Seasonal influenza still greatly threatens public health worldwide, leading to significant morbidity and mortality. Antiviral medications for influenza treatment are limited and accompanied by increased drug resistance. In severe influenza virus infection, hyperinflammation and hypoxia may be the significant threats associated with mortality, so the development of effective therapeutic methods to...
Metal‐organic frameworks (MOFs) as a promising platform for electrocatalytic CO2 conversion are still restricted by the low efficiency or unsatisfied selectivity for desired products. Herein, zirconium‐based porphyrinic MOF hollow nanotubes with Cd sites (Cd‐PCN‐222HTs) are reported for electrocatalytic CO2‐to‐CO conversion. The dispersed Cd species are anchored in PCN‐222HTs and coordinated by N...
Designing a facile strategy to prepare catalysts with highly active sites are challenging for large‐scale implementation of electrochemical hydrogen production. Herein, a straightforward and eco‐friendly method by high‐energy mechanochemical ball milling for mass production of atomic Ru dispersive in defective MoS2 catalysts (Ru1@D‐MoS2) is developed. It is found that single atomic Ru doping induces...
The integration of highly luminescent CsPbBr3 quantum dots on nanowire waveguides has enormous potential applications in nanophotonics, optical sensing, and quantum communications. On the other hand, CsPb2Br5 nanowires have also attracted a lot of attention due to their unique water stability and controversial luminescent property. Here, the growth of CsPbBr3 nanocrystals on CsPb2Br5 nanowires is...
The electrochemical oxygen evolution reaction (OER) by efficient catalysts is a crucial step for the conversion of renewable energy into hydrogen fuel, in which surface/near‐surface engineering has been recognized as an effective strategy for enhancing the intrinsic activities of the OER electrocatalysts. Herein, a facile quenching approach is demonstrated that can simultaneously enable the required...
Recently, heterogeneous photocatalysts have achieved much interest on account of their great potential applications in resolving many tough energy and environmental troubles around the world through an ecologically sustainable way. Heterogeneous nanocomposites composed of graphitic carbon nitride (g‐C3N4) and carbon dots (CDs) possess broad spectrum absorption, appropriate electronic band structures,...
The poor stability, in particular with respect to temperature, moisture, and light exposure, remains a ubiquitous impediment virtually for metal halide perovskite materials and devices in their future practical application. Herein, from the perspective of precursor solution chemistry, ionic liquid solvent methylammonium acetate (MAAc) is introduced to prepare high‐quality MAPbBr3 perovskite thin films...
Bismuth ferrite (BiFeO3) has recently become interesting as a room‐temperature multiferroic material, and a variety of prototype devices have been designed based on its thin films. A low‐cost and simple processing technique for large‐area and high‐quality BiFeO3 thin films that is compatible with current semiconductor technologies is therefore urgently needed. Development of BiFeO3 thin films is summarized...
The release of metal ions may play an important role in toxicity of metal‐based nanoparticles. In this report, a life cycle study is carried out in a greenhouse, to compare the effects of ceria nanoparticles (NPs) and Ce3+ ions at 0, 50, 100, and 200 mg Ce kg−1 on plant growth, biological and physiological parameters, and nutritional value of soil‐grown common bean plants. Ceria NPs have a tendency...
Metal–organic frameworks (MOFs) are an interesting and useful class of coordination polymers, constructed from metal ion/cluster nodes and functional organic ligands through coordination bonds, and have attracted extensive research interest during the past decades. Due to the unique features of diverse compositions, facile synthesis, easy surface functionalization, high surface areas, adjustable porosity,...
Endophthalmitis, derived from the infections of pathogens, is a common complication during the use of ophthalmology‐related biomaterials and after ophthalmic surgery. Herein, aiming at efficient photodynamic therapy (PDT) of bacterial infections and biofilm eradication of endophthalmitis, a pH‐responsive zeolitic imidazolate framework‐8‐polyacrylic acid (ZIF‐8‐PAA) material is constructed for bacterial...
Topological crystalline insulators (TCIs) are predicted to be a promising candidate material for ultra‐broadband photodetectors ranging from ultraviolet (UV) to terahertz (THz) due to its gapless surface state and narrow bulk bandgap. However, the low responsivity of TCIs‐based photodetectors limits their further applications. In this regard, a high‐performance photodetector based on SnTe, a recently...
An intelligent theranostic nanoplatform based on nanovalve operated metal–organic framework (MOF) core–shell hybrids, incorporating tumorous microenvironment‐triggered drug release, magnetic resonance imaging (MRI) guidance, sustained release, and effective chemotherapy in one pot is reported. The core–shell hybrids are constructed by an in situ growth method, in which Fe3O4 particles with superior...
In article number 1603340, by Dingbin Liu and co‐workers, an interference‐free surface‐enhanced Raman scattering tag is constructed to profile the expression of cancer biomarkers at the single‐cell level. The Raman tags present a strong and sharp peak in the cellular Raman‐silent region, significantly diminishing the background interference. Moreover, the reporters are embedded in layered gold nanoparticles,...
