheumatoid arthritis (RA) treatment. The most reported oral or intravenous injection routes for the immunization of autoantigens cause gastrointestinal side effects, low patient compliance, and unsatisfied immune tolerance induction. Herein, the use of a transdermal microneedle patch is for the first time investigated to codeliver CII peptide autoantigen...
As one of promising candidates for large‐scale energy‐storage systems, Zn‐I2 aqueous battery exhibits multifaceted advantages including low cost, high energy/powder density, and intrinsic operational safety, but also suffers from fast self‐discharge and short cycle/shelf lifespan associating with I3− shuttle, Zn dendrite growth, and corrosion. In this paper, the battery's self‐discharge rate is successfully...
The ternary strategy is one of the effective methods to regulate the morphology of the active layer in organic solar cells (OSCs). In this work, the ternary OSCs with bulk heterojunction (BHJ) or layer‐by‐layer (LbL) active layers are prepared by using the polymer donor PM6 and the non‐fullerene acceptor L8‐BO as the main system and the fullerene acceptor PC71BM as the third component. The power conversion...
Design of highly efficient electrocatalysts for alkaline hydrogen evolution reaction (HER) is of paramount importance for water electrolysis, but still a considerable challenge because of the slow HER kinetics in alkaline environments. Alloying is recognized as an effective strategy to enhance the catalytic properties. Lanthanides (Ln) are recognized as an electronic and structural regulator, attributed...
A novel semiconductive Co/Fe‐MOF embedded with Fe2O3 nanocrystals (Fe2O3@CoFe‐MOF) is developed as a trifunctional electrocatalyst for the urea oxidation reaction (UOR), oxygen evolution reaction (OER), and hydrogen evolution reaction for enhancing the efficiency of the hydrogen production via the urea‐assisted overall water splitting. Fe2O3@CoFe‐TPyP‐MOF comprises unsaturated metal‐nitrogen coordination...
The efficacy of immune checkpoint blockade (ICB) in promoting an immune response against tumors still encounters challenges such as low response rates and off‐target effects. Pyroptosis, an immunogenic cell death (ICD) mechanism, holds the potential to overcome the limitations of ICB by activating and recruiting immune cells. However, the expression of the pyroptosis‐related protein Gasdermin‐E(GSDME)...
The design and fabrication of NO‐evolving core‐shell nanoparticles (denoted as NC@Fe), comprised of BNN6‐laden COF@Fe3O4 nanoparticles, are reported. This innovation extends to the modification of 3D printed polyetheretherketone scaffolds with NC@Fe, establishing a pioneering approach to multi‐modal bone therapy tailored to address complications such as device‐associated infections and osteomyelitis...
Cuproptosis is a novel form of regulated cell death which guarantees to increase the efficacy of existing anticancer treatments that employ traditional apoptotic therapeutics. However, reducing the amount of undesirable Cu ions released in normal tissue and maximizing Cu‐induced cuproptosis therapeutic effects at tumor sites are the major challenges. In this study, exploiting the chemical properties...
In surface‐enhanced Raman spectroscopy (SERS), 2D materials are explored as substrates owing to their chemical stability and reproducibility. However, they exhibit lower enhancement factors (EFs) compared to noble metal‐based SERS substrates.

Direct ethanol fuel cells hold great promise as a power source. However, their commercialization is limited by anode catalysts with insufficient selectivity toward a complete oxidation of ethanol for a high energy density, as well as sluggish catalytic kinetics and low stability. To optimize the catalytic performance, rationally tuning surface structure or interface structure is highly desired. Herein,...
It is challenging yet promising to design highly accessible N‐doped carbon skeletons to fully expose the active sites inside single‐atom catalysts. Herein, mesoporous N‐doped carbon hollow spheres with regulatable through‐pore size can be formulated by a simple sequential synthesis procedure, in which the condensed SiO2 is acted as removable dual‐templates to produce both hollow interiors and through‐pores,...
Perovskite solar cells have achieved rapid progress in the new‐generation photovoltaic field, but the commercialization lags behind owing to the device stability issue under operational conditions.
